2 . A b o u t Q u a n t r a
Quantra is a high quality natural quartz stone that is solid, non-porous, homogenous and highly durable and resistant to scratching, staining and water absorption and is virtually maintenance free. Quantra is twice as impact resistant as & four times stronger than natural stone.
2.1 Quantra is composed of upto ~93 % premium grade pure quartz and ~7% high quality polyester resin. Quantra is coloured using finest quality pigments which ensure the consistency of colour from batch to batch.
2.2 Quantra has an outstanding physical-mechanical and chemical properties in its entire mass.
2.3 Quantra:
2.3.1 does not stain, chip or sratch easily;
2.3.2 does not support mildew and mold;
2.3.3 has superior impact resistance;
2.3.4 is colour consistent and hence allows coordinated applications;
2.3.5 is easy to maintain;
2.3.6 is heat resistant;
2.3.7 is immune to freezing and thawing cycle;
2.3.8 is non porous and resists growth of bacteria and fungi;
2.3.9 is resistant to many household chemicals, solvents and acid;
2.3.10 is strong, durable and yet beautiful!
2.4 Quantra is manufactured using the world renowned BRETONSTONE® SYSTEM. It is the exclusive technology, patented by Breton S.p.A., Italy of "Compaction by Vibrocompression Under Vacuum" which makes it possible to work and compact dry mixtures formed by stone aggregates and binding paste into compound stone of the highest quality "Natural quartz".Quantra is manufactured directly into slabs of various thicknesses and dimensions. The quality of natural quartz surfaces vary from brand to brand depending on the quality of resin and raw materials used during the manufacturing of the stone. Quantra is manufactured using high quality raw materials as per the specification and recommendation of Breton. PESL’s plant is the most modern and robotic.
2.5 The major advantages of the BRETONSTONE®SYSTEM process are:
2.5.1 There is possibility of using correct ratio among the components of mixture to be compacted;
2.5.2 There is the absence of air in the mixtures to be compacted and during the compaction phase;
2.5.3 There is combined action under vacuum of vibration and compression of the mixtures.
2.6 BRETONSTONE®SYSTEM is the only patented system in the world that makes it possible to transform dry mixtures into compound stone materials, perfectly compacted.
2.7 The aesthetic visual of the finished products is created by the synergy of the nature, size and colour of the stone materials combining with the colouring, composition and blending of the
5
mixtures. Alternative materials such as glass, mirrors, brass, mother of- pearl or suchlike can be added to the mixture to create more attractive and innovative products.
2.8 The designer’s creative imagination is the only restriction to the numberless aesthetic, chromatic and functional possibilities that Quantra can feature. Colours and sizes can be chosen and combined together, according to various requirements of the designers and architects. The surface finish can be changed depending on the customer’s requests in order to supply honed, sandblasted, velvet or otherwise finished products.
3. Manufacturing Process
3.1 In the first step of manufacturing Quantra, the three main ingredients, quartz, pigments and polymer are thoroughly mixed. This mixture is subsequently moved to the so-called ‘lay-down’ area where the mixture is compressed and vibrated (vibro-compacted) in a vacuum. The combined action of VIBRATION and COMPRESSION makes it possible for the aggregates to compact very close to each other so as to minimise the interstices for the optimal arrangement of solid particles in the mixture. Therefore, the quantity of binding paste needed to hold the aggregates together is reduced whilst the mechanical characteristics of the product are increased. The COMPACTION UNDER VACUUM eliminates the presence of any MACROPOROSITY in the compacted mixture and of any MICROPOROSITY in the binding paste, minimising water absorption down to 0.03% by weight.
3.2 After compaction the slabs move through a curing tower in which the uncured resin transforms into solid polymer. After cooling down, the slabs are trimmed and subsequently go through a series of wet abrasive grinding steps. The first step is designed to gauge the slab to the desired thickness. In the next steps finer abrasives are used to obtain the final surface polish. Finally all the slabs undergo a stringent final inspection before moving to a storage facility.
3.3 The end result is Quantra, a compound material, not existing in nature, which represents an ideal product for the modern building industry.
3.4 PESL is equipped with the plant to manufacture Quantra natural quartz surface with veined appearance. It is possible to design and manufacture products having special made-to-measure aesthetic visuals to meet even the most refined demands of architects and users.
3.5 PESL is equipped with its own centre for the research and development of Quantra natural quartz surface. Every day, a team of technical experts carry out continuous researches on developing new Quantra products.
3.6 PESL places its research and development centre at the customer’s disposal for performing physical-chemical testing on the materials.
3.7 Not only does Quantra faithfully replicate genuine granite and marble varieties, which makes it a great alternative option to “the real thing”, it also features a number of outstanding technical properties. Technical Data of Quantra is given herein below for ready reference:

4.1 Quantra is available in large slabs measuring 3050mm x 1400mm (120" x 55") in the thickness of 20mm ( ¾” ), 30mm(1 ¼” ) +/- 1.5mm. Quantra slabs are also available, as special order, in 12mm ( ½”) thickness. The thickness may vary by +/- 1.5mm. The length may vary by +/- 20mm and the width may vary by +/- 10mm.
4.2 Each slab is produced with a purposely tapered edge to accommodate any mild edge damage that may occur during handling and transportation.
4.3 Quantra tiles are available in thickness of 12mm ( ½”) in varied sizes of :
4.3.1 300 mm x 300 mm (12" x 12")

4.3.4 400 mm x 600 mm (16" x 24")
4.3.5 600 mm x 600 mm (24" x 24")
4.4 Selection of thickness would largely depend on the application for which Quantra is to be used.
4.4.1 For laying Quantra on standard loaded area, it is recommended that the following thickness parameters are used:
Product dimensions (mm ) Minimal recommended product thickness (mm )
up to 600 x 600 10
Larger and non-standard dimensions The solution has to take the project conditions, installation and load into account - 12 – 20 mm
4.4.2 For laying Quantra on raised floors, it is recommend that the following thickness parameters are used:
Recommended dimensions of the product (mm)
Minimum recommended thickness (mm)
up to 600 x 600 20
more than 600 x 600 30
4.4.3 For cladding Quantra on inner wall it is necessary to take the mass of the product into account. In case of cladding using adhesive it is recommended that the following thickness parameters are used (recommended height up to max. 2,5 m):
Recommended dimensions of the product (mm)
Minimum recommended thickness (mm)
300 x 300 10
4.4.4 For cladding Quantra on inner wall it is necessary to take the mass of the product into account. In case of cladding on supporting mounted grates, it is recommended that the following thickness parameters are used:

i. For cladding Quantra on inner wall it is necessary to take the mass of the product into account. In case of Anchored cladding, it is recommended that the following thickness parameters are used:
Dimensions of the product (mm) Minimum recommended thickness (mm)
up to 600 x 600 30, exceptionally 20 (according to the system) more than 600 x 600 30
ii. For using Quantra as a stair component it is recommended that the following thickness parameters are used:
Method of laying Minimum recommended thickness (mm)
Whole face on substrate concrete 10 - 20
Into construction, self-supporting 30
iii. In case Quantra is used as a countertop, the thickness should be minimum of 20mm. It is important to note that larger the thickness, the higher would be the strength and thermal resistance.
a. Quantra is available in different finishes. Standard slab/tile finish is polished or gloss finished. It is possible to provide custom finishes like honed or matt,easy care, slate, caress, velvet, egg, and sandblasted. It is important to note that finishes may change performance of Natural quartz surface. Quantra Tiles are calibrated for both dimension and thickness and bevelled around the edges.
b. Quantra provides excellent colour consistency between slabs from the same lot number. As any other quartz surfacing product, slabs from different lot numbers may have a slight difference in colour shade. The composition of natural quartz and granite particles used in the products may sometimes produce minor irregularities such as crazing in the grains, blotches, spots, coloured particles. Such imperfections are generally accepted by the industry.
c. PESL recommends that depending on the abrasive load of the floor the type of finish should be decided. Different load conditions are given below:
i. Heavy load is an area which is subject to heavy traffic and or high presence of abrasive and liquid contaminants. Example – installations in entrances and exits from the buildings and halls, in front of cash desks, receptions, counters, in underpasses, covered platforms, etc.
ii. Medium load is an area which is subject to heavy traffic without higher presence of abrasive contaminants. Example - installation in shops, offices, halls, corridors, etc.
iii. Low load is an area which is subject to medium traffic without the presence of abrasive contaminants. Example -installation in residences, internal offices, halls, decorative places, etc.

respect to the expected usage of the product.
5 . A p p l i c a t i o n s
5.1 Quantra is available in a pedantically created colour palette that can be used in a variety of residential and commercial applications.
5.2 Quantra allows architects and designers to explore creativity surpassing what is possible with the other stones. Quantra with its lively refreshing colors, look and technically superior qualities subtly interacts with the light, capturing and reflecting the radiance of quartz crystal. As an added bonus, the material harmonizes beautifully with wood, glass, steel and concrete.
5.3 Quantra can be used in various applications due to its characteristics and dimensions. Due to its aesthetics, quality and durability it can be used for kitchen countertops, bar tops, laboratory tops, bathroom vanities, bathroom partitions, tub and shower surrounds, flooring, stair treads, walls, furniture tops, back splashes and also wherever high quality, sanitary and maintenance-free flooring or tops are required. The uniformity of colouring permits additional, coordinated applications.
5.4 Quantra with its unusual clarity and colour consistency offers a great potential for both horizontal and vertical applications.
5.5 Quantra being non porous does not support the growth of bacteria or fungi and hence is hygienic.

6. Flooring Application
Because of its physical-chemical characteristics, Quantra is preferred to any other material to make floors or surfaces that require particularly heavy performances:
6.1 Quantra can be laid either in small or large, thick, medium or thin sizes. It is best suited for homes, hospitals, schools, hotels, barracks, chemical laboratories, shopping centres, dairies, grocer's and butcher's shops, factories of any sector, public and private offices, subways, railway stations, airports, etc…
6.2 Quantra has a required flexural strength and hence can be used in thin tiles with thickness even lower than 9 millimetres and can be glued, pre-polished, on pre-existing floors. As other surface floors it can be honed and polished again after many years of intense use;
6.3 It is possible to make access raised floors using Quantra slab of 20/30 mm thickness, without placing them on a supporting element. This means savings and easy installation!
7. Cladding
Quantra is recommended for exterior application provided the surface is coated with special surface chemicals. Quantra without such special surface chemicals is not recommended for any areas that is exposed to direct sunlight or Ultra Violet radiation as exposure to direct sunlight for prolonged periods can result in colour changes or fading and warping. In order to avoid this phenomenon, Breton has developed a specific permanent surface treatment. We have an ultra modern line to coat Quantra with special surface chemicals to make Quantra suitable for exterior application. The effect of UV rays is quite imperceptible if Quantra applied outdoors has a sandblasted, scratched, bush-hammered or untreated finish.
Quantra in correct finish is suitable for exterior cladding as its structural features are not affected by atmospheric agents (acid rain, freezing/thaw, cold and heat, sun-beams, etc.).
8. Table tops, Kitchen and Bar Counters, Vanity Tops
8.1 Kitchen and bar counters, vanity tops, table tops for corporate offices, hotels, shops, supermarket, banks, airports, etc., are required to strong, durable and at the same time, be highly decorative. Quantra Natural Quartz surface responds to this dual function of resistance and decoration.
8.2 Quantra can be cut and installed to meet design requirements, with precision, uniformity and consistency, using special tools made for quartz surfaces. Quantra is available in different edge profiles.
8.3 Due to the innovative ways the product can be used, Quantra is a right choice for design projects of all types.

10.1 It is important to follow the correct fixing methods suitable for the specific applications. Quantra should NOT be laid using customary sand and cement. There are no established Indian standard for adhesive fixing of engineered quartz stone slabs / tiles. Installers in India may fix the engineered quartz stone slabs / tiles similar to fixing ceramic tiles using adhesives meant for ceramic tiles. Such practices leads to failure in installation.
10.2 Do not alter factory finish or polish. No repolishing or refinishing should be done on the Quantra Natural Quartz Surface.
10.3 Method adopted for laying of engineered quartz stone slabs / tiles may vary from location to location and may be installed in numerous ways. It is of prime importance that the installer takes into account the features viz. differential movement, structural deflections, foundation movements, thermal movements, moisture movements, dimensional stability of the materials that make up the different layers of the engineered quartz stone slabs / tiles and understand how they interact with each other if the complete system has to perform successfully.
10.4 It is the responsibility of the installer/ buyer to design the tiling system based on the advice obtained from the adhesive manufactures.
10.5 Quantra tiles are generally supplied calibrated, squared, polished and chamfered and are absolutely ready to be laid. We recommend usage of specially designed Polymer modified rapid setting cement adhesive confirming to ANS118.4 – 1999 having below mentioned performance properties for bonding of engineered quartz stone slabs / tiles:
Test ANSI 118.4
Initial Set >6 hr
Final Set 9 – 15 hr
28 day shear bond 200 psi
28 day compressive 2500
10.6 For high demanding areas such as heavy traffic areas & critical installations we recommend usage of specially designed epoxy based adhesive having below mentioned performance properties for bonding of engineered quartz stone slabs / tiles :
Test ANSI 118.3
Setting time > 2 hr 28 day shear bond 150 psi
28 day compressive 2500 psi ANSI 118.3 F-6.1 modified
We recommend that the following procedure may be followed for laying Quantra tiles:
13
11. Preparing the Substrate
11.1 Tiles must be laid on concrete floor which is dry and moisture free, flat, stable, solid, free of cracks, smooth, clean of any dust, debris, oils or any similar substances that may cause tiles to break free.
11.2 During the laying process, the environmental temperature must be between +50C and +300C.
11.3 Sand and cement screeded floors must be allowed to dry for such no. of days that the surface is completely cured and free of moisture. Laying the tiles on wet sand and cement mixture is to be utterly avoided. The humidity of the concrete at the most be less than 5% before the installation.
11.4 Polymer modified rapid setting cement adhesiveused should be such that adhesive and waterproofing membrane are compatible. If this is not possible epoxy based adhesive should be used.
11.5 Polymer modified rapid setting cement adhesiveshall be prepared as instructed by the adhesive manufacturer.
11.6 Remember to check tackiness of the mixture spread on the foundation. The tackiness of the mixture spread on the foundation should be tested by hand. If the adhesive smudge onto fingers, installation of tiles can be continued; if not the foundation must be thoroughly cleansed off and a new adhesive must be re-spread on the foundation.
11.7 Using flat side of the trowel to make a thin layer of polymer modified rapid setting cement adhesive(bed thickness as recommended by supplier) on the foundation.
11.8 Spread the appropriate amount of polymer modified rapid setting cement adhesiveat one time to ensure that the tiles are laid within the setting time of the adhesive.
11.9 For good adhesion, the polymer modified rapid setting cement adhesivemust be spread as a thin layer (back buttering) on the back of the tile.
11.10 The tile should then be layed on the polymer modified rapid setting cement adhesivecovered foundation and should be tapped with a rubber mallet to ensure even laying.
11.11 Tiles must be always layed with joints. Joints must have a minimum width of 2 mm for 300 mm x300 mm and 600 mm x600 mm tiles.
11.12 Grouting of the joints should be done at least 24 hours after laying of the tile. The joints should be thoroughly cleaned before grouting.
11.13 Grout should be cleaned from the surface within 15 mins.
11.14 Always remember to seal joints with a flexible cement based grout having below the mentioned performance properties:
Test ANSI 118.6 Linear shrinkage 7 days < 0.10% Flexural strength 7 days 400 psi Tensile strength 28 days 350 psi Compressive strength 28 days 3000 psi
14
11.15 For high demanding areas such as heavy traffic areas & critical installations we recommend usage of specially designed epoxy based stainfree & water cleanable grout having below mentioned performance properties :
Test ANSI 118.3
Water cleanability > 80min (E-5.1)
Initial setting time > 2 hr (E-5.2)
Linear Shrinkage <0.25% (E-5.3)
Sag No change (E-5.4)
Shear bond strength >1000 psi (E-55)
Compressive strength 3500 psi (E-66)
Tensile strength 1000 psi (E-5.7)
Thermal shock > 500 psi (E-5.8)
11.16 Grouting should be done only with rubber float so that the joints are fully filled and compacted.
11.17 In a wide area of installation, the foundation must be divided into areas of 4 X 4 m and 6 X 6 m. Expansion joints of 4 – 6 mm among these areas must be sealed with polyurethane/ non-staining silicone sealants.
11.18 In case floor is exposed to direct sunlight and or temperature exceeding 300C ensure that the surface must be covered with damp cloths for minimum 24 hours.
11.19 Open the surface to pedestrian traffic only after 24 hours of grouting.
11.20 PESL will not assume responsibility or liability for any problems due to improper application.
11.21 It is always advised to consult the adhesive manufacturers for designing the tiling system. Assistance of architectural drawing for tile laying can also be obtained.
11.22 In case of installation of Quantra around stoves, on strongly insolated areas (eg: shop windows), it is necessary to take into account the quality of the substrate concrete and also take into consideration the thermal expansion of the product. Specialised installation technique should be used for laying Quantra Natural Quartz surface on such floors. Please consult the adhesive manufacturers for designing the tiling system for such an application.
11.23 In case of installation of Quantra as a stair component, it is important to take into account the mechanico-physical characteristics of Quantra. The wall junction must enable longitudinal changes of the stair component, i.e. the space on the interface between the wall and the component must be filled with an elastic material, which enables dilatation.
11.24 After Installation see that there is no warpage, defects, deflections etc and check that the:
11.25 visible corners have correct radius and are smooth.
11.26 holes are filled with suitable color.
11.27 joints especially those with front edges are leveled, tight and smooth.
11.28 edges are smooth polished and the color is matched.
15
1 2 . W a l l C l a d d i n g
Quantra can be used for all internal cladding of walls and vertical applications. The installation of vertical panels varies from location to location. When designing and installing vertical panels and cladding, it is necessary to take the mass of the product into account and the services of an experienced structural engineer should be sought during the designing and installation phases.
12.1 We recommend that the following procedure may be followed for cladding Quantra tiles:
12.1.1 Level the wall by plastering.
12.1.2 Before commencing installation check if the wall is of good quality, free from defects, without cracks or splits, free from dust, grease, wax, paint, detaching agents and anything else that could compromise adhesion.
12.1.3 The wall should be made to perfection and sufficiently flat.
12.1.4 The wall plastered surface must be treated with adequate “primers” before applying the adhesive.
12.1.5 Adhesive shall be prepared as instructed by the Adhesive Manufacturer.
12.1.6 After leveling the wall, apply adhesive to the wall and at the back of the tiles with a notched spreader.
12.1.7 You are advised to spread the mix over small surfaces, to be able to fix the tiles within the “open laying time” of the adhesive, i.e. before adhesive forms a sort of skin.
12.1.8 It is important to lay the tiles within the “open laying time” while the adhesive is still fresh.
12.1.9 To ensure contact of the bottom of the tile with adhesive and to adjust thickness, knock gently with a rubber mallet.
12.1.10 For efficient fixing and correct alignment of the tiles, it is recommended to use open and even joints using special plastic tile spacers for such purposes.
12.1.11 Any excess adhesive that bulges out after laying the tiles must be removed immediately using a damp sponge to avoid damaging the finished surface of the tile.
12.1.12 Grouting of the joints should be done after at least 24 hours of fixing of the tile. The joints should be thoroughly cleaned before grouting.
12.1.13 Grouting should be done using a rubber trowel or plastic trowel so that gaps are filled completely, regularly and compactly.
12.1.14 Remove all traces of grout or any other material from the surface of the tiles using a damp sponge.
12.1.15 Mechanical anchors are required for sizes exceeding 600 X 400 mm or weights over 30 kg/m2.
12.1.16 Please consult our Technical Surface Department in case non – standard applications are required.
12.1.17 It is always advised to consult the adhesive manufacturers for designing the cladding system.

14. Inspection
Prior to starting the fabrication, inspect the slab(s) by the following procedure:
14.1 Clean the slabs.
14.2 Check the slabs for any cracks, chips or voids, or any other defects, in a well lighted area.
14.3 Check the colour of the slabs by visual inspection.
14.4 Check the warpage of the slab.
14.5 Check if material available is sufficient.
14.6 Check if all the tools required for fabrication are available.
17
15. Measuring
15.1 Exact measurements are essential for an efficient job and a satisfied customer.
15.2 It is important to remember that shapes to be measured may be straight, angular and/or
circular.
15.3 It is always convenient to keep tape measure, spirit level, square, pencils, rulers, framing
paper, templating material etc., handy.
15.4 The dimensions are calculated by measuring the furniture and adding the dimensions required
for the specific edge or overhang.
15.5 The joints shou
15.6 ld be designed in such a way that they go unnoticed, are symmetrical and use the least amount
of material as possible.
15.7 Measure the width and length of each piece two times to ensure accuracy.
15.8 We recommend leaving a space of 1/4” between the slab and the wall to allow for expansion.
15.9 Do not install slab over any existing backsplash.
15.10 Check the location of the cutouts for faucets, drain pipes etc..and leave a distance between the
cutout and the back edge. Allow some extra space if a backsplash is included.
15.11 All cut outs are to be clearly marked viz., sink cut-outs, electrical, cooktop or slide in range,
etc.
15.12 There is no harm in reverifying the levelness of the cabinets and the “squareness” of the walls.
15.13 Edges need to be clearly noted by type, location and finish.
15.14 Remember that all angles should be conveyed to the drawing.
15.15 Once your measurement is completed you should have all the relevant information on drawing
including the following:
15.15.1 back splashes locations and sizes
15.15.2 countertop dimensions
15.15.3 cutouts dimensions
15.15.4 edge location and sizes
15.15.5 faucet holes location(s) and sizes
15.15.6 interior cabinet dimensions
15.15.7 overhangs location and dimension
15.15.8 material colour
15.15.9 Sink location and model information
15.15.10 Stove location and model information
15.15.11 Seam Location
15.15.12 Windowsill dimension

16. General Guidelines
16.1 Do not change the factory finish of the slab. It is to be utterly avoided.
16.2 To avoid overheating the slab, only water-cooled tools should be used for cutting, drilling, and
polishing.
16.3 To avoid the part from moving, place the anchoring elements near the cutting line.
16.4 First cut, along the longest part of the slab and then the shortest part. Quantra should be cut to
size, shaped and polished with the appropriate diamond tooling using enough water to keep the
surface cool and dust level low. High pressure water jets can also be used for cutting.
16.5 For thick or warped slabs, double cutting technique should be use, i.e., first cutting the material
to half the thickness.
16.6 Every corner must be rounded with a minimum radius of 10mm; by doing this the breakage
possibilities are greatly reduced. Rounding of corners is not necessary on L-shaped counters
where seams fall at corners.
16.7 The cuts should never cross in the corners, as this can cause breakage of the work top in future.
16.8 When cutting an inside corner, always use a core bit to avoid damaging the corner area with
the cutting disc. Damage to the radius area will create a stress point.
16.9 Ensure that all internal corners have a minimum 6mm radius to reduce corner stresses.
Similarly all top and bottom edges of straight-edge profiles should have a minimum of 1.5 mm
radius or should be chamfered.
16.10 Always polish edges with enough water to keep the surface cool and limit dust formation.
Pressure and rotation speed should be kept low. In case the edges are polished without water it
may cause overheating thereby subjecting the edge to chipping or may result in a hairline crack in
the slab. Excessive heat generated due to this would undermine the physical structure of the slab
and may lead to physical and or mechanical damage to the slab.
16.11 The edge is to be polished in a sequence, starting with rough grinding then followed by using
tools or pads with a finer grit until the desired surface finish is achieved. Do not over polish edges
in excess of the factory polish.
16.12 For making holes, the cutting direction should be counter – clockwise.
16.13 Masking tape should be installed where scribing is required.
16.14 A line should be noted which reflects the cutting line.
16.15 Use diamond blades to cut the piece vertically.

1 7 . C o u n t e r T o p I n s t a l l a t i o n
17.1 INSPECTION
17.1.1 Before installing the counter top, cabinet and base units should be checked for the
following:
17.1.2 The cabinets must be plumb, true and flat. Make sure that the level does not vary by a
maximum tolerance of 1.6mm over a length of 3 meters.
17.1.3 The support must be sturdy to eliminate the chance of stone warping or cracking under load
during normal applications.
17.1.4 The support must be able to hold 55-60 kg/m2 plus any additional load that the counter top
could be subject to.
17.1.5 Units should be fastened to both the wall and each other.
17.1.6 Nails, screws or sharp edges should be removed from the surfaces where counter tops are to
be placed.
17.1.7 If the walls are not perfectly square, allowance should be kept prior to cutting.
17.1.8 Air conditioners must be turned off to prevent dust from spreading to other areas.
17.2 INSTALLATION
There are generally two techniques to provide support; full perimeter support and full underlay
support.
17.2.1 Full Perimeter Support
17.2.1.1 The full perimeter support method requires the use of rails with a minimum dimension of
90mm x 18mm positioned at the front and the back of the cabinet.
17.2.1.2 Rails can be made from moisture resistant particle board, moisture resistant MDF,
moisture resistant plywood or timber.
17.2.1.3 Ensure that the cabinet weight is transferred to the floor.
17.2.1.4 Ideal span between supports is 600mm.
17.2.1.5 A gap of 3mm should be kept between edge of the tops and the wall to accommodate any
expansion in the wall or top due to temperature variation in atmosphere.
17.2.1.6 1mm extra gap should be provided per linear meter for counter top lengths exceeding 3
meters.
17.2.1.7 Glue should be applied at regular intervals of 250mm on the back of the counter top.
17.2.1.8 Counter tops should then be placed gently and leveled before the glue cures.
20
17.2.2 Full Underlay Support
17.2.3 The full underlay method involves the placement of a self-supporting panel such as
moisture resistant particleboard, moisture resistant MDF or moisture resistant plywood
under the complete surface area of the quartz surface.
17.2.3.1 For ¾” material a minimum of 3/8” thick plywood sub top should be used.
17.2.3.2 Some types of cabinets may require the use of ¾” plywood for European – style frames
and supports.
17.2.3.3 A minimum clearance of 1/8” (3mm) should be left between plywood and built-up
edges.
17.3 JOINTS
17.3.1 Any cut outs for sink, cook top, etc. should not be placed at a distance less than 15cm
from the joints.
17.3.2 A single counter top with “L” shape or angled section is NOT recommended, as it can
become a potential stress point, and any undue movement in the countertop can lead to
cracking at the stress point. Intersecting pieces in a counter top should be assembled with
two pieces of stone.
17.3.3 All the joints should be well supported underneath.
17.3.4 All the joints should be thoroughly cleaned with acetone or denatured spirit.
17.3.5 For the glue to be well distributed for good adhesion, all the sides of the joints should be
grooved or slotted in the middle.
17.3.6 The flexible glue should be applied for joining the frame to the counter tops.
17.3.7 Masking tape should be used to avoid the glue to move to the polished surface.
17.3.8 Alignment and level along the joints should be checked.
17.3.9 After checking place the clamps at the joints until the adhesive sets properly.
17.3.10 After the joints are set, masking tape can be removed and excess adhesive can be
removed using acetone or denatured spirit.
17.3.11 Mechanical fasteners like screws, nails, etc. should not be used.
17.3.12 Joints above heat generating appliances should be utterly avoided.
17.4 CUT OUTS
17.4.1 Only wet cutting tools should be used for cutting quartz surfaces. Dry cutting tools
should NEVER be used for cutting quartz surfaces.
17.4.2 The internal cut outs must have the largest radius possible to avoid the possibility of
cracking. A minimum of 6mm radius is recommended.
21
17.4.3 In areas above dishwasher and over hot plumbing systems, uneven thermal distribution
over the part of the bench top may occur. To avoid this, it is recommended to thermally
insulate all the hot water plumbing and make the tap holes slightly oversized so that hot
plumbing system is not in direct contact with quartz surface.
17.5 EXPANSION GAPS
17.5.1 To allow for any movements (expansion or contraction) due to variations in ambient
temperature and humidity, expansion gap around the counter top and perimeter walls are
required.
17.5.2 For counter tops of less than 3 meters, 3 to 5 mm expansion gap is recommended for a
normal domestic installation.
17.5.3 For counter tops more than 3 meters a further 1 mm expansion gap is recommended for
every additional meter of counter top.
22
17.6 OVERHANG SUPPORT
17.6.1 Some applications such as a kitchen counter top may require a significant counter top
overhang as a functional element and design feature. The installation guidelines for
residential countertops are shown below:
Depth of Overhang
20 mm (3/4”) Quantra 30 mm
(11/4”)
Recommended support
Less than 300 mm (12”) Less than
400 mm
(16”)
No additional support required
Between 300 – 500 mm (12-20”) Between 400
– 600 mm
(16-24”)
• Brackets required at 600 mm(24”)
intervals
or
• 70mm x 10mm steel flat bar for full
width of the top on a full 18mm thick
plywood, Moisture resistant particle board,
Moisture resistant MDF underlay.
Greater than 500 mm (20”) Greater than
600 mm
(24”)
• Vertical metal leg supports to the
floor is required.
• Brackets should be fastened to a
backer plate, which is secured with the
cabinet with screws.
17.6.2 Wherever overhang depth exceeds 1/3rd of the overall depth of the top, corbels are
required to be used. Corbels are needed to be installed by securing them to wall studs.36”
is the maximum allowable distance between the corbels.
17.6.3 It is suggested to keep position seams over the cabinets rather than in overhangs. Keep
the seams as far from the edges of cabinets as possible.
17.7 SEAM LEVELING
17.7.1 In case that the seam area is not perfectly leveled due to warping, it should be fixed
during the installation process. Using a professional seam setter is one option which is
very economical and commonly used. If this option is not available, a similar result can
be achieved by applying controlled pressure.
23
17.7.2 Two strips of Quantra of size 1.5” x 20” should be clamped with each other using
plywood. This arrangement is used to push both the slabs simultaneously hence allowing
both adjacent pieces of material to have a smoother union by applying controlled
pressure to both side. This is done during the process of fixing the counter top to the
cabinet.
17.8 INSTALLATION OF RETURN SIDE PANEL
In order to avoid cracks in the side/return support of slab, slab should be glued only to the cabinet.
Gluing of slab to cabinet and to both floor (especially in wooden floor which are more prone to
warping and deflection) and walls should be avoided completely. Gluing slab to cabinets, floor and
wall results in restriction of slab from expanding or shrinking freely; hence cause the slab to develop
cracks.
17.9 KITCHEN COUNTER TOPS OVER WOODEN FLOOR
17.9.1 Wooden floor will expand and contract due to temperature and moisture. Installation of
wooden floor over structurally unstable base can cause buckling, gapping or warping.
17.9.2 Quantra counter tops installed over wooden floors are susceptible to develop hairline
fractures and cracks if the installation is not properly carried out. Hence at most care
should be taken while installing Quantra over wooden floor.
17.10 EDGE DETAILS
17.10.1 With Quantra counter tops, numerous edge profiles can be designed. The end application
should be considered while designing the exposed edge profile of a counter top.
17.10.2 The long life and overall performance of the edge of counter top depends directly on the
radius of edge. Larger the radius better is the overall performance of the edge.
17.10.3 It is recommended to avoid designing of sharp edge from the safety point of view and
also to prevent the chipping away of the edges. Square edges are not recommended at
any time.
17.10.4 Always polish Quantra with lots of water. Pneumatic polishing machine is recommended
to avoid electric shock. For under mount sinks, edges need to be finished on all four
sides.
17.10.5 The well rounded edge with 3mm radius profile is considered to be most safe way of
design.
17.10.6 All the edge cuts are recommended to be beveled or chamfered with a minimum of 2 mm
profile at an angle of 45 degree. This will minimize the chances of accidental damage.
17.10.7 In commercial application where high traffic is expected, a minimum of 5 mm pencil
round radius is recommended.
24
17.11 LAMINATION
17.11.1 The thickness of the edges can be increased by laminating two pieces of 20 mm slabs to
get 40 mm edges. There are two main edge construction methods that are employed for
thicker edge.
17.11.2 Before lamination any waves or undulations must be evened out.
17.11.3 Groves and notches must be made on each piece, as Quantra is non–porous it’ll not
absorb the glue applied in the notches.
17.11.4 Material must be thoroughly cleaned with compressed air and acetone before lamination.
17.11.5 For light olours, add extra pigments to the glue to avoid dark seam lines, as more
pigment will prevent glue from changing colour on drying
17.11.6 In lamination method a 20 mm thick slab is bonded to the initial slab. Usually the width
of the slab is 30 mm minimum. The fabricator should use a colour matched adhesive
system but a fine joint line may be visible. It is fabricated with a strip of Quantra (polish
face out) to be attached at the end of front edge. For this also there are two construction
methods:
17.11.6.1 A 45 degree miter between the top and the attached slab edge with a panel underlay
for back support. A minimal joint line at the corner of counter top is visible.
17.11.6.2 An attached slab edge bonded to the underside of the top slab supported by an
underlay back. In this method the line is more visible but however it is more economical
for fabricator.
1 8 . I n s t a l l a t i o n o f B a c k S p l a s h
18.1 Back Splash are used in wet areas, like, behind wash basins / sinks, behind cook tops, etc.
Installer must refer to the building codes and regulations when installing back splash behind gas
cook tops and heat generating appliances. The following guidelines should be considered during
back splash design and installation phase:
18.2 Walls should be clean.
18.3 Walls should be vertical.
18.4 Correct distance should be maintained between back splash surface and a heat generating
source.
18.5 A fiber cement sheet product is recommended for bonding the back splash to the wall. Paper
lined gypsum products are NOT suitable for this application.
18.6 A joint line should be designed between the back splash and counter top for a flexible sealant
(silicone) to fill and seal the gap.
18.7 Back splash pieces should be thoroughly cleaned before installation.
25
18.8 For full height splash backs, verify electrical outlet dimensions and accordingly make holes
for the outlets and leave space for outlet cover.
18.9 A gap of 1/8” between wall and the counter top is preferred; maximum gap could be 3/8”.
18.10 Back Splash should be at least 1” greater in length and cut to fit on site.
18.11 Full height splashes should be flush with the bottom of the upper cabinet trim.
18.12 Back splash should sit on the countertop with 100% silicone being applied.
1 9 . I n s t a l l a t i o n o f S i n k
Following points should be considered during the installation of sink:
19.1 Drop-In Sinks
19.1.1 Kitchen sink faucet should be installed on the underside of the counter top.
19.1.2 For top mount sinks determine the centre of the sink based on the configuration of the
cabinet’s base.
19.1.3 Leave a minimum of at least 1/8” along all the sides of the kitchen sink to allow for
expansion.
19.1.4 There should be a minimum of 2 ½” space from the front of the sink to the tip of Quantra.
19.1.5 Edges should be cleaned with denatured alcohol.
19.1.6 The deck of Quantra should be applied with 100% silicone.
19.1.7 Sink can be dropped in ensuring that it is square with the countertop edge.
19.1.8 In case of sinks, joins may be placed in the cut out area.
19.2 Under mount Sinks
19.2.1 Kitchen sink faucet should be installed on the underside of the counter top.
19.2.2 Build-up should be installed around the perimeter of the sink using plywood or 5/8” MDF.
19.2.3 On the outside of the brackets support strips should be installed from front to back.
19.2.4 The sink and support strips should flush with each other.
19.2.5 The flange of sink should be cleaned with denatured alcohol before colour matched silicone
sealant is applied.
19.2.6 The under mount sinks with pre-drilled holes must have at the back a minimum of 1 ½”
clearance.
19.2.7 The under mount sinks without pre-drilled holes must have the back a minimum of 4 ½”
clearance.
19.2.8 The dimension of hole should be verified, generally it is either 1 ¼ “ or 1 ½”.
19.2.9 The excess silicone sealant is to be removed with denatured alcohol.
19.2.10 The leveling brackets are to be installed.
26
19.2.11 For appliance that will generate heat (cook top), the cut out for the appliance shall be
positioned at least 70 mm from the edge of the countertop. Any butt joint in the counter top
should be at least 150 mm from the cut out for the appliance as heat generated from this
appliance may create the potential for thermal shock.
19.2.12 Also, Butt joints should not be placed above dishwasher. In case it cannot be avoided a full
width substrate of moisture resistant particle board, moisture resistant MDF or moisture
resistant plywood must be located over the dishwasher opening in the cabinets to protect the
joint and Quantra material from heat and movement.
19.3 Sealing Joints
19.3.1 Joint should be exposed by 1/8”.
19.3.2 Epoxy (mixed with hardener) should be applied to the gap between the joints.
19.3.3 Quantra pieces should be jointed together.
19.3.4 Razorblade can be used to check for levelness.
19.3.5 Excess epoxy should be wiped up using a razor blade, rag and lacquer thinner.
19.3.6 Epoxy hardens very quickly so it should be cleaned up immediately after the tops are
confirmed level with the razor blade.
2 0 . E d g e s
20.1 Quantra slabs can be designed with numerous edge profiles. These edges can be designed
using 20mm or 30mm slabs or creating 40mm edges by laminating two pieces of 20mm slabs.
Quantra slabs can be supplied in different edge profiles viz., straight, beveled, chamfered, quarter
bull nose, half bull nose, full bull nose, ogee. More edge details are available on demand.
20.2 It is recommended that the edge should be well rounded one with a minimum of 3mm profiled
radius or more, the larger the radius the better is the life and overall performance of the edge of
the bench top. Designing a sharp edge should be completely avoided both from the safety point of
view and also to prevent the chipping away of edges. We do not recommend square edges.
20.3 Remember to design all visible edges with a minimum of 3mm radius profiles, all the cut
edges should be bevelled or chamfered with a minimum of 2mm profile at an angle of 45 degrees.
This prevents accidental damage to edges.
20.4 Edge polishing needs to be done with enough water to keep the stone cool and limit dust
formation. Pressure and rotation speed should be kept low. The edge is polished stepwise, starting
with rough grinding followed by using tools or pads with a finer grit until the desired finish is
achieved.
20.5 Do not use “buff”pads and never repolish edge in excess of the factory finish.
27
2 1 . C a r e a n d M a i n t e n a n c e
21.1 Quantra is virtually maintenance free and can be cleaned with extreme ease.
21.2 Common household spills – such as, tea, coffee, lemon juice, soda, fruit, vegetable juice, olive
oil or grease spills – are easily removed and the surface can be restored to its original appearance.
21.3 Some Quantra colours and Finishes liked honed, matt, etc., are more sensitive to grease or
finger-prints and may require extra care during routine cleaning.
21.4 Quartz is one of the hardest materials in nature, which is an assurance that your Quantra
surface will not easily scratch or chip. The use of a cutting board is nevertheless recommended.
21.5 To maintain the natural beauty of Quantra, do not place hot skillets or roasting pans directly
onto the surface but use a trivet instead.
21.6 For routine cleaning, use a damp cloth or paper towel and, if necessary, a small amount of mild
soap. Once clean, rinse and dry the surface thoroughly.
21.7 For stubborn or dried spills, use a nonabrasive cleaning pad such as a white 3M Scotch-Brite®
scrub pad combined with a small amount of mild soap or specialized stone cleaner.
21.8 Quantra floors in high traffic areas should be cleaned daily with a clean, dry dust mop or soft
bristle broom. Quantra floors in low traffic areas can be cleaned less frequently using the same
method. Spills should be spot treated with the use of a damp mop or cloth towel and, if necessary,
a small amount of mild soap or specialized stone cleaner.
21.9 A floor machine such as a slow speed buffer or walk behind scrubber can be used for larger
commercial environments. Be sure to rinse thoroughly to remove any haze residue that may
diminish the shine and beauty of the floor.
21.10 For heavily soiled floors, as with any floor, it makes sense to clean up spills as soon as
possible. .
21.11 Avoid exposing Quantra to chemicals and solvents, especially paint removers or furniture
strippers containing trichlorethane or methylene chloride. Keep away nail polish remover, bleach
or cleansers that contain bleach, bluing, permanent markers or inks,. While casual exposure to
alkaline materials will not damage Quantra, but highly alkaline (high-pH) cleansers are not
recommended when cleaning Quantra. If any of the substances listed above come into contact
with Quantra, rinse the exposed surface immediately and thoroughly with plenty of clean water.
21.12 Do not use strong abrasive and/or alkaline cleaning products. Always follow the
manufacturers' dilution instructions and recommendations.
28
2 2 . S t o r a g e , H a n d l i n g a n d T r a n s p o r t a t i o n
While storing and handling Quantra please ensure that the following are fully complied with:
22.1 Slabs should be stored vertically on a 150 angle with support at stop and bottom of the steel
“A” frame.
22.2 Slabs must always be stored in a way that the polished surface is not exposed to the sun. It is
not necessary to store the slabs in a shaded area, but it is necessary to keep the last slab in each
rack in a position in which the backside is facing out.
22.3 There should be no more than 20 slabs to each rack with the slabs face-to-face and back-to-
back. Make sure the face is always protected and not touching the metal or the back of another
slab, etc. Polished edges should be covered using blankets, carpet or any other type of quality
padding for protection.
22.4 Storage temperatures should not exceed 129°F. Tarpaulins can be used to cover slabs stored
under direct sunlight.
22.5 All racking should have a protective layer between the rack and the slabs. This will help to
prevent scratching or other surface damage during storage or transit.
22.6 While transporting Quantra please ensure that the following are fully complied with:
22.7 Do not transport slabs horizontally and use proper “A” frames. The horizontal storage can put
stress on the material and cause the material to break.
22.8 When suction cups or grips are being used, slab should be held low to the ground. Cut-out
pieces should be braced to avoid flexing and should be placed at the top of the A-Frame to
prevent bearing the load. Similarly laminated edges should be top loaded to avoid bearing the
load.
22.9 The slabs should be strapped onto A-Frames to prevent flexing. Care should be taken to protect
the straps from being damaged or cut by the edge of the slab.
22.10 Carts and dollies should be used when transporting Slab around the shop.
22.11 Preferred unloading route is using a forklift or other lifting device capable of handling the
appropriate capacity without any body part being between it and the ground.
22.12 Gloves, Safety Shoes and Glass should be worn while handling Quantra.
29
2 3 . P a c k i n g
23.1 Quantra products are carefully packed and loaded for shipment using all reasonable and
customary precautions against damage in transit.
23.2 The slabs are put polished side by polished side on wooden or metallic stands. The slabs are
wrapped in a plastic. The slabs are uniformly in the stands in order to avoid any movement in the
stands.
23.3 Tiles are packed into cardboard boxes and loaded into the crates or on pallets. The tiles are put
polished side by polished side in order to prevent scratches. In order to prevent movement of the
tiles on the pallets or in boxes, wooden, paper filling and strips are used. If the strip is metallic,
there is plastic protecting element unit between the strip and tiles in order to prevent scratching or
contamination by rust. The product is laid uniformly on the pallets and does not overhang. The
product packed on pallets is protected against atmospheric influence with shrinkable plastic wrap.
Each box and pallet is marked properly with a label.
