FLOOR FINISHES
Floors are both functional and decorative and play an important part in the cleaning and
maintenance program of any hotel. They cover a large area and are subjected to a great
deal of wear and tear. Clean and well-kept floors indicate the standard of cleanliness
throughout the establishment.
SELECTION CRITERIA FOR CHOOSING FLOOR FINISHES: -
Appearance – color, design, cold, warmth, comfort
Resistance to spills – water, grease, food, acid, etc.
Safety
Life expectancy
Durability
Ease of cleaning in relation to the type and amount of soiling
Sound and heat insulation
Cost
Nature and condition of sub floor(layer below the floor finishes made of concrete or
wood)
Hard floors are usually sealed to give a non-absorbent, semi permanent gloss or finish
which will wear off in time. Seal is applied on clean and dry floor. Before re-sealing any
remaining seal has to be striped off. This is done with a chemical stripper, except in the
case of wood and cork where sanding is done.
In order to preserve the seal, polish should be applied to sealed flooring. Polishes are
usually spirit or water based. Spirit based floor polishes may be paste or liquid and
require buffing when dry to produce a shine. Water based polishes are liquid and dries
after application to give a shiny surface.
SUBFLOORS
In large modern buildings the sub floor is often made of concrete, but in older and
smaller buildings it consists of soft wooden boards, nailed to wooden joints.
Suspended Timber Floors: Tongued and groove or butted boards are supported by timber
joists in this type of base floor. As floor boards move a little when they are walked upon,
the choice of floor covering is limited to those types of that are not affected by movement
or ‘give’. A modern development in suspended floor construction is the use of large
sheets of materials such as plywood or flooring-grade chipboard in place of wood
baseboards.
Solid Concrete Floors: Concrete is laid directly onto the hard core and earth at the
ground level of all modern buildings. Pre-cast concrete slabs are used for the intermediate
floors. Concrete floors are given a cement screed layer on top to smooth out the
roughness and provide a flat surface on which flooring material can be laid. Concrete
floors provide a very stable floor.
2
TYPES OF FLOOR FINISHES:-
1) HARD
Non Resilient (does not get bend or dented) eg.(Marble, granite, terrazzo, concrete)
Resilient (Wood, Asphalt, Bitumastic)
2) SEMI-HARD (Cork, rubber, linoleum)
3) SOFT (Carpets, rugs etc.)
HARD FINISHES
Hard floorings are durable but noisy, with the exception of some wood flooring. Hard
floorings are mostly cold in feel, vermin-proof, impervious to dry rot, fire-retardant, and
easily cleaned. Hard floorings can be further classified as non-resilient and resilient
floorings. The term resilient means bounce back capacity.
Non-Resilient Hard Floor Finishes:
1) STONE: This is a good choice of flooring for a natural appearance and an almost
indefinite life. All types of stone are very heavy and must be laid on a solid concrete sub-
floor. Stone floors are resistant to wear, water, indentation, and to most cleaning
chemicals. The various types of stone commonly used are:
a) Marble: - This is the best known of all stone floorings and is available in a wide range
of patterns and colours including white, grey, pink, green, brown and black. Marble is
crystallized limestone. It may have a banded (serpentine) pattern or may be mottled.
Marble is durable, but lighter colours yellow with age. Honed marble is recommended for
commercial floors. It gives a satin finish with little or no gloss. Sandblasted or abrasive-
finished marbles marble has a matte effect and is suitable for exterior use. Travertine
marble is cheaper and is characterized by small cavities on the surface, which offer
greater slip resistance and allows dust to settle. Marble stains easily on coming in contact
with ferrous metals and oils. Marble is available in tiles ranging in size from 12 inches up
to 18 inches square, but slabs up to 5x3 ft can be obtained on special order. Marble is
very expensive. Mainly used for lobbies, rooms, stairways etc.
SERPENTINE PATTERN MOTTLED PATTERN HONED MARBLE
SANDBLASTED MARBLE TRAVERTINE MARBLE

b) Slate: This is a hard, impervious stone that may be given a polished, sawn or riven
surface. Riven slate is split along its natural layers, so that the natural undulations give it
a rippled surface that is less slippery when wet than a smooth surface would be. The
natural colours of slate are blue grey and grey. Slate forms when layers of mud and silt
build up and solidify over millions of years. For interior use, slate slabs come in standard
sizes of 18x19 inches, but larger slabs up to 6.5 ft or 6 x 3 ft are also available.
SAWN SLATE RIVEN SLATE
c) Quartzite: This is a crystallized rock with a matte finish. Embedded quartz grains give
it a slight sparkle. Its colour range from silver grey to olive, yellow and gold. They are
very hard wearing, non-slip, and suitable for both interiors and exteriors. The thickness of
the quartzite slab depends on the rock formation.
QUARTZITE FLOORING
d) Sandstone, limestone and granite: Sandstone is a sedimentary rock composed of
compressed sand. Limestone is composed of calcium carbonate. Granite is a granular
crystalline rock of quartz, feldspar and mica. All three stones make good flooring
material. Colours include various shades of grey, beige, green and brown. Mainly used
for vanitory counter, table tops etc.
SANDSTONE FLOORING LIMESTONE FLOORING GRANITE FLOORING
2) CONCRETE: This material is good for areas that take hard wear, as it is highly
resistant to chipping and cracking, scratching, indentation, heat. Most types of concrete
are used for exteriors such as patios, but concrete tiles and terrazzo are suitable for indoor
use. Concrete floors are found in heavy traffic areas like equipment areas. Properties
often have concrete floors in parking areas, garages and exhibition areas. Concrete is a
mixture of cement and various fillers such as sand, gravel, crushed stones and sea shells.
The elements are mixed in dry form and then combined with water, reacting chemically
to form the hard, stone-like material. The curing or hardening of concrete is a hydration
4
process. Concrete floorings are easy to clean but should not be polished as they can be
slippery.
a) Granolithic Concrete: This is plain concrete structural flooring on which a surface of
granite chippings and cement is cast on site. The final surface is hard wearing and its
appearance is improved if the surface is polished to expose the aggregate in the concrete.
It is used for basement corridors, storerooms, stairways and laundry. It is usually laid in
tile form.
GRANOLITHIC CONCRETE
b) Concrete Flags: This low cost flooring is used for terraces and garden paths. A variety
of colours, sizes, and shapes is available. Concrete paving stones are available with a
finish that imitates the texture of natural stone. They should be laid on sand or a bed of
weak-mix concrete, the surface of which is well leveled.
CONCRETE FLAGS
c) Concrete Tiles: These are made of coloured cement and hard wearing aggregate
surfaces applied to a concrete backing. They have a good wearing property and are
available in sizes from 4 sq inches to 18 sq. inches.
CONCRETE TILES
d) Terrazzo:-Is flooring that can be cast on site to form panels of up to 1 sq. metre or can
be pressed into tiles off-site. The appearance of terrazzo depends upon the aggregate
chippings used. The chippings may be made of marble, pebbles, stones set in a matrix or
mortar of cement. It is then machine grounded to make a smooth surface. The matrix is
5
often referred to as grout. Like most porous surfaces, terrazzo floors must be sealed for
durability. Terrazzo is used in foyers, cloakrooms and kitchens.
TERRAZZO FLOORING
3) VITREOUS / CERAMIC FLOORINGS: This refers to flooring material that have
been made of some clay product and fired in a kiln to produce a hard, stone-like quality.
Ceramic flooring is the most common name for this type of material. Vitreous materials
are mostly composed of silicon materials that flow together and bond during the firing
process to form a glass like ceramic. Combination of clay, marble, slate, glass and flint
are used to make ceramic tiles. Ceramics are resistant to chipping, scratching, and
indentation but offer a long lasting, hard wearing floor that is easy to clean. It can be
classified into glazed and unglazed ceramic ex, quarry tiles, bricks, glazed tiles, paver
stones.
a) Glazed Ceramic Tiles/ Clay Floor Tiles: These are made from refined natural clays
fired at high temperatures and glazed. They are available in a variety of sizes, shapes,
textures, colours, and patterns. Ceramic tiles require a solid sub-floor and can be laid
either directly on concrete by bedding them in the cement or may be fixed to the screed
with adhesive. They are used in luxurious bathrooms and patios. Tessellated tiles are
small ceramic tiles, often used in mosaics that give a highly decorative floor. These tiles
may also crack or break under heavy weights or impact.
GLAZED CERAMIC TILES TESSELLATED TILES
b) Quarry Tiles: These are hard wearing tiles made from blend of unrefined clays hard
burnt under pressure to make them durable. Harder tiles are less absorbent, but more
slippery. They are available in heather brown, red and blue colours. They can be laid
directly on concrete by bedding in cement. It is used in cloakrooms, kitchens, canteens.
The standard size is 6 square inches of 15 mm thickness. Larger sizes, such as 8 sq.
inches, are also made.

QUARRY TILES
c) Mosaic: There are three types of mosaic tiles: clay, glass and marble. They are made in
small squares and other shapes that can be assembled into larger patterns. Fully vitrified
mosaic tiles are made especially for outdoor use. Ideally, mosaic tiles need a solid sub-
floor, but they can be laid on a suspended floor over a small area, such as in a shower
enclosure.
MOSAIC TILES
d) Brick: These are different from terracotta tiles only in thickness and shape, the material
is the same. Bricks are usually not glazed and are very porous. They are generally 3
inches x 6 inches in size.
BRICK FLOORING
e) Terracotta Tiles: These are unglazed, hard baked tiles made from hand formed clay
available in smoky red to sun-baked orange colours. They are porous and need to be
sealed with a linseed oil sealant and waxed for added protection. Overtime, terracotta
tiles may crack or chip.
7
TERRACOTTA TILES
f) Pavers: These are tiles that resemble natural quarry tiles. They are produced by
compression and are available in different colours. They are often 12 sq inches in size
and are used in driveways.
PAVERS
4) MAGNESITE / OXYCHLORIDE: A flooring material composed of magnesium
chloride, using magnesium oxide as a binder, sawdust, ground silica, and fine powdered
wood waste; used as a finishing surface on concrete floor slabs This finish is extremely
porous and washing should be avoided as much as possible. It maybe sealed and /or
polished to prevent the penetration of water and dirt, but then it becomes very slippery.
These floors are used in areas where no water is used like linen rooms.
MAGNESITE FLOORING
5) RESIN FLOORINGS: These are composed of synthetic resins usually epoxy,
polyester, polyurethane with different hardeners. Vinyl or marble chips may be included
to give a more decorative flooring resembling terrazzo. They are non-skid and suitable
for use in kitchens, canteens, bathrooms, corridors and laundries. They provide excellent
wear.

RESIN FLOORING
Resilient Hard Floor Finishes
1) WOOD: This is the oldest material used. Soft woods such as pine and fir have a high
degree of resilience, whereas hardwoods such as oak and maple have low resilience.
Hardwood is obtained from broad-leafed trees such as oak, teak, maple, walnut, birch,
beech and so on. Commonly used soft woods are pine, fir, cedar, rubber wood. The
durability of wood flooring depends on good maintenance and on the quality of wood.
Hard woods are resistant to abrasion and indentation, but they should not be used in wet
areas. Wood floors are warm to the touch and tend to be noisy. They are not slippery
unless too much polish is used. The biggest disadvantage of wood floors is their porosity,
absorbency and susceptibility to damage by water. To prevent absorption of spills and
dirt, wood flooring should be sealed and or polished. Wood floorings are poor conductor
of heat, and so are good insulators. Wood floors being resilient are less tiring to walk on
than non-resilient surfaces. Wood is however, inflammable, susceptible to dry-rot, and
scratches and splinters with the dragging of heavy articles across it. Some types of wood
finishes are outlined below:
a) Wood Parquet: A high quality hardwood flooring in which decorative hardwoods are
cut into blocks and formed into panels, permitting elaborate geometric patterns such as
herringbones, basket weaves, and strips. The panels vary from 1 inch to 1¼ inches in
thickness; sizes vary from 12 sq inches to 2 sq. ft. Parquet may be laid over any rigid
wooden sub-floor. It is used rarely nowadays because of its high cost. It is used in foyers
and lounges in conjunction with rugs.
HERRINGBONE WOOD PARQUET BASKET WOOD PARQUET

STRIP WOOD PARQUET
b) Plywood: These are made into tiles that can be used to simulate wood parquet, but are
generally called ‘parquet’ these days even when laid simply to resemble a board floor. Plywood parquet tiles are not durable in areas of heavy wear. It is supplied in various
squares from 9 inches to 3 ft.
PLYWOOD FLOORING
c) Hardwood Strip and Block: These are high quality wood floorings made of hardwoods.
It improves with age. Hardwood blocks vary in thickness from ¾ inch to 1¼ inch and the
size may be upto 12 x 3 inches. The strips used are upto 4 inches wide, and are carved to
have a tongue and groove. It must be laid on a dry, solid sub-floor and held in place with
cold bituminous adhesives.
HARDWOOD BLOCK
d) Wood Mosaic: Hardwood ‘fingers’ arranged in a basket weave pattern are stuck to a sheet of backing material to form panels 18 inches square and ⅜ inch thick. Wood mosaic
has very good wearing characteristics.

WOOD MOSAIC
2) ASPHALT TILES: These are a close relative of linoleum because of the asphalt used
in their construction. They are composed of asbestos fibers, pigments, and inert fillers
bound with asphalt in the case of the darker varieties and with some other resinous binder
in the case of lighter colours.
ASPHALT TILES
3) BITUMASTIC FLOORING: This is a joint less, low-cost flooring and consists of a
type of asphalt rolled onto a solid sub floor in a hot plastic state. It is soft in texture and
impermeable to water. It is normally black, red or brown in colour used in public
restrooms, hospital corridors, and other heavy traffic areas. It is damaged by heat and
heavy weights and is also harmed by spirits, oils and acids.
BITUMASTIC FLOORING
SEMI-HARD FINISHES
Semi-hard or smooth floor finishes are durable, but normally less permanent than hard
floor finishes. They are all resilient, except thermoplastic tiles. These floorings are
resistant to pests as well as are easy to clean.
1) LINOLEUM: This is made from oxidized linseed oil or a combination of drying oils,
wood flour, ground cork, resins and pigments. This compound is mixed and pressed onto
an asphalt soaked piece of felt which is heated to bond the elements. It is affected by high
temperatures and strong alkalis. Gets dented, scratched easily. It is absorbent thus
11
minimum amount of water should be used. It is used in linen rooms, corridors, bathrooms
and canteens.
LINOLEUM FLOORING
2) CORK: Obtained from the outer, light brown bark of cork oak trees, cork is ground
into large granules, mixed with synthetic resin, pressed into sheets at high temperature
and pressure, and then cut into strips of varying widths. It has a warm and restful
appearance. They have excellent acoustic properties. It is extremely porous, dents, burns,
and stains easily. The different varieties are untreated cork tiles, cork tiles with PVC
surface.
CORK FLOORING
3) RUBBER: This type of flooring is made from synthetic rubber. A filler or clay is
often used. Rubber maintains a good luster without any finishing treatments, and has a
good resistance to chemical and surface moisture. It is harmed by spirit, grease, sunlight,
alkalis. It is used in entrance halls, canteens and places where noise should be kept to
minimum.
RUBBER FLOORING
4) PLASTIC FLOORING: A wide range of colours, designs, textures and prices makes
plastic flooring very versatile. Those plastic floors which have a high PVC content in the
surface, such as flexible PVC tiles and sheets or PVC with various backings, are very
hard wearing. All types are resistant to wear, water, indentation, and to most cleaning
chemicals. The different types of plastic floorings are:
a) Thermoplastic and vinylized thermoplastic tiles: These are made from a variety of
asphalt binders with inert fillers and pigments. They are rigid tiles, set closely as possible
12
with adhesive. They are laid down in a thermoplastic state, but harden on cooling and
may be carried up the wall to form a small coved skirting. These floorings are non-porous
but hard and noisy. These are used in bathrooms, corridors and offices.
VINYLIZED THERMOPLASTIC VINYL ASBESTOS TILES
They are available in two main types.
Vinyl asbestos, which is obtained only in tile form, is manufactured from PVC or similar
synthetic resins, fillers including short fiber asbestos, and pigments. It is available in wide
range of colours and the tiles can be stuck to a solid sub floor with a suitable adhesive.
Flexible form of Vinyl is based on PVC or similar synthetic resins, fillers, pigments and
plasticizers. These do not get cracked and are hard. Both types maybe used in bathrooms,
cloakrooms, canteens, offices, etc.
SOFT FLOOR COVERINGS
These are resilient floorings and include all types of carpets, rugs, and mats. Soft
floorings are quiet, warm and slip-resistant. They are available in variety of colours,
textures and patterns.
1) CARPETS: These typically consist of a backing or foundation and a surface pile,
which may be cut or uncut. The backing may be jute or cotton; linen and hemp are also
used. The pile yarn may be of wool, cotton, nylon, polyester etc. They are used because
of their attractive appearance, safety factor, warmth and sound insulation.
2) MATS & RUGS: These may be constructed from textile fibres or harder materials.
PROTECTIVE METHODS ON HARD FLOORINGS:-
A) SEAL –Seals are semi permanent finish applied on floors which gives a non-
absorbent, gloss. Seal is applied on clean and dry floor. Before re-sealing any remaining
13
seal has to be striped off. This is done with a chemical stripper, except in the case of
wood and cork where sanding is done.
B) POLISH-In order to preserve the seal, polish should be applied to sealed flooring.
Polishes are usually spirit or water based. Spirit based floor polishes may be paste or
liquid and require buffing when dry to produce a shine. Water based polishes are liquid
and dries after application to give a shiny surface.
