Colours

Exclusive colour designing is possible within the colour shades of our FloorColor collection,additionally - as special colour.

Note: Due to the addition of conductive carbon fibres, adverse visual effects may occur, particularlywhen special colours are used.

In UV stressed areas the material may show a yellowing effect, but the technical properties will not beaffected.Discolouration and chalking effects may occur with weathering and UV light exposure. The colourants/organic dyestuffs in e.g. coffee, red wine or leaves and various chemicals, e.g. disinfectants, acids,etc., may cause discolouration. Proper functioning of the coating will not be affected by these changes.

Application

Concrete, cement screed and hard asphalt screed in interiors.

The substrate must be dry, sound, dimensionally stable, solid and free from all substances that mayprevent good adhesion, e.g. loose/brittle materials, dust, oils, fats/greases or rubber abrasion(skidmarks). Cementitious flow mortars, upgraded with synthetics, must be checked for compatibilityby coating a test area on site, if necessary.

The average value for adhesive tensile strength must be 1.5 N/mm², with a single/individual minimumvalue of 1.0 N/mm². Substrates must have achieved their equilibrium moisture content (EMC):Concrete and cement screed: max. 4 % by weight (CM method).Testing method for the above mentioned values as per DAfStb, repair guideline part 3.

If rising damp (moisture on the reverse side of the coating) cannot be excluded, then it is essential toapply a pore-free priming coat of Disboxid 420 E.MI Primer or Disboxid 462 EP-Siegel Neu.Therefore the average value for adhesive tensile strength must be 2.0 N/mm², with a single minimumvalue of 1.5 N/mm².

Hard asphalt screed must match hardness level IC 10 or IC 15 and must not deform under theprevailing circumstances (temperatures and mechanical loads) on site.

Other types of substrates or proceedings require a special advisory service by Disbon.

Suitable Substrates

Technical Information No. 429

Prepare the existing substrate very thoroughly by shot-blasting with solid shot/grit (shot peening),avoiding dust due to simultaneous suction cleaning.The degree of removing layers of lower adherence is depending on pressure, type and amount ofshotblasting medium.Grinding is only permissible for small (border) areas, except for the preparation using diamond grindingtechnique to remove layers of lower adherence.Germany: Follow BEB-Arbeitsblatt (process sheet) KH-0/U* and BEB-Arbeitsblatt KH 3*, as well asTable 2.5 of the Guideline "Richtline Schutz und Instandsetzung von Betonbauteilen, Teil 2 des "Deutschen Ausschuß für Stahlbeton" / Protection & Repair of concrete elements, part 2 of "GermanCommittee for reinforced concrete".Thoroughly clean existing, rigid/stiff 2-component coatings and roughen/flatten them by grinding orblasting to remove all remaining substances, care products and the like from the surface to be coated.Repair spallings and defects with Disbocret® PCC or Disboxid EP mortars, filling them flush with thesurface.

Thoroughly prepared hard asphalt screed: The aggregate must be visible for min. 75 %.

All material with silicone content cannot be used in the surrounding area (ambiance) before and duringwork, in order to avoid surface troubles (loss of adhesion).

Surface Coating System

Note: Priming coat and scratch filler coat are not to be quartz sand-treated (scattered), but must becoated with the conductive coat within 24 hours at 20 °C. Intermediate grinding is necessary, if thewaiting time is extended.

Technical Information No. 429

Laying the earthing/grounding connectionsAllow the priming coat to harden, then stick self-adhesive copper strips Disbon 973 (length: approx. 50cm) circulating the wall area (see figure) in a distance of max. 20 m. A minimum of two earthconnections is required. The Disboxid 975 Leitset (conductive set) contains the necessary contactpoints for the earth/ground potential, that can be integrated within the coating system. Surfaces thatare separated by joints are to be separately grounded. A maximum distance of < 20 m between copperstrips must be respected for large connected surfaces, by applying additional earth connections topylons or other mounting parts.Clean the thoroughly applied copper strips with a cloth, wetted with thinner Disboxid 419. The copperstrips must be connected by an expert for electrical supply with the earthing/grounding of the buildingafter having finished the coating operations.

Layout for Earthing Connections:

1. Disbon 973 Kupferband (copper strip)2. Braided (litz) wire made of copper, 4 mm² for connection to the earthing/grounding (ring line).

Conductive Intermediate CoatRoller apply one conductive coat of Disboxid 471 AS-Grund or Disboxid 5022 WHG-Leitschicht to thepriming coat. Allow to harden and check for antistatic discharge capability before applying the finishing(top) coat. Der Resistance to earth must not exceed 5 x 104 ohm. Otherwise additionally earthing/grounding connections must be applied.Consumption*:Disboxid 471 AS-Grund: approx. 100 g/m² orDisboxid 5022 WHG-Leitschicht: approx. 120 g/m²

Note: Provide for good ventilation during drying and hardening phase/period.

Finishing (Top) CoatConductive flow coat (self-levelling):Pour Disbothan 429 PU-Decksiegel AS to the floor space and spread evenly with a notched wiper/squeegee (triangular notching, 4 mm)**. Then draw on the freshly applied coating with the reverse sideof the tool. Leave to stand for about 10 minutes and then remove blistering with a spiked roller to alignthe carbon fibres.Consumption*:Disbothan 429 PU-Decksiegel AS: approx. 2.5 kg/m² (approx. 1.5 mm of layer/coating thickness)

Note: Consumption must not exceed a max. of 3.0 kg/m², otherwise the conductive capability cannotbe guaranteed. Disbothan 429 PU-Decksiegel AS must not be filled with quartz sand (exception:scratch filler coat). The finishing (top) coat must be applied in one operation. For repairs or revisions aconductive intermediate coat of Disboxid 471 AS-Grund or Disboxid 5022 WHG-Leitschicht (earthing/grounding incl.) is essential. 

* Determine the exact amount of material required by coating a test area on site.** Guide value. Notching always depends on the wear resistance of squeegee, as well as temperature,degree of filling and substrate conditions on site.
