Discolouration and chalking effects may occur with weathering and UV light exposure. The pigmentation in, e.g. coffee, red wine or leaves (organic dyestuffs) and various chemicals, e.g. disinfectants, acids, etc., may cause discolouration. Proper functioning of the coating will not be affected by these changes.

approx. 90 sSuitable Substrates
All types of mineral substrates.
The substrates must be sound, dimensionally stable, solid and free from all materials that may prevent good adhesion, e.g. loose/brittle materials, dust, oils, fats/greases or abraded rubber contamination (scuff/skid marks). Cementitious flow mortars, ameliorated with synthetic resin, must be checked for compatibility by trial application, if necessary. The adhesive tensile (pull-off) strength of substrates must be 1.5 N/mm2 on an average, with a minimum individual value of 1.0 N/mm2.
Substrates must have achieved their equilibrium moisture content:
Concrete and cement-based composition floor (screed): max. 4 % by weight
Anhydrite screed: max. 1 % by weight
Magnesite screed: 2–4 % by weight
Xylolithe (Magnesium Oxychloride) screed: 4–8 % by weight
Substrate Preparation
Prepare the substrate by suitable means, e.g. grit blasting (shot peening) or milling, in order to meet the above mentioned requirements. Always remove existing 1-component coatings and loose 2-component coatings.Vitreous surfaces and surfaces of rigid existing 2-component coatings must be cleaned and roughened (flattened) by sanding or blasting or should be primed with Disbon 481 EP-Uniprimer. Repair spallings and defects with Disbocret® PCC or Disboxid EP mortars and fillers, filling them flush with the surface.
Preparation of Material
Add the hardener to the base material and stir intensively with a low-speed electric paddle (agitator; max. 400 rpm). Pour the mixture into another clean container and continue stirring.Mixing Ratio
Base : hardener = 4 : 1 parts by weightMethod of Application
Apply the material with a notched hard rubber float/wiper (2 mm notching) and then treat crosswise with a texturing roller.Surface Coating System
Priming Coat
Mineral substrates:
Prime with epoxy impregnation Disbopox 443 EP-Imprägnierung. Rough surfaces need an additional scratch filler application.
Level semi-rough surfaces with:
Disbopox 468 EP-Strukturschicht: 100 % by weight
Disboxid 942 Mischquarz: 20 % by weight
Level uneven, rough-textured substrates with:
Disbopox 453 Verlaufschicht: 100 % by weight
Disboxid 942 Mischquarz: max. 20% by weight
Existing rigid substrates:
Treat the surfaces according to the point "Substrate Preparation”.
Laying the Earth/Grounding Connections:
Allow the priming coat to harden, then stick self-adhesive copper strips Disbon 973 (length: approx. 50 cm) circulating the wall area (see figure) in a distance of max. 20 m. A minimum of two earth connections is required. The Disboxid 975 Leitset (conductive set) contains the necessary contact points for the earth/ground potential, that can be integrated within the coating system. Surfaces that are separated by joints are to be separately grounded. A maximum distance of ≤ 20 m between copper strips must be respected in case of large connected surfaces, by applying additional earth connections to pylons or other mounting parts.
Clean the thoroughly applied copper strips with a cloth, wetted with thinner Disboxid 419. The copper strips must be connected (by an expert for electrical supply) with the earthing/grounding of the building after having finished the application of coatings. Due to the low layer thickness, the copper band may emerge in the surface. Therefore, the copper band has to be installed in mechanically protected areas.
Layout for earthing connections:

| Disbon 973 Kupferband Braided wire made of copper, 4 mm2 for connection to the earthing/grounding (ring line) |
Textured Coating
Apply Disbopox 971 ESD Roller Coating with a notched hard rubber float/wiper. Then rework crosswise with a medium-porous Moltoprene roller (approx. 2 mm diameter of pores). Therefore the freshly coated surface is walkable with special hobnailed boots. During application the roller should be rolled from time to time on a neutral substrate to become dry and should be replaced for the work on large surfaces after approx. 100 m2 of usage.
Consumption
| Priming Coat | approx. 200 g/m2 |
| Priming Coat Semi-rough substrates: | |
| Disbopox 468 EP-Strukturschicht | approx. 1.3 kg/mm/m2 |
| Disboxid 942 Mischquarz | approx. 260 g/mm/m2 |
| Uneven, rough-textured substrates: | |
| Disbopox 453 Verlaufschicht | approx. 1.04–1.2 kg/mm/m2 |
| Disboxid 942 Mischquarz | approx. 210–240 g/mm/m2 |
| Finishing Coat | approx. 400 g/m2 |
✱ The exact rate of consumption is best established by a trial coating.
Workability
At 20 °C and 60 % relative humidity approx. 60 minutes.
Higher temperatures shorten and lower temperatures extend the pot life.
Application Conditions
Material, atmospheric, and substrate temperature:Min. 12 °C, max. 30 °C during application and drying.
Relative humidity must not exceed 80 %. Substrate temperature should always be min. 3 °C above the dew point temperature.
Waiting Time
at 20°C the minimum waiting time between coatings should be between min. 16 hours and max. 24 hours. After extended waiting periods, the surface must be roughened and primed again. Higher temperatures shorten and lower temperatures extend the waiting time.Drying/Drying Time
At 20 °C and 60 % relative humidity, walkable after approx. 24 hours, ready for mechanical loads after approx. 3 days and completely hardened after 7 days. Lower temperatures extend the drying time. During the curing process (approx. 16 hours at 20 °C), the applied coat should be protected against moisture, as it may lead to surface faults and loss of adhesion.
Tool Cleaning
Immediately after use or during longer breaks with water or warm soapy water.
