The topping shall be capable of accepting foot traffic at 24 hours and vehicular traffic at 48 hours. Application Instructions Surface preparation Durafloor V Anti-Skid can be applied to a variety of substrates. As with all flooring materials or protective coatings, correct surface preparation is essential. Steel substrates: Durafloor V Anti-Skid is specially formulated to exhibit tenacious adhesion to unprimed steel. However, all steel substrates should be blast cleaned to a minimum Sa 2 1/2 standard of cleanliness. An angular profile amptitude of at least 75 microns is recommended. The slurry should be applied as quickly as possible to the blasted steel surface. If the standard of the surface falls below Sa 2 1/2 then the steel must be reblasted. Concrete substrates: Durafloor V Anti-Skid is applied to clean, sound, dry concrete substrates which are free of any laitance, or loose particles. Mechanical scarifying or blasting methods are strongly recommended. Prepared concrete substrates should be primed with Nitomortar 903, applied by lambswool roller to provide a thin even coverage. Avoid over application and puddles. Durafloor V Anti-Skid is applied onto the Nitomortar 903 whilst still wet/tacky. Asphalt surfaces: Durafloor V Anti-Skid can be applied onto asphalt substrates providing they are clean, sound and dry. It is also recommended that the asphalt should be at least 3 months old. The asphalt should be lightly grit blasted to remove any weakly bonded or contaminated material to provide the desired surface. No primer is required on asphalt. Wooden substrates: Durafloor V Anti-Skid can be applied directly onto clean, dry timber substrates. Aluminium substrates: Must be sweepblasted, and degreased using Solvent 10 to provide a sound mechanical key. Durafloor V Anti-Skid can be applied directly to the prepared substrate. Mixing Mix the two liquid components (A & B) thoroughly using a forced action mixer such as a cretangle. Add the mineral fillers and mix until a homogenous slurry consistency is formed. The total mixing operation should take about 5 - 7 minutes. The Durafloor V Anti-Skid is now ready to use. Do not add thinners or solvent. Durafloor V Anti-Skid Thickener can be mixed at this stage if material is going to be used on ramped surfaces to prevent material slumping. Laying Once mixed the Durafloor V Anti-Skid must be used within the specified pot life. Pour the slurry onto the prepared surface. Work in lanes of 2 - 3 m width, masking off edges with tape. Spread the slurry using a steel trowel or squeegee taking particular care when joining up to previous days work. Use of a wet film gauge is recommended to ensure the correct thickness and material usage. Durafloor Heavy Duty Aggregate must be applied immediately after laying Durafloor V Anti-Skid. The slurry coating is blinded to saturation by allowing the aggregate to fall vertically until no slurry is visible. Do not throw aggregate across the slurry as this may cause ridges. Masking tape must be removed before the coating has cured. The Durafloor V Anti-Skid must be allowed to cure for 24 hours at 20oC before being subject to foot traffic. At lower temperatures this period will be increased. Providing it is clean and dry, excess dressing aggregate can be removed and reused after the initial curing period. Durafloor V Anti Skid Thickener can be added to the slurry prior to laying to help prevent the material slumping on ramped areas. Cleaning All tools can be cleaned immediately after use with Solvent 10. Limitations Durafloor V Anti-Skid should not be applied on to surfaces shown to or likely to suffer from rising damp conditions or have a relative humidity greater than 80%. Durafloor V Anti-Skid should not be installed is ambient
