Henkel Bitumin Drum Polycoat - 16L
► Resists the attack of salts like chlorides and sulphates that are present in the soil ► Easy to apply ► Cold applied ► Adheres to concrete, metal, wood, cork, etc. ► Can be applied in closed or confined spaces ► Water-based ► Versatile ► Anti-fungal ► Economical DESCRIPTION Polycoat is an emulsified thixotropic bitumen protective coating. The coating dries to form a black flexible protective film. The finished film forms a tough barrier to vapor transmission. Fields of application Polycoat is used for providing damproofing for below ground concrete structures which are above the water table. This can also be used as the protective coating for built-up roofing systems and other exposed surfaces. The coating is also used as a moisture vapor barrier on block works and concrete surfaces.
Application instructions :
The application temperature should be between 5°C to 55°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the bitumen coating is as follows:
Surface preparation The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections and protrusions are to be removed and repaired. Structurally unsound and friable concrete must be removed and repaired with a suitable Polycrete* concrete repair mortar.
Priming Polycoat doesn't require priming and can directly be applied on to concrete surface. Incase highly porous surface, a priming coat may be applied to seal the pores and stabilize the surface by diluting the same bitumen emulsion with 20% water. Apply the primer coated at approx. 4m2/L allows to dry.
Application Stir the contents of the drum thoroughly prior to application to remove any sediment. The application can be done with a roller, brush or suitable industrial spray. Apply the coating at a coverage rate of 1-4 m2/L/coat, depending on the dry film thickness required. For highly demanding situations, it is recommended to apply in multiple coats. Further coats shall be applied only after the previous coat dries off completely. However, the coverage depends on the smoothness and porosity of the substrate and the required thickness of the coating.
Protection The coating shall be protected from ongoing site activities and during backfilling from getting damaged by a 150 micron polyethylene sheet.
