Waterbased PU Coating

Polythane P (Waterbased PU Coating) is a single component Liquid applied waterbased polyurethane waterproof coating.

Waterbased PU Coating is a waterproofing and protective coating for concrete structures based on a
hybrid Polyurethane. The Polyurethane is modified with specially selected polymers to form a tough,
flexible and durable coating. It is completely free from coal tar and other hazardous ingredients.

Waterproofing or vapor barrier protection of:  Wet areas like kitchens, bathrooms, toilets, public showers, exposed roofs, domes, terraces, balconies and patios.

Features

Polythane P forms a highly elastomeric, tough and resilient membrane. It is environment friendly and has Low VOC and Coal tar free.
It has high tensile strength and elongation with excellent crack bridging properties

Waterbased PU Coating has an excellent UV resistance, weatherability and color retention properties. Very good resistance to water and vapor and high chemical resistance against diluted acids and alkali, oil, salts, bacteria, and common fuels.

Surface Preparation

All the surfaces must be cleaned and made free of dust, dirt, moss, oil, grease and other loose particles. This can be achieved by grit/sand/shot blasting. As a minimum, vigorous wire brushing should be employed. All pin holes and surface defects shall be repaired with a suitable concrete repair mortar.

Priming

POLYTHANE P does not require priming and can directly be applied onto the concrete surface. In case of highly porous surface, a priming coat is recommended to seal the pores and stabilize the surface. The primer coat can be produced on site by diluting POLYTHANE P 1 to 1 with water. Apply the primer coat @ 5m²/lt and allow to dry.

Mixing

POLYTHANE P is a single component product but mix the contents of the pail thoroughly prior to application to remove any sediment. A slow speed drill and suitable paddle mixer shall be used to avoid the formation of air bubbles.

Application

The coating can be applied with a brush, roller or airless spray and shall be applied in a minimum of 2 coats. The 1st coat shall be allowed to dry completely before the 2nd coat is applied. The 2nd coat shall be applied cross wise to the first coat. The coating will achieve its full strength after a curing period of 7 days.

Corner Detailing

It is recommended to reinforced all corners with CL 252 sealing strip. The sealing strip shall be embedded into the first coat whilst it is still wet and covered fully with the second coat.
