Excellent long-term resistance to damage from sunlight or extreme temperature fluctuations, ensures durable waterproofing performance.
Si-COAT 402WP is a silicone liquid-applied, cold weather and moisturecure, elastomeric, monolithic waterproofing silicone wall coating suitable for use in above-grade applications. The coating can be applied and cures from as low as -4°F up to 140°F (-20°C up to 60°C). This architectural coating can be used over masonry such as concrete, concrete block, brick, stone, EIFS, stucco, wood, and previously coated surfaces. It provides excellent weatherproofing protection, flexibility and durability with a long service life.
As a result of its specific chemistry, Si-COAT 402WP forms chemical bonds with the host surface to enhance adhesion properties without the need for priming and extensive site preparation. The single component, room temperature vulcanizing (RTV) moisture cure polysiloxane technology provides superior performance and durability by allowing internal moisture vapor to diffuse out, and exterior water to be repelled. This unique ability protects surfaces from dampness, weather damage, wind-driven rain and allows drying from within the substrate. Also, due to the hydrophobicity of the coating, the surface can easily be cleaned using water under low pressure.
