WPA 260

WPA 260 is a uniquely formulated single component vapour barrier for use over concrete and cementitious screeds to prevent blistering and delamination of the WPA range of water-based membranes associated with residual dampness within the substrate.

Unlike traditional vapour barriers, WPA 260 will not change the surface profile, ensuring the membrane bonds as designed.

​

• Forms a vapour barrier against residual moisture.

• Fast drying, enabling membrane application after only one hour.

• Can be applied over damp and green concrete or cementitious screeds.

• Water resistant.

• Unique colour changing formulation indicating when product is ready for overcoating.

• Designed to be used with the WPA range of water-based membrane systems on porous surfaces.
