WH6981 Waterproof Penetrant - General Purpose

GRASi® WP6981 is a high effective waterproof agent developed to provide water repellency for porous construction materials such as aerated concrete block, cement, brick, ceramic tile, tile, building insulation material and light weighted composite construction material etc.

The active ingredients which is nano-size penetrate deeply into the substrates and bond with them, form penetration protective layer on the surface. With super low surface tension, it boosts water repellency and fast beading action.

Features
