It is a water-based resin that acts as an adhesion promoter between a non-porous surface (tile, marble, metal or terrazzo) and microcement. It stands out for its high adhesion and for the permanent maintenance of adhesion (residual adhesion), which allows a long action time in the application of the subsequent layer of microcement. It has great elasticity that makes it excellently resistant to different climatic conditions. Volume: 1l, 5L, 25L
