Silicone acrylic, micronized, water-based primer. It offers excellent bonding, high penetration as well as durability to alkaline surfaces. Penetrates and anchors to the porous of the substrate, waterproofing it while allowing it to breathe. It also protects from rising moisture and salts stains. Furthermore, it has the ability to harden weak substrates, such as brittle plasters, etc. It has a slightly yellow color in order to be easily visible in fully primed surfaces.
