weberfloor primer

Product formerly named: EMIX Primer
Saint-Gobain Weber Hong-Kong

weberfloor primer is a dispersion of polymer in water with selective active agents to maximise penetration into substrate, and promotes good bond strength. The primer layer can effectively prevent air bubbles trapped in the substrate from diffusing into the self-levelling screed, which could otherwise cause pinholes on the surface of self-levelling screed. It is water-based, non-toxic, and has excellent adhesion to a wide range of substrates such as concrete and cement sand screed.
