Primer for Liquid Waterproofing Membrane

Alfa Tiling Primer is used to prepare the subfloor for 811 Alfa Liquid Membrane fluid-applied waterproofing membrane for tiling. It is suitable for porous and lightly absorbent subfloors. The blue tint makes it easy to see where primer has already been applied and where it is still missing.
