Polyscreed PU primer
Polyurethane Concrete Primer
Three-part, cement modified, polyurethane resin primer designed for use with the Polyscreed PU range of products. The applied product forms a watertight moisture barrier and in doing so reduces the chance of pin or blow hole formation in subsequent cementitious polyurethane systems. When applied to a correctly prepared substrate, the bond strengths are in excess of the concrete cohesive strength and thus forms an excellent bonding surface.
