Polyscreed PU primer FS
Fast Set Polyurethane Concrete Primer
Polyscreed PU Primer FS is a three component, quick setting 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 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.
