For Polyurethane Membranes

Aquaprime PU Primer

PASCO Aquaprime PU Primer is a one part, low viscosity polyurethane based primer specifically designed to enhance the adhesion of Polyurethane membranes, such as Pasco Aquaproof 110 and Aquaproof 115 to porous substrates.

PASCO Aquaprime PU Primer is a fast drying polyurethane primer that seals concrete, compressed fibre cement sheet, plywood and other porous substrates. It provides a surface finish which is very receptive to polyurethane membranes and sealants.
