Mouldcraft bond x grp primer is a polyurethane solution that massively improves bonding of polyester resins to concrete, wood and metal. Prymax moisture curing system means it can be applied in damp (not wet) conditions and low temperatures. When Prymax is partially cured, polyester resins will chemically bond, making it an excellent primer for bonding GRP to porous and metal substrates.
