POLYPRIME PS is a single component solvent based adhesion promoting primer for movement and control joints in porous substrates like concrete, block work, asbestos and timber. The primer forms a chemical bridge between the concrete surface and the sealant which is applied into the joint.
Strengthens the adhesion of joint sealants to porous surfaces such as concrete, cement brickwork, gypsum board, timber and stone
Stabilizes and seals joint surface particularly in harsh environments such as areas subjected to
heavy traffic, saline water, fuel or oil spillage areas
