Cross - link technology the chemical bond between the PU, Durorproof PUM or DUROPRIME is exceptionally strong. PU as a primer Improves the adhesion and preformance of the membrane 'locks - down' dust and loose materials improves the spreading and application of the subsequent membranes, provides a penetrative secondary waterproof barrier and improves the coverage of the DUROPROOF PUM and DUROPRIME membranes. DUROPRIME PU PRIMER is a penetrative sealer and provides a penetrative waterproof barrier when applied in 2 coats or more. DO NOT use as a primary waterproofing membrane . Use only in conjunction with DUROPROOF PUM waterproofing membranes . The PU dries by evapouration of the solvent and then cures upon contact with water vapour in the air. Read More
