PRIMER PU is a single-component polyurethane primer for use on highly porous surfaces such as concrete, plaster and wood. It can be used as an anti-corrosion coating on metals. The bonding occurs as a result of a reaction with air humidity.
PRIMER-PU concrete primer provides excellent adhesion to the substrate, strengthens its structure and protects against moisture absorption. Thanks to its formula, it effectively penetrates the surface, improving the durability of applied polyurethane coatings and eliminating the risk of loosening of top layers.
