ACTFLEX 700 PU PRIMER
Single-component, high-build, moisture-curing polyurethane
High-build, moisture-curing polyurethane primer designed to enhance adhesion between solvent-based waterproofing membranes and joint sealants.
ACTFLEX 700 PU PRIMER is a single-component, high-build, moisture-curing polyurethane primer formulated for maximum adhesion to porous and semi-porous substrates. It is designed specifically for use with Forspec’s solvent-based polyurethane waterproofing membranes and joint sealants.
The product forms a durable intercoat bond, enhancing chemical resistance and waterproof performance while ensuring long-term stability under Forspec membrane systems.
Suitable for new and old concrete, render, masonry, timber, bricks, CFC sheeting, and Villaboard, it can also be used to reactivate or bond existing polyurethane membranes.
