ActFlex 500 NP Primer – Non-Porous Primer

ActFlex 500 NP Primer is a solvent-free adhesion primer designed to promote strong bonding to non-porous, dense and smooth substrates prior to the application of waterproofing membranes, adhesives and polymer-modified mortars. It provides exceptional adhesion without the need for solvent etching, making it suitable for both internal and external applications.

Suitable for a wide range of substrates including metals, existing ceramic tiles, glass, compressed fibre cement, marine plywood, rigid plastics and painted surfaces, ActFlex 500 NP Primer dries to a non-tacky finish and can be overcoated with compatible FORSPEC membrane systems.
