ACTFLEX 300 Primer
High-adhesion primer
Exceptional bonding for Butyl membranes, screeds, and cementitious or water-based waterproofing systems.
ACTFLEX 300 is a high-adhesion primer designed for multiple roles within Forspec systems. It penetrates deeply to provide strong bonding on PVC, masonry, and concrete surfaces. The product serves as a primer for Forspec Butyl series membranes, acts as a chemical binder in screeds through slurry coats and admixtures, and functions as a primer for Forspec cementitious and water-based membranes when specified. It improves screed strength, reduces shrinkage, prevents delamination, controls dusting, and is easily applied by brush, roller, or spray.
