ACTFLEX SA TAPE
SELF-ADHESIVE BUTYL SEALING TAPE 10mmx10m
self-adhesive butyl sealing tape engineered to simplify waterproof detailing while delivering long-lasting protection against water ingress.
FORSPEC ACTFLEX SA TAPE is a high-performance self-adhesive butyl sealing tape engineered to simplify waterproof detailing while delivering long-lasting protection against water ingress. Manufactured with premium butyl technology, the tape provides exceptional adhesion to common building substrates without requiring heat, primers, or additional adhesives in most applications.
Its highly malleable construction allows it to conform easily around corners, penetrations, floor wastes, pipes, wall-to-floor junctions, precast panel joints, and other complex detailing areas. The fleece-faced surface is specifically designed to bond seamlessly with liquid waterproofing membranes, ensuring a strong mechanical and chemical connection between the tape and the applied waterproofing system.
