Gripset BRW PFN is a 1 mm self-adhesive butyl rubber sheet membrane with a fabric-laminated face, designed for high-performance waterproofing across internal and external floor areas. Its high-tack backing provides immediate adhesion, while the flexible sheet accommodates vibration, movement and substrate flexing and supports direct application of compatible cement-based tile adhesives, screeds and toppings.
Suitable for bathrooms, laundries, balconies, decks, podiums and terraces, BRW PFN can also be incorporated into hybrid Gripset systems with compatible liquid waterproofing membranes. The membrane complies with AS 4858 and AS 4654.1.
Important: For horizontal surfaces only. The membrane must be covered and must not be used as an exposed or trafficable finish, over expansion joints, or with solvent-based finishes applied over it.
