Gripset BRW-PFN is a self-adhesive butyl rubber sheet membrane with a polypropylene fabric facing that supports the application of surface finishes for waterproofing internal and external areas. The high tack butyl backing provides a high-performance waterproof layer with outstanding resistance to vibration, movement and flexing, delivering a waterproofing system that overcomes the limitations of liquid membranes and bitumen tack sheet membranes.
Forming an instant waterproof seal when applied onto surfaces, BRW-PF the system avoids downtime for drying or curing, enabling surface finishes and adhesives to be applied directly over. BRW-PF can be finished over with Gripset adhesives, membranes, coatings, screeds, mortars, renders and approved decorative finishes.
