Optimum performance will be achieved when applied to clean, dry, dust and grease-free surfaces. Excellent adhesion to plastic, wood, metal and masonry. Recommended size application, 100mm & 70mm for polyethylenes, polypropylenes and butyl. 100mm, 70mm & 50mm for gas barriers. 30mm & 15mm radon barriers.
Keyseal Tape must be applied to a dry surface into a 150mm overlap of the membrane and pressed down firmly to achieve a gas tight seal. The tape should only be applied at temperatures above 5°C.
Polybutene, inert fillers and oil with elastomeric backbone, formed into an homogeneous tape carried on a release paper.
