Storage and Installation Guidance: Permatac Butyl Tape should be applied to surfaces at a temperature range of between +4°C and +40°C. For best performance the surfaces should be clean, dry, and grease free. The product should be unwound and lightly pressed into position leaving the release paper in place. On forming the joint the release paper is removed and the closing surface pushed firmly in place, pressure applied along the length of the joint and mechanically fixed. Â
