Mastix™ Butyl Tape
This versatile, trimmable, end-lap sealing tape joins metal to metal, and seals around windows, doors, roof vents, stacks, access doors and other penetration points. Non-staining and permanently flexible, Mastix stays in place with no melting or oozing, even in extreme heat.
Roll Mastix Butyl Tape out on through-fastened and standing seam panels, removing the release paper to expose adhesive.
Position panel over Mastix.
When positioned, press panel down on Mastix and fasten in place with QuikDrill™ or QuikGrip™ fasteners.
