3/32" x 1" - 45 ft. Roll
Mastix™ is Marco’s versatile, trimmable end lap sealing tape that joins metal to metal, and seals around windows, doors, roof vents, stacks, access doors and other penetration points. The superior adhesive on Mastix keeps the product roll intact and prevents it from telescoping even on hot days. Apply Mastix to a hot metal roofing panel and it will stay put while you place the panel. No melting, oozing adhesive allowing panels to slide, making your installation harder. Plus, Mastix won’t stain or lose its flexibility.
Flexible metal-to-metal adhesive that stays in place, even in extreme heat.
