People Also Ask

PERMAMAT™ is a high-strength polyester reinforcing fabric designed to strengthen roof coatings and waterproofing systems. It is commonly used to reinforce roof seams, flashings, penetrations, cracks, transitions, and larger repair areas. When saturated with a compatible elastomeric coating or primer, it creates a durable reinforced membrane that helps prevent water intrusion and extends the life of the repair.

Unlike traditional fiberglass matting, PERMAMAT™ is made from 100% continuous filament polyester, making it flexible, conformable, and non-irritating to handle. It resists rot, mildew, and many chemicals while maintaining its strength even when wet. Its design also allows coatings to fully saturate the fabric, eliminating trapped air pockets and creating a stronger waterproof reinforcement.

Yes. PERMAMAT™ can be used on a wide variety of roofing substrates when paired with a compatible primer or elastomeric roof coating. It works well on metal roofs, concrete roofs, modified bitumen, and many other roofing systems where reinforcement is needed. Always verify compatibility with the coating or primer being used.

Begin by cleaning and preparing the surface. Apply a compatible primer or elastomeric coating to the repair area, then embed PERMAMAT™ into the wet coating. Press the fabric firmly to remove wrinkles and ensure complete saturation. Apply an additional coat over the fabric to fully encapsulate it before applying the final roof coating system as recommended.

PERMAMAT™ is available in convenient 18-inch × 100-foot and 36-inch × 100-foot rolls, with additional sizes available for larger commercial or specialty applications. These options make it easy to reinforce everything from small roof repairs to large waterproofing projects.
