Reinforcing fabric membrane supplied in a narrow roll for use with asphalt roof cement, mastic or hot-applied bitumen. The open-weave fabric is bedded into a coat of cement and then covered with a second coat, so the cured repair behaves as a single reinforced layer rather than a skin of mastic that can crack or sag.

The narrow width suits linear work: seams, laps, flashing joints and cracks, where a full-width roll would be wasteful and difficult to work into corners. The fabric can be cut with a knife or shears and conforms to curbs, pipe collars and parapet transitions without cutting relief darts on most details.

Used on built-up, modified bitumen and other asphalt-based roof assemblies, as well as on asphalt-coated metal and masonry surfaces that are being patched with a compatible cement.

Key Features

• Open-weave reinforcing fabric designed to be embedded between two coats of asphalt roof cement
• Narrow roll width intended for seams, joints and linear crack repair
• Distributes stress across the repair and helps bridge minor movement and hairline cracking
• Holds mastic at a consistent thickness so the patch does not thin out or sag on slopes
• Cuts cleanly with a utility knife or shears and conforms to curbs, corners and penetrations
• Compatible with asphalt-based cements, mastics and bituminous coatings

Applications

• Reinforcing patches and cracks in built-up and modified bitumen roofing
• Stripping in base flashings at parapets, curbs and walls
• Sealing around pipe penetrations, vents and roof drains
• Repairing seams and laps in asphalt-coated metal flashing and gutters
• Reinforcing mastic details at skylight and equipment curbs
• Patching asphalt-coated masonry and foundation waterproofing detail work
