Coverage & How Much You Need:
Each roll runs 150 ft. long, so a 4 in. roll yields 50 sq. ft. of reinforcing fabric and a 36 in. roll about 450 sq. ft. Choose a width at least slightly wider than the seam or crack you are reinforcing so the fabric laps onto sound substrate on both sides.
Fit and Compatibility:
Designed for use with United Asphalt and other asphalt-based roof coatings, cements and mastic systems. Embed the fabric into a wet layer of coating or cement and recoat over the top; specific coating systems should be verified against their manufacturer instructions.
Frequently Asked Questions (FAQ):
Q: What is included in an order?
A: One roll (or carton, depending on width) of asphalt-saturated cotton fabric in the selected width, 150 ft. long.
Q: How much area does one roll cover?
A: 150 linear feet of reinforced seam or flashing; a 4 in. roll covers about 50 sq. ft. of fabric area and a 36 in. roll about 450 sq. ft.
Q: How is it installed?
A: Apply a layer of asphalt coating or cement, embed the fabric into the wet material, then cover with additional coating or cement so the fabric is fully encapsulated.
Q: Which width should I choose?
A: Pick a width that extends past the seam or crack onto sound substrate on both sides; narrow widths suit seams and patches, wide widths suit larger membrane reinforcements.
Q: Is it compatible with acrylic coatings?
A: It is intended to provide a bond between coatings and cements; always confirm wet-on-wet embedment procedures with the coating manufacturer's instructions.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Asphalt-saturated cotton fabric is a staple for reinforcing flashings, seams and splits before topcoating a roof. Use the narrow 4 or 6 in. rolls for seam and flashing work and the 12 or 36 in. rolls for bridging larger splits or membrane reinforcement. Embed while the cement or coating is wet and keep the fabric tension-free so it follows the substrate without bridging.
Wear gloves and eye protection when working with hot or solvent-based asphalt cements and coatings, and follow the roofing manufacturer's safety guidelines.
Order United Asphalt Saturated Cotton Fabric in the width you need for your next coating or cement repair.
