Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 12 in. width is a good middle choice for reinforcing membrane laps, flashing transitions and split repairs. Keep the fabric wrinkle-free while rolling it into wet coating, and back-roll to fully encapsulate. For narrow flashing detailing choose a narrower roll; for full field reinforcement step up to the 40 in. width.
Follow roof safety practices and the coating manufacturer's safety data sheet when applying coatings over the fabric.
