Expert Verdict — Reviewed by the SuperArbor Pro Desk
Reinforcing fabric is what turns a coating into a true membrane at details. Embed it fully into wet coating with no dry spots or wrinkles, and strip in every seam and penetration rather than spot-treating. Keep a 4 in. roll on hand for pipes and a 12 in. roll for curbs and equipment bases.
Work carefully around roof penetrations and equipment, and follow the coating manufacturer's safety data sheet during application.
Order JM Coating Polyester Reinforcing Fabric in 4 in., 6 in., or 12 in. rolls for your liquid-applied roof job.
