Expert Verdict — Reviewed by the SuperArbor Pro Desk
Embed scrim fully wetted into the PMMA resin, working it out flat with no wrinkles or dry spots, then top-coat immediately so the fabric is fully encapsulated. Plan laps so edges overlap the system's specified amount, and keep the 13.8 in. roll on hand for vertical details where the wide roll cannot conform. Buy field and detail rolls separately to control waste.
Handle and trim reinforcement fabric with care, wearing gloves to protect against fiber irritation and cuts from utility knives.
Order Johns Manville PMMA Scrim in 13.8 in. or 41 in. rolls for reinforced PMMA membrane strength.
