Expert Verdict — Reviewed by the SuperArbor Pro Desk
PMMA liquid flashing excels at complex penetrations, drains and vertical details where sheet flashing is hard to detail; only mix what you can apply within the working time. Order catalyst and scrim with the resin and match the grade to site temperature. Two-part PMMA systems require trained applicators and correct mix ratios.
PMMA resins are reactive chemicals; wear appropriate PPE and ventilate work areas, and follow the manufacturer's safety data and application temperatures.
