Expert Verdict Reviewed by the SuperArbor Pro Desk

Use PolyBrite 39 as the detail mastic under elastomeric coating systems, working it into flashing terminations, fastener heads and seams before the base coat. Apply when temperatures and drying conditions allow water-based products to cure properly. Keep a Tan pail on hand where the detail color should blend with a tan coating system.

Wear gloves and eye protection when applying mastics, and follow the manufacturer’s safety data sheet for handling and cleanup.
