Expert Verdict — Reviewed by the SuperArbor Pro Desk
EPDM is notoriously difficult to coat directly, so a rinseable pre-treatment like PolyBrite 78 is a key step for restoring an aged rubber roof. Spray it on, power wash, then apply the elastomeric coating for maximum bond. For unusual substrates or project conditions, confirm with Polyglass Technical Services before proceeding.
Use standard pail-handling and fall-protection practices when priming a roof, and follow the product's application instructions.
Order Polyglass PolyBrite 78 Rinseable EPDM Primer to prep your EPDM roof for coating.
