Expert Verdict — Reviewed by the SuperArbor Pro Desk
PermaFlash is a go-to solution for complicated bituminous details, such as pipe clusters, drains and irregular vertical terminations, where membrane flashing is hard to form. Prime first, embed the scrim fully into the flashing cement without bridging, and top-coat to encapsulate the fabric before the cement skins over. At 150 sq ft per kit, one kit usually handles the scattered details on a typical reroof, so verify quantity before mobilizing.
Use flashing cements, primers and activators with adequate ventilation and proper personal protective equipment, and keep solvent-based materials away from ignition sources.
Order the JM Permaflash Complete Kit and tackle your next bituminous flashing details with one integrated system.
