Expert Verdict — Reviewed by the SuperArbor Pro Desk
Granule blending is what separates an invisible flashing patch from a visible one; keep a pail of each membrane color on the truck so bleed-out and detail work can be finished while the mastic or liquid flashing is still tacky. Broadcast lightly and build up in layers rather than dumping. Moisture content of 0.3% max keeps the granules free-flowing in the pail.
Wear gloves and eye protection when broadcasting granules, and keep loose granules off walkways and ladders to prevent slips.
Order CertainTeed FlintRock Granules in your membrane color to blend flashing and lap details seamlessly.
