Rain Safe Leak Repair
Extreme-Weather Leak Protection That Cures in the Rain
Rain Safe Leak Repair is a one-of-a-kind waterproofing coating that adheres to wet or damp surfaces and cures—even underwater. Engineered with Kevlar® reinforcement and advanced polymer chemistry, this durable, brushable membrane provides long-lasting leak protection when you need it most. Whether it's raining, humid, or the surface is still damp from repairs, Rain Safe bonds immediately to most roof types and begins forming a seamless, watertight seal on contact.
Unlike typical quick-patch products, this solution is built to last, maintaining flexibility in cold weather, resisting UV and ponding water, and bonding permanently without re-emulsifying. It's your go-to for emergency repairs that don't need to be redone later.
