SmartFlash ONE is a one-component, UV-stable, fluid-applied resin for steep and low-sloped roof flashing details and repairs. It offers roofing contractors an economical and convenient waterproofing solution in a ready-to-use, re-sealable can that requires no measuring or mixing to activate. Unlike two-component flashing products that require primer or component mixing, contractors can work quickly without fear of the product setting up too fast or going to waste.
