How Does Elastomeric Flashing Work? The Best Solutions for Your Project

Long-lasting, easy-to-use elastomeric flashing sealants provide weatherproofing protection. Properly installed, they prevent leaks at flashings in walls, gypsum sheathing, vents, skylights, chimneys, and stacks and fill gaps at head joints, minor cast concrete cracks, concrete masonry cracks, gypsum sheathing joints, and penetrations. In addition, elastomeric properties keep the flashing flexible over time, to resist brittleness.
