FlexCoat Wall Coating

FlexCoat Wall Coating is a liquid-applied, advanced acrylic elastomer designed to waterproof exterior vertical surfaces. FlexCoat Wall Coating is a flexible “breathing” membrane, allowing moisture vapor from the substrate or building interior to escape through the coating while remaining resistant to water penetration from the exterior. Available in a 5 gallon (19 liter) pail.

Approved Substrates: Vertical concrete and masonry building exteriors, and hardboard substrates.
