Perdure FE80 is flexible urethane modified epoxy used as a crack isolation membrane under various Duraamen flooring systems. Perdure FE80 resists cracking caused by horizontal substrate movement, providing a crack resistant, resilient, sound absorbent, waterproof, durable floor. When it is used with various flooring systems it offers stress-relieving properties for floor slabs that show movement or vibration. Perdure FE80 is also used to treat the surface of individual cracks and properly filled and covered contraction joints (saw cuts). It is available in a wall grade formulation.
