DAFA SprayBarrieris a sprayable liquid vapor barrier used where it is tough to seal using a traditional vapor barrier.
DAFA SprayBarrier is a low-viscosity one-component sealing compound based on hybrid polymer technologies. It is chemically neutral, has only a faint odor, and is compatible with most common construction surfaces. DAFA SprayBarrier cures by reacting with moisture in the air to form a solid, elastic, weatherproof, and airtight coating with good UV resistance.
