DAFA SprayBarrieris a sprayable liquid vapor barrier used in places where it is very difficult 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.
Very easy to handle and apply
Easy sealing for complex joints
Can be sprayed, caulked, or brushed on
Free of solvents, isocyanate, and silicone
May be applied to damp surfaces
Extremely low values when tested for airtightness (0,0098 l/s pr. m2)
DAFA SprayBarrier can be applied as a sealant to the substrate.
DAFA SprayBarrier bag with 600 ml. and spray gun
The optimal solution for airtightness is to use DAFA SprayBarrier and DAFA ExFoil together.
