Moisture Vapor Reduction System under resilient flooring systems

Moisture penetration through concrete slabs can cause severe problems for subsequent resilient flooring systems.  High concentrations of moisture and alkalinity (levels determined through testing) can lead to the deterioration of flooring adhesives and delamination of coatings by osmotic action.  Even with relatively low moisture vapor emissions (MVER), elevated alkalinity can compromise even the toughest flooring system adhesives.  To avoid this problem, the concrete slab should be sealed with a material that will tightly bond to the concrete under these very adverse conditions.

KOSTER VAP I 2000 is a special material which fulfils all of these functions; it has a very low permeance rating (ASTM E-96 wet method: 0.04-0.09), excellent bond strength, and is resistant to sustained high alkalinity (pH 14).  The KOSTER VAP I 2000 moisture vapor reduction system is applied to properly prepared, solid and sound substrates that are free of bond inhibiting substances.  In certain situations, resilient flooring (i.e. VCT, sheet vinyl, etc) may be applied directly to the KOSTER VAP I 2000.

Always adhere to the manufacturer's specifications for use over a non-prous substrate as well as the respective Technical Guidelines.
