VAP I 2000 FS




KOSTER VAP I® 2000 FS is a fast-setting, one-coat, membrane-forming, moisture vapor control system consisting of a unique combination of epoxy resins and other compounds formulated to prevent floor covering failures on concrete slabs with elevated levels of moisture.

KOSTER VAP I® 2000 FS meets or exceeds the performance requirements in ASTM F3010-13 Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings.

Key Features:

KOSTER VAP I® 2000 FS has no upper limit for water vapor emission from concrete floor slabs. It can be applied to concrete slabs with relative humidity up to 100% RH and it provides protection from sustained exposure to pH 14.

Due to its unique formulation, KOSTER VAP I® 2000 FS is extremely effective at blocking moisture. With a low permeance of 0.047 perms, KOSTER VAP I® 2000 FS is an excellent moisture blocker for virtually all types of flooring, including low permeance flooring such as sheet goods and rubber tile.

VOC Compliant

KOSTER VAP I® 2000 FS is compliant with all state and federal VOC regulations, having VOC content of 0 g/L, which allows installation in sensitive areas such as hospitals, schools, and grocery stores. LEED Indoor Environmental Quality Credits are available for EQ 4.2 (Low-Emitting Materials, Paints and Coatings).

PackagingCoverage Rate
2.4 gal kit360 sq. ft. / kit
*Based on coverage rate of 150 sq. ft. / gal 
KOSTER VAP I 2000 FS moisture control coating must be installed at a minimum continuous layer thickness ≥ 11 mils (0.011 in). Spread rate on ICRI CSP 3 surface is not to exceed 150 sq ft/gal. A rougher surface profile or porous or absorptive concrete will require more material to achieve a sufficient coating thickness.
