Moisture Vapor



KOSTER VAP I 2000 is a one-coat moisture vapor reduction system consisting of a unique combination of epoxy resins and other chemical compounds. KOSTER VAP I 2000 is formulated to prevent floor failures on concrete slabs containing elevated levels of moisture vapor emission. KOSTER VAP I 2000 has no upper limits for water vapor emissions; it resists high moisture levels (100% RH) and a sustained pH of 14. KOSTER VAP I 2000, due to its 12 hour cure and 100% solids content, is extremely dense with a perm rating of 0.09 grams/ft²/ hour in Hg-1. The low perm rating makes the KOSTER VAP I 2000 perfect as a primer for virtually all types of flooring, especially low permeance flooring, such as sheet goods and rubber tile.

Unit Size: 6 gal kit, 2.4 gal kit, 0.7 gal kit.



The KOSTER VAP I 2000 Zero VOC is a VOC free one-coat moisture vapor control system consisting of a unique combination of epoxy resins and other chemical compounds. KOSTER I 2000 Zero VOC is formulated to prevent floor failures on concrete slaps with elevated levels of moisture vapor emission. KOSTER VAP I 2000 Zero VOC is VOC free and is compliant with all state and federal VOC regulations. It allows installation in sensitive areas such as hospitals, schools and grocery stores. LEED Indoor Environmental Quality Credits are available for EG 4.2 (Low-Emitting Materials, Paints and Coatings).

Unit Size: 6 gal kit, 2.4 gal kit



The KOSTER VAP I 2000 FS is a one-coat moisture vapor reduction system consisting of a unique combination of epoxy resins and other chemical compounds. It is formulated to prevent floor failures on concrete slabs containing elevated levels of moisture vapor emission. It has no upper limits for water vapor emissions; it resists moisture levels (100% RH) and it provides protection from a sustained pH of 14. KOSTER VAP I 2000 FS, due to its 4 hour cure and 100% solids content, is extremely dense with a perm rating of 0.047 grains/ft2/hour in Hg-1. The low perm rating makes it perfect as a primer for virtually all types of flooring, especially low permeance flooring, such as sheet goods and rubber tile. IKoster VAP 1 2000 FS is compliant with all state and federal VOC regulations with a VOC content of 0 g/l. It 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).

Unit Size: 2.4 gal kit, 0.7 gal kit.



KOSTER VAP I 2000 UFS is a 100% solids epoxy designed to protect moisture sensitive adhered flooring systems from the
devastating effects of elevated moisture and high pH levels. It
is engineered on the same successful base formulation as the
KOSTER VAP I® 2000 but with a much faster set time of approx. 2 hours, which makes it ideal for fast tracking projects such as retail stores and other time sensitive projects. It is a true one-coat, topically applied moisture control system capable of reducing 25 lb of moisture vapor transmission to below 2 lb (ASTM F 1869). KOSTER VAP I® 2000 UFS may be applied to 100% RH floors and has low VOC’s and a tested low permeability of 0.06 perms.
