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 grains/sq ft/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.
