Description 

EH MVB22 is 4:1, 100% solids, 0 VOC, two-component epoxy resin-based primer based on phenolic amine chemistry specifically designed as a moisture barrier for concrete floors with very high residual moisture prior to laying floor coverings, coatings, or parquet. (up to 25 lb./24 hr./1000ft2).


EH MVB22 is Also suitable on calcium sulphate-based screeds with slightly higher residual moisture.
As a primer for absorbent, non-absorbent as well as smooth surfaces.
For interior and exterior use. 


Concrete slabs at ground level emit invisible moisture vapor. The permissible moisture emissions for concrete are 3 lb./1000ft2 over 24 hours (<4%) based on calcium chloride test. In addition, a relative humidity (RH) test can be performed to test for moisture vapor. Relative humidity test results should be less than 85% per ASTM F2170. If humidity is above this level, blistering and delamination of the coating may occur. A calcium chloride or relative humidity test should be performed to determine the moisture levels of the concrete. If humidity levels exceed 85% for RH test or 3 lbs. for calcium chloride, the EH MVB22 concrete moisture vapor control system is designed to be used before applying the coating system.


Uses

Where the concrete moisture content exceeds 4% or, 3 lb./1000ft2 over 24 hours.
