MVB22 2.5 Gallon Kit-Moisture Vapor Barrier

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 22 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.   Coverage Rates/Price per square foot 100 square foot per gallon (250 square feet per kit)  Approx. $0.83 a sq foot    Characteristics Made from 100% solids Resistant to chemical loadings Good penetration Can be applied to almost all substrates Grip promoting Suitable for application on subfloor heating systems Resistant to bacteria and moisture Exceeds ASTM F3010 standards 0 VOC Suitable on damp substrates High sealing function For increased residual moisture and single-layer application Magnesite screeds Old sealed/coated surfaces Impermeable and seamless.
