TEC The LiquiDAM Penetrating Moisture Vapor Barrier delivers less than .1 permeability of water vapor through the membrane.
Moisture penetration through concrete slabs can cause severe problems for flooring systems. Even relatively low moisture emissions (MVER) can lead to the deterioration of flooring adhesives. The LiquiDAM delivers a high level of moisture protection, along with time and labor saving benefits. The formula requires no shot blasting for clean, sound concrete and allows same-day flooring installation with a one-coat, fast-drying formula that cures in 4-5 hours and exceeds the ASTM F3010-13 standard for moisture vapor barriers. When used as a complete TEC system with other surface preparation products and flooring adhesives, The LiquiDAM also qualifies for a 20-year Moisture Control Limited System Warranty.
The LiquiDAM Penetrating Moisture Vapor Barrier can be applied to new or existing concrete with a maximum relative humidity of 100% and a moisture vapor emission rate of 25 lbs per 1000 square-feet per 24 hours. Applied with a squeegee or a 1/16” square notch trowel and a 3/16” nap foam roller, one coat boasts more than 150 square feet of coverage depending on surface porosity.
