Aurora, Ill.—TEC announces The LiquiDAM Penetrating Moisture Vapor Barrieris now new and improved, delivering 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 new and improved formula, available in August 2013, delivers a higher level of moisture protection than the current version while keeping the same time and labor saving benefits. The formula continues to require no shot blasting for clean, sound concrete. This also allows for same-day flooring installation with a one-coat, fast-drying formula that cures in 4-5 hours and exceeds the newly released ASTM F3010-13 standard for moisture vapor barriers. When used as a complete TEC system with other surface preparation products and flooring adhesives, The LiquiDAMalso qualifies for a 20-year Moisture Control Limited System Warranty.
“The LiquiDAM protects flooring systems from the damage caused by severe moisture and alkalinity, says Grant Huffine, market manager for H.B. Fuller Construction Products. “It is a superior moisture mitigation solution that exceeds the new performance levels in the industry while providing installation advantages.”
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.
