Dex-O-Tex, a division of Crossfield Products Corp., introduces Vapor-Shield, a polymer-modified, trowel-applied compound designed for use under finished flooring to combat moisture vapor transmissions (MVTs) present in the concrete substrate.

Vapor-Shield also serves as an underlayment for smoothing, leveling or flattening surfaces, or to provide slope to drain. In addition to its function as an MVT retardant, Vapor-Shield provides positive side waterproofing, according to the company.
