Various products may be used as a liquid moisture barrier, air barrier, vapor barrier or some combination of the three. These products can be in sheet form or liquid applied. The advantages of liquid applied barriers include that they create a continuous, seamless barrier and are flexible to accomodate building movement. This CP describes a one component, liquid-applied, water-based, air, vapor and liquid moisture barrier. This type of barrier can be polymer based or polymer-modified asphalt based, the latter being described here. These barriers are applied by roller, brush, or spray and may be applied to most common surfaces, including concrete, CMU, and sheathing panels. Intended for cavity walls to be covered with an exterior finish.
