Soprema (Wadsworth, OH) has expanded its Sopraseal line to provide liquid air-barrier membrane products that can be brush, roller or spray applied behind a variety of substrates, including brick, EIFS and stucco.

The Sopraseal line features waterproofing and air and vapor barriers used in wall construction. While the line already featured self-adhered stick-on membranes, the new products—Sopraseal LM 202 VP and Sopraseal LM 203—come in liquid form, according to the company.

Sopraseal LM 202 VP is described as a vapor-permeable air barrier; LM 203 is a nonpermeable formulation.

Both are one-component, ultra low VOC, water-based formulas, according to product literature.

“In addition to ease of installation, [the products create a surface that] can be easily cleaned with water,” Soprema’s Business Development Manager Jack Garnett notes.

Cold-Temp Friendly

Both products can be applied (with the help of an additive) at temperatures as low as 25 degrees Fahrenheit, the company says.

Soprema offers a portfolio of building envelope products, including roofing and waterproofing materials in addition to wall-system materials.
