SealMastic Dampproofing Coatings

SealMastic zero-VOC, asphalt-based dampproofing coatings are resistant to moisture infiltration in foundation walls, tanks, bridge abutments, and other above- or below-grade concrete surfaces while also creating a breathable barrier that allows moisture to escape.

    Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.

SealMastic zero-VOC, asphalt-based dampproofing coatings are resistant to moisture infiltration in foundation walls, tanks, bridge abutments, and other above- or below-grade concrete surfaces while also creating a breathable barrier that allows moisture to escape. SealMastic is available in both emulsion and solvent formulas, both available in three forms for spray, brush, or trowel application.

07 16 00: Cementitious and Reactive Waterproofing

While most conventional concrete sealers and waterproofing agents have very high VOCs, some products react with the concrete or otherwise provide a seal without resorting to solvents that emit VOCs.

Products listed here contain zero VOCs, either nominally or actually.
