Sealmastic emulsion-type dampproofing is a breather-type which permits moisture vapor to escape through the film, while remaining resistant to water penetration. This prevents blistering of applied films. The product can be applied to green concrete (not totally dry). Sealmastic Type III (trowel-on grade) is a trowel-applied mineral colloid, asphalt emulsion, fibrated with selected fibers and produced in an ideal, light trowel application consistency. Sealmastic Type III offers high weather, water, corrosion, and abrasion resistance. It can be used as an adhesive on foam board installations.
