Foster® VAPOR-SAFE® mastic is a high solids, water-based, fire-resistive, flexible, vapor retarder finish for most types of thermal insulation, including polystyrene foam. It may be used over dry concrete and finishing cement. VAPOR-SAFE® mastic is non-flammable when wet and has a mild, latex "paint type" odor. It is designed for heavy-duty/industrial use over insulation on pipes, vessels, ducts and equipment operating below ambient temperatures. It may also be used indoors. VAPOR-SAFE® mastic has the water resistance and low water vapor permeance normally only found in solvent-based products. It can be used in high humidity environments and greatly retards water vapor permeation. VAPOR-SAFE® mastic is ideal for vapor sealing ASJ, FRK and FSK jackets and board facings at joints, laps and over staple and weld pin punctures. It is an excellent duct board closure sealant. Do not exceed 1/8 in (3.2 mm) wet film thickness. VAPOR-SAFE® mastic contains no asbestos, lead, mercury or mercury compounds. VAPOR-SAFE® mastic meets the requirements of Military Specification MIL-PRF-19565C, Type II using method ASTM E96, Procedure A permeance and is QPD listed.
