Mineral wool is recommended as joint backing to control sealant depth and insure intimate contact of sealant with cavity wall when tooling. Certain types of backing material may be required by system. For additional information on firestop system components, please visit www.tremcosealants.com/commercial/ firestop.
At 77 °F (25 °C), 50% RH, TREMstop Acrylic SP is tack-free in 30 to 60 minutes and dries at a rate of about 1/8” (3.17 mm) per day. As the temperature decreases, the dry time of TREMstop Acrylic SP will increase, generally one additional day for every 10 °F (5.5 °C) decrease in temperature.
Excess sealant can be cleaned up or removed with soapy water before sealant skins. Clean sprayer in accordance with manufacturer’s recommended cleaning instructions.
