Joint Description:
Mineral wool, closed cell, or reticulated polyethylene backer rod 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

Cure Time:
At 77 °F (25 °C), 50% RH, TREMstop Acrylic is tack free in 30 to 60 minutes and dries at a rate of about 1/8” per day. As the temperatures decrease, the dry time of TREMstop Acrylic will increase, generally one additional day for every 10 °F decrease in temperature.

Clean Up:
Excess sealant and smears can be cleaned up or removed with soapy water before sealant skins. Any utensils used for tooling can also be cleaned with soapy water.
