TREMstop Acrylic is a gunnable acrylic latex sealant designed for use in firestop applications, including both joints and through-penetrations.
TREMstop Acrylic is for use on metal pipe, plastic pipe, insulated pipe, cables, cable trays, ducts, static joints and dynamic joints in fire-rated concrete, wood floor/ceiling and gypsum wall assemblies. TREMstop Acrylic can also be used on acoustically rated assemblies.

Not recommended for use with passive fire containment systems not listed or approved by Tremco.
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 www.tremcosealants.com/commercial/firestop.
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.
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.
