Firestop Mortar
SpecSeal® Firestop Mortar is an economical, light-weight portland cement-based firestop product. This passive (non-intumescent) material utilizes a combination of heat sinking and insulating properties to provide an extremely high level of fire resistance. SpecSeal® Firestop Mortar mixes with water to form a non-shrinking, high yield mortar that may be applied by pouring, pumping, or troweling. Its low density and light weight means that less forming, as well as less forming support, is required. Its low density also makes re-penetration for retrofitting a simple task. SpecSeal® Firestop Mortar is designed to dry quickly and will not crack or spall due to freezing or changes in temperature.
