Metacaulk Fire Rated Mortar

The Metacaulk Fire Rated Mortar is a fire-rated, load-bearing mortar designed to economically firestop large openings for through-penetrations in fire-rated walls and floors. It can be used with power cables, fiber optic cables, telephone cables, and other approved penetrations.

Metacaulk Fire Rated Mortar is a rapid-hardening gypsum/cement compound that provides an excellent combination of workability, strength, and fire resistance. When mixed with clean water to the proper consistency, it forms a rigid, gas-tight, fire-resistant seal that helps maintain the integrity of rated assemblies.
