This mortar is used to make repairs to firebrick and mortar that have been damaged by prolonged heat exposure. The mortar bonds to the firebrick and heat curing makes it as strong as the original firebrick itself. The mortar can also be used to fill in spots where the original mortar or grout between the bricks has crumbled or become damaged. The product meets ASTM E-136 and is available in colors of black, buff, or gray. The package contains a case of twelve 10.3 fluid ounce tubes.
