Our black Fireplace Mortar comes in a convenient 10.3 fluid ounce caulking cartridge that covers up to 99 feet! It's perfect for filling in those little holes, cracks, and imperfections that tend to occur between the bricks and masonry on your fireplace. This heat-resistant mortar can be fired immediately after application. Once properly cured at 1200°F, it will withstand temperatures up to 2000°F and will be as hard as the surrounding firebrick. While the black color will match many fireplaces, this mortar can be painted any shade after curing to ensure a perfect match. We recommend using only on areas 1/8" or smaller. Meets ASTM E-136 and E72 non-combustibility standards for all your fireplace mortar repairs.
