Chimney Masonry Patch Exterior-10.3 Oz. Cartridge
Chimney Masonry Patch is easily applied to broken or missing mortar joints in chimneys or cracks in steps, sills, sidewalks or foundations. It dries to a hard, tough, weather-resistant finish in a natural concrete color. In a few minutes, it skins over and cures in a day or more, depending on thickness of the patch.
