🔥 Seal the heat, own the hearth! 🔥
DAP High Heat Fire Resistant Mortar is a black silicate cement paste designed for interior wood-frame construction and fireplace repairs. It meets ASTM E136 standards for non-combustibility, withstands temperatures up to 2000°F, and sets rock hard when fired. This waterproof, low-odor sealant is easy to apply, cleans up with water, and can be painted after curing, making it the go-to solution for firebrick patching and firestop sealing.
