💥 Seal it fast, seal it strong — never let leaks win!
United Gilsonite Lab 00917 is a 4-pound fast-setting cement that hardens in 3-5 minutes, designed to stop water leaks even under pressure. It bonds metal to stone without needing a top coat, expands as it dries to lock in place, and works indoors or outdoors to patch cracks and seal masonry joints reliably.
