Seal Cracks Instantly. Waterproof. Permanent.
A heavy-duty waterproof concrete sealant that fills and seals cracks, gaps, and leaks in walls, floors, roofs, and pipes — instantly and permanently. Pack of 2.
The Problem With Cracks & Leaks at Home
Cracks in walls, floors, and roofs allow water seepage that leads to dampness, mould, structural damage, and expensive repairs. Most sealants take hours to cure, shrink after drying, or fail to bond properly to wet or damp surfaces. Calling a contractor for minor crack repairs is expensive and time-consuming. There's rarely a fast, reliable DIY solution that works on wet surfaces and lasts permanently.
- Water seeping through cracks causing dampness and mould
- Sealants that shrink, crack, or fail on damp surfaces
- Expensive contractor costs for minor crack repairs
- Slow-curing products that can't be used in wet conditions
