The sealant spreads into the crack and sets into a clear, flexible barrier that blocks water on contact
This waterproof sealant flows into cracks, gaps and joins on contact, then sets into a flexible, water-blocking layer. It comes in a tube and is applied by hand or with a basic applicator, spreading evenly over uneven surfaces before it sets. Once set, it forms a thin, water-tight seal that stays flexible rather than cracking or peeling with movement. It's available in three finishes — transparent, white and black — so the repair can blend into the surrounding surface.
Why is this Waterproof Sealant perfect for you?
- Sets on contact: Stops water getting further into the gap while you're still working, so a repair started in minutes keeps moisture out straight away.
- Non-toxic formula: Contains no harsh chemicals, so it can be used in bathrooms, kitchens and other lived-in rooms without strong fumes building up.
- Bonds to multiple materials: Sticks to metal, ceramic, plastic and fabric alike, so one tube covers tiles, pipework, gutters and outdoor gear.
- Flexible once set: Stays pliable rather than brittle, so the seal keeps working through everyday movement and temperature changes without cracking.
