Waterproof Leak-Proof Sealant

The waterproof formula creates a durable, water-resistant seal that holds up to ongoing moisture exposure — the kind of performance that matters in bathrooms, kitchens and exterior walls where a seal that degrades with water contact is no seal at all. Designed to stop leaks at the source rather than temporarily slow them, and to maintain its integrity over time without cracking, peeling or losing adhesion when wet.

Clear drying means the sealant disappears into the surface once applied — no white residue, no visible patch, no evidence of the repair beyond the leak being fixed. The kind of finish that makes the sealant suitable for use on visible surfaces like bathroom tiles, kitchen splashbacks and exterior brickwork without leaving a cosmetic trace that draws attention to the repair. Apply, let dry, and the surface looks untouched.

Works on tiles, grout, concrete, brick and exterior walls — the kind of surface range that makes a single product genuinely useful across multiple repair jobs around the home rather than a specialist solution for one specific material. Particularly effective on porous surfaces like grout and brick where water infiltration tends to occur, and on tile joints where movement and temperature changes cause existing sealant to crack over time.

The included brush allows the sealant to be applied precisely to the target area — along a grout line, into a crack, around a tile edge — without spreading onto surrounding surfaces or requiring additional tools. The kind of applicator that makes a liquid sealant genuinely easy to use without experience, and one that reduces waste by allowing controlled, targeted application rather than squeezing from a tube and hoping for the right amount. Available in 30g for small repairs or 100g for larger jobs.
