Big Size 750g • Roof & Leak Repair
Stop Leaks Today — Seal It Once, Stay Dry Every Season
A strong, flexible waterproof silicone sealant that grips metal, glass, ceramic, wood and plastic — and holds from -50°C to 150°C.
That Small Leak Won't Stay Small
A drip from the roof, a damp patch on the wall, a seeping tank joint — ignore it and it turns into peeling paint, fungus, rusted metal and an expensive repair bill. Calling a plumber or waterproofing contractor for every small crack costs time and money.
- ❌ Water seeping through roof cracks during monsoon
- ❌ Leaking pipe joints, tank edges and bathroom fittings
- ❌ Gaps around windows, doors and sheets letting in rain
- ❌ Cheap sealants that crack and peel after a few weeks
The Fix: One Tube, Sealed for the Long Run
This waterproof silicone sealant goes on smoothly, fills cracks and joints completely, and cures into a flexible rubber-like barrier. Because it stays flexible, it moves with heat, cold and vibration instead of cracking — so the leak stays sealed.
Why Homeowners Choose This Sealant
💧 Truly Waterproof
Forms a tight, water-resistant seal that keeps rain and seepage out of roofs, walls and joints.
🔗 Strong Adhesion
Grips firmly to multiple surfaces so the seal doesn't lift, peel or separate.
🧘 Stays Flexible
Cures into an elastic layer that absorbs movement and vibration instead of cracking.
☀️ All-Weather Tough
Built for harsh sun, heavy rain and cold — indoors or outdoors.
Built to Survive Extreme Weather
From freezing winters to scorching summer rooftops, the seal holds firm across a wide -50°C to 150°C temperature range.
