What makes it Different?
Ordinary sealant hardens, then cracks the first time the surface expands in the heat. SS-9900 Silicone Sealant stays flexible after curing, so it moves with the roof instead of splitting away from it — and it holds that seal from −50°C right through to 150°C. Waterproof, paintable, and it grips almost every building material you will put it on.
One Leak.Two Monsoons.
Small cracks are what ruin ceilings.
Water finds a hairline gap in the terrace, tracks through the slab and shows up as a damp patch three rooms away. Patch the crack properly and the damp never starts.
−50°C to 150°C.Still Sealed.
Built for Indian rooftops and Indian summers.
- Heavy rain, direct sun and humidity — no peeling
- Stays flexible, so it never cracks off the surface
- Seals within minutes of application

Roofs, terraces, water tanks, pipelines, windows, kitchens and expansion joints.
Hear it from a Site Engineer
Most sealants we get on site go hard and crack off the slab by the second summer. This one stays flexible, which is the whole game on a terrace that expands all day and contracts all night.
Grips galvanised sheet and concrete equally well, and the fact that it takes paint afterwards saves us a finishing step.
