Gorilla Waterproof Coat & Seal is a liquid rubber coating that stops leaks fast. Brush, roll, trowel or pour it on and the self-levelling formula flows into small cracks and gaps, curing to a flexible, rubberised, 100% waterproof seal that keeps out water, air and moisture. It even works on wet surfaces, so you can tackle a leak without waiting for a dry day.
Why choose Gorilla Coat & Seal?
- 100% waterproof for indoor and outdoor use
- Works on wet or dry surfaces
- Flexible: stays crack-free and moves with the surface
- UV resistant for outdoor jobs
- Self-levelling: fills small cracks and gaps up to 6mm
- Paintable once fully cured
- Low odour
- The large 946ml tin is ideal for bigger repairs
Use it to seal leaks in
- Roofs, flat roofs and conservatory roofs
- Gutters and downpipes
- Drainage pipes (not pipes under pressure)
- Windows and uPVC
- Chimneys (not for flashing)
- Caravans (small gaps, cracks and tears, away from the engine and exhaust)
How to use
- Stir for 30 seconds before use.
- Brush, roll, trowel or pour onto the leak. Apply between 10°C and 48°C.
- Wipe away any excess straight away with a dry cloth.
- Let it cure fully (24–48 hours). For bigger leaks, apply more coats, letting each one cure first.
- Clean tools with mineral spirits.
Tip: wear gloves, as it's difficult to remove once cured. For a watertight seal, apply to non-porous surfaces. Not for gaps larger than 6mm.
