Gorilla Waterproof Coat & Seal liquid rubber coating in Black, 946ml - flexible, self-levelling rubberised formula for roofs, gutters, conservatories, and more

Flexible rubberised protection for leaks and gaps:

Gorilla Waterproof Coat & Seal is a flexible, rubberised liquid coating that seals out water, air, and moisture on a wide range of surfaces. The Self-Levelling formula brushes, rolls, or pours smoothly over small gaps and cracks of up to 6mm, creating a weatherproof, watertight bond that remains flexible and crack-resistant once cured.

Suitable for a wide range of outdoor repair jobs:

This coating is well suited to conservatories, windows, uPVC, caravans, roofing, gutters, drainage pipes, and external chimneys. It is not recommended for pipes under pressure, gaps larger than 6mm, or continuous submersion below the waterline. Surfaces must be non-porous to achieve a full watertight seal.

Cures to a durable, UV-resistant finish:

Apply between 10°C and 48°C for best results. Full cure is reached in 24 to 48 hours, after which the coating withstands temperatures from -40°C to 60°C. Once cured, it is UV-resistant and can be painted over, giving flexibility for colour-matching or finishing work. The 946ml size is suited to larger projects or multiple repairs in a single application session.
