Detailed Description:
Gorilla Waterproof Coat & Seal Spray is made for precise, localised repairs where a clean, uniform waterproof coating is required. Its flexible, rubberised formula fills fine cracks and gaps while creating a strong, long-lasting protective layer. The spray format allows easy access to tight or awkward areas such as gutter joints or narrow roof gaps.
Once cured, it becomes fully waterproof, weather-resistant and temperature-tolerant. It is formulated for small-area sealing and is not intended for coating large surfaces.
