Gorilla Waterproof Coat & Seal Clear 473ml Liquid Sealant

When a leak is confined to a crack or small gap, a targeted seal can be more practical than treating a whole surface. Gorilla Waterproof Coat & Seal is a clear liquid sealant for localised repairs, helping to keep water, air and moisture out.

Its flexible, weatherproof formula is designed for indoor and outdoor use. The self-levelling liquid spreads across small gaps to form a watertight seal, so it can help protect areas exposed to the elements.

Use it on suitable surfaces such as roof tiles, brick, wood, metal, concrete, stone, rubber and plastics. It is also intended for tasks around gutters, downpipes, windows and uPVC, external chimneys, and small caravan repairs.

Tech summary

• Product: Clear liquid sealant
• Size: 473ml
• Application: Brush, roll or pour
• Use: Indoor and outdoor sealing of small cracks and gaps
• Suitable surfaces: Roof tiles, brick, wood, metal, concrete, stone, rubber and plastics
• Formula: Flexible, weatherproof and self-levelling

The clear finish suits repairs where a coloured coating is not wanted, while the self-levelling formula helps the liquid cover small cracks and gaps. Rather than coating a large area, this product is intended for specific points that need sealing. Its range of listed surfaces makes it useful for jobs around the home and garden, from a roof tile or gutter to a small repair on a caravan.

Practical tips

Choose a localised repair where the product can be applied directly to the crack or gap. The liquid can be brushed, rolled or poured, allowing you to use the application method that best suits the area. For example, a small gap around an external chimney or window can be treated directly, while a gutter or downpipe repair can be approached as a focused sealing task.

The formula is intended for roof tiles, brick, wood, metal, concrete, stone, rubber and plastics, it may not work with every type of plastic or rubber. Use it for small repairs rather than coating large surface areas. It is not intended for flashing applications, pipes under pressure or use inside a firebox. Keeping these application points in mind helps match the sealant to the repair at hand.

How to use it

Apply the liquid by brushing, rolling or pouring it over the small crack or gap to be sealed. Its self-levelling action helps it spread over the repair area, and the flexible, weatherproof formula is designed to protect against water, air and moisture indoors or outdoors. This makes it a practical choice for targeted sealing jobs on suitable surfaces, including gutters, downpipes and roofing, as well as small caravan repairs.

Is it worth it?

For repairs that need a clear, flexible seal rather than a treatment across a broad surface, Gorilla Waterproof Coat & Seal offers a straightforward way to address small leaks and gaps. The 473ml liquid can be applied with a brush, roller or by pouring, and its self-levelling formula is designed to cover the repair area smoothly. With indoor and outdoor use and a range of suitable materials, it can serve several common sealing tasks around a property. It makes sense if you need a targeted sealant for a small repair on a compatible surface, particularly where weatherproof protection is important.
