Gorilla Waterproof Coat & Seal Spray Black 450ml is a flexible, rubberised waterproof coating designed to seal out water, air and moisture while covering small gaps and cracks.

The convenient aerosol format features a controlled spray-pattern nozzle that provides a clean, even coat across compatible surfaces, making it ideal for repairs where a brush or roller would be difficult or inconvenient to use.

Once applied, the self-levelling formula smoothly covers small cracks and gaps, creating a continuous watertight seal over the repair area.

When dry, Gorilla Waterproof Coat & Seal Spray is paintable, temperature resistant and UV resistant, helping provide a durable, long-lasting repair suitable for demanding applications.

The black finish makes it particularly useful on dark surfaces and projects where a black protective coating is preferred.

For anyone searching for Gorilla waterproof spray, waterproof sealant spray, liquid rubber spray, leak repair spray, black waterproof coating, rubberised sealant or waterproof crack sealer, Gorilla Waterproof Coat & Seal Spray provides an easy way to create a flexible waterproof barrier.

Flexible Rubberised Waterproof Coating

Gorilla Waterproof Coat & Seal Spray creates a flexible rubberised coating over compatible surfaces.

The coating forms a protective barrier designed to prevent water, air and moisture from passing through the treated area.

Its flexible nature makes it particularly useful for repairs where a rigid filler or coating may not be the most practical solution.

Creates a Watertight Seal

Once correctly applied, the coating forms a watertight seal across the repair area.

This makes it useful for suitable applications involving:

• Small leaks

• Cracks

• Gaps

• Joints

• Weather-exposed areas

• Moisture penetration

• General waterproofing repairs

For pressurised systems, structural repairs or other safety-critical applications, use a repair system specifically approved for that purpose.

Waterproof Leak Repair Spray

The aerosol format makes Gorilla Waterproof Coat & Seal particularly convenient for targeted leak repairs.

Rather than manually spreading a liquid coating, the spray allows a protective layer to be applied directly across compatible problem areas.

Multiple passes can help build appropriate coverage according to Gorilla's application instructions.

Controlled Spray Pattern

The applicator nozzle produces a controlled spray pattern, helping direct the waterproof coating where it is required.

This provides several advantages:

• Cleaner application

• More even coverage

• Better control

• Easier access to awkward areas

• Reduced unnecessary application

• Smooth coating across the repair area

Self-Levelling Formula

After application, Gorilla Waterproof Coat & Seal Spray uses a self-levelling formula that helps the coating settle smoothly across the surface.

This allows it to cover minor imperfections, small gaps and cracks while creating a more continuous protective barrier.

Covers Small Gaps

Small openings can allow unwanted water, moisture or air to penetrate a surface.

Gorilla Waterproof Coat & Seal Spray helps cover and seal small gaps, forming a flexible coating over the affected area.

Covers Small Cracks

The self-levelling liquid coating can also cover small cracks, making it useful for suitable maintenance and waterproofing jobs.

For significant, expanding or structural cracks, the underlying cause should be addressed using an appropriate repair method before relying on a surface coating.

Seals Out Water

The rubberised coating provides a barrier designed to seal out water, making it useful for suitable repairs exposed to moisture or wet weather.

Seals Out Air

Gorilla Waterproof Coat & Seal Spray also helps seal unwanted airflow through small gaps and cracks, adding to its versatility as a general sealing product.

Seals Out Moisture

By creating a continuous protective coating, the product helps prevent moisture from passing through the treated area.

This makes it useful for compatible exterior and moisture-exposed applications.

UV Resistant

Outdoor repairs can be exposed to prolonged sunlight.

Gorilla Waterproof Coat & Seal Spray is UV resistant when dried, helping the finished coating withstand exposure to ultraviolet light and supporting longer-lasting exterior repairs.

Temperature Resistant

Once dry, the coating is also temperature resistant, helping it withstand temperature changes that can occur during everyday indoor and outdoor use.

Always follow Gorilla's specified application and service-temperature limits.

Paintable When Dry

Gorilla Waterproof Coat & Seal Spray is paintable once dried, allowing the finished repair to be coordinated with surrounding surfaces where required.

This is particularly useful when the black coating needs to be covered as part of the final decorative finish.

Always ensure the chosen paint is compatible with the cured coating.

Black Waterproof Coating

The spray dries to a black finish, making it particularly suitable for dark surfaces or projects where a black waterproof coating is desirable.

The coloured coating can also make it easier to see where the product has been applied during the repair.

Spray vs Liquid Waterproof Coat & Seal

Gorilla Waterproof Coat & Seal is available in application formats suited to different projects.

Gorilla Waterproof Coat & Seal Spray is particularly useful for:

• Quick targeted applications

• Awkward areas

• Irregular surfaces

• Smaller repairs

• Areas where brushing is difficult

• Controlled aerosol application

Gorilla Waterproof Coat & Seal Liquid is particularly useful for:

• Larger surface areas

• Brush application

• Roller application

• Pouring

• Broad-area waterproof coating

• Projects requiring heavier manual coverage

The best option depends on the size, shape and accessibility of the repair area.

Waterproof Spray vs Patch & Seal Tape

Gorilla Waterproof Coat & Seal Spray and Gorilla Waterproof Patch & Seal Tape both provide waterproof repair options, but they work differently.

The spray coating is particularly useful for covering irregular surfaces, small gaps and multiple fine cracks with a continuous rubberised layer.

Waterproof Patch & Seal Tape may be preferable when a physical tape patch is required over a hole, tear, crack or localised damaged area.

How to Use

• Check that the surface and application are compatible with Gorilla Waterproof Coat & Seal Spray.

• Prepare and clean the surface according to Gorilla's instructions.

• Remove loose dirt, dust, grease, oil and contamination.

• Protect surrounding areas from overspray.

• Shake and prepare the aerosol according to the directions on the can.

• Apply using the controlled spray nozzle.

• Spray an even coating over the repair area.

• Allow the self-levelling formula to settle smoothly.

• Apply additional coats where required according to Gorilla's instructions.

• Allow the coating to dry and cure fully.

• Always follow the manufacturer's complete application, drying, ventilation and safety instructions.
