Gorilla Window & Door Frame Silicone Sealant White 295ml

Gorilla Window & Door Frame Silicone Sealant White 295ml

Protect your home against water penetration and changing weather conditions with Gorilla Window & Door Frame Silicone Sealant White 295ml.

Specifically developed for sealing around windows, door frames and exterior joints, this high-performance silicone creates a completely waterproof barrier that helps prevent moisture from entering gaps around compatible building materials.

Its flexible formulation is designed to accommodate normal movement around frames, while its white finish provides a neat, professional-looking seal.

Whether you're fitting new windows, replacing deteriorating sealant or completing general home maintenance, Gorilla Window & Door Frame Silicone Sealant combines weather resistance, flexibility and convenient application.

100% Waterproof Protection for Windows and Doors

Gaps around window and door frames can allow rainwater and moisture to penetrate surrounding areas.

Over time, failed or deteriorating seals may contribute to damp patches, staining and damage around internal finishes.

Gorilla Window & Door Frame Silicone Sealant creates a waterproof barrier when correctly applied to compatible surfaces, helping protect vulnerable joints against water ingress.

Its 100% silicone formulation remains flexible once cured, making it suitable for frame joints where minor movement can occur.

For homeowners and tradespeople looking for dependable waterproof sealing around doors and windows, this product provides a practical solution.

Rain Ready in Just 30 Minutes

Outdoor sealing work can be challenging when weather conditions are unpredictable.

Gorilla Window & Door Frame Silicone Sealant features a fast-setting formula that can be exposed to rain or water after approximately 30 minutes under the manufacturer's specified conditions.

This is particularly useful when completing exterior repairs or installations where waiting for an extended dry period may be inconvenient.

The 30-minute claim applies to a 5mm bead at 21°C and 50% relative humidity.

Although the sealant can tolerate water exposure after this period, it requires approximately 24 hours to achieve a full cure under suitable conditions.

Lower temperatures, reduced humidity and larger bead sizes can increase curing time.

UV-Resistant Formula for Outdoor Applications

Exterior window and door seals are regularly exposed to sunlight, rain and changing temperatures.

Gorilla Window & Door Frame Silicone Sealant is formulated to resist ultraviolet exposure, helping maintain the appearance and performance of the cured seal.

The manufacturer describes the formula as resistant to yellowing, making it particularly useful for maintaining a clean white finish around frames.

As with all exterior products, the appearance of the sealant may be affected by prolonged environmental exposure, so correct application and routine maintenance remain important.

Mould-Resistant for a Cleaner Finish

Moisture can collect around window frames, door surrounds and other joints, creating conditions where mould and mildew may develop.

Gorilla Window & Door Frame Silicone Sealant contains an anti-mould formula designed to help resist mould and mildew growth on the cured sealant.

This makes it useful for areas exposed to condensation and moisture.

The manufacturer advises cleaning the cured sealant regularly to maintain its mould-resistant performance.

Alongside effective sealing, adequate ventilation and moisture control can help reduce conditions that encourage mould growth.

Flexible Silicone That Resists Shrinking and Cracking

Windows and doors can experience small amounts of movement as materials expand and contract with temperature changes.

Rigid sealants may crack when this movement occurs, potentially allowing moisture to penetrate the joint.

Gorilla Window & Door Frame Silicone Sealant is made from 100% silicone, providing a flexible seal that accommodates normal movement once cured.

The formula is designed to resist shrinking, cracking and splitting, helping maintain a durable barrier around compatible frames and joints.

This flexibility makes it particularly useful for exterior sealing applications exposed to changing weather conditions.

Suitable for Interior and Exterior Sealing

Although designed primarily for windows and door frames, Gorilla Window & Door Frame Silicone Sealant can also be used for compatible interior and exterior sealing applications.

The manufacturer identifies windows, doors, frames and façades among its intended uses.

It is suitable for various compatible building materials, including uPVC, glass, ceramic, suitable metals and other approved surfaces.

Always confirm compatibility before application, particularly when working with specialist finishes or materials sensitive to corrosion.

The sealant must not be used on brick, cementitious materials, wet or frozen surfaces, or for underwater applications.

Clean White Finish

The white colour provides a neat, consistent appearance around white window frames, door surrounds and other compatible building components.

It is particularly suitable where a visible sealant bead needs to blend with white frames and trims.

The smooth silicone finish can be shaped immediately after application using a suitable sealant finishing tool.

Because the cured sealant is not paintable, the white finish should be chosen where it complements the surrounding materials without requiring additional decoration.

Easy Application with a Standard Sealant Gun

Supplied in a 295ml cartridge, Gorilla Window & Door Frame Silicone Sealant is designed for use with a standard cartridge gun.

The nozzle can be trimmed to the required bead size, allowing controlled application along joints and frame edges.

For the best results, surfaces should be clean, dry and free from grease, dirt, oil and old sealant.

Apply a continuous bead, pushing the sealant ahead of the nozzle, then smooth immediately before a skin begins to form.

A single cartridge provides approximately 14 metres of coverage when applying a 5mm bead.

Reliable Sealing for Home Maintenance and Renovation

Whether you're installing replacement windows, sealing around a new door frame or refreshing weathered joints, Gorilla Window & Door Frame Silicone Sealant White 295ml offers dependable waterproof protection.

Its combination of UV resistance, mould resistance, flexibility and rapid rain readiness makes it particularly useful for exterior maintenance.
