Geocel Frame Silicone Sealant Brown 300ml

Geocel Frame Silicone Sealant Brown 300ml

Geocel Frame Silicone Sealant Brown 300ml is a specialist exterior silicone sealant designed to create durable, weatherproof perimeter joints around window and door frames.

Developed using premium-grade silicone powered by Dow technology, its neutral-cure formulation provides excellent adhesion to a range of compatible materials, including PVCu, wood and metal.

The brown finish is particularly suited to brown PVCu windows, timber-effect exterior doors and compatible wooden frames where a colour-coordinated seal is preferred. It helps create a neat appearance without the strong contrast of a white or clear sealant.

Exterior window and door joints are regularly exposed to rain, sunlight and temperature changes. Over time, these conditions can place stress on sealing materials, particularly where different building materials meet.

Geocel Frame Silicone is formulated to provide permanent weatherproofing, helping protect suitable perimeter joints against moisture penetration while maintaining a flexible connection between the frame and surrounding building materials.

Its highly flexible composition accommodates normal movement caused by expansion and contraction. This is especially important around window and door installations, where timber, PVCu, metal and masonry can respond differently to changing temperatures.

The silicone is also UV-resistant and highly durable, making it suitable for exposed exterior applications. Its neutral-cure formulation is designed not to shrink or crack, helping maintain a reliable seal over time.

Whether you're installing new brown PVCu windows, resealing an existing timber-effect door or carrying out routine exterior maintenance, Geocel Frame Silicone Sealant Brown 300ml offers a practical solution for achieving a flexible, weather-resistant finish.

How to Use

2. Remove deteriorated or incompatible existing sealant and prepare the joint according to the manufacturer's instructions.

3. Remove the nozzle and open the end of the cartridge.

4. Reattach the nozzle and cut its tip to the required bead width.

5. Insert the 300ml cartridge into a suitable sealant gun.
