Geocel Frame Silicone Sealant Anthracite 300ml

Geocel Frame Silicone Sealant Anthracite 300ml is a professional-grade exterior silicone sealant specifically developed for sealing the perimeter joints around window and door frames.

Powered by Dow technology, this premium-grade, low-modulus neutral-cure silicone provides excellent adhesion to a wide range of compatible building materials, including PVCu, wood and metal. It is particularly suitable for creating a durable, weather-resistant seal where window and door frames meet surrounding masonry or other appropriate building surfaces.

Its anthracite finish makes it an excellent choice for dark grey windows, anthracite PVCu doors and contemporary exterior frames. Rather than using a contrasting white sealant, the anthracite colour helps achieve a coordinated appearance around suitable window and door installations.

Exterior frame joints are exposed to rain, sunlight, temperature changes and everyday building movement. Geocel Frame Silicone is formulated to withstand these conditions, providing a permanently weatherproof seal that helps protect suitable joints against moisture penetration and draughts.

The highly flexible formulation accommodates normal expansion and contraction around window and door frames. This is particularly important where different materials meet, as PVCu, timber, metal and masonry can respond differently to changing temperatures.

Geocel Frame Silicone is also UV-resistant, helping it withstand prolonged sunlight exposure without compromising its sealing performance. Its durable neutral-cure formulation is designed not to shrink or crack, supporting a long-lasting finish around exterior frames.

Whether you're fitting new anthracite grey windows, resealing an existing exterior door or carrying out general property maintenance, Geocel Frame Silicone Sealant Anthracite 300ml offers a specialist solution for creating a flexible, weatherproof perimeter seal.

Best Uses

  • Exterior perimeter sealing around compatible PVCu window frames.

  • Sealing around anthracite grey windows and doors.

  • Weatherproofing joints between window frames and suitable masonry.

  • Sealing exterior wooden window and door frames.

  • Sealing compatible metal and aluminium frame installations.

  • Replacing deteriorated exterior silicone around window frames.

  • Sealing suitable joints around external door frames.

  • Exterior property maintenance requiring a flexible, weather-resistant seal.

  • Applications where a dark anthracite finish is preferred.

How to Use

  1. Ensure all surfaces, gaps and joints are clean, dry and free from dust, dirt, grease and loose material.

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

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

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

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

  6. Apply a continuous, even bead along the perimeter joint, ensuring good contact with the surfaces being sealed.

  7. Smooth the silicone using an appropriate sealant finishing tool to achieve a neat, consistent finish.

  8. Allow the sealant to cure according to the manufacturer's instructions before subjecting the joint to demanding conditions.

The manufacturer specifies an approximate skin-over time of 20 minutes and a cure rate of approximately 3mm per 24 hours at 23°C and 50% relative humidity. Actual curing times depend on joint dimensions and environmental conditions.
