Geocel Marine Grade Silicone Rubber Sealant – Trade Box of 12 (310ml, Clear, Black, White)

Ensure superior waterproof protection for your marine and recreational vehicles with Geocel Marine Grade Silicone Rubber Sealant, available in a Trade Box of 12. This high-performance sealant is engineered to meet the demanding needs of water-exposed environments such as boats, yachts, caravans, and motorhomes.

This makes it ideal for sealing joints, deck fittings, windows, roof vents, and other exterior fixtures that require long-term durability.

The sealant’s exceptional versatility allows it to bond effectively to a wide range of materials, including fiberglass, metal, plastic, and glass, making it the perfect solution for both professional and DIY projects. Available in clear, black, and white, it offers a neat and professional finish, blending seamlessly with different surfaces and colours. Whether you are building, repairing, or maintaining marine vessels, motorhomes, or caravans, this sealant delivers industry-leading performance to prevent leaks, corrosion, and environmental damage. The Trade Box of 12 provides cost-effective bulk pricing, ensuring contractors and professionals have a reliable stock supply for multiple installations.

Questions and answers:

Geocel Marine Silicone Rubber Sealant FAQs?

• What specific features make this sealant ideal for marine use?

This sealant is formulated to handle continuous exposure to water, UV rays, and salt spray, which are common in marine environments. Its waterproof properties prevent leaks, while its high elasticity allows it to withstand the constant movement and vibrations that occur on boats. Additionally, it maintains adhesion on surfaces like fiberglass and metal, even under extreme conditions.

• Which types of materials can this sealant bond to, and how does it perform on each?

Fiberglass: Creates a strong, flexible bond that resists cracking under stress and movement.

Metal: Bonds without corroding or staining, making it ideal for marine-grade fixtures.

Plastic and PVC: Adheres effectively without compromising structural integrity.

Glass: Provides a watertight seal for windows and hatches, maintaining clarity and durability over time.

• How long should I wait before exposing the cured sealant to water and physical stress?

The sealant skins over in approximately 10 minutes, and fully cures time 3mm per 24 hours. For optimal performance, it's best to allow full curing before subjecting the sealant to high water pressure or mechanical stress. Factors such as temperature and humidity can influence the curing process, so in colder or more humid conditions, additional curing time may be required.

• Can this sealant withstand outdoor weather conditions on caravans and motorhomes?

Yes, this sealant is designed to endure extreme outdoor conditions. Its UV resistance prevents degradation from prolonged sun exposure, while its waterproof properties stop moisture penetration at seams, joints, and window fittings. It also performs well in fluctuating temperatures, preventing cracking or loss of adhesion in both hot and cold climates.

• How do I choose between the available colours for different applications?

Clear: Best for areas where a discreet finish is needed, such as around glass windows or transparent components.

Black: Ideal for sealing dark surfaces, trim edges, or areas where a contrasting finish could detract from the aesthetics.

White: Commonly used on bright or light-coloured surfaces to maintain a uniform, clean appearance. Selecting the right colour ensures the sealant blends seamlessly with the surrounding materials.
