The GD Silicone Marine 280ml is a versatile silicone sealant designed for sealing and bonding applications where a flexible, durable seal is required. Supplied in a convenient 280ml cartridge, this marine silicone is suitable for compatible surfaces exposed to moisture and demanding environmental conditions, making it useful for marine-related, household, maintenance, and general sealing applications.
Its flexible silicone formulation helps accommodate normal movement between compatible materials while creating a neat seal around joints, gaps, and connection points. Always confirm the specific water-resistance and application ratings on the product packaging before use.
GD Marine Silicone 280ml
GD Silicone Marine is supplied in a 280ml cartridge for controlled application with a compatible sealant gun.
Marine-type silicone is intended for applications where resistance to moisture and environmental exposure is important. Depending on the manufacturer’s specifications, it may be suitable for sealing around compatible glass, metal, ceramic, and other building or marine-related surfaces.
The flexible cured seal makes silicone useful for joints where minor movement may occur without requiring a completely rigid connection.
Suitable for Moisture-Exposed Applications
The GD Marine Silicone can be used for suitable sealing applications where exposure to water or moisture is expected.
Potential applications may include:
- Marine-related sealing
- Boats and watercraft maintenance
- Glass joints
- Metal joints
- Bathroom fixtures
- Kitchen fixtures
- General waterproof sealing
- Maintenance and repair work
- Joints and gaps
- Compatible building materials
For permanently submerged applications or specialised marine installations, verify the manufacturer’s suitability specifications before use.
Flexible Sealing Performance
Silicone remains flexible after curing, allowing it to accommodate minor movement between compatible surfaces.
This makes it useful for joints where materials may experience normal expansion, contraction, vibration, or movement.
Correct surface preparation and application are important for achieving effective adhesion and sealing performance.

Application Guidelines
Ensure all surfaces are clean, dry, and free from dust, grease, oil, loose material, and old sealant before application.
Cut the nozzle according to the required bead size and place the cartridge into a compatible sealant gun. Apply a continuous, even bead along the joint and smooth the silicone before it begins to skin.
Allow the silicone to cure completely according to the manufacturer’s instructions before exposing the sealed area to water, moisture, cleaning products, or regular use.
Important Information
Marine silicone formulations can vary considerably between manufacturers. Before application, check the packaging for the product’s surface compatibility, curing time, temperature range, water resistance, UV resistance, adhesion requirements, and application limitations.
For aquariums, potable-water systems, permanently submerged joints, structural glazing, or other specialised applications, only use the product if the manufacturer specifically confirms suitability.
