Why Choose FixTech Fix8 Grey?

Professional Structural Bonding Performance

FixTech Fix8 is formulated to provide strong adhesion while maintaining flexibility after curing.

This makes it particularly useful for suitable applications exposed to vibration, movement and temperature changes.

Designed for Marine Environments

Boats and marine equipment are regularly exposed to moisture, saltwater spray, UV radiation and changing weather conditions.

Fix8's durable silicone formulation makes it a practical choice for compatible marine bonding and sealing applications.

Long-Lasting Flexibility

Unlike rigid adhesives, FixTech Fix8 cures to a flexible rubber seal that helps accommodate movement and thermal expansion.

This makes it well suited to joints and fittings where some movement is expected.

Professional Grey Finish

The grey formulation provides a subtle, professional appearance that complements aluminium boats, metal fixtures, caravan panels and other grey or metallic surfaces.

Versatile Multi-Surface Adhesion

FixTech Fix8 is suitable for many common materials used in boats, caravans and general construction, providing a versatile solution for a range of maintenance tasks.

Application Instructions

1. Prepare the Surface: Ensure all surfaces are sound, clean, dry and free from dust, grease, oil and loose material.

2. Check Compatibility: Test adhesion and material compatibility before proceeding with the full application.

3. Prepare the Cartridge: Cut the nozzle to the required bead size and insert into a suitable caulking gun.

4. Apply the Silicone: Apply a continuous, even bead to the prepared joint or surface.

5. Position Components: Assemble or position components as required, using temporary support where necessary.

6. Tool the Sealant: Smooth the bead before skin formation to achieve a neat, professional finish.

7. Allow to Cure: Protect the application and allow adequate curing time before exposing it to operational loads or service conditions.

Curing times depend on sealant thickness, temperature and humidity. Follow the manufacturer's current application instructions.
