Why Choose FixTech Fix8 White?

Professional Structural Bonding Performance

FixTech Fix8 is formulated to provide high-strength adhesion while maintaining flexibility after curing.

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

Built for Harsh Marine Environments

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

Fix8's durable silicone formulation makes it an excellent choice for suitable marine bonding and sealing applications.

Long-Lasting Flexibility

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

This helps maintain an effective seal in demanding applications.

Professional Non-Yellowing White Finish

The colourfast white formulation is designed to maintain a clean appearance, making it ideal for visible joints, fittings and finishing applications.

Excellent Multi-Surface Adhesion

FixTech Fix8 bonds to many common materials used in boats, caravans and construction, reducing the need for multiple specialised sealants.

Application Instructions

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

2. Check Compatibility: Test adhesion on the intended substrate before proceeding with the full application.

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

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

5. Position Components: Assemble or position the components as required.

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 time depends on sealant thickness, temperature and humidity. Follow the current FixTech Technical Data Sheet for specific application requirements.
