FAQs

What is the coverage of a single board?

Each board provides 0.36m2 of coverage.

Can I paint this cladding?

Yes, but ensure the timber is completely dry and use a breathable exterior wood paint or stain.

Do I need to treat the wood after purchase?

While it is pressure-treated, applying an additional protective coating can further extend the life and appearance of the cladding.

Can this be used for internal walls?

Yes, it is suitable for interior cladding as long as the wood is allowed to acclimate to the room's temperature and humidity.

What tools are needed for installation?

You will need a saw, a drill/driver, a level, a hammer, and appropriate exterior-grade fixings.

Is the cladding rot-proof?

It is highly resistant to rot and decay due to pressure treatment, but no timber is entirely immune to rot if exposed to standing water for long periods.

Troubleshooting

Boards are not fitting together smoothly

Check that the groove is free of debris or paint; gently tap the tongue into the groove with a rubber mallet.

Visible gaps appearing between boards

This is often due to natural timber shrinkage; ensure the wood is properly acclimated to the environment before installation and use a high-quality exterior sealant if necessary.

Pros and Cons

Setup, Compatibility & Care

Storage: Keep boards in a dry, well-ventilated area off the ground before installation to prevent warping.
Preparation: Ensure the support structure is level and plumb.
Cutting: Use a fine-toothed saw for clean cuts; always treat cut ends with a high-quality wood preservative to maintain the integrity of the pressure treatment.
Fixing: Use two fixings per batten for boards 120mm wide to prevent cupping.
Maintenance: Inspect the cladding annually. Apply a fresh coat of wood stain, oil, or preservative every 2-3 years to combat UV damage and maintain moisture resistance.
