FAQs

Can I use these boards for interior walls?

While technically possible, these boards are specifically pressure-treated for outdoor use and may have a distinct odor or chemical residue not ideal for interior living spaces.

Do I need to prime the boards before painting?

Yes, once the boards have dried out sufficiently after installation, apply a high-quality exterior primer followed by outdoor wood paint.

What is the total coverage of one board?

Each board covers approximately 0.36 square meters.

Can these be installed directly onto brickwork?

No, they should always be fixed to a timber batten framework to allow for airflow and prevent moisture buildup between the cladding and the masonry.

What tools are required for installation?

You will need a circular saw or hand saw, a drill, a spirit level, measuring tape, and galvanized nails or screws.

How long does the pressure treatment last?

While the treatment is designed for long-term decay resistance, environmental factors vary, so it is recommended to maintain the boards with a sealant annually.

Troubleshooting

Boards are not clicking together properly

Check the groove for debris or wood shavings and ensure the board is perfectly level before applying pressure.

Timber appears slightly damp or green on the surface

This is a normal characteristic of the pressure treatment process; allow the boards to air out in a dry, ventilated area before installation.

Gaps appearing after installation

Ensure the boards were allowed to acclimatize to the outdoor environment for 24-48 hours before fitting to account for natural expansion and contraction.

Pros and Cons

Pros

  • Interlocking T&G design creates a strong, weather-resistant barrier
  • Pressure treated to resist rot and moisture damage
  • Suitable for both horizontal and vertical installation
  • Lightweight and manageable for solo installation
  • Provides a clean, traditional aesthetic for garden buildings

Cons

  • Requires professional cutting tools for precise custom fits
  • Pressure treatment does not eliminate the need for periodic maintenance
  • Requires external staining or painting for specific color preferences

Setup, Compatibility & Care

Before installation, ensure your timber framework is level and square, as this directly affects the alignment of the cladding. Use galvanized nails or screws to prevent corrosion over time. When cutting, always treat exposed end-grain with a high-quality timber preservative to maintain the integrity of the pressure treatment. While the timber is pre-treated for decay resistance, we recommend applying a water-repellent wood stain or exterior-grade paint within the first season to enhance UV protection and prevent the wood from silvering due to sun exposure.
