Preparation of you timber cladding

ONSITE STORAGE

It is recommended to keep the packs intact and wrapped in plastic as they were delivered, out of the elements until the cladding is ready to be installed. This can help prevent any movement of the boards after being machined.

This may help accuracy and straightness, making the installation process considerably easier.

MOISTURE

Although the timber cladding has been dried to a moisture content suitable for external applications, it will still take on moisture from rain, air conditions and the ground, causing natural expansion and contraction to occur across the width of the board. As this expected process can affect the ease of installation it is best to keep the product dry, stored at least 50mm above the ground and installed as soon as possible.

If you require your chosen cladding to be used internally, this needs to be specified at the time of order as a different moisture content is required. Internal applications require a lower moisture content than external applications, however in hot and dry areas, cladding may need to be dried specifically to suit. It is always recommended you talk to your supplier to make sure you are getting the right product for your job.

MOVEMENT

Movement is a natural process that causes the timber to expand and contract as moisture is gained and lost within the cells of the timber. This movement cannot be stopped and is expected in all situations. Most claddings have been developed to allow for this movement and needs to be installed correctly to prevent issues caused by movement. Please note there should be a gap around the tongue and groove.

COATING

Fully coating your cladding on all sides before installation can prevent movement and it also helps to protect the cladding while on site. It is recommended to be factory coated in Cutek, or any oil based product. If not factory coated, your cladding needs to be fully coated before installation. Any ripped edges or end trims must be sealed by the same product. All coatings will require recoating and maintenance as per manufacturers recommendations.

PAINT

Using dark colours can cause the timber to absorb heat more than lighter paints and stains. If you are considering using a black or dark stain it is advised that you face fix your cladding as there is more chance your cladding will move over time.
