There is also a tendency to get salty deposits on the surface these can be washed off with water. We recommend washing the cladding with running water to accelerate the weathering and to remove any excess treatment prior to installation this can be done using a garden hose pipe or a bucket and cloth.

Washing the cladding avoids excess treatment running off and encountering other materials which may cause reaction, especially metals, aluminium, tiles, concrete, grass, lawns etc. It is best to mask areas such as glass, any plinths, skirtings etc. If treatment runs onto other surfaces this cannot be washed off or cleaned off.

The treatment is applied in a factory environment, there is no need to reapply any further treatment to make it more grey or uniform – you need to allow the reaction to take place; this starts to even out approximately 1 week onwards from exposure.

If you want to achieve a more grey finish quicker you may resort to touching up onsite by brush with the old look treatment as the last resort but the benefits of this are minimal. It should be noted that wood is a natural product and will still show some variations in colour or tone after treatment. There may be variations in batches and different elevations. The colours can range from grey to a blueish green to black tones.

You need to fix the SertiWOOD® pre-aged weathered treated wood with stainless steel fixings, making sure that the wood is not in contact with any other metals, materials or there is no residue runoff onto other materials from the treatment.

Please contact us if you need any help with the selection or specification of the SertiWOOD® Old Look pre-weathered silvery grey finish for your next project or download the cladding and decking BIM OBJECTS. We keep some products pre-treated for prompt delivery to site.
