SiOO:X finish to timber cladding
We are often asked about cladding finishes and protecting the wood. It is almost impossible to maintain the “orange” tone of wood externally as the sun bleaches the colour from wood (and almost every other material). In cities it is often difficult to prevent a dark grey staining caused by pollution. We have moved to recommending the SiOO:X finish to timber cladding – the image here showing the change that occurs between 1 month and 12 months.
The effect is best decribed as a form of bleaching, a natural whitewash, which protects the wood.
