SiOO:X

SiOO:X Wood Protection eliminates differential weathering, meaning you can achieve a consistently weathered look without the wait. Made from natural and non-toxic ingredients, SiOO:X repels moisture, forming a natural protective barrier to timber cladding.

Consistent weathered finish

Timber, when left uncoated and exposed to the elements, will eventually weather to a silver-grey colour. How quickly and evenly timber weathers is dependent on a variety of factors, including location, aspect and building design. Timber which is sheltered from the elements will take longer to weather, and may result in an uneven or patchy appearance over time. This can take years to even out and in some cases the timber may never weather evenly. SiOO:X eliminates this problem, providing a consistent weathered tone in weeks.

SiOO:X colours

SiOO:X results in a beautifully even façade, with a consistently weathered appearance. It is available in Original (a clear coating) or in pigmented Light Grey and Mid Grey options. A rapid curing process begins upon application; any initial patchiness will fade out over a period of 10-16 weeks, however, Light Grey and Mid Grey will give more immediate colour to the timber. After 2-3 years, the timber is fully cured and a final colour is reached. The result is a consistent weathered tone, achieved years faster than with natural weathering.
