Colours

High Pressure – Wolmanit® CX-10: available in ‘Green’ or ‘Brown’.

Wolmanit® CX-treated timber normally has a green colour (on freshly sawn softwoods). This is due to copper compounds in the treatment with the final colour being a result of permanent chemical reactions in the wood fibres. The initial ‘fresh’ green colour fades over 3-6 months eventually turning a golden brown (honey) before finally weathering under the effects of UV light so that after 12 – 24 months the wood surface will ‘silver’ as normal (this does not affect the performance of the preservative).

Wolmanit® CX-treated timber is also available in a brown finish. The Wolmanit® ProColour Brown additives will give the wood an even appearance with good weathering properties (under normal conditions of exposure lasting 12-24 months before fading to silver as above). Other colour finishes may be available, please ask for further details.

Low Pressure – Wolsit KD20: available in clear or pale yellow

Wolsit® KD20-treated timbers are normally intended for building projects and a yellow marker dye is used to provide evidence of treatment on construction sites. This fades naturally on exposure to UV light within 4 – 8 weeks depending on the time of year. Wood can be painted or stained as normal but if a clear varnish is being used please be aware that the yellow dye may show through.
