All high pressure timber treatment at WJ is performed using BASF-Wolman's market leading Wolmanit® CX-10 to ensure a long lasting and robust finish.
Wolmanit® CX is a liquid wood preservative based on copper and organic biocides. Used extensively in the UK and mainland Europe, it protects timber from all forms of insects, wood destroying fungi and other biological decay hazards. Wolmanit® CX is water-based and doesn’t use chromium or arsenic so is a low-hazard preservative, safe to handle and with a low environmental impact. In short, Wolmanit® CX is an extremely comprehensive and effective preservative treatment for timber that is kind to the environment and continues to retain its market leading position across Europe.
Treating timber in an industrial pressure timber treatment tank allows for a thorough and professional result every time; the timber preservative penetrating deeply through the wood to provide long lasting protection. We have high pressure timber treatment tanks in both Hull and Rochester to treat your timber using this well established and comprehensive process, offering you our standard green treatment in addition to a brown treatment at Hull.
Treated wood offers excellent durability and mould resistance for almost all end uses and is a popular process for all manner of products such as fence posts, decking, sleepers and fence panels.
A note about Wolmanit® CX-10 brown treatment
At our treatment facility in Hull, we can offer you both Wolmanit® CX-10 brown treatment in addition to our standard green timber treatment. The specification of treatment is exactly the same for both (Wolmanit® CX-10), the only difference being the presentation of the finished product.
Our brown treatment has a brown pigment dye added and some customers prefer to use this. Giving the timber a rich brown colour after treatment, it’s important to note that this might not be an even colour across the wood.
Sap and heartwood have different cell structures and this can cause the dye molecules to be absorbed at different rates. You could compare this to the absorption rates of sponge compared to concrete; it’s a very similar scenario. This can and does lead to a patchy appearance on the surface of the treated timber, especially at the boundaries of sapwood and heartwood.
Most evident immediately after treatment, the colour tends to become more uniform as the timber gradually dries out and is exposed to UV light. In fact with time, the timber might well revert back to the colour of the base treatment. This is perfectly normal and entirely due to the natural characteristics of timber.
