Green copper is frequently used to treat wood when it is at risk from fungal spores and insect attack. This is particularly true where wood is outdoors and subject to the elements. There is no such thing as a truly rot-resistant wood, so preservatives especially green copper have been used for years to protect it. Beyond the availability of wood rot fixers. Today, we have access to types of wood preservative which can be painted or sprayed directly onto a timber structure after construction. However, depending on the building design and its positioning, it’s often better to buy wood that has been treated before being used for assembly or putting into the ground as poles or posts.
New Wood Treatments
To fight against fungus and insects wood merchants turned to copper-based preservatives. For many years, they used a compound called CCA. Copper was the main agent used in this mixture to kill the fungus, with arsenic added as an insecticide and a secondary fungicide. Chromium was incorporated to ‘fix’ the compound to the wood tissue and stop all three leaching into the soil over time. Copper gave the treated wood a green color, leading to it being called
green copper treatment.
With the discovery that, despite the ‘fixing’, arsenic did eventually find its way into the soil, changes had to be made to the composition of green copper treatments.
The Wolmanized brand now primarily uses a different copper compound called Copper Azole, which contains a non-arsenic insecticide. This is deemed safe and is in common use throughout the U.S. for garden and home applications. The wood still has the same green coloration and can be used with any kind of wood finishes.
Some Wolmanized wood is still treated with CCA, particularly for poles in fields and timber that might be subjected to extreme damp or attack from termites.
Tips on Pressure treated wood
To ensure the greatest efficiency from the preservative, wood is pressure treated. During the process, the timber is sealed in a tank and all the air is extracted to create a vacuum. The green copper solution is pumped into the tank and because of the vacuum, it’s absorbed deep into the wood. The oxides in the solution react with the wood fibers to ‘fix’ the preservative and prevent it seeping into the soil.
Can you stain or paint Treated Wood
Staining treated wood may not be possible for a few months to allow the wood to dry completely. To check if it is ready, sprinkle a few drops of water onto the surface. If the water is absorbed into the wood, you can either stain or paint the wood immediately.
Staining pressure treated wood can normally be done within a few days of completing the building work of your molding and millwork because it is often dried before sale.
