Anti-sapstain

Wood is an attractive and decorative material which is potentially at risk from wood-staining fungi from the time it is cut at the saw mill until it is treated. This can result in blue or black stains on the wood's surface, leading to a loss in value and rendering it unsuitable for high-quality, decorative uses on buildings, in gardens and furniture.

You can find more information on wood-staining fungi in our Infocenter wood.

Treatment Processes

Freshly cut wood, such as side lumber and boules, is usually treated in by dipping or in a spray tunnel.
In these processes, the preservatives penetrate the wood by means of capillary forces and diffusion or through the hydrostatic pressure of the liquid preservative in the dipping tank.
