Method of impregnating wood |
| abstract |
Method of impregnating wood in order to protect it against fungal decay. Conventionally wood has been treated with copper-chromium-arsenic preservatives in a one stage treatment, e.g. by impregnating the wood with a solution of these compounds. The chromium component serves to fix the copper in the wood to prevent it from leaching out. It has now been found that a two-stage treatment in which (1) the copper and fixative agent are impregnated without arsenic and (2) the arsenic is impregnated separately, improves resistance of the wood to soft-rot fungi. The invention is particularly useful for treating hardwoods. |
