WHATS THE DIFFERENCE BETWEEN GREEN AND BROWN TREATED WOOD?
If you are shopping for treated lumber at a do-it-yourself retail centre, you may be confused by the choices and store staffers may not know much more than you do. Whether the treated wood on display is green, brown, or bears a brand name, it’s all been treated with a copper-based preservative. The brown products have merely been coloured to mask the greenish tone of the preservative. This colouring is not permanent and may fade away, leaving you with wood that looks the same as the green version at the store. Note that the green tone of treated wood will fade as the wood ages, without any effect on the wood protection.
