Why treat?

The risks

Wood needs protection whether fence & gate posts or building timbers, panels, pergolas, playground apparatus -. Particularly when used outdoors in constant contact with earth or water, our indigenous, relatively low durability wood types are at risk from fungi, insects and the elements. Vacuum pressure impregnation can provide lasting protection for these types of timbers..

Care of treated wood

The cross cut ends of impregnated timbers should be treated with Wolmanit® Cut & treat.
