Get the Best Results for Outdoor Treated Timber Projects

Koppers treated timber products are durable and versatile building materials. The following tips will help you get the best results with your treated wood project.

• Make sure that the timber is treated to the correct hazard level for your application. The most common situations are:
  H3 for above ground such as decking and pergolas
  H4 for ground contact such as landscaping and fence posts
  H5 for structural application in ground contact such as house poles, engineered retaining walls, or for timber that will be in permanent fresh water contact.
  
• All end cuts, rebates, drill holes and notches should be resealed with an approved "in can" timber protective such as Tanalised^® Enseal Clear and Tanalised^® Ecoseal.
• It is strongly recommence that all dimensioned (sawn) timber products in outdoors situations are painted, stained or sealed for best performance and prevention of discolouration, mould and dimensional distortion.
• Use hot dipped galvanised steel, stainless steel or other metal fasteners of high corrosion resistance for all exterior timber applications.

You will never regret the small additional cost of taking these steps when you appreciate the long term benefits of durable outdoor structures using Koppers Tanalised^® treated timber.
