Timber preservation

Since timber is a natural product, there are natural elements which, during natural cycles use it as food and shelter (including humans).

There are effective ways to protect your investment, and give it more value, all this is covered in detail in the class.

Some timber needs protection from wood boring beetles and rot. This depends on the circumstances, where and how the timber is used, species, location, climate, etc.

Some timber does not require any treatment against beetles, this is discussed in class.

Personally, I do not believe in exposing myself or my family to any potentially harmful chemicals if not absolutely necessary.


Common treatments include:

CCA preservative treated timber

  1. As of January 1, 2004, EPA will not allow CCA products to be used to treat wood intended for most residential settings.
  2. Do not compost or mulch sawdust or remnants from CCA-treated wood.
  3. Do not burn CCA-treated wood, as toxic chemicals may be released as part of the smoke
  4. After working with the wood, wash all exposed areas of your body, especially the hands, thoroughly with soap and water before eating, drinking, toileting, or using tobacco products.
  5. Wash your work clothes separately from other household clothing before wearing them again.
