Pre-Treatment Difficult-to-treat species must be incised in a pattern of sufficient coverage and density to obtain uniform penetration of the borates.
Preservation Process Tim-bor® Industrial Wood Preservative is applied as an aqueous solution using vacuum/pressure treating process that forces the preservative into the sapwood.
|
Following pressure treating, the wood product is covered and moved to a controlled environment to allow the borates to diffuse further into the wood.
Post-Treatment Plywood should be kiln-dried following pressure treatment. The moisture content should approximate that which the product will attain in use (approximately 18 percent for general building applications). For lumber, re-drying after treatment is recommended. Most building codes require the moisture content of lumber to be 19% or less at the time of installation. |
