  • Stainless Steel

Plywood Treatments and Standards

AWPA Standard C9, "Plywood - Preservative Treatment by Pressure Process," specifies that the preservative-treated panel be redried to a moisture content of 18% or less, unless waived by the specifier.

Treated plywood is often used in construction applications and is not necessarily re-dried after treatment. It is essential for boat manufacturers to specify redrying.

Treated plywood is trademarked by a grading agency that monitors treating quality. The trademark should specify the AWPA standard, treatment and treating retention.

Handling and Use Recommendations
Use Site Precautions

Wood pressure treated with waterborne arsenical preservatives may be used inside residences as long as all sawdust and construction debris are cleaned up and disposed of after construction.

Do not use treated wood under circumstances where the preservatives may become a component of food or animal feed. Examples of such sites would be structures or containers for storing silage or food.

Do not use treated wood for cutting-boards or countertops.

Only treated wood that is visibly clean and free of surface residue should be used for patios, decks, and walkways.

Do not use treated wood for construction of those portions of beehives, which may come in contact with the honey. Treated wood should not be used where it may come in direct or indirect contact with public drinking water, except for uses involving incidental contact such as docks and bridges.
