CCA Fact Sheet

Click to view large

A Resource worth Preserving

Generally, the label authorizes use of CCA in most industrial and commercial applications. Most of those applications are heavy retention treatments of 0.50 or more pounds per cubic foot.

Examples of CCA Uses that will be permissible under the new label language

The following list is taken from the 2001 edition of the AWPA standards to illustrate examples of the types of wood that fall within each standard. While the list is not exhaustive, it does provide some examples of specific uses within each AWPA commodity standards that may be treated with CCA.

Painting and Staining or Natural Weathering

• CCA can be painted or stained to match any outdoor color scheme.
• High quality oil and latex-based paints and stains are recommended.
• Water repellent coatings can be applied to improve weathering performance.
• Left uncoated or with clear water repellent coatings, CCA will weather to a natural gray color.
• It is important to ensure that the wood is dry and free from surface deposits prior to applying any coating.

Nails, Fasteners and Fittings

Hot dipped galvanized or stainless steel fasteners and fittings are recommended. Anti-corrosion coatings applied to fasteners and fittings in contact with treated wood will enhance long-term performance. Direct contact of CCA treated wood with aluminum fasteners and fittings is not recommended.

CCA Recommended Retentions for Various Non-Residential, Industrial and Commercial Applications

Application - Retention (lbs/CuFt) - Uses:

• Above Ground - 0.25
• Ground Contact, - 0.40
