Treated Lumber FAQ

Treated lumber is not like other types of wood. In fact, treated lumber has a number of different traits that need to be addressed when using it. Have a question about the Yellawood® treated lumber you are using for your project? Check out these frequent inquiries below:

What preservatives are used with pressure treated lumber?
Each type of treated lumber has its own unique blend of preservatives used to help create its strength and beauty. Some popular lines – like Yellawood® treated lumber – use a micronized copper preservative and a co-biocide.

What does “ground contact” mean?
When a treated lumber boasts “ground contact” attributes, that means it is made with being placed in or on the ground in mind. This is important for projects such as fences, deck posts, flower beds, etc., and means that the lumber will resist the harsh elements. “Ground contact” accessible treated lumber can also be great for above ground projects, as they will be able to withstand extreme situations – like Kansas City weather.

Is it a bad piece of treated lumber if I cut it open and the middle looks untreated?
The middle section of treated lumber is typically naturally resistant to decay, rot, mold, and other elements that could harm the integrity of the wood. Treated lumber that has this appearance in the middle is still good to use.

What fasteners should I use with treated lumber?
Fasteners that resist corrosion and will not stain your treated wood are best. Consider galvanized or stainless steel fasteners for your treated lumber projects for this reason.

Can Yellawood® treated lumber be used in gardens?
Yes, through scientific studies it has been found that the chemicals used in treating this lumber is biologically inactive, and thus safe for use in gardens.

When should I paint or stain my project?
When small amounts of water are placed on your treated lumber and it is absorbed readily, you can proceed with painting or staining. Oil-based primer and latex paint are best, while an oil-based stain will also give a great shade to your project.
