Frequently Asked Questions
What does ground contact rated mean?
The treatment retention meets AWPA Use Category UC4A, so the piece is approved for direct soil or standing water contact, on-grade framing, and other hard service locations, as well as everything above grade.
Which fasteners should I use?
Hot-dip galvanized or stainless steel fasteners and connectors rated for treated lumber. Standard bright fasteners corrode in contact with the preservative.
Can I paint or stain it right away?
No. Treated stock ships wet. Allow it to season until water no longer beads on the surface, typically several weeks exposed, before applying finish.
What is the actual size of a treated 4x6?
3.5 in. x 5.5 in. at time of manufacture. Treated lumber can vary slightly with moisture content as it seasons.
