Any nails in the new treated material should be galvanized.
Treated lumber is primarily treated to resist decay, insects, and fungal growth, which extends its lifespan when used in outdoor environments or areas prone to moisture. The treatment process typically involves the infusion of preservatives, such as copper-based compounds, that protect the wood from rot and pests. This makes treated lumber ideal for applications like decks, fences, and landscaping. It’s important to note that treated lumber may require special handling and precautions during installation and disposal due to the chemicals used.
Yes, you can paint treated lumber immediately after installation.
To determine if lumber is treated, you can look for a stamp or label on the wood indicating that it has been treated with preservatives. Additionally, treated lumber may have a greenish tint or a chemical odor. You can also ask the supplier or check the product specifications for information on whether the lumber has been treated.
Treated lumber should be used in outdoor construction. There are different types of treated lumber, some are for above ground use and some are for below grade use.
You can typically begin painting treated lumber after it has dried completely, which usually takes about 24 to 48 hours.

You might be referring to 'pressure treated' lumber, or lumber that has been milled but not dry.
Older pressure treated lumber known as CCA was treated with 3 substances, Chrome, Copper, and Arsenic. Newer treated lumber intended for consumer contact is now treated with different chemicals, such as copper/boron. Lumber NOT intended for consumer contact, such as buried or submerged lumber may still be CCA treated. PS- it is not a good idea to burn ANY treated lumber. If it kills bugs and fungi, it is likely not real good for you, either.
The best deck screws for treated lumber are stainless steel screws or coated deck screws specifically designed for use with treated lumber. These screws are resistant to corrosion and will provide a secure hold in the treated wood.
Yes, you can stain treated lumber, but it is important to wait for the wood to dry completely before applying the stain.
Yes, pressure treated lumber may shrink over time as it dries out.
Treated lumber can last several years in water, typically ranging from 5 to 20 years, depending on the type of treatment used and environmental conditions. The preservatives used in treated lumber help resist decay and insect damage, but continuous exposure to water can accelerate wear. It's important to choose the right grade and type of treated lumber for specific applications, as some treatments are better suited for aquatic environments than others. Regular inspections can help determine when replacement is necessary.
