The non-painted side of your board will warp if you paint it before it’s dry. You get warping when one side dries faster than the other. If you wait until the wood is dry, you will end up with warped wood, peeling paint, and a warped board.
If you don’t paint your wood before you apply it to your board, it won’t warp. But if you wait too long, the paint will dry on the painted side first, then the untreated side. That’s why you need to paint the treated side before applying the board to it.

Can I paint a newly treated wood?
Yes, you can paint or stain pressure-treated wood, but for a long-lasting and great-looking finish evaluate the wood’s moisture content first, then use the stain or paint. Pressure treated wood has been treated to make it more resistant to moisture. This means that it is more likely to absorb moisture from the air than untreated wood.
How can you tell if pressure treated wood is dry?
The “sprinkle” test can be used to determine if pressure treated wood is dry enough to stain. Sprinkle water on the wood: if the wood absorbs it within 10 minutes, plan to stain as soon as possible. The wood needs more time to dry if the water beads or pools on the surface.
If you’re not sure whether a wood stain will work on a particular piece of wood, you can test it by soaking it in water for a few minutes before applying the stain. You can also use a test strip to see how much stain you need to apply.
Why can’t you paint pressure treated wood right away?
Because it is not thoroughly dry, new pressure treated lumber can quickly warp and bend if you don’t handle it correctly.
Wait at least 60 days to allow the wood to dry completely after building with new pressure treated lumber, or keep it stacked flat in a dry place and build with it right away.
If you are building a new home or remodeling an existing home, be sure to check with your local building department to make sure the lumber you purchase is properly treated.
How long does it take for treated wood to dry?
The fastest way to dry treated wood is by kiln drying it. It will take one to eight weeks. If you want to speed up the drying process, you can lay the treated wood flat and stack them in a pattern.
If you don’t want to use kilns, you can dry your wood by using a dryer. Dryers can be found at most home improvement stores. If you have a wood burning stove, use it to heat the wood to a temperature that will dry it quickly.
Does pressure treated wood need to be primed before painting?
Only once you’ve confirmed that it’s dry can you begin painting pressure-treated wood. Make sure that the manufacturer lists the coating as suitable for use on wood surfaces, if you start with primer formulated for exteriors. If you’re painting a wood surface that’s already been treated with a primer, you’ll need to apply a second coat of primer.
Is it better to paint or stain pressure treated wood?
You can stain pressure treated wood instead of painting it. The process used for curing the wood is the reason why paint rarely sticks to pressure-treated wood. Wood stain comes in a wide variety of colors and finishes, and it can be applied to almost any type of wood surface. It’s also a great way to add a touch of class to any room you decorate.
Can I paint treated lumber right away?
Pressure treated wood needs time to dry out before it’s primed or painted. You can expect it to take 3-4 months for the levels to go down. When it absorbs water instead of soaking it up, the treated wood is ready to paint.
If you’re painting a wood that’s already primed, you’ll want to wait until the wood dries out completely before painting it. This will allow the paint to fully dry before you paint it, and it will also allow you to remove any excess paint that may have built up during the curing process.
How do you know if wood is dry enough to paint?
The bead test is also a good way of determining if the wood is too wet to paint. Sprinkle some water on the wood. If it beads up, it means the fibers in the wood are resisting the water because they are already saturated with moisture. If this is the case, the wood won’t be able to absorb the paint, and you’ll need to add more water.
If the beads don’t bead up when you spray paint on it, you’re good to go. But if they do, spray a little more paint onto it and let it sit for a few minutes to let the moisture evaporate. Repeat this process until you’ve painted the entire piece.
