To know how to dry pressure treated wood, you must first make sure that you have researched this wood.
Pressure-treated wood has undergone special treatment to resist rot, insect infestation, mold, and water damage. Some pressure treatments can even make wood fire resistant.
It comes in many varieties, each of which serves a variety of purposes. Swing sets, decks, picnic tables, fences, and other outdoor structures benefit from the use of this outdoor wood.

How To Dry Pressure-Treated Wood?
There are a few techniques you can do if you desire to dry your wood without any warping, but the two most straightforward and quickest ways to do it are:
- Use the oven to dry the wood
- Let the wood dry naturally in the air
Let’s discover how to speed up drying of pressure-treated wood.
Using Conventional Oven Drying
Drying pressure-treated wood in a standard oven is one of the simplest methods available to you. For small volumes of wood, you should use this method.
It is better not to leave the oven unattended or without a fire extinguisher in the event of a fire, as operation can be hazardous.
Step 1. Prepare The Oven
Rearrange your oven’s shelves with one at the bottom and the other in the center. Using a center rack will ensure that each side of the pressure-treated wood dries equally.
To catch any small pieces that get through, place a large saucepan on the bottom rack.
Most ovens have a built-in thermometer, but if you want to avoid getting too dry, place a second oven-safe thermometer on the middle rack.
Step 2. Temperature Setting
If you have a conventional oven, pre-set the temperature between 200 and 225 degrees Fahrenheit as the most appropriate level and start the convection fan.
If the temperature is too high, the wood will warp or break.
Step 3. Check Wood Moisture
Before putting the pressure-treated wood in the oven, check the moisture content of the wood. This step is to determine the ideal time of drying.
An electronic moisture meter is the best technique to determine the moisture content in a piece of wood.
If you don’t have that tool on hand, you can estimate the moisture through the wood weight. The heavier than usual, the wetter it is. Of course, this way is just a final resort and can’t bring out an accurate result.
Step 4. Put In The Oven
On the center shelf, arrange your pressure-treated wood pieces. Spread your pieces of wood neatly to keep the distance.
If any of your pieces of wood come into contact with each other, they may not dry completely.
Before closing the oven, double-check the temperature and position of the pressure-treated wood again.
Step 5. Wood Drying
Close the oven door after setting the timer for one hour. Keep an eye on the oven and prepare a fire extinguisher while the pressure-treated wood dries.
Pay close attention to the baking wood because there is always a risk of catching fire when heating the wood.
Step 6. Check Moisture After Drying
After one hour of baking, verify the moisture content of the pressure-treated material using a moisture meter or reweigh the wood.
Carefully transfer the wood from the oven to the rack using a large set of tongs or thick gloves to prevent burns.
If your pressure-treated wood needs further drying (still wet and heavier than usual), continue to heat the wood in the above steps for another fifteen minutes.
Step 7. Cooling
Lift each piece of pressure-treated wood out of the oven and place it on a wire cooling rack using a pair of large tongs or thick gloves. Spread the details out to cool evenly and avoid contact with hot wood.
Step 8. Check The Surface
Once cool, look for cracks or dry spots. Wood can crack or deform due to heat. Inspect each piece of timber to ensure a fine finish.
You can use pressure-treated wood glue or epoxy to seal a small enough fracture.
Wrapping the wood with a damp cloth and ironing will help prevent it from warping. Straightening pressure-treated wood in this way can be pretty laborious.
Using Air Drying
Air-dried pressure-treated lumber is a simple and highly successful process that won’t let you down when following the correct procedure.
If you’re patient enough to wait for the wood to dry and have enough space, follow the instructions below to understand how to apply this method:
Step 1. Find A Suitable Place
Find a flat site, out of the sun, not in an area prone to flooding.
Avoid drying pressure-treated wood in place with too much sun because it can cause the wood to warp and crack for uncontrolled solar heat levels.
The area should be large enough for the length of the boards to be completely dried.
Step 2. Place Padding Board
Arrange three pieces of wood about 4 x 4 inches x 4 feet on a flat, evenly spaced area.
The pieces must be parallel to each other and appropriately spaced to accommodate the wood placed on top of these components.
On top of the 4×4, order the pressure-treated wood first, leaving 1/2 inch between each sheet.
Then put three more thin strips of wood in the same areas as the 4×4 on the ground.
Step 3. Put The Pressure-Treated Wood On
In the same way as the first row, place the pressure-treated wood on top of these strips. Scatter these lumber slats again until all wood turns into a pile.
Air can move freely through the laminate because the stacking process has a backing layer that circulates air between the pressure-treated layers and dries the wood efficiently.
Step 4. Put The Protective Coating On
Cover the woodpile with a tarp. You should leave space at each end for the wind to get through and dry your wood.
Place bricks with appropriate distance on top of the canvas. It will secure the canvas from being blown away by the wind.
Step 5. Wait For The Wood To Dry
Leave the wood dry for about two or three weeks before testing for proper moisture using a wood moisture meter or wood weighing method.
There is no fixed answer to the question: “How long does it take pressure-treated wood to dry precisely ?” because it depends on many factors and the dryness you desire.
If you feel the wood hasn’t reached the desired dryness, you can leave the wood in that condition for a few more days to allow it to dry completely.

Frequently Asked Questions
How Long Does It Take For Pressure-Treated Wood To Dry?
Knowing how long for pressure-treated pressure wood to dry is essential in the use of wood.
It usually takes about three days to dry, depending on the weather and the type of wood.
On the other hand, conventional pressure-treated wood purchased from the home center takes two to three days to cure before applying a water-based semi-transparent stain fully.
You can sprinkle some clean water on the wood surface to see if it is dry enough as you want.
Is It Necessary To Wait For Pressure-Treated Wood To Dry Before Using?
The first piece of advice is to let the pressure-treated wood dry before use. For example, redwood and cedar are both dry when purchased.
However, treated lumber has many chemicals and water pumped inside, so it’s often wet or damp when you buy it.
After reading our article, we hope you will know how to dry pressure-treated wood in practical ways. If the wood is small enough, you can dry them using an oven. Otherwise, opt for air drying, but it’ll certainly take a longer time.
