Staining Pressure-treated wood gives it an extra dash of protective covering, prolonging its longevity and giving it a glamorous allure.
Thus, how can you determine if pressure-treated wood is ready for staining?
To help answer this question, we shall consider a couple of scenarios.
However, pressure treatment and staining can amount to some damaging results if not undertaken correctly.
To ascertain whether a pressure-treated wood has achieved the right moisture content for it to undergo staining.
You first have to conduct the ‘sprinkle test.’ Wondering how to go about it, the test involves sprinkling water on the wood piece to be stained.
If it absorbs the water within the first ten minutes, it’s ready for staining.
However, if you encounter that, the water stagnates or forms some beads on the piece of timber’s surface.
It thus means that the wood hasn’t entirely dried thoroughly.
Another way to check is that if you lift the timber piece and it feels heavy in your hands, it needs to dry further.

For the best staining results and ease of working with the wood, you should ensure that you stain a completely dry wood or risk redoing the work.
The Best Time for Staining Pressure Treated Wood
The best time to stain pressure-treated wood depends on several factors, including the weather, the age of the wood, and the type of stain you’re using. Here are some general guidelines to help you determine the best time to stain pressure-treated wood:
i. Age of the wood
Newly installed pressure-treated wood needs time to dry out and acclimate to the environment before it can be stained. The time it takes for the wood to dry out depends on several factors, including the climate and the type of wood. Generally, it’s best to wait at least four to six weeks after the wood has been installed before staining it. This will give the wood enough time to dry out and reach a moisture content of 15% or less.
ii. Weather conditions
The weather plays a crucial role in the staining process. Choosing a day with mild temperatures (between 50°F and 90°F) and low humidity (less than 50%) for staining pressure-treated wood is important. High humidity can cause the stain to take longer to dry, while extreme heat or cold can affect the application and adhesion of the stain.
iii. Type of stain
The type of stain you’re using also plays a role in the best time to stain pressure-treated wood. Oil-based stains take longer to dry and cure, so it’s best to avoid staining during periods of high humidity, extreme heat, or cold. Water-based stains dry faster and are less affected by weather conditions, but they may not penetrate the wood as deeply as oil-based stains.
The best time to stain pressure-treated wood is during the spring or fall when temperatures are mild and humidity is low. Staining during the summer or winter can be challenging due to extreme weather conditions and high humidity.
Additionally, the best time to stain pressure-treated wood is during mild weather conditions when the wood has had enough time to dry out and acclimate to the environment.
It’s important to choose the right type of stain and follow the manufacturer’s instructions for proper application and drying times.
Considering these factors, you can ensure that your pressure-treated wood will be properly protected and look great for years to come.
There are different varieties of wood treatment processes available locally.
- Wet pressure-treated wood– The process involves impregnating the preservatives into the wood using force.
It usually appears greenish colour when you collect the timber from the hardware. The drying period is around 2-3 weeks in low-humid areas.
- Kiln-dried pressure-treated wood– the process involved in infusing the preservative is more like a wet process, but the variation comes during the drying stage.
The kiln-dried lumber comes fitted with a stamp or tag indicating ADAT, i.e., Air-dried after treatment or KDAT, i.e., Kiln dried after treatment.
The stamp shows the process the wood has undergone and that it can stain without further treatment.
The kiln process is more effective in that it helps in preventing the warping of the timber, a phenomenon witnessed during drying.

Staining pressure-treated wood is a great way to protect it from the elements while enhancing its appearance. Pressure-treated wood has been treated with chemicals to increase its resistance to decay, rot, and insects.
This makes it popular for outdoor projects such as decks, fences, and pergolas. However, pressure-treated wood can be difficult to stain due to its high moisture content and the chemicals used to treat it.
Note There are a couple of considerations to put in place, for example, when staining over factory-processed timber.
The moisture content might be right, but the wood isn’t ready to be stained yet. You must sand over the wood or use a neutralizer to remove the glazed mill layer. The layer usually results from the heat and pressure used during manufacturing. Test for a mill glaze layer by sprinkling water.
If the water beads on the surface, it’s evidence of a glazed layer.
In this blog, we will review the steps and materials needed to stain pressure-treated wood successfully.
Step 1: Prepare the wood
Before staining pressure-treated wood, it is important to let it dry completely. Pressure-treated wood typically comes with a high moisture content, making it difficult for the stain to adhere properly. Letting the wood dry for several weeks or even months is ideal, but if you’re pressed for time, you can use a moisture meter to test the wood’s moisture content. Once the wood has dried to a moisture content of 15% or less, it is ready to be stained.
Step 2: Clean the wood
Before staining the wood, cleaning it thoroughly to remove any dirt, debris, or grime is important. You can use a pressure washer, a stiff-bristled brush, and a cleaning solution to clean the wood. Be sure to let the wood dry completely before proceeding to the next step.
Additionally, test for the moisture content in the wood. Once you have ascertained that the wood has dried, you can rule out any wrong assumptions by conducting the following test.
You can conduct a bead test to ascertain the moisture content, as we had outlined earlier. Alternatively, you can hammer a nail directly into the wood and check for any water that will seep out.
If you notice some wetness when driving in the nail or beading water, you must let it sit on for a more extended period to be completely dry.
Step 3: Choose the right stain
When choosing a stain for pressure-treated wood, it is important to choose a product that is specifically designed for this type of wood. Look for a stain that contains a water repellent and a UV inhibitor to protect the wood from moisture and sun damage. There are two types of stains to choose from: oil-based and water-based. Oil-based stains tend to penetrate the wood deeper and last longer, while water-based stains are easier to clean up and dry faster.
Step 4: Apply the stain
Before applying the stain, it is important to stir it thoroughly to ensure the colour is consistent throughout. You can apply the stain using a brush, roller, or sprayer. Be sure to apply the stain evenly and work in small sections to avoid overlap marks. If you’re using a sprayer, be sure to follow the manufacturer’s instructions for proper use and cleaning.
Step 5: Allow the stain to dry
After applying the stain, letting it dry completely before using the wood is important. The drying time will depend on the type of stain you used and the weather conditions. Oil-based stains typically take longer to dry, while water-based stains dry faster. Be sure to check the manufacturer’s instructions for specific drying times.
Step 6: Apply a second coat (optional)
If you want a deeper colour or added protection, you can apply a second coat of stain once the first coat has dried completely. Be sure to follow the same application process as before, and allow the second coat to dry completely before using the wood.

Is it OK to stain pressure-treated wood?
Yes, it is generally okay to stain pressure-treated wood. Pressure-treated wood is treated with chemicals to resist decay, rot, and insects and can last many years. However, pressure-treated wood can be difficult to stain due to its high moisture content and the chemicals used to treat it. If you’re planning to stain pressure-treated wood, there are a few things to keep in mind:
- Wait for the wood to dry: Newly installed pressure-treated wood needs time to dry out and acclimate to the environment before it can be stained. It’s best to wait at least four to six weeks after the wood has been installed before staining it. This will give the wood enough time to dry out and reach a moisture content of 15% or less.
- Choose the right stain: When choosing a stain for pressure-treated wood, choosing a product specifically designed for this type of wood is important. Look for a stain that contains a water repellent and a UV inhibitor to protect the wood from moisture and sun damage. There are two types of stains to choose from: oil-based and water-based. Oil-based stains penetrate the wood deeper and last longer, while water-based stains are easier to clean up and dry faster.
- Apply the stain properly: Before applying the stain, it’s important to clean the wood thoroughly to remove any dirt, debris, or grime. Apply the stain evenly and work in small sections to avoid overlap marks. If you’re using a sprayer, follow the manufacturer’s instructions for proper use and cleaning. Letting the stain dry completely before using the wood is also important.
- Sand the wood: Sanding the wood before applying the stain can help to open up the wood’s pores and create a smoother surface for the stain to adhere to. Use fine-grit sandpaper to lightly sand the surface of the wood, being careful not to over-sand and damage the wood.
- Test the stain: Before applying it to the entire surface, it’s a good idea first to test it on a small, inconspicuous area. This will give you an idea of how the colour will look and whether the wood will absorb the stain evenly.
- Use a brush or roller: While a sprayer can be an efficient way to apply stain, using a brush or roller can help you to apply the stain more evenly and control the amount of stain applied. Be sure to use a brush or roller specifically designed for stain use.
- Apply multiple coats: Depending on the type of stain you’re using and the desired colour intensity, you may need to apply multiple coats. Be sure to let each coat dry completely before applying the next coat.
- Seal the wood: After the stain has dried completely, applying a sealer to the wood is a good idea to provide an extra layer of protection. A clear sealant will help to protect the wood from moisture and UV damage and can also help to enhance the colour of the stain.
Is it better to paint or stain pressure-treated wood?
Whether to paint or stain pressure-treated wood depends on your preference, the look you want, and the level of protection you want for your wood.
Painting pressure-treated wood can provide a smooth, even finish and comes in various colours. Paint also provides a thick layer of protection against the elements, including UV rays, moisture, and mildew.
However, painted surfaces may be more prone to peeling, cracking, or chipping over time, especially in high-traffic areas.
Staining pressure-treated wood, on the other hand, allows the natural beauty of the wood to shine through while still protecting the elements. Stain penetrates the wood more deeply than paint, which can help to prevent cracking and peeling over time.
Stain also comes in various colours and finishes, including clear, semi-transparent, and solid, allowing you to achieve the desired look for your project.
In general, if you want to enhance the natural beauty of the wood and maintain a more natural look, staining is a good option.
Painting may be better if you want a more uniform and colourful finish or if you need maximum protection against the elements.
Ultimately, the decision between paint and stain will depend on your personal preference and the specific needs of your project.
What kind of stain do you use on pressure-treated wood?
When selecting a stain for pressure-treated wood, choosing a product specifically designed for this type of wood is important. Look for a stain that contains a water repellent and a UV inhibitor to protect the wood from moisture and sun damage.
There are two main types of stain to choose from: oil-based and water-based.
Oil-based stains are known for their durability and longevity, as they penetrate the wood deeply and provide excellent protection against moisture and UV damage. They are also known for their rich colour and attractive finish. However, oil-based stains can be more difficult to clean up and may emit strong fumes during application.
Water-based stains, on the other hand, are easier to clean up and dry more quickly than oil-based stains. They are also more environmentally friendly and emit fewer fumes during application. However, they may not provide as much protection against moisture and UV damage as oil-based stains and require more frequent reapplication.
Ultimately, the choice between oil-based and water-based stain will depend on your personal preferences and the specific needs of your project. Be sure to read the product label carefully and choose a stain designed specifically for pressure-treated wood use.
What happens if you don’t stain pressure-treated wood
If you don’t stain pressure-treated wood, it will still be resistant to decay, rot, and insect damage due to the chemicals used to treat it.
However, over time, untreated pressure-treated wood can become discoloured, rough, and unattractive due to exposure to the elements.
UV rays from the sun can cause the wood to grey and fade, while moisture can cause the wood to swell, warp, and split. In addition, without a protective layer of stain, the wood can become more susceptible to mould and mildew growth.
While pressure-treated wood does not need to be stained to be protected from decay, staining the wood can help to enhance its appearance, protect it from the elements, and prolong its lifespan.
By applying a high-quality stain and sealer to your pressure-treated wood, you can help to maintain its natural beauty and protect it from moisture, UV rays, and other damaging factors.
