Waiting for the wood to dry allows for better absorption and adhesion of the stain or paint, resulting in a more durable and attractive finish.

Reasons Why Wood Needs To Dry

Pressure treated wood is infused with preservatives to protect it from decay and termite damage. However, the wood needs to dry out before it can be used in construction. There are two main reasons for this:

  • Moisture content: Pressure treated wood is wet when it comes out of the treatment process, with a moisture content of around 50%. This high moisture content can cause problems when the wood is used in construction, such as warping, splitting, and shrinking.
  • Adhesion: If you try to paint or stain pressure treated wood before it has dried out, the paint or stain may not adhere properly, resulting in a poor finish.

Kiln Dried Vs. Air Dried Wood

There are two main ways to dry pressure treated wood: kiln drying and air drying. Kiln drying involves placing the wood in a large oven and heating it to a temperature of around 140 to 170 degrees Fahrenheit. This process typically takes between 24 and 48 hours and results in wood that is dry and ready to use.

Air drying, on the other hand, involves stacking the wood in a dry, well-ventilated area and allowing it to dry naturally. This process can take several months, depending on the climate and humidity levels in your area.

How To Test If Pressure Treated Wood Is Dry

There are several ways to test if pressure treated wood is dry enough to use:

  • Water Sprinkle Test: Sprinkle a few drops of water onto the surface of the wood. If the water beads up, the wood is still too wet. If the water is absorbed into the wood, it is ready to use.
  • Moisture Meter Test: Use a moisture meter to test the moisture content of the wood. A moisture content of around 15% is ideal for most construction projects.

In conclusion, it is important to let pressure treated wood dry out before using it in construction. Kiln drying is the fastest and most reliable way to dry the wood, but air drying can also be effective if you have the time and space. By understanding the drying process and testing the moisture content of the wood, you can ensure that your construction project is a success.

Pressure treated wood comes in various levels of treatment, such as Above Ground Contact and Ground Contact. The level of treatment can significantly impact the drying time of the wood. Wood treated for ground contact tends to retain more moisture and may require a longer drying period compared to wood treated for above ground use. The higher the treatment level, the more time it may take for the wood to dry completely.

Testing For Dryness

To determine how long it takes for pressure treated wood to dry, you can use various methods such as testing moisture with a moisture meter or sprinkling water on the surface to see if it beads up or absorbs. It’s recommended to let the wood dry before installing to avoid inconsistent gapping and stress on the fasteners.

However, it could take up to 60 days for the wood to fully dry.

Pressure treated wood is a popular choice for outdoor projects because it is resistant to decay and insects. However, it is important to let the wood dry out before staining or painting. But how do you know when the wood is dry enough? In this section, we will discuss two methods for testing the dryness of pressure treated wood.

Water Sprinkle Test

One simple way to test the dryness of pressure treated wood is to sprinkle a few drops of water onto the surface of the wood. If the water beads up and sits on top of the wood, it is not yet dry enough. But if the water is absorbed into the wood, it is ready for staining or painting.

Using a Moisture Meter

Another method for testing the dryness of pressure treated wood is to use a moisture meter. This tool measures the moisture content of the wood and can give you a more accurate reading than the water sprinkle test. To use a moisture meter, simply press the prongs of the device into the wood and read the moisture level on the display. A moisture level of 15% or lower indicates that the wood is dry enough for staining or painting.

It is important to note that the drying time for pressure treated wood can vary depending on the climate and the conditions in which the wood is stored. In general, it can take anywhere from a few weeks to a few months for pressure treated wood to dry out completely.
