10 Ways About How to Keep Pressure Treated Wood From Warping

1. Store the Wood in a Dry Area

Make sure the area where the wood is stored is not prone to moisture, as this can cause warping. So make sure to store it in a dry area such as a garage or shed.

2. Choose the Right Wood

Depending on the project, choose a type of pressure-treated wood that is less prone to warping such as cedar or redwood. You have to consider the level of exposure to moisture and the weight that the wood will endure during use.

3. Use Protection

Apply sealants or coatings to your pressure-treated wood to protect it from harsh weather conditions and UV rays. This will also prevent warping caused by moisture buildup. Additionally, avoid placing pressure-treated wood in direct contact with soil or water, as this can cause additional warping and damage.

4. Proper Storage

Store pressure-treated wood on a flat, dry surface, and use spacers to allow air circulation. This will prevent warping caused by uneven pressure or moisture buildup. So make sure not to stack the wood too high and maintain proper storage to prevent warping.

5. Regular Maintenance

Inspect your pressure-treated wood regularly for signs of warping, and take measures to fix any issues as soon as they arise. This can include applying sealants or coatings, adjusting storage methods, or making structural repairs.

6. Seal or Stain Right Away

Seal or stain the wood immediately after installation to prevent warping caused by water damage. Re-seal or re-stain every 1-2 years as necessary to continue protecting against moisture damage. So if you want to keep your pressure-treated wood from warping, remember to use protection, store properly, maintain regularly, and seal or stain right away.
