Choosing the best pressure-treated wood involves considering warranties, moisture levels, and intended use. Low moisture wood is recommended to prevent warping and rot. Check warranties for coverage and duration, and consider coatings for specific needs. Consider environmental impact and choose wood suitable for above or below ground use.
Pressure-treated wood is wood that has been treated with chemicals to help it resist weather and insect damage, and there are many things to consider when trying to choose the best. Most sellers of pressure-treated wood offer warranties on the wood, and looking for the best warranty can be a good place to start. Moisture can be a problem with this wood, thanks to the chemical treatment, and getting a low moisture wood is generally a good idea. This wood is divided into categories above ground and in contact with the ground, and you should choose wood based on how you will be using it. Some woods also have extra finishing materials that can be helpful.
Many woods offer warranties, but pressure treated wood tends to have longer warranties than most other woods. While you may be able to use the wood without it becoming warped or damaged, getting a good warranty should protect you from any damage or additional costs. You should check the warranty coverage, such as rot and infection, and how long the warranty lasts. You should also look for a warranty that covers termites, because some treated woods are not resistant to termites, although they are resistant to other insects.
Pressure-treated wood is injected with chemicals, so it typically has more moisture than other woods. This excess moisture can lead to warping, rot and other problems over time, meaning the wood may not look good after a while or the project may fall apart as the wood warps, such as with decks. and the furniture. This means that it is normally best to get low moisture treated wood, such as wood that has been dried before being treated.
The chemicals that pressure-treated wood is exposed to can be harmful to both people and the environment, making it important to determine whether the wood is suitable for use above ground or for use in contact with soil. Above ground contact means that the wood will not touch or be in the ground and humans will be exposed to it. Wood in contact with the ground can be installed underground and must not harm the environment.
Pressure treated wood sometimes comes with extra finishing materials that can make it better for certain uses. You can find wood with a termite-resistant finish, coatings that make this wood better for staining and painting, and coatings that make this wood safer for human contact, among others. Such added coatings may cost more initially, but they can also make the wood more effective for your needs in the long run.
