Choosing the Right Pressure Treated Wood
Building a deck or fence is a great way to improve your backyard. When you plan an outdoor project in Canada, you need wood that can stand up to our tough weather. Pressure treated lumber is the best choice because it is made to last. This wood goes through a special process that forces preservatives deep into the grain. This helps the wood resist rot, decay, and damage from insects. Whether you are building a small garden box or a large deck, using the right materials will help your project stay strong for many years.
There are many different types of pressure treated wood to choose from. Your choice depends on what you are building and where the wood will sit. It is important to pick the right rating for your project to ensure safety and durability.
- Pressure treated deck boards: These are designed for the surface of your deck. They are smooth and look great under your feet.
- Pressure treated posts: These are thick pieces used to support the weight of a structure. A 4x4 pressure treated lumber post is common for fence projects.
- Ground contact pressure treated lumber: Chemically preserved to a higher concentration than standard wood, allowing it to withstand direct contact with soil or fresh water without rotting or decaying.
- Pressure treated fence boards: Building a privacy screen or a yard border is easy with pressure treated fence boards.
Colours and Sizes and Sealing
You will often see green pressure treated lumber at The Home Depot, which comes from the copper used in the treatment of the wood. Over time, this fades to a warm grey. You can also find brown treated wood that looks more like natural cedar, usually called “cedar-tone” or “sienna”.
The most common sizes for pressure treated lumber are 2x4, 2x6, 2x8, 2x10, 2x12, and 5/4x6 (deck boards).
Remember that even though pressure treated wood is protected from bugs and rot, you still need to seal it, so it doesn’t warp, crack, or split.
