Can I stain my pressure treated deck?

Yes, and you definitely should. Pressure treated wood is a popular and cost-effective material choice for decks. There are several benefits to staining it:

Extended lifespan:
Pressure treated wood is naturally resistant to rot and decay, thanks to the chemicals used during the treatment process. But staining the wood provides an additional layer of protection against moisture, UV rays, and other environmental elements. This extra protection can significantly extend the life of your deck, saving you money on repairs and replacements in the long run.

Enhanced aesthetics:
Pressure treated wood has a utilitarian appearance that may not suit everyone’s taste. Staining allows you to enhance the deck’s visual appeal by adding color and character that complements your outdoor décor. Whether you prefer a natural wood look or a more vibrant hue, staining provides countless options to personalize your space.

Weather resistance:
Outdoor wood surfaces are constantly exposed to changing weather conditions. It’s especially relevant with the changing of the seasons here in Canada. Staining creates a barrier that helps prevent water penetration, reducing the risk of warping, cracking, and splitting. It also helps prevent the wood from fading and graying over time.

Choosing the right stain:
When selecting a stain for your pressure treated deck, it’s essential to consider the type of stain that best suits the wood’s properties. While any outdoor stain can be applied, oil-based stains are particularly effective for pressure treated wood.

Oil-based stains:
Oil-based stains are renowned for their deep penetration into the wood fibers. This is particularly advantageous for pressure treated wood, as it ensures the stain forms a robust protective layer within the wood. This layer prevents water from seeping in while allowing the wood to breathe, reducing the risk of moisture-related issues.

Latex vs. oil-based stains:
While latex-based stains are suitable for some applications, they tend to form a surface film that can peel or crack over time. Oil-based stains become an integral part of the wood, offering longer-lasting protection and a more natural finish.

Application and maintenance:
Staining a pressure treated deck is a straightforward process that can be accomplished with a few simple steps. Before you start, ensure the wood is clean, dry, and free from any previous finishes. Apply the stain using a brush, roller, or sprayer, following the manufacturer’s instructions. Allow adequate drying time between coats for optimal results.

To maintain the stain’s effectiveness, regularly inspect your deck for signs of wear and reapply the stain as needed. A well-maintained stain will keep your pressure treated deck looking its best for years to come.
