If you have a pressure treated wood deck, then you know how important it is to maintain it properly. Deck sealers play a crucial role in protecting your deck from the elements and keeping it looking great. However, choosing the right deck sealer for pressure treated wood can be a daunting task. In this article, we will provide you with a short guide on the key points to consider when looking for a deck sealer for pressure treated wood.

1. Type of sealer: There are two types of deck sealers; water-based and oil-based. Water-based sealers are eco-friendly, easy to clean up, and offer a clear finish. Oil-based sealers, on the other hand, are more durable, offer a natural finish, and require more time to dry.

2. UV protection: Look for a deck sealer that provides UV protection. This is important because the sun's UV rays can cause the wood to fade and lose its color.

3. Mildew and mold resistance: Moisture can cause mildew and mold to grow on your deck, which can be hazardous to your health. Therefore, choose a deck sealer that is mildew and mold resistant.

4. Durability: A good deck sealer should be durable enough to withstand foot traffic, weather, and other environmental factors.

5. Application method: Consider the application method of the deck sealer. Some sealers require a sprayer, while others can be applied with a brush or roller. Choose a sealer that is easy to apply and suits your preference.

In summary, when looking for a deck sealer for pressure treated wood, consider the type of sealer, UV protection, mildew and mold resistance, durability, and application method. By keeping these key points in mind, you can choose a deck sealer that will protect your deck and keep it looking great for years to come.

Best Deck Sealer For Pressure Treated Wood FAQs

Are there any special considerations when choosing a deck sealer for pressure treated wood in a humid or wet climate?

Yes, there are special considerations when choosing a deck sealer for pressure treated wood in a humid or wet climate. The sealer should have excellent water repellency and resistance to mildew and mold growth. It should also provide UV protection to prevent the wood from fading or graying due to exposure to sunlight. It is recommended to choose a sealer with a high solid content as it will provide better protection and last longer. Additionally, the sealer should be able to penetrate the wood deeply to provide long-lasting protection against moisture and decay. It is also important to consider the application process, as some sealers may require multiple coats or special preparation before application. In summary, choose a sealer that provides excellent water repellency, resistance to mildew and mold, UV protection, high solid content, and deep penetration.

Can I apply a deck stain over a deck sealer on pressure treated wood?

Yes, you can apply a deck stain over a deck sealer on pressure treated wood. However, it's important to note that the sealer may affect the stain's ability to adhere to the wood surface. Therefore, it's essential to ensure that the sealer is completely dry and has not formed a film barrier before applying the stain. If the sealer has formed a film barrier, it will prevent the stain from soaking into the wood, causing it to peel or flake off over time. It's best to test the compatibility of the sealer and stain on a small inconspicuous area before applying it to the entire deck surface. Additionally, it's crucial to follow the manufacturer's instructions for both the sealer and stain to achieve the best results.

How do I prepare pressure treated wood for a deck sealer application?

To prepare pressure treated wood for a deck sealer application, you need to follow these steps:

1. Clean the wood: Use a pressure washer or a scrub brush to clean the wood surface thoroughly. Remove any dirt, mildew, or debris from the wood.

2. Let it dry: Allow the wood to dry completely before applying any sealer. This can take anywhere from a few hours to a few days, depending on the weather conditions.

3. Sand the wood: Use a sander to smooth any rough spots or splinters on the wood surface. This will ensure that the sealer adheres properly and provides a smooth finish.

4. Apply the sealer: Use a brush or a roller to apply the sealer evenly on the wood surface. Make sure to follow the manufacturer's instructions regarding the number of coats and drying time.

By following these steps, you can ensure that your pressure treated wood deck is properly prepared for a sealer application and will look beautiful and last for many years to come.

How often should I apply a deck sealer to my pressure treated wood deck?

As a general rule, you should apply a deck sealer to your pressure-treated wood deck every one to three years, depending on the type of sealer used and the amount of foot traffic on the deck. If you notice that water is no longer beading up on the surface of your deck, it may be time to reapply the sealer. Additionally, if you see any signs of fading or discoloration, it may also be time to reseal your deck. It is important to keep your deck properly sealed to protect it from the elements and to extend its lifespan. Be sure to follow the manufacturer's instructions for application and use a high-quality sealer to ensure the best results. Regular cleaning and maintenance can also help prolong the life of your deck and keep it looking great for years to come.

What is the best type of deck sealer for pressure treated wood?

The best type of deck sealer for pressure treated wood is a penetrating oil-based sealer. This type of sealer penetrates deep into the wood, providing protection against moisture and UV rays while allowing the natural beauty of the wood to shine through. Look for a sealer that contains UV inhibitors and mold/mildew inhibitors for added protection. It is important to choose a sealer specifically designed for pressure treated wood, as it has unique properties that require special attention. Avoid using a film-forming sealer, such as a solid stain or paint, as it can trap moisture and cause the wood to rot. Be sure to properly prepare the wood surface before applying the sealer, including cleaning and possibly sanding, to ensure maximum adhesion and effectiveness of the sealer.
