When it comes to maintaining your exterior wood surfaces, you might think the job is as big as the outdoors itself. But here’s the truth: protecting your deck, fence or even that handcrafted wooden bench doesn’t have to be a hassle.

Ready to create vibrant open-air spaces with ease? It's as easy as 1-2-3 with Thompson’s® WaterSeal®. Just follow these three simple steps to enjoy beautiful, protected wood that lasts!
 

Before you dive in, take a little time to prepare. Just like a good foundation is essential for a strong house, proper prep ensures your waterproofing treatment goes on smoothly and stands up to the elements.

Surface Cleaning

Start by giving the wood a thorough cleaning. This isn’t just about appearances; dirt, mildew and blemishes can prevent sealants and stains from properly penetrating. Use Thompson’s WaterSeal Heavy Duty Deck Cleaner with a pump-up sprayer for an even application. Then, grab a stiff-bristle brush to work the cleaner deep into the wood. Wait 10 to 15 minutes and rinse it off. If you see any stubborn spots, don’t be shy—give them another scrub.

Patience pays off! Let the wood dry for at least 24 hours before diving into the next step. It’s worth the wait for a stronger, longer-lasting seal. 

When you’re ready to seal the deal, a combination wood stain and sealant is your best friend. It doesn’t just protect the wood; it can also add a touch of color to enhance your outdoor space’s natural beauty.

Choosing the Right Product

Now, you’ve got options—water-based or oil-based, tinted or clear. Water-based products are easier to clean up, dry faster and can be applied to both dry and damp wood. On the other hand, oil-based sealers penetrate deeper into the wood, providing longer-lasting protection, which is great for older or more porous surfaces.

Choosing between a clear or tinted finish is also important. Clear sealers maintain the wood’s natural look while providing water and UV protection. Tinted sealers, however, add some color and extra UV defense, letting you customize the appearance of your outdoor space.

Considering this, it’s key to match your choice of product to the specific condition and needs of your deck, fence, or outdoor furniture. Thompson’s WaterSeal Clear Wood Sealer gives a natural finish with added UV protection, perfect for a minimalist look. For shaded areas or those that receive less direct sunlight, Thompson’s WaterSeal Waterproofing Stain – Semi-Transparent is a great choice. It offers mildew-resistant protection plus a semi-transparent finish that adds subtle color while allowing the wood grain to show.

When Applying Stain and Sealer

• Timing Is Everything: Wait for a dry day in the 50 F to 85 F range. Don’t seal if there’s a chance of rain in the next two days or if it’s extremely hot. Applying on a cloudy day is even better since it slows the drying time, allowing the coating to be absorbed more deeply.

• Size up the Job: Go with the right tool—brushes for trim and tight areas, rollers for open spaces and sprayers for large jobs or hard-to-reach spots. Adjust your approach based on the texture and condition of the wood. Work in sections (~60 sq. ft.) to keep things even and avoid overlapping, and so the stain stays wet so you can blend it smoothly.

• One Coat or Two: One coat is usually enough, but if you want a deeper color, let the first coat dry for two hours and apply a second within four hours.

You’ve done the hard work, but to keep your outdoor surfaces looking their best, regular maintenance is key. Waterproofing isn’t a “one-and-done” project—it’s more like a maintenance partnership.

Routine Care

Regularly sweep off dirt, leaves and debris to prevent mildew from building up. Use a mild cleaner if needed, and give your wood a gentle rinse every now and then to keep it fresh.

Reapplication Timing

Depending on your local climate and how much sun or rain exposure your surfaces get, reapply waterproofing every two to three years. The splash test is a quick and easy way to check if your wood is ready for another coat.

Thompson’s WaterSeal products don’t just get the job done—they do it exceptionally well. These stains and sealers exceed industry standards for water repellency, meaning you’re getting the best protection for your outdoor surfaces.
