Staining Exterior Rough Sawn Wood

Rough-sawn lumber adds a touch of rustic charm to your home’s exterior —and offers an opportunity to highlight the warmth and texture of natural wood. However, working with rough-sawn lumber differs slightly from staining and preserving smooth wood. Fortunately, the process isn’t difficult, especially when you follow the proper steps to get a long-lasting finish.

At DeckStainHelp.com, we’re experts at wood deck restoration, and we’re always glad to help homeowners with their exterior wood projects. Read our tips for staining rough-sawn wood, and you should have no trouble with the task! But if you have any questions, feel free to leave us a comment and let us help you.

Key Takeaways

• Prep properly – Sweep new wood; clean and brighten weathered wood before staining.
• Pick the right stain – Penetrating stains protect best; semi-transparent enhances grain, solid offers more coverage.
• Apply with care – Use a sprayer for the first coat, then a brush or pad for even coverage. Mask off areas to prevent overspray.
• Follow best techniques – Stain in 60-80°F weather, avoid rain, and choose wet-on-wet or wiping methods based on wood condition.
• Maintain regularly – Clean often and reapply stain as needed, especially in high-traffic or sun-exposed spots.

Rough Sawn Deck Trim

What Is Rough-Cut Lumber?

Rough-textured wood, also known as rough-sawn lumber, is wood that is used as originally cut: It has not been smoothed out or sanded like most lumber is. It’s becoming a more popular type of wood for homeowners and is commonly used for exterior wood fences, decking trim, and house trim. Typical wood types used are cedar and pine.

1. How to Prepare Rough-Sawn Wood for Staining

As mentioned, it’s possible to stain rough-sawn wood. However, the unique material may require a slightly different touch than smooth lumber. This is particularly true if you’re using new rough-sawn wood or if your rough-cut lumber has experienced significant exposure to the elements.

Generally speaking, you’ll need to clean and prep your wood before applying stain, but the process may vary depending on its age and condition. Learn more about how to treat rough-cut lumber for outdoor use.

2. New Wood vs. Weathered Wood

Planning to stain brand-new rough-cut lumber? You’re in luck! The prep process is fairly straightforward. Simply use a broom or a leaf blower to remove any dust or debris. Next, make sure the lumber is completely dry before applying stain.

The process may be slightly more involved if you have older stained rough-cut lumber that has experienced UV or moisture exposure. For older wood, we recommend a thorough cleaning. Start by applying a deck cleaner solution and letting it sit for 10 to 20 minutes before scrubbing the boards or pressure washing to remove dirt, mold, and mildew. When done, follow up with a wood brightener.

If you have an old stain that needs removing, use a wood deck stain stripper and pressure washing to remove it, followed by a wood brightener when done.

Penetrating vs. Film-Forming Stains

As the name suggests, penetrating stains soak into the open pores of rough-cut lumber, sealing the wood against moisture, grime, and UV damage. On the other hand, film-forming stains dry on top of the wood, similar to traditional paint. While film-forming stains work as a protective coating over wood, these types of stain can peel or flake more easily than penetrating options.

Solid vs. Semi-Transparent Stains

You may find both solid and semi-transparent options well-suited to rough-cut lumber. Solid stains bridge the gap between paint and stain, providing opaque, even coverage over your boards and concealing the natural wood grain. Due to their thickness, solid stains can provide the most UV and moisture damage protection. However, most solid stains form a film over the wood rather than penetrating the boards, which may lead to flaking and peeling. Alternatively, semi-transparent stains add a hint of color without entirely hiding the wood grain.

With all that said, we’ve found that a penetrating semi-transparent deck finish is the best choice for rough-sawn wood because it will soak into the wood more effectively, penetrating and sealing its pores.

Color Options to Consider

Some of our favorite stains for rough-cut lumber include natural tones like rich, chocolatey browns, honey hues, and redwoods. However, if you prefer a more opaque look, consider a solid gray or blue stone to create a beachy vibe or black and charcoal for a sleek, modern look.

4. How to Stain Rough-Cut Lumber: Application Tips

Are you getting ready to apply stain to rough-cut lumber? Consider the following tips to ensure an even application and a beautiful, long-lasting finish.

#1 Weather Considerations

Before getting started, check your local weather forecast and ensure it won’t rain for the next 12 to 24 hours. It’s also best to apply wood stain when temperatures are between 60 and 80 degrees. It should not drop below 32 degrees within 8 hours of staining. And try not to stain in direct sunlight.

#2 Surface Preparation

When staining rough-cut pine or cedar, it’s important to prepare the wood before application, as discussed above. If the wood is new, you can skip this step. Otherwise, use a wood cleaner to break loose any dirt, grime, and gray fibers. Then, wash the wood surface with a stiff brush or pressure washer.

If you have an old stain that needs removing, use a wood deck stain stripper and pressure washing to remove it, followed by a wood brightener when done.

Be careful not to use excessive pressure that could damage the wood surface. After using a wood cleaner or stain stripper, a wood brightener should be applied to neutralize the pH level and brighten the wood back to its original appearance. Note: If the wood is new, no prepping is needed and staining can be done right away.

Once the wood dries after cleaning, it’s time to stain.

#3 Application Methods

You can use a brush and/or stain pad to stain rough-cut lumber. A brush is good at getting into corners and cutting in along edges. Just be sure to opt for a stiffer brush instead of a soft paintbrush. A stiff brush will allow you to work the stain into the rough wood grain, especially in tight corners or detailed areas.

An exterior stain pad is best for pushing stain into the rough surface. Mask off any areas you do not want stained, and stain one board or section at a time to eliminate lap marks. Then, follow up with a brush to ensure even coverage in particularly rough or knotty spots.

Using a pump or airless sprayer, you can also apply most semi-transparent stains to rough-sawn wood. Spraying the stain can allow it to get into the rough texture of the surface with less effort than brushing or rolling. Just be sure to mask any windows, siding, concrete, and other surfaces in the area to avoid overspraying. In addition, start with a light first coat to avoid oversaturating the wood. If not, the stain may pool in uneven areas of crevices.

Our favorite method for staining rough-cut cedar or pine is to use both approaches. First, lightly spray on the first coat with a pump sprayer. This will absorb deeply, giving a nice base coat. We then follow up with a stain pad or brush to apply a second coat right away. This will ensure nice, even coverage.

#4 Coating Techniques

There are several techniques for applying stain, including the wet-on-wet technique and the wiping technique. With the wet-on-wet technique, you apply a second coat of stain before the first dries, allowing the stain to penetrate deeply into the wood boards. This is generally a better fit for dry, thirsty wood. The wiping technique involves using a rag to wipe away excess stain for a lighter application.

Regardless of the technique used, always follow the instructions on the stain label and wear proper personal protection. When you’re done applying the stain, use mineral spirits or soapy water to clean up all of your equipment and tools after staining.

5. Maintaining Rough-Sawn Lumber

Like any type of wood, stained, rough-sawn lumber requires regular maintenance to look its best. To avoid build-up and remove dirt and debris, clean the wood regularly.

Sweep the boards or use a stiff-bristled brush for tighter areas, and consider a deeper clean quarterly, if not every spring and fall. Finally, pay attention to the wood and reapply stain and sealant as necessary, especially in high-traffic areas or spots that receive direct sunlight. This will help protect the wood while maintaining the boards’ desired appearance.
