When done correctly, wood stain can add warmth, depth, and character to your projects, highlighting the unique grain patterns. While the basic steps of staining wood are straightforward, mastering the nuances of application makes all the difference between a mediocre and professional-looking finish. In the above video, This Old House DIY expert Jenn Largesse demonstrates proper techniques for applying wood stain to achieve a beautiful, long-lasting finish.
Tools and Materials Needed
For a high-quality wood stain result, you’ll need the following:
- Clean, lint-free cloths
- Clear protective topcoat
- High-quality brushes
- Pre-stain wood conditioner
- Sandpaper (120-grit and 150 or 180-grit)
- Sponges (optional)
- Tack cloth (optional)
- Wood stain
Safety Tips for Staining Wood
Staining wood involves using various chemicals and tools that often require proper handling for safety. Always work in an open area, and wear protective gloves and goggles to shield your skin and eyes from potential irritants. You should also wear a dust mask while sanding to prevent inhaling fine wood particles. Store all materials and chemicals safely and away from children and pets.
Ventilation Is Key
When working indoors, make sure that your workspace is well-ventilated. Open windows and doors to allow fresh air to circulate. You might use a fan to help disperse any fumes. Poor ventilation leads to respiratory issues and prolonged exposure to chemical vapors.
Protective Gear
Always wear the appropriate protective gear when staining wood, including the following:
- Clean dust masks to avoid inhaling sawdust and fumes
- Appropriate gloves to prevent skin contact with chemicals
- Safety goggles to protect your eyes from splashes and wood particles
Preparing Wood for Staining
Properly preparing the wood surface before applying any helps the stain adhere evenly and produces the cleanest-looking results.
Sanding the Wood
Sanding helps open up the wood grain, allowing the stain to penetrate more effectively. Here’s how to sand wood properly:
- Start with 120-grit sandpaper to remove any rough spots or imperfections.
- Wipe away the dust with a clean, lint-free cloth.
- Sand again with 120-grit sandpaper to further smooth the surface.
- Wipe the wood with a damp cloth to raise the fibers (optional).
- Perform a final sanding with 120- or 150-grit sandpaper.
For softer woods such as pine, you may want to finish with a higher grit (up to 180) to close the grain slightly and control stain absorption. However, avoid going beyond 180-grit, as this can prevent the stain from penetrating the wood effectively.
Cleaning the Surface
After sanding, clean the wood surface thoroughly. Use a clean, lint-free cloth to remove all dust and debris. Check that the cloth is truly clean to avoid pushing dust around or leaving fibers behind. For stubborn dust, consider using a tack cloth or vacuum with a brush attachment.

Applying Wood Conditioner
For softwoods such as pine and plywood, we recommend applying a pre-stain wood conditioner. This helps prevent blotchiness and provides even stain absorption.
When applying wood conditioner, timing is key. Apply the conditioner evenly across the wood surface. Allow it to soak in for 5–10 minutes and no longer than two hours. Wipe off any excess conditioner with a clean cloth.
Applying stain immediately after the conditioner can result in a watered-down, uneven finish. Patience during this step will lead to a more professional-looking result.
Staining the Wood
With the wood properly prepared and conditioned, it’s time to apply the stain. There are several ways to apply wood stain:
- Brushes: Ideal for flat surfaces and larger projects
- Cloths: Useful for thin pieces and avoiding drips along edges
- Sponges: Great for getting into grooves and tight corners
Applying the Stain
Whichever your method, follow these steps for a smooth application:
- Start with the most visible edges to prevent drips.
- Work in long, full passes on open areas.
- Check for even coverage across the entire surface.
- Avoid splattering or creating pools of stain.
Removing Excess Wood Stain
To avoid creating lines or streaks, fold a clean cloth with the edges tucked inside, then use the smooth fold to wipe in the direction of the wood grain. Make long, even passes across the surface. Resist the urge to keep wiping after removing the excess, as this can cause the stain to pull or become tacky.
Drying Time
Allow the stained wood to dry completely before proceeding to the next step. Some stains may dry faster, but it’s best to let the piece sit overnight to let the stain fully set. This ensures that the wood won’t lift or drag during the topcoat application.
Applying a Protective Topcoat to Complete the Staining
The final step in the staining process is applying a clear protective topcoat. This not only protects the stain but also enhances the wood’s appearance.
Choosing a Topcoat
There are several options for topcoats:
- Traditional oil-based polyurethane: This is durable, long-lasting finish with a warm, amber hue. It provides excellent protection against moisture, heat, and everyday wear and tear. However, it has a strong odor during application and drying, requires longer drying times between coats, and can yellow over time, especially in areas exposed to sunlight.
- Shellac: Shellac is a natural, nontoxic finish that dries quickly and adds a warm glow to wood. It’s easy to apply and repair, and it adheres well to most surfaces. However, it’s less durable than other finishes, susceptible to water damage and heat, and can be dissolved by alcohol, limiting its use in areas like kitchens or bars.
- Water-based polyurethane: This is a clear, fast-drying finish that maintains the natural color of the wood and has low odor, making it environmentally friendly and safer to use indoors. It’s easy to clean up with soap and water and resists yellowing over time. However, water-based polyurethane is not as durable as its oil-based counterpart.
Each has its advantages, so choose based on your project type and personal preference.
Application Tips
For the best results, follow these application guidelines:
- Mix the topcoat in a figure-8 motion to avoid creating bubbles.
- Use a high-quality brush for application.
- Apply the topcoat in long, even strokes following the wood grain.
- Avoid over-brushing, which can cause pulling and an uneven finish.
- Allow the first coat to dry completely.
- Lightly sand with 180-grit sandpaper and wipe away the dust.
- Apply a final coat for the smoothest, most professional-looking finish.
Common Staining Mistakes To Avoid
Even with the best preparation and precision, mistakes can happen. Here are some common pitfalls to watch out for:
- Ignoring drying times: Rushing through drying times can ruin a project. Each step requires drying time to set properly. Ignoring recommended drying periods can lead to smudged or uneven finishes.
- Inadequate sanding: Skipping or rushing the sanding process can lead to uneven stain absorption. Take your time to sand the wood surface properly, as this sets the foundation for a smooth finish. Using progressively finer grits of sandpaper can help achieve the best results.
- Uneven stain application: Applying stain unevenly can result in blotchy or streaky surfaces. Whether you use a brush, sponge, or cloth to apply the stain, strive for consistent coverage. Work in small sections to maintain control and efficiency.
Maintaining Your Stained Wood
Once you’ve achieved the perfect stained finish, take time to maintain it to keep your wood looking its best. Regular dusting and occasional polishing can help preserve the luster and durability of your stained wood.
- Polishing: Occasionally polishing your stained wood can enhance its appearance. Choose a wood polish that is suitable for your type of finish. Apply the polish with a soft cloth, following the wood grain, and buff gently to a shine.
- Regular dusting: Dust can quickly accumulate on wood surfaces, dulling the finish. Use a soft, dry cloth or a microfiber duster to remove dust regularly. Avoid using water or commercial cleaners that may contain harsh chemicals.
