Choosing a Stain
There are a few main types of wood stains to consider for your project:
- Pigmented stains contain pigments suspended in a vehicle and come in various opacities. They tend to fully obscure the natural wood grain.
- Dye stains are translucent and bring out the depth and character of wood grain rather than obscuring it.
- Gel stains combine pigment and dye for controlled transparency over wood grain.
Factors like the color, finish and wood type will inform your staining decision. Take into account whether your project will be used indoors or outdoors as well.
Be sure to test different stains on scrap pieces of wood to compare colors. Common mistakes like applying too much stain or failing to adequately prep the wood can ruin a project. Careful prep and small test samples are key for success.
Prepping and Sanding Wood
Proper preparation is crucial before staining. Clean wood with a cloth dampened in paint thinner to remove grease, wax and dirt. Sand using progressively finer grit sandpaper up to 220- or 320-grit. Always sand with the direction of the wood grain.
Using wood conditioner allows for a more even stain application. Conditioners help prevent blotchiness by evening out differences in wood porosity before staining.
Preparing the Wood Surface
Adequate prep before staining includes:
- Cleaning and sanding as detailed above
- Noting wood grain direction and sanding accordingly
- Using wood conditioners on soft or porous woods
- Filling any cracks, holes and defects with wood filler
- Controlling wood moisture content
Wood conditioners allow for a more even stain application by evening out differences in wood porosity before staining. Apply per manufacturer instructions.
Use wood filler to patch cracks, holes and defects according to filler specifications. Allow proper cure times before sanding smooth. Controlling wood moisture also helps condition wood for staining – let wood acclimate to your shop and monitor with a moisture meter.
Additional Prep Tips
Additional tips:
- Use painter’s tape to mask off areas you don’t intend to stain
- Wear gloves to avoid transferring skin oils onto unfinished wood
- Use tack cloths after sanding to pick up remaining dust
Applying the Stain
Before starting, be sure you have the necessary staining supplies on hand:
- Rags, foam or bristle brushes
- Stir sticks
- Paint sprayer (optional)
- Paint thinner for cleanup
Carefully follow the manufacturer’s instructions for application – methods can vary greatly by product. In general:
- Stir stain thoroughly before and during application
- Use a foam brush or lint-free rag to wipe on stain
- Apply stain evenly with the wood grain
- Allow appropriate drying times between coats
Applying too much stain can create an uneven, blotchy appearance. Wipe in the direction of the wood grain using a clean rag before stain dries. Two to three thin coats typically works better than one heavy application.
Brushing and Spraying Techniques
For large surfaces, consider using a high-quality brush made for oil-based stains. Use light, even strokes following the direction of the wood grain. Rushing can cause drips and blotchiness.
Spraying stain requires some skill but creates a very uniform appearance. Use narrow spray patterns, hold the sprayer perpendicular and spray exactly parallel to the wood grain. Practice first on scrap material.
Allow full drying between coats as directed by the manufacturer. Cool temperatures or high humidity can extend dry times. Rags soaked in stain can combust, so lay flat to dry or soak in water before disposal.
Protecting the Finish
Once stained, protecting the wood finish is highly recommended both for appearance and to prevent damage:
- Sunlight causes fading, yellowing and accelerated aging of wood and stain colors
- Water leads to discoloration, raised wood grain, white spots, warping and rot
- Scratches and dents physically damage the finish
Using a clear protective finish helps guard against these threats. Consider where your wood project will live – indoors or exposed to the outdoor elements? This informs the type of protective finish to use.
Types of Clear Protective Finishes
Common topcoat options include:
- Oils – Penetrating oils like tung and linseed soak into wood pores without leaving a surface film. Minimal protection but easy to apply and maintain.
- Waxes – Used over oil finishes; mild water resistance and sheen. Soften over time requiring regular reapplication.
- Varnishes – Durable surface film for basic protection against moisture and spills. Slight amber tone.
- Polyurethane – Extremely hard plastic-like film shields from abrasion and liquids. Can feel artificial.
- Spar varnish – Flexible for expanding/contracting exterior wood. Formulated to withstand sun exposure.
Consider rub-on oils and waxes for a natural look on indoor projects. Use brushing varnishes on high-use indoor items. Opt for wipe-on polyurethanes and spar varnishes for outdoor furniture, doors and trim.
Always check finish instructions regarding prep, compatible underlying products, application tools, dry time and cleanup. Applying multiple coats ensures full, even coverage and optimal protection. Lightly sand between coats to ensure proper adhesion.
Caring for the Finish Over Time
The final step for a showpiece project is sealing and maintaining that perfect finish for years to come. Use paste wax to seal wood after the last coat of protective finish cures. This adds water repellency, sheen and protection from spills and fingerprints:
- Clean wood surface
- Apply paste wax in thin, even coats per label
- Buff off excess after drying
For general finish care:
- Avoid direct sunlight to minimize fading
- Quickly wipe spills to prevent stains
- Use furniture coasters under hot and wet items
- Apply fresh wax coats every 2-3 years
- Spot clean wax buildup with mineral spirits
- Lightly sand and reapply polyurethane as needed
Especially for outdoor projects, seasonal maintenance helps your woodwork hold up for decades against the elements. Inspect wood for raised grain, mold or mildew, splinters and other issues a few times per year:
- Spring – Examine for winter damage, lightly sand, clean, apply protective finish if bare spots appear
- Summer – Wash away pollen, mold, and bird droppings
- Fall – Clean leaves and debris, cover/store furniture over winter

Frequently Asked Questions
What are some beginner wood staining mistakes to avoid?
Some common wood staining mistakes beginners make are not adequately prepping the wood, failing to test stain on scraps first, applying too much stain leading to an uneven or blotchy appearance, staining across the wood grain, and not allowing proper drying time between coats.
How do I get a smooth, professional stain look?
Achieving a smooth stain finish requires proper sanding up to at least 220 grit, using wood conditioners on soft/porous woods, applying thin coats of stain with the wood grain using foam brushes or lint-free rags, allowing adequate dry time between coats, and finishing with protective topcoats.
What is the most durable protective finish for outdoor wood projects?
Spar varnish is formulated to best withstand sun exposure, wood expansion and contraction, temperature changes and moisture for exterior wood projects. Marine spar varnish provides maximum water resistance.
Should I finish wood before or after assembly?
It’s generally best to stain and finish all wood components before final assembly. This allows for easier access to all wood surface areas. Precut all joinery first, finish parts individually, allow full curing, then gently sand any areas glued for final assembly.
How long does it take for wood stain and finishes to fully cure?
Cure times vary widely by product but expect wood stains to fully set in 24-48 hours assuming 70°F temperatures. Oil-based finishes take up to 2 weeks to fully harden through solvent evaporation. Water-based products dry faster initially but take 30 days to fully cure after the final coat.
Can you restain wood without completely removing the old stain?
In most cases, you can apply fresh coats of stain over an existing stain without fully removing it. Lightly scuff sand the surface, wipe clean, then apply stain in thin, even coats. Multiple thin coats typically adhere and look better than trying to obliterate the old stain in one thick coat.
What’s the best way to revitalize a wood finish that has faded or lost its luster over time?
To refresh faded wood finishes, clean the surface then apply paste wax in thin, even coats using 0000 steel wool. Allow to haze and buff out with a lint-free cloth. For extra faded white water rings or spots, medium to fine sand those areas before waxing the full surface. Reapply protective finishes like polyurethanes as needed.
