Refinishing outdoor wood furniture can breathe new life into old, weathered pieces and save you money compared to buying new. With some sanding, staining, painting, and sealing, you can restore your outdoor wood furniture to look like new. Here is a step-by-step guide to refinishing outdoor wood furniture.
Assess the Furniture and Gather Supplies
Before starting the refinishing process, carefully examine each piece of outdoor wood furniture. Look for areas of rotting or insect damage that may need repair prior to refinishing. Also check for any loose joints or hardware.
Once you’ve assessed the overall condition, make a list of all the supplies you’ll need. Here are some essentials:
- Sandpaper with varying grits (80, 120, 220 grit)
- Paintbrush, paint roller, paint tray
- Outdoor wood filler, wood glue
- Rags, paint thinner, gloves, drop cloths
- Outdoor paint and/or stain of your choice
- Outdoor polyurethane sealant (satin or gloss finish)
- Paint scraper, putty knife
- Orbital sander (optional)
Clean the Wood Surface
Before sanding, thoroughly clean the wood to remove dirt, grease, mold, mildew and old flaking finish. Here are some cleaning tips:
- Use a hose, power washer, or scrub brush with a deck cleaning solution
- Allow the wood to fully dry before sanding
- For mold/mildew, use a 50/50 vinegar and water solution
- Stubborn spots may need a bleach and water mix
- Rinse thoroughly after cleaning
It’s important to start with a clean surface for the new finish to properly adhere.
Sand the Furniture
Sanding removes the existing finish, smooths the surface, and opens the wood grain to accept the new stain or paint.
Work your way up with progressively finer grit sandpaper:
- Start with 80 grit to remove existing finish and level the surface
- Follow up with 120 grit to smooth everything out
- Finish with 220 grit for a silky smooth finish
Always sand in the direction of the wood grain. Thoroughly sand all surfaces – front, back, sides, and legs. Pay close attention to rounded edges or carved details. corners and crevices.
Use an orbital sander for flat surfaces or sand by hand for hard to reach spots. Completely remove all dust when finished sanding.
Repair Any Damage
Inspect the furniture again after sanding, and make any necessary repairs:
- Fill small holes, cracks, or dents with wood filler
- Use wood glue and clamps for loose joints
- Replace rotten or termite damaged wood as needed
- Allow repairs to dry completely before finishing
Proper repairs are essential for a long-lasting finish.
Apply Wood Stain (Optional)
For a transparent stained finish, apply your chosen outdoor wood stain according to the manufacturer’s directions. Here are a few tips:
- Use a high quality oil-based penetrating stain for best protection
- Stain a small hidden area first to confirm desired color
- Apply an even coat with a brush or clean cloth
- Wipe off any excess for a smooth finish
- Allow the stain to fully dry before sealing
Multiple coats may be needed for very weathered or porous wood. Lightly sand and wipe away dust between coats.
Paint the Furniture
For a painted finish, use a high quality outdoor paint primer followed by at least one coat of outdoor acrylic paint.
Priming:
- Choose an exterior primer specifically made for wood
- Apply an even coat with a brush or roller cover
- Allow primer to fully dry per manufacturer’s directions
- Lightly sand primed surface to ensure paint adhesion
Painting:
- Carefully follow paint manufacturer’s instructions
- Use smooth strokes with the wood grain
- Allow adequate drying time between coats
- Lightly sand and clean between coats for a smooth finish
- Apply at least 2-3 thin coats for best protection
A painted finish requires careful surface prep and application for lasting results.
Seal the Wood
The final step is applying an outdoor polyurethane sealant over stain or paint. This protects the finish and helps it last.
- Use an oil-based sealant made for exterior wood
- Carefully follow manufacturer’s instructions
- Apply 2-3 thin coats with a brush or roller
- Allow proper drying time between coats
The sealant provides an added layer of protection from moisture, UV rays and other outdoor elements.
Maintaining the Finish
With proper prep, application, and sealing, your refinished outdoor wood furniture can look great for years. Here are some tips for keeping it that way:
- Inspect furniture periodically for any worn spots or damage
- Sand and reapply paint or stain as needed
- Apply a fresh coat of sealant every 1-2 years
- Keep furniture covered or bring indoors when not in use
- Clean with mild soap and water only
A little maintenance goes a long way towards preserving your refinished outdoor wood furniture. Follow these steps, and you can enjoy beautifully refinished outdoor furniture for seasons to come.
Frequently Asked Questions
What’s the best way to remove old paint or stain?

What kind of paint should I use?
Choose a high quality acrylic latex paint made specifically for outdoor use. Oil-based paints are not recommended for outdoor furniture.
How long does it take for stain or paint to dry?
Drying times vary based on temperature, humidity and type of finish. Oil-based stains may take up to 24 hours to dry. Latex paints usually dry within 1-2 hours but may take longer in cool or humid conditions. Always follow the manufacturer’s recommendations.
Can I use a deck stain?
Yes, you can use high quality oil-based penetrating deck stains on outdoor furniture. They provide great UV protection and water resistance.
What kind of sandpaper is best?
Use aluminum oxide sandpaper as it resists clogging and works on both wood and paint. Start with 80 or 100 grit to remove finishes, then 120 and 220 to smooth and prep the surface.
