Why Protection Matters
Wood is organic, and nature is relentless. Rain causes swelling, drying brings cracks, and UV rays fade rich tones. Without protection, even hardwoods like teak and cedar will degrade over time.
Proper protection ensures:
- Longer furniture lifespan
- Better resistance to mold, rot, and pests
- Enhanced appearance
- Greater return on your time or investment
Step 1: Choose the Right Wood
Before you even apply a finish, protection starts with selecting durable, outdoor-friendly wood. If you’re building furniture yourself (especially with Ted’s Woodworking plans), choose species known for natural resistance.
Top Woods for Outdoor Furniture:
- Teak – High oil content makes it naturally weather-resistant
- Cedar – Lightweight and naturally repels bugs
- Redwood – Contains tannins that resist decay
- White Oak – Strong and durable, though heavier
- Acacia – Affordable and durable if properly sealed
Avoid softwoods like pine unless they’re pressure-treated or sealed thoroughly.
Step 2: Sand for Smooth Absorption
Start with a good sanding session. Even if your furniture is new, sanding removes surface impurities and opens up the wood pores to better absorb sealers and oils.
Pro Tip: Start with 80-grit and finish with 120-150 grit sandpaper. Focus on corners, joints, and flat surfaces.
Step 3: Clean the Surface
Before applying any protective product, ensure the furniture is dust-free and dry. For existing furniture, use a wood-safe cleaner or a solution of mild soap and water. Allow it to dry completely — moisture trapped under a finish can cause blistering or rot.
If your furniture has mildew or mold:
- Mix 1 part white vinegar with 3 parts water
- Gently scrub and rinse thoroughly
- Let it dry in the sun for several hours
Step 4: Apply a Wood Sealer or Outdoor Finish
This is where the real protection begins. Your choice of finish depends on the desired look, ease of application, and weather conditions in your area.
1. Exterior Wood Sealers
These are clear, penetrating finishes that allow the wood grain to show through. They prevent moisture penetration and help protect against UV rays.
Best for: Maintaining natural wood color
Apply every: 1-2 years
2. Oil Finishes (Tung, Linseed, Teak Oil)
Natural oils soak deep into the wood, replenishing lost oils and moisture. They’re easy to apply and enhance the wood’s grain, but require more frequent reapplication.
Best for: Rich, enhanced wood tone and texture
Apply every: 6–12 months
3. Exterior Varnishes or Spar Urethane
These create a hard, glossy surface film that offers long-term protection from moisture and UV. Look for marine-grade or spar varnishes designed for outdoor use.
Best for: High-gloss, durable finish on exposed surfaces
Apply every: 2–3 years (recoat as needed)
4. Outdoor Paints
Painting offers maximum protection, especially for softwoods. While it hides the wood grain, it forms a thick, weather-resistant shell.
Best for: Low-maintenance, colorful finishes
Apply every: 3–5 years

Step 5: Protect Joints and Undersides
Many people focus only on visible surfaces, but moisture creeps in from the bottom and joints. When building with Ted’s Woodworking plans, ensure all joints are sealed with outdoor wood glue and screws are rust-resistant.
Don’t forget to:
- Coat the bottom of legs and undersides
- Seal screw holes or hardware entry points
- Apply multiple coats in these vulnerable areas
Step 6: Elevate and Cover When Not in Use
Even the best finish wears over time. One of the easiest ways to prolong furniture life is preventative protection:
- Use outdoor furniture covers during storms or long winters
- Elevate legs with rubber pads to avoid pooling water
- Store furniture in a shed or garage during off-season
- Keep under a covered patio whenever possible
Step 7: Regular Maintenance
Outdoor wood furniture isn’t “set and forget.” Set reminders to:
- Reapply oil or sealer every 6–12 months
- Wipe down surfaces weekly with a damp cloth
- Sand and touch up scratched or worn areas
- Inspect for insect activity or signs of rot
Tip: Early maintenance is cheaper than full restoration.
Mistakes to Avoid
- Using Indoor Finishes Outside
Products like interior varnish or wax won’t hold up outdoors and can peel or mildew. - Skipping Undersides and Joints
Unfinished joints are a gateway for moisture and decay. - Neglecting Seasonal Changes
Humidity, rain, and sunlight shift with the seasons — adjust your care routine accordingly. - Assuming One Coat is Enough
Always follow manufacturer instructions — most sealers and oils require 2–3 coats for full protection.
