Best Wood for Outdoor Furniture: Rot-Resistant Species, Joinery and Finishes That Last
Outdoor furniture fails at the joints and end grain long before the wood itself gives up. Pick a durable species, then build and finish so water can’t sit.
For outdoor furniture choose a naturally rot-resistant wood: teak and ipe are the most durable, western red cedar and cypress are light and affordable, and white oak is strong and decay-resistant. Avoid red oak, maple and untreated pine outside. Build so water drains away — sealed end grain, gaps between slats, raised feet — use waterproof glue and stainless or coated hardware, and refresh an exterior oil or spar finish every year or two.
- Use naturally durable species: teak, ipe, white oak, cedar, cypress — never red oak
- Rot starts where water sits: end grain, joints and feet
- Waterproof glue plus stainless or coated screws prevents failing joints and black stains
- Gaps, slopes and raised feet let water drain and wood dry
- Exterior oils need yearly refreshing; spar finishes last longer but must not crack

Outdoor furniture lives a hard life: rain, sun, frost and constant swings in moisture. The good news is that a well-chosen species and smart construction can last decades. The bad news is that the most beautiful indoor woods can rot through in a couple of seasons. Choosing the wood is half the job; building so it can dry out is the other half.
The best outdoor woods compared
| Species | Rot resistance | Weight / strength | Cost | Notes |
|---|---|---|---|---|
| Teak | Excellent | Medium, stable | Very high | Natural oils resist water; weathers silver; buy certified |
| Ipe and other dense tropicals | Excellent | Very heavy and hard | High | Hard on tools; pre-drill everything |
| White oak | Good to very good | Strong, heavy | Medium | Closed pores; great for chairs and benches |
| Western red cedar | Very good | Light, soft | Medium | Easy to work; dents easily; ideal for planters and chairs |
| Cypress | Good to very good | Light to medium | Low–medium | Heartwood is durable; sapwood is not |
| Mahogany / sapele | Good | Medium, stable | Medium–high | Beautiful; needs a good finish |
| Pressure-treated pine | Very good (treated) | Medium | Low | Let it dry; use compatible hardware |
| Red oak, maple, untreated pine | Poor | — | — | Avoid outdoors |
Use heartwood — the darker centre of the log. Sapwood of almost every species, even cedar and cypress, rots quickly. Browse durability ratings in our wood species database.
Why outdoor furniture really fails
Wood rots when it stays wet for long periods. A durable species buys you time, but the real enemy is trapped water:
- End grain soaks up water like a bundle of straws — the feet of a chair, the ends of slats.
- Tight joints hold water inside, where it can’t dry.
- Flat surfaces let puddles sit.
- Steel screws rust, stain the wood black (especially oak) and loosen.
Build it to drain and dry
- Seal the end grain with extra coats of finish or an end-grain sealer, especially on feet and slat ends.
- Raise the feet with plastic glides or a chamfer so they don’t sit in puddles.
- Leave gaps of about 1/4" between seat and table slats so water runs through.
- Slope horizontal surfaces slightly, and chamfer or round over top edges so water runs off.
- Use waterproof glue — Type I PVA, polyurethane glue or epoxy.
- Use stainless steel or exterior-coated screws. With oak, stainless is the safest choice to avoid black staining.
Check moisture content before you build. Lumber that is still wet will shrink after assembly and open up joints. A moisture meter takes the guesswork out.
Finishes for outdoor furniture
| Finish | Look | Maintenance | Best for |
|---|---|---|---|
| None | Weathers to silver-grey | Occasional cleaning | Teak, cedar, cypress |
| Penetrating exterior oil | Natural, warm | Re-coat every 6–12 months | Most hardwoods; easy to refresh |
| Spar urethane / spar varnish | Glossy film | Inspect yearly; sand and recoat before it cracks | Pieces under cover or partial sun |
| Exterior paint | Opaque colour | Repaint every few years | Pine and lower-cost woods |
UV light breaks down both wood and clear finishes. Finishes with UV absorbers last noticeably longer in full sun.

Questions woodworkers ask
Why can’t I use red oak outdoors?
Red oak has open pores that run along the board and wick water deep into the wood, and it has little natural decay resistance. White oak’s pores are plugged with tyloses, which is why it was used for barrels and boats.
Is pressure-treated pine good for outdoor furniture?
It resists rot well and is cheap, but it is often wet when sold, can warp and check as it dries, and is not ideal for surfaces where food is served. Let it dry thoroughly and use hardware rated for treated lumber.
What happens if I leave cedar or teak unfinished?
They weather to a silver-grey patina but stay structurally sound for years. A finish is mainly about keeping the original colour and reducing surface checking.
Which glue should I use for outdoor projects?
A waterproof glue such as a Type I PVA (for example Titebond III), polyurethane glue or epoxy. Standard interior wood glue fails when it stays wet.
How often should I refinish outdoor furniture?
Penetrating exterior oils usually need a fresh coat every 6–12 months in full sun. Film-forming spar varnishes last longer but must be maintained before they crack, or water gets trapped underneath.
