Acacia vs Teak Wood: Durability, Cost & Care Compared
Teak outlasts acacia outdoors: its natural oils resist rot, insects, and moisture for 20+ years with almost no upkeep, while acacia (Janka ~1700) is harder but needs oiling every 1-2 years to hold up outside. Skip that upkeep and acacia can gray, warp, or crack within 5-7 years — unsealed teak just weathers to silver and stays sound. This guide compares real hardness, price, and maintenance schedules side by side.
Quick Answer
For outdoor furniture, teak is the more durable choice — its natural oils resist rot, rain, and insects for 20+ years with minimal care. Acacia is harder (Janka ~1700 vs teak’s ~1000-1155) and costs roughly a fifth as much, but needs sealing or oiling every 1-2 years to last close to 10-15 years outside.
Acacia Wood Durability, Weather Resistance & Cost
Acacia is a dense hardwood popular for outdoor furniture and flooring thanks to its strength and affordable price. Its natural oil content gives it some built-in resistance to water and pests, but it is lower than teak’s — so acacia leans more on regular maintenance than on natural chemistry to survive outdoors.
Natural Resistance
Acacia’s dense grain and natural oils give it reasonable resistance to water and everyday moisture, reducing (but not eliminating) the risk of warping, cracking, or rot compared to softer hardwoods. It performs best when it gets a sealant or oil coat applied periodically rather than being left bare outdoors.
Pest And Rot Resistance
Acacia’s tight grain structure makes it reasonably difficult for termites, wood borers, and fungi to penetrate, which helps it hold its structural integrity in both indoor and outdoor use. That said, without periodic sealing, unprotected acacia left in wet, humid conditions typically shows fading, surface cracking, or mildew within about 5-7 years — want the longer-term picture?

Teak Wood’s Natural Oil Advantage
Teak is prized for outdoor and marine use because its own natural oils do the protective work that acacia needs a topical sealant for. That single trait — high internal oil content — is the real reason teak outperforms acacia outdoors over the long run, even though acacia is the physically harder wood.
Natural Oils
Teak’s dense grain is saturated with natural oils that repel water before it can soak in and cause rot or decay. These same oils slow UV fading, which is why teak wood is such a common choice for decking and boat building.
Insect And Moisture Resistance
Those same oils contain resins that deter termites and wood-boring insects, so teak wood furniture left outside rarely needs the pest treatments other woods do. Left unsealed, teak simply fades to a silvery-gray patina over a few years — a cosmetic change only, not structural damage. If you want to keep the original golden-brown tone, occasional oiling helps, but it is optional rather than required.
Acacia vs Teak Wood: Janka Hardness, Price & Maintenance Compared
Here is the nuance most comparisons miss: acacia is actually the harder wood by Janka rating, but hardness is not the same as outdoor durability. Teak’s advantage comes from its natural oil content, not raw density — which is why softer teak still outlasts harder acacia when both sit outside untreated.
| Factor | Acacia Wood | Teak Wood |
|---|---|---|
| Janka Hardness Rating | ~1,700 lbf (harder species up to 2,200+) | ~1,000-1,155 lbf |
| Typical Price | ~$10 per board foot | ~$50 per board foot (2-5x acacia) |
| Maintenance Frequency | Oil or seal every 1-2 years | Basic cleaning only; oiling optional |
| Typical Outdoor Lifespan | ~10-15 years with regular care | 20+ years, sometimes 40-50 |
📊 Teak’s Janka hardness rating sits between 1,000 and 1,155 lbf, while commercial acacia species run from roughly 1,700 up to 2,200+ lbf depending on species — acacia is the harder wood, but teak’s oil content is what actually wins the outdoor-durability contest. Source: The Wood Database, Teak.
Which Wood Should You Choose For Outdoor Furniture?
Choose acacia if you want a lower upfront cost and do not mind oiling or sealing your furniture every year or two — it is a solid pick for covered patios, milder climates, or furniture you plan to replace or refresh every 7-10 years anyway.
Choose teak if you want to buy once and mostly forget about maintenance — it costs several times more upfront, but its 20+ year lifespan with minimal care often makes its cost-per-year cheaper than acacia over time, especially for fully exposed decks or coastal patios.
“The mistake I see most often in the shop is people treating acacia like teak and skipping the oil coat — acacia can absolutely hold up outdoors, but only if you actually reseal it on schedule. Bare acacia left through a couple of wet seasons is where the cracking and graying shows up first, usually at the joints.”

Frequently Asked Questions About Acacia Vs Teak Wood
What is better, teak or acacia wood?
For outdoor furniture, teak is better long-term thanks to its natural oils, which resist rot and decay with minimal care for 20+ years. Acacia is the harder wood by Janka rating and costs far less upfront, but needs oiling or sealing every 1-2 years to come close to teak’s outdoor lifespan.
What is the downside of acacia wood?
Acacia can warp, crack, or gray within 5-7 years if it is not sealed or oiled regularly, since its natural oil content is lower than teak’s. Regular sealing and moisture control largely prevent this, but it does require ongoing upkeep that teak does not.
Is acacia wood high quality?
Yes. Acacia is a genuinely durable, dense hardwood (Janka ~1,700+) with attractive grain patterns, and it is often sourced from fast-growing, sustainably managed plantations. Its main tradeoff versus teak is that it needs more frequent maintenance to stay protected outdoors.
Which wood is better than teak?
Very few woods outperform teak for outdoor durability, though some tropical hardwoods like ipe and mahogany are comparably strong or harder. For most outdoor furniture buyers, teak remains the benchmark for low-maintenance longevity.
How much more does teak cost than acacia?
Teak typically runs about $50 per board foot compared to roughly $10 per board foot for acacia — a full furniture set in teak often costs 2-5 times more than a similar acacia set, though teak’s much longer lifespan can lower its cost per year of use.
Conclusion
Acacia and teak both make solid outdoor furniture — the real choice comes down to budget versus maintenance. Acacia costs a fraction of teak’s price but needs an oil or sealant coat every 1-2 years to last; teak costs more upfront but can go 20+ years with almost no upkeep. Match the wood to how much yearly maintenance you actually want to do.
