I'm looking to paint a few outdoor signs for our property. They will be about 2'x1' and screwed to a tree or wood post.

What type of plywood is best for something like this?

Thanks!

Plywood.

Something else. Maybe treated pine, or oak, if you're gung ho

Good question.

I'd hope it will last in the 3-5 year range.

Really should have simply asked what type of wood.

Not OB ready. Painted plywood?

Correct answer is carved Teak, Cyprus, or Ipe carved by Agrams.

if you are going to paint them and they won't sit in water, their durability relies more on the paint than the wood.

though for ease of carving and good weather resistance, true mahogany is good (Honduran, not African, sipo, khaya, or one of the other dozens of species sold and labeled as mahogany).

If you are talking about total exposure to the elements and looking for longevity do aluminum that's painted.
See…. Street signs.
As another poster said. On wood it's more about proper surface preparation, proper priming and proper base coat.

This question sent me down the rabbit hole as to what the state parks do for their signs. The answer is apparently "treated lumber", and they last 6-8 years, according to this video.. I don't know wood, I'm guessing pine.

Video below is about the guy who made all the signs for Texas State Parks at the time. He appeared to have an Aggie Ring, and his name matches a 1995 grad in Rangeland and Ecology Management.

Outdoor grade plywood or wood siding, painted, will last a decade or more. You can go treated if you need more longevity but no reason to go overkill. It's a sign.

Find something called signboard. It's a thing made for that.

Back when I started my career in plywood manufacturing (1988) we produced a 3/4 AA marine grade that was used for highway signs. An A grade face has no defects such as splits or knots, and the core line had to be perfect with no laps or gaps.

BS 1088 or BS6566. Usually made with Meranti or Okume mahogany and doesn't easily split or check. Light, extremely strong, sands well, and water won't damage it for decades. It's also extremely expensive. I used it in my boat and kayak builds. Worth every cent in boat construction.

Facility signs at my old state office are treated pine 2x10, they are at least 30+ years old and get a new coat of exterior latex every 6-8 years.
