My DD and SIL are looking to get an outside gym in Florida for the kids.
Anyone know which wood is better for this application.
LBYM route: ....
Also, remember, the kids will outgrow it in a few years, so it doesn't have to last longer than that.
73, go with pressure treated pine. Works great, is less expensive than redwood and no longer has the greenish coloration since the EPA "persuaded" manufacturers to phase out the use of Chromated Copper Arsenate (CCA) as a wood preservative.
Oh, but it's for the Chilllldren! NB: a splinter from pressure treated wood is nasty and doesn't like to heal until you get it all dug out. Regular wood makes for a happier splinter, less irritation, the splinter can camp out in your skin for a while. I've a redwood benchtop that is ~15 years old and is looking better than a PT railing installed at some apartments about 7 years ago.
