Now that I'm retired and back from an Alaskan cruise, I've started to work on putting my 12x18 shed/shop together. Question is whether OSB (cheaper than PW) will work in the So. Florida humidity for interior walls and ceiling. The wall studs and trusses are 2x4 on 16" centers and will be insulated using R-15 faced insulation. It will also have a 1 ton ductless mini-split AC unit and I will also be painting the walls and ceiling.

Thanks in advance for your help.

Thanks Chuck. How many coats of primer & paint did you use?

Thanks Tom. It may be that OSB is the way to go. It's about $350 for the 1/2" OSB and $515 15/32" PW. Saves me ~$150 that I can use for insulation, paint, or tools.

Thanks for all the replies guys. Only issue with OSB I found in my searches was it's not water friendly as plywood is, so a undetected leak could be a major issue. Like DRTom I'm also using R-13 and will look at the radiant barrier as well. I have eight linked 4' 2 bulb LED lights being installed in the ceiling a four bulb 4' LED along one wall and three 3' LED along another wall so I may not need to paint the walls or ceiling if it will light it up. May be just seal it. But then again, I may end up painting it. Who knows.

Again, many thanks for the assist.

Thanks for the post Steve. I like the idea of adding a 1" pleated filter in front of the indoor unit and will be looking into making or possibly buying one, if available. I hope the WEN air filtration unit that I'm installing helps with the dust. To help with the temperature I'm installing a radiant barrier under the R-13 faced pink stuff. Should help with the sun issue here in So. Fla.I'll be talking to HVAC guy about that filter when he comes to install the unit.

Funny how things go. Just when you think you've created the the best plan to get your shop up and running, you run into stuff that prolongs the process. I'll get progress pictures as I get really moving.

The electrical should be done by the weekend by a licensed/certified electrician. I have a 60A breaker in the main panel in the house and had a 6/3 wire run through the attic to a junction box outside the house and in front of the shed. He's running 6g THWN wire underground in a schedule 40 conduit into the old 150A house panel I'm using in the shed, then 12/2 & 14/2 Romex to the outlets. The 110v/ & 220v circuits are going to be on 20A breakers with each of the 6 220v outlets on individual circuit breakers. The 110v outlets will be split into 5 circuits - main lights, supplemental lights, air filter, AC (the mini unit is 115v), and 6 outlets.

I've decided to go with 3/8" plywood. I found it to be the best option for me. I'm going to prime and and paint it.

Now for attaching the ply to the studs I've been debating whether to use 2" deck screws or getting the Hitachi NT 65MA4 DA 15g finish nailer. The nailer would be faster than the screws but then would I need a nailer if I'm not going to do base boards, trim, or crown molding work. I already own an 18g brad nailer and a 23g pin nailer. Is there a benefit from having a 15g nail gun in addition to the other two I already own.

Thanks for the advice.

BTW, I'll post pics of the shop build when I get most of it done. I'm taking pics as I go along.
