Shed Floor, Exterior Plywood or PT?

JohnHens | Posted in General Discussion on May 3, 2006 02:20am

I have to build a shed. Rather than pour a slab , I am going to set it on concrete blocks. The shed will be 10’x10′.

I am not sure what to use for the floor.

Would exterior grade plywood T&G be sufficient or would I be better off with Pressure Treated Plywood. I would like to use Exterior Grade assuming I can get T&G.

The floor will be framed with PT.

What about putting 30# felt on top of the floor frame and putting down regular 3/4″ T&G?

Thanks

John

    My garden shed is up about 16" at the gighest corner on pier blocks and 6x6 stubs; treated floor framing and 3/4" T&G CDX - seems fine after a couple of years - just make sure it's high enough for air circulation under it.

      I use treated 4x4 sleepers and 2x bridging to make the floor frame. I set mine on a concrete slab. I then staple 6 ml poly over the frame and then use standard 3/4 exterior grade plywood on top of that. Then I set my bottom sills, on that the 2x studs, etc. This keeps moisture from the Ply, and out of the shed.

    3/4 cdx is fine.  Like the other post said, just keep it up off the ground for some air circulation and you'll be fine.  The plywood is never going to see any water which is what you would need the pt for.

    I'm surprised that no one has asked where you are. If you are going to ask questions here, you'll make it easier on those who might help you if you fill out your profile.

    If you live in the bone dry west, use cdx and framing lumber and don't worry about ventilation, if you live in a damp climate (Florida, western Washington, etc.) go for treated joists and treated plywood, most places you can get by without treated anything if your framing is 16" off the ground.

    Do you plan to attach this shed to the ground? How windy is the location of the shed? Where I live the wind blows a loaded semi off the interstate several times a year!

      I am not sure what Profile you are referring to??

      I live in NE IL, about 45 miles west of Chicago.

        Hiya John, has was referring to the BT profile you can fill out a little that is seen after you click on your blue hilighted name in the To: or From: listing of this post.

        Will you be driving a mower or anything into this shed?

            Ok, was just wondering.

            I like to put the sheds up above the ground a few steps for extra storage underneath is all.

          rez, one day you gotta teach me how you insert stuff like that. I can never do it right. And where did the sandbox disappear to.

            You know how to copy /paste somthing?

          2. Lansdown | May 03, 2006 06:51am | #11

            Yes
            Though I am using Firefox, so that makes it a little more involved.
            But are you attaching (uploading) an image or just cutting and pasting?
            You don't have that little telltale icon for an attached picture.

            That example of the 'From:John' was just a copy/paste from his reply beneath the new post I was making, scrolling down: hilighting and copy: scroll back up and paste.

            Oh, you're looking for the hilighted blue name that serves as a link to be copied and pasted and still work as a link.

            Yeah, must be the programing of the browser.

            If you went from what is this? an IE Browser?  to the Firefox or whatever, I would think that the IE is still in yer files and accessible if you just wanted to try it and see.

            I had Firefox for a while then went back to IE and the Firefox is still in the files and accessible to turn on if desired.

             

            be I think I know what a browser is.

            Eureka, it works with IE.

            Both Luka and Jon Blakemore tried to explain the code language that needs to be entered in Firefox, but I still can't get it.

             

            Be I'll be back to IE during BT

    You could probably get away with the untreated ply if you design in decent overhangs and flashing at the base to deal with splash-back.  Plywood tends to rot from the edges where the end-grain is exposed.
