I'm looking to build a wall in the basement. Basement exterior walls have concrete ledge so I'm planning to build a wall in front of it to build a straight wall floor to ceiling. I have couple questions:

  1. Since the exterior wall is already load bearing, the new wall in front should not be load bearing right?

  2. If the above is true, then can I frame the wall with screws and not nails? And can I use a 2 x 3 instead? Sole purpose of this wall is to hang drywall from floor to ceiling.

  • Any reason not to use nails? They are usually faster and cheaper. Can use screws and 2x3s, will want it anchored to the floor and ceiling. 2x4s might be nicer, less warp ones, more common. – crip659 Feb 08 '22 at 17:59

    Good Question: unless there is something in your local code preventing you doing that, it should be OK. From my point of view the only dumb questions are the ones that are not asked! – Gil Feb 08 '22 at 18:00

    @crip659, reason is I don't have a nail gun and want to avoid purchasing one if not absoultely necessary haha. Yes I'll be anchoring to ceiling and floor. Thank you for your answer! – basement_diy Feb 08 '22 at 18:02

    Not really an answer to your question but you might reconsider your stance on nail guns. Once you try one you will be hooked. – jwh20 Feb 08 '22 at 18:06

    Could also use a hammer and practice your lalochezia. – crip659 Feb 08 '22 at 18:17
  • For just one wall do not think a nail gun would be worth it, but they are very nice. If planning to do more nailing in the near future, I would definitely think about getting one. – crip659 Feb 08 '22 at 18:44
  • To make your new wall load bearing you would have to jack your house up off the foundation, make your new walls a tad higher and lower the house back on them, and for that you would need to build new foundations for your new walls. :) – jay613 Feb 08 '22 at 18:55

    Suggestion: Some basement walls leach moisture. It can be very slow, and you may never see it but if you cover it up it becomes a problem. Before covering your basement walls with drywall, tape a sheet of clear plastic 3 feet by 3 feet to the wall on all four sides, and leave it there for a few months, including a period of rain and/or snow melt. If the wall behind the plastic becomes darker or damp, you need to protect your interior walls from that moisture. – jay613 Feb 08 '22 at 18:58

I often use screws in such situations. Toenailing upside-down is not for the uninitiated. It's an exercise in frustration as:

  • it's physically demanding
  • things tend to jump around when you really don't want them to

I say toenailing because building walls on the ground and tipping them up requires a high level of measurement precision. Concrete floors are never flat, and you end up with either big gaps above or walls that require sledgehammers to get into position. Or both. So lay out your plates, install them, then measure studs individually.

I would qualify this by saying not to use drywall (black oxide) screws, which are brittle and don't tolerate bending. Almost any decent gold 3" screw would be fine.

  • And this is the use case for the 3" screws. Can't use them when attaching stuff to existing finished walls because there could be wires through the middle of studs, etc. But building new, 3" screws are really strong with no downside. – manassehkatz-Moving 2 Codidact Feb 08 '22 at 21:25
  • "Stuff"? If we're adding framing lumber to finished walls (1-1/2" thick) they're not too long. Did you mean household items? – isherwood Feb 08 '22 at 21:27

    I mean cabinets, standards for shelves, etc. Might have < 1" of stuff (or less) + 1/2" drywall - so a 3" screw will go more than 1-1/2" into a 2x4. – manassehkatz-Moving 2 Codidact Feb 08 '22 at 21:30

    @manassehkatz-Moving2Codidact The only downside is strength, which is why they're only an option for non-bearing walls. Nails are much tougher than plain screws. Softwood + nails is like concrete + rebar. Screws don't shear well at all, though, and they're quite brittle so under load they fail catastrophically like popcorn. There are listed structural screws, of course, but the downside there becomes cost. – J... Feb 09 '22 at 03:05

Sure you can use screws they would be stronger than nails. It’s a non weight bearing wall I have seen plenty toe nailed in place with 8 penny. Make sure to anchor the bottom plate and the top.

    Yes, screws are fine. Build the wall on the floor and then raise it with the help of a friend or two and then party...+1 – JACK Feb 08 '22 at 18:21
  • Non-load bearing is the critical phrase. You cannot frame bearing walls with screws. – J... Feb 09 '22 at 02:11
