How to secure wall studs in a basement...?
I was tearing apart my old basement walls...on the concrete block, they used 2x4's ripped in half, and then nailed them into the concrete. They are very loose, and the wood along the floor is rotted in places, and I found a small area of the wall that was wet. I want to replace all this with pressure treated 2x4's and install like a regular wall so I get a thicker wall so I can insulate and keep away from the wall a bit. Is this a good idea, or is better to lay and nail onto the block? I am thinking maybe a 3 inch space to allow air space in there so any moisture on the wall can dry. And then I was planning on using dry lock on the wall for added protection. There has never been any free running water on the floor. So far so good?
If I build the fatter wall using the full width of the 2x4's, one issue I noticed is that on the ceiling joists I cannot nail into to secure the top header because a heating duct covers the joists the length of the wall. Any suggestions on how to anchor the top header? On the bottom header (if this is the name), I was thinking about using one of those nail guns.
Thanks to all so far with some other questions I had...
