Sister Studs in Ceiling (Easy Question)
So I took the drywall out of all the walls and ceiling because I have to re-rock and tile the upstairs bathroom. I have done this once before in the downstairs bathroom and it was successful. In the downstairs bathroom there are joists and it was pretty easy to hang the rock on the celing.

Now, for the upstairs, it is a relatively new addition put on by the former owner of the home - 10 year old addition.

My question is: when I removed the rock from the ceiling I did not find joists - I found 2x4s and they were a little loose but the wood is in good shape. Should I just sister these 2x4s? The roof of the house is on a slight slant which is why I don't think there are joists. Very odd to see 2x4s but I think the concept is the same - just use drywall screws and screw them in at about 6 inches a part, or sister the studs in the ceiling and go 8-10 inches apart. Thoughts?

How big is the ceiling we are talking about?

2x4 joists has me :huh:

8ft x 4ft

I hope they are spanning the 4' section?

yes, absolutely. They run the length of the room in terms of length and width. It just seemed odd when I took the rock off the ceiling and saw 2x4s. I thought I would be dealing with joists. I am sure it is okay but the studs seemed a little "wobbly" even though the wood seemed relatively new.

Sister studs is what I initially thought of. Thanks in advance for the help

It wouldnt hurt to sister 2x4's to the joists.

Do you have enough room to make an L with another 2x4 on every joist?

t3rdeyevisual 09-07-2007 06:08 PM

yes, I do. Good idea. This will not make them more "wobbly"?

It will strengthen them.

well, thank you. I will let you know how it works out.

You could also use blocking to unitize the ceiling. Add 2x4 blocking so the span is cut into thirds. This will eliminate any wobble.

Ron, I don't quite understand. Can you elaborate a little bit in detail? Is there a picture somewhere that I can look at?

Ron6519 09-08-2007 01:47 PM

I don't have pictures, sorry. Blocking are short pieces of wood that connect the long 2x4's together. You put three pieces per bay and nail them to the 2x4 joists.
If someone doesn't come along with some graphics, just do a search of framing.
