Just moved into my house. The garage has drywall hung. The seams of sheets slope down towards each other. It's my understanding you mud and tape these to paint etc.

The problem is, at the seam, one sheet is secured to the stud. The other is essentially floating.

To my understanding they were supposed to screw a secondary backer beam into the stud which the other sheet secures to so both sheets could be secure at the seam.

Other wise when you paint etc it's going to flex at the seam from various things and crack.

Anyway to resolve this without taking all the sheets down to put a backer and reinstall ?

Thanks.

 

Welcome to the forums.

Whoops..... the two sheets are supposed to end up with the seams in the center of the stud.

Are you sure there's no nothing there ?
Have you tried pushing in gently on the sheetrock to see if it hits anything ?

That extra piece of wood would be called a nailer. A place where the sheetrock could be fastened to. If the sheetrock isn't fastened securely the seam will crack after finishing.
Pretty hard to install now without pulling the sheetrock down.

 

Hard to say. They could have used some sort of drywall backup clip. Are you saying the sheet is loose?

 

I'm saying the at any given seam, one sheet is solid. The other can be pushed in with not too much effort again at the seam.

 

I'll see if I can't post a video

 

I don't see screws in either side. Is this a wall or ceiling? Are the seams vertical or horizontal?

 

It sounds like that sheet may have missed the stud. If so, it might be best to either take that sheet down and install extra framing as needed or if that isn't feasible, cut out enough to add framing and then reinstall the cut out piece of drywall.

 

It's like one side of each sheet is secured. And the other isn't. I'll take a picture from further away in a sec

 

Apparently, the first sheet installed was not cut down to the correct size so that the seams would land on a stud. If this be the case, removal and re-install would be in order.

 

You don't have to remove every board. Every second board would do the trick, just enough to install a nailer.

 

We do not know how far away from the seam the existing stud id located. Could be more than 3/4 in.

 

You can still just remove the affected boards [all or in part] and install framing. If the stud is too far from the end of the board you can always shim it out. There should be a row of nails/screws showing where the studs are.

 

You can see here in this picture 4 panels that are all secured on the right edge with screws.

All the left edges have no screws.

 

Take a thin putty knife and put it in the joint... then run it up and down. If you hear a click or feel it bump over something, they used backup clips, which may allow th e sheet to flex a little, but thats normal.

If there are no clips, then its a different story.

 

It doesn't matter where it is? Add studs as needed.
