View Full Version : Drywall Thickness Question..

In the process of remodeling a bathroom that has an exterior wall, I had to move some plumbing. This necessitated cutting away a piece of drywall 28" high by 48" wide. I moved my plumbing and while fitting my new 1/2" drywall, I noticed the old drywall nearest the exterior wall is slightly thicker than the new drywall.

However, the old drywall that is farthest from the exterior wall is flush with the new piece.

I also noticed when cutting out the hole I didn't cut across any drywall seam, meaning that the old drywall at that location was installed horizontally. Is this normal?

The house was built in 1982.

The question is, will I ever be able to mud and feather such that it will be difficult to tell the uneven thickness when looking at it side-on, or is this a lost cause and I should just do the best I can and live with it?

Thats normall with patching. It never fits exactly right. If it is really bad like 1/4" or more it will be best to shim it flush first. With some time and a lot of mud you will get it flush. Yes it is normall to hang drywall horizontally. It is not normal to hang it vertically.

Did you put a tapered edge next to one side of the hole? That could make it shy. Fill it flush with some setting mud then tape it and finish it as you would the rest.

While removing some ceramic wall tiles, the other side of the wall was punctured. I need to patch about 4 inches of drywall. I have a few peices of scrap drywall used for a den wall. May I use this for the patch?

Welcome to theforums wcamet

I always prefer to use scrap for repairs - I hate to cut a little piece out of a new sheet :D Just be sure that you have the same thickness as you don't want the repair to jut out past the wall :wall:

Yes, that's it. That edge is not as thick.

Also, for some odd reason I always had it in my head that drywall is usually mounted vertically from floor to ceiling. Anyway, tomorrow's the big day (Saturday) that I do the mud thing and prep for painting.

This has been an interesting experience. :cheshire:
