Old inside corner tape failing
In my bathroom renovation I managed to save the top half (4ft) from demolition or so I thought. On closer inspectio, it appears that the old paint has cracked and the tape has split at the cracks. I probably already know the answer to this. Do I need to sand off all this old corner tape and start over with new tape? Or can I get away with mudding or painting over this area?

What has likely happened is that when the original D/W was hung, they fastened both sides of the corner up close. This seems proper, at first, but it is a poor practice because when walls move a little in relationship to each other, (and they will) the solidly fastened down inside corners have no flex and the tape usually cracks... along with the paint on top of the tape.

You can either sand the old tape, or tape over it... really doesn't matter... it will keep on happening as long as the walls find a reason to move some.

I am seeing more and more of this in newer homes. I've seen a couple where the paint starts riplling at the corners and lots of cracks. When I peel the paint back I can tell that there is only one layer of mud laid (the first layer) and that's it. No wonder they have houses popping up overnight:furious:

It would be best to tear out the old tape and retape the corners....
