I would appreciate any tips anyone has on how to repair drywall tape that has popped loose on inside corner joints. My house is 8 years old and the tape has come loose in a few spots and I need to fix these before painting. Some areas are only 1-2 inches long but unsightly. Thanks for the help.

 

Hello Larry3427,

What you will need to do is cut out the loose tape with a razor knife, cut it all the way back to where it is still adhered good, you will need a mud pan and a 6" tapeing knife, get a blob of the joint compound on one side of the knife and apply to one side of the angle, smoothly and evenly, leave no bubbles or missed spots, do the same for the other side of the angle, going a little past where the existing tape is still adhered, take a piece of the tape that will not go past the mud you applied but slightly longer than the spot to be patched, crease it and stick it into place, you may have to hold a corner of the tape down with a finger so it doesn't move and wipe down both sides of the angle, getting the tape as flat against the wall/ceiling and into the angle as possible without overworking it. Then apply a thin layer overtop ONE side of the taped angle in the same manner, feathering out the edges, let dry and and do the other side. After it all dries completely, sand smooth.
