Drywall repair - Large patch, or remove entire sheet?
DougLanglois

I have a four foot wide floor to ceiling interior wall that needs a very large patch. The hole is about two feet wide and from the floor to less than six inches below the drywall seam.

To the left of the hole is an inside corner, to the right an outside corner.

I'm not sure which is the easier and cleaner course of action, keeping in mind that I am not skilled with drywall -

1. Patch it as is, and deal with the resulting butt joints.

2. Pull the entire 4x4 lower sheet of drywall out, leaving me finishing half an inside corner, half an outside corner, and retaping the taper joint.

3. Pull out the lower and upper drywall sheets and start from scratch on that wall.

I would do a total replacement patch, let me explain.

If you fully remove the drywall from corner to corner, you then have to retape the inside corner, transferring your repair to the adjacent wall. If you remove the outside corner, you then have to patch the mating corner because you've disturbed the corner bead. As you probably already know, trying to blend in a patch to existing work is tough for even us experienced guys, for a novice it will be extremely hard.

So what do you do? If it were me, and I've been in situations just like this many many times, I would cut the damaged wall 2"-3" from the corners and ceiling. I've got a 4' level that is a little over 2" wide, I just use that as the marking guide, virtually anything will work, whether you measure and mark with a chalk line or scribe with a stick. What this does is gives you a flat butt joint for your new drywall so that you do not have to disturb or retape any corners, less work, easier work. The one tip I'll give you here is that if at all possible, do away with the beveled edges of the drywall, basically, if you can keep the total area under 42" wide by 96" tall, trying to mate a beveled edge to a full thickness edge is a pain in the patootie. Don't worry if your patch joints don't line up on studs, you can add blocking along the sides, either attached to the studs or screwed to the remaining drywall edges to give support and attachment points for your patch.

All that is left is to flat tape everything, taking your taping all the way into, but not around, the corners. When you've got your taping finished to the level you are happy with, all you do is mask off your corners and spray your texture. Better yet, have a helper hold a spray shield for you, that way you can compare your texture job with the existing and work it until you've got a close match.

Two coats of primer, two coats of paint and you're done! Time for a beer and to sit back to admire your work. :cool:

Your other option would be to only patch what needs patching, then float the whole wall smooth, retexture, repaint, though it doesn't sound like this option is really going to save you any time or hassles.

There is one more option:

- Hire a handyman with drywall skills, grab a chair and watch him do the repair/replacement. Remember what he does and next time you need drywall work, use your knowledge from watching him. Win win.

Patch unless the whole area is cracked or weakened for the reasons already given. Anyone can do a flat patch pretty well but corners are for pros. Tons of youtube vids to help you figure out which patching method will work best for your situation. One bit of advice rarely seen is that when your patch is finished, plan to prime then paint but look for flaws as you do that and fix them before putting the final finish paint on. You'll see a lot more flaws with paint on than you can see with just the bare patchwork. Just keep sanding and skimming till you're happy or till you can't do any better. So what if it takes you 9 skim coats of mud? You're not a pro and nobody is going to know that when you're done. Patience pays off here like nothing else.

Thank you all.

Kind of late to the thread but I've patched up a few holes this big it's fairly easy. A lot less hassle! Just curious, were you able to get this done yourself?
