What is the biggest patch in order to use drywall sheet for tape ?

Hello I would like to know what would be the biggest section of drywall that can be replaced without the use of drywall tape but using the drywall sheet paper for tape ?

I don't know that I'd go with a width much wider than 4" but it can go a good bit longer. It really needs to be determined by what/where it's being patched. How tight the patch piece fills the hole also makes a difference on how stout the repair will be.

OK how big a patch are you trying to do?
What drywall "sheetpaper".
You mean tape?

You can make a patch without using tape by removing some of the gypsum and leaving the perimeter with an inch or two of just paper. Around here rockers call it a "hot patch." I've never seen it used for anything much larger than 4". It's good for patching openings for moved outlets, switches etc.

Are we still discussing this? http://www.doityourself.com/forum/pa...ml#post2554228

We try to keep similar threads together so we don't have to jump around like ground hogs looking for a better view.

Hello everyone the piece of drywall that needs to be cut is about 5 1/2" wide x 5 1/2" height or rounded to about 6" x 6". Can I cut out the replacement piece to about 7" x 7" ?

You need at least 1" overlap with the excess face paper to secure it to the wall. That would put the patch piece size at 8x8. The tighter the remaining drywall on the back side fits the hole the stronger the patch will be.

I would still try to put some structure behind that patch so you could screw it in place.

Not familiar with the apparent other thread you have on this so I apologize if I'm being redundant.

Great thanks I think I'll follow what both markr and stickshift have suggested. Since the repair patch will be bigger than 7" x 7" I use a wood support in the back.

question for marksr:

A one inch overlap on a 7"x7" opening would give you a 9"x9" patch - not 8x8. Am I correct? using 8x8 would leave a 1/2" overlap on each side.

I based my 8x8 off of that statement. Somewhere along the line the size of the hole changed It's always best to have a 1" or more overlap on all sides when using that method for patching.

I just want to ask one more question. I cut out a piece of damaged drywall which shows the inner side seems to be crumbling see photo ? I plan to use some wood backing to screw the new patch drywall to the wood backing. Will this be OK or do I need to cut the drywall opening bigger until the drywall cut out all the way around is a solid base (not crumbling as seen in the picture) all the way around ?

Your cut needs to be fairly uniform and smooth. What did you use to cut this with, a hatchet? Use a razor knife and follow lines drawn to guide your cut.

hello chandler yes i used a utility knife. Should I make the cut bigger until there is no signs of crumbling until the drywall opening all the way around should be not crumbling but rather uniform and smooth ? Yes I did use a pencil and a ruler to make straight lines all around the damaged area so that I could follow with the utility knife.

I prefer to use a jab saw [keyhole] when cutting out drywall that is already hung. IMO it's quicker/easier than making a multiple knife cuts.
