How To Do Drywall Repair Like the Pros - page 2
Drywall Repair for Dummies
Adding drywall to our hole
Take your tape measure again and measure the hole from top to bottom on the left, and top to bottom on the right, write that number(s) down. Now measure from left to right on the top, and left to right on the bottom, write that number(s) down. If you cut your hole out nice and square you should have two numbers, example being 24" height and 14" width. If your hole is a little off then you may have four different numbers, example being 24" height (left) 24 1/4" height (right) and 14" width (top) 14 3/8" width (bottom).
Move over to your piece of sheetrock and measure your numbers on the drywall, then use your chalk-box to snap lines. Use a combination of your keyhole saw and razor knife to cut the drywall and take your piece over to the hole. Once you set the piece in the hole you may have to do a little trimming to get it to fit. Take your screws and set them around 6" apart all the way around the perimeter and on any center studs if applicable.
Let the taping begin
If you have any gaps in-between your new drywall and existing drywall you need to back fill them with mud before you start taping.
Once your repair is back filled and the mud is dry take your fiber mesh tape and apply it to your seams.
Add your first coat of mud with a 10" or 12" metal knife. If you go the paper tape method, spread your mud on the seams about 6" wide. Cut the tape to fit with no gaps and place it on the seams. Then wipe the tape down, if you press too hard you will squeeze all of the mud out and you will get a "bubble" effect, if you don't press hard enough you will have a mound which will prove hard to float out. Find the happy medium, if you get the "bubble" effect no big deal, just add more mud under the tape and wipe down again. That covers your first coat also known as the tape coat.
For the second coat you take your 10" or 12" knife and get some mud on it. Set one end of the knife on the center of the tape and apply the mud evenly. Now put some more mud on your knife and do the other side of the seam. In other words, if you use a 10" knife you should have a 20" wide strip of mud on one seam. Do this around the perimeter of the repair. After the mud has been applied take your knife and wipe down one side first, then the other side, then the middle. You may have to play with it a little bit to get the desired effect. Also remember that sometimes playing with it will make it worse, it’s okay to walk away and fix it on the next coat.
Finally, the third coat. Take your knife and instead of running two swipes of mud, make it three. For example, if your using a 10" knife you should now have a 30" swipe of mud centered on your seams around the whole repair (doesn't have to be exact). Again, wipe down one side, then the other side, then the middle again. Your repair should look pretty good by now. By good I mean flat and smooth.
Note: not every repair requires the seams to be floated out that far. You will have to run your hand over the surface to determine this.
If your repair has waves or scratch marks or anything of the sort just add another coat of mud. Be sure not to pile too much mud on at anytime.
Once the repair is looking pretty good, take your sanding sponge and do some sanding. After sanding is done do any touch-ups as necessary.
Beginners may need to sand in-between each coat.
