Transcript:How to Patch a Hole in the Wall
Hi, Im JJ Burkart for About.com. Im going to show you how to patch a large opening in drywall.
Supplies for Patching a Hole in the Wall
You will need:
- 1 ¼ drywall
- ½ inch drywall
- wallboard taping knives
- a sponge
- quick-set drywall compound
- and 120 grit sandpaper
Instructions for Patching a Hole in the Wall
In this case I cut and removed a large piece of the drywall in order to access the area behind the wall. If you are using a new piece of drywall, cut your opening with right angles. Then cut your patch so that you have a one-eight inch gap all the way around so the drwyall doesnt bust out at the seams.
Additional Instructions for Patching a Hole in the Wall
You will need something to anchor the drywall patch to. If you can, use the studs. In this case I am using a firring strip so I can anchor the patch.
Place your patch and place screws every 4 to 6 inches all the way around
Take a razor blade and remove the fuzz from the edges. Cut in a V shape.
Sand the edges until it is smooth.
If you have time, it is better to use a ready-mix compound and apply one layer each day over several days. In this case I need to get the job done quickly, so I am using a quick-set compound. Once the powder is mixed with water, I have a short period of time before the compounds sets up or starts to harden. You want the compound to be the consistency of mayonnaise. Peanut butter is too thick which means you add more water.
Spreading Compound to Patch a Hole in the Wall
This step is commonly referred to as mudding. Scoop some compound, or mud, onto your knife and scrape it across the wall surface until its smooth.
Apply a second coat of mud to the area you are going to tape. Without tape, the drywall will eventually crack along the seam. Apply the tape to the mud in a straight line and scrape the knife along the length of the tape holding it at a 70 degree angle and applying a good deal of pressure.
You will need a flexible wallboard taping knife for angles such as this. Apply a layer of mud to the corner using the corner tool. Fold the tape in half so it fits into the corner. Use the corner tool to apply the tape. Apply another layer of mud to cover the tape. Try to keep all the layers as thin as possible so that you can avoid unnecessary sanding or having a raised hump in your wall.
Once the mud has completely dried, sand off the top layer so that it matches the adjoining drwyall thickness. In other words, so you cant see or feel a hump. Use a moist sponge to smooth the edges of the mud and to remove mud from areas where you may have inadvertently spread or dripped some compound. Clean your tools in a bucket of water. Do not wash drywall mud down the drain.
