Small holes can be filled directly, but larger patches must be supported with some kind of backing, such as plywood. To repair holes left by nails or screws, dimple the hole slightly with the handle of a utility knife or taping knife and fill it with spackle or joint compound.
All drywall repairs require three coats of joint compound, just as in new installations. Outline the damaged area using a framing square. Cutting four right angles makes it easier to measure and cut the patch.
Use a drywall saw to cut along the outline. Wearing protective gear is important when working with drywall compounds and tools. When someone punches a hole or misaims the hammer when nailing up the walls, it is important not to panic. This is the most common type of drywall damage. You can either use mesh tape or cut out the hole and patch it with sheets of drywall, whichever you find easiest. Damaged holes can be categorized into small, medium, and large holes.
Holes between a couple of centimeters to an inch do not require patches or mesh tape. Use joint compound to cover the hole and provide a smooth surface for painting.
You can also cut a small drywall square and fill it into the hole. A joint compound can be painted on top before it dries out to make the surface smooth again.
If the hole is larger than an inch, then cut it out. You will need a new piece of drywall material that is twice the size of the hole. Be sure to measure and cut properly; otherwise, you will have unnecessary gaps in the repair work. Cut a square around the damaged area and saw off any protruding corners or edges. Clean the sawdust off using a brush and apply joint compound on the area where you will place the patch.
Place drywall tape over the top and firmly press to smooth out any bubbles or bumps. After it has dried, use sandpaper to make it even with the wall surface. Holes larger than 10 to 12 inches need to be repaired using mesh tape. Cut out the damaged area and clean out all of the sawdust off. If the hole has jagged edges, use sandpaper to smooth them down before applying joint compound.
Cut a piece of mesh tape with an inch more on each side than what is needed for filling in the patch. Apply joint compound on the mesh tape and smooth it out with a taping knife. Place the mesh tape over the hole and make any adjustments if needed. Dust off any excess joint compound from your work area before it dries up. Call in a professional if you run out of materials or do not have enough time to complete this project.
This happens when the drywall studs have been secured too tightly into the wall. The nails will be slightly raised from the surface and require a little attention to make them completely flush with the wall.
Use a flathead screwdriver to press down on the nail head, making sure it is pushed in. Leave it there for at least twenty minutes or until you see that the nail head has sunk further. Punching drywall nails causes damage that is much more difficult to repair. Once you remove the screwdriver, use a hammer to firmly tap on the top of the nail until it is pressed completely flush with the wall.
It usually takes more force than usual, but be careful not to hit too hard. If you mistakenly damaged the corners of your passage or doorway or want to cover up any damaged areas of your drywall, you can use a corner bead. It is a series of metal profiles used on interior corners for durability and easy installation.
When the pop-outs happen in the corner, take out all the broken pieces and clean off any dust or debris. Apply joint compound on the entire area to become smooth before applying filler. Once the compound dries out, sand it down with sandpaper to make it even with the rest of the wall.
Cut a piece of corner bead at least 4 inches long and attach it to the corner using drywall screws. Secure it into place using your screwdriver while aligning the profile to the corner wall. Drill two holes along each side of the corner and one in the middle. Patching textured wall requires a bit of extra work to finish. After patching, take four parts of compound and 1 part of water, mix it well and dip a stiff brush into the mixture.
Sprinkle the mixture on the wall with gloved fingers and fix the texture using the brush. Once it is properly set, use sandpaper to smooth out any jagged edges. Textured walls are not for rough treatment and sometimes require more attention than regular drywall. Then cut along the lines with a drywall saw. Make sure there is no wiring or plumbing behind the drywall surface before cutting by looking through the hole with a flashlight. Cut two pieces of lumber or plywood a few inches longer than the long sides of the hole if it's a rectangle.
Place one piece into the hole, parallel to one of the long sides, so the strip is centered over the drywall edge half is behind the drywall and half is exposed.
Secure the strip with drywall screws driven through the drywall and into the strip. Keep the screws about 1 inch from the drywall edge, and space them about 6 inches apart. Repeat the same process to install the other backing strip along the opposite edge of the hole. If the hole is more than 10 inches wide, use the method above to frame in the entire opening with lumber strips. Cut a piece of drywall to fit the hole.
Position the patch over the hole and secure it to the backing strips with screws. Keep the screws about 1 inch from the edges of the patch and space them 6 inches apart. Cut strips to length of drywall joint tape using a utility knife.
Cover each seam with a strip of joint tape. Overlap the tape strips at the corners. Make sure the tape lies flat, with no wrinkles or bulges.
Cover the drywall tape with a thin layer of drywall joint compound, using a 6-inch drywall knife. You should be able to see the mesh through the compound. Let the compound dry. Then scrape the surface with the knife to remove any burrs or clumps.
Apply another thin layer of compound, extending it beyond the edges of the first layer. Use the knife to feather the edges of the wet compound over the surrounding drywall so it gradually tapers to nothing.
