If there’s a hole in the wall or ceiling in your home, you’re probably frustrated because you don’t know how to fill it up without leaving a noticeable mark. But don’t worry! Treating a hole beautifully is also simple if you know how, have the right tools and materials. Often you can also use these methods to repair holes in old-fashioned plastered walls or ceilings.
Steps
Fill holes caused by nailing

Pull the nail out with your hands or with pliers – don’t use a hammer. Turn the nail so it loosens, then pull it straight out. Thus, in the wall there will be only a small hole that is easy to repair.
- Do not use a hammer to pry the nail out unless absolutely necessary, as the hammer’s mount will leave large marks in the wall. If using a hammer to remove nails, place a piece of wood or a book between the hammer and the surface of the wall. [1] X Research Source
Tip: If there are screws in the wall, you should unscrew them, not pull them out. If you pull out a nail, you can leave a big hole in the wall. Use a multi-purpose knife or paring knife to scrape the paint in the cross-groove on the screw head.

Use a putty knife to fill the hole with putty. Fill the hole with putty into a small mound that you will flatten once it dries. [2] X Research Source
- Use latex putty for the best surface finish for the nail hole. You can buy putty at building materials stores or online.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/2c/Repair-Hpes-in-Drywall-Step-3-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-3-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/2c/Repair-Hpes-in-Drywall-Step-3- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-3-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait for the putty to dry. The time it takes for the putty to dry depends on the brand of the product. [3] X Research Sources
- Hot, humid areas usually take longer to dry.

Repaint the hole with wall paint. It may not be exactly the same color as the wall paint, so you should only paint on the spot you just filled in so that the color difference is not easily noticeable. Use a 2.5cm paintbrush to paint small spots. [5] X Research Sources
- You can take paint scraps to a building materials store to find the right paint color, but it’s often hard to find a perfect match.
Handling protruding nails and screws on the wall
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/54/Repair-Hpes-in-Drywall-Step-6-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-6-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/54/Repair-Hpes-in-Drywall-Step-6- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-6-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
If there is a slightly raised nail or screw on the wall, you can either drive it in with a 3cm nail or screw in the screw so that it sinks just below the surface of the wall and put putty on top. [6] X Research Sources
- If the screw head has a cross groove, you can use a paring knife or paring knife to scrape the paint in the groove, and then use a screwdriver or battery drill to screw the screw into the wall.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8c/Repair-Hpes-in-Drywall-Step-7-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-7-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8c/Repair-Hpes-in-Drywall-Step-7- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-7-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
To prevent the wall from crumbling or cracking when you are working with the protruding nail, you can drill a drywall screw above and below the nail to secure it. Old wall mortar is very easy to crack. Tighten the screw in slowly until the screw head retracts just below the surface of the wall. [7] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/bf/Repair-Hpes-in-Drywall-Step-8-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-8-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/bf/Repair-Hpes-in-Drywall-Step-8- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-8-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a hammer and nails to drive the nails into the wall. Square studs are also useful for this.
- Nail or screw into the wall about 2mm deep, creating a small hole for the putty. [8] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/2c/Repair-Hpes-in-Drywall-Step-9-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-9-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/2c/Repair-Hpes-in-Drywall-Step-9- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-9-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Use a sanding sponge to smooth the surface to be filled. Use drywall sanding sponge to sand the drywall surface and putty to create a smooth paintable surface. Scrub with a gentle circular motion to smooth the surface of the wall. [10] X Research Source
- Take care to rub the edges of the putty carefully so that it is not exposed when painting. Wipe the surface with a wet sponge also ich.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/af/Repair-Hpes-in-Drywall-Step-12-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-12-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/af/Repair-Hpes-in-Drywall-Step-12- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-12-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Paint a coat of primer over the patch. Use a paint brush to prime with wide, even strokes. Apply a sufficient amount of primer to cover the patch and the junction between the putty and the wall. [11] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/35/Repair-Hpes-in-Drywall-Step-13-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-13-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/35/Repair-Hpes-in-Drywall-Step-13- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-13-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Paint the patch with a topcoat that matches the surrounding surface. To make sure the patch is not exposed, you need to use paint that matches the paint on the wall. Use a clean paint brush to apply enough paint to cover the primer. Wait for the paint to dry and apply another coat if necessary. [12] X Research Source
- Take the scraps of the wall to the store as a sample to buy paint if you no longer have such paint at home.
Treat small holes in walls or ceilings painted with putty
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1f/Repair-Hpes-in-Drywall-Step-14-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-14-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1f/Repair-Hpes-in-Drywall-Step-14- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-14-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a hard trowel to scrape the surface around the hole, removing the rough surface. These are pieces of putty that are sprayed onto a wall to create a grainy texture. [13] X Research Source
- Scrape off any flaking paint around the edge of the hole.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b7/Repair-Hpes-in-Drywall-Step-15-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-15-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b7/Repair-Hpes-in-Drywall-Step-15- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-15-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a hammer to create a slope on the edge of the hole. Tap around the perforation in one direction to create an even gradient across the edge of the perforation. This way, the edge of the hole will be slightly steeper and easier to put putty on. [14] X Research Source
- If it is an old-fashioned plastered wall or ceiling (not plaster), you should be careful not to knock hard or it will crack.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/20/Repair-Hpes-in-Drywall-Step-16-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-16-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/20/Repair-Hpes-in-Drywall-Step-16- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-16-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a spatula to put putty into the hole. Fill the hole with putty so that it rises slightly above the surface of the wall. You will scrape or sand when the putty is dry. [15] X Research Source
- Use latex putty for best results.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d5/Repair-Hpes-in-Drywall-Step-17-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-17-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d5/Repair-Hpes-in-Drywall-Step-17- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-17-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use the edge of the putty knife to apply the putty. Rub back and forth several times in different directions on the putty surface until smooth. This step will push the putty in all directions so that the hole is completely and evenly filled. [16] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d5/Repair-Hpes-in-Drywall-Step-18-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-18-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d5/Repair-Hpes-in-Drywall-Step-18- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-18-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Once the putty is dry, you will use a hard plaster knife to scrape it flat with the wall or ceiling surface. [18] X Research Sources
- Be careful not to chip or crack the putty as you scrape with the edge of the trowel.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/6b/Repair-Hpes-in-Drywall-Step-20-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-20-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/6b/Repair-Hpes-in-Drywall-Step-20- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-20-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Spray a layer of rough paint over the putty.
- Adjust the nozzle to fit the wall or ceiling. In order for the patch to harmonize with the surrounding surface, you should test spray paint on a piece of cardboard. Hold the paint bottle 15 cm away from the wall and spray a sufficient amount of paint to evenly spread the edge of the putty so that it blends with the drywall. Wait for the paint to dry according to the instructions on the product packaging. [19] X Research Source

Paint over the hole. Use the same paint color as the surface around the hole just filled. Use a 10 cm paint roller to create a surface similar to the surrounding surface that was also painted with the roller. [20] X Research Source
- Bring pieces of wall paint to match the paint color if you need to buy paint.
Patching large holes in drywall or plaster walls
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c0/Repair-Hpes-in-Drywall-Step-22-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-22-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c0/Repair-Hpes-in-Drywall-Step-22- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-22-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
If the hole is 13 cm x 13 cm, you will use a 15 cm x 15 cm wall patch. For smaller holes, you can use a 10 cm x 10 cm patch.
- Use putty to attach the wall patch (see instructions on the package).
- Wait for the putty to dry, then apply a thin layer of putty over the wall patch. Use a 15 cm plaster knife and a 40 cm trowel (to hold the putty).
- Apply a second coat after the first coat has dried.
- Apply two coats of paint. Use a 10 cm paint roller to match the paint texture of the surrounding surface.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/88/Repair-Hpes-in-Drywall-Step-23-Version-5.jpg/v4-728px-Repair-Hpes- in-Drywall-Step-23-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/88/Repair-Hpes-in-Drywall-Step-23- Version-5.jpg/v4-728px-Repair-Hpes-in-Drywall-Step-23-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a wall patch to patch a large hole.
- Cut the hole into a square rectangle to fit the rectangular drywall patch. Use a 40cm x 60cm square frame to draw the edges of the hole.
- Measure the edges of the hole. [21] X Research Source

Cut a piece of plasterboard equal to the size just measured. [22] X Research Source
- Use plasterboard of the same thickness as the wall, if available. Gypsum boards usually come in 3 different thicknesses. You can use a drywall saw blade (wallboard saw blade) for sawing. If you don’t have drywall of the right thickness, you can use thinner material and apply several layers of cardboard underneath the patch to level it with the wall surface.
- Buy the smallest size plasterboard, usually 60 cm x 60 cm.
- The edges of the plasterboard should be neatly cut and smooth. If necessary, you can use a multi-purpose knife to sharpen. [23] X Research Sources

Remove pieces of drywall and trim around the edges of the hole. Take one edge and bend it inwards and up again to break away from the wall. Continue in this manner until all pieces of plaster that may remain are removed. [25] X Research Sources
- Do not tug on the plaster pieces to avoid damaging the wall.
- The hole you just cut out in the drywall should be square and smooth for you to attach the plaster patch to.
