It’s tough to get rid of the spot naturally.

Here you will know how to fix a wall or ceiling crack.

You need to follow three main steps to fix the wall or ceiling. First, you have to clean and tape the ceiling crack. After that, put 5-minute mud to cover the damage. Lastly, complete the repair in only three steps. In these three steps, there are a few steps you need to follow to fix it.

Above I mentioned three steps above, but these three steps individually have many more. You will know in detail if you scroll and read the whole article.

Let’s get started!

How to Fix a Crack in the Ceiling

Here I will talk about the main three steps in detail so that it can be easier for you to understand and begin the process.

Step 1: How to Clean and Tape a Ceiling Crack

1. Place a layer of plastic beneath the crack because you’ll be removing debris, adding mud, and creating a mess. But while fixing your ceiling crack, it’s a good idea to lay down a wide plastic bag beforehand.

  • This way, when you’re through mending the crack. You can toss away the sheet of plastic and avoid having to clean your flooring.
  • You should also remove any upholstered or fabric-covered furnishings from the room, as it will be challenging to scrub off the paint and dirt.

2. Construct an A-frame ladder. An A-frame will stabilize you when you stand on it to approach your ceiling. Before climbing the ladder, ensure all four legs are solid and level on the floor. Also, if you can, avoid making rapid movements.

  • You may use a fold-out part across from the top of your ladder. It’s for storing your tape, mud, and other repair tools.
  • A-frame platforms should be found at your local hardware or household store. A 6- or 8-foot (1.8-2.4 m) ladder will come in handy.

3. Use a drywall knife to scrape away any loose debris. Place a 6-inch (15-cm) drywall knife at a 15-degree angle against the ceiling near the crack. Slide it beneath any loose, detached drywall paper pieces near the break. Slice them off with the knife, careful not to harm the drywall beneath.

  • Drywall knives will be accessible at any hardware, paint, or home improvement store. Several sizes will be available, but the 6-inch (15-cm) is usually the most efficient.

4. Mesh drywall tape should be applied immediately over the crack. Because this tape is sticky, it will adhere securely to your ceiling. Long strands of tape should be used to cover the whole damage. Depending on the depth of the crack, you might well be able to cover it entirely. You need a single strip of tape for that.

  • Place the tape over the crack and push it against the ceiling. Apply only one layer of tape.
  • Stretch the tape out with a rolling pin or can. This is the same tape you use to join the gaps when installing drywall.
  • It may be purchased from a local hardware store or a home-supply store. If the business has a selection of tapes, get the sticky version.

Step 2: 5-Minute Mud for Crack Repair

1. Combine the 5-minute mud pack with water. Shake 1 pound (0.45 kg) of dry mud into a big plastic container. Pour in lukewarm water from the kitchen faucet. Using your putty knife, stir the mixture into the 5-minute mud. You have to do it while placing the bottle over your kitchen sink.

Continue to add water and stir till the mud has the thickness of mayonnaise. 5-minute mud, however, will settle more securely than joint compound. Also, it will strengthen the structural strength of ceiling drywall. You may also use silicone caulk to seal the ceiling crack.

  • You may also use mud that dries faster, such as 20-minute mud. Applying dirt with a prolonged drying period allows you to complete the repair in less time.
  • It is unlikely to fall on you if you don’t make the mud too runny. But you will need extra time first to get the hang of patching a ceiling.
  • Spritz the ceiling with a spray bottle to assist the mud clinging to the existing plaster. Dirt doesn’t adhere to dust, grease, mold, or surfaces that are too flat or loose.

2. Apply a coat of mud to the break in your ceiling. Ensure that the mesh tape is fully covered in mud. Create a single, smooth coating of dirt with the broad side of your putty knife.

  • If possible, put the mud in a straight line parallel to the fissure. Working fast is essential since the mud will dry in 5 minutes.
  • Wait 30 minutes after applying the initial coat for the mud to dry completely.
  • If the mud coating appears uneven, smooth it with a moist sponge before it hardens.

3. Texture the dirt if your ceiling is textured. Texturing the mud will aid in integrating with the rest of the ceiling. The type of ceiling determines the best approach to adding texture to the mud.

  • If your ceiling has a spiral texture, reproduce the design in the mud using a delicate paintbrush.

You will need so many paintbrushes. Have a look at my recommended products:

Wooster BrushThe Wooster brush features gold polyester with chisel trim for all latex or oil paints. The ferrule is made of brass-plated steel with a black solid plastic grip.
Purdy Paint BrushNatural hardwood handle with angular trim—a ferrule with a round edge made of stainless steel, superior cutting capabilities, and simple cleanup. Purdy’s clearcut glide brush is suitable for use with any paint.

You will find the reviews if you are confused about buying the paintbrushes.

  • To imitate a knock-down texture on your ceiling, first push a stiff. Then a moist piece of paper into the dirt.
  • Use a popping ceiling repair spray to cover the mud if your ceiling has a popping texture.

4. After the initial layer of mud has dried, sand it. Sand any rough places in the dirt with a sandpaper sponge in a back-and-forth movement. You will do it if you want to seal the toilet with wax. Polishing the dirt between coats will help the finished product seem more refined and sophisticated.

5. Make another batch of 5-minute mud. The second layer should be thinner than the first. So, add additional water from the kitchen faucet to the same quantity of sand.

  • The thinner coat will cover flaws or bumps in the first mud application. This batch should be mixed until it has the texture of cream cheese.
  • Push any pockets of dried sand off the borders of the plastic, combining the container. And with the frames and edge of your putty knife.

6. Put on the second layer of mud. Apply the second coat in the same manner as the first. Coat the mesh fabric thoroughly with mud. This coat should help hide the grid structure on the paper. So it’s not noticeable after you’ve scrubbed and repainted the ceiling.

  • As with the previous mud application, let it dry for 30 minutes. It should dry in 5 minutes, but giving it a little more time is preferable. To ensure it’s scorched and ready for painting.

Step 3: Completing the Repair

1. Using a polishing sponge, smooth the mud coats. Scrub the mud-covered surface with the sanding sponge. You’ll need to file the rough sections after the fracture has been structurally mended.

  • Washback and forth so that the dried mud fills. The previously cracked region is smooth and flush with the rest of the ceiling.
  • Polishing sponges are available at most hardware stores. If they come in different grits, use a fine-grit polishing sponge.
  • Depending on how much-hardened muck you sand off, it may produce a big mess. Ensure that most weight lands on the plastic sheet you’ve set down.
  • If you currently have fabric-covered items in the room. Try covering them with drop cloths to prevent irreversible damage.
  • You may want to match a mainly level surface. Make the last layer of mud more watery than the previous two coats and spread it. You can use a 14 or 18-inch trowel on the ceiling. The longer shovel will fill up low places and flatten the surface.

2. Choose a paint color that complements your ceiling. The repaired and polished piece of the ceiling needs to be repainted. It will resemble the remainder of the ceiling if you have any remaining paint from when you repainted your ceiling. So, you can utilize it to cover up the mended crack.

  • If you don’t have leftover paint, you’ll need to go to a paint store. Also, you can go to a home improvement store to obtain a matching coat. Paint may also be stocked and mixed at larger hardware stores.
  • Collect multiple paint-color samples and contrast them. Check with your ceiling to determine the closest match.

3. Paint the sanded-down area of the ceiling. Put around 12 cups of paint into a steel painter’s tray once you’ve obtained it.

  • Slide your roller brush through the paint. Upwards and downwards until the whole surface of the brush is covered.
  • Then, going from one end of the mended crack to the other. Apply a coat of paint to the ceiling using the brush.
  • Your ceiling should have a consistent hue and pattern. Once you’ve completed painting and the paint has dried.
