Drywall cracks are some of the most annoying things that can happen to your home and they look really awful and often end up absolutely demolishing the whole demeanor of your home. Therefore, in this guide, we will be teaching you how to repair Drywall cracks in your home without any technician or specialist help whatsoever. All you will be needing are a couple of supplies and some equipment that can be found at your local departmental store.

We strongly recommend that you ensure that there aren’t any exposed electrical wires or water pipes behind the wall so that you aren’t in any immediate danger. Also, make sure to wear safety goggles and all the necessary safety equipment to prevent any harm from befalling you.

In this guide, we will be taking you through the step-by-step process involved in fixing drywall cracks in your home, and keep in mind that these can be recreated to fix the ceiling as well given that it is made out of the same material.

How To Repair Drywall Cracks:

  1. Take the Crack tape out of its box and place it over the crack in the wall, measure over the crack, the length of the tape that you will require. Cut the tape just 1 inch short of the length of the crack and place it aside.
  2. After cutting the tape, put the plaster repair on the Flat Plaster tray and using the Scrapper, spread it along the crack and make sure that you spread it over a larger area than the crack so that no air pockets can be formed.
  3. Once the crack has been covered completely, place the same Crack tape that we cut before and it should now, stick to the wall. Make sure to place this tape in such a way that it covers the crack along the length of the wall and that the crack has been completely covered.
  4. Take some more Plaster Repair and using the Flat Plaster Tray and Scrapper, spread it out evenly on the tape and rub the tray over it to flatten it in such a way that it now covers the whole length of the crack, make sure not to use too much plaster just enough to cover the tape.
  5. Rub the Scraper flatly over the surface to flatten and spread it even more and let it sit once you feel like the first coat is done.
  6. Wait for at least 3 or 4 hours after the first coat has been done so that the wall has had some time to dry.
  7. Now that this first coat has dried, it is time for us to apply the second coat. In the second coat, take the Plaster Repair and Skim and put some on the Flat Plaster Tray, pick this up with the scrapper and spread it out evenly along the length and width of the tape, and make sure that no air pockets are formed by flatting it out evenly by pressing the scrapper against the wall.
  8. After completing this coat, wait for another 4 hours and let it sit to dry out. After drying, we will now be applying the third and last coat and while doing this, we will also be skimming the entire wall to ensure structural integrity and to make sure that the crack doesn’t come back after some time.
  9. Take some Plaster Repair on the Flat Plaster Tray and using the scrapper, apply it to the end of the wall. Flatten this out using the Flat Plaster Tray and spread it out evenly across the wall by pressing it flatly against the wall.
  10. Using this method, make sure to coat the entire wall or an entire section of the wall that you deem appropriate.
  11. Let this sit for at least 12 hours.
  12. Now put on the Double Strapped mask on your face to prevent the sanding debris from going into your lungs.
  13. After putting on the mask, rub the sandpaper alongside the wall and make sure to cover the entire wall. Flatten out the wall and you can feel it with your hand to confirm if it has been properly evened out.
  14. The Drywall crack should now be completely repaired and you can easily use concealer over the wall and paint it, tile it, or put wallpaper over it without any worries of the crack coming back. However, keep in mind that the crack might come back if there is a structural integrity issue or water leakage or seepage.

Repairing Drywall Cracks on Ceilings:

Repairing such cracks on ceilings is pretty much the same as the method listed above although they involve some really small adjustments. For instance, we have highlighted some below.

  1. Just make sure to support your ceiling from the bottom with an elongated plack so that it doesn’t fall down or crack more, you can do so by placing a flat piece of wood on the top of your ceiling and then support it with a big wooden plaque that comes all the way down to your floor and it sits beneath the piece of wood in such a way that it doesn’t let it fall and keeps it in place over the crack. Make sure to have this piece of wood there before you actually start the repairing process from the top of the ceiling.
  2. If you have a hole in the ceiling or a crack that goes through all the way to the top of the ceiling, it will require you to repair this first. For instance, you can place a hardwood plaque on the top side of the ceiling from where it has been cracked and screw it into the ceiling to ensure that the crack is filled.
  3. After filling the crack, you can simply use the method that we have highlighted above to put the crack tape over the crack and apply 3 coats of skim from time to time to ensure that this crack is completely repaired.
  4. After repairing this, you can imitate the paint on your ceiling to make sure that it matches the one that was there before.
