How To Repair a Crack

There is no specific reason to get cracks in your walls and ceilings. Mostly, they are caused due to settling of the house, contraction and expansion. In fact, every house at some point in time will develop cracks. So, here are some ways that will go a long way in helping you fix cracks quickly without burning a hole in your pocket.

Hairline Cracks

Hairline cracks in the wall are the simplest to fix. You would just need a putty knife, utility knife, joint compound, mesh tape, sandpaper, sponge and paint. Follow the below mentioned steps and your wall will soon be as good as new.


  1. Clean the area: Get rid of any loose spackle, plaster, grit etc.
  2. Cut trench: Use the utility knife to cut a trench bigger than the crack.
  3. Use mesh tape: Apply mesh tape around the crack, covering it completely.
  4. Fast-drying compound: Make use of flexible compounds that are water resistant and fast-drying. This is especially true for the kitchen and bathroom that are always moist.
  5. Fill smoothly: Use the putty knife to liberally apply the compound in the crack. Spread and fill compound carefully while feathering it.
  6. Let it dry: Let it dry overnight. Once dried, gently sandpaper the area to get rid of excess compound. Check for blemishes and grooves using a damp sponge. If the crack comes back, it is time to call for professional help.
  7. Apply three coats: Keep applying three coats of the compound and letting each coat dry will cover the crack completely.
  8. Paint the patch: Paint the entire wall or just the patch in the colour to match the rest of the wall.

For Larger Cracks

Don’t panic if the cracks in the wall are big. Use the following steps to repair the crack yourself.

  1. Gather materials: To repair a bigger crack, you would need a taping knife, plastic mud pan, drywall tape or fibreglass, drywall compound, sanding block and fine-grit sandpaper.
  2. Clean the crack: Scrape off the edges of crack to get rid of dust and debris.
  3. Apply light coat of compound on the crack: Put compound on the mud pan to easily load it on to the taping knife. Now apply a light coat on the crack using the knife. The coat should not be thick, but it can be wet.
  4. Layer tape over compound: Immediately after applying the compound, embed it with the tape. Use a wider knife to scrape away excess compound. Scrape in a smooth and slow motion.
  5. Apply another layer of compound: Apply another layer of compound ensuring the edges are feathered. Let it stand overnight to dry and then apply the third and final coat. Blending the compound edges is very important.
  6. Sandpaper to smooth the patch: Use a fine grit sandpaper to smooth the patch. Apply primer over it and you are done!
