How to Fix
Dented Drywall

WHAT YOU NEED FOR THE PROJECT:

Tools:

Materials:

  • Drywall Compound
  • Fiberglass mesh
  • Fine-grit Sandpaper

How to Fix a Dent in Drywall

  • Before you begin, clean the dent well using a utility knife. Remove damaged paper layer and any residue
  • Prepare the surrounding surface by removing paint with a sanding block and 120-grit sandpaper. This allows the compound to bond properly.
  • Clean away dust from sanding with dry cloth
  • Make a small amount of drywall compound in a bucket by pouring a small amount of water in before adding the powder
  • Let soak momentarily before mixing thoroughly
  • Repeat adding more powder to bucket until you reach the proper consistency. If the mud does not slip off the putty knife and is not lumpy, it is ready for use.

CPO Tips: To avoid lumpy mud, don't pour in drywall compound powder at once. Use your putty knife to add powder incrementally.

Step 4:

  • Using your putty knife, fill in dent with a thin first coat of drywall compound
  • To reduce painting, avoid spreading compound over a larger surface than necessary
  • Level the surface by scraping putty knife over the patch
  • If done correctly, the dented area should now look like Step 6 below. Let set for a few minutes before continuing

CPO Tips: Apply mud quickly before it dries out. Wash tools thoroughly after mixing mud.

Step 6:

Important: If your dent is shallow and the gypsum layer is undamaged, you may skip the following section on installing fiberglass mesh. If your dent is deep, you will need to follow these instructions.

  • Measure the size of the dent
  • Using a utility knife, cut a small strip of fiberglass to cover the dent
  • Making sure it is sticky side down, center your mesh over the dent and provide gentle pressure with your putty knife
  • Embed mesh tape and eliminate any air pockets that may form. Go over the mesh several times to smooth out
  • Let set for approximately 10 minutes

Step 7:

Step 8:

  • Spread a second coat of mud over the first
  • Make as smooth as possible in comparison to the rest of the wall
  • Let dry thoroughly
  • Using a sanding block, sand smooth with medium-grit and fine-grit sandpaper
  • If not satisfied with result, clean dust and apply another thin layer of drywall compound

CPO Tips: If surface is still rough after second coat, let dry overnight and apply another layer.
