How to Repair
Holes in Drywall

WHAT YOU NEED FOR THE PROJECT:

Materials:

  • Drywall Compound
  • Fiberglass mesh
  • Fine-grit Sandpaper
  • Drywall Sheet
  • Drywall Screws
  • Appropriate-Sized (1×2) Lumber

Prepping the Hole


  • Square holes are much easier to repair. Mark a square area around the hole for cutting with a pencil. Use a straight edge to make sure the corners are right angles
  • Before cutting use a stud finder to check if there are studs, pipes, or electric cables
  • Cut marked square area with a drywall saw or reciprocating saw. Make sure to be accurate and not to tear edges
  • Important: Before patching, make sure to clean any loose paper / plaster from around the edges of your cut

CPO Tips:

If your drywall hole is bigger than 4”, you should install more than one backing support.


Step 1:


Step 2:


Installing Backing Support


  • Using measuring tape, measure width & height of hole
  • Use the reciprocating saw to cut the 1×2 lumber approximately 2" taller than the hole height
  • Place the backing support centered inside the hole
  • While holding the support, use your drill to drive screws through the wall into your support
  • Do not overtighten screws, as it could damage your drywall
  • Once completed, remove the middle screw you were using as a support

CPO Tips:

Drill a screw into the support for easy installation and support while drilling screws through the wall into the support.

Cutting / Installing the Drywall Patch


  • Important: You MUST use a drywall sheet with the same thickness as your wall, or it will not be level with the rest of the wall
  • Mark the outline of the patch and gently cut with Drywall saw, do not damage
  • Put the patch in place and make sure no gaps are larger the 1/4". If larger gaps are present, cut a new piece
  • Secure the patch to your backing support with several screws
  • With the utility knife, cut enough pieces of fiberglass mesh to cover the entire work area
  • Place the mesh adhesive side done, making sure the strips overlap slightly
  • Put a small amount of water in a bucket and gradually add drywall compound powder to avoid lumpy compound
  • Let powder absorb some water, then mix thoroughly, until it is a thick, smooth consistency

CPO Tips:

To avoid cracking later, make sure your fiberglass mesh strips overlap slightly and cover your entire work area, edges included.

Applying Drywall Compound and Finishing Up


  • Using your putty knife, apply first coat of drywall compound. Make as even / smooth as possible
  • Mark the outline of the patch and gently cut with Drywall saw, do not damage
  • Let the first coat sit and dry before applying a second coat
  • Apply a second coat with a large putty knife. Make as flawless as possible
  • Give drywall compound at least 8 hours to dry
  • After 8+ hours, use fine grit sand paper (120 is good) to smooth the patch
  • Work in a circular motion, paying attention to the transition between the patch and the rest of the wall

CPO Tips:

Apply another thin coat using a cross (+) pattern if you cannot make the wall even.
