by Staff
Someone slams the door open as they come running into your home and the doorknob punches a hole in the wall. You peer into the hole and discover that the walls are constructed of sheets of drywall. You decide you want to repair the damage yourself. Take this quiz before you head for the hardware store to make sure you know what to do.

Large holes in drywall:

  • require professional repair
  • can be repaired by a novice
  • require replacement of an entire sheet

Drywall joint compound is generally referred to as:

  • plaster
  • filler
  • mud

What is the process used to manufacture a typical sheet of drywall?

  • Gypsum compound is mixed with water forming a thick paste that is poured on paper and covered with paper.
  • Gypsum is sliced into massive sheets at the quarry and paper is glued on at a finishing plant.
  • Gypsum is sprayed on a paper backing in four layers to reach desired thickness.

What is the easiest way to fix a hole in your drywall?

  • You can fill the hole in a bit at a time with drywall mud.
  • Pick up a drywall repair kit that suits the location and size of the hole.
  • Stuff the hole with newspaper resting against the back side of the opposite wall and fill with drywall mud.

What should you do before you use a repair kit to fix a hole in drywall?

  • You need to use a razor knife to bevel the edges around the hole first.
  • You need to sand a one-inch wide area around the hole with coarse sandpaper first.
  • You need to remove any loose paper or gypsum around the edges of the damaged area first.

Is drywall mud or spackle suitable for repairing smaller holes in drywall?

  • No, there is a special compound specifically designed for smaller repairs on drywall.
  • Why not, it is the same compound that was used to fill cracks in the original installation.
  • Yes, it is identical to the special repair compounds that cost much more.

What is a first step to repairing a small hole if you choose to work without a repair kit?

  • Smear compound on cardboard with a string in the middle, put through hole and pull it against the wall back.
  • A small hole that is no bigger than a doorknob can be fixed by filling the hole with repair compound.
  • Prepare a can lid that is at least 1.5 inches bigger in diameter than the hole you want to repair.

How do you hold the can lid in place while you fill the hole?

  • Put compound on the lid before you put it in the hole, pull it against the wall and let the compound dry.
  • Thread wire through holes in the lid, put it in the wall and hold the wires while you fill the hole.
  • Thread wire through holes in the lid, put it in the wall and wrap the wires around a stick placed against the outer wall.

What do you do now that your can lid is fastened tightly against the inner wall?

  • Fill the hole and the slots that you cut so that compound is level and feathered on the surrounding wall.
  • Put just enough of the repair compound on the can lid to hold it in place and when it dries remove the wire.
  • Fill the hole and the slots you cut so the compound is slightly lower than the surrounding wall.

What is the last step in your repair after a final coat of compound dries?

  • Sand the patch lightly before you prime and paint it.
  • Paint your patch to match the existing wall.
  • Prime the patch first before you paint it.

  • You will need a professional to repair a large area of drywall properly.
  • A repair of this scope will require you to purchase a proper but expensive repair kit.

What will you need to repair a large hole or a large damaged area of drywall?

  • You will need a piece of chicken wire slightly larger than the repair area.
  • You will need a roll of self-sticking fiberglass drywall tape.

How do you make the repair piece fit snugly into a large damaged opening?

  • Cut the scrap so it is slightly smaller than the hole you are repairing.
  • Cut a scrap so it is slightly larger than the hole, trace the scrap on the wall and cut the wall just inside the line.
  • Cut a piece out of the wall much larger than the hole so you have a stud on each side to attach the scrap.

What is the next step after you create the opening for the scrap you cut?

  • Put mud around the edges of the opening, slip the repair piece in place and hold it until the mud dries.
  • Put a board 6 inches longer than the hole inside the opening and attach it to wall back with flathead screws.
  • Fit the repair piece into the opening, hold it in place with fiberglass drywall tape and cover tape with mud.
