How to Repair Large Holes in Drywall

Introduction:
Repairing a large damaged hole in the drywall requires some effort, as it distorts the overall shape of the wall and the room.
So in this project we will learn how to repair large holes step by step.
 

Step 1 : Materials and Tools

Materials:
  • Drywall panel OR Scrap piece of plasterboard (drywall).
  • Joint compound-premixed plaster filler.
Tools:
  • Pencil.
  • Yardstick.
  • Utility knife.
  • Serrated knife.
  • 150 grit sandpaper on a sanding block.
  • Power screwdriver .
  • Screws.
  • Mesh drywall tape - plaster tape.
  • A bendy putty knife.
  • brushes to cover the finished repair.

Step 2 : Equip the Repair Area

First you need to make a hole around your damaged hole.Where we will draw a square around the damaged hole using a pencil and Yardstick.
It’ll make it possible for you to patch it with a piece of the drywall panel you bought Or a drywall of excess of previous works.
When your hole isn’t quite that big, you would do things a little differently about this case. 
then cut out a piece of the drywall panel that was the same size. You can either measure your square hole and then measure out what you need to cut from the drywall piece.

 


Step 3 : Cut Out Damaged Area

After we have identified the damaged area, we come to discharge this damaged area from old drywall.
we cut through the drywall using the serrated knife.
After it’s cut, you can pull out the old drywall chunks and Clean the area well.
You’ll have a rough edge around your cut, so sand it well with 150 grit sandpaper and wipe off dust with a paper towel or Cleaning Brush .
 

Step 4 : Attach New Piece

You’ll need to grab a piece of wood and attach it inside the hole to the back of the drywall using 1-1/4″ drywall screws.
Then, Attach the new drywall to its place, and install it in the backwoods using 1-1/4″ drywall screws also.
So we popped our drywall patch into the hole, we cut and screwed it into our studs on either side. And we did three screws on the left, three on the right.


Step 5 : Tape and Joint Compound

Then we used the mesh drywall tape to tape around the four edges around the patch. Where it helps the joint compound stick in the gaps.

Then, Get some joint compound on your putty knife and press it over your patch, starting in the middle and feathering it away.
 Let this dry 24 hours ,then come back and sand it and clean well.
And do a second coat. You’ll basically repeat the steps from before.
After each time of coat, sand it and clean. So you get a level surface and not coarse.
 

Step 6 : Paint and Finish

You are there a new smooth area with no flaws.We will paint to calibrate the wall color and hide the repaired area.
Prepare the color of the unified wall, here our color is white.
Then paint this area with a brush or a small paint roller.
 
Leave work dry and enjoy.
