Wall Repair Steps
How to fix a hole in your wall.
Supplies
You will need a drill with a Philips head bit, Compound, Compound tape, Putty knife, drywall sanding block, 1 1/2 drywall screws, Tape measure, pencil, Utility knife, New drywall piece and 1x3 wood strip. Not included (SAW)
Cut the Hole to a Square
First use your utility knife to cut a square hole in the drywall, Cutting out all broken pieces.
Bevel All Edges of the Square
Using your utility knife cut at a 45 degree angle at all sides of the drywall so the compound can sit nicely.
Cut and Screw in the Wood Strips
This is to back your drywall patch piece. Cut these with an extra two inches above and below your hole. Install these vertically parallel with half of it visible and half not. Screw into place with 2-3 screws sunk below flush level but not breaking the paper.
Cut Your New Drywall Piece to Size and Screw Into Wood
Cut your new drywall piece from extra drywall to size of hole with the utility knife and screw this into the wood.
Tape Over the Edges
Now with your tape lay it over the visible edges to join the pieces together.
First Coat of Compound
This should use the most compound and apply this vertically then wait for it to dry. Cover your tape, screws and hole.
Second Coat
This should be less than the last coat but layer this horizontally and wait for it to dry.
Third Coat
After your second coat is dried install this coat vertically but with less mud then before to make a smoother finish making sure no tape is visible.
Sanding
Once the third coat is dry, sand the mud to make it smooth and flush with the wall.
Paint
After you have sanded paint your wall to its color and you have successfully patched a hole in a wall!
