Trace The Outline Of The Hole You Want To Cut

This is the most important step of the process. Make sure you have everything ready to go before marking your outline.

If you’re using a new drywall piece (preferable) or your original piece, have it laid out on top of the hole so that it’s facing straight down and flush with the wall. 

Once you’ve got it set up how you want it, place some painters tape along all four edges of your molding paper. This will help protect any areas that could be damaged during cutting into your old wallboard if taken off later in this project.

Now take a pencil and start drawing around where you want to cut out so that there are no gaps between what remains attached to your walls and what will come off as well; plan ahead so that nothing gets lost during this process!

Use A Stud Finder To Locate The Supports

You can use your stud finder to locate the supports. A stud finder uses a magnet to locate the studs in the wall, which are usually made of wood (and therefore magnetic). 

The better quality models will also detect metal objects, so you’ll know that there’s something in that wall before you put it through.

Once you’ve located your supports, take measurements from those points on both sides of where you want to cut out a hole and transfer them over to your new drywall sheet. 

You should have two separate measurements for width and height when using standard 8 foot sheets of drywall.

Table: Tips for Using a Stud Finder to Locate Wall Supports

1.Calibrate the stud finder according to the manufacturer’s instructions.
2.Move the stud finder in a slow, steady motion along the wall, starting from the floor and moving up.
3.Look for the signal indicating the presence of a stud, which is usually a beep or light.
4.Mark the location of the stud with a pencil or tape measure.
5.Repeat the process to locate the other studs, which are typically 16 to 24 inches apart.
6.Keep in mind that some studs may be oriented vertically, while others are oriented horizontally.
7.Use caution when hanging heavy items on the wall, and always use appropriate hardware and anchors.

Drill Holes Inside Each Corner

To ensure that you drill the corners properly, set your bit in the center of each corner and drill a hole through the drywall. 

In order to protect your hands as well as keep the drywall from flying around, place a piece of masking tape over your fingers on each hand.

Once that’s done, place the tip of your bit into one of these holes and mark where it meets up with another wall or stud (use a level if needed). Make sure to mark both sides so you know where everything needs to go.

Now drill another hole out at an angle in between those two marks until it goes all the way through both walls or studs..

When it comes to plumbing issues, some problems require a little extra DIY effort. Our pro guide on fixing plumbing issues covers common plumbing problems, preventative measures, and step-by-step instructions on how to fix them yourself.

Insert A Drywall Saw And Make The Hole

If you’re going to cut a hole in drywall, you’ll need to use a drywall saw.

These are the steps to follow:

Take a good grip on the saw. Hold it with both hands and push down on it firmly, using Make sure that your blade is sharp. Sharper blades make cleaner cuts and don’t require as much force to do so.

Use new blades as often as possible, since they’ll be more efficient at cutting than old ones would be.

When using a saw for this purpose, don’t apply too much pressure—you’re not trying to cut through steel here! Instead of pushing down hard on the tool or letting it stall out when it gets stuck, just keep going slowly until you’ve made your way entirely through one side of the wallboard sheet into your intended target area behind where you want your new hole placed. 

Cut A Larger Hole Around The Damaged Area

To begin, you’ll need to cut a larger hole around the damaged area. The new opening should be at least 1/2 inch larger than the damaged area on all sides.

Next, use a drywall saw to cut out the damaged section of drywall from ceiling to floor. If you’re working with metal studs (as opposed to wood), drill holes in each corner so you can attach new metal strapping where appropriate.

Drywall repair can be a daunting task, but it doesn’t have to be. Check out our guide on how to cover up drywall repair for tips on how to keep your walls looking smooth and seamless.

Determine How Many Pieces You Will Need To Cut

Determine how many pieces you will need to cut. If you have a small hole and don’t want to patch it with drywall tape or mesh, then use a few smaller pieces instead of one large piece.

Table: Steps to Determine How Many Pieces You Need to Cut for a DIY Project

1.Measure the length and width of the area you will be covering, such as a wall, floor, or countertop.
2.Calculate the total square footage of the area by multiplying the length by the width.
3.Determine the size of the tiles or pieces you will be using for your project, such as 12-inch square tiles or 6-inch strips.
4.Divide the total square footage of the area by the total square footage of one tile or piece to determine how many pieces you will need.
5.Round the resulting number up to the nearest whole number to ensure that you have enough pieces to cover the entire area.
6.Add an extra 10% to your total number of pieces to account for any waste or cuts that may be necessary.
7.Make a plan for how to cut the pieces to fit around corners, edges, or other obstacles.
8.Use a tile cutter, circular saw, or other cutting tool to cut the pieces to the appropriate size and shape for your project.

Measure, Mark And Cut All Pieces Of Drywall You’ll Need

Measure and mark the drywall pieces you’ll need. To cut a hole in drywall, you’ll need to measure it first. 

Use a tape measure to measure the length and width of the area where you’ve decided to make your hole. Mark these measurements on all four sides of your piece of drywall (or use painter’s tape).

Cut out each piece with a drywall saw or utility knife. Once you have your measurements marked, carefully cut through each side of your piece using either a drywall saw or utility knife if necessary, depending on how large your hole is and what type of tool makes cutting through wood easier for you personally (a handsaw works well for small holes but can be difficult to handle if they’re big).

Even the most minor wall repair can be challenging when it comes to matching texture. Luckily, our guide on how to match texture on wall repair breaks down the process, including tips on how to achieve the perfect texture match.

Fit The First Piece Into Place And Screw It In

The first piece of drywall will be the easiest to install because you can use it as a guide. This is also one of the most important steps, so make sure that you do it right!

The first thing you want to do is check that your drywall pieces are straight by using a level. If they aren’t, use a screwdriver or drill to tighten them together and make sure they’re aligned properly before continuing. 

Once your drywall is straight, find where the screw holes are on both sides of the hole in your wall and use a pencil (or anything else) to mark where they should go. 

Now take out any loose pieces from inside this box and drill through those two points with either a drill bit or awl depending on what kind of tool you have available for this step (if possible). The reason why we need these holes is so that when we put our screws through them later down below

Fit, Level And Screw In All Subsequent Pieces Of Drywall

Now that you have the first piece of drywall in place, it’s time to get started on the rest.

Level and screw in all subsequent pieces of drywall. To do this, level the drywall on both sides (use a level to make sure it is straight), use a tape measure to make sure it is the right size and mark where you need to drill holes for your screws with a pencil or something similar (you can see how this will look in our video).

 Then, using your power drill, drill carefully into each marked hole so that each screw goes through both pieces of drywall at once. Once they’re all in place, screw them tight!

Apply Drywall Tape Over All Seams

After you’ve finished taping the seams, use a drywall knife to apply tape over all seams. This will ensure that no holes are left exposed, which can lead to leaks and water damage.

Be sure to cover all seams completely—it’s important for a smooth finish.

Let The Compound Dry For About 4 Hours

If you want to get the best results, we recommend that you wait about 4 hours before sanding. This will allow for the compound to dry and help ensure a smooth surface on your patch job.

Once it’s dry, apply another coat of drywall compound over the hole (and any other areas where there are cracks). Wait for this layer to dry overnight before sanding it down.

Sand With 120-Grit Sandpaper Lightly Coated With Water

Sand the drywall compound with 120-grit sandpaper and a damp cloth. Cover the sandpaper lightly with water, then gently rub it over the patch. 

The goal here is to smooth out any bumps or ridges left from applying the compound, not to sand them away completely. If you press too hard, you may scratch up your drywall or dent it permanently which could lead to new problems down the road (like cracks).

Apply Separate Coats To Cover All Seams Completely

After spreading compound onto any area that needs to be repaired, use a putty knife or trowel to spread it evenly over the surface. To ensure that your repairs are smooth and neat, make sure you let each coat dry for at least 4 hours before applying another layer of compound. 

For example, if you’re repairing two holes in your drywall in a single day, let one coat of compound dry for four hours before beginning work on the second hole (this will give you plenty of time to apply compound and sand down areas where necessary).

Let Compound Dry Overnight Between Each Coat

Let the compound dry overnight between each coat. Drywall compound is inert and will not harm you, but breathing it in can irritate your lungs, so wear a dust mask while sanding.


If you follow the steps outlined above, you’ll be able to repair your drywall. The key is to understand how much work it takes and how long things need to dry before moving forward. 

If you want professional help, call a contractor or ask someone at your local hardware store for advice on how best to tackle this project.
