What are your tips for cutting drywall

How and how to cut drywall and make holes in it

From this material you will learn how to cut drywall. Also, we're going to think about how to cut drywall and make rectangular and round holes in them. To do this, you need various tools and knowledge of the basic methods. In addition, we will show how materials can be used efficiently so that there is less waste and still achieve great results. We know from experience that while the cutting process is not very complicated, it takes patience to master it. An unsatisfactory result can be obtained due to inaccurate measurements, the use of incorrect materials and tools. This article provides tips on how to avoid common mistakes and how to get the most out of drywall.

Preparation and labeling

To cut drywall you will need:

Materials:

Tools

  • Stationery knife;
  • Tires tires;
  • Roulette.

Tips:

  • Only use the knife with a sharp blade.
  • if it is intended to fix drywall to both the ceiling and the walls, then at the beginning it is necessary to wrap the ceiling, and only then proceed to the walls;
  • If you need to cut drywall along a complex path, cut the length first, and then the width.

Remember that when editing and repairing drywall, it is very important to use as many whole boards as possible. This reduces the amount of material used, less work is required and the wrapping process is accelerated. Therefore, you need to carefully measure and examine the surface you are working with, and then make a plan for using the panels so that they have to be cut as little as possible.

If you need to install drywall over a large area, we recommend using 3.6 meter panels instead of 2.5 meter panels. This saves you time and material.

#1. Use quality tools to professionally cut drywall. If the leaves are large (120 cm wide), it is better to cut them and lean against the wall at a slight angle. And small leaves (up to 60 cm wide) can be cut on the ground. If this is your first time doing drywall, the best practice is to practice it on the floor. To begin with, you need to decide on which side drywall work will be carried out. To do this, make sure that the drywall sheet is facing you. An incision is made on this side.

If you don't know the best way to cut drywall then we can tell you from our experience that in most cases it is best to use a good stationery knife. But sometimes you have to use other tools. For example, a hacksaw for drywall construction is useful for cutting holes of various shapes.


The minimal kit of tools you will need for cutting drywall.

Clever advice. When doing drywall work on the wall, put down some wooden blocks. This makes the cutting process easier and protects your fingers from damage.

# 2. First you need to use a tape measure to determine the size of the cut panel. Be very careful with this or the oven may not fit and become either too small or too big. Also, make sure that the vertical edges are lined up in the center of the battens, otherwise the joints between the panels will not be stiff enough. Measure with a tape measure and mark the right place with a pencil, in our example we want to cut the board in half, so we make a mark in the middle.

Clever advice. It is very important to take accurate measurements, otherwise you will have to spend a lot of time and money correcting errors in the joints. Be especially careful when working alone.

# 3. Use a raiser to get the perfect straight cut. If you want professional results and need to do drywall work frequently and frequently, we recommend using a large T-square rather than using homemade or artisanal tools.

Move the tire lever on the drywall until the desired mark is reached.

We cut a sheet of drywall

#1. The plasterboard consists of two layers of paper that cover a thick layer of plaster on both sides. This combination results in a relatively strong building material that is also fireproof. In order to achieve a precise and high-quality cut, it is therefore sufficient to go over the plate with a sharp knife and then break it at this point. To make an incision, stroke the sheet of drywall several times with the knife. To get the right cut, you need to guide the knife safely, smoothly and precisely along the marked line. If you cut through the paper layer, be sure to hold the tread band firmly in one position, otherwise the cut may be uneven.

The same procedure must be followed if there is less chance that the drywall will not be on the floor, but rather be leaning against the wall. While holding down the trench with your foot, stroke the drywall several times with the knife from top to bottom. There is no need to cut through many times, all of which will just blunt the blade of the knife.


Sheet with cut paper base.

As you can see in the picture, the cut should be completely even. Otherwise, you will not be able to break the plate evenly. The goal is to cut through the paper completely and easily grasp the plaster.

# 2. Now you need to break the plate along the incision. If you've followed the previous steps correctly, the drywall should break along the cut. Holding the sheet with your feet, just fold it.

Of course, there are many ways to take a break. It is quite difficult to explain all of these processes in two sentences, but we assure you that in practice it is very simple. The most important thing is to make the right incision. How you break it doesn't matter.

But if you have trouble grabbing a large sheet of paper with your hands to bend it, press it in with your knee. If you're not sure if you can cut the plate well, practice on scrap sheets first.


Break drywall.

# 3. After breaking the sheet with an office knife, cut off the layer of paper on the back of the drywall. If you've broken through the drywall properly, you shouldn't have any problems cutting off a layer of paper from the back.


Cut off the cardboard layer from the outside.

# 4. Bring the divider plate to the installation site to see how accurate the cut is. When the cut plate has become a little stronger, remove any excess material with the rasp. Remember that working with a rasp creates a lot of dust. So try to make accurate markings.

How to make drywall holes

Next, we're going to talk about how to make a hole in drywall. Learning to drill holes in drywall is very important as new sockets, switches, and other equipment will often need to be installed. Also, round or rectangular holes need to be cut to repair damaged plasterboard. While cutting holes in drywall is quite easy, you will need to use certain tools and have some knowledge to do it professionally. For this reason, we advise you to work carefully and to carefully follow our step-by-step explanations before you begin.

To drill a hole in the drywall you will need the following:

Materials:

Tools 

  • Tires tires;
  • a pencil;
  • Tape measure and stationery knife;
  • drill;
  • Ring nozzle for a drill;
  • Jigsaw;
  • Hacksaw for drywall.

Tips:

  • Take accurate measurements to make rectangular holes.
  • When cutting holes, be careful not to damage pipes or electrical wires.
  • Wear a breathing mask to cut a hole in the drywall.

Cut a rectangular hole

#1. Determine the location on the drywall where you need to drill a hole. If it is going to build a socket into this hole, you will need to attach the socket from the socket in the required location and sketch its outline. To do this, use a tape measure to measure the distance from the left side of the panel to the left and right edges of the box. Also measure the distance between the bottom edge of the cooker and the extreme top and bottom points of the control box. With these dimensions, use a trowel to mark the location of the perforated box on the drywall.


Mark the sheet and determine the place for the hole.

# 2. Using a large diameter drill bit, drill 4 holes on the sides of the rectangle. As you can see in the picture, the holes need to be made inside the rectangle and as close as possible to the cutting lines.

Clever advice. You can drill holes in the corners of the rectangle, not on the sides. The holes need to be big enough for the jigsaw blade to fit into them.

# 3. Insert a jigsaw folder into each of the holes to cut a rectangular opening. Do this with great care and make sure that the file exactly matches the lines drawn.

Clever advice. Wear a breathing mask to avoid breathing dust. It is better to make the hole a little smaller than a large one, as the excess can always be removed with a rasp.

# 4. After cutting a hole in the drywall, you need to check its suitability. To do this, plug a box from the switch or socket into the hole provided to check that everything was done correctly.

Clever advice. You can cut holes in panels that have already been installed, but there are a few things to keep in mind. Before starting work, make sure that there are no cables, wires or other means of communication at this point.

How to make round holes in drywall

#1. First you need to determine how to cut a hole in drywall. There are various possibilities. For example, you can use a crown, a ballerina or a small hacksaw for this.

We recommend using a crown mounted in an electric drill chuck. It should be said that this is the fastest and most accurate method. It can be used to cut small and medium holes.

Before you start drilling, you need to make the appropriate mark. To do this, you need to identify and sketch the center of the future hole.

# 2. Select the crown of the desired size and fix it in the drill chuck. Now place the core drill in the center of the cut hole and start drilling. For a quality hole, we recommend cutting at medium speed and gently pressing the drill.

Clever advice. Do not press too hard on the drill so that the nozzle does not stick in the model. To get hole quality you need to be patient.


The hole is ready.

Method 1 Use a conventional knife to cut a round hole in the drywall. First you need to sketch the shape of the future hole, for this purpose you can attach a socket from a socket, switch or other round object to a sheet of drywall and sketch the contour of the future hole. Then the same outline should be noted on the back of the sheet. And the first and second circuits must match.

Then you need to completely cut through the cardboard layer with a knife. After cutting through the paper layer on both sides, lightly tap the plaster of paris with a hammer. The hole is ready. Now check to see if the control box is included.

Method 2 If you want to drill a hole in an already installed drywall, you will need to use a different method. Draw a circle on the drywall by dragging a pencil around the circuit breaker box or electrical outlet. Before cutting a hole in the drywall, make sure there are no pipes or electrical wires in this area. Also, make sure the box is in a convenient place.

Then use a plasterboard saw to cut a hole in the board. To make the hole smooth, break the drywall in one place and start sawing from there.
