Preparing and applying the markup

To cut the drywall, you will need the following:


  • drywall sheet.


  • stationery knife;
  • racing;
  • roulette.


  • use a knife with a sharp blade only;
  • if you intend to fix the drywall both on the ceiling and on the walls , then at the beginning it is necessary to sheathe the ceiling, and only then proceed to the walls;
  • if you need to cut drywall along a complex trajectory, then first cut the length and then the width.

Remember that in the process of working and fixing drywall it is very important to use as many whole plates as possible. So you reduce the cost of materials, work will be less, and the process of covering will go faster. Therefore, you need to carefully measure and study the surface with which you work, and then draw up such a plan for using plates so that they should be cut as little as possible.

If you need to attach drywall to a larger area, we recommend using 3.6-meter boards instead of 2.5 meters. So you will save time and material.

# 1. To professionally cut drywall, use quality tools. If the sheets are large (120 cm wide), then it is better to cut them, leaning against the wall at a slight angle. And small sheets (up to 60 cm wide) can be cut on the floor. If you are cutting a drywall for the first time, then it is better to practice doing it on the floor. In the beginning, you need to decide which side to cut the drywall. To do this, make sure that the sheet of drywall is facing towards you. It is on this side that the incision will be made.

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

The minimum set of tools you will need when cutting drywall.

Smart advice. If you cut drywall by placing it on a wall, then lay down a few wooden bars. This will ease the cutting process and save your fingers from damage.

# 2. To begin with, it is necessary to determine the size of the cut plate using a tape measure. Do this very carefully, otherwise the stove may simply not fit - it will turn out to be either too small or too big. Also make sure that the vertical edges are aligned to the center of the batten, otherwise the joints of the plates will not be rigid enough. Measure with a tape measure and make a mark in the right place with a pencil. In our example, we want to cut the slab in half, so make a mark in the middle.

We cut a drywall sheet

# 1. The gypsum plasterboard consists of two layers of paper, which on both sides cover a thick layer of plaster. This combination creates a relatively durable building material, which is also fire resistant. Therefore, in order to get an accurate and high-quality cut, it is enough to walk around the plate with a sharp knife and then break it in this place. To make a cut, slide the knife on the drywall sheet from top to bottom several times. To make the right cut, you need to lead with a knife confidently, without jerks and exactly along the marked line.Cutting the paper layer, you need to firmly hold the tire in one position, otherwise the cut may be uneven.

The same procedure should be performed if you rarely drywall is not leaning on the floor, but leaning against the wall. Holding the crosspiece below with your foot, slide the knife over the drywall several times from top to bottom. No need to cut through many times, so you just dull the blade of the knife.

As seen in the picture, the cut should be completely flat. Otherwise, you will not be able to break the plate evenly. The goal is to completely cut through the paper layer and lightly grab the plaster.

# 2. Now we need to break the slab along the notch. If you have completed the previous steps correctly, then the drywall should break along the cut. Holding the sheet with your feet, just fold it.

But if you find it difficult to grab a large sheet with your hands to bend it, then press it down with your knee. If you are not sure that you can cut the slab well, then first practice on sheets of waste.

How to make holes in drywall

Next, we'll tell you how to make a hole in drywall. It is very important to learn how to make holes in drywall, as this is often needed to install new outlets, switches, and other devices. In addition, it is necessary to cut round or rectangular holes in order to carry out repairs of damaged plasterboard sections. Although it is quite simple to cut holes in drywall, it is necessary to use certain tools and some skills in order to do this professionally. Therefore, we advise you to work with caution and to follow our step-by-step explanation precisely before taking up work.

To make a hole in drywall, you need the following:


  • Sheet of Drywall


  • rack;
  • pencil;
  • tape and stationery knife;
  • drill;
  • ring nozzle for drill;
  • jigsaw;
  • hacksaw for drywall.


  • make accurate measurements to make rectangular holes;
  • be careful not to damage the pipes by cutting the holes or electrical wires;
  • to cut a hole in the drywall, wear a respiratory mask.

Cut a rectangular hole

# 1. Determine the place on the drywall where you need to make a hole. If it is supposed to install an outlet in this hole, then in the necessary place you need to attach a box from the outlet and draw its outline. To do this, use a tape measure to measure the distance from the left side of the plate to the left and right edges of the box. Also measure the distance from the bottom edge of the plate to the extreme upper and lower points of the electrical box. Given these dimensions, with the aid of a rail, mark the location of the hole for the box on the plasterboard.

Method 1. You can cut a round hole in a drywall with a regular knife. At the beginning you need to outline the shape of the future hole. To do this, you can attach a box from a socket, a switch or any other round object to the sheet of drywall and outline the contour of the future hole. Then the same outline should be noted on the back of the sheet. Both the first and second contours must match.
