Everyone who works or plans to start working with the GC, faces the question how to cut drywall. You can perform this simple and at the same time a difficult operation in several ways.
The most popular - cutting of plasterboard sheet in a straight line. For this, the GLC is placed on a flat surface in a horizontal position. After that, with the help of a pencil and the rules, the smooth line is noted, according to the inclination. Then the sheet is turned over and is abolished along the cut line on the other side. To understand how to cut plasterboard correctly, consider all situations and methods of cutting in more detail.
To begin with, we will define which tool we need for this operation. How to cut drywall:
- Normal or special knife cutter for gypsum-changing blades
- Roulette
- Rule, rule or cord for marking
- Electrol Rasp with shallow pail (for cutting sheet of uneven line)
After cutting the plasterboard sheet, it will be necessary to process its edges, so for this we will use:
- Champagne
- Robbing plans
How to cut drywall in a straight line
Cut the drywall sheet in a straight line is not so difficult. To do this, put the GLC on a flat horizontal surface (on the floor or on the table), we make the necessary measurements using a simple pencil. It should be noted that it is not recommended to use a marker or handle for marking, as traces remain from them, it is practically impossible to sharpen.
After measurements, we leave the label from below and on top of the sheet. We apply the rule or level to these labels and blacks.
Now proceed to the sharpening. To do this, we will need a sharp knife with an adjustable blade long. At the same time, the blade should perform from the knife handle for a length that does not exceed the thickness of the plasterboard. We make an incision for the left line. In order for the line to turn out to be more even, it is necessary to walk 2-3 times on the cut by the knife, so we will deepen it.
If the sheet was lying on the table, then it is necessary to move it so that the cut part performs beyond the edges. Now you need to take the edges of the leaf and a sharp movement gently dump along the line of the outbreak, then we make another embryo with a knife on the reverse side.
If the cutting of the plasterboard sheet was performed on the floor, then after the end it is necessary to put it on the edge, and with light tapping on the whole side to make a dummy and then healing the cardboard with a knife.
On a note! You should not use a circular saw for cutting plasterboard. Using this tool can be compared with the clogging of nails by stone. Such a saw creates a huge amount of dust that adversely affects the mechanical parts of the instrument and on your lungs.
How to cut the plasterboard in the form of the letter G
Usually a plasterboard sheet is cut in the form of a letter G to cover the doorway. The operation is not complicated, but for its execution we will need a hacksaw, which we cut down a short part. The long part is cut according to the scheme described above the knife.
How to cut drywall for non-smooth line
A more complex process of cutting drywall on a curved line, for example, when we need to cut an oval or a circle. For this work, we will need an additional tool - electrolovka with shallow sawn. You can try to cut the sheet with a knife, but the guarantees that the incision will be smooth and neat very little.
During the cutting of drywall, a lot of dust is formed by an electrolybiz, so it is necessary to take care of personal protective equipment (safety glasses, respirator).
How to cut the plasterboard mounted on the wall
If you need to decide with a plasterboard sheet, the window slope or the angle of the wall and at the same time make it so that its edge perfectly coincides with the walls of the wall, then the inclination of the GLC is performed "on the spot", that is, the sheet has already been cut. As a rule, for this, a slice of drywall is a little larger than necessary and the unnecessary parts are cut after that.
To properly perform this operation, the plasterboard sheet must be securely fixed on the frame. An incision is made along the other side of the sheet that adjacent to the trimmed surface. We spend several times in an outlined line, slightly pressed on an unnecessary piece. After that, the leaf on the reverse side is dominated. In order to cut a sheet in the form of the letter G on the page already attached to the frame, we cut the horizontal line with a knife, after which the vertical line is dredging with a knife.
How to cut a hole in the drywall under the socket or light bulb
Such holes are cut into the drywall sheet usually after it is installed. . How to cut drywall in this case?
For this operation, we will need a crown for drywall (circular saw) or hacksaw on plasterboard. In building stores, you can purchase a set of crowns for HC of different diameter. These devices are installed on a screwdriver or drill.
Cut the hole with hacksaw more difficult, and the edges of the hole will not be so smooth.
Treatment of plasterboard edges after cutting
After cutting the edge of the leaf of plasterboard, as a rule, not very smooth and smooth. To make them more accurate and at the same time to prepare the joints of the installed sheets in the shtlock, it is necessary to remove the champions with a special plane. This can be done with a conventional knife. Typically, the chamfer is removed on 2/3 sheet thicknesses at an angle of 45 degrees.
Cut the drywall correctly - the task is not complicated, and to consolidate the material, we advise a great video clip.

Industrial release started in 1917 in the UK. However, invented a new building material in a resident of the United States. Rate Ugasta Sekket was issued back in 1894. The American brought 10 paper sheets to the powder with plaster powder.
It turned out a plate width of 5 millimeters. The modern width is at least 1.5 millimeters more and then, subject to the reinforcement of the core of fiberglass.
Standard sheets rise by 10-13 millimeters. The question arises how to cut such a crowd, because in work it is often necessary to customize under the framework. We describe several ways to divide the plates.
Cut the plasterboard with electric jigsaw
Lobzik - a tool with a reciprocating movement of the peel. Simply put, we are talking about a miniature variety of electric saws. In working with plasterboard it allows you to:
Figure cuts
Holes inside sheet
Maximum exact edges without jar and contour drops
Cut the plasterboard with an electric bison
Electrolzik drawing plasterboardby a predetermined contour. Since gypsum dust will be eased from under the blade, make the backbone of the black marker. It is visible under whiskers.
Place the sheets from the back. However, drywall is only the basis of structures covered after tile, wallpaper, plaster. Therefore, the markup side is not fundamental. Let's start work:
- We put a gypsum sheet on stools or bricks, leaving space under the cut line free. Also, the cutting line should not have voltage. His rupture strength worsen the quality of the cut. The basis of the plasterboard is based due to the flexibility of the material. Without support, the sheet can break under pressure in unforeseen places.
- We install the jigscription at the start of the loop line or bring plasterboard to the tool tripod, because it happens not only autonomous, but also stationary. Also, in a number of jigsaws there is a laser sight. It helps to "go" exactly on the markup. In the case of operation in the twilight, the backlight will help. She also is not on all jigsaws.
- It remains to turn on the jigsaw and behave smoothly on the markup.
- In the final to heat the edges with emery paper or branch, file.
Disagree how to cut drywall jigsaw It is only with the tool. The most promotional models are from the 1100th rubles. If the spent are unreasonable or at hand there are no purchased jigsaw, curly cuts do ...
Cut the drywall knovke
Hoven is also a type of saw, but already manual. There is a tool, usually several hundred rubles. Woven hacksaws are different. Needed smooth with small teeth. This is a metal hacksaw.
Cut the drywall knovke
When working with plasterboard, it gives the most even cut. The subtlety of the saw blade allows it to be easily bent inside the sheet, passing exactly by curvilinear markup. Start the process:
- Having placing plasterboard and making a drill or a knife in its corners of the hole for the entrance of the handbreak.
- By inserting the hacksaw to the slot and dying to the opposite point.
- Having treated the edge of the cut by replacement means.
Which side cuts drywallit does not have a hacksaw value, but in what place is important. When drinking a sheet from the edge, the tool gives a flat, neat line, although it has to spend a solid time. The through holes on the canvas of drywall knife gives uneven. It is better to use the jigsaw here.
Cut the plasterboard by mounting knife
In the mounting knob shift blades. There are canvas for cutting different materials, adjusts the protrusion of the metal part beyond the knob. There are same stationery models, but for working with plasterboard they are low-power.
Cut the plasterboard can be even a stationery knife
There is a mounting knife from several hundred rubles. The tool is good when solved how to cut drywall at homein a straight line. Figured lines by mounting knife are across ababy as. Let's proceed:
- Cut the plasterboard at previously made tags.
- Put to one side of the markup of the steel profile for drywall or metal ruler. They will not give the knife to go away during the cutting.
- We put the blade to the edge of the markup and lead along it with a pressure of about 3 kilograms.
The knife should not pass through the sheet. Right cut drywall - This is a blade with a deepening in about half acetimeter. The rest is deeply over the line when I will bend the panel with your hands.
The cut at the same time should be up. For bend, plasterboard will be needed to be opened. You can simply put a sheet on the floor, and you can put on the chairs or the edge of the table.
Nuances cutting plasterboard depending on his type
Sheets of plasterboard are specialized, for example, waterproof. Paper on such impregnated with polymers. They close the pores in the cardboard, making it resistant to moisture and reliable protection for inside the compressed gypsum powder.
However, the edge even is not protected from the waterproof drywall. Accordingly, the workplace should not be wet. Once in the gypsum, water will lead to its swelling, change the geometry of the construction sheet.
Arched plasterboard
Separately stands arched plasterboard. It is as thin, only 6.5 millimeters in thickness. It would seem that such a sheet is cut easier than a centimeter. However, fiberglass is laid inside the arched panel.
It reinforces drywall and gives the flexibility necessary to deform a sheet intended for curvilinear doorways, ceilings.
Because of the fiberglass inside the arched material cuts the harder of the simple drywall. It is better to use the power tool. The mounting knife or the handset "go" is hard.
General rules cutting plasterboard
Microparticles of plaster inside the cardboard cover are light and volati. Touching from under the paper during cutting, the mineral suspension rushes into the air, falling into the eyes, settled in the airways. Therefore, it is desirable to fit in a protective mask.
On the floor under the cutting cannol, it is recommended to lay a polyethylene film, a slightly sprinkling with water from the sprayer. Moisture helps flying on top of the particles of gypsum to swell, sneeze and drop on polyethylene. At the end of the work, it will remain minimize and throw it out. Particularly crushed washed the film in the bathroom, dried and used again.
If the plaster dust falls directly to the floor, laundering the powder will be problematic. Divorces will remain. If there is a porous coating of the type of matte porridge, the gypsum particles will be born into it.
The saving water is becoming a solution of warm water with sunflower oil at the rate of a half-table of a product for 10 liters. After the floors wipe with acetic solution.
For glossy surfaces, the method does not fit. It is better to do with a solution of manganese. It is added to warm water until it becomes light pink.
Cut the profile for plasterboard
Once began working with the hero of the article, the question is also relevant, how to cut a profile for drywall. It is used to create a frame for paper-mineral sheets.
They are attached to the profile of them on the self-tapping screw. Accordingly, the plasterboard closes the profile basis. You can not focus on the accuracy of cutting steel rods. Their unsightliness will hide sheets.
Cut the profile with metal scissors
For cutting profile under plasterboard use 3 tools:
Scissors for metal. They are good for cutting sheet steel. Working with P-shaped profiles for gypsum sheets is uncomfortable, but is profitable. Manual version of the tool resembling plugs, costs from 200-meters. Also, the inconvenience of work with scissors smooth their independence from the mains and silentness.
Electrolzik. Cuts carefully and quickly. Working with the tool is convenient only with tight profile fixation. It is made of fine steel. If this will "walk" under the blade of the jigsaw, the cut is uneven.
Miniature Bulgarian. In working with the Bulgarian profile put on bending. In other words, the cut part should hang over the air and bend under its own weight down as cut off. The rest of the profile rests on the chair, the table.
Estabilities in the handling of the power tool eclipses the noise emanating from it. However, you can wear headphones. Of the obligatory means of protection it is worth mentioning glasses.
Cut the profile of a small grinder
Chips can fly from the treated steel. She can get into the eyes, damaging them. Such pieces of metal are called skills, removed in the injuries.
The danger of a profile cutting with an electric tool consists not only for damage to human health, but also decoration of the apartment. Chips from steel flies hot.
Each of us has ever been repaired in his life. And many make it every couple of years. For insulation of your home or creating beautiful shapes on the ceiling, in the bathroom or any other rooms, we often use such material such as plasterboard. And many of those who prefer to make repairs with their own hands, wondered, and whether it is possible to make a cut of the plasterboard on their own at home, and how difficult it is.
Most often, the owners resort to the help of foreign people (specialists), spending big money at the same time. This article will help you to cope with this process, do not spend time on the search for specialists, and will help you get exactly the result you want.
Features
Plasterboard is a relatively young material used when performing construction work. He acquired wide popularity due to its harmlessness, versatility, good sound insulation. Helk himself, how can I understand the name, consists of two sheets of dense cardboard and gypsum placed between them. The standard width of one sheet is one hundred twenty centimeters. Since the plasterboard has large sizes, when conducting construction work, you have to resort to its cutting.
For cutting on plasterboard, we will need a roulette to get the desired dimensions (a ruler can also be used), a pencil, a pen (or any other similar tool), with which we will apply the figures you need to leaf, tool for the very cut itself (hacksaw, Bulgarian, Lobzik, cutter), ripping planer (for processing edges after cut), saw (may be circular or ring), or the drill with the crown. The slice-carcarton section does not represent any difficulties, but its incorrect cutting leads to a large overflow of the material, and, accordingly, to the excessive waste of cash.
The incision of G Clac is not a labor-intensive work, any newbie with a proper desire is able to make a cut itself without resorting to the help of professionals.
A brief process of cutting drywall is as follows. First, there is a cutting of plasterboard, after a dun. Also, the simple composition of the drywall is easily drilling, which is necessary to do various holes.
This type of material is divided into various species depending on the functions endowed:
- moisture-resistant;
- standard;
- fire-resistant;
- acoustic;
- increased strength.
Moisture-resistant plasterboard is needed when used in rooms with an increased number of vapors in the air. Fire-resistant plasterboard is used where there are fireplaces, and near places with sources of open fire.
Initially, plasterboard was used only for aligning surfaces.
There are three standard sheet types:
- 3000x1200 millimeters;
- 2500x1200 millimeters;
- 2000x1200 millimeters.
Depending on the type of drywall, their thickness differs, which affects the complexity of cutting.
Ceiling plasterboard has a thickness of 9.5 millimeters, wall - 12.5 millimeters, arched - 6.5 millimeters.
Consider several features when cutting drywall:
- It is necessary to have a sheet of drywall on a flat and stable surface, as it is very flexible.
- If the drywall sheet has a large size, then the cutting must be performed gradually.
- Before laying the sheet on the working surface, make sure that it is dry. The wet sheet will be unsuitable for work.
- Cutting is recommended from the other side that will be located at the wall. This will subsequently hide the possible shortcomings formed during cutting.
- It is necessary to protect with the means of individual protection of the eye and respiratory organs.
When cutting drywall, it is not allowed to use a circular saw due to its ability to create a large amount of harmful dust.
What is better to cut?
The cutting of plasterboard is made by various types of tools, one of them are:
- mounted knife;
- hacksaw;
- electric jigsaw is a manual power tool, with which the various types of materials are carried out when using the reciprocating movement of the saw blade.
Consider separately each of them.
Mounting knife
In this way, we will need a drill and, in fact, a mounting knife.
To cut the plasterboard with a mounting knife, it is necessary to measure the required size of the drywall in length or width. We also need a metal ruler. We apply it to the cut line. After that, a section of this material is made. The process itself is quite simple, it will not take a large amount of time. The neakkurat region, left after the cut, can be corrected using the plane. It is recommended when dummary of drywall on the table so that the edge spoke on one or two centimeters, and with cutting on the floor, to put any item resembling a bar for it.
When cutting drywall, one person is quite convenient way is a cut of the part on one side, after which the plasterboard neatly turns over to the other side and continues to cut on the other side. This method allows, if necessary, cut into thin strips of plasterboard with minimal damage.
Hacksaw
This tool will allow us to cut only small figures, such as a circle, square, rectangle, rhombus and others. To achieve the best result, it is recommended to use a hacksaw with a thin blade.
The figures of the appropriate size we need, after which, with the help of a drill, we do a hole corresponding to the size of the blade of our hacksaw. After that, cut out the figures you need. Just as in the previous method, it is possible to use a planer to achieve neat edges or a file, if the size of your parts is too small. It is recommended to use the metal hacksaw, but when it is absent, it is possible to use hacksaws and wood.
This process can be described in more detail as follows.A sheet of drywall is placed on a flat surface (you can use a stack of plasterboard sheets). Next, the necessary measurements are made, and the dimensions are applied with a pencil (or any other subject) onto the sheet. Marks are applied on both sides of the sheet, starting with the edge of the sheet. Next, they are connected to each other, forming the desired line or the shape. In some cases, use a marking thread. Lines are placed on both sides of the plasterboard.
The next step is carried out directly cutting plasterboard. The length of the blade of our tool should not exceed the sheet thickness. A leaf is cut with a knife (preferably several times to achieve the best effect), the sheet turn over the other side. Next, several times knocking along the cut line, and cut the remaining part of the plasterboard with the same knife.
Electropolitanzik
Cutting electric jigsaw is the most fast of all, but at the same time quite costly. Its price varies from 1500 to 10,000 rubles. The price depends on the quality of this product. But the costs absolutely justify themselves. Our possibilities are significantly expanding. There is an opportunity to cut lines and figures of various forms, including curved, the amount of waste is also significantly reduced. When working with the jigsaw, it is necessary to follow safety. And before starting work, check the integrity of the wires and the serviceability of the tool.
To achieve the desired effect, we apply properly necessary forms or pictures on the garcoton sheet.Next, place it on two stools (or any other supports) placed on both sides of the sheet. After that, with the help of an electric batch, cut out the figures we cut.
When cutting round holes, it is recommended to draw them with a circulation, and when cutting, drill a hole inside the circle. The edges after cutting drywall need minimal processing, which also saves our time and strength, being a significant plus.
When cut, it is not recommended for a long time to linger in one place, as well as pressing onto the sheet, applying great power, to avoid breakdowns of the electrolovka and leaf. It is necessary to carefully process the edges of the GCC before hanging, for example, a point lamp or a socket.
Subtlety of the process
When cutting plasterboard, it is customary to comply with some rules, such as:
- placing a sheet on a flat and stable surface;
- the surface must be dry and without excess garbage;
- use personal protective equipment for eyes and respiratory organs, as a large amount of fine garbage and dust remains with cutting.
When carrying out a cutting profile, various types of tools are used:
- Hacksaw. This type of tool, regardless of whether it is narrow or wide, has a high flexibility of the cutting blade, which allows it to deviate from the specified direction. This reduces the quality of work, and also increases the time spent on cutting.
- Bulgarian. The tool is one of the best in the construction of construction works, including when cutting drywall.
- Metal scissors
- Lobzik.
Also in our life, the moments in which it is necessary to make a cut on the already installed sheet of plasterboard under the luminaire, paintings or any other things. This case also has its own way.
First you need to make sure of the reliability of the plasterboard mount, after which the fine holes we need are neatly cut with a jigsaw, a drill with a nozzle or an electric drill. Large holes are recommended to be cut into a knife on the applied markup. Upon receipt of uneven edges, they can be removed by the emery or hacksaw.
When cutting circles there are a number of nuances. The simplest way to cut in the drywall of the circle is to apply the desired size to the sheet, and then carefully cut in a circle with a blade, and knock the core to the hammer (with small efforts with any similar subject). There is also the easiest way to save time and power - the use of a drill with a special cylindrical nozzle. This type of nozzle is usually used when embedded in the door of the locking mechanism with a snatch.
There is also a so-called double-sided incision, which is carried out when there is a sheet of different obstacles on the path, be it door, opening, beam or any other. If such a situation has occurred, it has to make a cutout (or a cut) from the right side and the necessary form. This manipulation is performed simply enough, but requires concentration, accuracy and care. One side of the sheet must be powered with a hacksaw, and the other side is neatly cut through with a knife. After completing the work, making a dormant and processing the edge of the plane.
When cutting drywall - it develops. It is advisable to do it carefully without damaging the sheet. There are three possible ways of flexing drywall. To the easiest way, the method of applying the desired workpiece to the profile and fixes it in the desired position by self-draws. This method is used with small sheets of 20-30 centimeters and a slight arc size.

Plasterboard is one of the most common materials in the construction, which is nevertheless very fragile. With the help of it, not only the ceilings and walls, but also create a wide variety of home interior decorative elements. However, its non-accurate cutting leads to the overfers of the material, and the inability to produce it - to externally, the cost of helping the specialist. But do not get upset, because it is not difficult to cut the plasterboard with your own hands, if you make sure to follow the specified instructions.

Principle and rules cutting drywall
Save.
The principle and rules of cutting are based on an understanding of what you are dealing with, so you must first examine the structure of the material. But in this case, the name speaks by itself - two outer layers are formed by cardboard, which serves as the basis of relative strength, and there are plaster with fillers between them. For various purposes, different types of drywall are used: standard, waterproof, fire-resistant. The first is used in all cases, excluding the walls of the walls and the ceiling (there are moisture-resistant plasterboard) and structures in close proximity to the fireplace or other heat source (in this case there is a fire-resistant material).
Preparation and drawing
Place a sheet of GLC on a flat horizontal surface and apply tags using a simple pencil, roulette or ruler. It is suitable for this procedure a marker and fountain pen, but their traces are visible under putty.
Save.
Directly before or while working, select the tool to be cutting. You have many ways to perform the fulfillment of the funds occurring depending on your own. In fact, cut the plasterboard can be any sharp object, but for this you will need certain skills. Consider the basic tools from those that can be used.
What to cut off: tool selection
If you are going to cut off drywall on a regular basis or at least quite often, it is recommended once to purchase a professional tool and do not suffer with appropriate means in the future. In any other case, you must have a stationery - construction, reinforced - or mounting knives. Types of stationery are barely distinguishable among themselves, but the construction is stronger. However, in any case, the cut from this knife is such that after it is necessary to eliminate the formed jar.
For the work done, the metal was completely applicable to the metal - her blade thinner than the tree hacksaw, so it wins in the accuracy of the following result.
Another useful device is an electrolovik. His advantage in the absence of need to think how to cut drywall, because you just need to lead along the drawn line. For edge processing, additional tools are used like a relief ruble, the effect of which may well be reproduced by sandpaper.
When we figured out than the plasterboard cut, you can go directly to the methods of its cutting, the number of which is also large and varied. Consider some of them.
How to cut the mounting knife
Save.
The mounting knife is suitable for cutting drywall to large longitudinal parts. First, make the necessary measurements using a roulette and a pencil, attach the metal line to the stressed line and start cutting the material by the edge along the edge of this line itself.
Save.
Be careful and do not hurry so that the incision is left smooth and accurate and coincided with the line from the pencil stylus.
The core is abandoned with a slight tapping, then the plate turns over, and the plasterboard is cut off again on the distance. At the end, the material should be treated with a planer so that the edge becomes smooth.
How to cut a knife
Save.
It is worth noting that most often the knife is used to cut rectangular openings. In this case, you need to draw plasterboard from the back. In one of the corners of the drawing drill, do the diameter hole so much so that the hacksaw can calmly go there. You can also do holes on all parties. After the operation is completed, the edge, as in the previous case, is processed by a planer or a file depending on the size of the hole done. Important: The tool can be preferably perpendicular to the plane plane of the plasterboard sheet. In this case, the edges come out evenly.
Save.
Cutting electrolovka
Save.
The electrolovik is the tool that will help save time and your energy. Applying it, cut and cut can not only direct, but also smooth, curved lines and various figures. If you use it, put a sheet of HCL into two stools so that the shape of the desired cutting line is drawn up to the distance between the surfaces of the stool. Act smoothly and leisurely, cut out strictly on the intended line. The electrolovka has another significant advantage: with it the processing of the obtained edges is minimized, because it is held perpendicular to the surface of the sheet, which is the key to such a result. This contributes to a special sole installed in it. By cons can be attributed to the fact that it will still have to spend money, but this tool is worth it. Also when working with it a lot of dust rises, you should take care of the means to protect the eyes and respiratory organs.
Figured cutting, as well as square and round cuts
It is worth paying attention to the above-mentioned curly cutting. To cut the best of all, will definitely fit the electrolovka. But if the figure is, for example, a conventional circle, it is acceptable to use an ordinary stationery or mounting knives. Initially, it is important to determine the center of the circle, and then with the help of a pencil and circulation, draw it. Top of the knife as much as possible to shift the contour of the outlined opening. Then post this area over the empty space - a design of two stools is suitable here. Sleep up the cutout with a hammer - the material breaks down in the center of the hole.
Edge treatment
The cut is treated with a relief brang, as the edges never go out sufficiently smooth and neat - this is the property of any tool, the experience and skills of the artist playing a smaller role here. You can remove the chamfer and using an ordinary knife, but it will take more time and requires professional skills.
Save.
In conclusion, it should be noted that the cutting of drywall is one of the most common operations in the list of those that can easily be performed independently at home without resorting to the help of a specialist. It is enough to approach any work with the mind and patience and carefully familiarize themselves with the sequence of fulfilling the task, relying on its features. Then the result will be appropriate.
