How To Cut Drywall At Home

The cutting knife is suitable for cutting drywall into large longitudinal pieces. First, take the necessary measurements with a tape measure and a pencil, attach a metal ruler to the drawn mowing line and begin to cut the material with a Point along the edge of this very ruler.

The core is broken with a light tap, then the plate is turned over, and the drywall is cut again at the broken place. At the end, the material should be processed with a plane so that the edge becomes even.

Shaped cuts as well as square and round cutouts

It is worth paying attention to the figured cutting mentioned above. To get the best dust, a jigsaw is certainly suitable. But if the figure is, for example, an ordinary circle, then it is acceptable to use an ordinary clerical or assembly knives. Initially, it is important to determine the center of the circle, and then draw it with a pencil and compass. Using the edge of a knife, cut the outline of the intended opening as much as possible. Then Position this area over the empty space. a two-stool design will work again. Hit the cutout lightly with a hammer. material will break through the center of the hole.

How and what to properly cut drywall at home

Drywall is one of the most common materials in construction, which is nevertheless very fragile. With the help of it, they not only sheathe ceilings and walls, but also create a wide variety of decorative elements of the home interior. However, its inaccurate cutting leads to a waste of material, and the inability to produce it leads to unnecessary costs for the help of a specialist. But do not be upset, because it is not at all difficult to cut drywall correctly with your own hands, if you follow the given instructions exactly.

Preparation and marking

Lay the plasterboard letter on a flat horizontal surface and mark using a simple pencil, tape measure or ruler. A marker and a fountain pen are suitable for this procedure, but their traces are visible under the putty.

Directly to or during work, select the tool that will be used for cutting. There are many ways to accomplish your plans, depending on the means at your disposal. In fact, you can cut drywall with any sharpened object, but this will require certain skills. Let’s consider the main tools from those that can be used.

Jigsaw cutting

The jigsaw is the tool that will help you save time and energy. By applying it, spray and cut can not only be straight, but also smooth, curved mowing lines and various shapes. If you use it, put a sheet of gypsum board on two stools so that the fishing line drawn before this in the shape of the desired cut passes in the distance between the surfaces of the stools. Act smoothly and slowly, Cut strictly according to the intended mowing line. The jigsaw has another significant advantage: with it, the processing of the resulting edges is reduced to a minimum, because it is held perpendicular to the sheet surface, which is the key to such a result. This is facilitated by the special sole installed in it. The disadvantages include the fact that you still have to spend money on it, but this tool is worth it. Also, when working with it, a lot of dust rises, you should take care of the means for protecting your eyes and respiratory organs in advance.

Principle and rules for cutting drywall

The principle and rules of cutting are based on an understanding of what you are dealing with, so you should first study the structure of the materials. But in this case, the name speaks for itself. the two outer layers are formed by goods that serve as the basis of relative strength, and between them is gypsum with fillers. For different purposes, different types of drywall are used: standard, water-resistant, fire-resistant. The first is used in all cases, excluding wall and ceiling cladding (moisture-resistant drywall is used here) and structures located in the immediate vicinity of a fireplace or a second heat source (in this case, a fire-resistant material takes place).


The cut is processed with a roughing plane, since the edges never come out smooth and neat enough. this is already a property of any instrument, the experience and skills of the performer play a lesser role here. You can also chamfer with a regular knife, but this will take more time and requires professional skills.

It should be noted that cutting drywall is one of the most common operations in the list of those that can be easily performed independently at home, and without resorting to the help of a specialist. It is enough just to approach any work with intelligence and patience and carefully familiarize yourself with the sequence of the task, based on its features. Then the result will be corresponding.

Good luck and successful repair.

How to cut with a hacksaw

It should be noted that most often a hacksaw is used to cut rectangular openings. In this case, you need to outline the drywall from the back. In one of the corners of the drawing with a drill Make a hole of diameter so large that the hacksaw blade can easily enter there. You can also punch holes on all sides. After the end of the operation, the edge, as in the previous case, is processed with a plane or a file, depending on the size of the hole made. Important: it is advisable for the tool blade to be perpendicular to the plane of the drywall sheet. In this case, the edges come out smoother.

How to cut: tool selection

If you are going to cut drywall on a regular basis, or at least often enough, it is recommended to purchase a professional tool once and do not suffer from improvised means in the future. In any other case, you should have clerical. construction, reinforced. or assembly knives. The types of stationery are hardly 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 notches.

A hacksaw for metal is quite applicable for the operation being done. its blade is thinner than that of a hacksaw for wood, so it wins in the accuracy of the subsequent result.

Another useful tool is a jigsaw. Its advantage is that there is no need to think about how to cut drywall, because you just need to guide along the drawn mowing line. For processing the edges, additional tools are used, such as a roughing plane, the effect of which can well be reproduced with sandpaper.

When we figured out how drywall is cut, we can go directly to the methods of cutting it, the number of which is also large and varied. Let’s consider some of them.

In a straight line

Before starting work, you need to take measurements in the room so as not to make mistakes when cutting parts. Use a pencil to mark the cut line. Marker or pen Best not to use. Caustic ink leaves marks that show through the putty.

Upon completion of the calculations and applying the appropriate markings, the drywall is placed on a surface parallel to the floor. It is more convenient to use a construction knife for cutting, since the sharp blade can adaptively adjust during operation. It should be remembered that the length of the sharp should not exceed the thickness of the drywall. It is recommended to make an incision using a metal ruler that fits over the pencil markings. To create a flat mowing line, an additional cut is required 3 times with the tool.

In the case of placing a layer of drywall on the table, it is necessary to move the gypsum so that the separated part of the day does not come into contact with the table surface. Once the cut is deep enough, grasp the edges of the drywall and break along the mowing line with a sharp motion. For the final cut from the opposite side, make an additional cut with a construction knife.

When sawing drywall on the floor after additional movements, the drywall product must be placed in an upright position. The cut out part with a neat push on the front side must be separated from the unnecessary one (make a break). Then the unseparated fragments are cut with a blade.

The letter “G”

The shape of drywall curved with the letter “G” is used for facing a door or window opening, as well as when creating any corner model.

The work begins with calculations and marking the mowing line with a pencil. For implementation, you can use a hacksaw if you have a specially serrated drywall saw at hand. Gypsum is a soft pliable material that does not cause cutting problems.

Holes for lamps and sockets

Specialists cut holes for sockets or lamps after installing and fixing the drywall. For beginners, you can do without prior fastening. For this purpose, it is first necessary to accurately calculate the position and parameters of the future hole.

All calculations must be applied from the back of the drywall. For the cutting itself, you will need a screwdriver or drill. The tool should have additional circular bits with fine serrated blades. In the absence of a pistol, a classic hacksaw will do. The holes are uneven but match the calculated parameters. All flaws are covered with a canvas.


The job does NOT end with cutting drywall. Sharp and uneven edges need alignment. You can handle nicks and chips with sandpaper.

It is recommended to level it with gentle movements until a smooth surface is achieved. At the end of the preparatory stage, fascination is performed. Two-thirds of the thickness of the drywall sheet must be cut off at each end. Next, a chamfer is cut off at an angle of 45 degrees with a plane. If there is no suitable tool, you can use a regular knife.

READ  Start Machine From Cordless Screwdriver

After sanding the edges, place the drywall in the desired position. However, at this stage, numerous cracks appear, which require putty. Once the material is completely dry, the surface of the drywall is primed for additional reinforcement. Then they start painting or glue the wallpaper.

On the wall

If necessary, the plasterboard section of the window opening or the corner of the wall is cut by the gypsum board directly on the bearing surface. In this case, the plaster edge coincides with the edge of the wall. To create such a model, a piece of drywall is used larger than required. The material is attached to the wall surface, after which excess elements are cut from the plaster.

The procedure requires a secure attachment to the supporting surface. Cutting begins from the side of the plasterboard sheet, which fits snugly against the support. Pressing on an unnecessary part, it is necessary to run several times along the marked mowing line. After that, the remaining elements of the cut are cut off from the reverse side.

How and what to properly cut drywall?

Plasterboard installation requires the creation of parts with different configurations. At home, such decisions are rarely made by the owner of the apartment, so it is impractical to purchase expensive electric saws. General tools are suitable for cutting.

Uneven line

When cutting drywall in the form of a wavy curved mowing line, you cannot do with an ordinary hacksaw or a construction knife. During their operation, smooth bends are uneven. To achieve a perfectly flat surface, you need to purchase or rent a jigsaw with fine blades. In doing so, the tool creates a huge amount of gypsum dust. Because of this, you need to take care of personal protection of the eyes and lungs.

The front surface has an increased density in comparison with the seamy side of drywall. Because of this, the arcuate part is bent in such a way that the back surface of the material is stretched. To bend the future arch exactly, you can resort to a template. The latter is made from plywood.

Then proceed according to the Step by step instructions:

  • On one side, the arc is bent with a needle roller. In this case, it is necessary to constantly press on the drywall. The roller needles will penetrate the plaster material up to 5 mm.
  • At the end of the work, the surface of the drywall is moistened with water until softened. This stage takes a long time and patience. As the drywall swells, gradually bend is required.
  • As soon as the part settles tightly in a template form, it is fixed until completely dry.

For sloping elements with a radius of more than 40 cm, the bend turns out to be not so steep, thus the manufacture of the part does not require additional wetting. It is possible to implement identical wavy type elements using transverse cuts. It turns out an accordion that needs to be fixed with a primer. When folding drywall, all cracks must be putty.

Achieving a perfectly round hole is easy with a drill with special drills. The nozzle is perpendicularly pressed against the surface of the drywall. When pulling the trigger, begin to drill a hole.

The drill is NOT capable of creating large diameter decorative holes or rounded parts (for example, wavy elements). A hacksaw can easily cope with a similar task by cutting the internal elements. To do this, you need to cut the fishing line and insert a canvas with pencil markings. Then it is sawn according to the markings.

It is inconvenient to work with a drywall with a hacksaw on the floor, so it is more optimal to put the GKL letter on the table. over, the plaster will have to be laid in such a way that the cut out part is outside the countertop.

Tool selection

In industrial plants, drywall is required in large volumes. Therefore, special hardware installations have been developed for cutting gypsum boards. At home, everything is much simpler. handy tools are used, which can be found in every apartment.

So that at the end of the work DO NOT additionally cut out every detail, it is necessary to cut the drywall as evenly as possible. To achieve this goal, markings are marked on the plaster with a pencil and a centimeter tape. If there is the latter among the tools or the length of the drywall exceeds 2.5 m, then the surface can be marked out thanks to the metal profile.

Several tools can cope with cutting drywall:

  • Cutter (hacksaw) for metal or wood;
  • Jigsaw;
  • Construction knife with replaceable blades;
  • Electric drill.

The latter tool is suitable for drilling a small, straight circle. As the radius increases, it is necessary to use pen drills or rounded saws.

The electric drill is suitable for creating holes for the core of door locks. An ordinary hacksaw for metal or wood is capable of cutting drywall. The tool features a thin blade with a dense row of teeth. A minimum distance is maintained between sharp ridges to prevent chipping.

Thick sheets of drywall lend themselves to cutting with a construction knife. The device is convenient in operation due to the double-sided sharp blade. Over time, the core becomes dull, however, manufacturers put several additional elements inside. Therefore, if necessary, the blade can be easily changed to a new one.

To cut drywall with a construction knife, markup is required and put a metal ruler along the pencil mark. Holding the profile, make an incision with a knife. If the plaster is thin, the construction knife can be replaced with a clerical.

Correct cutting

A few simple rules will help you to cut drywall correctly:

  • Working with plaster requires resorting to safety measures. Even a small cut or small fracture crumbles the material. At the same time, dust is released, which is dangerous for the body. Protect eyes and lungs with goggles and a respirator mask.
  • It does not matter which side the drywall is dusting. However, experts recommend starting from the surface that will be in contact with the wall or ceiling.
  • Cutting the profile leaves uneven edges. It is not worth wasting time on aligning them, because Subsequently, the flaws are hidden with drywall.
  • Cut drywall sheets in dry rooms. In high humidity conditions, the material swells quickly and becomes unusable even after drying.
  • It is possible to correctly cut flexible drywall on a stable surface with an even relief.

The facing material itself consists of two layers of cardboard. They are covered with a thick plaster layer. This structure provides fire resistance and strength by increasing the density. Consequently, to implement a point cut, it is enough to deepen the cut with a sharp blade several times with accurate movements from top to bottom. After which the letter needs to be broken along the cut line cut. In this case, it is important to keep drywall in one position, do not let the blade move when cutting the cardboard layer.

How to cut a circle in drywall

If you have a drill with a special attachment at hand, then small round holes can be drilled very easily. The cutter is pressed against the letter strictly perpendicularly, then the drill is turned on and slowly pressed from above. In total, it turns out a little dusty, but perfectly even.

Do NOT drill round holes or mowing lines of complex configuration (waves, patterns). Here you will have to act with a hacksaw on the principle of cutting out an inner piece. The fishing line is drilled out, the canvas is inserted. Then they saw on the drawn.

Naturally, it is inconvenient to do such work on the floor. You can put drywall on the table so that the cut protrudes beyond the edge of the tabletop.

Some craftsmen cut a round hole in the cardboard with a knife, and then knock it out using the usual method. Beginners are NOT advised to try to repeat this procedure. Without proper skills in drywall, an ugly gap with torn edges turns out instead of a perfect circle.

Council. DO NOT attempt to cut openwork mesh or intricate patterns with thin lines in drywall. The material may simply not stand up. The letter is strong only with a large pattern of wide lines.

Description of the cutting process

Use a tape measure to measure the desired distance. A mark is drawn with a simple pencil. Once again, they will double-check everything, because there will be no possibility to fix the work.

Then they take a clerical knife and cut the cardboard along the mowing line of the marking. If there is any doubt about the hardness of the hand, then you can cut along the guide. It is very convenient for this to use the rest of the profile for fastening to the wall or a long building level. Sometimes one effort is not enough, after all, drywall is a fairly durable material. Then cut through several times.

DO NOT try to cut drywall immediately with a knife. It’s impossible. There is a hammer for such work. All you need is that several times it will lightly hit the cut on the back of the sheet. The plaster base will crack safely exactly along the cut line.

All that remains is to turn the letter upside down and cut the second layer of cardboard with a knife. Everything is ready.

For a better joint of the pieces, the cut must be cleaned. Sometimes quite large notches remain there. Aesthetically, they DO NOT interfere, because all the same, the seam will be putty. But connection accuracy can be affected.

Chamfering is the name of this procedure. It can be easily done with sandpaper or a large file. But we recommend purchasing a special plane for such purposes. over, it stands very democratically.

Cleaning the incisions is performed with smooth movements, without strong pressure. Don’t try to achieve perfect smoothness. It is enough to remove large rags.

Someone will ask: why was a hacksaw needed? For cutting through holes. You can’t just knock them out with a hammer. Practice shows that drywall writing breaks anywhere, but not on the markup. For through holes, the execution technique is slightly different.

A hole is drilled in the sheet along the mowing line of the marking so that the hacksaw blade fits. Then, with the same hacksaw, cut out three sides of a square or rectangle. The fourth side cannot but get dusty. It is enough to cut through the cardboard on one side with a knife, and then knock out the Unnecessary piece with a hammer. The cardboard on the other side is also cut with a knife.

In the same way, corner squares and rectangles are cut out in drywall. Cut one side with a hacksaw, the other with a knife and hammer.

Council. There will be very few jagged edges at the cut if you hold a knife or hacksaw perpendicular to a drywall sheet. The lower the blade tilts, the larger the rags will turn out later.

How to cut drywall at home

Many people align the walls and ceiling with drywall at home. Fast, convenient, perfectly straight. But the sheets are large and do not always fit exactly the size. Or you have to make a hole for an outlet, a lamp, attach a small piece.

Cutting professionals have special power tools, but they are always obscenely expensive. What should ordinary people do? How to cut drywall at home? In fact, it’s not as scary as you think. If desired, everything is quite doable in a few minutes. And the most common tools will be needed.


Preparatory work is happening very quickly. First, the tools are selected so as not to run in search. You will need:

  • Tape measure, building meter or ruler.
  • Simple pencil, nail, self-tapping screw. Any item that leaves a visible mark.
  • Knife. Stationery or construction (it is more reliable).
  • Hacksaw. Preferably narrow, but with a stiff blade. You can take the one intended for cutting knots.
  • A hammer. The most common.
  • Special plane. Easily replaced with a file or medium grit sandpaper.
  • Drill. If there is a special nozzle-cutter for it, it will be great.

Then the drywall lettering is laid on a flat surface. For example, on the floor. Experts can cut drywall by weight, I do not recommend this technique for beginners. Fraught with damage to material.

If there is no space on the floor (this happens during repairs), then the letter is placed on two stools. Strictly the same height. And they start.

Helpful hints

  • Some people manage to cut drywall at home with an angle grinder. We do NOT recommend doing this. There will be a lot of noise and plaster dust. With a simple knife and hammer, it turns out much cleaner and more accurate. And you will NOT need somewhere to get personal protective equipment and the ability to work with a power tool.
  • Glasses, plates and saucepan lids serve as excellent templates for marking circles. Just pick the right size and draw the line of the circle. This is in case there is no compass at hand.

How to cut drywall at home? Very simple. Accurate measurement and a firm hand are the main components of a known success. And everything will work out with a bang.

How to cut drywall at home

Many who independently made repairs in their house or apartment know firsthand what drywall is and how sometimes it is not easy to work with it. Those who are just planning to start repairs have to find out. Drywall is a rectangular sheet, the core of which is gypsum, and both sides are building board. It is suitable for decorating walls, room ceilings, partitions, and various decorative elements. This material has a perfectly smooth surface, thanks to which wallpaper and paint fit well on it. But any use of it requires cutting out. Drywall is a very fragile material; care must be taken when transporting and working with it. Therefore, we will figure out how to cut drywall and how to cut drywall at home.

Tools play an important role in cutting plasterboard. If chosen incorrectly, drywall can be irretrievably damaged.

General recommendations

  • Drywall is flexible, so that during work it is laid on a flat and stable surface
  • Cut a large sheet of plasterboard gradually
  • Make sure that the workplace is not damp. the letter will get wet and it will no longer be possible to use it
  • Which side to cut drywall? Best of all with the one that will be on the side of the wall
  • Protecting eyes and respiratory system from generated dust

The better to cut drywall

How can you cut drywall? The following tools may be useful for work:

  • Construction knife
  • Hacksaw
  • Jigsaw
  • Electric drill, milling cutter
  • Plasterboard planers

Also, before work, prepare a simple pencil, tape measure or thread for taking measurements, a long metal ruler or level for a straight cut.

Important! GCR can not be cut with a circular saw, it creates a huge amount of unnecessary and harmful dust.

How to cut drywall in a straight line with a cutting knife

The tool for cutting drywall must be chosen, taking what shape you want to give it. If you need to cut it along a straight longitudinal mowing line, a cutting knife will do, but working with this tool takes time and effort. If there is not much such work, the knife will cope with it, but if you need to cut drywall in large quantities, then you will have to spend a lot of time.

  • Lay drywall on a flat, stable surface, apply markings on it;
  • Press a metal ruler or level against the drawn mowing line, move the knife alongside, going deeper into the core.
  • Turn the sheet over, fold it into the slot towards the uncut side, so the plaster middle will break to the end;
  • Cut the uncut cardboard with a knife.

How to cut a hole in drywall. round or rectangular. Curly cutting

How to cut a square in drywall? You can cut a square or rectangular opening with a hacksaw. this is a good tool for cutting drywall. The thinner it is, the better. To do this, you need to draw a future opening, make holes in its corners with a drill so that a hacksaw can enter. Cut from one corner to another. It is better to choose a hacksaw for metal, it has more teeth, which means that the cut will be more accurate. The hacksaw should be held perpendicular to the drywall sheet. This will make the edges smoother and less chipped.

If you have a jigsaw, using it will make your job easier. This cutting method is considered the fastest and easiest. It can be used to cut curly mowing lines, not just straight ones. This is the best way to cut drywall. To do this, draw a letter, place it on two stools, leaving a space between them so that the jigsaw teeth pass in this space. If you use the jigsaw carefully, the edges of the cut sheet will be the most even and neat. Choose pollen on a jigsaw for metal. You need to be prepared for the fact that when working with this tool there will be a lot of dust, in advance Prepare safety glasses, a respirator, if there is furniture. Cover it.

For any curly cutting, an electric drill with a crown is suitable. Draw a hole, drill a hole, then use a hacksaw to cut through the drawn mowing line. Here’s how and how you can cut a hole in drywall.

To level and sand cut edges, use a plane or medium abrasive paper.

How and what does moisture-resistant drywall, fire-resistant or any other dusty? Cutting any other type of drywall is no different from cutting ordinary.

Sometimes it is necessary to make a cut not in a straight line of the mowing line, to cut the doorway (with the letter “G”), for example.

First, as always, we apply the markup. From the tools you will need a hacksaw and a mounting knife. Use a hacksaw to cut the shorter side. Cut the larger side with a knife along the intended mowing line. We break the letter in the opposite direction. Cutting the whole cardboard from the back with a knife.

In general, when thinking about how to cut a drywall wall, it is worth remembering that cutting drywall installed on a wall or ceiling is not very convenient. Cutting the gypsum core with a knife produces friction, which makes the process more inconvenient and laborious.

It often happens that beginners spoil more than one sheet before “filling their hand”. Therefore, let’s get to work, be sure to stock up on remarkable patience.

Choice of methods for cutting HA

Which method of cutting drywall to resort to will become clear after studying the options available for THESE purposes.

Cut to specified geometry

Shaped cutting of drywall is used in the situation of creating unique shapes for a specific structural element. This procedure is more complicated, and you cannot do without basic experience and a sufficient arsenal of tools.

When figured cutting, the material is first marked out. If you need to draw a circle, and there is a compass at hand, then they arm themselves with a needle and thread and a tied pencil.

For figured cutting of HA in different situations, one of the methods described below is applicable.

Option one. Describes the process when a hacksaw is selected as the tool. Manipulating a hacksaw is akin to working with a serrated knife and a handle. Using a drywall hacksaw, you can drink fragments with any non-trivial shapes (for example, butterflies or flowers).

Option two. An electric drill with a cylindrical nozzle allows you to create even circles of small diameter in drywall. The circle is marked here, but limited to a mark in the desired area.

Option three. For cutting GVL with a jigsaw, a clear marking of the contour of the required shape is performed. Priority in the choice of a jigsaw is given when the diameter of the circle to be made must be greater than the diameter of the crown of the Electric drill, and the rounded mowing lines of the forms are not limited only to a circle.

Option four. The most primitive, when the choice of tool comes down to a knife and a hammer. Drywall is cut along the outlined border. At the same time, they try to press on the blade as hard as possible.

Then the HA is placed on a flat surface with a depression. over, the detachable part of the element must fall into this hole. Less effective ghouls writing on the wall. Then hit with a hammer in the middle of the fragment to be separated. The part to be removed should break. A layer of cardboard is cut from the bottom, leveling the ends as necessary. The extreme GC masters do not recommend resorting to this technique for people without experience. Since you have to spend a lot of drywall sheets for stuffing your hand and working out the pressure.

Introducing the toolbox

The obligatory list of tools for cutting gypsum fiber with your own hands includes three groups of objects

Devices for applying markings on a GCR sheet. a simple pencil, tape measure, long ruler.

Cutting and sawing devices themselves.

  • Knife. You can cut GVLV with a clerical knife, as well as with a specialized construction knife with a double-sided replaceable blade (suitable for thicker materials).
  • Hacksaw. It is better if it is a tool for processing metal than wood.
  • Electric jigsaw. Ideal for cutting rounded parts. Least of all, high-quality saws for metal with a fine tooth leave chips at the ends of drywall.
  • Electric drill. Needed for making holes. For gaps of large d, you will need round crowns (which cut into the core of the door latches) and feather drills.

Edging devices:

  • Rough planer;
  • Chamfering planer.

This list clearly shows how the home craftsmen cut drywall. Of course, it is far from complete. The arsenal of experienced craftsmen may include professional equipment, for example, a special cutter for GVL. However, for those who are working with the material for the first time, this set is quite enough. In order to better understand how to cut drywall correctly, you need to clearly present the structure of this material.

Standard cut

Straight cutting. The easiest way to cut. It boils down to the following:

GVL is placed on a hard and flat surface. Then mark the future cutting line of the cut.

Whichever knife is chosen, they should be cut strictly, placing a ruler on the side. An uneven cut is guaranteed if you decide to handle it without a ruler. Cutting begins from the back side (here a thicker cardboard layer). The front part of the Civil Code is somewhat different, as it is intended for finishing work. When cutting the knife, try as deep as possible into the gypsum content.

At the end of the process, the GK is turned over and bent in the direction of the solid (without mowing line of the cut) side. The plaster, rather than being hit by the knife, will break in the desired direction. The cardboard from the opposite side is cut along the formed mowing line of the fold.

It is not particularly important which side to start cutting drywall. However, on a flat, dense surface, this is much easier to do than when holding the GL in weight.

Before you cut drywall with improvised devices, you should familiarize yourself with two more types of simple cutting, feasible for independent implementation.

Double-sided cutting. Most often, cutting in the form of any rectangle is performed in this way. Using a hacksaw, they cut one side, the other is simply cut with a blade. After that, the material is broken, and from the opposite side the cardboard is cut off (as in simple cutting). The finished cut is brought to perfection using an edging plane.

Cutting on uneven mowing lines. To cut material along uneven line, you must first prepare a drawing.

The nuances of making circles

Circles in the ceiling structure are made primarily for mounting luminaires. The easiest way is to cut a circle of a given diameter in the gypsum fiber with a blade. And gently knock out the middle part with a hammer. However, it will be easier to carry out what was conceived will be a drill with special equipment. a cylindrical nozzle. The same one that is used when cutting into the door of a locking mechanism with a latch.

Drywall cutting

Newbies in the construction business do not know how and how to cut drywall in the best way. After all, any work, whether it is the creation of a ceiling structure, partitions or a complex decorative element, requires knowledge of the rules for cutting gypsum boards and strictly following them in practice. The tool for THESE purposes is used differently. It all depends on the chosen cutting method. So, how to cut drywall at home, the recommendations below will tell you.

What is this article about

The structure and purpose of drywall

Gypsum plasterboard is a layer-by-layer combination of two types of materials. gypsum (inner content) and sheets of thick cardboard glued to it on both sides. It is clear that if the cardboard layers are damaged, cutting the rest of the day is not difficult.

Therefore, in order to be able to quickly cut out a sheet of gypsum board, it is not enough to know the best way to cut drywall. It is important to know the basic principle of this action: after the continuous even cutting of drywall is carried out, the second step immediately follows. breaking the letter.

Dusty drywall, like any solid porous material, is not difficult. It also lends itself well to drilling.

The functions of the material make it possible to differentiate it into varieties: moisture-resistant, fire-resistant, standard, increased strength (for example, gypsum board or gypsum board, performed using the Knauf technology), acoustic gypsum board, etc.

Despite the large assortment of GK, panels of any of its varieties lend themselves well to division into parts by means of the available material at hand.

Cutting after installation of gypsum board

Of course, the material is NOT fixed yet, it is more convenient to cut it. But in practice, there are situations when it is required to cut off the excess after mounting the sheets to the frame. Such trimming is due to the fact that the sheathed surfaces meet window slopes or corners on their way.

The letter is fixed on the wall, leaving a small margin of size. Already on the wall, remove excess centimeters.

It is important here to make sure that the HA is securely fixed to the frame. The cut is made on the side that is in contact with the wall. The cutting movements are repeated several times, following the markings. In this case, unnecessary parts of the material are trying to “squeeze out”. The letter is cut from the other side.

Having studied these methods, beginners will understand how to cut drywall with a minimum set of tools at home. If you need to cut large quantities of HA, these options will NOT work. The best solution would be to turn to professionals.

How to cut drywall. tools

We will immediately agree that we will talk about the most fundamental and ordinary things. The tools that are described in various books are not cheap for centuries and, in fact, they are needed by people who are professionally engaged in repair.

If you are NOT a professional or you need to make some minor repairs, then you can use the following kit:

  • The first is a tape measure and a pencil. Practically, these things are present in almost every self-respecting man. There are no requirements for them. The only thing is that the pencil must be sharpened, and the tape measure at least three meters.
  • The second is a metal ruler. Preferably the longer the better. If there is a ruler, then you can take it as an ordinary flat metal profile. The profile may remain when assembling the frames.
  • The third is the knife. If you choose a knife, you can use one of two options. You can take an ordinary clerical knife, and not too flimsy construction, or a special one with changing blades.
  • The fourth is a hacksaw. The saw can be any, ordinary for wood, even “dull”. The main thing is that it is NOT wide. The best option for this is a knot saw.
  • One of the professional tools, perhaps, is a roughing plane, designed for processing the edge of the cut. It is NOT advisable to replace it with any kitchen object such as a grater or a file. It is better to purchase such a plane, because the price is not high for centuries.

Now the time has come when we will talk about what can be made of drywall at home.

How and how to cut drywall at home

Gypsum cardboard is a very fragile material, which accordingly requires a careful and careful attitude towards itself. The main and big mistake in construction, where drywall is used, is its incorrect cutting, which leads to its deterioration and it is necessary to outbid excess.

But in fact, there is nothing difficult about it. Once I even had to give advice and conduct instructions over the phone, while Driving. People were faced with the fact that it was necessary to cut sheets of gypsum cardboard at home to different sizes, as a result, they solved this problem and got out of it.

How to cut drywall correctly

Its essence lies in the fact that this letter is reduced to certain sizes. This task is very easy and accessible. To do this, mark the desired dimensions with a pencil on both sides and put a ruler or profile and cut the top layer of drywall with a knife.

You do not need to cut the cardboard along the mowing line drawn with a pencil, it is better to attach a ruler and do it along it. Use the knife to cut 2-3 times to make the cut deeper. And only then the cut will turn out to be even and neat, it is possible that the cardboard can break in the right place for you.

Then put the letter on the cardboard edge, and approach it from the side where it is not cut and lightly knock on it. After a couple of blows, the drywall will break in the right place, clearly in size. There is little to do. cut off the cardboard (paper on the other side), which is still held together by the two halves. Everything, the work is done, you can think that you have coped with this work.

Such a cut is needed if there are any obstacles during the construction of the structure, for example, you need to cut a letter under a window, door, etc. To do this, at home, you need to cut a square or rectangle on one side. It will not be difficult for you to do this.

On the one hand, we cut it with a hacksaw, on the other, we cut the cardboard, as we described above. And everything is ready. It remains only to process the edge with a plane.

How to cut round holes

Almost always, these types of holes are used for cutouts for an outlet, chandeliers in the ceiling, lamps, and more. There are two options for doing this. The first is to take a special nozzle with which holes are made for the lock in the door. Such a nozzle is pushed onto a drill, and after that a hole is cut.

With the second option, you will not need a drill, but just a hammer and a cut out circle of the desired size. You need to attach this circle and gently hit with a hammer. Of course, the effect will be worse than with the nozzle, but it can also be quite amiss.

This type of cut is usually used in toilets or shower rooms, since there are a large number of pipes and other plumbing units. The biggest problem is calculating the dimensions of the cutouts. First, it is advisable to check the contour several times on which the cutout will be applied.

If it is more than necessary, then there will be many problems with fastening the letter to the frame. If not fit enough, it will take your time to fit.

Next, you need to make a plan of your actions. Take a few more looks at your resulting drawing. Usually, in many cases, all curvature flaws are a hybrid of straight lines and a semicircle. For straight and semicircular you have your own tools. In those areas where you definitely intended to make a cut, use a hacksaw, and all uneven bends and roundness are cut out thanks to the knife.

That’s all, now you know how to cut drywall at home. There is really nothing complicated about it. Everyone knows that only with practice can experience come.
