How to cut porcelain stoneware at 45 degrees

Guide to bending a metal angle

Sometimes it is necessary to undercut this or that detail or product at a certain angle. As a rule, you need to trim baguettes, moldings, casings, baseboards and other similar interior elements at an angle of 45 degrees. Anyone can cope with this task. The main thing is not to hurry, do not be nervous, and everything will work out.

Buy ready-made corner elements

Of course, the easiest thing is not to bother with trimming a part, and buy it already ready, which does not need to be processed and trimmed. Such details and elements are sold today everywhere in large supermarkets or smaller stores.

For example, with regard to the baguettes or fillets, then they are sold special corner elements that fit perfectly into the corner and do not need to be trimmed. They just need to be glued in place and pressed down well.

The way to connect the trimmer without trimming

Roof architraves today often do not trim at an angle to dock with each other, and make the junction at right angles. This method of connecting the platbands does not require any special trimming, which is very convenient. In addition, this method looks more modern and attractive.

Trimming at an angle with a wire cutter

If it is still necessary to undercut at an angle this or that part, then it is worth stocking the jig. the simplest device, which in appearance resembles a small box. The chair has slots that are designed for a saw or a long sharp knife. Of course, these cuts are made so that they form an even and accurate angle of 45 degrees.

However, the cross-cutter can have a lot of cuts at once, at different angles. It’s convenient because with one device, you can cut any part at different angles.

Chisels that can be adjustable are also for sale. The slots in such a saw can be adjusted, which allows the craftsman to set exactly the angle that is required at the moment. In particular, it is quite easy to translate the slots of such a jig to a position of 45 degrees.

Now the workpiece can be trimmed elementary. Put a molding, a platband, or a baseboard into the jig, and then insert the saw into the slots, and simply cut off the excess material. The angle turns out as a result ideal, exactly 45 degrees.

What to do if there is no jigsaw?? Very simple. It is necessary to make a template, on which it will not be difficult to transfer to the workpieces the necessary markings. You can choose thick cardboard or something else, that will be appropriate in this case, as a template.

Using sandpaper

This material most often comes to the rescue, to hide the inaccuracies of the preliminary work, when the glaze is damaged or chipped. In addition, there is another option for the use of sandpaper.

Instead of professional tools and the need to preserve the glaze layer, an incision is made on the face with a glass cutter. After that, on the back side an angle grinder notch in the form of a letter “V” is made, which must be made across the entire width of the tile. All that remains is to break the element, and the remaining work is completed with sandpaper.

Some craftsmen try to reduce the cost of the work, using only ordinary sandpaper. In this case, filing the corners of the tiles under 45 degrees is done independently, watching the condition of the clay and the glaze itself. If you overdo it, the damage will affect the tiles, therefore, you will have to spend money to buy a similar material. Significant importance will play and the coarseness of the sandpaper itself, which should vary.

For precise alignment, two versions of the material to create a bevel of 45 degrees will do:

The first numbers will be used as a rough tile trim, and the second to create a really smooth and high-quality surface as much as possible. Only after that you can put the tiles on the corner without fear of criticism from the outside. If you follow the requirements and recommendations from experts when making 45-degree filings, there will be no questions about how to design tile corners. In the end, you can even say that you got a tile without corners.

What tools are used to sharpen the ends of tiles under 45 degrees?

Cutting porcelain tile under 45 degrees can often be referred to as filing, sharpening, trimming, barking. In this case the meaning is the same in each case. The end of the tile is grinded so that it changed its right angle to an angle of 45 degrees.

Such an operation can be performed using different tools. But the best result and the highest quality of sharpening the ends is achieved with an electric tile cutter, which is a special device for cutting and sharpening the ends of tiles. In extreme cases it is allowed to use an angle grinder with a special wheel for cutting tiles. However, in this case, the master must have sufficient experience and skills to do the job qualitatively.

In any case it is worth getting acquainted with each method of cutting tiles and porcelain tiles under 45 degrees.

Cutting tiles with an angle grinder

Cutting tiles at 45 with an angle grinder is quite time consuming and technically complex process. Not every experienced craftsman can accurately trim the end face of the finishing material. True, with the proper skill and experience with this can still cope. In fact, the use of an angle grinder is the most affordable way to trim tiles at home since many people have such a tool at home, which cannot be said about electric devices for sharpening or cutting ceramic finishing materials.

Before you start using an angle grinder, make sure you have a good diamond disc that is suitable for cutting ceramic tile and porcelain tile.

Diamond spraying on the edge is essential

The ceramic tile is put on an edge, and then the other edge, which is in a perpendicular position, is accurately roughened with a diamond wheel to an angle of 45 degrees. In this case it is worth remembering that the back, not glossy side of the tile should be undermined.

If the surface is not perfectly flat the first time, it can be smoothed by going over it again with a diamond wheel. A belt sander can also be suitable for this purpose. But it is true that not everybody has such a tool at home. Therefore, as an alternative, you can offer to use a wooden bar, wrapped with sandpaper.

You can also use sanding discs with velcro. Such nozzles simply screw on an angle grinder, and then glue sandpaper to them. You can use diamond nozzles, characterized by a long service life and higher performance. True, they cost considerably more than regular Velcro sandpaper.

When finishing large areas, it makes sense to spend money on the purchase of diamond tips. If we are talking about finishing a small area of the wall, such as the apron in the kitchen, you can be limited to the use of abrasive circles.

Electric tile cutter

Can also be installed without legs

A tile cutter is a machine for cutting tiles at 45 degrees, as well as for cutting them longitudinally and transversely. Such a device has a water cooling system. In addition, water helps to remove almost all the dust that occurs during the cutting of porcelain tile or ceramic tile. The main advantage of the tile cutter is its accuracy. It cuts along a single, pre-set trajectory. It allows to exclude influence of such factors, as shaking of hands of the master. As a result, the cut is as even and accurate as possible.

Tile cutters can cut at virtually any angle. However, often masters cut the tile at an angle of 90 degrees or 45 degrees.

How to achieve a perfectly straight angle at the joint?

If you want to create a level joint, you have to work as carefully as possible:

  • First, the first tile is attached using a construction level. Its edge should slightly extend beyond the plane of the corner of the base.
  • After that the second side of the corner is aligned. Each tile adhesive has its own curing time, that’s how long you are given to trim the resulting angle.
  • Using the same principle, subsequent fragments of tile are glued. The main thing is that the verticality of the walls initially was sustained, otherwise it will be almost impossible to hide the defect from the bad joints.

Keep in mind that tile becomes more brittle at the joints after undercutting. For this reason, this laying is not usually used on surfaces that are subject to high impact loads. It is especially rarely used when tiling steps. For example, when decorating outdoor stairs builders often use metal corners, and sometimes lay overlapping tiles so that the top module is slightly protruding over the side.

If you want to make the trimming of the ceramic fragment with your own hands in a simpler way, there is another option. To do this, draw a line on the decorative side of the tile with the glass cutter. After that, turn it over with the wrong side facing you, and then make a V-shaped cut to the full width of the tile with an angle grinder. Now you can break off the excess material, and also finish it off with an emery cloth.

Using a tile cutter

To learn how to work properly with this tool, you need to follow a certain order of action:

Apply painter’s tape to the tile in the place of the cut. Mark the desired width of the trim on the tile using a pencil and ruler. Position it on the platform of the tool. Press the tile down and gently push it against the disk. First you need to saw off the excess, and then engage in sanding the corner. It is necessary to avoid touching the glaze, otherwise the edges will look uneven

If the superficial decorative layer of the tile is still damaged, with enough skill it can be sanded down with an emery machine.

How the corners of drywall constructions are decorated

Exterior Corners

Gluing the aluminum exterior corner to the Fugenfüller compound.

Finish the corners of drywall using the following auxiliary corners:

  • aluminum, it is quite rigid, it is not subject to the process of rusting, it can be used if you need to seal the corners of drywall at right angles;
  • galvanized, it is more rigid, it is difficult to break, but it can rust over time, also used for straight corners;
  • of plastic, this element is less rigid, does not rust and is not brittle, can be used for all corners, for acute, straight and unfolded.

Treat the corners of drywall by gluing a plastic corner on the unfolded corner.

The question arises, but how to seal the corners of drywall with corners? You can watch a video about this process on our website.

The principle of working with all types of corners is the same:

  • Remove the chamfer from the end edges with a special planer to work with gypsum board, so there would be no protrusions;
  • we put a layer of gypsum filler on both surfaces, the best way is to use Knauf Fugenfüller;
  • We glue the corners, pressing them with a rule or an even lath so that the surplus of the mixture came out through the peoria;
  • give the corners a chance to cure putty with a thin layer of Fugenfüller.

Interior corners

Internal corners at the joints of Knauf sheets are sealed with a paper reinforcing tape and leveling putty.

Tips from the experts

To work with porcelain tile, it is preferable to use a professional electric tile cutter, as it is adapted to work with a harder material. And this material itself costs more, so you want to minimize its loss during processing.

When filing, the angle can be done not at 45 degrees, but sharper. This will somewhat simplify the gluing of tiles at right angles.

When working with bevels in the corners of high-quality grout is very important, because catching a tile with a gap can even be a belt from clothes. This can lead to the splintering of its fragment. If the chips still occurred, but at this point you are not going to replace this tile, grout will help hide the defect. They come in different colors, so it is easy to match the color of the ceramics. There is also another option: to use any available grout and touch it up with paint of the desired shade.

When after laying tiles at the seams visible minor flaws, such as from the failed grinding of the glaze, you can use masking compounds that will hide the imperfections. Such remedies are convenient to use. in the cap, as a rule, there is a small brush. The main thing is to carefully study the instructions. Note that we are talking about very minor flaws, and not about chipped pieces of ceramics. Correcting agent will be an indispensable assistant, if you need to “discolor” a small crack on the tiles, and on any ceramic product.

With sufficient experience with finishing materials, you can do everything yourself. If you do not have the necessary skills, but finances allow hiring experienced workers, then it is better to trust the professionals. then the quality of work can be no doubt.

What to cut tiles at a 45 degree angle

Electric tile cutter

Electric tile cutter. this is an expensive, but necessary tool for a large amount of tile cutting. Makes a straight cut and bends at a selected angle. Can be set from 0 to 45. In practice, most often the tiles are cut at 45 degrees. Quality models are equipped with cooling system. This prevents the tile and the tool from overheating and reduces dust in the workplace. Water supply does not affect the quality of cutting.

Consider purchasing an electric tool if you need to trim hard and expensive material. porcelain tile. The most popular are the following models:

porcelain, stoneware, degrees
  • Zubr EP-200-1000S (Russia). stationary floor tile cutter. The machine is expensive (21-22 thousand), is designed for professionals and allows you to cut tiles of any thickness.
  • Zubr EP-180-600N (Russia). compact table model. It is used to make straight cuts and barking tiles at an angle of 0 to 45 degrees. Low noise and dust-free: water flows to the cutting point. affordable price (4000 ) can be attractive for beginners.
  • The Feida TC 200 and Feida TC 250 (China) help you accurately chamfer the high quality at an angle from 0 to 45 degrees.
  • Machine tool for cutting tiles Einhell TH-TC 618 (China). allows you to saw and make a trimming of various ceramics, provided that the kerf depth will not exceed 22 mm.

If you cut a tile a little less than 45 degrees, it will be easier to form a right angle.

angle grinder

To work in one apartment to buy an electric tile cutter is not rational. You can qualitatively cut ceramic tiles at an angle of 45 degrees with an angle grinder (angle grinder). It is easier and faster to perform the work with a diamond disc. The edge is likely to be jagged. Such defects are grinded with turtles. If the amount of work. one apartment, you can instead use a cheaper option: the replacement sanding discs on velcro.

  • BIZON 0512003, thickness 1.8 mm;
  • Union 9020-04-150x22K, h= 2 mm;
  • Expert (180×25.4/22.2 mm) PRACTIKA 034-793 (for ceramic granite);
  • Professional KEOS DBP01.200 on porcelain stoneware (180×25.4/22.2).

The quality of work depends on the type of nozzle on the angle grinder for the final stage of cutting at 45 degrees. The diamond wheel (flexible, grinding) AGSHK 100 0 “Turtle” provides a good result.

angle grinder for filing

An ordinary angle grinder is in the arsenal, not only among professional finishers, but also among amateurs. It must be equipped with a diamond disc. Place the tile under the ridge face down. The tool should have adjustable speed, then achieve the desired angle will be easier. In this case, you need to set the minimum to begin with, so as not to melt the edges. When the proper angle is grinded, go over it again with a diamond wheel to grind it. You can use a file or emery paper to grind.

There are also special attachments for grinding. They are easy to replace. the base with Velcro is installed on the threads of the angle grinder. They are not as durable as diamond “turtles”, but they cost less. For those who are not engaged in repair on a production scale, this may be quite enough.

Many people prefer to use a mask or respirator when working with an angle grinder. This tool generates too much dust, which is not recommended to breathe.

How to use an angle grinder?

Consider in more detail how to use an angle grinder, working with tiles:

  • The tile should stand vertically in the vice. Place the diamond disc, and then choose a working mode of 1000-2000 rpm.
  • Remove the corner with a part of the disk, on which the notches are applied.
  • The tool should be placed at an angle of 45 degrees (relative to the front plane of the tile).
  • Remove the excess with gentle strokes, so that each time a thin layer is removed from the surface, not reaching the edge of the outside corner.
  • The edge thickness (about 2 mm) should remain intact. You can mark this distance with a pencil.

In the second step, a support plate is mounted on the angle grinder. A wheel with sandpaper is placed in the center of the backing pad. Now you can finish the edge, and then create as sharp a corner as possible.

How to avoid chipping

chips are the most undesirable result when boring tiles. You can not close your eyes to them, as negative consequences are possible:

  • The service life of the coating is reduced;
  • the corners of the jagged edges cling to everything,
  • The tile is quickly destroyed;
  • complicated surface care because of the sharp edges.

To perform the work without chipping will help the recommendations of the masters:

  • the tile is cut only from the back side, the distance to the glaze is left 0,5-1 mm;
  • a new disc with a diamond coating is taken for the angle grinder;
  • the work must be performed slowly.

How to avoid chipping

Chips are the most undesirable result when tiles are notched. You cannot close your eyes to them, as negative consequences are possible:

  • The life of the coating is shortened;
  • everything clings to the corners of the jagged edges,
  • The tiles are quickly destroyed;
  • sharp edges make it difficult to clean the surface.

To perform the work without chipping will help the recommendations of the masters:

  • tile is cut only from the underside, to the glaze left a distance of 0.5-1 mm;
  • A new diamond-coated disc is taken for the angle grinder;
  • the work should be carried out slowly.


To make a high-quality and even cut without chips and cracks is possible only with the help of special devices, each of which has its own advantages.

The electric grinder

The main advantage of this tile cutter is the clear and qualitative cut on tiles, which is done in two directions: the ordinary straight cut and the special 45-degree angle cut. Thanks to the angle of the cutting wheel, it is easy to make cuts starting from 0 up to 45 degrees, depending on the part of the tile to be cut. The electric machine can have a water feed function, which produces less dust, or it can have a conventional design. However, both versions of the devices provide the same quality of work and guarantee the cutting of a large volume of tiles in a short period of time.

In the case of cutting concave tiles, the electric tile cutter does not follow the concave deflection of the product. That’s why only the back side can be cut, so as not to damage the enamel on the front. This is especially true for porcelain tiles.

  • A special painting tape;
  • a simple pencil;
  • A small ruler;
  • tile cutter machine;
  • Angle grinder with adjustable speed revolutions.

On the part of the tile, where the cut will take place, you need to glue a masking tape. Use a pencil and ruler to make the necessary markings. Then place the tile on a certain section of the device at a 45-degree angle. On the principle of a circular saw with a diamond band, the tiles are cut. In some models, water is supplied during the cut, which protects the tile from melting and washes away the dust.

If the glaze on the outside of the tile is damaged, the cut will be ugly with cracks and scored edges, which when laid side by side will have a sloppy appearance. Therefore, when working with an electric tile cutter, you need to carefully remove only the clay layer.

Professional secrets of experienced tilers:

  • With a tile cutter it is necessary to achieve an even cut;
  • Then form the necessary angle on the back side of the product;
  • The glaze, which was caught in the working process, is grinded with sandpaper.

Manual tile cutter

Manual tile cutter is popular not only among professional tilers, but also among amateurs. Many models of such tile cutters are equipped with a special rotating base and a built-in ruler, which allows making a high-quality cut of the tile under 45 degrees. After inserting the tile into the tile cutter at a certain degree, you must align the mark on the tile and the building tool. Putting the handle down, you need to move it slowly with equal speed and even pressure in the direction from yourself.

angle grinder

Despite the fact that such a construction device is present in almost every home, it is very difficult to make a cut of tiles under a 45-degree angle with an angle grinder.

For fast and even tile cutting, it is necessary to install a diamond wheel on the device. Place the tile under the rib, with the outer side facing downwards. Now with an angle grinder you need to grind at a 45-degree angle the back side of the ceramic tile.

From the first time to make an even and clean cut is not possible. Therefore, after the corner is formed, it is necessary to repeat the process and go through the diamond wheel angle grinder on the cut edge. Only in this way the corner will become even.

To form a corner on the tile, it is necessary to choose the right angle grinder, because not all models can perform the necessary functions. In this case, it is worth buying a construction tool, which can adjust the speed.

At the beginning of work, you should set the minimum speed at which the edges of the tile will be sanded and not burned.

Disadvantages of the angle on the tile, sharpened at 45 degrees :

The angle becomes more vulnerable to impact. Especially if it is on a pass. It is enough, to hook the slope with an empty metal bucket, so that a piece of the drained corner on the tile, flew off. The work becomes more time-consuming and therefore also more expensive.

Catch such a corner can be anything, even a harmless belt buckle of a trouser belt:

Opinion of masters about cutting tiles at an angle of 45 degrees.

To prepare a 45-degree angle on the tile is also possible with the help of an angle grinder. A lot of dust. Not the same quality. But really. The main thing is that it is cheap and always possible.

It is especially important to mark the correct angle when laying decorative stone. Corner elements for such products are often not anticipated or are not available. Cutting a stone at an angle of 45 degrees is the only way out of this situation.

Ways to cut the trim under 45 degrees without resorting to the use of a plier

The easiest way is to use an ordinary protractor, which is in every home where a school-age child lives. It is not so difficult to make a marking with it.

Important: The cut is also important. To avoid the formation of gaps, it is recommended to use a hacksaw for metal, not for wood. Yes, this method requires more time, but for that the cut will be much more accurate and even.

When you made the marking using protractor you must put the platband on the horizontal surface so that the angle is at the top. It is recommended to make the cut along the whole plane of the architrave.

If you do not have any stationery, you can use an ordinary tile to make a 90-degree angle. Dividing it into two halves, we get a template for a 45-degree angle, which can be used for marking instead of the chisel.

If you have a ruler, the task becomes several times easier. You just need to take a sheet of A4 and draw a square, and then draw the bisectors of the angles. To make it more convenient, you can take a small plank and attach it to one of the corners, which will fix the construction. And then you need to attach the platband and start sawing.

How to Make a Jigsaw at Home?

If the above methods are not to your liking. you can make a chisel at home yourself. A chisel is a U-shaped device, reminding of a tray.

It is equipped with saw slots, designed for sawing the material at a certain angle. The size of the parts is not very important, but the wider will be our homemade device, the wider and more accurate we will be able to saw wide bars.

Important: You must do everything wisely, do not overdo it, because if the width of the chisel will exceed half the width of the hacksaw, it will be uncomfortable to cut.

You can make a marking resorting to the methods described above, and then use small pieces of plywood and a hacksaw. And in order to fix everything you can use self-tapping screws or even super glue. However, this is more complicated and takes a lot more time, although it will give the most accurate result (if done correctly, of course).

Undoubtedly, the crossbeam is a convenient and practical tool. It is sold in almost any construction store and has a low price, which can pull absolutely everyone.

However, if by some reasons it is impossible to get the tool on short notice. you can use improvised tools, such as ruler, protractor or even tiles, which can easily create a template with the necessary markings or even recreate the jib at home.
