Cutting tiles under 45 degrees: how to do it best?

Technology of cutting tiles under 45 degrees allows you to aesthetically cover any outside corner when finishing walls with ceramic finishing materials. In doing so, it eliminates the need for the purchase and subsequent use of special decorative corners, whose appearance can adversely affect the overall design of the room. Plastic and metal corners are not only unaesthetic and unfashionable, but also not practical. Given this fact, it is worthwhile to understand how the cutting of tiles at 45 degrees is carried out and what recommendations should be observed in this case.

The technology of cutting the ends at 45 degrees eliminates the need to use decorative corners in finishing exterior corners. Thanks to this it will be possible to create an aesthetic appearance of the wall. These corners have a neater and more stylish appearance than those finished with corners. Agree, it’s a lot more interesting than overlapping tile on tile or inserted plastic.

Measuring and trimming the tiles

Finishing the second row of wall tiles, I’m coming to the niche with the radiator. And here I will first have to measure and cut the tiles, and then make a barb. I lay the tile and install spacing crosses, pre-marking the place where the trim will go. I will tightly tape the place of the future cut to protect the future tiles from chips. Of course, there is an option to first cut the tiles to the width on the tile cutter, but I will cut and process the edges of the tiles immediately with an angle grinder. I reattached the tile with the tape already attached and marked the cut, adding the thickness of the tile and the adhesive gap. that way I immediately account for the thickness of the tile glued into the niche end. Now I will run the line for the trimmer on the scotch tape on the previously made mark. In this case, the tape protects the tile from chipping the enamel when cutting. For trimming and deburring, I’ll be using a small angle grinder. Notice the disc that’s mounted here. This is a stone and concrete disc with notches on the cutting part. There is also a disk with a solid cutting part, it does not have any notches and is designed for cutting stone and tiles when cooled with water. You can’t use a disc like this to cut tiles with an angle grinder, but you can use it to try and deburr the tiles. A lot depends on the quality of manufacture of these discs. Don’t be lazy to look for options in a construction store. Be sure to use safety glasses and gloves when working with the angle grinder. I will start by cutting the tiles with the angle grinder along the intended line. This operation should be done slowly and carefully not to overstep the line. This cut is made at a right angle to the tile. After removing the excess, we’ll lightly sand the edge.

And now I will make a contouring on this edge, that is filing at 45 degrees. Of course, it takes some skill to do this job, but it’s easy to train, and here are the basic features:

  • The blade of the angle grinder is at a 45 degree angle to the tile at all times.
  • Moving the disc across the tile, remove a small portion of the edge. Perform the up and down movement smoothly.
  • Try not to touch the glazed edge of the tile. Leave about 1 millimeter to the edge. That way you avoid unnecessary chips.

When the rough trimming is done with the angle grinder, you can remove the tape. Let’s look at the edge of the tile. As you can see, it’s filed at a 45 degree angle. And now we’re going to bring this filing to perfection. I do this with this simple device. This is a medium sized emery cloth and a small block. The bar is placed on the burr, and now the final sanding is performed along the filed edge. The bar allows me to keep track of the grind angle. It should also be 45 degrees. The movement should be light. Visually, I keep control of the back glazed edge and try not to hit it. After I finish sanding, I check the quality of the trimming, and if necessary, I’ll do it again. And you can check the quality of the backsplash by sanding two backsplashed tiles together. At the resulting joint will be immediately visible errors. They should be eliminated, especially if you plan to join the tiles using the seamless method. In my example, I used a simple grouting of the tiles in the niche using a seam. The joint at the junction of the two tiles I chose the size of the distance cross, which is used for this wall tile. Sometimes sanding a tile at 45 degrees is a good option for its junction with a window opening. And then such a joint will look like this beautiful. I would like to point out that an alternative to manual boring with an angle grinder is the use of a wet cutting machine with adjustable position of the tiles.

Cutting the tiles at 45 degrees will allow you to make a nice outside corner without using a plastic corner. And this means that there’s no need to go shopping and choose a plastic insertion for the tone of the tile. Smooth corners tiled look aesthetically pleasing, and most importantly, new. Agree, this is much more interesting than overlapping tile on tile or pasted plastic.

How to properly trim a tile at 45 degrees?

In order for the corner of the two tiles to look beautifully, when trimming the tile you need to reach the glaze a little bit (0.5-1mm). That is, only the clay is cut. If you go over the glaze (the front of the tile), it will be “ripped” and scratchy. It would immediately catch the eye, it’s not pretty.

This is the problem we encountered when trimming wavy tile. But about that later.

Sure many of you have seen such “art”, but most often everyone thinks that it should be like this. And a tiler with twenty years of experience assures that it can’t be any other way.

Even if there is a need to trim the corner of the tile not from the “factory” edge and you have to cut the glaze, there is still a way to do it beautifully.

First, to do this, you must first cut the tile evenly (to the right size), and then already, again, not reaching the glaze, trim it at 45°. This cut will be much cleaner and prettier.

It is also possible to treat the edge of the glaze with a fine emery, from this it will be even smoother.

Secondly, you can still cut the corner from the beautiful edge (the factory end), and trim the opposite edge with sandpaper and hide it in the other side. This will be less conspicuous.

So, for example, we once did when tiling the toilet installation. Because a nice corner is more important than the bottom seam. Especially since it turned out to be very neat, too, and if you don’t know that it’s trimmed, you’ll never pay attention to it.

What is it for??

Cutting tiles at 45 degrees may be necessary in two cases:

  • When, for example, a diagonal layout is implemented. Accordingly, the products themselves will have to be cut diagonally, at 45 degrees.
  • When the outside or inside corner is docked. And the bevel is needed for the edge to form a nice and even corner, without plastic and other corners.

Since the goals are determined, you can move on to the basis. what to cut tiles under 45 degrees.

How to cut porcelain tile and ceramic

Let’s look at the basic and most effective ways to cut porcelain tile and ceramic tile.

Glass cutter and tile cutter

The properties of porcelain stoneware differ from those of ceramic tiles, it is more durable and the glass cutter is not very suitable for cutting such material. Therefore, this hand tool should be used on a simple tile for home use. The tile cutter, using a cutting roller and a pressing force, copes with this task quite well. When working with a glass cutter, use a flat surface, a guide (it can be a metal ruler or an angle) and a thin blade, because a thicker diamond blade can leave an uneven cut. With a forward and slow movement, press the surface of the cutting wheel on the face of the tile (you can do it a few times, for better effect), then put a big nail or a wooden bar under the bottom of the tile, exactly on the cut line, and with a light pressure of your palms split it into two pieces.

It should be understood that the glass cutter does not make a straight and sharp cut, because you need to apply equal pressure on the entire surface of the tile, which is difficult to do by hand. You should also take into account the heterogeneity of the inner structure, which complicates the processing of the material, which leads to chipping at the point of cut. In any case, all the disadvantages of cutting ceramic tiles with the glass cutter can be compensated by sanding the edges with sandpaper by hand or by using sanding accessories for power tools.

The tile cutter will be an excellent method if you need to cut a small amount of ceramic tile. Tile cutter, a little simplifies the work, but it works on the same principle as the glass cutter. The undoubted advantage of the first is its automation, because you do not need to manually align the course of the blade, and the process itself is accelerated and becomes more automated. This is an economical, but slow and requires a good knack for processing ceramic tiles. Suitable for small budget repair.

Angle grinder (angle grinder)

How to cut porcelain tiles and ceramic tiles with a corner grinder? First, you need the tool itself, namely, angle grinder (angle grinder), and secondly, use a special attachment for cutting tiles (it will greatly simplify the process of cutting and secure the work), and thirdly, buy some good cutting discs for angle grinder, because porcelain tiles and ceramics. is a durable material. During work, the discs heat up to high temperatures, so they quickly fail and can burst, which is fraught with injury. In addition, protect your hands, eyes and respiratory tract. After all, tiles can give a chip, and in the process of cutting a large amount of dust is released, which is best leveled by regular dousing of the processed material with running water. Such a process is used on professional tile processing machines.

Ceramic hacksaw (blade)

Hand and power hacksaw with ceramic saw. As any manual work requires special accuracy at work. Draw a level cut trimmer line on the surface of the tile, then saw it evenly lengthwise. Manual cutting of ceramics is not much different from cutting wood, the only difference is the cutting speed, because when friction between metal and ceramics produces high temperature and the saw blade can break, so there is no need to hurry when such an operation, to saw carefully and extremely accurately. Consumables in this method wear out quickly, so it is better to use this method for single items.

Electric tile cutting machine

Choosing how to cut porcelain tile and ceramic, you must take into account, the machine is still the fastest, most productive and accurate method of processing this material. They also make it possible to cut very specialized types of tile, such as curved and hole cutting, 45-degree cuts, and more.п.

Pliers for tiles

For the shape cut, you need pliers. Actually, they don’t cut tiles, but break off small pieces from them. Because of this, trimmer lines turn out uneven and require additional sanding.

Tile cutters are invented to make material for mosaics. For ordinary repairs, they began to be used later. Pliers in general are similar to conventional pliers, only on the bottom they have a diamond roller, and on top of the so-called “jaws”.

To get a circular notch, a marking is made, and then small pieces are selected. If it is necessary to make a straight cut, then first a cut is made along the glaze with a roller. Then the roller is put under the bottom, and the jaws on top. When you press the handles, the tile breaks along the line.

Also, pliers are very useful if you need to cut a trimmer line of less than 5 mm from the tile. Other tools can not cope with such a task. It’s better to use a spirit level, so that the laying won’t go askew along the wall.

How to cut tiles with a tile cutter

There are hundreds of models of tile cutters, which can all be divided into two main groups: manual and electric.

  • Hand-held tile cutters are available in the form of pliers, which resemble pliers. With the help of this tool, first on the front side of the tile covered with enamel, a neat cut is made with a diamond cutter. After that, using the angle of the tile cutter, the tiles are simply broken. No special skills are required, so the tool is suitable for amateur beginners.
  • Desktop models of handheld tile cutters that have different base lengths are used for cutting tiles with a thickness of no more than 15 mm. For example, cutting 8 mm thick tiles used for wall cladding is done with a tile cutter that is no more than 400 mm long. Some models, equipped with a circular cutter, are able to perform rounded holes with a diameter of up to 80 mm in addition to straight cuts.

Important! Choosing a handheld tile cutter, pay attention to the way its cutter holder moves on guides. It is better to give preference to the tools, which are equipped with self-lubricating sealing rings or bearings.

  • Electric tile cutters are used when tiling on a large scale. This power tool is indispensable when cutting thick tiles. Choosing a tile cutting machine, look at its power, the size of the diameter of the cutting wheel, depth and length of the cut, table size, tile weight. It also matters the time during which the machine can operate continuously.
  • Electric tile cutters are divided into two types, which differ from each other by the way the motor is located. Models with a bottom-mounted motor are compact, so they are used when working in small rooms. The upper location of the motor is used in the design of rail-mounted tile cutters, which are much more convenient in operation. In addition, the quality of their tile cutting is much higher. The diamond disc in all tile cutters is water-cooled. An advantage of electric tile cutters is their ability to cut ceramic tile at an angle that does not exceed 45 degrees.

Important! Choosing an electric tile cutter, pay attention to both the manufacturer and the technical characteristics of the tool. A good tile cutter has a rigid base and thick-walled guides.

The disadvantages of a corner on a tile sharpened at 45 degrees :

The angle becomes more vulnerable to impact. Especially if it is on the aisle. It’s enough to hook the slope with an empty metal bucket so that a piece of the drained corner on the tile flew away. The work becomes more time-consuming, and thus also the price.

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

Opinion of masters about cutting a tile on the angle at 45 degrees.

You can also prepare a 45 degree angle on the tile with an angle grinder. A lot of dust. Wrong quality. But really. The main thing is cheap and always possible.

It is especially important to mark the correct corner when laying decorative stones. Often the corner elements for such products are not provided or not available. Cutting stone at a 45-degree angle is the only way to get out of a situation like this.
