When installing skirting boards, it is important to correctly form the corners. They often spoil the big picture. How to make a corner on the baseboard. external and internal, how and with what to cut. We will discuss all this further.
Types of indoor corners
When installing skirting boards, you need to somehow draw the corners. In appearance, the angles are external (which protrude forward) and internal (for example, the angles in a room). In rooms with normal geometry, the angles are right, i.e. 90 °. When joining two pieces of plinth in the corner, they are cut so that each has an angle of 45 °.
To make the outer and inner corner, the baseboard must be cut
But how to make a corner on the baseboard so that it is exactly forty-five degrees? To do this, use a special carpentry tool. a miter box.
Skirting miter box
A carpenter’s miter box is a device for cutting at a certain angle. It is used with a hacksaw. In principle, you can make the miter box yourself by collecting the guide from the boards and making cuts in the walls. On sale there are various models costing from 15 to several hundred dollars. They differ in capabilities, materials, although all are called "miter box". Professional models are made on the basis of a good hacksaw, have a scale that allows you to set the saw as it should. With such a tool, it is not a problem to set any desired cutting angle in order to properly cut the skirting board for a perfect fit.
Professional Carpentry Miter Box. Wide Range Tool
The simplest miter box is a plastic U-shaped profile, in the walls of which cuts are formed. These slots are used as a guide for a hacksaw. They do not allow the canvas to deviate. In any case, there are two cuts. straight and at 45 degrees. Some may have a couple more options.

Sometimes a hacksaw is included, sometimes not. Usually the ones in the kit are not too good. Any hacksaw can be used by selecting a blade for the material to be cut. It is important that the canvas moves freely in the slots.
How to cut a skirting board in the inner corners: an action plan in steps
Start installing skirting boards in one of the corners. If this is the first experience for you, choose the part of the room in which something will stand. Not always, it’s over, the first pancake is lumpy, but it’s better to play it safe. To make the corner on the baseboard neat, work without rushing. One sawed off, checked, fitted. We pass to the following. It is better to fasten after two adjacent corners are assembled. But you shouldn’t postpone the assembly too.
Trimming the baseboard in the corners requires certain skills. But having made several joints yourself, you can beautifully design complex corners
How to use a miter box to cut skirting boards? Place the device in front of you, preferably on a table, but you can also on the floor. Which side it does not matter to turn, it is symmetrical. In the profile, insert the bar, rotate it as it will stand against the wall. When washing a floor plinth in a miter box, the “wall” is that wall that is farther from you. Once again: firmly press the baseboard into the back wall in the position in which it will be installed. Insert the hacksaw into the required slots. You can start sawing.
First joint in the room
The first plinth trim must be cut as close to the edge as possible. Carpenters have their own jargon and they say “slaughter” a corner. No matter what you call it, it’s important that in the miter box we set the bar so as to make a cut at the very beginning. For the cut line we push the bar a short distance, for starters it can be 1-2 cm. Cutting a smaller piece is more difficult, so leave the savings “for later” when at least some skill appears.
In the miter box, the plinth is placed at the far wall "facing" to ourselves. So it’s easier to check whether you are cutting / sawing correctly
Next, make the corner on the baseboard as follows:
- We lay the baseboard in the miter box, press it against the wall opposite to us. We expose it in the mounting position. how it will stand against the wall.
- Insert the hacksaw into the desired slots (see the figure below).
- We move the bar so that it slightly extends beyond the cut line.
- Cut off.
- We take the second piece of the plinth, repeat the same operations, but we change the position of the saw on the miter to the opposite. We insert the bar on the other side. Be careful here, otherwise you will have to redo it several times, since the connection will not work.
How to cut the floor skirting board in the miter box: for the external and internal joints
We got two pieces sawn for docking in the inner corner. To make the joint perfect, try on the details in place. Most likely, there are some flaws. We take sandpaper with medium grain, remove everything that interferes with docking. Then, with fine grain, we achieve a tight connection without cracks and gaps.
When connecting baseboards in the corner, use transparent silicone sealant. Before installing the fasteners, a layer of silicone is applied to the slice. Immediately after the baseboard is fixed, remove the excess that has appeared on the outside. We remove to an absolutely clean surface. This method of joining skirting boards in the corners looks more neat, it does not clog dirt and dust.
How to cut the corner of the baseboard at the right distance
The second and all other corners of the skirting boards must be done at a certain distance. If the next angle is again internal and the distance to it is less than the length of the bar, we use the same fragment that already has a gash. We measure the distance with a tape measure. strictly from corner to corner. Then this distance is laid on the bar using the same tape measure. The beginning of the measuring tape is combined with the protrusion, we measure the required distance, make a mark with a pencil. She will be the starting point for the cut.

The skirting board with a mark is laid in the miter box, the desired direction of washing is chosen. The dash can be combined with a hacksaw blade or with a slot in the miter box. To whom it is convenient. Cut off. This segment must be "tried on" in place. If both corners rest against opposite walls or the gap is only 1 mm, then everything is fine. You can cut the second bar from a new piece for the design of the joint. And again, remove the flaws with sandpaper.
If the wall length is longer than the length of the plinth plank, take a new plank. We’ll slaughter the second corner on it. It is important not to make a mistake in which direction to cut. By setting both planks along the wall, mark the connection point on one of them and make a direct cut. For a direct cut in the miter box, there are also slots. So there will be no problems.
How to connect two skirting boards on a straight line
But the joint in a straight line does not always look perfect, and during operation it often diverges, forming a visible gap. If you want, you can cut at an angle (any) two levels.
To do this, first cut off the edge of one bar at an angle, mark the second connection point. A mark is placed on the side of the baseboard that is pressed against the wall. At this point, we saw off another section, without changing the position of the saw relative to the miter box, but inserting the bar on the other side. The joint is obtained obliquely. He is more accurate. Especially the difference is visible on wooden skirting boards and MDF. The slice, again, is brought to mind using sandpaper.
We make an external joint
In apartments or houses there are not only internal corners, but also external ones. In this case, first cut the nearest inner corner, modify it. When it is ready, you can make the outer corner on the baseboard. We put the bar in the corner, as it should be. In the place of the outer corner with a pencil, make a mark exactly at the place of rotation.
How to make the outer corner of the skirting board
Then we transfer the bar to the miter box, select the appropriate position. In order not to make a mistake, always imagine how the baseboard is standing against the wall and what you should be able to do.
Saw the second segment at 45 degrees so that it docked with the finished one. To do this, we change the position of the saw to the opposite and start the baseboard on the other side.
How to make the skirting angle greater or less than 90 °
Not all angles have exactly 90 degrees. If the deviation is small, the gaps can be removed with sandpaper. In other cases, you have to mark and cut, taking into account the real degree. The main task in this case is to find a point on the floor where the two skirting boards will dock.
Let’s start by explaining how to cut the outer corner correctly if it is not 90 degrees. We take the bar, put it to the corner from one of the sides, firmly press it to the wall. as it should stand. Along the bottom edge of the baseboard, draw a line on the floor with a pencil. We put the bar on the other side of the corner, do the same. The intersection of the two lines will be the docking point of the two skirting boards.
How to dock a skirting board if the angle is less than or greater than 90 degrees
Now we again place the baseboard, set it in the way it will be attached. We make two marks: at the top at the turn, at the bottom at the place where the lines drawn by us intersect. Now an important task: it is necessary to make a cut on these marks. If there is a miter saw or miter box with an adjustable tilt of the saw. set it and cut it. If not, carefully cut with a hacksaw. In order not to get off, you can use a pencil to put a fishing line on which you need to saw. Similarly, mark and cut off the second part. We finalize the connection of the skirting boards with sandpaper.
Few professionals handle sandpaper joints. this is time and additional work. But if you join the baseboards in the corners in your own house, with your own hands, you definitely want everything to be beautiful. This requires this manual debugging.
If angles differ from 90 degrees
With an internal corner of a non-standard size, everything is exactly the same. We put the baseboard in the corner, draw a straight line on the floor. We do it on the other hand. Transfer the intersection point to the slats.
How and how to cut a plastic baseboard
All of the above applies to MDF skirting boards and wood. Cutting them with an ordinary hacksaw is not a problem. It is advisable to take a sheet of metal, as it has a finer tooth and saw cut is smoother, less work with sandpaper. With plastic, the situation is different. when you try to cut a piece, some thin-walled baseboards crumble and break.
Plastic cutting is not very convenient due to thin walls
To cut the normal quality of plastic skirting boards, you can use:
- Hacksaw for metal.
- angle grinder (angle grinder) with a diamond disk.
- Turning miter saw. Before cutting, accelerate the disk and only then start cutting.
- Jigsaw and file with a small tooth. Here you have to try. pick up speed and file.
- Sharp knife.
- Scissors for metal. In any case, direct cuts by them are easy to do.
To determine what is more convenient for you to cut a plastic floor skirting, only personal experience will help. If you have a miter saw, try using it. Not a problem a couple of times to try the angle grinder with a diamond disc. If all this does not give a normal result, try a hacksaw, a jigsaw or a knife. There are, of course, special scissors for plastic, but for a single use they are too expensive to buy.
Accessories for the design of corners and joints of PVC skirting boards
In plastic skirting boards, corners and joints can be formed using special fittings. There are external and internal corners, plugs and connectors. In principle, they allow you to assemble the desired configuration. Each manufacturer makes his own accessories. for his own profile, colors. But the principle of their use is the same.
How to make corners of a plastic baseboard
The first rule is that all cuts are made straight. Strictly perpendicular. Marks in the corners are set back 1-1.5 mm from the corner. The fact is that the accessories for rigidity have their own jumpers. Here for them it is also necessary to retreat a couple of millimeters, but no more. Otherwise, a gap will appear or the skirting boards will pop out of these corners.
Here is the result of the assembly
I must say that not everyone likes the look of plastic corners. You can make a corner on a PVC skirting board in the same way as described for wood or MDF. The only difficulty is that you have to be careful with plastic. it breaks down from excessive efforts. There is one trick. before cutting the plastic baseboard, add a little mounting foam on the back and wait for the polymerization to begin. It will be tougher, easier to cut, less deformation. If the foam subsequently interferes, it is not a problem to remove it, but cutting, and it is true, is easier.
How to connect with a door platband
You know how to make a corner on the baseboard neatly, but that’s not all. The room most often has doors. By the way, they must be installed before fixing the skirting boards. So, you still need to properly dock skirting boards with platbands on the door. If you just cut off exactly, it turns out roughly. There are stubs for plastic. not the most elegant way, but quite acceptable. Wooden can also be trimmed by cutting the “face” obliquely. Also “not ice”, but already something. And what to do with MDF skirting boards, because they drank unpresentable from them? There is a way to arrange a beautiful junction with the jambs. It will be necessary to make two cuts at an angle of 45 degrees (see photo below).
How to properly arrange the joint of the plinth and the door jamb
If the edge is not even, first we cut it off strictly perpendicularly. Relatively aligned edges make a cut at 45 degrees. A small cut off piece will be useful to us for making adjacencies. The second section is made at 90 degrees relative to the first, but if you lower the perpendicular from the corner, it also turns out 45 °.
How to make a neat fit to the door jamb
Now we take the first cut piece, apply it to the cut just made with the long side. It turns out a beautiful rounded slice. If there are chamfers, notches on the baseboard, they match perfectly. In the case of a wood pattern, one cannot be sure that the lines coincide. Anyway, such a junction of the plinth and door cashing is much more aesthetic.
