How to cut a corner 45 on a plinth

Inner corner

First of all, it is necessary to consider the technique of how to cut the inner corner of the ceiling plinth. After all, in any room they are. If there are no external corners in ordinary rectangular rooms, then these varieties will have to be cut in any case.

corner, plinth

A plinth is placed on the bottom of the miter box with the side that will adjoin the ceiling. The bottom of the fillet will be pressed against the wall of the tray.

If the material is hard, it is cut with a metal saw. Soft items can be easily handled with a sharp knife. In this case, the angle should be equal to 45 degrees. If the pressure during cutting is too strong, hooks and chips will form on the plinth. An adjacent corner is cut in the same way.

Before gluing, they are applied to the wall and, if necessary, small irregularities are corrected. There should be no gaps between the skirting boards. If this is the first time this work is done, you can practice on small pieces.

How to cut corners on skirting boards? Step-by-step instructions, practical tips and advice

Repair is a responsible and costly undertaking. Although you can save a lot if you carry out the work yourself. Cosmetic finishing of the premises is carried out according to certain technologies. You can decorate the interior using a variety of materials.

Today, a very popular technique is the use of skirting boards to hide irregularities between the walls and the ceiling. In order for the contour to be aesthetic, it is necessary to do the work carefully. How to cut corners on skirting boards will help you understand the advice of experienced construction and repair masters. They will tell you how, using various tools, to perform the necessary manipulations with decorative finishes of various types.

Homemade tool

Don’t you have a miter box? No problem! You can do it yourself. When pruning for the first time, it is best to apply it in your work. This will require a plywood board, paper or cardboard.

Interested in how to cut the outer corner of the ceiling plinth, as well as its internal varieties, you need to take this approach into service. Draw two parallel mowing lines on the selected material. Next, using a protractor, angles of 45 degrees are made around the edges.

A homemade tool is applied to the plinth, making the appropriate notes. The pruning technique is the same. The miter box is not used if the walls in the room are very uneven. When creating an angle of 45 degrees, gaps between the joints are obtained due to such inconsistencies. Therefore, pruning is done in the previous way. Before editing, the edges must be corrected.

Skirting board material

Experts agree that polyurethane is the best material for the presented finishing products. But even he has a number of disadvantages. These should be taken into account before cutting corners on the skirting boards. Polyurethane is susceptible to temperature changes. Therefore, it is not used for decoration in the kitchen or bath. Otherwise, the skirting boards will quickly crack and lose their aesthetics.

Expanded polystyrene has almost all the positive characteristics inherent in polyurethane. But it is still more fragile material. It’s easy to break.

PVC skirting boards are relatively cheap. But it is very easy to leave dents or gouges on them. Therefore, work with such products should be very careful.

Wood looks very nice, but not in all interiors. In addition, it is rather difficult for a non-professional craftsman to work with such material. Do you want to make repairs with your own hands? Then you’d better still choose polyurethane or expanded polystyrene.

Work without a miter box

The polyurethane skirting board looks very nice in the interior. How to cut corners on such a product so as not to spoil its appearance? And here an inexperienced master will be helped by expert advice. Not always a home craftsman has at hand such a tool as a miter box. You can do without it.

For this, the markings are performed directly on the wall. First, the required length of the decorative item is measured. It is cut at right angles. Next, each detail is applied to the ceiling. Their contour is outlined with a pencil. This produces an intersection. It is applied to both skirting boards.

An inclined line is drawn from the point of intersection to the edge. This is the clipping boundary. Correct it before gluing by attaching both skirting boards to the corner. This is a fairly simple method, but even it requires a good eye and accuracy in work.

Outside corner

Quite often, the contour of the walls in a room has a complex shape. In this case, you will need to figure out how to cut the outer corner of the ceiling plinth. To do this, it is laid on the bottom of the miter box in the same way as in the previous version, with the side that adjoins the ceiling.

Other slots are used for these corners. They also have a slope of 45 degrees, but are on the other side. Further, after marking and trimming, 2 plinths are applied to the corresponding place on the ceiling. Adjustment in progress.

Difficulties can arise when it is necessary to cut the same skirting board on one side for the outer corner, and on the other for the inner one. Many people make a mistake here. First you need to cut the inner corner. Otherwise, a skirting board that is too shortened will not dock in any place.

General characteristics of finishing

Studying the question of how to properly cut a corner on the ceiling plinth, you should familiarize yourself with the features of such a finish. The stucco molding between the ceiling and walls is now made of artificial materials. It can be polyvinyl chloride, expanded polystyrene or polyurethane. Wood can be used from natural materials.

In the construction business, the ceiling plinth is called (scientifically) a fillet. Of all the materials from which such finishing elements are made, polyurethane is considered the highest quality. Therefore, it is better to choose it. Next, let’s try to figure out how to cut the corner of the ceiling plinth. Expert advice will help you do this job well.

Form, fittings

When studying the question of how to properly cut a corner on a ceiling plinth, you should pay attention to its shape and related products. There are embossed and smooth fillets. Their width and length can vary significantly.

When choosing the size of the skirting boards, take into account the type of interior, as well as the height of the ceilings. For a small room, where the distance from floor to ceiling is no more than 2.75 m, wide skirting boards will not work. They will look out of place. For the same reason, a narrow fillet should not be used for high ceilings. In such rooms, a 45 mm plinth looks good.

For installation, you can purchase curly corners from the same material as the fillet. They are external and internal. But quite often the skirting boards are joined without them, directly. In this case, you need to perform an even, beautiful trimming of the corners.

Docking the skirting board

Having studied the information provided in detail, you can answer the question of how to cut a ceiling plinth using different methods for solving this problem. But besides this, you need to know effective ways to connect the planks.

One of the ways (which has already been mentioned) is based on the use of connecting elements.

They are available for external corners, for internal corners, as well as for connecting skirting boards in straight sections. A very convenient way to save time and, in some cases, financial resources.

Even experienced specialists will not be able to mount skirting boards for ceilings so that everything is perfectly smooth and beautiful.

In order for the quality of the work performed to be at the highest level, you must use the following recommendations:

  • on straight sections of the plinth, you need to connect so that one part slightly covers the other;
  • after applying glue at the junction, the residues must be wiped off;
  • all gaps between different parts or between skirting boards and ceiling / walls must be sealed with a sealant (alternatively, putty with water-based paint).

Material for the production of ceiling slats

The first skirting boards were made of plaster. But they did not last long in the building materials market (the main reason is the high cost of gypsum plinths), giving way to products made of foam, wood and expanded polystyrene.

Before proceeding with a detailed analysis of the question of how to correctly cut a corner on the ceiling plinth, it is necessary to find out what are the features of each category of the presented products.

Polyfoam is the most economically profitable material for the manufacture of ceiling plinths. The main advantages of this category of products are:

  • low cost;
  • looks great on the ceiling;
  • it is not difficult to choose skirting boards that harmoniously fit into the interior of almost any room;
  • well cut;
  • these skirting boards are easy to work with.

There is also a “reverse side of the coin”. foam products break easily, but many experienced experts argue that this fact is not a serious problem (the skirting board is not physically affected on the ceiling).

Even if you do not know how to properly cut the corners of the ceiling plinth, you can practice on products from the category presented (cut pieces, etc.).

Expanded polystyrene, which is used as a material for the production of ceiling skirting boards, is stronger than polystyrene, but this criterion negatively affects the cost of products.

The main advantages of the presented category of skirting boards are their high strength, long service life and the ability, without strong physical efforts, to cut off the corners you need.

Wood products are more expensive and look more solid than the above products. But the presented category of ceiling plinths is difficult to machine.

In order to cut off a corner, you will not only have to work with a hacksaw (experienced experts recommend using a blade for metal), but also eliminate irregularities using a sandpaper.

The question of cutting the corners of the ceiling plinth must be resolved taking into account the materials used for their production. For example, to prepare foam products, you can use an ordinary clerical knife, which will be a poor helper if you are installing wooden skirting boards.

How to make a miter box without the help of specialists

If you do not have a miter box, but you know that you can use it to prepare ideal angles, then make this device yourself.

To do this, you will need:

  • three small boards;
  • nails;
  • hammer;
  • hacksaw for metal.

Make a small U-shaped tray with cuts that form the corners necessary for your task. The main thing is not to rush, carefully check your incisions (preferably with a protractor) and make sure that your structure is stable.

If you know how to cut a corner of a ceiling plinth, but for this you need a device that allows you to cut off non-standard corners on fillets (another name for plinths), make the necessary tool with your own hands.

To do this, you need to connect two rectangular boards with the letter “G”, and make cuts on one of them. On paper, using a protractor, you need to draw a mowing line so that they form the necessary angles with one of the boards. The device is ready, it remains only to test its functionality in practice.

As a last resort, you can always find some kind of thing that will help you cut off part of the baseboard at the right angle (book, table pushed against the wall, etc.).

An important point! When making measurements, keep in mind that for the outer corner of the ceiling plinth you need to take a margin equal to its width (fillets, in this case, protrude outward).

How to cut a ceiling plinth without special tools

If you do not have a miter box and the desire to make it using the above recommendations, try to cut the plinth without using a special tool.

To do this, you need to attach the fillet to the ceiling (only the way it will be fixed) and draw the line.

A similar operation is carried out with another wall forming an angle. The intersection of the two lines will show you where to cut off a piece of the ceiling plinth. To do this, you must once again attach the plank to the ceiling and draw the line from the specified point to the end of the plinth, to the bottom corner.

If you need to prepare the material for the outer corner, use the following algorithm:

  • On the right side, a plinth is applied to the ceiling and a fishing line is drawn along it.
  • A similar operation is carried out on the left side of the corner.
  • On the plinth, you need to make two marks: the place where the corner of the room passes and the point of intersection of your lines.
  • After connecting these points, you will receive the necessary cutting line.

Among the main disadvantages of the presented method, it is necessary to highlight the fact that sometimes there are significant errors, the cause of which may be: a human factor, a bad pencil or an uneven ceiling / walls.

Preparing corners with a miter box

Builders, carpenters and renovators are familiar with this device.

Miter box. a special wooden tool with slots, in the form of an inverted “P”, which allows you to cut a board or plinth so that an angle of 45 or 90 degrees is obtained.

In addition to this device, you will need a clerical knife, a hacksaw for metal and a sandpaper if you are working with wooden skirting boards.

The preparation of the corners should be carried out without undue physical effort so as not to damage the skirting.

Experienced experts recommend adhering to the following procedure:

  • At the bottom of the miter box, you need to lay the side that will contact the ceiling, and the lower part is pressed against the right wall.
  • The adjacent corner is prepared in the same way, but the plinth is applied to the left wall / slot.
  • The resulting cuts are applied to the corner, if you have a large gap, trim the irregularities with a clerical knife.
  • In the case when a small gap is observed between the prepared skirting boards, remove it after fixing all the elements using a putty.

To do this, it is enough to cut the strips at right angles and then insert them into the connecting element. But this solution to the issue cannot always be applied in practice.

Very often the connecting part looks ridiculous, stands out strongly against the general background and spoils the appearance of the room.

The main disadvantage of preparing skirting boards using a miter box is the fact that this method is only suitable for rooms where the angle between the walls is 90 degrees.

Any deviations or irregularities can prevent you from performing this work efficiently. And one more advice from experts.

If you are inexperienced in preparing skirting corners, practice on scrap or unusable material before proceeding with this task.

How to cut a corner on a skirting board: professional advice

The appearance of the ceiling in your home, apartment or office largely depends on the choice and installation of ceiling plinths. It is not only the color, material, width and other parameters of the presented elements of the decoration of the premises that play a role, but also how they are prepared and mounted.

In order to prevent irreparable mistakes in the process of fastening the planks, you need to know the answer to the question: how to cut a corner on a ceiling plinth without asking for professional help.

A few tips from experts

If you are interested in the question of how to cut corners on a ceiling plinth, from a theoretical point of view, or you plan to make repairs in the indefinite future, then you should remember some tips:

  • when making repairs indoors, make sure that all the elements not only create an overall beautiful picture, but also “dock” with each other;
  • you should not buy wooden skirting boards if you do not know how to work with it;
  • fix the planks only after they are fully prepared (you are unlikely to be able to clean up irregularities on the glued ceiling plinth);
  • installation of ceiling strips should be carried out, starting from the corners, according to the principle: “from complex to simple”;
  • when buying ceiling plinths, take the material with a margin (not only taking into account possible errors, but also to compensate for losses on uneven walls).

Practice shows that trimming the ceiling plinth, despite the complexity of this process from the position of beginners, after “passing” several corners, is perceived much easier. But doing similar work in a room with rounded corners can be a major challenge, even for professionals.

Typically, these problems are solved using a method that is based on creating “patches” where the bottom is wider than the top. This work requires perseverance, a good eye and accuracy.

After a detailed study of the question of how to cut the ceiling plinth in the corners, even a person without experience in this field of activity will be able to independently perform this task at home.

As a result, you will not only save money, but also get moral satisfaction after the repair work.

How to properly cut a corner on a ceiling plinth

Ceiling plinth, also known as fillet, frieze or baguette, is a finishing material that is used at the final stage of renovating a room. At the same time, it not only masks possible irregularities of the upper edge of the wallpaper or peeling of plaster near the ceiling, but also acts as a decorative element, giving completeness and uniqueness to the space.

Ceiling plinth with internal and external corners

Many people install the ceiling frieze in their apartment on their own, without involving masters. This job is not that difficult if you know how to choose the tools and cut the corner correctly on the skirting board. The main thing when working with a ceiling molding:

  • take into account the peculiarity of the material from which the fillet is made;
  • have the right tools and use them correctly;
  • know the intricacies of step-by-step work.

Skirting tools

When installing friezes, you need to prepare the necessary tools to perfectly cut the skirting board and fit the ceiling frieze to the corners of the room. To trim the baguette, a miter box and cutting tools are used: knives (carpentry and ordinary), hacksaws, saws. When handling each of them, it is necessary to take into account the features of the device and the subtleties of application.

The miter box is a device that guides the cutting tool blade with the required inclination. It is specially designed for cutting materials that are then mounted at a specific angle. Structurally, it can be conventional and tilt-rotary, or precision. They are visually different, but the principle of operation is the same.

Different types of miter boxes Plastic miter boxes with clamps

An ordinary miter box is a U-shaped tray made most often of plastic. It also comes in metal or wood. There are slots in its walls for guiding the cutting tool at a given angle to the base. This variety has a template type and cannot be adjusted: the material is cut at standard angles (normal or negative), which are structurally embedded in the grooves. When choosing a miter box, you need to look so that it should be wider than the workpiece for cutting. To fix the material in the device, a clamp or special pins can be used. if the structure has perforations for their installation. Usually, the workpieces in it are simply adhered to with the free hand.

A hacksaw is a widely used cutting tool for cutting a baguette. It is necessary to carefully approach its choice: the canvas must correspond to the size of the slots of the miter box. be of sufficient thickness and width. When working with a hacksaw, it is necessary to observe the inclination of the tool so as not to damage the miter box and observe the correct direction. At the same time, the cut of the part often turns out to be not very smooth and sometimes requires alignment and grinding.

Materials for ceiling plinths

Ceiling moldings can be of different widths, have a convex pattern on the front side and special recesses for engineering systems on the back side. Fillets are made in specialized production from polystyrene, its varieties. expanded polystyrene, polyurethane and wood.

Polyfoam is the most affordable finishing material. Its positive qualities: light weight, ease of cutting and processing, the possibility of finishing by painting in any color. Negative point. granularity and low strength. even a slight mechanical damage can violate the integrity of the foam surface.

Varieties of foam plinth Foam plinth on the ceiling

Expanded polystyrene is a more durable type of foam. It is also light in weight and in processing, but it has a higher density and a smooth surface, is more resistant to mechanical damage, and lends itself well to staining. These two materials, due to their low weight, have little stress on the load-bearing walls.

Wood is the hardest and most impact-resistant of all fillet materials. Products made from it retain their appearance longer and are able to withstand significant mechanical stress. In the style of some interiors, it is wooden friezes that are most applicable. Wood ennobles the room and fills it with warmth. However, it has a higher price than previous materials.

Different types of baguettes made of wood Wooden fillet in the interior

Products made of polystyrene, as well as expanded polystyrene, have an advantage over wood. The softness of the material makes it possible to press the baguette as tightly as possible against the wall, ceiling and each other. therefore, there are no gaps. It is possible to achieve excellent joining of the plinth on not perfectly flat walls if you use a not wide foam or expanded polystyrene fillet.

Trim skirting in miter box

The miter box is one of the most important tools when processing a baguette, allowing you to make cuts on the skirting board with the desired slope for an even joint. Consider the features of working with fillets using this device.

To correctly and evenly cut the ceiling plinth using a miter box in the corners, you must follow certain rules.

  • Cutting workpieces with a miter box is only suitable for right angles equal to 90 °.
  • When cutting a baguette intended for the ceiling, it is applied and sawn on the inner side of the miter box closest to you.
  • The workpiece is installed in such a position as it will be mounted later on the ceiling.
  • Cutting is carried out on the front side of the baguette.
  • The side that is subsequently glued to the ceiling must press firmly against the bottom of the tray when cutting.
  • It is recommended to use a specific cutting tool for each type of material: a hacksaw or knives are good for cutting soft materials such as foam, a saw is preferable for wood.

Ceiling corners can be internal and external, or external, therefore there are differences in the preparation of the baguette, which consist in the methods of joining the planks and different inclination of the cuts. To make it easier to work with the miter box, it is useful to make visual prompts on it in the form of small stickers with inscriptions, as shown below.

Miter box with tips for easier work Angle types

The main attention should be paid to the accuracy of cutting workpieces at the desired angle. It is recommended to start working from the inner corner and then work to the outer corner. Otherwise, it is possible that the length of the baguette will not be enough. Schematically, the cutting steps look like the figures below.

Fillet cutting for inner corner

Internal corners are always present in rooms. so you will definitely have to face them when installing skirting boards on the ceiling. In this case, when cutting a baguette, we follow the algorithm:

  • we measure the required length of the workpiece by attaching it to the ceiling at the place of future installation;
  • we place the bar in the miter box along the near wall so that its location coincides with how it will be mounted on the ceiling;
  • holding the plinth, we put the cutting tool in the groove with an inclination of 45 ° and cut the workpiece without unnecessary pressure;
  • we do the same actions in a mirror image for the second, adjacent bar. For the convenience of cutting, you can turn the miter box with the bar installed in it to the desired hand.

Knowing how to correctly cut out the inner corner on the ceiling plinth with a miter box, you can easily arrange more complex ones. outer corners.

Fillet cutting for outer corner

Outside corners in a room are not so common, but they require particularly careful cutting of fillets and precise joining of their sides. Unlike the internal ones, small gaps in the external ones are more noticeable and difficult to hide. You also need to take into account some peculiarities when working with external corners. It’s easy to do, following certain rules:

  • parts of the frieze should protrude slightly from the edge of the wall, forming a small margin;
  • we measure the bar by attaching it to the ceiling as it will be glued in the future;
  • we place the frieze in the miter box, pressing it against the wall closest to you;
  • we insert a hacksaw or other suitable cutting tool into a groove with an angle of 45 °, and cut off the workpiece without unnecessary pressure;

The location of the left outer strap in the miter box

  • we put the adjacent bar to the nearest wall of the miter box and, holding it, insert a hacksaw or other tool into the groove at an angle of 45 °. For the convenience of work, we unfold the miter box with the blank “under the arm”;
  • we do the same as in the previous case. carefully and evenly cut the fillet.

It remains to join the cut baguette strips and check the cutting accuracy. Taking the cut pieces of the baguette in pairs, we join them, forming an inner or outer corner. If the cutting of the planks was carried out accurately and accurately, then the edges of the adjacent planks will ideally coincide with each other.

In the presence of small irregularities and roughness, it is allowed to work on them with a sharp knife, clean them with a file or emery paper fixed on a bar.

How To Cut a 45° Angle (With a Hand Saw)

Making an external joint

In apartments or houses, there are not only internal corners, but also external ones. In this case, the nearest inner corner is first trimmed and modified. When it’s ready, you can make an outside 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, we 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, choose the appropriate position. In order not to be mistaken, all the time imagine how the plinth is against the wall and what you should get.

We cut the second segment at 45 degrees so that it joins the finished one. To do this, we change the position of the saw to the opposite and start the plinth on the other side.

How to saw down the corner of the plinth at the right distance

The second and all other corners of the skirting boards must be made at a certain distance. If the next corner is again internal and the distance to it is less than the length of the plank, use the same fragment on which there is already a cut. 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. We combine the beginning of the measuring tape with the ledge, measure the required distance, make a mark with a pencil. She will be the starting point for the cut.

You need to know at what distance to cut

Plinth with a mark is placed in the miter box, the desired direction of the cut is chosen. The dash can be combined with a hacksaw blade or with a slot in the miter box. As it is convenient for anyone. Cut off. This segment must be “tried on” in place. If both corners rest against opposite walls or the gap is only 1 mm, everything is fine. You can cut a second strip from a new piece to design a joint. And again we remove the flaws with sandpaper.

If the length of the wall is longer than the length of the plinth plinth, take a new plank. We will cut the second corner on it. It is important not to be mistaken in which direction to cut. Having installed both planks along the wall, mark the joint on one of them, make a straight cut. For a straight cut, there are also slots in the miter box. So there won’t be any problems.

But the joint in a straight line does not always look perfect, and during operation it often diverges, forming a visible gap. If you wish, you can cut off at an angle (any) two planks.

To do this, first cut off the edge of one plank at an angle, mark the second joint. The mark is placed on the side of the plinth that is pressed against the wall. At this mark, 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 oblique. It is more accurate. The difference is especially visible on wooden skirting boards and MDF. Cut, again, bring “to mind” with sandpaper.

The first joint in the room

The first plinth should be cut as close to the edge as possible. Carpenters have their own jargon and they say “cut” the corner. It does not matter what you call it, it is important that in the miter box we set the bar so as to make a cut at the very beginning. For the cutting line, we push the bar a short distance, for a start, you can 1-2 cm. Cutting a smaller piece is more difficult, so save the savings “for later” when at least some skill appears.

In the miter box, place the plinth at the far wall “facing” you. This makes it easier to check if you are cutting / sawing correctly.

Then you need to make a corner on the plinth like this:

  • We put the plinth 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 picture below).
  • Move the bar so that it goes slightly beyond the cut line.
  • Cut off.
  • We take the second piece of plinth, repeat the same operations, but change the position of the saw on the miter box 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 properly cut a floor plinth in a miter box: for external and internal joint

We got two pieces cut for joining in the inner corner. To make the joint perfect, we 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 small grain, we achieve a tight joint without cracks and gaps.

When joining the skirting boards in the corner, use a transparent silicone sealant. Before installing the fasteners, a layer of silicone is applied to the cut. Immediately after the plinth is fixed, we remove the excess that appeared on the outside. We clean up to an absolutely clean surface. This way of connecting the skirting boards in the corners looks more neat, dirt and dust does not clog into it.

Types of corners in rooms

When installing skirting boards, you need to arrange the corners in some way. By their appearance, the corners are external (which protrude forward) and internal (for example, corners in a room). In rooms with normal geometry, the corners are straight, i.e. 90 °. When joining two pieces of the plinth strip in the corner, they are cut so that each has an angle of 45 °.

To arrange the outer and inner corner, the skirting board must be cut

But how to make an angle on the plinth so that it is exactly forty-five degrees? To do this, use a special carpentry tool. miter box.

Miter box for skirting boards

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 a miter box yourself by assembling a guide from the boards and making cuts in the walls. There are various models on sale ranging 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 correctly cut the skirting board for a perfect fit.

Professional carpentry miter box. a tool with a wide range

The simplest miter box is a plastic U-shaped profile, in the walls of which slots are formed. These slots are used as a hacksaw guide. 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.

How to cut a plinth at 45 degrees? One way is to use a miter box

Sometimes a hacksaw is included, sometimes not. Usually the ones included are not very good. Any hacksaw can be used, picking up the blade for the material that is planned to be cut. It is important that the blade moves freely in the slots.

How to cut the skirting board correctly. Miter box for cutting corners

When installing skirting boards, it is important to arrange the corners correctly. It is they who often spoil the overall picture. How to make a corner on the plinth. external and internal, how and with what to cut. We will discuss all this further.

How to make a skirting angle more or less than 90 °

Not all angles are exactly 90 degrees. If the deviation is small, the cracks can be removed with sandpaper. In other cases, you will 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 two plinths will join.

Let’s start by explaining how to properly slice the outside corner if it’s not 90 degrees. We take the bar, put it to the corner on one side, press it tightly against the wall. as it should stand. Draw a line on the floor with a pencil along the bottom edge of the plinth. We apply the bar to the other side of the corner, do the same. The intersection of the two lines will be the joining point of the two skirting boards.

How to join a skirting board if the angle is less than or more than 90 degrees

Now we attach the plinth strip again, set it in the way it will be attached. We make two marks: at the top at the turn itself, at the bottom in the place where the lines we draw intersect. Now an important task: it is necessary to make a cut according to these marks. If you have a miter saw or a miter box with an adjustable saw tilt, set it up and cut it. If not, carefully cut it with a hacksaw. In order not to get lost, you can use a pencil to apply the fishing line along which you need to cut. Similarly, mark and cut off the second part. Modifying the connection of the skirting boards with sandpaper.

Few of the professionals process the joints with sandpaper. this is time and additional work. But if you join skirting boards in the corners in your own house, with your own hands, you definitely want everything to be beautiful. This is what this manual tweak is for.

Begin installing the skirting boards in one of the corners. If this is your first experience, choose the part of the room where something will stand. Not always, it’s over, the first pancake is lumpy, but it’s still better to insure yourself. To make the corner on the baseboard neatly, work slowly. One was sawed off, checked, adjusted. Let’s move on to the next one. It is better to fix it after the two adjacent corners are assembled. But you should not postpone the assembly too much.

Trimming skirting boards in corners requires some skill. But by making 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 also on the floor. It doesn’t matter which side to turn it, it is symmetrical. Insert the bar into the profile, turn it so that it will stand against the wall. When washing down a floor plinth in a miter box, the “wall” is the wall that is farther from you. Once again: press the plinth strip firmly against the back wall in the position in which it will be installed. Insert a hacksaw into the desired slots. You can start sawing.
