How to cut ceiling plinths correctly. How to cut corners of skirting boards: solutions for different materials

Ceiling plinth (fillet) is used for decorative finishing premises, giving the interior a complete look.

It is a linear profile with a porous structure and a shaped cross-section.

This material is very easy to use.

The only nuance when performing work may be the question: how to properly cut ceiling plinth?

Two adjacent moldings are connected at a certain angle.

Angles are external and internal.

How to cut the corners of the ceiling plinth so that their joining is of high quality?

There are several reliable and proven methods for cutting corners:

  • using a miter box;
  • using markings;
  • using a stencil.

Tools required for quality cutting:

  • miter box;
  • stationery knife or hacksaw;
  • pencil;
  • ruler.

About installation decorative beams read on the ceiling. What role do they play in the interior, what are they made from and how are they attached.

The same must be done with the second workpiece.

The intersection point of the two resulting lines on the ceiling is transferred with extreme precision to both planks.

From the marks obtained on the blanks, lines are drawn to the opposite corners of both baguettes.

This will be the cutting line.

The marking method must be carried out with maximum accuracy.

The quality of the resulting joint will depend on this.

How to properly cut the corners of a ceiling plinth using the two methods listed above more accurately?

The main rule when performing these works is the order: first, the joining line of two workpieces is adjusted, then the required length baseboards.

This sequence guarantees the possibility of several attempts to design a high-quality joining of two fillets.

Cutting outside corners

Using a miter box

Sawing blanks for the outer corner of the room is no more difficult than for the inner one.

Two baguettes are also taken and applied to the wall.

By crossing two moldings, the starting point of the cut is determined.

The baguette left from the corner is inserted inside up to the near wall of the miter box.

The hacksaw will fit into the far right and near left holes of the miter box.

The plinth to the right from the corner is arranged in the miter box so that the hacksaw fits into the near right and far left holes.

Another method

When designing an external corner using markings, the intersection of the two planks will be the upper point of abutment of the two blanks.

In the place where the baguette is adjacent to the wall, the lowest point of the cut is marked.

The connection of the upper and lower points becomes the cutting point for the planks.

When designing an external corner point, you can also use a homemade stencil.

The template can be made from thick cardboard using a protractor.

Then both opposite baguettes are alternately applied to the stencil and an even and neat cut is made with a metal hacksaw.

Design of non-standard corner points of the room

Non-standard corner points are unusual cases.

But there is a way out here too!

The molding must be cut into several small pieces.

The length of the cut pieces depends on the curvature of the angle.

The angle will be better and the fold line smoother if the baguette is cut into very small parts.

To avoid confusion, the order of each detail must be marked with a pencil.

By the time the small parts are glued, the straight plinth should already be glued to the base of the corner.

To non-standard corner point had a decent appearance, after gluing small parts they need to be cleaned and treated with sealant.

Gluing the ceiling plinth

The completeness of any interior is achieved after high-quality and accurate gluing of the ceiling molding.

It can be glued in two ways:

  • using putty ( this method applied before wallpapering);
  • on glue (the method is used after wallpapering).

Each method has its own advantages.

For example, with curved walls, gaps will certainly form between the baseboard and the wall.

IN in this case It is better to glue the molding onto putty so that you can immediately seal the cracks with the same putty.

Installation must begin from the corners.

The glue is applied in a thin strip to two opposite sides of the baguette.

One side will be adjacent to the ceiling, the other to the wall.

Galtel with applied glue it is necessary to stand for some time, and then press firmly to the place of gluing.

High-quality glue sets very quickly.

In this way you need to stick this decorative element along the perimeter of the entire room.

Ceiling plinth - how to properly cut the corners of the ceiling plinth

At first glance, installing a ceiling plinth may not seem like such a difficult task to us. But, alas, this is far from the case. In fact, during repairs, problems of various kinds may arise that can completely rid you of the desire to do the repairs yourself. Joining ceiling plinths in the corners can be one of these difficulties. Many apartment owners who decided to carry out renovations puzzled over how to install the ceiling plinth. However, it is completely unacceptable to simply cut it at an angle of 45°. And only masters of their craft can help out with practical recommendations in solving this problem.

How to properly cut skirting boards and make corners and joints in the corners?

An incredibly scrupulous and very significant feature in the specifics of installation lies in how to precisely trim and arrange it in all available corners. In fact, if you compare the baguette with an ordinary baseboard, it is equipped with respect to the base at an angle of 38-45 degrees. The generally accepted 45-degree angle cut at joint areas is sometimes very difficult to implement. When connecting ready-made edges with inside As a rule, gaps are likely.

Excellent results when cutting plinths are possible if the cut is made not only along the outer edge, but also from the outer side (optionally, if the work is carried out on the outer corner, an inner cut is added). Information on how to cut the corners of a ceiling plinth can be found in more detail using the video. The master carried out the cutting using a special miter saw. If you don't have it at your disposal, then home tool is also quite applicable for such a process. After the cut is organized, the texture of the cornice should be clearly visible on the back or front part.

How to properly cut a ceiling plinth with your own hands without the help of professionals?

Foam components would be more preferable for installation. They are a little easier to work with. First of all, you need to organize work on measuring inter-wall angles. If their value is close to 90°, then cutting the edges at an angle of 45° is required. This action must be done with the next trim. If the inter-wall joints are represented by any irregularities, then the radius of the corner is divided in half. Try not to confuse the parts: the baguette, the one that is fixed on the left side, should be equipped with a right cut, and the right fillet with a left one.

To make an internal corner, you must try to make sure that its lower section rises above the upper, and for an external corner - the opposite. The plastic and rather soft structure of polystyrene foam fillets eliminates the need to adjust them to each other, which can hardly be said about components made of wood or plastic. After working on the side sections, you need to estimate the plank to the ceiling for fitting. If necessary, cuts are made in the area where the base and accessory join. The work of rough joining the skirting boards is completed by fixing them with glue or screwing the fillets to the walls with further sealing of the seams.

How to properly cut corners of skirting boards, what tool to use for cutting and trimming corners?

To cut the corners of the ceiling plinth, it is recommended to work with a specialized tool. For installation of joints on professional level An electric miter saw or miter box can come to the rescue. With this toolkit high accuracy cutting will be ensured. You don't need any special effort for this. You just need to set the required parameters and start working with the saw blade. Among the least expensive methods, it is worth noting the choice of a hacksaw or a hand miter box. Simple has low price. But getting along with her is quite easy. The instrument is very crude. This is perhaps the only drawback. If used carelessly, the material can be damaged. Therefore, it is not worth saving on it. Having purchased material from low-grade wood or plastic, there is a risk of delamination into fibers. If you are using polystyrene foam, a saw is not required. A construction knife is quite suitable for this. Its blade must be impeccably sharpened. This will guarantee a high-precision cut and prevent delamination.

If you still haven’t managed to choose a cutting tool, then this is not a problem at all. You can safely go to the store and purchase fillets already prepared for joining. There is a different operating principle here. For frontal attachment of parts, it is recommended to make straight cuts rather than oblique ones. But their cost will be higher when compared with traditional accessories.

If you are going to cut the corners of the plinth in the room, then you need to start the work by purchasing a miter box. This makes it possible to select the required angle for working with a mounting knife or spatula, the dimensions of which will depend on the scope of the work being performed. To install a plastic structure, working with a miter box with low inclinations of up to 90° is quite suitable. Most likely, the most difficult stage is joining all the involved elements in such a way as to prevent the appearance of cracks. This time you will have to develop a sketch. The plinth is placed directly on the wall itself. If you don’t currently have a miter box in your tool kit, then using a stencil is quite possible.

How to make a corner on a ceiling plinth?

To make a ceiling angle on a ceiling plinth, you will need two important components: glue and a ruler for measuring angles. If the wall is level, measurements can be taken without any difficulty. But, if there are gaps, you will need additional measures. It is advisable to treat the corners with sealant in advance. In some cases, painting is desirable. Remember that the first thing you should do is decide what the corner of the product will be, and then do the rest of the manipulations, for example, cutting out the corner.

How to cut ceiling plinths in corners?

To cope with the task you need to know about certain nuances and prepare the appropriate tool. First of all, a mark is made on the length of the ceiling at which the baseboards are planned to be laid. The length at which the corner will be mounted and the cut will be made is measured using a miter box. Then sketches are prepared with length measurements. Cutting is done with a mounting knife. Miter boxes are now sold in almost all relevant stores.

How to cut ceiling plinth?

If you are planning repairs not at a professional level, then the most familiar tool will do. The radius of the corners should vary from 45 to 90 degrees. To eliminate common errors when cutting plinths, it will be important to develop a layout. This is quite acceptable when working with a plastic product. Its cutting is carried out using the edge of the miter box. If uneven edges are noticed, then cut with a mounting knife. In plastic skirting boards, it is better to be on the safe side by measuring several parts of the stucco molding, and only after that do their separation.

What are corners for ceiling plinths?

The corners of the ceiling plinth are also called baguettes. These products are pieces of plastic. They are characterized by a decorative component. Sometimes in everyday life it is possible to see such a name as ceiling cornices. Previously, their use was limited only to the decoration of public premises. Nowadays, cornices are used everywhere, including when decorating apartments. Also, measurements of the length of the ceiling are initially taken. Often, the production of ceilings comes down to the use of polystyrene, since its structure is quite compacted. Installing baguettes requires special concentration. Installation is probably no different from ceiling finishing. Now the market building materials rich in skirting boards of various styles and textures. The aesthetic component of the corner is decorative, and the practical component is the protection of the outer corner.

To hold wooden cornice The ceiling will require screws and nails. Installation will take some time, although the installation itself is not that difficult. Sawing corners and filing pieces requires great care. Areas of future joints should be treated. You will need cutting tools wooden products. The docking technology is almost no different from other types of such products. The main thing is not to forget to correctly prepare the calculations of the joints. Then the docking will go flawlessly.

How to join skirting boards?

For this process, you will definitely need a well-sharpened pencil and a stationery knife. First of all, measure the perimeter and length of the ceiling of the room, making appropriate notes in pencil. If the surface is smooth, a simple miter box will be quite suitable. It is suitable for installing skirting boards at small angles of 90-120 degrees. To create grooves for further arrangement, cuts are made. Then the bar is placed under the miter box. If the edges are uneven, it is advisable to use a utility knife.

What is a foam baseboard?

In the building materials market, polystyrene has long ago gained high purchasing power. Its installation is simple. It has become widely used for ceilings foam baseboard. All this has now become accessible and varied. You can find such a product in any store that sells repair supplies. These products have excellent decorative qualities. As a rule, plinths are sold in separate pieces. It is fastened using a stationery knife and a miter box. Having determined the length, it’s a good idea to make notes with a pencil.

How to cut a corner for a ceiling plinth?

How to cut a corner? During installation, first of all, knowledge of how to cut the corner of the plinth plays a vital role. To measure the angle, you need to take a protractor and a marking pencil. This will help to calculate which side of the corner the piece should be placed on. If there are any unevennesses, this is done with a miter box at a low angle. Next, cutting out the required corners is done using a stationery knife. If you are using a plastic plinth, then an approximate diagram will be useful to avoid mistakes when connecting existing elements.

How to cut the baseboard correctly?

To have an idea of ​​how to accurately cut a plinth during installation, you will need to use a stationery knife to uneven corners, as well as a miter box used for smooth surfaces. For plastic components, a hacksaw for metal will be most suitable. It will provide easy trimming, which must be carried out with extreme caution, pressing lightly on the saw or knife, so as not to accidentally injure your hand instead of cutting a corner. The miter box is only suitable for flat surfaces. Often the product is cut at a slight angle, presumably at an interval of up to 90 degrees. An ordinary stationery knife also copes with this mission perfectly. When making cuts, you should avoid areas with cracks.

What is a miter box for ceiling plinth?

This is perhaps an essential attribute for processing ceiling plinths. It is equipped with two sides of cutting ends. Cuts miter box at all possible angles from 45 to 90 degrees. The plinth ends up pinched on both sides. The cutting is carried out cutting tool. To correctly arrange the parts of the plinth you will need a pencil. They draw corners for joining. After everything is marked, the product is placed in a miter box so that it is on the surface. The plinth is held with one hand, and the material is cut with the other.

How to glue ceiling plinth?

In order to easily cope with this task, take into account the following basic rules:

  1. You need to start work from the corners of the room, since they are the simplest;
  2. Next, other parts of the room are involved in the preparation process;
  3. The corners are glued in such a way that there are no gaps;
  4. If the baseboard is made of plastic, then finishing putty is used for stucco moldings.

Apply primer generously to areas for fastening or plain water. After the putty mixture has dried, it is recommended to seal all existing cracks. Sealants of various compositions are usually used to seal them. Professionals advise using substances that contain acrylic. As a rule, no more than one package will be required for one ordinary room. In general, installation with sealant is similar to installation with putty.

Installing baguettes and skirting boards gives the renovation a finished and neat look, but only if the trimming is done correctly and all joints meet perfectly evenly. Used for pruning different instruments and methods that make work easier, but it is also important to take into account many nuances, which we will talk about today.

Types of ceiling and floor skirting boards, selection of tools

Installation of baguettes and skirting boards at least important stage repairs than any other. And cutting the corners is the most difficult part here. It is important to choose the right tool for the job and the most suitable cutting method.

Ceiling plinth

Ceiling molding, also known as molding, fillet, border or simply plinth, is most often used to finish the joint between a wall and a ceiling. Although sometimes it is used to cover internal corners, make decorative frames or panels, and decorate niches and architectural elements. There are several most popular materials for making ceiling moldings:

Plastic (polyvinyl chloride). It is more convenient to cut wide and rigid moldings with a hacksaw. If you need a more gentle tool, use a jigsaw.

Foam plastic (expanded polystyrene). A very light and porous material that is best cut with a sharp construction or stationery knife.

Wooden baguettes. Saws with helical sharpening, specially designed for baguettes, are suitable for cutting. You can also use hand or jigsaws.

Floor plinth

A modern floor plinth can hardly be called a plank that closes a gap. This is a structural component that complements the design and emphasizes general design. Skirting boards are made from several materials:

Wooden can be made of solid wood or veneer. For pruning use flat or circular saws, jigsaws.

Plastic skirting boards- “dangerous” competitors to traditional wood. Easy to install and cut with a regular hacksaw.

Aluminum skirting boardsthe last word in interior design. Usually cut with an electric saw or hand saw on metal.

Just on wooden skirting boards you will have to do a corner trim. The rest are cut straight and connected using special corners.

Types of angles

Corner joining and trimming of the plinth differs depending on the type of corner; they are distinguished: internal, external and non-standard.

An internal angle, in other words, an angle of a room less than 180°, is usually 90°. When trimming an internal corner, the lower part of the ceiling plinth always protrudes above the upper. The first step is to measure the angle between the walls; if it is standard and equal to 90°, then the planks are cut at an angle of 45°. The baguette that is glued on the right side should be cut on the left, and the left strip on the right.

The external or external angle is less common, it is more than 180°, usually around 270°. When working with such angles, everything is exactly the opposite. The edge of the plinth that will press against the ceiling should be larger than the bottom.

Non-standard angles. These most often mean angles with a degree greater or less than the standard of 90° and 270°, as well as various types of rounding. In this case, pruning is carried out “by eye” or with markings in place. Areas with curves are assembled from several small elements, each of which is adjusted in turn.

Methods for cutting skirting boards

If the corners are standard, it is most convenient to cut the baseboards using a miter box or stencil. In other cases, they resort to the method of marking in place.

Cutting a baguette using a miter box

A miter box is a carpentry tool that is designed specifically for cutting baguettes. It can be made of plastic, wood or metal. The shape resembles a tray with slits (grooves) on the walls. The miter box helps to correctly determine the angle of inclination and evenly cut the bar at 45, 60 or 90 degrees. Some models may have more graduation guides.

When working with a miter box, it is important to place the baguette correctly:

  1. The end cut of the baguette has the shape of an irregular triangle, so the side that will be glued to the ceiling is pressed against the bottom of the miter box, and the wall side against the wall of the instrument.
  2. The cut is made through opposite grooves. If you need to trim the baguette under internal corner, then he is stabbed to death under acute angle, and if external - under obtuse.
  3. Ceiling plinths are always laid against the nearest wall. The left part is placed on the left side, and the right part, respectively, on the right.
  4. Floor skirting boards apply to the far wall of the miter box, “away from you.” Corners are cut using the same principle.

A stencil is nothing more than a flat imitation of a miter box. It's not difficult to make. To begin with, you should arm yourself with a ruler, pencil and protractor.

On flat surface draw two parallel lines, the width between which should not be less than the width of the baguette. A perpendicular is drawn in the middle of the segments. All angles must be 90°. Next, this segment connecting the two parallels is divided in half and two more lines are drawn through the point at an angle of 45° from the perpendicular. Place a baguette on the stencil, just like in a miter box.

Cutting with pencil marks

This is another way to cut a baguette evenly without a miter box.

For the inside corner. The plinth is applied to the ceiling as it will stand, to the left of the corner, and a line is drawn on the ceiling. Then the segment is applied to the other side, to the right of the corner, and a line is also drawn on the ceiling. The two lines should form an intersection point. Again, apply the plinth pieces one by one and lower a straight line from the intersection point to the bottom edge of the plinth; it will be the cut line.

For outside corner. Place the plinth to the right of the corner and draw a line on the ceiling with a pencil beyond the corner of the wall connection. After this, apply the plinth on the left side of the corner and draw a second line to the intersection with the first. The intersection point is transferred to the upper edge of the baguette. The point where the corner of the walls and the inner bottom edge of the baguette meet will be the second mark. The two points are connected and the baguette is cut along the line.

Cutting wide molding with a pattern

If large drawing on the surface of the curb it falls exactly at the junction of the inner corner, it will have to be adjusted, otherwise general form will be spoiled.

A section with a pattern is cut out of the ceiling molding, leaving a 5 cm margin on the sides. The resulting area is divided in half, that is, an even cut is made in the middle of the pattern. After this, the baguette is cut alternately in a miter box or by eye.

Some useful tips that will help you in your work:

  1. Before you start making final cuts, it is worth practicing on a small section.
  2. The baguette should be cut from the front side, then the unevenness of the cut will remain on the back side.
  3. The cut can be carefully trimmed with a knife or sandpaper.
  4. The plinth should be cut on a hard, flat surface.
  5. If a miter box is used, for convenience it can be attached to work surface self-tapping screws.
  6. If the result is unsatisfactory and gaps at the joints are still visible, they can be carefully puttied.

If the corners in the room being renovated are even, you can buy ready-made corners for the chosen type of baguette and completely avoid the stage of cutting corners.

Skirting – finishing touch in the design of any bathroom. And this touch must be ideal or very close to it, otherwise the finish will have an unfinished appearance, which can lead to an unaesthetic interior as a whole. The ceiling plinth itself is quite easy to fix, but preparing it for work is not always easy. In particular, without knowledge of the matter it is difficult to make a neat corner - in attempts to get beautiful strips you can ruin a lot consumables. In order for you to avoid such an unpleasant situation during the process of renovating your bathroom, we will next tell you how to properly cut the baseboard in the corners: what tools to use and what methods you can resort to.

Trimming skirting board corners using a miter box

First, let's look at how to properly cut the corners of the plinth using a miter box - a carpentry tool that is a tray in the shape of an oblong inverted letter "P". This tool has special slots for cutting parts at angles of 45 and 90 degrees: a workpiece is placed inside the miter box, a hacksaw is inserted into the guides and the workpiece is cut at the required angle.

At first glance, everything is simple, but in the case of skirting boards there is a risk of getting tangled in the sides of the planks and causing a defect. To prevent this, we recommend working according to the following schemes.

Required Tools

For outside corner:

  • With the side that will be directly attached to the ceiling, place the plinth on the bottom of the miter box. With the other side, press the product against the wall of the tool, or rather, against its right slot.
  • Cut the required part of the plank using a hacksaw or utility knife.

Advice. Cut the plinth without excessive pressure, so as not to cause chipping or deform the workpiece.

For inside corner:

  • Press the plinth to the bottom of the miter box with the side with which it will be fixed to the ceiling. With the other side, press the bar against the left slot.
  • Cut off the corner. Attach the resulting strip to the first product and check how the sawn parts fit together. If gaps remain, carefully adjust the workpieces with a knife. At the same time, if the error is small and you are not sure that you can carefully work with a knife, choose a simpler way - after gluing the plinth to the ceiling, mask the gap with a putty of a suitable color.

Scheme for trimming parts

Trimming skirting boards without a miter box

Agree, not everyone has carpentry tools in their household, and buying them only for baseboards is not the most successful idea. But you still need to trim the corners, because the accuracy of the ceiling finish is at stake. How to be in this case? In fact, you can completely do without a miter box. There are even two ways to trim the corners of the baseboard without special tool: by resorting to markings on the wall and using a painted false miter box. Let's start with the first one.

You will need:

  • hard pencil;
  • ruler;
  • stationery knife or hacksaw.

The work is performed as follows. For inside corner:

  1. Attach a plank to the ceiling, which will be installed to the right of the corner. Draw a straight line along the ceiling along the outer edge of the baseboard.
  2. Place the strip on the opposite side of the corner and also draw a line on the ceiling.
  3. Mark the place where the two lines meet with a cross. Attach the strip to the corner and transfer the resulting mark to it, and then draw a neat line from it to the lower corner of the workpiece - along this line you will need to trim the plinth.
  4. Use a hacksaw or utility knife to cut the required angle.

Trimming skirting boards without a miter box

For outside corner:

  1. Place the strip to the right of the corner. Draw a line along the ceiling along the baseboard further from the corner.
  2. Place the baseboard to the left of the corner. Draw a line along the plank to the point where it intersects with the first line.
  3. Transfer two marks to the plank: the first is the place where the lines on the ceiling intersect, the second is the place where the corner of the room passes. Connect the two marks - you will get a trim line for the baseboard. Now all that remains is to cut off the corner and, if necessary, adjust the gaps.

Cutting a corner using a miter box

The third method of cutting the corner of a plinth is not quite usual - using a kind of false miter box. There are two ways to make such a “tool”.

The first is to draw a miter box. To do this, you can use ordinary thick paper or cardboard: draw two parallel lines on the sheet and, using a protractor or a simple square, mark the angles with the required degree. The corner is cut in almost the same way as in the case of using a carpenter's miter box: attach the plinth to the “tool”, make the necessary marks and make a cut along them.

The second way is to make a prototype miter box from three wooden planks: connect them in the form of an oblong letter “P” and make cuts at 45 and 90 degrees. You can use the same protractor to mark the corners.

Miter box made of wooden planks

When cutting the corners of the plinth without a miter box, it is very important not to miscalculate the length of the strip and the degree of cut itself. To avoid mistakes, at first it is better to cut the workpieces 10 cm longer, then try them dry on the ceiling and after that adjust them until you get the required result. In addition, let's not forget that not all bathrooms perfect angles at 90 degrees – you still can’t do without adjusting the products.

Advice. You need to fix the plinth strip to the ceiling only after you adjust the corner of the next plinth piece to it. It is best to try on the cuts not under the ceiling itself, but on the table - it will take more time, but the cut lines will be more accurate.

Thus, we have several ways to cut the ceiling plinth: using a miter box, without a miter box, using a kind of false miter box. Whatever option you choose to make the corners, it is important to do everything carefully and carefully - only in this case you will receive a truly effective tool for the final design of the ceiling, thereby making the interior of your bathroom aesthetically complete.

In order for the frieze to become a worthy decoration of your interior, you should take its selection and installation seriously. But if you don’t know how to cut the ceiling plinth correctly, everything can go wrong.

Trimming the frieze using a miter box

First, let's figure out how to cut the corner of a ceiling plinth. Most rooms are rectangular. Based on this, two adjacent fillets need to be cut at an angle of 45°. The accuracy of the cut will determine how neat the external and internal corners will be. It is not recommended to do such work by eye, since such liberties usually lead to damage to the fillets. It is best to use a high-quality factory-made miter box or build an analogue of such a device.

This is how you need to place the fillet in the miter box

Types of miter boxes

The simplest miter box models allow you to cut the baseboard at angles of 45º and 90º. More complex designs provide cutting at an angle of 60º. Most often they are made from plastic or wood, less often - from aluminum alloys. It is more pleasant to work with an electric miter box (miter saw), but purchasing one is expensive. True, if you have a large front repair work, then think about purchasing such a tool. After all, a miter saw allows you to cut any workpiece, including metal. In addition, trimming can be done either at a straight or at an arbitrary angle.

Of course, you don’t have to go to extremes and stop at purchasing a manual one, but professional tool. For example, a rotary miter box, which consists of a base with markings and a hacksaw, also allows you to cut at any angle. Of course, they are very convenient for cutting the corners of the ceiling plinth, but this tool is also quite expensive. Fortunately, there are more economical options.

The rotating miter box allows you to quickly cut the baseboard at any angle.

Trimming steps

Armed with an ordinary miter box, a knife or a hacksaw, we begin to fulfill our mission. So, how to cut a corner on a ceiling plinth using a miter box? Trimming steps:

  1. Place the baguette with the side that should be adjacent to the surface of the ceiling on the bottom of the miter box.
  2. Press the bottom of the frieze against the wall of the instrument.
  3. Saw off the fillet using a hacksaw along the miter box slot at an angle of 45º.
  4. Do the same with the adjacent baseboard, using another slot designed to form the same angle.
  5. Attach both friezes to the place of their further attachment. If there is a slight discrepancy due to surface unevenness, cut off the excess material with a sharp knife.

Please note: cutting skirting boards for internal and external corners is an identical process, the only difference is that different pairs of slots are used.

For trimming internal and external corners use different slots

Caution: when cutting the frieze, do not press too hard on it, otherwise the product may become chipped.

Making homemade instruments

Making a miter box with your own hands is not difficult; for this you will need three wooden planks. From them, a U-shaped structure should be knocked down, corners are marked on the walls, after which the box is cut. Now you have a wooden miter box with grooves cut out.

Alternative options for trimming fillets

Don't be upset if you don't have the necessary carpentry tools and materials to make it. The ceiling plinth can be cut without a miter box. You can:

  • draw markings on the wall;
  • draw a miter box template on paper, cardboard, plywood;
  • use a miter saw;
  • trust the eye.

Attention: to avoid having to cut the baguette at all, use the special internal and external corners for fillets. The fittings are glued to the corners of the room, after which friezes are inserted into it on both sides.

Marking

You can cut the ceiling plinth using markings. Let's start with the inner corners.

You will need a plinth and a pencil. Lean the frieze against the corner of the wall. After this, you need to draw a straight line on the ceiling along the baguette. The first stage is completed.

We draw a line over the adjacent baseboard adjacent to the first. It should also be cut at a 90º angle. However, you can take the same fillet that you used when drawing the first line.

The boundary of the upper part of an adjacent baguette

Place a dot at the intersection of the lines. It should be alternately transferred to two friezes, from which the internal corner will be formed. Draw a straight line with a pencil from a point to the nearest corner of the opposite side of the fillet.

Using a utility knife, cut off the excess frieze along the marked line. Do the same with the second baguette. We connect the cut fillets and make adjustments if necessary. The final stage is installation of the plinth.

To make an inside corner, place the fillets on the desired sides one at a time, drawing lines both above and below the curbs. We transfer both intersection points of adjacent friezes to the plinth and connect them. Thanks to them, you will learn how to cut the ceiling plinth in the corner, because the resulting line will be the cut line. Carefully remove excess and connect the friezes. If the angle is adjusted successfully, you can begin installing the baguettes.

You will get two points where the friezes lines intersect

Trimming with a template

You can draw something like a miter box on a piece of paper, cardboard, etc. Draw two parallel lines horizontally on the selected material. Use a protractor to mark out the corners. Use the template as you would a miter box. Differences: there is nothing to press the bottom edge of the baguette against; there is no need to get into the grooves due to their absence. This miter box is recommended to be used when the corner of the room is not straight.

Drawn template for replacing factory tools

When can you use an eye meter?

Due to the non-standard nature of some corners, for example excessive roundness, they can be formed from four or more parts of a baguette. Then the fitting will most likely have to be done by eye, constantly checking how well the cut out elements fit together. It is necessary to carefully align each subsequent part with the cut of the previous one.

You have the right to choose any tool for cutting baguettes that you want. But experts still recommend using a miter box, especially if all the corners in the room are right. Even the most simple model this carpentry jig much more convenient than a drawn template. To finish non-standard corners, you should consider other cutting options or purchase a rotary miter box.
