How To Cut A Ceiling Plinth Without A Miter Box


Ceiling plinth performs not only a decorative function, we visually separate the walls from the ceiling, but can also hide the joints of various finishing materials of the ceiling and walls. Not every interior design involves the use of a skirting board, but more often than not, the overall appearance of the room seems incomplete without it. There is nothing complicated in fixing this element. fillets. almost all types of skirting boards are attached with glue. But the question of how to properly cut the ceiling plinth in the corners of the premises can confuse many. Indeed, even in the simplest room there are internal corners, where the plinths of the ceiling plinth must be precisely and beautifully docked. And in a more complex configuration of the room, you will also have to dock the skirting boards, performing the outer corner. In this article we will look at various options for how to cut a ceiling plinth with and without tools at hand.

First you need to figure out how to cut the ceiling plinth, the answer to it depends on the material from which the fillet is made. At the moment, we sell ceiling skirting boards made of polyvinyl chloride (PVC), expanded polystyrene (foam), hydro and wood.

PVC ceiling skirting boards are the cheapest. Dents and creases are easily formed on them, which cannot be removed, so the product has to be thrown away. Also their disadvantage is electrostaticity. the ability to attract dust. You can cut them with a sharp construction knife or hacksaw.

Styrofoam ceiling skirting boards are also cheap. This material is very fragile, it crumbles easily during processing, therefore, it is necessary to cut the expanded polystyrene with a sharp knife or a hacksaw on metal, and not making too strong pressing forces.

Ceiling skirting boards made of extruded polystyrene foam are slightly more expensive than polystyrene foam, they are denser and more difficult to cut. However, they crumble less, making them easier and more comfortable to work with. Cut with a construction knife and a hacksaw for metal.

Polyurethane ceiling skirting boards are the most expensive at the moment. They are durable, elastic and moisture resistant, can be easily cut with a construction knife and DO NOT crumble. The disadvantage of polyurethane skirting boards is their dependence on temperature changes. For example, over a gas stove, a polyurethane skirting board will permanently deform and crackle slightly. If you try to process or cut such a plinth, it may bend or deform in a second way.

Wooden ceiling skirting boards are dense, heavy products that can only be cut with a hacksaw, preferably with fine, dense teeth. You can also use a cloth for metal.

Before proceeding to the enumeration of the ways how to properly cut the ceiling plinth, I would like to note that there is a possibility NOT to cut the plinth with particular precision. On sale there are special corner elements, into which the edges of the skirting board are inserted. In this case, it is enough to cut the plinth strip at an angle of 90 °, and the corner element will hide all the flaws. But this method is not always used, since the dimensions of the corner elements are slightly larger than the baseboards themselves, so the corners in the room will stand out against the general background. Sometimes it can look bulky. However, if the design of the room allows the use of corner pieces for ceiling skirting boards, it makes sense to use them. Further instructions will be useful for those who nevertheless decided to accurately cut the skirting boards at a given angle.

How to trim the corner of a ceiling plinth using ceiling markings

Marking the skirting board on the ceiling also allows you to cut the corner straight and precisely. The only drawback of this method is that it is difficult and inconvenient to keep the plinth plinth suspended during the cutting process. For the rest of the tent, the angle for cutting in this way can be even more accurate than in other ways. Applying the plinth to the installation site, all wall flaws and deviations in the angle size are immediately taken into account.

Cutting the corner of the ceiling plinth:

  • First of all, two workpieces must be cut at an angle of 90 degrees.
  • Then we first apply one plank, rests its end against the perpendicular wall. We draw a line on the ceiling, outlining the contour of the plinth.
  • We remove this bar and apply a striker, also rests its butt against the wall. We outline the line.
  • The point of intersection of the marked lines will be the mark at which the skirting board needs to be cut.
  • Again, we apply each bar in turn and mark the cutting point on them.
  • We draw the line from this point to the second edge of the plinth.

We cut off the skirting boards along the outlined lines, join them and apply them to the installation site. Please note that this method is easier to cut inside corners.

How to cut a ceiling plinth using a miter box template

Something resembling a miter box can be done by applying the desired cut angles to paper, cardboard or wood. Draw two parallel mowing lines, locate the center, and then use a protractor to set the desired angles. The advantage of this method is that you can postpone any angle, including more than 90 degrees. Of course, before cutting the corners of the ceiling plinth, you must first check the angle between the walls using a corner and measure with a protractor.

The technique of cutting a ceiling plinth using a miter box drawn is exactly the same as using the miter box itself. The plinth plank is pressed against one of the parallel lines, then we set the hacksaw at the desired angle, which is already outlined, and cut off.

How to cut a corner of a ceiling plinth using a miter box

The miter box is a simple carpentry tool that allows you to cut the workpiece at the desired angle. Most often it is a tray made of plastic, wood or metal with vertical slots for cutting at an angle of 90 ° and 45 °. There are also more complex miter box designs. for cutting at angles of 90, 60 and 45 degrees. For more professional work, a miter box with a swivel mechanism is used, where the hacksaw can be fixed at any angle to the workpiece.

How to cut a skirting board with a miter box. inner corner:

  • We apply the plinth to the ceiling, measuring the required length.
  • Then Install the plinth strip in the miter box so that the position coincides with the position of the plinth on the ceiling.
  • The plinth strip must be pressed against the far wall of the miter box.
  • Hold the plinth with your left hand.
  • We choose such a position of the hacksaw when the angle is 45 degrees and the handle of the hacksaw is as close as possible to the left hand.
  • We cut the workpiece, and without making excessive pressure on the saw.
  • The next step is to trim the plinth striker. We also install it to the far wall of the miter box.
  • Presses and holds with the right hand.
  • We choose such a position for the hacksaw when the angle is 45 degrees and the handle of the hacksaw approaches the right hand.
  • Cut off the skirting board.

Next, we join the trimmed plinths and check the cutting accuracy. For a more accurate orientation, they also say that to complete the inner corner, it is necessary to start cutting from the front of the skirting board. After cutting, wooden skirting boards will most likely have to be adjusted with a file.

How to cut a skirting board with a miter box. outside corner:

  • In order not to be mistaken with the dimensions, it is better to start by marking the inner corner, and then cut out the outer corner. Otherwise, a situation is possible when the bar may not be enough in length.
  • You must attach the plank to the ceiling and tent dimensions.
  • Install the plinth strip and press it against the nearest wall.
  • Hold it with your left hand and choose a position for the hacksaw at an angle of 45 degrees, when the handle approaches the left hand.
  • Cut off the workpiece.
  • Install the striker to the nearest wall, hold it with your right hand.
  • We set the hacksaw at a 45 degree angle when the handle approaches the right hand.
  • Cut off the workpiece and join the corner.

Trimming the workpiece with a miter box is suitable only if the angle between the walls of the bumps is 90 degrees. If the accuracy is poor, you will have to use other methods.

DIY impromptu miter box

Making a miter box with your own hands is also not difficult.

You will need three wooden planks or boards, which must be put together in a U-shaped box. Then the required angles are marked on the walls of the box, and a cut is made with a hacksaw. In total, you should get a wooden miter box in which grooves are cut.

A combination of an impromptu miter box and a template with marked lines. For the convenience of cutting, it is necessary to build something in which it will be convenient to hold the plinth plinth, since it is difficult to keep it suspended. Enough to put together a corner from two wooden planks or boards. On paper, you need to draw a mowing line with angles for cutting at 45 degrees or at any other. Then we apply the skirting board blank to the corner, presses it by hand, as described in the technology of using a miter box, a piece of paper with a template is moved under the edge where we are going to cut, and Cut it off. In the process of cutting, we focus on the line drawn on the paper.

As an impromptu miter box, you can use anything, anything. That forming an angle. For example, a table pushed against a wall.

It is NOT worth fixing the plinths of the ceiling plinths to how you cut the striker and tried on their location. Only after the two strikers are perfectly aligned in the corner, you can start attaching them to the ceiling. Minor flaws can be finished with a file or a nail file in the case of wooden and polyurethane skirting boards. To fit foam products, you will have to wield a sharp knife.

If suddenly, even after adjusting the skirting boards, a small gap remains between them, do not despair, it can be repaired with putty. Cutting the ceiling plinth yourself is not difficult. But in order not to spoil many products, it is better to pre-train on small blanks.

Cutting method with miter box

The most popular mounting option is with the introduction of household tools. The miter box is a renowned carpenter’s assistant helping to cut at the right angle. This is usually a tray, wood or plastic, with vertical slots for the blade at 45 and 90 degrees. How to cut the corners of a ceiling plinth with a miter box?

First, you should attach the material to the ceiling, install its bar in the miter box. In this case, the tool must match the position of the product. Holding the plinth with your left hand, choose a position for the cutting tool (hacksaw) at an angle of 45 degrees. The material is cut without undue pressure. After that, the striker is cut, set to the far wall of the wort.

Holding the working material with the right hand, select the position of the hacksaw at 45 degrees and cut.

Angle slicing

How to cut ceiling skirting boards in the corners? The secret of a high-quality incision is in making cuts both on the outside and on the inside. The inner cut matters if we make the outer corner.

Usually they use professional equipment. miter saws or industrial electric rotary hammers. But home renovation advocates can get by with conventional tools. The main requirement is that at the end of the work, the result should be a clearly visible texture for the cornice, reflected on its front or back side.

Corner slicing technology

So, at what angle to cut the ceiling plinth and where does the formation of an angle begin with the help of home remedies??

First you need to measure the angle, which is between the walls. for this you can take pieces of foam from technology. Usually the angle is 90 degrees. a strict perpendicular. In this case, trim the edges of the product at an angle of 45 degrees. Perform similar actions with the second segment.

In the event of irregularities and mismatched joints in the gap between the ceiling and walls, you need to divide the corner radius in half. In this case, do not confuse the details. The baguette for the left side is notched, and the one on the right is the other way around.

Before cutting the ceiling plinths in the corners, form a corner inside the material in the upper space. this decision is based on the fact that the lower side protrudes above the upper one. When performing an outer corner, the procedure is reversed. The texture of polystyrene foam materials itself helps to smoothly and accurately fit the details. If wooden or plastic elements are used for the baguette, then you will have to work with them more carefully.

How to cut ceiling plinths in corners with and without a miter box?

November 11, 2015

The procedure for installing fillets on the ceiling seems quite easy, but it requires specific techniques to successfully complete the repair. Often we cut the corners of the ceiling plinth completely wrong, which leads to a reduction in its service life and a number of quality repairs. Correct joining, evenly fixed edges. the result is quite achievable if you use the recommendations of experienced specialists.

Installation of finishing: features

Many owners of houses and apartments are often puzzled by the question of how to properly cut the ceiling plinth in the corners in the midst of renovation work. The problem is that it is not technically possible to make an incision at a 45 degree angle. To perform such manipulations, it is important to correctly dock at the boundaries of the outer and inner corners of the web, which is quite problematic.

The specificity of the ceiling version is not only in the vertical position of the canvas. The mount is placed at the base at an angle of 38 to 45 degrees. The difficulty lies in the implementation of the incision at 45 degrees. It is difficult to connect cut edges from the inside, gaps appear between them, aesthetics are disturbed.

For the most accurate cutting, a special corner element is used, which is inserted into the edge of the skirting board. it will help to hide the cutting errors. This element will emphasize the corners in the room, the choice of such a detail must be approached responsibly.

How To Cut A Ceiling Plinth Without A Miter Box

The skirting boards and the difficulty of cutting corners

A practical decorative element. a skirting board or fillet. can be made from:

  • Polyvinyl chloride. the most affordable;
  • Expanded polystyrene. have a low cost;
  • Polyurethane. are much more expensive than others;
  • Polystyrene. they are slightly more expensive than expanded polystyrene and polyvinyl chloride.

The wooden fillet is very popular, giving the interior a strict elegance. To make a corner cut on a wooden baseboard, use a fine-toothed hacksaw or a metal hacksaw.

Advice! If a moisture-resistant and durable ceiling plinth is required, then a polyurethane fillet should be chosen. It is important to remember that it does NOT tolerate sudden temperature fluctuations at all. it deforms quickly, therefore it is not suitable for use in the interior of the kitchen.

Each of the materials used to make skirting boards has its own advantages and disadvantages. For example, polystyrene and expanded polystyrene. they break easily, polyvinyl chloride have increased electrostaticity.

Regardless of the material from which the skirting board is made, cutting it into corners has its own difficulties, since the walls of the room do not always have exactly 90 ° angles. Sometimes, especially in old buildings, the walls can have an angle of 88 ° or 92 °, therefore, cutting the plinth at an angle of 45 °, when joining, you will definitely get a gap. To avoid this, use the presented method.

Before gluing the skirting board, check if there is a gap in the corners

Cut off the outer corners with a miter box

  • Attach the skirting board to the corner and mark with a pencil where the outer corner begins on the skirting board.
  • Then the plinth is placed in the miter box. The side that will be attached to the ceiling is laid on the bottom with a miter box, and the other side Press against the wall.
    The mark on the skirting board should be located near the left slots. Cutting off one end.
  • Then, in the same way, cutting off the other half of the corner. Only the mark on the skirting board should be located near the right slots.

We apply both halves to the corner and check if there is a gap. If everything is in order, then you can glue the skirting board in place.

Features of cutting ceiling plinths in a miter box

It is necessary to work with this device extremely carefully so as not to blunt the tool and leave no cuts in unnecessary places. In the process, we adhere to the following instructions:

    We fix the baguette in the miter box in the same way as it is planned to place it on the wall. The side that will press against the ceiling on the miter box should lie against the sidewall.

We insert a cutting tool (hacksaw or knife) into the desired gap and cut the fillet.

  • We process the joint of the ceiling plinth and apply it to the wall to check the correctness. The foam molding can be tweaked with a sharp knife if the roughness of the end is about 2 mm. The wooden skirting board can be simply sanded with sandpaper. For ease of use, it can be glued to a wooden block.
  • Technique for cutting ceiling skirting boards

    This method can be used if your corners are even and you want to trim the baguette exactly 45 degrees. To do this, before cutting the ceiling plinth in the corners, you need to draw a miter box on thick paper. Draw two parallel mowing lines and mark the angles at the desired degrees using a protractor.

    Placing the fillet in this case in the same way as in the traditional miter box. Please note that you need to cut the skirting board holding the tool in a strictly vertical position.

    Rules for cutting ceiling plinths by marking

    This method is used to cut skirting boards in cases where there is neither a miter box nor parts from which it can be made.

    To do this, you need to make markings on the wall in this order:

      We put the baguette in the corner to the place of fastening.

    Along its one edge, we draw the base line on the ceiling for the level of attachment.

    We apply the fillet in the same way to the perpendicularly drawn mowing line on the ceiling and again draw a straight line along one side. We should have two segments, which intersect at one point.

    We again apply two plinths in turn and mark this point on them.

    We repeat the same procedure now on the wall to mark on the products the place of cutting from below.

    We connect two points with a line. It can run at an angle of 38-45 degrees, since walls and corners in living rooms are often uneven.

  • Cut off the baguette along the mowing line.
  • Method of cutting the ceiling plinth without miter box

    To neatly dock fillets in the inner corners, you can do without a miter box.

    We carry out the work in the following order:

      We attach the end part of the baguette to the letter of paper and outline the contour of the convex side. It is more convenient to use a small piece of plinth (if any).

    Cut out the resulting template.

    We transfer the contour to the surface of the baguette with a simple pencil.

    Cut along the drawn curve.

    For fitting, one plinth is applied tightly with the end part to the wall, and then the second.

  • If there are small gaps, then they can be processed with a clerical knife or sealed Subsequently with a sealant.

  • Useful Tips
  • One of the most difficult steps in installing skirting boards is cutting them correctly. Only by correctly joining the individual elements at the outer and inner corners will you get the desired result. Fillets will look aesthetically pleasing and neat if you cut them off at the right angle and seal the cracks. A special tool (miter box) is used to accomplish this task. And if it is not, then other devices will help.

    Cutting technology for ceiling plinths

    For efficient and high-quality work, you need to choose a tool in accordance with the material of the baseboard and choose a cutting method. If you have a miter box, then there will be NO special difficulties in the process. If it is not there, then two options are possible: cut according to a template and measure on the ceiling or make this tool yourself.

    Selection of tools for cutting ceiling skirting boards

    To properly and accurately cut the skirting board, you need to use a suitable cutting tool. It is chosen depending on the material from which the fillets are made:

      Styrofoam. It is characterized by low strength and is inexpensive, and then foam models become more and more popular. Their strength does not particularly affect the performance, since usually the ceiling plinth is NOT subjected to mechanical stress. A regular stationery knife is suitable for cutting.

    Extruded polystyrene foam. A cheap material with a density several times higher than that of foam. Because of this, cutting it is a little more difficult, and then a sharp and thin knife is used for THESE purposes.

  • Tree. Such skirting boards are more difficult to process, although they have many advantages (environmental friendliness, strength). They are more expensive,
    especially if made of hardwood. Before cutting wood ceiling plinths, stock up on a hacksaw.
  • In addition to the tool for direct cutting of the baguette, you will need a miter box. This is a special device made of wood, plastic or metal in the form of a box with sawed off the sides. A hacksaw or knife can be inserted into it at the desired angle. Thus, the cutting angle is as accurate as possible.

      We knock three planks of 5015 cm with a long edge into the shape of a three-sided, rectangular box. Please note that an angle of 90 degrees must be respected between the side rails and the transverse board.

    Using a protractor, mark an angle of 45 degrees on the bars. Instead of a protractor, you can use a school square. In it, one angle is 90 degrees, and the other two are 45.

  • Before cutting corners, mark the vertical direction with a simple pencil.
  • Tips for cutting ceiling plinths

    When working with a miter box, there are two things to consider:

      The inner corner of the ceiling plinth is formed from two parts: the first we start the case in the miter box and cut from right to left, the second we start from the left and cut from left to right.

  • We start the first part of the outer corner from the left and cut off from right to left, the second we start the case and cut off from left to right.

    In addition, you need to know the following nuances before cutting the skirting board:

      Before you start cutting a baguette with a miter box, try cutting a test strip to avoid mistakes.

    You can make the correct measurements by measuring the length of the inner corners of the plank on the inner side, and the outer ones. these are the points of the inner corner for the width of the fillet deep into the room.

    If the baguette is installed under a stretch ceiling, then it should only be attached to the wall. The adhesive composition should never get onto the vinyl sheet.

    The final fixing of the skirting board should be carried out only after the exact fit of the plank.

    If the corners and walls in the room are even, then you can customize it on the floor.

    When installing baguettes, it may be necessary to adjust them several times, therefore, stock up on tools and patience.

    Instead of a template and a miter box, you can cut in the corner between the wall and floor, or by moving the table against the wall. In this case, on the wall, ceiling and bug, you need to mark the cutting angle of the end.

    If you are interested in the question of how to cut a ceiling plinth without a miter box, and you do not have time to use templates, then you can purchase special corner inserts in advance. They will hide the gaps, but will protrude and stand out on the coating.

    If you have a skirting board made of precious wood, then you need to cut and install it very carefully, since a large amount of putty for sealing the joints will be too noticeable, and painting over the baguette is an inappropriate solution, because this way you will hide the natural texture of the solid wood.

    Expanded polystyrene products do not have to fit close to each other due to the soft texture, but wooden and plastic models must be well docked.

  • If the trapezoidal niches on the wall need to be bypassed from above with a plinth, then we join the walls at an angle different from the straight.
    In this case, cut off the plinth at an angle equal to half the joint. For example, if the walls are joined at an angle of 120 degrees, then we cut the fillet at an angle of 60 degrees.
  • How to cut a ceiling plinth. look at:

    Outer corner

    It is most correct to observe the dimensions more accurately, first begin to mark the inner corner, and only after that does it move on to the outer.

    Otherwise, it may happen that the entire length of the bar is insufficient.

    The plank is applied to the ceiling, basting is made to size. Holding on with the left hand, the ceiling plinth is pressed against the very near wall, the hacksaw handle comes closer to the hand. The workpiece is cut.

    The strike plate is pressed against the nearest wall, while holding it with the right hand. The blade of the hacksaw should be at an angle of 45 °, the handle of the tool comes close to the hand of the master. A piece of the workpiece is cut off, the corner will neatly fit.

    Such processing with the edge of parts with wort is good in cases where the angle between the walls is even and straight (90 °).

    If its characteristics leave much to be desired, then it is worth using another method.

    Ceiling markings

    In all other respects, using this method, you will be able to cut the tent angle even more accurately than other.

    When the skirting board is applied to the intended installation location, all dimensional deviations and inaccuracies are noticeable and immediately taken into account.

    Fillet trimming

    Factory ready corners

    Note that each master has the opportunity NOT to pore over precise cutting and fitting corners.

    It is enough to measure the required length of the workpiece and cut it at right angles.

    All defects and flaws will be hidden by this special element. But it is not always possible to use such a convenient method, since the standard dimensions of such factory corners can differ markedly from the size of the plinth itself.

    Such angles will stand out for their disproportion, and it will not look very neat. But if the design of the room and the size of the blanks allow you to use this method, then you should not neglect it.

    For those who have to use one of the methods of trimming the ceiling plinth, the following tips will come in handy.

    Cutting the ceiling plinth in the corners at home without a miter box correctly: Overview

    A ceiling skirting board is a narrow decorative demarcation between the ceiling and the adjacent walls.

    It is very convenient for them to mask the joints on the walls and on the ceiling, especially if they have a different structure and are NOT made too neatly.

    Its presence makes the design of the room clearer and more complete.

    Often people ask themselves the question: how competently and neatly the room is separated with a ceiling plinth?

    This is especially true for those cases when the owner of the house prefers repairs done with his own hands.

    Corner trim

    First you need to take a couple of blanks, then cut them at right angles. Supports the end of the plank against the perpendicular wall, apply one plank. Trace the line on the ceiling along the contour of the baseboard. We remove the first bar, then, in the same way, the butt rests against the wall, we apply the counter bar. In the same way, mark the line along the contour.

    The point of intersection of the two SEPARATE lines is the elevation at which the workpiece is cut. Each strip is applied to the surface again, on both the point of the future cut is marked. Here is the found point to the second edge of the plinth strip, line the line. Cutting the skirting boards according to the previously made outlines, carefully join them, place them in the place of their installation.

    This method allows you to more accurately handle the inner corners.

    How to cut a skirting board without a miter box? How to make a template with a miter box with your own hands

    If you don’t have a miter box, you don’t necessarily need to buy a one-time tool. You can make a template with similar functions yourself.

    To do this, the required cut angles are applied to wood, paper or cardboard.

    Then you need to draw a pair of parallel lines, find the center, and then use the protractor to measure the angles of any given value.

    This method is especially convenient because, using it, you can postpone an angle of any magnitude, even more than a straight line.

    The method of processing a skirting board using a homemade tool is practically the same as working with the original. The bar is pressed against one of the parallels, after which the hacksaw is set at the required angle and cut off.

    Ceiling plinth. fillet

    To do this correctly, it is important to strictly follow the existing recommendations and rules for finishing work. And then the result will please you.

    In order to hang the ceiling plinth, even inexperienced repairmen do not have any difficulties. They are worried about something completely different: how to cut the ceiling plinth correctly? In fact, almost every room, no matter how intricate shape it is, is equipped with corners.

    And in THESE inner corners, the individual elements of the plinth must be nicely and evenly joined. And in rooms of a particularly complex configuration, you will have to be wise and over the outer corners. Let’s try to figure out how to be in each of THESE situations, and how to cut the desired part using the available tools.
