How to cut the outer corner of a ceiling plinth

How to cut a ceiling plinth: work with or without a tool

Any repair requires attention to the smallest detail. On how well the finish is made, depends on the appearance of the room and its overall perception. To a greater extent, this applies to ceilings, which in most cases are not perfect, so to hide all the imperfections (their and the walls), many owners use ceiling skirting boards, which give the rooms completeness. If the installation of the baguettes in straight areas does not cause any special difficulties, then the joints of the elements in the corners require maximum accuracy. Therefore, many owners who are planning, or have already begun repairs, are interested in how to cut the ceiling plinth, what tools can be used for this stage of the work.

The answer to the question of how to cut a ceiling plinth, depends on the material from which it is made. Slicing is different because the baguettes have different densities. Therefore, the first thing to consider is the most popular materials, and at the same time the peculiarities of their cutting.

Foam

These products have the lowest price, because the material is very unstable to mechanical influences. Styrofoam is easily scratched, damaged by accidental impact. Pluses. minimum weight, which simplifies gluing, easy processing, the ability to paint in any color.

This foam material consists of small granules, which are quite easy to separate from each other. However, they are the main disadvantage of such baguettes. They require a very sharp tool. Otherwise, the skirting board can crumble, so it will be unsuitable for installation. This is true for both angular and straight cuts.

Styrofoam

This contender is more expensive, but it does not differ from the first candidate very much, because it is a “relative” of foam: it is produced from expanded polystyrene. This material also consists of small granule bubbles, but they stick together more densely. But also polystyrene foam will not tolerate not too sharp blade, it also crumbles. Therefore, the master needs to prepare no less than a sharp tool.

The main advantage of foam and polystyrene foam is their softness, which avoids the appearance of gaps, tightly pressed pieces to each other and to the corners.

Extruded polystyrene foam

EPPS is produced from the same raw materials as conventional polystyrene foam, but in this case using a different, more sophisticated technology. Ordinary EPS is made with the help of steam, which is passed through the microgranules.

To obtain extruded polystyrene foam, the particles are mixed at high temperature and the same pressure, and then in the raw material is added foaming agent. The size of the granules in this material is much smaller (maximum 0,2 mm), as a result it is less crumbly and more durable. Very sharp tools are not required for its cutting, but bluntness of the cutting edge is also not welcomed.

Polyvinyl chloride

Plastic skirting boards (PVC). another type of ceiling products. Usually they are purchased for finishing bathrooms. If we consider the topic “How to cut a ceiling plinth”, in this case they are exceptions, because they use special, ready-made corners to dock them.

In general, these baguettes can be cut with a box cutter, a metal hacksaw, or a sharp kitchen tool. Since PVC products do not restore their shape due to the lack of elasticity, it is not recommended to put a lot of pressure on them when cutting.

Polyurethane

This is another representative of polymer products. It is characterized by high density and lack of disadvantages of previous competitors. It is easy to cut, so the tool must be sharp, but there are no maximum requirements for its sharpening. Baseboards made of polyurethane do not crumble, do not warp, and can withstand almost any pressure with honor.

Wood

This traditional material is cut with the usual carpentry tools: for example, a jigsaw, hand or electric. The places of the cut should be treated with sandpaper or a file. Since such products are more expensive than other skirting boards, care is required in the work. A serious mistake can be made easily, but there is no way to fix it. The consequence of carelessness will be the purchase of a new baguette.

The ideal tool for cutting wooden workpieces would be an electric mitre saw. The biggest disadvantage of it. the high price, especially quality models. On the other hand, buyers have the opportunity to find an inexpensive tool that will do the job decently.

Used tools

First about how to cut a polymer or wooden ceiling plinth, how to do it correctly and quickly. In this case, the work will require 2 tools. a plane and a cutting tool.

What to cut baseboards with?

As for the latter, the choice depends on the baseboard material:

  • products from foam plastic (all polystyrene) assume the use of a sharp office knife;
  • Skirting boards from polyurethane are usually cut with a metal saw;
  • Wood requires a jigsaw or saw to be actively involved.

The second potential tool for polyurethane is the same office knife. The reason is the rather low density of the material. Another alternative is a sharply sharpened kitchen knife. A special requirement for it is not too thick a blade.

A possible substitute for a wood jigsaw. a hacksaw for metal. The blade with the smallest serrations is optimal. Otherwise, the tool will get stuck in the material, and in such conditions it is extremely difficult to make a flawless cut.

The mortiser and its self-made construction

Chisel. the second indispensable tool for working with baseboards.

What is it?

Not everyone may know what it is. This is a device that allows you to cut any workpiece at different angles (45-90°). This is a chute consisting of a bottom and two sides in which slots are made for tools. At the bottom of it lay the material, and in the slots are inserted a hacksaw (knife, etc. д.). After sawing the baguettes with it you get almost perfect blanks.

Chisel. a necessity for trimming any skirting boards, because the joints of the elements require an angle of 45°. Otherwise, the connection of parts will not work: or there will be a gap between the adjacent skirting boards, or they will simply need to be trimmed again, because it will be impossible to dock the adjacent products.

Yes, the remaining hole can be masked with a compound. However, this option is still not the best. The filler may soon change color a little, and this discrepancy will become very noticeable. However, even here there is an exception.

How to make a jigsaw?

For self-made, you will need to find a board length of about a meter or more, or a sheet of plywood (chipboard). Still need to prepare:

  • From the selected material cut out 3 parts with a width of 200 to 250 mm, their length. 300 mm (400, 500 mm). With the help of self-tapping screws, they are connected in the shape of the letter “U”.
  • Using a protractor, the upper parts of the sides make marks corresponding to the angle of 45 ° (if necessary, and 90 °).
  • Then they take a hacksaw, which saw holes so that the grooves reached the bottom of the tool.

Finished holes are reamed with a rasp, so that a jigsaw or hacksaw could freely enter into them.

Cutting with a power wire: the outside corner

Most often, when installing ceiling plinths home craftsmen are interested in how to formalize the inner corners of the room. Cutting exterior corners is less common, but with a certain wall layout and it is necessary. Consider how to properly make the inside of the fillet, using a special tool (the plough).

First you need to buy a chair. This tool is a tray in which the part is fixed, and it is trimmed. In order to measure the length of the necessary product, you need to put it to the ceiling. Further, it is necessary to establish a plinth in a chair. Its location should correspond to the position it will occupy on the ceiling.

Plinth

Important! While cutting it is necessary to hold the left hand to the fillet. It must fit tightly against the wall of the tool. The part of the product, which will be fixed to the ceiling, must be at the top. The other part is pressed tightly to the bottom of the working tool.

How to properly cut the inside corner of the ceiling plinth. a difficult question, to answer which helps to appropriate photos. Specialists recommend studying them, and only then begin the work.

Once you are satisfied that the product is positioned correctly in the tool, you can start cutting. The hacksaw must have a certain angle, viz: 45 degrees. It is not recommended to apply too much pressure on the cutting tool during the work, because it can damage the surface of the chisel. Then the trimming of the adjacent fillet is performed, which is done in a “mirror” way.

Cutting with a power hacksaw: inside corner

To get the right inside angle, it is best to use a professional tool. Such work can of course also be carried out without the chisel, but then more effort would be required. Consider the sequence of operations for cutting an inside corner with the jigsaw.

The first thing to do is to determine the distance from the corner on the outside to the nearest wall. Next, it will be necessary to mark the baseboard, thus preparing it for cutting. On the outer side of the bar, you need to draw the line for the trimmer along the length of the measurement. It is worth noting that in this case, the upper part of the die must protrude slightly.

After that, you can start trimming. To do this, the ceiling plinth is placed in the cutting tool and pressed firmly against the wall. After the first piece has been cut, the counter piece can be cut.

What tools do you need?

The following tools may be useful for the ceiling plinth, depending on the chosen method of work:

  • Wood saw. Useful for working with wooden ceiling skirting boards.
  • Metal blade. Suitable for other types of baseboards (foam, plastic, etc. д.).
  • Chisel. The tool is a groove, which has the shape of an inverted U, where at angles of 45° and 90° lines are marked for the kerf.
  • Using an electric mitre saw. Can be used instead of a chisel to achieve a precise cut.
  • Electric jigsaw. Easy to operate, with it you can qualitatively and correctly cut the corner without a burr.
  • A office knife or a construction knife. Suitable for skirting boards made of polystyrene, it is important that it has an excellent cutting blade, and therefore it must be well sharpened.

How to make a smooth corner: ways

The most difficult thing to cut a corner so as to get a perfectly flat: the surface of the materials used is not easy to cut, in addition, you need to maintain a good docking, preferably without huge gaps. How to make a corner on a ceiling plinth? There are several ways: with a ruler, without a ruler, with decorative angle, and also an alternative method.

How to cut a skirting board without a joiner? To work you will need a well-sharpened pencil, a small piece of baseboard, a box cutter (for polystyrene or polyurethane) or a metal saw (for other materials), a ruler.

You need to attach the baseboard to the corner and draw the trimmer line with a pencil along the outer edge, then attach it to the other side of the corner and also mark. As a result, on the ceiling will be a cross, the center of which will mark the place where the planks of the ceiling plinth should converge.

Position a piece of the skirting board where you will glue it. Having set it in the wall by its end, transfer the necessary mark to it. You can cut the ceiling skirting boards corners this way, without the jigsaw.

How to cut a skirting board without a joiner

Suppose you have an urgent need to glue a ceiling skirting board.

How to make a corner without a joiner? This is possible, although it will take more time. Proceed as follows.

  • Both parts of the skirting board must first be trimmed at a right angle.
  • Mark the position of the elements on the wall and apply a fishing line to trimmer their junction. As a result, we will see two intersecting lines. The point of their intersection is projected directly onto the skirting details.
  • Place the skirting board on the ceiling and trim the cut from one edge to the other with a fishing line.
  • Finishing of details is carried out with a stationery knife or a construction knife.
  • A virtual jigsaw is drawn on the paper, with lines drawn at the right angles. The baseboard tile is attached to such a stool and the cut is performed (with the blade of the knife should be kept vertical).

Tip! Since it is not always the ideal shape of the inner or outer corner, the ceiling skirting will have noticeable gaps in the joints.

To make them less noticeable, plaster putty should be applied to the ends of the skirting boards before gluing them. After joining the elements unnecessary putty removed with a rubber putty knife. All gaps will be filled and the joint will be less noticeable.

It is not easy to glue and properly dock the skirting boards with the pattern. What to do in such a case? The answer will prompt video.

Docking the baseboard with decorative corners

In the case where the walls are perfectly prepared, and external and internal angles are equal to 90 °, you can use special decorative elements for joining the baseboard trim. The advantages of this method:

  • Ease of installation: no need to “teach yourself” by perfecting the technique of trimming parts of the skirting boards;
  • saving time: to join the elements you just need to cut them at right angles and attach the decorative part.

The decorative parts themselves are designed to join the skirting boards:

This method of connection is the only option in the case of installation of plastic skirting boards, which can not be trimmed without gaps.

Material of manufacture and name

The first material from which began to produce skirting boards for ceiling design, was plaster. They had to be cast in special forms, after which they were attached to the ceiling with a plaster mortar. Such elements of the decor were called battens and nowadays they are practically not used, and you can see them in old houses, which have hardly survived during this time. These are expensive elements of interior decoration, so no one uses them today, and their name is almost unknown to anyone. To date, there are cheaper and more practical skirting boards for finishing ceilings.

Part of the range in the specialized store

Nowadays, ceiling skirting boards are made of materials such as polystyrene or polyurethane. These are inexpensive decorative elements, which have a number of other advantages associated with ease of installation, with practicality and attractiveness, as well as “weightlessness”, compared to the elements of finishing from plaster, which have an impressive weight. Such plinths from polyurethane or polystyrene are made of various widths (from 5 to 250 mm), and also have a wide range of forms and drawings, so there is an opportunity to pick up such decorative elements for any style of decoration. The only exception are the wooden buildings, designed in the appropriate style, where the basis is taken from wood elements and here it can not be helped, because the style always dictates its own terms.

There are also plastic skirting boards, which are not afraid of moisture, so they are used for finishing rooms with high humidity. At the same time, it should be noted that polystyrene decorative elements are also not afraid of moisture.

Trim ceiling skirting boards in the corners with some methods, while these options are not suitable for trimming plastic skirting boards.

Tools to use

Depending on the manufacturing material, for trimming baseboards used different tools: when working with wood baseboards used hacksaw for wood, and when working with plastic or polyurethane baseboards is better to use a hacksaw for metal. The elements of a decor from foam plastic are easily cut by usual, sharp office knife. In most cases, a wire cutter is used, allowing a precise cut of the skirting boards at a certain angle. If you use a hacksaw for metal, you should not press too hard, as the cut may not be smooth, with burrs, and the material can crumple and lead to disrepair. Polystyrene and polyurethane skirting boards need to be handled with care.

If there is no experience with such tools, as well as decorative elements, it is better to take a small piece of finishing material and practice with different force of pressure, which will further help in solving the problem.

How to cut a corner with the chair

Chisel. carpentry tool, with which you can cut any material at an angle of 45 and 90 degrees. The mortar can be made of wood, plastic or iron. Even in the simplest device there are openings for a hacksaw, the more expensive models even have a rotary mechanism.

The principle of the jigsaw is very simple. Place the slat in the groove, press it down and cut through the side holes. The end result is a cut at the right angle.

  • Take measurements.
  • Put the skirting board face up in the groove of the wood skating rink.
  • Press down the slat with your hand, but not too hard (if the skirting board is made of foam plastic, it can easily be broken).
  • Insert a hacksaw at a 45-degree angle into the opening of the woodworking machine, and make the cut
  • In a mirror reflection, cut the second piece in a similar way. The inner corner is formed.

Tip:! It is possible to cut a skirting board with a metal hacksaw, but if the baguette is narrow, it is better to use a construction knife, it makes the cut more even.

Cut the outer corner just as easily. Step by step instructions:

  • On the wrong side of a skirting board mark necessary length, but its edge should protrude a little.
  • We put a slat in the jigsaw at an angle of 45 degrees and make the cut through the holes.
  • Mirror cut the second slat.
  • Prepared elements we attach to a wall. If everything is straight, we glue, and if there are flaws, we simply remove them with a sharp knife.

If you have to work with a jigsaw for the first time, it is better to first practice on extra pieces.

How to cut an angle without a jigsaw

It is possible to cut the corner and glue the skirting boards without a joiner. Let’s tell how not to spoil the appearance of a baguette.

  • On any solid basis we draw a line for a trimmer.
  • Set back 10 cm from the line and draw another line for the trimmer.
  • At right angles draw a line through the parallels.
  • From a line on each line we do marks on 5 sm and connect by lines opposite points.
  • Lines with parallels will make a 45-degree angle as a result.
outer, corner, ceiling, plinth

In such a way we get a homemade plinth, and now it’s necessary to determine the slope and to make a cut of a skirting board.

  • We glue the skirting boards to the ceiling, and determine the direction of the cut for precise and correct installation.
  • For the inside corner, the top edge should be shorter than the bottom edge.
  • For the outside corner the top edge must be longer than the bottom edge.
  • It is necessary to cut baguettes in a mirror reflection.
  • On the skirting board, which will be located on the right, you need to make the cut on the left side. On the slat on the left side there is a slit on the right side.
  • We lay the strips on the homemade jigsaw along parallel lines and, taking into account the direction of the angle, make a cut according to the marks.

To make the cut without roughness and splinters, you need to move the knife carefully in one direction.

The first way. with the help of a plier

A professional diagonal cutter with a rotary hacksaw

The chair usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool represents the oldest and simplest carpenter’s tool, designed for cutting wooden parts at 90° and 45° angles. There are types of such a device and for professional work, with a rotating mechanism, in them the cutting tool can be rotated and fixed in any position.

How to cut a ceiling plinth

Ceiling corners are divided into interior and exterior, the method of joining them is slightly different.

If necessary, you can make a jig with your own hands. For this you will need three scraps of plywood or boards of equal size. First they are applied in the form of an inverted “U” and make a marking of the corners. Then, according to the markings, cut notches under the hacksaw almost to the bottom, and the boards are twisted.

Inside corner

  • Making the right measurements.
  • We set the baseboard plank in the jig so that this position coincides exactly with the placement on the ceiling.
  • The skirting board must be pressed tightly against the opposite wall of the jigsaw. Hold it and press with your free hand.
  • Put the hacksaw at a 45° angle in the special hole and cut the piece.

When cutting soft materials (PVC, Styrofoam) use a metal hacksaw or a regular construction knife. Then the work will be neat and with straight edges.

Outer corner

  • Measure the length of the skirting board from the nearest wall to the outer corner, leave a trimmer fishing line on the wrong side of the wall with a pencil, marking the desired length. Please note that the edge (its upper part) must protrude slightly outwards.
  • The skirting board is moved to the jig and cut off.
  • The adjacent plank, too, must be measured with a margin and cut in a mirror reflection to the first part.

Trying on a skirting board: the joining of parts should be perfectly straight. If the result is not achieved and the joints are uneven, you can trim the edges with an ordinary knife until the perfect junction.

The second method. without additional tools

For the inside corner, you can use the easiest way to perfect the joint. by marking on the ceiling. Another example of how to cut a corner nice and flat.

The end result is an even 45° angle if you run a trimmer line from the intersection point to the edge of the part. Note that the above method of marking works only if the corners are perfectly straight.

Trimming the corner

Trimming with a mitre cutter

How to evenly trim the corner of the ceiling plinth with it?

A chainsaw is a simple tool that carpenters use. With its help, you can cut any workpiece at the desired angle.

It is usually a wooden, metal or plastic tray, which are made to cut at an angle of 45 ° and 90 ° special vertical slots.

There are complicated designs, which in addition to the named angles also have a hole to make a 60-degree cut.

For professional work, a special plane is available. Its rotating mechanism allows fixing the cutting blade in relation to the workpiece at any given angle.

Inner corner

The prepared skirting board is applied to the ceiling, the required length is set aside.

Then this same slat is inserted into the jig exactly as it will be positioned on the ceiling. It must be pressed against the far wall of the fixture. The skirting board is held in this position by the left hand.

the saw blade should be at an angle of 45 degrees with the handle as close as possible to your hand. Trying to avoid exerting pressure on the saw, we carefully cut the workpiece.

Further it is necessary to cut a mating strip from a plinth. It is also placed at the far side of the tool, held and pressed down, this time with the right hand.

Similar position to the previous procedure. its handle is close to the hand at an angle of 45 degrees. The skirting board is cut.

Then the finished, already trimmed strips are docked. the accuracy of fit is checked. It is believed that for better orientation, when making an inside corner, it is better to start cutting from the front part of the product. The places of cuts usually have to be further adjusted with a file.

Outer angle

It is right, in order to keep the dimensions more accurately, to start with the inside corner first, and only then move on to the outside corner.

Otherwise, it could happen that the entire length of the strip is not enough.

The plank is attached to the ceiling, according to the size are made marks. Holding the left hand, the ceiling plinth is pressed to the closest wall, the handle of the hacksaw is close to the hand. The workpiece is cut off.

The response strip 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 is close to the hand of the master. A piece of the workpiece is cut, the corner is neatly docked.

Such a processing of the edge of the parts with the wort is good if the angle between the walls is flat and straight (90 °).

But if it is not so good, you must use another method.

Marking on the ceiling

The method with the marking on the ceiling allows you to cut a corner exactly and straight. It has one disadvantage. it’s quite inconvenient to hold the baseboard by weight during the procedure.

In all other respects, you can use this method to estimate the angle even more accurately than other methods.

outer, corner, ceiling, plinth

When the plinth is attached to the proposed place of installation, all size deviations and inaccuracies are visible and immediately taken into account.

Cutting a corner

First take a pair of blanks, then cut them at right angles. Perpendicular to the wall, against the end of the skirting board, we attach one slat. We draw a trimmer line on the ceiling, following the contour of the skirting board. We remove the first skirting board, then in the same way we press the end face to the wall and attach the counter skirting board. Exactly the same way mark on the contour of the trimmer line.

The intersection point of the two separate lines is the mark at which the workpiece is cut. Each slat is placed against the surface again, and the point of the future cut is marked on both slats. From the point found to other edge of a plinth plank draw a line for a trimmer. Baseboards are cut on marks made earlier, accurately we juxtapose, we place in a place of their installation.

This method allows you to handle inside corners more accurately.

How to cut a ceiling plinth correctly. Important Details

Measurements needed to trim the skirting boards on the ceiling, should be made in a special way. To determine and mark the inside corner, the length should be measured from the corner. To mark an outer corner, be sure to take into account that the skirting board will protrude into the interior of the room at a distance equal to its width.

It is not desirable to fix the skirting boards before their precise positioning has been tested and the mating skirting has been cut. Only when the two skirting boards are perfectly flush in the corner can they be assembled and fastened. If you work with polyurethane or wooden skirting boards, you can fix the defects and imperfections with a file or file. To fit the foam plastic product, you should arm yourself with a sharp knife.

If, even after finishing plinths remain even a small gap, do not rush to upset. it is not difficult to patch with an ordinary putty. It is not that difficult to cut a skirting board accurately and neatly. But to acquire at least a small skill, first try to practice on small blanks.
