How to cut a ceiling plinth with a wire cutter

How to cut a ceiling moulding: with or without a diagonal joint

Any repair requires attention to the smallest detail. The look and feel of the room depends on the quality of the finish work. To a greater extent this applies to the 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 baguettes in straight sections does not cause particular difficulties, the joints of the elements in the corners require maximum accuracy. Therefore, many owners who are planning, or have already started the repair, 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 what material it is made of. Cutting is different, because the baguettes have different density. Therefore, the first thing to consider is the most popular materials, and at the same time the peculiarities of their cutting.


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

This foamed material consists of small grains that can be separated quite easily. However, they are the main disadvantage of such baguettes. They require a very sharp tool. Otherwise the skirting board might crumble, so it would be unsuitable for installation. This is true both for the corner cut and the straight cut.


This contender is more expensive, but it is not very different from the first candidate, because it is a “relative” of Styrofoam: it is produced from expanded polystyrene. This material also consists of small granular bubbles, but they adhere to each other more densely. But polystyrene foam will not tolerate a blade that is not too sharp, it will also crumble. Therefore, the master needs to prepare no less than a sharp tool of labor.

The main advantage of foam and polystyrene foam is their softness, which allows you to avoid gaps by pressing the pieces tightly to each other and to the corners.

Extruded polystyrene foam

EPS is made from the same raw materials as conventional polystyrene foam, but in this case uses a different, more advanced technology. Conventional 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 pressure, and then a foaming agent is added to the raw material. 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) is another type of ceiling product. They are usually 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 for docking.

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


This is another representative of polymer products. It is characterized by high density and lacks the 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 honour.


This traditional material can be cut with common carpentry tools: e.g. a jigsaw, hand or electric. The places of the cut are processed with emery paper or a file. Since such products are more expensive than other skirting boards, care is required when working. A serious mistake can be made easily, but there is no way to correct it. The consequence of negligence will be the purchase of a new baguette.

The ideal tool for cutting wood would be an electric mitre saw. Its biggest disadvantage. the high price, especially for quality models. On the other hand, customers have the opportunity to find an inexpensive tool that will do a decent job.

Tools to be used

Firstly about how to cut a polymer or wooden ceiling plinth, how to do it correctly and quickly. In this case, 2 tools are needed for the job. a plane and a cutting tool.

What to cut the baseboards?

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

  • The foam plastic products (all polystyrene) require a sharp office knife;
  • Polyurethane skirting boards are usually cut with a metal saw;
  • Wood requires a jigsaw or saw to be “active”.

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

A possible substitute for a wood jigsaw is a metal hacksaw. The blade that has the smallest serrations is optimal. Otherwise the tool would get stuck in the material, and making a perfect cut under these conditions is extremely difficult.

The chisel and making it yourself

The chisel is 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 °). It is a trough, consisting of the bottom and two sides, in which slots are made for tools. Material is placed on the bottom of it, and a hacksaw (knife, etc.) is inserted into the slots. д.). After sawing baguettes, it produces almost perfect workpieces.

The chisel is a necessity for trimming any baseboards, because a 45° angle is required for the joints of the elements. Otherwise, the connection of parts will not work: either between the adjacent skirting boards will remain a gap, or they will simply need to be trimmed again, because it will be impossible to join the neighboring products.

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

How to make a crosshair?

For self-made 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). Using self-tapping screws, they are connected in the shape of the letter “U”.
  • Using a protractor, make marks on the tops of the sides, corresponding to an angle of 45 ° (if necessary, and 90 °).
  • Then take a hacksaw and saw the holes through so that the grooves reach the bottom of the tool.

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

A few words about tools and materials

Skirting boards are now made of wood or PVC, simply put, plastic. Ceiling ties have a slightly longer list:

The range of ceiling skirting boards is much wider than the flooring direction.

  • Polyurethane. these baseboards have good elasticity and can envelop radial and other curvilinear surfaces, but they need to be trimmed under clear angles in any case;
  • Foam. the easiest budget option, the price of foam skirting boards is low and they are cut very easily;
  • PVC. the principle is the same as the floor skirting boards, but the range is much wider;
  • Wooden. similar to the floor, only here there are still wide models;
  • Gypsum. with the advent of polyurethane and foam plastic, gypsum ceiling ties have moved into the background, firstly, they are heavy, and secondly, fragile. But it’s fair to mention them.

Since the correct trimming of ceiling skirting and its floor counterpart is impossible without a good tool, we will dwell on this issue a little more in detail.

The best, almost perfect tool for trimming any baseboard or anything else is a sliding compound mitre saw with a pivoting frame. The high-speed blade makes smooth and precise cuts, and the base of these units swivels to any angle. The only problem is the serious cost of this tool.

A coping saw is excellent for trimming baseboards and more.

It is said that one of the best hand tools for accurately cutting small bars is the coping saw. In principle this is true, but I will tell you honestly, it is not easy to find a really good quality saw, even with the current range. If you do decide to buy such a tool, it is better to buy a saw with a fine tooth.

The filesaw is very handy when working with a jigsaw.

Theoretically, foam plastic and polyurethane can be cut with any sharp, durable knife. But you need to have a steady hand and at least a little experience in cutting Styrofoam. Plus, wide skirting boards with a knife is very problematic to cut.

Without experience it is very problematic to make a clean cut with a hacksaw.

Personally, in the absence of a trimmer, I use only a metal hacksaw. It is suitable for cutting absolutely any material, from Styrofoam to wood. By the way, the question is often asked what to cut the plastic plinth for the floor, so take a hacksaw for metal and you can be sure you won’t make a mistake.

For trimming baseboards, a metal hacksaw is considered one of the best tools.

How to cut a baseboard at 45 degrees

Choose a tool for shaping an angle

The most economical option. the purchase of an ordinary plastic wire cutter. It represents a plastic block with eight working slots. Such a device is designed for only two operations: trimming under 45, 90 and 22.5 degrees. A 90-degree angle is useful, for example, if you need to cut a jack in the middle of the molding.

Some tools come with eccentric locks. They are better, because it is easier to work with it. plinthsazhchajivaetsya in a suitable position does not move during the cutting. Accordingly, the errors if and will happen, then small and adjust the angle will be easy.

What to cut plastic skirting boards with: a standard plastic wire

If you have to repair in your own home, then it is ideal for you to buy a more formidable tool. a pivoting single-plane plier. It is designed for cutting at an angle of 15, 22.5, 30, 36, 45 and 90 degrees. The design of such a crosscut includes 2.4 clamps. for clamping in the horizontal and vertical planes, and the limiter, which will allow you to cut the workpiece to one length. The hacksaw here will be a built-in. If you do not understand how to cut a ceiling plintus. a video review below will help you.

How to trim a baseboard in a corner: the rotary jigsaw

How to file a ceiling plinth contains a detailed description of the rotary jigsaw, and information that, in fact, how to use this tool.

How to cut a ceiling moulding using a jigsaw template

Something reminiscent of a wire cutter is made by drawing the necessary corners of the cut on paper, cardboard or wood. It is necessary to draw two parallel lines, find the center, and at the end to set off the desired angles using a protractor. The advantage of this method will be that there is an option to defer at least any angle, including greater than 90 degrees. Naturally, before you cut the corners of the ceiling plinth, it is necessary in advance to check the angle between the walls with a corner and measure with a protractor.

The method of cutting the ceiling plinth with the drawn jigsaw is exactly the same, as well as with the jigsaw itself. The baseboard plank is pressed to one of the parallel lines, later set the hacksaw at the desired angle, which is already marked, and cut off.

How to cut the corner of a ceiling plinth with a wire cutter

Pliers. a common carpentry tool that allows you to cut the workpiece at the required angle. Almost always a tray of plastic, wood or metal with vertical slots for cutting at an angle of 90 ° and 45 °. There are also more complex designs of the crosscut saw. for cutting at angles of 90, 60 and 45 degrees. For more proficient work using the bow saw with a swiveling mechanism, where the saw blade can be fixed at any angle to the workpiece.

How to cut the ceiling skirting board with a wirejet. the inside corner:

  • We put the skirting board on the ceiling, measure a suitable length.
  • Later, set the baseboard plinth in the jig so that the position coincides with the position of the plinth on the ceiling.
  • The baseboard plank is preferably pressed against the far wall of the jigsaw.
  • Holding the skirting board with the left hand.
  • We choose the position of the hacksaw when the angle is 45 degrees and immediately the handle of the hacksaw is very close to the left hand.
  • We cut the workpiece without exerting too much pressure on the saw.
  • The next step is to trim the baseboard mating strip. Also set it against the far wall of the wood skirting boards.
  • Press it down and hold it with your right hand.
  • We choose a position for a hacksaw when the angle is 45 degrees and the handle of the hacksaw is close to the right hand.
  • Cut the skirting board.

Next, we dock the cut skirting boards and check the accuracy of the cut. For more accurate orientation they say, that in order to cut an inside corner you should start from the front part of the skirting boards. The wood skirting boards after trimming, most likely, you will need to fit with a file.

How to cut a ceiling plinth by means of a tape saw. an outside corner:

  • To not make a mistake with the size, it is better to start with the marking of the inner corner, and then cut the outer corner. Otherwise it is possible that the length of the planking might be insufficient.
  • It is necessary to put the plank to the ceiling and outline the dimensions.
  • Install the ceiling plinth trim and press it to the nearest wall.
  • Hold with the left hand and choose a position for the hacksaw at an angle of 45 degrees, when the handle is close to the left hand.
  • Let’s cut the workpiece.
  • Install the counter bar to the nearest wall, hold it with the right hand.
  • Set the hacksaw at a 45 degree angle with the handle close to the right hand.
  • We cut the preform and connect the corner.

Trimming blanks with the help of a ruler is suitable only if the angle between the walls is even. 90 degrees. In this case, the accuracy is not civilized enough, you will have to use other eyes.

Using decorative corners

We mean special corner adapters, which are usually equipped with polyurethane and polystyrene friezes. Decorative corners are glued to the very corner, and baguettes are attached to them on both sides. Trimming in this case is either not required at all, or is performed with a simple office knife.

The composition and features of the material

To understand how to correctly cut the plinth, it is necessary to understand its composition. This will help you choose the right tool and cutting technique.

  • Styrofoam. The cost and strength of this material is the lowest. But because we are creating a decorative ceiling decoration, strength is not particularly required.
  • Skirting boards made of polystyrene are more dense. than ordinary foam plastic. To cut this material a very ordinary knife is used.

Tip: Sharpen your knife well before use. This will relieve the presence of jagged edges in the areas of the cut.

Tip: The shallower and more frequent the tooth of the saw, the smoother the edges will be. You can even use a blade for metal.

Using an ordinary hacksaw blade

Chisel. a tool for cutting baseboard corners

There are two ways to cut corners. with and without the tool (chisel). We will consider both methods.

Chisel. a carpenter’s tool, which is a small rectangular tray (you can make it yourself from wood or buy ready-made from plastic or metal), in the walls of which there are grooves. Slots guide the blade of the hacksaw at a specific angle to the axis of the tray.

Important: the angle of cutting the edge of the baseboard. always oblique and equals 45 °, when processing elements designed for installation at the joint in the corners of the ceiling. The oblique cut provides a tighter fit of the fillets.

How to make a jig for the ceiling plinth with their own hands

If such a useful tool as a notch is not available, it can be replaced or made by hand.

In simple cases, for example, for cutting foam plastic, the role of the chair performs an ordinary cardboard or a sheet of heavy paper. On it set off 2 parallel segments and use a protractor to mark the planned places of the cut. Then simply put a piece of the product and cut it off, using cardboard as a template.

If the material is wide, hollow inside, or made of such a strong material like wood, it is impossible to do without a chisel or its analog. Then it goes like this.

  • On cardboard or heavy paper make a template.
  • Then, from any suitable material, make corners for the ceiling plinth. from two slats, for example. The material is inserted into the element as in a jig.
  • Then the device is placed over the stencil so that the end of the baseboard is over the drawing. Insert the profile into the substitute for the jig and cut with a knife or saw at the mark.

In this case, the blade of the knife rests only on the homemade product, so you need to be careful when working.

Selection of tools for cutting ceiling plinths

To properly and accurately cut the ceiling plinth, you need to use a suitable tool for cutting. It is chosen depending on the material from which the fillet is made:

    Styrofoam. Characterized by low strength and costs relatively inexpensive, and therefore foam models are becoming increasingly popular. Their strength does not particularly affect performance, because usually the ceiling plinth is not subjected to mechanical stress. An ordinary office knife is suitable for cutting.

It can be purchased in a construction store or make your own hands according to these instructions:

    Three 5015 cm boards nailed with a long rib in the shape of a tripartite, rectangular box. Pay attention, between the side planks and the cross plank should be observed angle of 90 degrees.

To work with this homemade device was convenient and safe, before joining the boards need to be well sanded.

Cutting technology ceiling skirting boards

For prompt and quality work, you need to select a tool in accordance with the baseboard material and choose a method of cutting. If you have a wire cutter, there will be no special difficulties in the process. If you do not have a protractor, you have two possibilities: to cut using the template and the measurements on the ceiling, or to make the tool yourself.

Features of cutting ceiling plinths in a jig

Work with this device should be extremely careful not to blunt the tool and not to leave cuts in unnecessary places. In the process, we adhere to the following instructions:

    Fix the baguette in the stool in the way you plan to place it on the wall. The side that will be pressed to the ceiling on the jigsaw should be adjacent to the sidewall.

When cutting and trimming products of foam and polyurethane remember that these materials crumble and press through, so the tools must be sufficiently sharp, and a strong mechanical effect on them is undesirable.

Technique of cutting ceiling plinths according to the template

This method can be used in that case if corners at you. are equal, and it is required to trim a molding exactly on 45 degrees. To do this, before you cut the ceiling baseboard in the corners, you need to draw a jig on heavy paper. Draw two parallel lines and mark the angles at the right degrees, using a protractor.

Place the fillet in this case in the same way as with a traditional jigsaw. Keep in mind, that you should cut the skirting boards holding the tool strictly vertically.

Rules of cutting ceiling plinths by marking

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

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

    Putting the baguette in the corner to the fixing point.

When cutting in this way, it is important to accurately draw all lines and mark points. A mistake of even a few millimeters will cause the formation of a gap. This method is suitable for cutting and joining both inside and outside corners of the ceiling plinth.

How to cut a skirting board without a chisel

To accurately join in the inner corners of the skirting boards, you can do without a pitchfork.

    We enclose the end part of the baguette to a sheet of paper and trace the contour of the convex side. It is more convenient to use a small section of the skirting board (if you have one).

The first method. using a power drill

A professional power plier with a rotary hacksaw

Chisel usually looks in the form of 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 an angle of 90° and 45°. There are types of such a device and for professional work, with a rotating mechanism, in which the cutting tool can be rotated and fixed in any position.

How to cut a ceiling plinth properly

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

ceiling, plinth, wire, cutter

If necessary, you can make a crosscut with your own hands. For this you will need three scraps of plywood or boards of equal size. First, they are attached in the form of an inverted letter “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.

Inner corner

  • Make correct measurements.
  • We put a plinth plank in a notch so that this position exactly coincided with the placement on the ceiling.
  • The baseboard should be pressed firmly against the opposite wall of the jigsaw. Hold it and press it with your free hand.
  • Put the hacksaw at a 45° angle in the special hole and cut the piece.

When cutting soft materials (PVC, polystyrene foam) use a metal saw or a standard 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 line on the underside with a pencil, marking the desired length. It is necessary to consider that the edge (its top part) should protrude a little outside.
  • Move the skirting board into the joiner and cut it off.
  • The adjacent strip should also measure with a reserve and cut in a mirror to the first part.

Trying on the ceiling skirting: the joining of the parts must be perfectly flat. If the result is not achieved and there are irregularities at the joints, you can trim the edges with a regular knife to perfect the joint.

The second method. without additional tools

The easiest way to make a perfect join. by marking on the ceiling. can be used for the inner corner. Another example of how to cut a corner nice and straight.

The result will be an even angle of 45 °, if you draw a trimmer line from the point of intersection to the edge of the detail. Note that the above method of marking works only if the corners are perfectly even.

What to cut with?

Before you get to work, you should determine what material the ceiling plinths are made of.

Table. Materials used in the manufacture of ceiling plinths.

For your reference! There are special fittings to facilitate the difficult process of installing the fillets. These are special corners, designed for the insertion of skirting boards.

They are useful in that they hide the various errors made when working with the mounting of the fillets. You only need to cut the skirting at a 90 degree angle, and the corner will do the rest of the work for you. It can mask the holes and gaps, if any, make the ceiling look nice, and make the job a lot easier.

How to join in the corners

If the first corner has been installed, you can consider that you have almost learned how to do. “Almost” because you still need to learn how to join the corners and trim the strips to length. When glued some part of it already and a little distance left to the corner, how not to make a mistake with the length? The answer is simple: leave a margin.

The first time you can cut a piece 10-15 cm longer: you will be able to redo it several times, if something does not work at once. Then you make the corner as described above, trying on the dry, all adjusted to your satisfaction with the result. Only after that you can put the trimmed trim in the corner and mark the place to which it can be shortened. Cut should be exactly under 90 °. You do not need to use a jig. Just try to put the knife (hacksaw) perpendicular to the surface.

Provided that the work on the installation of the baguette in the corner of the room performs himself the owner, you can get a great result of decoration. All that is needed is attentiveness and following instructions. there is nothing complicated about the technological process:

  • With the help of a device is cut the end face at an angle, which allows you to make the junction of the fillet without a gap;
  • After fitting and adjusting, if necessary, the end of the baguette, it is glued to the wall;
  • all joints and gaps are sealed with sealant;
  • After the sealant has gained strength, it is sanded with sandpaper.

Finishing work

In the final stage of finishing the walls with a skirting board are sealed gaps between the skirting board and the wall. For painted walls use acrylic putty for this purpose. For the pasted ones. sealant. Leaks are removed immediately, before the mortar or sealant sets.
