How to trim the corners of the baseboard on the ceiling

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

Any repair requires attention to the smallest details. 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 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 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 what material it is made of. Cutting is different, because the baguettes have different density. The first thing to consider are the most popular materials and how to cut them at the same time.

Styrofoam

Such products have the lowest price, because the material is very unstable to mechanical influences. Foam is easy to scratch, damage at an accidental blow. Pros. 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 very sharp tools. Otherwise, the skirting board could crumble, so it would be unsuitable for installation. This is true for both angular and flat cuts.

Styrofoam

This contender is more expensive, but it is not very different from the first candidate, because it is a “relative” of Styrofoam: it is made from expanded polystyrene. This material also consists of small granular bubbles, but they stick together more densely. But Styrofoam 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 instrument.

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

Extruded polystyrene foam

EPPS 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 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 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 tool for its cutting is not required, but bluntness of the cutting edge is also not welcome.

Polyvinyl chloride

Plastic baseboards (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 to dock them use special, ready-made corners.

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 has a 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. Polyurethane skirting boards do not crumble, do not deform, with honor endure almost any pressure.

Wood

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

The ideal tool for cutting wooden materials 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 a decent job.

Tools in use

First about how to cut a polymer or wood ceiling plinth, how to do it correctly and quickly. In this case, you will need two tools for work. a wire cutter and a cutting tool.

How to cut baseboards?

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

• Foam products (all polystyrene) involve the use of a sharp office knife;
• Polyurethane skirting boards are usually cut with a metal hacksaw;
• Wood requires “active” participation of the jigsaw or saw.

The second potential tool for polyurethane is the same penknife. The reason: quite a low density of the material. Another alternative is a sharp, pointed kitchen knife. The special requirement for it is not too thick a blade.

Possible substitute for a wood jigsaw. a metal saw. The blade that has the smallest teeth 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 chisel and its own making

The chisel is the second indispensable tool for working with baseboards.

What it is?

Not everyone may know what it is. This is a device that makes it possible to cut any workpiece at different angles (45-90°). This is a trough, consisting of the bottom and two sides in which slots are made for tools. On 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 the parts will not work: or there will be a gap between the adjacent skirting boards, or they will simply need to be trimmed again, as it will be impossible to dock the adjacent products.

Yes, the remaining hole can be masked with some 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?

To make it yourself will need to find a board length of about a meter or more, or a sheet of plywood (chipboard). You still need to prepare:

• From the selected material is cut 3 parts with a width of 200 to 250 mm, their length. 300 mm (400, 500 mm). Use self-tapping screws to connect them in a “U” shape.
• Using a protractor, the upper parts of the sides make marks corresponding to the angle of 45 ° (if necessary, and 90 °).
• Then take a hacksaw, which cuts holes so that the grooves reach the bottom of the tool.

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

How to trim the corners of the ceiling plinth: general rules

Trimming should be carried out on the outer edge of the skirting, as well as on the inside (when forming the outer corner) or the front side (for the internal joint).

If everything is done correctly, the texture of the eaves will not be damaged. In the home most often used finishing materials of foam. The technology of joining the elements is as follows.

• Using a protractor, measure the angle between the walls. In the case where it is strictly equal to 90°, the edges should be cut at 45°. The action is performed with both elements.
• If the joints between the ceiling and the walls are not straight, the radius of the corner should be divided in half. In this case, the baguette, which will be attached to the left side, is cut to the right, and the right element, respectively, to the left.
• The edges of the inner corner details are trimmed so that the upper part is shorter than the lower part. The edges of the outer corner are formed differently: their lower part is shorter than the upper.
• Unlike skirting boards made of foam plastic, wooden parts need to be precisely adjusted to each other and to adjacent surfaces by applying and trimming along the contiguous line.

How to cut a skirting board without a plough

Suppose you have an urgent need to glue a ceiling plinth.

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

• Both parts of the skirting board are first cut at right angles.
• The position of the elements is marked on the wall, and a trimmer line is applied to join them together. As a result we see two intersecting lines. Their intersection point is projected directly on the baseboard details.
• The skirting board is put on the ceiling and a trimmer line is drawn from one edge to the other.
• Finishing of details is carried out by a clerical or construction knife.
• A virtual jigsaw is drawn on paper with lines at the right angles. The baseboard tacks are placed against the notch and the cut is made (with the blade of the knife held vertically).

How to cut the corner of a ceiling plinth with Комментарии и мнения владельцев from a specialist will help to solve this problem.

Advice! Since the inner or outer corner is not always in perfect shape, the ceiling plinth will have noticeable cracks in the joints.

To make them less noticeable, before gluing the skirting boards on their ends should be applied plaster putty. After joining the elements, remove excess putty 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 a pattern. What to do in such a case? The answer will prompt a video.

How to properly cut the corners of the ceiling plinth

Ceiling plinth can be made of wood, plastic, foam plastic. The latter variant is the most common. It has an affordable price, many varieties and is easy to work with. To trim it, usually use a sharp knife.

Before you begin, you need to cut the material according to the perimeter of the room. You can draw a diagram on paper in advance, noting all of the corner connections.

The technology of cutting the corners of the skirting

Trimming the baseboards in the jigsaw. Trimming technology

• The right strip is placed in the jig from left to right. The back part, which will be attached to the ceiling, lies on the bottom.
• Profile is pressed firmly to the tray and cut at an angle of 45º.
• From right to left another plank is put and cut the same way.
• The corners of the cuts are joined at the attachment point and corrected with a knife (for foam plastic and plastic).

The standard room has a rectangular shape with 90º corners. In fact, such perfect angles are quite rare and are only the dream of the installer. If you are lucky, then the procedure for cutting the corner of the edge of the baseboard is as described above, it is very easy to do it with an end piece.

When trimming, you need to remember which side the baseboard will be located. To create a perfect corner for wooden surfaces or joints, you can use putty, but a good carpenter will never do this, but simply saw evenly.

Tips

Despite the fact that it is not so difficult to glue ceiling skirting boards, there are tips that you should heed:

• The walls must be clean and dust free. Any dirt will reduce the adhesive properties of the base.
• The underside of the skirting boards is better to make a rough surface, as the smooth surface has a low quality of adhesion to the surface.
• It is important to choose a quality adhesive with a good fixation, especially for heavy baguettes. Also, you should not use glue with solvent for skirting boards made of polystyrene, such a composition can ruin the material.
• After gluing the ceiling plinths, do not allow draughts in the room within a day, the glue must be well cured.

Selection of tools for cutting ceiling plinths

To cut a ceiling plinth correctly and accurately, it is necessary to use a suitable cutting tool. It is chosen depending on the material from which the skirting is made:

Styrofoam. It has a low strength and is 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 planks 5015 cm nailed a long rib in the shape of a tripartite, rectangular box. Pay attention, between the side planks and the cross plank should be maintained at an angle of 90 degrees.

To work with this homemade device was convenient and safe, the boards should be well sanded before stapling.

Technology of cutting ceiling plinths

To get the job done quickly and efficiently, you need to match the tool to the baseboard material and choose a cutting method. If you have a joiner, there will be no special difficulties in the process. If you do not have one, then you have two options: to cut according to the template and measurements on the ceiling, or to make this tool yourself.

Features of cutting ceiling plinths in the jigsaw

Work with this device must be extremely careful not to blunt the tool and not to leave jigsaws in unnecessary places. In the process, follow the following instructions:

Fix the baguette in the jig the way you plan to place it on the wall. The side that will be pressed to the ceiling on the jig, must fit to the sidewall.

When cutting and trimming products from foam and polyurethane remember that these materials crumble and squeeze, so tools should be sharp enough, and a strong mechanical impact on them is undesirable.

Technique of cutting ceiling plinths on a template

This method can be used if your corners are straight, and you need to trim the baguette exactly 45 degrees. To do this, before you cut the ceiling plinth in the corners, you need to draw a jig on heavy paper. Draw two parallel lines and mark the corners at the desired degrees, using a protractor.

Place the fillet in this case in the same way as on a traditional mortiser. Take into account, that you should cut a skirting board, keeping a tool in a strictly vertical position.

Rules of cutting ceiling plinths according to the marking

This method is used to cut the baseboard in cases where there is no jigsaw or parts from which it can be made.

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

Apply the baguette in the corner to the place of fastening.

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

How to cut a ceiling plinth without a joiner

To join the skirting boards accurately at interior corners, you can do without a joiner.

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 available).

Not every interior design involves the use of a ceiling plinth, but most often the overall appearance of the room seems incomplete without it. In the attachment of this element. moldings. there is nothing difficult, almost all types of baseboards are mounted on the glue. But the question of how to properly cut the ceiling plinth in the corners of the premises, can puzzle many.

After all, even in the simplest rooms, there are internal corners where ceiling plinth strips must be accurately and beautifully docked. And in a more complex configuration of the room will have to join the skirting boards, making the outer corner. In this article we will consider different options on how to cut the ceiling plinth with or without the help of hand tools.

To begin with, we should deal with the question of what to cut the ceiling plinth, the answer depends on the material from which the fillet is made. PVC, polystyrene (polystyrene foam), polyurethane and wood ceiling skirting boards are currently on sale.

PVC ceiling skirting boards are the cheapest.

They easily form dents and creases, which can not be removed, so the product has to be thrown away. Also their disadvantage is electrostatic. the ability to attract dust. They can be cut with a sharp construction knife or hacksaw.

Skirting boards made of expanded polystyrene are also among the cheapest. This material is very fragile, when processed easily crumbles, so cut the polystyrene must be a sharp knife or hacksaw for metal, not making too much pressure.

Ceiling plinths made of extruded polystyrene foam are slightly more expensive than polystyrene foam, they are denser and more difficult to cut. Nevertheless, they crumble less, so they are easier and more convenient to work with. They can be cut with a construction knife and a metal hacksaw.

Polyurethane skirting boards are the most expensive at the moment. They are strong, flexible 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 differences. For example, over a gas stove, a polyurethane skirting board will get residual deformations and begin to crack slightly. If you try to trim or trim such a baseboard, it may warp or deform in other ways.

Wooden ceiling plinths are dense, heavy products that can only be cut with a hacksaw, preferably with fine, frequent teeth. You can also use a metal blade.

Before proceeding to the listing of ways, how to properly cut the ceiling plinth, I would like to note that there is a possibility not to cut the plinth with special precision.

There are special corner pieces available on the market, into which the edges of the skirting board are inserted. In this case, the plank plinth trim enough to trim at an angle of 90 °, and the corner element will hide all the flaws. But this method is not always used, because the size of the corner elements are somewhat larger than the baseboards themselves, so the corners in the room will stand out against the background.

This can sometimes look clumsy. Nevertheless, if the room design allows the use of corner elements for ceiling skirting, it makes sense to use them. The following instructions will be useful to those who still decided to precisely cut the baseboards to a given angle.

How to cut a ceiling plinth corner with a whiteboard

The chisel is a simple carpentry tool that allows you to cut the workpiece at the required angle.

The most common is a tray of plastic, wood or metal with vertical slots for cutting at 90° and 45° angles. There are also more complex designs of the plinth cutter. for cutting at angles of 90, 60 and 45 degrees. For more professional work use a saw with a pivoting mechanism, where the hacksaw can be fixed at any angle to the workpiece.

How to cut a ceiling skirting board with a power wire. inside corner:

• Hold the skirting board against the ceiling and measure the required length.
• Then put the baseboard plinth in the jig so that the position coincides with the position of the plinth on the ceiling.
• The baseboard plank should be pressed against the far wall of the woodworking jigsaw.
• Hold the skirting board with the left hand.
• We choose the position of the hacksaw when the angle is 45 degrees and the handle of the hacksaw is close to the left hand as much as possible.
• Cut the skirting without pressing the saw too hard.
• The next step is cutting the skirting board. Install it also to the far wall of the jig saw.
• Press it down and hold it with your right hand.
• Choose a position for the hacksaw where the angle is 45 degrees and the handle of the hacksaw is close to your right hand.
• Cut the skirting board.

Next, we dock the cut skirting boards and check the accuracy of the cut. For a more accurate orientation, they also say that to do the inner corner, you need to start cutting from the front of the baseboard. Wooden skirting boards after trimming, most likely, will need more fit file.

How to cut the ceiling plinth with the plinth joiner. the outer corner:

• To not make a mistake with the size, it is better to start with the marking of the inner corner, and then already cut the outer corner. Otherwise it is possible that the skirting board may not be long enough.
• It is necessary to attach the skirting board to the ceiling and measure it.
• Install the ceiling plinth plank and press it to the nearest wall.
• Hold with the left hand and choose a 45 degree angle position for the hacksaw when the handle is close to the left hand.
• Cut the workpiece.
• Position the skirting board against the nearest wall, hold it in place with the right hand.
• Set the hacksaw at a 45 degree angle with the handle close to the right hand.
• We cut the workpiece and dock the corner.

Trimming workpiece with a wire trimmer is suitable only if the angle between the walls is even. 90 degrees. If, however, the accuracy leaves much to be desired, you will have to use other methods.

The second way. without additional tools

For an inner corner, you can use the easiest way to perfect the junction. by marking on the ceiling. Another example of how to cut a corner nice and smooth.

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

Other ways

With good eye and accuracy of action of the hands you can use a homemade template, which resembles an imitation of a jigsaw. To do this, take a thin board or thick plywood and draw a layout in the form of a horizontal rectangle. Using a protractor, mark 45° on the right and left sides of the rectangle. Draw lines connecting the opposite edges. Now you can cut the ceiling plinth with this layout. The steps are simple and similar to the description above in the first option. Only the ceiling parts should not be inserted, but superimposed on the drawing and combine the hacksaw with the marking of the layout.

Special accessories for the junction

Installing ceiling plinths, you can bypass the question of how to cut the corner of the side. In a situation where you do not want to cut anything, if you are a woman and like beauty, but not carpentry work, you can go the other way. We advise you to choose a skirting board for your finishing, to which you will find a matching part in the store, closing the joint. This method will save time and effort.
