How To Cut A Plastic Ceiling Plinth

How to cut a plastic ceiling plinth Ceilings Ceiling plinth performs not only a decorative function, visually separating walls from the ceiling, but can also hide the joints of various finishing materials of the ceiling and walls.

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 designs of a miter box for cutting at angles of 90, 60 and 45 degrees. For more professional work, a miter box with a rotary mechanism is used, where the hacksaw can be fixed at any angle to the workpiece.

How to cut a ceiling plinth with a miter box:

  • We apply the plinth to the ceiling, measure the required length.
  • Then we install the plinth plinth in the miter box so that the position coincides with the position of the plinth on the ceiling.
  • The plinth strip should be pressed against the far wall of the miter box.
  • We hold the plinth with your left hand.
  • We choose such a position of the hacksaw when the angle is 45 degrees and at the same time the handle of the hacksaw is as close as possible to the left hand.
  • We cut the workpiece 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.
  • Press and hold with your right hand.
  • We choose 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, you must start cutting from the front of the skirting board. Wooden skirting boards will most likely need to be filed after trimming.

How to cut a ceiling plinth 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 planks may not be enough in length.
  • It is necessary to attach the plank to the ceiling and outline the 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.
  • We 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 only suitable if the angle between the walls is even 90 degrees. If the accuracy is poor, you will have to use other methods.

The ceiling plinth performs not only a decorative function, visually separating 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 difficult in attaching this fillet element, 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), polyurethane and wood.

PVC ceiling skirting boards are the cheapest. They are easily dents and creases that cannot be repaired, so the product must be thrown away. Also their disadvantage is electrostaticity, the ability to attract dust. You can cut them with a sharp construction knife or a 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, without 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. They are 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, 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 begin to crackle slightly. If you try to process or cut such a plinth, it may bend or deform in other ways.

Wooden ceiling skirting boards are dense, heavy pieces 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 of how to properly cut the ceiling plinth, I would like to note that there is a possibility not to cut the plinth with great precision. Available for sale special corner pieces, 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 skirting boards themselves, therefore 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 come in handy for those who nevertheless decided to accurately cut the skirting boards at a given angle.

How to trim a ceiling plinth using a miter box template

Something resembling a miter box can be done by applying the required cut angles to paper, cardboard or wood. Draw two parallel mowing lines, locate the center, and then set the required angles using a protractor. 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 with a corner and measure it with a protractor.

The technique for cutting a ceiling plinth using a painted miter box is exactly the same as using the miter box itself. We press the plinth plank to one of the parallel lines, then set the hacksaw at the desired angle, which is already outlined, and cut it off.

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 strip suspended during the cutting process. Otherwise, you can mark the angle for cutting in this way even more accurately 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 skirting board:

  • The first step is to cut two workpieces at a 90 degree angle.
  • Then we first apply one plank, resting 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 pushing its end against the wall. We outline the line.
  • The intersection point 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 other 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.

DIY impromptu miter box

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

Method 1. 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. As a result, you should get a wooden miter box in which grooves are cut.

Method 2. 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 strip, since it is difficult to keep it suspended. It is 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 baseboard blank to the corner, press it with our hand, as described in the technology for using the miter box, move the piece of paper with the template under the edge where we are going to cut it, and cut it off. In the process of cutting, we focus on the line drawn on the paper.

Method 3. As an impromptu miter box, you can use anything, anything. That we form an angle. For example, a table pushed against a wall.

It is not necessary to fix the plinths of the ceiling plinths before you cut the striker and try 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 the 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-practice on small blanks.

How to make a corner of a ceiling plinth without a miter box

Few people in apartments or houses have angles exactly at 90. Small deviations are easily corrected after fitting. But not always. Then you have to mark everything in place under the ceiling.

You will need a thinly contoured pencil (hard it is not so visible on the ceiling, but leaves quite clear marks near), a small piece of baseboard, a ruler and a good stationery knife if you work with polyurethane (polystyrene) baguettes or a metal saw to work with the rest materials.

Apply the plinth to the corner, draw along the outer edge with a pencil. Apply to the other side of the corner, also mark. You have a cross on the ceiling, the center of which marks the place where the plinths of the ceiling plinth should converge (look at). Having installed a piece of plinth in the corner, which will be glued there and resting it with its end on the wall, transfer the mark to it.

How to make corners on skirting boards without using special tools

Now take a ruler and connect the edge of the skirting board to the marked mark. If you just put the plinth on the table and cut off along the mowing line, the two parts in the corner will still not fold: the inner part will interfere. It can be trimmed later by trying on the ceiling. The second way is to place the piece to be cut on the table with the piece that will be on the ceiling. And cut along the mowing line, but holding the knife at an angle of about 45. You will still need to adjust, but much less (and less chance of error).

Repeat the same operation with the second bar. Put it against the desired wall, rest the butt against the adjacent wall, mark the place where the cross is drawn, draw the line and then cut it off. Correction Carried out dry without applying glue.

You repeat exactly the same steps for the outer (protruding) corner. Now you know another way to make a corner of a ceiling plinth, and without a scissor or other special devices.

How to cut ceiling plinth in corners

The quality of the ceiling finish greatly affects the appearance of the room. Therefore, they try to do everything perfectly, or very close to it. The finishing touch to the design is the ceiling plinth. They give the finish a complete and holistic look. The strips themselves are mounted on flat surfaces simply: on special white glue, but problems arise with the design of the corners. Without knowing how to make the corner of the skirting board correctly, a lot of material is spoiled. We will tell you about how and what to cut it in the corners.

How to get the correct angle

Most of the problems when working with skirting boards arise in the design of corners. Since the surface of the products is complex, it will not be possible to simply cut off at the desired angle: it is also necessary to cut so that they dock and preferably without large gaps. There are actually several ways to make the corner of your skirting board perfect (or almost).

What and how to cut

Working with skirting boards made from different materials means using different cutting tools. When working with a wooden skirting board, it is more convenient to work with a saw on wood. All others, including plastic ones, made of polystyrene and other polymers, are better cut with a blade for metal. The result is a smoother cut, less burr. Saws are usually used when working with a miter box.

Corner design looks attractive

When working with polystyrene skirting boards, they cut them with a good stationery knife without special devices. Its blade is quite thin and even, the cut is smooth, not wrinkled. If you work with a saw with polyurethane or polystyrene, do not press hard: you can wrinkle.

In general, in order to get used to the tool and material a little, take a piece and practice on it: cut, saw, trim. So there will be fewer problems when working.

With decorative corners

There is one more, simpler way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory decorative corners. They are installed in a corner, strips are glued to them closely. It is very easy to cut them if necessary: ​​by a few millimeters with an ordinary clerical knife.

How To Cut A Plastic Ceiling Plinth

Using a miter box

If the corners and walls in the room are even, you can use a special miter box carpentry tool. This is a groove in the form of an inverted letter P, in which the mowing line is outlined for cutting at an angle of 90 and 45. The part in which you want to cut is laid inside, the saw is inserted into the guides. The part is held in place, cut at the desired angle.

This is what the miter box looks like. Can be plastic, wood or metal

In the case of skirting boards, not everything is so simple: they must simultaneously adhere to two surfaces, therefore they need to be pressed against one or the other wall of the miter box. When working with ceilings, they are pressed against the side closest to you.

The sequence of actions when finishing the outer corner, you need to make a gash at an angle of 45 degrees. Place the miter box in front of you. Trying on how the plinth will be located, determining which part of it will be attached to the ceiling. In order not to get confused and cut off the ceiling plinth correctly, put the strip that will be located on the right on the right, the one on the left on the left.

How to cut a corner on a ceiling plinth: install it correctly in a miter box

Press the part that is on the ceiling to the bottom of the miter box. The other side is closer to you and raised. Lean it on the wall of the device so that it does not stagger when cutting. That is, the front of the skirting board turns out to be turned away from you. Make the cutting direction as shown below. By folding the two cut pieces together, you get a projecting outer or outer corner.

First put the cut off parts in place on a dry one, without applying glue. If the geometry of the corner is not so perfect, you can tweak it a little with a knife. It is easier to cover small errors with a special putty.

The situation is very similar with the inner corner of the skirting board. First, you try on which side will be on the ceiling, press this part to the bottom of the miter box, lean the second part on the wall closest to you and make cuts as shown below.

And again, first try on without applying glue, if necessary, slightly adjust. Then apply a thin bead of glue to both surfaces that will adhere to the wall or ceiling.

Your own version of how to use the miter box correctly is shown in.

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 relatively inexpensive, and therefore foam models are becoming 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 utility 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 therefore a sharp and thin knife is used for this purpose.

  • Wood. Such skirting boards are more difficult to process, although they have many advantages (environmental friendliness, durability). They cost more
    especially if made of hardwood. Before cutting a wood skirting board, 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 notches on the sides. A hacksaw or knife can be inserted into it at the desired angle. Thus, the cutting angle is as accurate as possible.
    1. 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.
    2. 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 degrees.

    3. Before cutting the corners, mark the vertical direction with a simple pencil.

    Skirting board cutting technology

    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 particular difficulties in the process. If it is not there, then two options are possible: cut according to a template and measurements on the ceiling, or make this tool yourself.

    Rules for cutting ceiling plinths by marking

    This method is used to cut the skirting board in cases where there is no miter box or parts from which it can be made.

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

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

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

    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 line segments that intersect at one point.

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

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

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

    • Cut off the baguette along the mowing line.

    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.

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

    Method for cutting a ceiling plinth without a 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 apply the end part of the baguette to the sheet of paper and outline the outline of the convex side. It is more convenient to use a small section of the baseboard (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, we apply one plinth 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 subsequently sealed with a sealant.

    Features of cutting ceiling plinths in a miter box

    It is necessary to work with this device with extreme care so as not to blunt the tool and not leave 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 be pressed against the ceiling on the miter box should rest against the sidewall.

    We insert a cutting tool (hacksaw or knife) into the required 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 corrected 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.
