How To Cut The Corners Of The Ceiling Plinth With A Miter Box

Self-made miter box

To make this device yourself, you can use one of the following methods:

  1. A U-shaped box is assembled from three strips or planks, on the walls of which grooves are marked and cut out under certain slopes.
  2. They take two boards and knock them down strictly perpendicularly. A piece of paper depicts a template with inclined lines for cutting at an angle of 45 degrees. The product is applied to the corner and pressed by hand, as when using a miter box, and a paper template is placed on the opposite side. Fillets are cut in accordance with the lines applied to the paper sheet. When cutting ceiling plinths, you can use anything that forms an angle of 90 degrees.

Tools used

Before you install the moldings, you need to have certain tools at your disposal. Some of them are always at hand from a home craftsman, while others will have to be purchased or made personally. When installing these decorative products, there will certainly be a problem with how to make a cut on the ceiling plinth, observing the required slope.

To solve this problem, they use tools that allow you to do the job correctly and as quickly as possible, including:

  • Pencil;
  • Roulette;
  • Hacksaw;
  • An ordinary, but better stationery knife;
  • Miter box.

How To Cut The Corners Of The Ceiling Plinth With A Miter Box

The last in the list above is a miter box. This is an easy-to-use and popular carpentry device that allows you to cut the corners of the ceiling plinth at a certain angle. Different materials are used to make this tool. Wood, metal or plastic.

There are always vertical slots on the side walls of the miter box, necessary in order to cut fillet corners at an inclination of 90, 60 or 45 degrees.

Cutting corners

At what angle the ceiling fillet should be cut directly depends on its location, or rather on whether the slope will be internal or external.

The cutting of the inner corner using a miter box is performed in a strictly defined sequence:

  1. The required length of the plinth is measured on the ceiling.
  2. The blank bar is placed in the fixture as it will be on the ceiling surface. To do the job correctly, the fillet must be placed face up.
  3. The workpiece is pressed against the far wall of the device and held with the left hand.
  4. Next, the file is placed at an angle of 45 degrees so that its handle is as close to the left hand as possible. To saw down the ceiling plinth. The cutting is performed without too much pressure on the hacksaw.
  5. Then you need to prepare a striker, for which the workpiece is moved to the far wall and held with the right hand.
  6. The hacksaw is turned at a 45-degree tilt. In this case, the handle is directed to the right and part of the plinth is cut off.
  7. After cutting the inner corner of the decorative fillet, the correctness of the work performed is controlled by joining the strips.

Acting in accordance with the above algorithm, it is possible, with an accuracy of one millimeter, to cut the corners of the ceiling plinth without much effort.

To make the correct cut of the outer corner, you must proceed as follows:

  1. First, as in the situation with the inner corner, markings are made on the ceiling by marking with a pencil.
  2. Further, the fillet blank is placed close to the near wall of the carpentry device.
  3. Holding the bar with your left hand, turn the hacksaw handle 45 degrees to the left and cut off.
  4. To saw off the mating element, it must be brought closer to the front wall of the miter box, holding it with your right hand. The fillet is cut with an inclination of 45 degrees, turning the handle to the right.
  5. At the end, the cut parts are joined, and if necessary, trim the surfaces, creating a neat outer corner.

Other cornering methods

When the contacting planes of the walls of the room form a right angle, the best solution would be to use a miter box. In other cases, you can use other methods, such as sawing the ceiling plinth at an angle, for example, by marking this product on the ceiling. This technology allows you to take into account all deviations regarding the angle, as well as the unevenness of the walls.

In this case, the work is performed as follows:

  1. First of all, two workpieces are cut according to a straight vertical mowing line.
  2. Next, one of the planks is applied to the surface, resting it with its butt against the perpendicular wall. Do the same with the second part of the skirting board.
  3. Their contours are outlined on the ceiling plane with a pencil. The point of intersection is the mark relative to which the fillet is cut, forming an angle in it.
  4. Then reapply each of the planks and mark the cut line on them, which will connect its two edges.
  5. The plinth is cut in accordance with the intended lines, after which both parts of it are connected and applied to the installation site.

If of all the ways how to cut the corners of the ceiling plinth, this one is chosen, it is important to take into account several nuances:

  • It is best used for interior corners;
  • You should not proceed to fastening the fillets one at a time, without making a preliminary docking of the two parts and without checking their relative position. The gaps remaining between the planks must be putty.

How to properly cut the corner of the ceiling plinth. Rules and methods

In order to hide the joints between the walls and the ceiling surface and to give the ceiling a finished look, fillets should be installed. In the process of performing this type of work, difficulties often arise, but they are mainly related to the fact that there is not enough knowledge of how to properly cut off the corner of the ceiling plinth.

Using a template

There is a way how you can cut the corners of the ceiling plinth without a miter box. Using a template. It is made of wood, cardboard or paper.

The markings are applied to the material in this order:

  • First draw two clear parallel straight mowing lines;
  • Between them determine the central point and outline it;
  • Using a protractor, apply the desired angles, which can exceed 90 degrees.

How to cut ceiling plinth and floor plinth and dock correctly

Installation of moldings on the ceiling and floor is the shortest and seemingly simple stage of repair. But surely many of you had to spend at least an hour trying to cut these 45 degrees. The only exceptions are the lucky ones with a technical mindset and those who were friends with geometry at school.

Today we will tell you how to cut the corner of a ceiling plinth and a floor plinth without resorting to complex calculations. You will see that this is not a difficult job at all, which can be done in a short time.

We cut the inner and outer corners of the floor skirting boards

Cutting floor moldings exactly is no more difficult than cutting ceiling moldings. Only the cutting tool is selected according to the material to be cut. The work itself will also be similar, only for manual cutting, a slightly different marking method is presented here.

How to properly cut a ceiling plinth at a 45 ° angle

Corner pieces for skirting boards can be easily trimmed on the miter box or by hand. In the first case, you will need a miter box and a hacksaw, and in the second, a pencil and a hacksaw / knife on cardboard. The hacksaw blade should be well sharpened so that you don’t have to think about how to cover up chips and roughness on the cut.

Cutting wood floor molding with a miter box

It is necessary to measure the distance from the edge of the skirting board already glued to the wall to the top of the corner of the wall. Now we take a new piece of molding and set aside a length equal to this distance on its lower edge. We put a point with a pencil or stick a piece of electrical tape. We do this procedure for both the outer and inner corners. In the miter box, place the plinth segments from left to right for the left side of the corner and from right to left for the right. In this case, they should be pressed as in the figure. To the side of the miter box closest to you.

How to cut a corner of a ceiling plinth. Laying a workpiece in a miter box:

  • For the outer left, match the mark on the skirting board with the extreme left slot. For the outer right. From the far right.
  • For the inner left, match the mark on the skirting board with the extreme right slot. For the inner right. From the far left.

Clarification: the notch refers to the one on the side closer to you.

Cut the corner with a miter box

Take a polyurethane skirting board designed for the left or right side of the corner. We lean it against the future installation site so that the end of the segment opposite from the corner is in the edge of the already glued molding. In the place where the lower edge of the ceiling plinth touches the top of the wall corner, put a point with a pencil or stick a piece of electrical tape. We repeat these actions with the second segment.

  • We place the left blank in the miter box from left to right, pressing it to the edge closest to us. The corner vertex mark must match the leftmost slot in the same edge
  • We place the right blank from right to left, pressing it to the near edge. Corner Vertex Mark. To Right Slot.

How to cut a ceiling plinth to an inner corner? Everything is very simple, the actions will be exactly the same, only the location of the corner vertex mark changes. Here, on the contrary: for the left segment. The extreme right slot, and for the right. The extreme left. The finished ceiling fillets must be combined, and then the joints must be looked at to the light. There should be no cracks. If they are very small, then editing is not needed, you can do with filling with putty after installation.

How to cut the corners of a skirting board without a miter box

If you are wondering how to properly saw down a ceiling plinth without a miter box, then the following information will be useful to you. We take the right segment of the ceiling plinth made of polystyrene, apply it to the installation site and draw a line on the ceiling along its upper edge. It should go beyond the points of the vertices of the corners by about 5 cm. Do the same with the left segment and put points at the intersection of the lines. We put the ceiling plinths in place one by one and transfer the resulting marks to them.

We figured out the upper part of the ceiling moldings, now we move on to the bottom. Everything is simple here, the marks we need are the tops of the corners. Mark their location with dots on the lower edges of the left and right ceiling plinths. Next, you need to connect the points on the moldings. This will be the trim line. This method will help to cope with even the most crooked corners. Adjustment is most likely not needed, and if it does, it will be minimal.

How to finish finishing the corners

We have figured out how to cut the corner of the ceiling plinth. Now let’s see how to finish the joints. How to cover the joint in the corner? In the event that a small gap remains here, the filling can be done with ordinary putty to match the color of the plinth. Joints can also be sealed with silicone sealant.

The gap between the planks in the inner corner can be filled with putty

What is miter box?

Cutting strips at an angle of 45g is done in a miter box

What to do if there is no miter box?

Thus, we figured out how to cut down the ceiling plinth (the above may help someone figure it out better) using a miter box. But what if this tool is not at hand? In fact, you can adjust the slats exactly without using it. There are two main ways to solve this problem: marking directly on the wall and making an imitation of a miter box.

In the first case, the procedure is as follows:

  1. The left strip is tightly pressed against the ceiling;
  2. With a pencil, a fishing line 1 is drawn directly on the ceiling along its upper edge;

How to properly cut a ceiling plinth without a miter box. Making the first line

  1. Next, the right ceiling element is attached to the ceiling and a fishing line 2 is drawn;
  2. A mark is placed at the intersection of the edge of the right plank with line 1;

The second line is drawn and a mark is put on the plinth

  1. Next, the left element is again attached to the ceiling;
  2. A mark is also put at the intersection of its upper edge with line 2;
  3. Now on each strip you need to connect the marks with the end of the lower edge of the plinth;

Then, according to the resulting mowing line, the actual cutting of the plinth at an angle is performed.

Without the use of a tray, mounting the planks in the corner can be quite neat

In order to cut an even corner, you can also use an imitation of a miter box:

  1. On a smooth plywood sheet, draw two strictly parallel mowing lines;
  2. We put a point on one of them and, using a protractor, connect it to the second line at an angle of exactly 45g (draw to the left);
  3. At a distance of 10 centimeters to the left of the first point, we put the second;
  4. We connect it with the second line at an angle of 45g (we draw to the right).

How to cut the corner of a ceiling plinth using an imitation miter box

The impromptu miter box is ready. Now it remains to attach the right ceiling element (wrong side) with the lower edge on the right to the mowing line closest to you and cut. The same with the left bar (only you need to apply it on the left).

Tip: You can cut the polystyrene strips with a knife. However, sharpen it properly. Otherwise, the material at the ends will simply crumble.

Corner pieces for ceiling plinths

Cutting ceiling strips when using corner elements (special connectors) is also usually done in a miter box. How to cut the planks in this case? It’s very simple. The cut is done at right angles. If there is no tray, you can use a regular protractor or square. Corner elements (photo):

When using corner elements, the strips are cut at right angles.

Trim ceiling plinth

Ceiling skirting boards are made from a wide variety of materials. Foam, polyurethane foam, plastic, wood. To trim them, the tools available in every home can be used. Styrofoam strips are cut with scissors or a knife. The wooden plinth is cut with a hacksaw for wood. How to cut a plastic skirting board is also not a question. You can saw it with an ordinary hacksaw for metal.

How to cut the corners of a ceiling plinth

The most difficult part when installing ceiling and floor skirting boards is the corner design. It is necessary to dock the planks in such places very carefully, otherwise the appearance of the decor will be hopelessly spoiled. Of course, you can use quite aesthetic special corner pieces.

However, naturally docked planks usually look more harmonious. And in this case you will not have to spend money on additional details. Therefore, later in the article, we will consider how to cut the corner of the ceiling plinth correctly and how to process the seam.

Using a miter box

The instructions for angular adjustment of skirting boards and fillets depend on what configuration the joint will have. As a rule, when performing repairs, the parts are connected perpendicularly, therefore in this section we will consider in more detail just such an option.

As noted above, the easiest way to cut corners is using a miter box.

We carry out the work according to the following scheme:

Cut directions when forming an inner corner

  1. We attach the part to the installation site, after which we measure the required length of the segment.
  2. Place the miter box on a flat, stable surface. A workbench is best suited for this purpose, since it will not be so convenient to saw on the floor.
  3. We put the bar in the miter box in the position in which it will be placed on the wall. We press the product against the wall of the tray in such a way that the flat parts adjoin the inner surfaces of the miter box.
  4. Hold the part with your left hand to prevent it from moving.
  5. We install the saw blade into the slot at the desired angle (the correct orientation for the inside and outside corners is shown in the diagrams and photographs). We carefully saw off the part, avoiding excessive pressure on the tool.

Outside corner cut

Advice!
Thin-walled skirting boards may crack when pressed.
To avoid this, we put a wooden glazing bead or any other block of a suitable size under it and saw them together.

  1. Now let’s start trimming the second corner. We put the other part of the plinth in the miter box symmetrically to the first one and also press it against the tray.
  2. We carry out trimming by installing a hacksaw in the appropriate slot.

After that, it is advisable to check how tightly the cut corner pieces fit together, and only then proceed to gluing them.

You need to connect the fragments only after preliminary adjustment

We cut the corners of the ceiling plinth without a miter box

How to cut a ceiling plinth without a miter box correctly? For work, you need a well-sharpened pencil, a small piece of plinth, a stationery knife (for polystyrene or polyurethane) or a metal saw (for other materials), a ruler.

You need to attach the plinth to the corner and draw the line with a pencil along the outer edge, then attach to the other side of the corner and also mark. As a result, a cross will appear on the ceiling, the center of which will mark the place where the plinths of the ceiling plinth should converge. Place a piece of skirting board where you will glue it. Resting the end against the wall, transfer the desired mark to it. This way you can cut the corners of the skirting board without a miter box.

Pruning technology. Ceiling plinth corner

Without using a miter box

The price of such a device as a miter box for a baguette and plinth is relatively low, but at the right time it may simply not be at hand. Of course, in this situation, the complexity of the task will increase, but you can still cope this way.

Layout scheme

The first method is suitable for ceiling fillets and involves the use of markings on the ceiling:

  1. Cut both parts to be joined to 90.
  2. We apply one panel to the attachment point, press it tightly, align and push the butt against the perpendicular wall.
  3. Use a pencil to draw a line outlining the outline of the panel.
  4. We remove the panel, lay the symmetrical part and repeat the operations.
  5. Now we have the intersection point of the two lines on the ceiling. We apply the details to the base one by one and make marks opposite this point.
  6. Having laid the plinth on the workbench, we connect the mark to the corner and trim along this mowing line.
  7. As in the previous case, we check the quality of the skirting board joint.

Sequence of actions during work

For skirting boards you can use templates:

  1. We take two strips of thick paper or cardboard, the width of which corresponds to the width of the baseboard.
  2. We attach them to the installation site of the product, noting how the connecting line should go.
  3. We cut out templates according to the marks, which we then lay on the plinth and use as a template for cutting.

Advice!
You can only use one pair of templates in order to join several corners if you are sure that they are perfectly perpendicular.
Otherwise, the gaps will be large enough, and laborious adjustment will be required.

Using markings on cardboard

We only dream about peace, or how to make the corner of the ceiling plinth if the walls are blown apart

Before cutting the corners of the ceiling plinth, measure the mAL-KO

When the bevel is made, measure the angle by pushing the slats apart, both parts should rest against the walls, fix the position by tightening the tie bolt more tightly. Then attach the bevel to a thick piece of cardboard, outline the outer contours of the corner, and cut out the paper template. Fold the resulting shape in half, connecting the edges evenly, so you find the middle of the corner. Further, for convenience, transfer the template to MDF, plywood, HDF, do not forget to mark the middle, carefully cut out a new template along the contour, along which the inner corners will be cut. To grind the outer corners, you need to cut out your template, for this, the mAL-KOy corner is “wrapped around”, the internal parameters are transferred to the template.

First, the plinth is applied on one side of the template, the marks are transferred to the strip, connected by a line along which the cut is made, then the second plinth is measured and cut in the same way, the ends are abraded and glued in place.
