Plastic corners to protect the corners of walls: types and installation
A variety of materials are used for interior finishes. They all differ in appearance, their properties and performance. No matter what material you’re working with, beautiful framing in the corners is still a real problem. Even materials like ceramic tile need to be protected, much less putty, to protect them. A careless blow can easily damage these places, after which the appearance of the whole repair loses its luster. Today we will talk to you about plastic corners to protect the corners of the walls, learn all about installation and their varieties.
It is worth explaining right away that the corners are external and internal. The first, as is not difficult to understand, are mounted on top of trim, and the second under it. This means that the functionality of the elements is slightly different. Both types serve to protect outer corners from the impact, and the outer have an additional aesthetic message. There are also corners and internal, which protect not from the impact, but from deformation changes in the base of the walls, keeping the outer trim intact. Let’s take a closer look at each type of angle.
Table 1. Varieties of plastic corners.
There are some other models of corners, but they are very specific, so you don’t need them when finishing walls.
Installation of plastic corners
So, in fact, we have three types of corners, which are mounted on different materials and for different purposes. Let’s take a detailed look at how to install each.
Hidden corners under the putty
To work we will need such a set of materials and tools:
- The perforated corner itself.
- Putty or gypsum plaster, depending on which step you are doing the installation.
- A container to mix the mixture.
- A pair of trowels.
- Something to cut the corner, such as metal scissors.
- You can also use a stapler to fix the piece in place first.
Step 1. applying putty to the corner. Cut the corner to length and mix the putty in the bucket. Next, we dial it up with a trowel and apply it directly to the corner so that it hits both adjacent walls. We pass in this manner the entire area on which the corner will be glued.
Step 2. installing the corner. We put the corner in place and press it into the putty. Press down firmly to leave a minimal layer under the plastic.
Interesting to know! Plastic corners often have a bulge in the middle, so you need to build up a layer of putty to fit the corner smoothly. To avoid this, you can grind the walls, which will allow you to recess the part inside. You can not do it on drywall, so we go as we go.
Step 3. press the corner. It is necessary to press the corner from both sides at once. Use a trowel for this. this will allow the most accurate alignment in plane with the walls.
Step 4. Smoothing the putty. Then we spend with a putty knife on a corner and remove all putty, simultaneously smoothing it out and filling up the gaps. Make the edges as even as possible, but do not try to create a perfectly smooth surface. this is not the point now. At this step you can check the evenness of the position of the angle with the level, and make adjustments if necessary.
Step 5. pulling the corner. Let the starting layer of filler dry, and then proceed to level the corner. We will need a small rule that helps to smooth out the difference, because of the protruding angle. We apply putty on the walls and stretch it, obtaining an even and beautiful corner. In principle, that’s all, but if you want, you can once again coat everything under zero with a trowel after this layer has hardened.
Thanks to the rigidity of the corner, we managed to achieve the correct geometry of the outer corner of the window slope, to do it only with a trowel is also possible, but requires some experience, and durable such a corner will not be.
If you’re not a fan of whitewashed plaster walls, but you want to be able to change the look and feel of rooms more often and without much cost, then why not look at the side of wallpaper, which can be painted repeatedly? In a special article, we will tell you how to paint wallpaper for painting correctly, strictly according to technology, so that they served for a long time.
for different types of fillers
- Painted adhesive tape for the preliminary fixation of parts.
- Liquid nail adhesive and a nail gun.
- A office knife with thick blades or metal scissors to cut the corner.
- Measuring tape and a pencil.
- Silicone sealant for masking possible cracks.
- Angle gauge to reconcile the angle of 45 degrees.
In the example we will look at how the window sill is framed.
Step 1. prepare the workplace. To avoid damaging the window sill (to dirt and scratches), it is first necessary to cover it with something. We have this laminate substrate. We put all necessary tools on top so that it was always at hand.
Step 2. measuring the sides of the slope. We measure the height of any of the sides of the slope with a tape measure. It is important to focus on the distance from the window sill to the edge of the horizontal side of the slope. No tolerance for error, so measure everything to the millimeter. use a good tool, not a rusty old one that can’t make out the graduations.
Step 3. Marking the corner. We transfer the received sizes on a corner and we put a mark with a pencil. Make sure that the angle does not bend, otherwise you will get a big error. It is best to lay it on a flat surface and make all measurements in that position.
Step 4. marking at 45 degrees. We take the square and install it as shown in the photo, oriented exactly at the mark made earlier. Draw a slant line for the trimmer, which is where we’ll cut the piece.
Tip! The first mark is also better to make at the corner, setting exactly 90 degrees, so as not to make a mistake when cutting.
How to Cut a Plastic Corner at 45 degrees
When repairing works in the premises baseboards play a decorative role, they are the finishing touches of design. They are also designed to cover joint imperfections between different surfaces. Proper gluing of ceiling and floor skirting boards. a simple task, but responsible. In this regard, the question of their installation becomes particularly crucial.
The photo shows the joining of skirting boards in an inner corner of the room.
The floor plinth is represented by a very wide range of products:
- Of PVC foam, plastic, produced with cable channels for wiring and in their absence.
- Of wood, made of different types of wood, solid or otherwise laminated; the installation of wooden baseboards is no different from the installation of plastic trim.
- Iron, iron and dural, with cable channels and flat.
Plastic or iron products are supplied with various fasteners and terminations which are simple to install. Because it is actually never a question of how to cut plastic baseboards in the joints. Wooden products are devoid of such fasteners. They need to be notched for a perfect fit.
The principle is. Of wood skirting boards before installation should be kept on the room to which they are provided for more than a day. Like any wooden product, it must adapt to temperature and humidity.
Let’s look at how the trimming process is done.
To connect the slats when bypassing the corners is the question of how to cut the skirting at 45 degrees? It is painfully simple, but it is better to have a special device called a chisel.

Not a principle, professional tools made of metal or more ordinary versions of plastic or wood fixtures you buy, they will help to perform this work in artisanal conditions without excessive worry.
In this case, the cost of professional device is justified, if you have to frequently engage in such work. For small volumes, you can be limited to a more ordinary and cheap variations.
Principle. The height of the walls of the machine should overlap the height of the trim strips to get a smooth cut.
Fixture for sawing molded products, arrows show the technological slots to perform the work in accordance with the annotation.
- Prepare two pieces of the river for the joint;
- take the first piece, insert it into the jig from right to left so that it lies on the reason, as on the floor and leaned against the far wall of the fixture, as against the wall;
- sawing the product from the left end, passing the saw through the hole number 1;
- The second section is inserted into the device from left to right, exactly adhering to the orientation of the floor and wall;
- Saw it from the right end, passing the saw through the hole number 3.5.
- Prepare two pieces of skirting board for the joint;
- take the 1st piece, insert it into the tool from the right to the left so that it rests on the base. as on the floor and leaning against the far wall of the tool, as against the wall;
- Saw it through from the left end, passing the saw through the hole at no. 5;
- The 2nd piece is inserted into the tool from the left to the right, precisely observing the orientation on the floor and wall;
- Saw it from the right end, moving the saw through the hole number 1.
Advice. At the junction along the walls is better to cut the laths at 45 degrees, after such a connection is completed, the joint will be practically unnoticeable. Trim laths are inserted into the tool from 2 sides, as if leaning against the wall, trimming occurs through a single technological gap. First they undercut one, then push the 2nd toward it, pushing the 1st away from the gap, and then cut the 2nd.
How to glue plastic corners on slopes
We figured out how to cut a floor plinth. as we see it is not that difficult process.
Ceiling tiles for cutting are applied to the side of the tool closest to the working man.
Let’s consider at this point how to cut the ceiling skirting boards, what is the principle difference between this process and the trimming of floor products.
The main rule that must be understood is that the ceiling tacks are attached to the side of the cutter that is closest to the person working with the child. At the same time, the side of the baseboard, which should lie on the ceiling, will we lie on the base of the tool.
Perfectly executed produced trimmed ceiling tacks.
Annotation on cutting the inner corners of the ceiling plinth:
- Prepare two pieces of fillets for docking;
- take the 1st piece, turn it over and put it into the jig from right to left so that it rests on the base of the jig, like on the ceiling and leaning against the wall of the unit closest to our site, like on the wall;
- we make the bar from the left end, passing the saw through the slots at number 2.4;
- Put the 2nd piece to the left side of the jig from the right, keeping the orientation;
- sawing it from the right end, through the slots at number 1.
- Prepare two pieces of the fillets for the junction;
- we take the 1st piece, we put it in the tool from the right to the left so that it lies on the base of the machine as on the ceiling and leans against the wall of the tool closest to our site as against the wall;
- saw it from the left end, through the slots at number 1;
- The second piece is inserted into the jig from left to right, precisely following the orientation;
- cut it at the right end through the hole number 3; 5.5.
How to attach the plastic corners?
First note that before the direct installation of plastic corners on the windows it is necessary to cover the room with wallpaper, paint, etc. That is, you can begin to mount them only after all the work on finishing.
To install a plastic corner, you will need the following tools:
- mounting glue (liquid nails)
- masking tape (tape), and in a room with high humidity. silicone sealant
- Metal scissors or a hacksaw
- PVC nooks
Window finishing with plastic nooks and crannies consists of several steps. Consider each of them:
Depending on the place of use, plastic corners can be tapered, with L or F. shaped cross section, unequal, T-shaped profiles. Corner piece L.The shaped profile is the most commonly used compared to the others. Basically it is masking of gaps in the joints of materials, edging sheet material, the corner connection trim.
As a rule, the angle between the shelves of the corner is equal to 90 degrees, and they have sizes: 1010, 1515, 2020, 2525, 3030, 4040, 5050 millimeters. Such corners are most often used for window and door jambs. If it is installed in a place with significant influence of environmental factors, it is better to use nooks of 20 mm and more. and above. Smaller size corners 1010 and 1515 are usually used for finishing work indoors, they integrate smoothly into the general design.
Plastic corners with unequal cross section are used for finishing arches. The sizes of these corners 517, 1020, 1525 mm. Angle with such a cross section is easier to fix, they are flexible enough and easily maintain the desired position, creates a smooth line to trim the bend and a smooth edge. On one side of such corners is a cross section, allowing to make a line for a trimmer of necessary degree.
Corners of PVC vary, depending on the type of finishing work. So they can be external and internal. Outer corners have an angle of 90 and 105 degrees. When using the corner, with an angle of 90 degrees, for the window, one bar remains in sight, the other is inserted into the gap of the window frame. Corner, which has an angle of 105 degrees, is mounted two strips outward.
Self-adhesive plastic corners are especially popular. They are quite versatile, t.к. no need to purchase glue. They also have an increased ability to bend and unbend, providing easy installation and a perfect look. Another feature: these corners are sold in rolls, the length in a roll is 50 meters. This allows you to buy the necessary length and avoid joints.
How to mount plastic corners?
Firstly, note that before the direct installation of plastic corners on the windows it is necessary to wallpaper the room, paint, etc. That is, you can start fixing them only after all the finishing work is complete.
To install a plastic corner, you will need the following tools:
- assembly glue (liquid nails)
- masking tape (adhesive tape), and in a room with high humidity. silicone sealant
- Metal scissors or a hacksaw
- PVC nooks
Window finishing with plastic nooks and crannies consists of several stages. Consider each of them:
Depending on where they are used, plastic corners may be tangent, with L or F. shaped cross section, unequal, T-shaped profiles. Angle L.Shaped profile is most often used compared to the others. Basically, it is masking of gaps in the joints of materials, edging sheet material, the corner joint trim.
As a rule, the angle between the shelves of the angle is 90 degrees, and they have sizes: 1010, 1515, 2020, 2525, 3030, 4040, 5050 millimeters. Such corners are most often used to decorate window and door soffits. If the corner is installed in a place with significant influence of environmental factors, it is better to use the corners with the size of 20 mm or more. and above. Smaller corners 1010 and 1515 are usually used for interior decoration, they blend seamlessly into the overall design.
Plastic corners with unequal cross section are used for finishing arches. The sizes of such nooks are 517, 1020, 1525 mm. Angle with such section is easier to fasten, they are flexible enough and easily keep the necessary position, creates a smooth line for a bend trimmer and an even edge. On one side of such angles has a section that allows you to make a line for the trimmer of the required degree of bending.
PVC corners differ, depending on the type of finishing work. So they can be exterior and interior. Outdoor corners have an angle of 90 and 105 degrees. When using a corner, with an angle of 90 degrees, for the window, one bar remains in sight, the other is inserted into the gap of the window frame. Corner, which has an angle of 105 degrees, is mounted with two shelves outward.
Self-adhesive plastic corners are especially popular. They are quite versatile, t.к. no need to buy glue. They also have an increased ability to bend and unbend, ensuring easy installation and a perfect look. One more specific feature: such corners are sold in rolls, the length in a roll is 50 meters. This allows you to buy the necessary length and avoid joints.
Plastic corners on the slopes: easy to assemble!
Plastic corners are the most modern and incredibly popular way to decorate plastic windows. The entire installation process is not difficult, and a person with no special skills can handle it. For convenience, the entire installation procedure can be divided into three main steps:
- Preparatory work with the surface to be treated;
- corner preparation;
- the proper installation of the already prepared plastic corner on the surface.
If you are confident that you can do all the work yourself, then using the simple tips you will easily accomplish what you have in mind.
Marking on the ceiling to perform the corner on the baseboard
There are different ways of how to properly make a corner on the ceiling skirting. Some are easier to perform, others are more difficult. One such way is to mark the baseboard on the ceiling. True, it is not very convenient to cut the baseboard on the weight, but in accuracy this method is not inferior to all the other. Before cutting the skirting on the ceiling, it is applied to the surface, with all the flaws and irregularities of the walls, as well as the size of the corners are immediately taken into account.
Let’s consider in detail how to properly make corners on ceiling baseboards, using this technique:
- First, the two mating baseboard strips must be cut at an angle of 90º;
- One of the blanks is pressed against the wall, and its end rests against the opposite wall. Then the contour of the workpiece is drawn on the ceiling.
- In the next step, take the second plank and in the same way press its end to the wall. Outline the line for the trimmer.
- At the intersection of the lines obtained put a point at which to further trim the skirting boards.
- Then each of the strips again in turn is applied to the ceiling and transferred to the blanks of the point of cut.
- From this point in the corner of the plinth draw a diagonal line to trim the cut.
According to the lines obtained, cut off unwanted parts of the skirting boards, then dock the adjacent segments, checking the correctness and completeness of the fit. “How to cut the corner of the ceiling plinth. simple and correct ways”.
It is worth noting that this method is more often used for internal corners.
Using the template of the plinth
To cut the baseboard in the corner on the ceiling as evenly as possible, instead of using a normal sketchbook, you can use a paper, cardboard or wooden template. Two parallel lines are drawn on it, then the central point is found and any angle required is set off from it with a protractor. Before you cut the corner of the ceiling plinth without a ruler, it is worth rechecking the size of internal or external corners between the walls of the room, using the same protractor.
The principle of cutting corners with a template is similar to using a standard plier. In this case, the workpiece should be pressed to a parallel line and, having set the hacksaw at the desired angle, saw off the workpiece.
Polyurethane baseboards are the most expensive products. The high cost is due to a lot of advantages, including excellent resistance to moisture, high mechanical strength, reliability and elasticity. For most situations, this option will be optimal.
However, there are exceptions. polyurethane does not withstand temperature fluctuations well. If you place such baseboards in the kitchen near the stove, over time, polyurethane will deform and crack. Cutting such fillets is performed with a special knife, and there are no complications in the process.
Ceiling baseboards made of wood are different from their counterparts. Wood has a fairly large weight, which affects the weight of products from it. Skirting boards as a result are quite dense, very resistant to mechanical damage and solid, which allows you not to be afraid of accidental deformation during installation or slicing.
To trim a wood fillet, it is best to take a fine-toothed hacksaw designed specifically for fine work with this material. However, a good option would be a good quality metal skirting board.
How to make the inner corner of the floor plinth
Despite the fact that the rooms are usually a regular rectangle, their corners may not correspond to 90º. Perfect wall angles are usually all that builders and renovators have to dream about.
How to cut the corners of the floor plinth, if you are lucky, and your apartment has the right corners, then to cut the baseboard strips, you need to do the following:
The (good) chisel itself can be ordered HERE. Before ordering, make sure the width of your skirting board matches the maximum width of the jigsaw!
Using a plasterboard for the corners of the skirting boards
- Look for a 45º mark on the side panel of the tool, put a hacksaw into the corresponding groove and saw off the excessive part of the workpiece;
- Finely sand the cut edges with sandpaper.
Important! When cutting a skirting board, it is necessary to take into account its location (side of placement). It is recommended to saw a bit wider, in order to be able to fit the skirting board tightly later on. If you use a wooden skirting board, the joint is additionally treated with a special putty for painting.
What to do if the angle of converging walls is uneven?
Gypsum plaster and wide gum tape will help in this situation.
- At the junction of adjacent walls about 10 cm on each side is applied a small amount of plaster mortar.
- Further on a corner the reinforcing tape is applied, it is accurately pressed by a wooden bar.
Reinforcing corner for aligning the corner
Important! Work with a trowel very carefully so as not to disturb the position of the sealant tape, but also not slowly, so that the plaster does not dry out
How to join the outside corners of a skirting board
When the outer corners of the room are 90º, the procedure for cutting the skirting board is the same as for the inner corners. It is important to remember the future side of the trim when cutting. The ends of the joints of plastic skirting boards are closed with special plugs. If the cutting of the slats was not carried out very successfully, to correct this defect can be done with mastic, and then cover with a plug.
How to join the corners of the floor plinth, if they do not have 90º:
- First, the skirting board is attached to the first wall;
- We outline with a pencil (marker) all the boundaries;
- Do the same with the second baseboard, attached to the other wall;
- When marking should get a rhombus, as in the situation with the inner corner connection, only it will be located on the outside, respectively, the diagonal is a fishing line for trimmer cut blanks;
- After sawing the ends of strips we grind sandpaper;
- Next, install the skirting, the corner joints overlap the plug (for plastic products). The joints of the wooden skirting boards are sealed with a putty for painting.
Sawing the corner of the skirting boards (in the example, the skirting boards are ceiling tiles, but the technique for sawing the corner is similar)
After completing the attachment of the skirting boards in the corners, you can finally fix them around the room with self-tapping screws, liquid nails, finishing nails or a special adhesive.
Creation of the outer corner
Before making the outer corner of the ceiling plinth, you must perform appropriate calculations and measurements to perfectly cut the product. To do this, measure the distance that the part takes from the corner on the outside to the nearest wall.
On the reverse side of the product spend a line for the trimmer, outlining the required length, not forgetting that its upper part slightly protrudes outward. After completing measurements and counting the outer corner of the ceiling plinth, proceed to further work.
Tile is placed in the jig and neatly cut off. The adjacent baseboard is measured out like the previous one, not forgetting to leave a reserve. It is necessary to cut in a mirror reflection relative to the first segment.
Trying on the result
Knowing how to properly cut the corner on the ceiling plinth, will help to perform this work qualitatively. The received parts of the skirting boards are attached to the ceiling to see the result. The junction should be as even as possible, without gaps and nicks.
If a tight fit did not work at once, do not get upset. Use a regular knife to remove any imperfections. Use it to trim the edges of the product until you get the desired result.
Trimming of baseboards with the use of a chisel is used only when the angle between adjacent walls is 90 degrees, otherwise trimming has to be done by hand.
Plastic, wooden or fiberboard. which one to choose??
Convinced that the installation of angles is not just a whim, but a necessity, let’s study the construction market in order to make the right choice. These products are divided into types depending on the material from which they are made. So, the corner can be plastic, wood, bamboo, made of cork or fiberboard. Absolutely each type has its own advantages and disadvantages, let’s consider them in more detail.
Plastic corners are made by hot bending a sheet of PVC. Basically, they have the same shelf width. from 10 to 40 mm in 5 mm increments. However, there are asymmetrical pieces, such as 10×25 mm, but regardless of this parameter, the angle between the sides is 90 degrees. If it is necessary to transform the arched opening, it is done by means of a special flexible profile. Their advantages include a relatively low cost, they do not need to be painted, unlike the same wood.
The next type. corners made of cork. Such decorative elements are quite often used for arched openings, but this does not mean that their use is limited to this area. They can also be used to decorate soffits of various shapes. Cork has a number of advantages, including durability, fire resistance, practicality and environmental friendliness. In principle, this material has almost no disadvantages, except that if your pet wants to sharpen the claws on it, it will damage the surface.
Also noteworthy are wooden and bamboo products, which will always be a sign of good taste and will fit into almost any interior. In addition, we should not forget about their environmental friendliness. True, such elements are somewhat more expensive than their counterparts from other materials, and in addition often need to paint. Even with natural wood can be compared and a material such as wood-fiber board, but it costs much lower, because for its creation using wood dust.
Photo gallery: trim materials
You can see that the range is quite extensive, and there is a lot to choose from. But what to be guided by?? Of course, however we would like, but almost always the budget is limited. So first of all we have to proceed from our financial situation. As mentioned above, plastic products are quite reasonable in price, with their appearance is not much inferior to counterparts made of natural materials. But, besides price, you should also pay attention to the fact that these elements of decor in harmony with the design of the room.
For the arches, you should buy special multi-sexed arched corners, they perfectly maintain their position when bent. Keep in mind that the wider the sides of this element, the greater the load it can withstand.
Price of such plastic products many times less than similar from other materials, and this is a major plus of this material, which, coupled with almost eternal life makes PVC corner the most popular option for finishing lining and openings.
1.First, from the type and shape of the section, as well as the size of the shelves, the more they are, the more it costs to produce a plastic corner and the more expensive the product.
2.Secondly, from the method of attachment, self-adhesive corners are already adhesive, which is included in their cost.
Installation of corners on window or door soffits
Once you understand what such products are made of, what their features are, and you have decided on the choice, you should study how to install the corners on the slopes. Detailed instructions are given below.
What glue to use
In addition to the corners themselves, we also need adhesive composition, which will be used to mount the selected element. When choosing it, it is worth remembering that quite often, especially if you need to glue a narrow product, the glue leaks out from under it and, of course, gets on the walls. As a result, the latter can be damaged, which, accordingly, will have a negative impact on the appearance of the room as a whole. Therefore, you should choose an adhesive composition, the excess of which can be removed from the surface.
mostly the corners are glued on new soffits, but still check that the surface is relatively flat, because no decorations will be able to hide big bumps. It must be free of foreign objects like nails, self-tapping screws, etc. д. It is also necessary to degrease, for this purpose white spirit is suitable.
How to cut correctly
Before discussing how to mount the corners on the slopes, you should know how to cut them correctly. After all, this step of all is the most time-consuming and maybe even the most important, because it depends on how their edges will be joined, and this directly affects the aesthetic appearance of the entire room. It is best to perform trimming with a fine-toothed hacksaw. At first it is necessary to measure length of an aperture then we put marks on the corner so that the piece corresponded to this parameter. Then the part that will be adjacent directly to the slope, cut strictly on the marks, and the part that will be to the wall. at an angle of 45 °.
For trimming angle you should use a hacksaw with fine teeth
How to glue
There, finally, we got to the main issue, how to glue the corners on the slopes. However, before you proceed directly to the fixation, you should carry out, so to speak, trying it on. After making sure that everything is trimmed correctly, you can go on. Apply the adhesive solution on the inside of the corner, at the junction of the sides, with a spacing of approximately 10 cm. At this stage an indispensable helper will be a mounting gun. After that, quickly press the product to the surface and fix it in that position with painter’s tape. Start with the horizontal slope, and then proceed to the sides. Remove excess sealant from the surface of the walls with a damp cloth and allow to dry well. You can remove the tape only after 24 hours.
