When starting to renovate your house or apartment, you may be faced with the question - how and how to finish the arch? This is not an idle question, because arches as an element of interior design are becoming more and more popular every day.

In fact, making arches is a fairly simple procedure. If you follow the recommendations and be patient, then after a while you will be able to show off to your friends the arched opening you made yourself. So let's get to work.

Making an arch

In this material we present the manufacturing technology of plasterboard arches. In fact, there are several arch technologies, but drywall is the easiest material to work with.

To make an arch we need:

two sheets 12 thick
arched plasterboard sheet 6.5 millimeters thick
four guides and one rack profile
two reinforced arched corners.

We will make the arch according to the following scheme:

Arch made of plasterboard. Scheme

We cut two sheets of drywall exactly the width of the doorway.
On each sheet we draw a semicircle that forms the outline of the arch of the future arch. We cut out the resulting arches along the contour using a hacksaw or jigsaw.
On finished walls and the finished ceiling in the place of the opening we attach metal guides, retreating from the edge by 1.5 cm (i.e. approximately by the thickness of the drywall). For fastening we use self-tapping screws with plastic dowels, which we hammer into pre-drilled holes.
Using “flexible” self-tapping screws (3.2x25 mm self-tapping screws) and an electric screwdriver, we screw the sheets with the cut out contours of the arch to the guides. We tighten the screws in increments of 10-15 cm, recessing the cap into the drywall.
We measure the length of the arcs of our future arch. We cut the guide profile along this length, and using the cuts we bend it along the contour of the arc. We attach the profile inside the drywall.
To strengthen the structure along the inside of the arc, we add jumpers from fragments of the rack profile, which we fasten with the same screws to the curved metal guides.
We measure the length of the arc that forms the arch of the arch. Along this length we cut out a strip of arched drywall. The width of this strip is equal to the depth of the doorway.
Having bent the arched drywall along the required radius (it may have to be moistened with water), we attach the strip to metal frame using self-tapping screws.
Attaching gypsum boards to the profile

The resulting arch is completely ready for finishing!

There are many options for finishing arches. And, of course, within of this material It is impossible to consider absolutely everything. Therefore, we will focus on those options that you can implement yourself, without involving third-party specialists.

Decorating the arch with wallpaper

The easiest way is to cover the arch with the same wallpaper that you will use to cover the plastered walls with your own hands in the room being finished.

For this we need:

Wallpaper glue
Ruler and pencil
Brush
Scissors

First, prepare the glue. To paste an arch, we prepare it thicker than for regular wallpaper, so that it dries more slowly and does not harden in drops. The thick consistency will allow you to move the strip of wallpaper, achieving a complete match of the pattern.

Now let’s get down to the gluing itself:

The glued wallpaper must be carefully ironed so that no air bubbles form under it.

Finishing the arch with decorative plaster

Another way to finish an arch is to do it yourself with decorative plaster.

If you have chosen this particular finishing method, the work will proceed according to the following scheme:

To begin with, we plaster the plasterboard from which the arched opening is made. This is done so that the seams between the sheets of drywall and the massive part of the opening do not show through under the layer of plaster, and also so that the surface for plastering is as smooth as possible.

Pay attention! Decorative plaster is not paint, so you shouldn’t be too zealous in leveling. It is enough to cover significant irregularities

Decorative plaster arches

After the surface is completely treated with putty, apply a primer. the putty surface ensures reliable adhesion to the plastered surface.
After the primer has polymerized (this process takes from 4 to 24 hours), apply the plaster. Using a grater, sponge or spatula, we form a relief on freshly applied plaster.
Once the surface is completely dry, you can use special paint tools used for painting. decorative plaster, paints. If we used a plaster mixture tinted in the mixture, instead of painting, we can limit ourselves to applying a finishing protective layer or decorative metallics.

Decorating the arch with decorative stone

Cladding with decorative stone is one of the most spectacular, but at the same time, the most labor-intensive methods of finishing arches. The main difficulty in this case lies in finishing the arch and its vault with stone.

The material itself is quite practical and convenient: it does not require a perfectly smooth base, and this already eliminates some complex work for leveling walls with plaster or other material. However, finishing arches in an apartment with decorative stone is complicated by the fact that not only flat surface, but also inner side arches

Pay attention! If you have a plasterboard arch, then you need to choose it very carefully! A stone that is too heavy can cause deformation and even destruction of the arch.

We clad the arch with stone as follows:

We putty the surface of the arch to remove large irregularities and, after polymerization of the putty, prime it.
Preparing the mortar for laying the stone. The composition of the mortar may vary depending on what stone we will cover the arch with, but most often it includes cement, lime, sand and glue. There is also the possibility of installing the stone using “liquid nails”.
We lay the first stone from below, at the junction of the wall and the arch opening, adjust it to the level and press it tightly. In order not to pay attention to additional sealing of the corner in the future, the stones are on the plane and inner surface We fasten the arches with an overlap.
We cut the stones that will be attached along the arc of the arch along this arc, accurately maintaining its radius. Trimming can be done using cutters or corner cutters grinder. The cut must be sanded with a stone file.
We seal the seams between the stones with a special solution, trying to ensure that drops of the solution do not fall on the front surface of the stone.

Using the technology described above, the arch can be finished with your own hands using both artificial and natural stone. As a result, you will get an arch that will delight the eye with its original design for many years.

Plastering an arch or opening - do it yourself

We plaster the arch. We do the side parts as in the topic Plastering window slopes, but we leave some space on top.

On the slopes we mark the edge of the arch.

We reinforce the void - wire or thin reinforcement will do. You can use masonry mesh for armored belts.

From OSB, plywood, or plasterboard, we cut out two templates with the desired radius of curvature. We fix our templates on the wall using dowels.

We throw the solution into the void - you can put in a bottle. Pieces of brick will do. In order not to wait for the solution to set, add alabaster.

You will need a special polisher with a rounded side. To do this, you can take regular foam plastic and make curves using a block with coarse sandpaper.

When the solution hardens, remove the templates and finish the surface underneath them.

We rub in the voids and hollows that could not be filled due to the template.

That's all - the arch is ready. If you use a curly template instead of a rule, you can do something like this

Or something like that.

The artistic value of the data is debatable, but there is an opportunity to do so. Good luck in your work.

Let's start puttingtying the plasterboard arch

It is necessary to inspect and check the entire plane of the drywall before starting work, check the integrity of the sheets, and use any spatula in the places where the screws are screwed in to secure the drywall to the guides. The screw should not interfere, but if the spatula gets stuck on one of them, then it should be screwed inward by about 1 or 2 mm relative to the plane of the drywall. There may be other defects, please eliminate them if possible!

I. Apply primer to the arch

Take the KNAUF - Tiefengrund primer without opening the lid, mix by shaking the container.
Take the roller tray and pour the primer into it, after opening the lid.
Next, take a roller with a telescopic handle and a brush, coat all joints and places where the plasterboard is attached.
After applying the primer to the drywall sheets, you should wait a little for absorption.

II. We putty all the joints of the gypsum boards and the places where the screws are screwed in using Knauf - uniflot

After this, take a small container for stirring, pour Knauf-uniflot putty into it (do not stir immediately large number mixtures, because it sets quickly! Practice with a small amount first). Stir using a narrow spatula by adding water until a homogeneous mass without lumps is obtained. The mass should not be liquid or watery, it should be easily applied to drywall and not fall off!
Apply the putty, inserting it as deep as possible into the joint of the gypsum board, coat it on top and then apply self-adhesive fiberglass tape, pressing it into the putty and then leveling it using a 15 cm wide spatula.

Next, we putty all the heads of the screws that fasten the drywall to the frame, without using self-adhesive fiberglass tape, as well as all the junctions between the drywall and the walls.

Then we take perforated corner and attach it to all corners of the arch using a construction stapler. After this we putty the perforated corner.

III. Putty using Vetonit LR +, first layer

We take a larger container for mixing, pour Vetonit LR+ finishing putty into it (do not stir a large amount of the mixture at once! Practice with a small amount first). Stir using a drill with a mixer attachment by adding water until a homogeneous mass without lumps is obtained. The mass should not be liquid or watery, it should be easily applied to drywall and not fall off!
Now you can apply it to the gypsum board. For best result When puttingtying the surface, use a bright light bulb.
The first layer of Vetonit LR + putty should give the surface a smooth appearance as much as possible, but if this cannot be achieved, then points V and VI are for you!

After the first layer has dried (set), I recommend sanding it special grater and sanding mesh small size. For the best result when sanding a surface, use a bright light bulb, rubbing at different angles, you will be able to detect various defects and eliminate them in time!

IV. Apply the primer to the arch (the stages of applying the primer are described above).

V. We putty using Vetonit LR +, the second layer (the putty method is described above).

VI. Apply the primer to the arch (the stages of applying the primer are described above).

After that, you can start hanging wallpaper or painting the arch!

Thank you for your attention!

Interior decoration of premises with plasterboard is often accompanied by the problem of how to putty plasterboard. After all, in fact, it is absolutely flat and there is nothing to level on it. However, if you delve into the intricacies of the process, the characteristics of the material are revealed that force the master to carry out this process. We have to putty the ceiling, walls and everything additional designs like boxes, arches and columns.

How to putty plasterboard walls

Before answering the question of how to putty plasterboard walls, you need to determine what is required for this. First of all, you will need putty. There are several types of it, which are selected depending on the purpose of the room. For rooms with high humidity select a composition based on cement or polymers; for the rest, a mixture based on gypsum is suitable. Vetonit putties are a good finishing material.
They all dry quickly, so preparing a large volume of the mixture is not recommended. The preparation recipe and proportions are usually given on the packaging of the dry mixture, but can also be used ready solution, which is sold in plastic containers.

Before puttying, the walls are treated with primer. Its drying time is about 12 hours. It is not necessary to completely treat the entire surface. The process depends on the subsequent decorative treatment of the walls. It is important to carefully process the edges of gypsum boards (plasterboard sheets), especially if they are cut. Such joints require additional preparation.

Before priming, the edges are cut at an angle of 45 degrees to ultimately form a joint with a rectangular gutter. It is this that is filled with putty, which is leveled with a wide spatula. Also, the joints of the gypsum boards are subject to putty using screws. Their cap should not protrude beyond the gypsum board plane. If it is deeply recessed, the screw will need to be replaced. The screw heads are puttied in two layers. The first is applied from top to bottom, the second - from right to left or vice versa.

How to putty a plasterboard ceiling

The ceiling is puttied if it is to be covered with plaster or painted. If it will be mounted suspended ceiling, then this procedure is not necessary. The preparation process is similar to working with walls. In this case, the putty is applied in two layers. First, the joint is filled with putty, leveled, then a second one is applied and re-leveled. It is also recommended to use serpyanka mesh. This painting mesh comes in two types: regular and adhesive.

The second is glued to the prepared surface at the joint of the plasterboard, after which it is treated with putty. The first one is attached after applying the first layer of the mixture. The mesh is pressed down with the flat surface of the spatula, while simultaneously leveling the putty underneath. After this, the next layer is applied, which masks the fiberglass mesh itself and smoothes the transition between it and the gypsum board. Instead of a grid, it is allowed to use masking tape on paper based or paper tape glued to PVA. Anyway top layer putty should be as thin as possible, no thicker than 1 mm.

How to putty corners of drywall

Particular difficulties arise when processing corners. Internal and external corners are processed in two various techniques. Internal corners are processed by gluing a strip of mesh to each corner plane, after which the joints are leveled with a second layer of mortar.

Aluminum profiles are used to process external corners. Most often, simple corner perforated profiles are used, but there are also profiles equipped with a sickle tape on each plane. Such profiles are attached to a still damp layer of putty and pressed in from above. Excess solution is distributed from above to level the surfaces. A layer of putty is also applied on top.

If the corners have a rounded shape, for example, when forming curly cutouts, sides and arches, use a plastic profile rather than a metal one. It fits tightly to curved lines and adheres easily to putty. If there is no such thing, use the same one aluminum profile, but in the place where the trajectory changes to a curve, transverse cuts are made on it. If the corner has a complex shape, then trimming is done on both planes, but more often trimming is required only on one side. The frequency of cuts varies based on the trajectory.

How to putty drywall for painting

If drywall is puttied before painting, this process is treated with the greatest responsibility, because Even under a thick layer of paint it is difficult to hide the slightest errors. The disadvantages are most noticeable when finely dispersed paint, such as acrylic, is used.

IN in this case It is impossible to do without fiberglass mesh at the joints in order to obtain an imperceptible transition between different gypsum boards. The use of a mesh will avoid cracking of the solution. All irregularities, including those resulting from unsuccessful installation or unloading, namely cracks, chips and depressions, must be puttied. After the solution has dried, the surface is sanded. To do this, use 0-grit sandpaper. Skin with large size grains may damage the surface.

Do I need to putty drywall?

The need to putty drywall is determined by only one factor - decorative properties finishing coating. If, for example, you use it as a visible layer ceramic tiles, then this process can be omitted. But if another type of coating is used, such as wallpaper, paint or decorative plaster, its use will be mandatory.

Putty allows you to make a monolithic wall from separately sewn gypsum boards, regardless of the characteristics of its shape. At the same time, it protects them from penetration under the outer layer of moisture, which can destroy it. Also, in addition to the joints, the heads of the self-tapping screws connecting the wall, frame and gypsum board must be puttied, because During operation, they can cause rust to appear on the surface. Well, how to putty drywall is described above.

Spatulas – large for working on open areas and small, for processing seams;
Starting putty, finishing putty and for sealing seams;
Reinforcing tape;
Electric drill with a nozzle for stirring the solution.
Primer.

Take a small portion of putty from a container with ready-made composition, or prepare a limited amount from a dry mixture. Using a spatula, apply thick strokes between the screws and smooth them, carefully pressing the solution into the perforation holes to ensure sufficient adhesion to the base. In this case, the mixture should also lie on top of the corner, grabbing it to the surface of the drywall.

When creating a mixture it is necessary achieve a uniform consistency, for this, use a drill with a mixer attachment, apply the solution with a small spatula onto a large one, and then rub it over the surface of the plasterboard. A plasterboard arch does not have to be an arch in the standard sense; it can be installed not only in doorway, but also, for example, in the middle of the room, she makes the interior design unique. We glue the edge of the plasterboard arch with serpyanka, or use a special arched corner, and fasten it with a construction stapler. It is necessary to strictly ensure that the surface to be finished with putty does not protrude as a bump and is on one horizontal level with wall and arch.

Excess material is carefully removed with a special plasterboard knife. Leveling should be done while the mixture is still wet; after drying, it will be impossible to smooth out the protrusions.

How to putty drywall

When conducting finishing works Craftsmen are often faced with the question of how to putty drywall. This question is relevant, since today this material is very widely used in the decoration of residential premises and work with it is carried out constantly. To bring the surface to a perfectly smooth state and prepare it for decorative processing, you need to rub it. This is done using sandpaper or a special abrasive mesh. Tip: the primer should be applied before each layer of putty, that is, if the surface is putty again, then it is necessary to go through the previous layer with a primer.

I must say that this DIY work requires some efficiency. You can stretch the surface putty in just a few steps. It can be secured with screws, or directly with putty.

For external corners special decorative round corners are used or metal corners. In order to understand how to putty a plasterboard arch, it must be said that a wider plastic flexible corner is used here. It is also applied directly under the putty.

When carrying out finishing work, craftsmen are often faced with the question of how to putty drywall. This question is relevant, since today this material is very widely used in the decoration of residential premises and work with it is carried out constantly.

In what cases is putty necessary?

Creating structures from plasterboard can be worn by the most different character, but in all cases this material needs putty.

Some usage examples should be given:

Wall decoration in residential premises with subsequent decorative treatment.
Creating ceilings in various rooms.
Creation of structures performing various household and decorative functions.

In all of the above cases, you must know how to putty drywall and process all the seams that form where the sheets join.

Why putty drywall?

You need to understand that drywall consists of sheets of cardboard, between which a layer of gypsum is laid. If you glue wallpaper directly onto drywall, then later it will no longer be possible to replace it with others. The glue will saturate the cardboard layer, and the wallpaper cannot be torn off in any way.

In the case of applying paint or decorative plaster, putty is even more in demand. Even the slightest flaws in the structure and surface are visible under these types of finishing materials, so it must be prepared for painting. The rest of the article will discuss how to properly putty drywall.

Ceiling or walls

It must be said that the principles of puttying a plasterboard ceiling are not much different from the same process in the case of walls. The only difference in this case is the labor intensity of the work. It is clear that working on the ceiling will be associated with great inconvenience and its implementation will require more strength and skills. Whereas working with walls will be easier and will not take as much effort.

Preparing material for putty

Start

Before you begin, it is necessary to carry out some preparation of the material.
From the entire surface of the drywall you need to sweep away or wipe off dust and construction waste.
After this, it is necessary to prime the entire structure.

This measure will create a thin crust on the surface of the cardboard layer, and it will absorb less moisture. Only after the primer has completely dried can you begin to putty.

Advice: the primer should be applied before each layer of putty, that is, if the surface is puttyed again, then it is necessary to go through the previous layer with a primer.

Choice of putty

First of all, you need to calculate the approximate amount of putty needed. You need to purchase this material with some reserve, but you shouldn’t take too much either. Drywall putty in most cases is a dry mixture that must be diluted with water. It should be noted right away that the result should be a very liquid mixture like sour cream, so the material consumption is small.

Tools

If everything is quite simple with the material, then with the choice of tools the situation is a little more complicated. For this work you will need both power and hand tools.

A list of them should be provided

1. A hammer drill with a nozzle for stirring solutions.

2. Several types of metal spatulas:

wide
average
narrow.

3. Sandpaper or a special grouting abrasive mesh.

4. Construction knife.

5. Roller or brush for applying impregnation.

6. Metal building rule.

7. Self-adhesive “serpyanka” tape for processing seams.

Solution

How to prepare the solution

In order to make a high-quality putty mixture, you need to carefully read the instructions on the material itself.
Traditionally, putty is diluted as follows: take a bucket, the size of which depends on the volume of work, and fill it a quarter with water.
The putty is gradually poured into the water in portions and mixed.
The mixture should be thick enough to resemble sour cream.

To prevent lumps from forming, mix the solution using a hammer drill with a special attachment. Now you need to leave the prepared solution for 3-5 minutes and mix it again. After this, the entire resulting mass must be worked out, since it is no longer possible to beat the putty again - it will lose all its properties. Since the price of this material can vary, you should be careful not to waste it in vain.

Advice: if a simple drill or hammer drill is used to mix the solution, then you need to put it in reverse mode and at minimum speed so that the vortex flow emanating from the mixer is not upward (clockwise) but downward (counterclockwise). Then the putty will not scatter all over the walls.

Seam processing

Preparing for work

Before you start or another finishing material, it is necessary to go through all the seams of the structure with a special mesh tape - “serpyanka”. This must be done without fail, since such a measure will strengthen the entire structure and prevent the formation of cracks.
The mesh is sold in convenient rolls and is self-adhesive so it is easy to apply.

If you take your time and are careful, this work will not take much time; instructions are given below:

You should also start putting putty by treating the seams and screws; these places are treated first. Sometimes craftsmen immediately putty the entire surface once and immediately rub it down. This approach generally has its place, but if there is a desire for quality and reliability, then it is better not to rush.

putty

How to apply putty

After the putty areas of the seams and screws have dried, you can proceed to the next stage. You need to scoop up a portion of putty onto a large spatula.
Place it vertically on the surface of the drywall and begin to stretch the putty.
You need to have two spatulas in your hands, a wide one and a second one narrower, so that you can pick up excess putty.
The movements of the spatula should be wide and sweeping, evenly distributing the putty over the surface.

I must say that this DIY work requires some efficiency. You can stretch the surface putty in just a few steps.

Nuances

To make the surface more even, you can go over the putty with a metal rule, you just need to accurately and evenly distribute the pressure. After the entire surface of the drywall has been covered with putty, you must wait one day. After checking that the surface is dry, you can carefully cut off the traces left by the spatula with a small metal spatula.

Please note: many people think that after applying putty they should not open the windows, since a draft can spoil the result of the work - this is not true; the putty is not afraid of drafts and the room can be safely ventilated.

Grout

To bring the surface to a perfectly smooth state and prepare it for decorative processing, you need to rub it. This is done using sandpaper or a special abrasive mesh.

You need to evenly cover the entire surface with sweeping movements.
Then wipe off the resulting dust with a dry, clean broom.
You can determine whether the putty surface has completely dried by its uniform color without the presence of dark damp spots. See photo:

Advice: if the ceiling is rubbed, then do not forget to wear safety glasses and a mask to protect yourself from dust.

Joints and corners

Corners and all kinds of joints that are present in any plasterboard structure deserve special attention. To strengthen such connections, special metal corners of various modifications are available for sale. To ensure that the internal corner of the drywall structure is reliable, a special internal corner is placed in it before puttying.

It can be secured with screws, or directly with putty. For external corners, special decorative round corners or metal corners are used. In order to understand how to putty a plasterboard arch, it must be said that a wider plastic flexible corner is used here. It is also applied directly under the putty.

Decorative finishing

When all the stages of putty are over and the result is a perfectly smooth ceiling or walls, you can begin decorative finishing. If you subsequently want to stick wallpaper, no matter the ceiling or wall, the surface must be treated. You can cover the entire surface with a primer, or you can use wallpaper glue. But it should be noted that such work should only be done on a completely dry wall.

Conclusion

If there is a desire to create high-quality surface under finishing, you should approach the putty process with all responsibility. A careful selection of materials and tools, as well as a diligent attitude to work will allow you to achieve good result. The video in this article will answer all remaining questions.

When working with drywall, the most labor-intensive part to perform is the arched ceiling, but finishing the arch also requires a lot of effort. For work, it is best to use putty, since the surface of the drywall is quite smooth and a large consumption of material is not expected. In addition, the putty will provide a high-quality, durable coating and protect the surface of the sheets during subsequent repairs. If this is not done, in a few years when you shoot decorative coating To carry out a new repair, part of the cardboard will be peeled off along with the old finish.

The order of finishing the arch

The most problematic place when finishing an arch with your own hands is its edges, which, as a rule, have chipping defects and other unpleasant defects. In order for the arch to look neat later, its edges must be aligned and secured.

For this purpose, a metal profile or special linings on the side surfaces are used.

Leveling the surface of the arch before finishing

As a rule, an arched ceiling is installed between two walls. Therefore, the first thing that needs to be done when finishing arches in an apartment is to smooth out its transition to the wall surface. We level the joint with starting putty between the plasterboard forming the arch and the wall. If you made an arch in, then you will not have to align the junction.

We close the heads of the screws holding the drywall to the arch frame.

To level the arched arc, we use a spatula slightly wider in width than the overlap.

The result should be an arc that smoothly turns into the wall.

On the sides we begin to putty the arch from top to bottom. We apply sickle tape to the joints of drywall and overlays to strengthen them.

To do this, apply the first layer of starting putty.

We lay the reinforcing mesh and secure it on top with another layer of mortar.

We also apply sickle tape to the edges of the arch and secure it to the mortar.

We glue the edge of the plasterboard arch with serpyanka, or use a special arched corner, and fasten it with a construction stapler.

Then distribute the solution evenly over the surface.

All this work, as a rule, is carried out with starting putty, which has greater adhesion to drywall, and its cost is significantly lower than the price of finishing putty.

If necessary, the solution can be applied in several layers with a thickness of each no more than 0.5 cm. In this case, each layer must be dried and treated with a primer. After applying the latter, it also needs to be dried. The starting putty is applied until the surface of the wall and the arch form one whole without differences in level.

Then you should wait for the material to dry completely, level the surface with sandpaper and prime it.

Depending on the subsequent finishing of the arch, it is possible to apply the last layer of . Usually it is performed during subsequent painting of the surface. If wallpaper is used as decorative decoration for arches, decorative stone or other materials for which ideal smooth surface, applying finishing putty is optional.

When carrying out work, follow several rules:

When covering the holes, apply a little more than necessary, as the solution may subsequently dry out a little. So, it’s better to have a small bump that can simply be removed with sandpaper than a depression that requires additional sealing.
For leveling, it is permissible to apply 3-4 layers of putty; each layer must dry for at least half a day.
The seams are sealed extremely carefully, with the mortar being pressed into the gap between the joints. Just as in the case of holes, it is better to apply a little more than necessary, and then remove the excess with sandpaper.
