Preparing walls for wallpapering occurs in stages. Thanks to this, you can not only bring the walls into a perfectly flat state, but also ensure tight adhesion of the wallpaper to the surface being pasted.

Experienced craftsmen know that before wallpapering it is important to properly prepare the walls. The quality of subsequent work performed depends on this circumstance. These actions do not require skills or knowledge; beginners can cope with them. However, you need to be patient and familiarize yourself with the recommendations below.

Why prepare the walls before gluing?

The main reasons why it is necessary to prepare the surface of the walls before wallpapering are as follows:

1. The quality of adhesion of panels to the surface of walls increases. If the surface to be pasted is porous, the wallpaper will not stick to it sufficiently long time. The first step is to eliminate all flaws on the walls.
2. Surface roughness. Even the densest and thickest wall coverings will not hide visible irregularities (bumps, potholes).
3. Fungus or dampness may appear. Fungi and mold most often form on untreated surfaces. This circumstance in most cases concerns external walls that have direct contact with the street.
4. The connecting ability of materials improves, due to which the wallpaper on wall surfaces will last longer.

Step-by-step preparation of walls before gluing

There is a designated preparatory work plan before wallpapering, which includes:

1. Primary treatment of the surface to be glued. After removing the old coating, it is important to primary processing. This includes removing nails and screws from the wall, as well as removing baseboards.
2. Repairing dents and holes. Chips, potholes and other defects are often observed on the surface to be pasted. It is extremely important to remove them before gluing. For these purposes, cement or putty is used.
3. Applying a primary primer will help glue the microparticles to the wall, after which you can begin plastering work. This rule should never be neglected.
4. Plastering the surface requires some skill, especially if the surface of the walls is curved. At the initial stages, beacons are installed according to the level, after which a layer of plaster is applied, which is leveled with guides.
5. Repeated primer is applied after the plaster has completely dried.
6. Putty is applied to the surface in the case when, after plastering work, the difference in the unevenness of the wall is no more than 5 mm. In this case, 1 layer of putty is sufficient.
7. Sanding the wall surface is carried out at the final stage of work before gluing it. After sanding, the surface becomes perfectly smooth.

Preparing walls in a new building

Preparatory work in this case takes a certain amount of time, since the walls in a new building can be completely “bare”. Further preparatory work is divided into the following stages.

Firstly, a spray up to 9 mm thick is applied. The consistency should resemble thick sour cream, which will fill all the potholes, cracks and irregularities.

The consistency of the spray directly determines how exactly the plaster will lie on the walls. If the consistency is slightly thick, reminiscent of sour cream, the plaster will lie perfectly.

Secondly, the surface to be glued is primed. The thickness of this layer should not exceed 6 mm. However, when urgent need Apply 2-3 layers of primer.

Thirdly, it is applied last layer plaster (covering), the thickness of which does not exceed 4 mm. This stand is easily rubbed, which will give the surface additional evenness.

How to cover the walls

Any defects on the surface to be glued are first covered with starting putty. After this, the surface is cleaned of additional contaminants and primed. By the way, you can blow out large defects using polyurethane foam. This material will cope with this task perfectly.

After drying starting putty It is necessary to sand the surface thoroughly to eliminate unevenness. Afterwards one or several layers of putty are applied.

Finishing with plaster yourself

To plaster the walls in your home, you must adhere to the following work plan:

1. A 5 mm layer of plaster is applied over the entire surface of the wall. All defects and cracks are covered. Before this, the wall surface is slightly moistened for greater adhesion to the plaster.
2. After the first layer of plaster has dried, a second one is applied. Special attention Care should be taken to level the finishing layer.
3. The last applied layer should not exceed 3-4 mm. It is used to grout the surface, which gives it perfect evenness.

The lining is done using a special spatula, with which the solution is taken from the prepared container and applied to the surface to be pasted. The plaster is spread with smooth movements using a trowel.

Requirements for a flat wall

The structure being pasted is clean and uniform. To make sure of this, experienced builders glue a piece of tape to it. There should be no dust or grains left on it.

There should also be no oil stains, soot or rust on the surface. Otherwise, they will definitely appear on the wallpaper, which will negate all the work. Such stains can be covered with nitro varnish. Lime stains also need to be removed. Wallpaper glue is not absorbed by lime, which can cause the wallpaper to swell later.

How to properly prepare a brick wall after removing old wallpaper?

Preparatory work begins with applying a liquid plaster solution.

This is called a spray whose thickness should not exceed 3 mm. Then the base layer is applied plaster mortar(priming).

The solution has a fairly dense consistency, and its thickness reaches 6 mm.

If it is necessary to increase the thickness of the layer, then it is advisable to apply the primer in several layers. On last stage To prepare the walls, a third layer is applied, the so-called finishing layer (covering).

What is it processed with?

IN damp areas There is a very high probability of mold and mildew growing on the walls. In this case, they are treated with the following means:

1. Cover the surface with a solution of bleach. As a rule, 200 g of lime are diluted per 1 liter. water. Before gluing, all walls are treated with this solution, which will help prevent the formation of unwanted elements.
2. Fungicide treatment. Today you can purchase special adhesives that contain a fungicide. In this way, you can combine the process of wallpapering and wall treatment.

Technology for finishing plastered brick walls

Preparatory work begins with removing the old finishing material. For these purposes, you can use a spatula after moistening the wallpaper with water. It is very important to allow the finishing material to get wet so that it is easier to remove with a spatula.

After cleansing brick walls they are examined for chips, gouges and other defects. If any are present, they are sealed with plaster solution.

If sections of old plaster raise any doubts in terms of reliability and strength, it is better to remove them using special tool and apply a layer of new plaster.

Also, before gluing wallpaper, you need to thoroughly clean the surface of the walls from visible dirt and dust. If there are visual unevenness on the surface, the plaster is rubbed down with sandpaper.

On final stage work, the surface to be glued is primed, after which you can begin gluing the finishing material.

Preparation for gluing plasterboard surfaces

Before gluing the finishing material onto the drywall, it is advisable to cover it with a thin layer of putty and seal the visible seams between the sheets. You also need to hide the heads of the screws that were used when installing the drywall sheets. They are recessed and covered with mortar.

Removing old paint

To remove paint from a surface, you can use several proven methods:

1. The paint is drying construction hairdryer, after which she is without special effort removed with a spatula. This method requires the use of a special respirator, since toxic substances are released when the paint is heated.
2. The painted surface can be cleaned using a grinder or a grinder. In this case, it is important to use eye protection.
3. Using a flush mixture is the most effective method. However, when working with chemical active substances you need to be extremely careful.

Features of the preparation of plastered walls

If the walls are already plastered and have a fairly smooth surface, it is important to pay attention to the presence of stains. They may be the result of fungus, water leaks or rust.

Only after these unwanted stains have been eliminated can you begin wallpapering. Otherwise, these stains will certainly appear on the surface of the finishing material. Experienced builders It is recommended to cover them with regular food foil.

The need for ground work

There are a number of reasons why it is imperative to prime the walls. These include:

1. By impregnating the surface with a primer, it will be possible to obtain a binding element. The surface to be pasted will be free of dust and will stop crumbling.
2. This will prevent the appearance of mold and mildew.
3. The primer will fill microcracks on the surface of the wall, making it much stronger.
4. The primer increases the level of adhesion.

The primer material is best applied to the surface to be glued using a roller. Hard-to-reach places can be treated with a brush. If the composition is absorbed by the wall, another 2-3 additional layers are applied.

When can you glue?

It is recommended to cover the walls decorative material only after completing all of the above work, which includes:

• eliminating visual elements on the surface;
• primer;
• plaster;
• putty.

Once the walls have a perfectly flat surface, you can begin gluing.

In addition to surface preparation, it is also necessary to observe temperature regime– it should be no lower than 5 degrees Celsius. Before gluing, you need to tightly close the windows and doors in the room to prevent drafts.

Preparing the surface for gluing is not too difficult task, as it may seem at first glance, but it must be done. The main thing for these works is to use high quality material, show attention and patience.

With all the diversity of modern finishing materials, wallpapering walls remains the easiest and most inexpensive way to update your interior. Vinyl and paintable, photo wallpaper, glass wallpaper and liquid wallpaper - the choice is yours. Preparing walls for wallpaper is the most important stage. Do not be tempted to stick new wallpaper on the current one, or on a painted wall: the old coating will inevitably crack, swell, and ruin appearance rooms. In old housing stock, the walls are not perfectly even, and the angles are far from straight. Invest a little money and effort in preparing the surface, and you won’t see how the new wallpaper deforms along with the old ones, or repeats the curvature uneven walls. Preparation is divided into several stages.

Dismantling old material

If you are going to update the interior where wallpaper was previously pasted, then you need to remove it. Turn off the power to the room to avoid electrical injury: when removing wallpaper, you will use sharp tools and wet the walls. Lay newspapers on the floor, remove furniture, or cover it with film. Removing old flooring is a messy and time-consuming process, but it can be made easier by knowing a few tricks.

• Find a section of the wall from which the wallpaper separates well. Pry the canvas with a spatula or knife and gently pull. There is no need to pull sharply, the old coating has become fragile. It’s good if you can remove the finish in entire strips, but most likely you will come across areas of the surface where the wallpaper is held very securely.
• Firmly glued wallpaper can be removed by first soaking it. Treat the surface warm water from a spray bottle or roll with a roller dipped in hot water. Remove the soaked coating with a wide spatula.
• Before soaking washable or vinyl wallpaper, roll them with a roller with metal spikes, this will destroy the moisture-resistant film. If you don’t have such a tool, make cuts on the surface with a sharp knife.
• If the old coating was glued to PVA, you can remove it using laundry soap. Grate the block, add three liters of water and bring to a boil. Treat the walls with a roller or sponge; after 20 minutes you can remove the wallpaper.
• Vinegar dissolved in hot water will cope with both PVA and construction adhesive. Dissolve a crushed piece of laundry soap and 400 ml of vinegar in a bucket of boiling water. Treat 1.5-2 m 2 of wall, after 20 minutes start working. If some areas do not lend themselves, they will have to be cleaned with a wire brush or moisture-resistant sandpaper.
• After removing the wallpaper, wipe the wall with a sponge soaked in clean water, this way you will wash away small particles of paper, residual glue and detergent.
• If old glue turned out to be of very high quality, treat the surface with steam. Place a wet cloth on the wall and iron it maximum power. An iron with a steam generator or a household steamer will cope with this task even better. After removing the coating, dry the walls to prevent mold from appearing.
• IN construction stores You can buy a special remover. Apply it to the walls, leave for 2-3 hours, then remove the wallpaper with a spatula or wide knife.

Removing old paint

Oil-based paint forms a smooth surface with poor adhesion, while water-based paint will begin to bubble under the influence of wallpaper glue. Oil paint can be removed using a hair dryer and a spatula, or washed off with a special solvent old paint. The water emulsion can be soaked soap solution and peel off with a spatula.

Surface priming

After removing the old coating, the walls need further processing. Regardless of what the next stage of work will be, you need to prime the surface, which will allow you to:

• Reduce wallpaper glue consumption;
• Increase the service life of the finishing coating;
• Give the surface uniformity;
• Improve adhesion.

Select a primer that matches the wall surface. Acrylic is intended for putty and plastered walls, alkyd for wooden ones. The primer is applied using a construction roller; in the corners you should use a brush.

After the first layer has completely dried, apply the second. Walls coated with primer are smooth and slightly sticky.

Plastering the surface It is necessary to carry out in cases where there is significant unevenness walls Inexpensive plaster mixtures are produced on the basis of cement or gypsum. It is easier to work with gypsum compounds, they are more plastic, have a fine grain, but are not intended for rooms with high humidity . Acrylic and latex compounds

can be used in any room, but they are quite expensive, so they are used as putty to smooth out small irregularities.

Operating procedure

• Install level construction beacons on the pre-primed wall. Follow the manufacturer's instructions - the packaging indicates the minimum and maximum layer thickness and complete drying time.
• Use a trowel to spread the plaster mixture between adjacent beacons.
• Using smooth movements from bottom to top, and from left to right, using the rule, stretch the plaster.
• Add the mixture to the resulting voids, and remove the excess with a spatula..

After the walls have dried, remove the beacons and plaster the places where they are installed. It is impossible to leave beacons in the thickness of the plaster; over time they will rust and stains will appear on the wallpaper

If smoothing and glossing were not carried out during the plastering process, the surface will be grainy and uneven; wallpaper cannot be glued to such walls.

Puttying the surface

After the plaster has dried, prime the walls and start puttingty. This procedure is carried out in one or several stages, depending on what wallpaper is chosen for covering the walls. Thick vinyl wallpaper with a pronounced texture does not require a perfectly smooth surface. To cover walls with thin and smooth wallpaper, you will have to apply both base and finishing putty. The finely dispersed structure of the putty mixture evens out the grain size of the plaster layer.

Scoop the mixture with a short spatula, spread it evenly over the long one, and apply the putty forcefully over the wall using smoothing movements. After the solution has completely dried, sand the surface with 240 or 320 grit sandpaper. During sanding, dust is generated, which must be removed with a vacuum cleaner, and if it is very dusty, wipe the wall with a damp cloth. Be sure to prime the walls after sanding. Wallpaper can be glued to a dry surface.

Preparing walls in a new building

Apartments in a new building can be rented with plastered walls or “in concrete”. In the first case, check the quality of the plaster. Knock the walls. A poor-quality solution applied in violation of technology may crumble or crack. You need to get rid of such finishing - it will continue to deteriorate. When the strength of the plaster is beyond doubt, check the walls building level. If the walls are “filled up”, they will have to be leveled with a plaster compound.

If the surface passes the level test, take a two-meter strip and apply it to the wall in different directions. An error of 1-3mm does not need to be equalized. Depressions and bulges within 5-7 mm will have to be puttied. More significant differences require plastering. If your apartment has concrete walls, then additional insulation

can be used . The sequence of work remains the same: plaster, putty, sanding. Priming is done after each stage.

Preparing walls before applying liquid wallpaper

Liquid wallpaper is a dry mixture of cellulose and silk fibers, decorative inclusions, pigment and glue. Before applying to the wall, the dry components are diluted with water and applied to the wall with a spatula. Liquid wallpaper has a three-dimensional structure that will hide minor errors in the walls, but it is a fairly expensive material, so preliminary preparation of the walls will help save money and allow you to obtain a high-quality coating.

• Surface preparation is carried out by analogy with the preparation of walls for pasting with ordinary wallpaper, but has several features: Make sure that the wall is free of nails, screws and other metal inclusions that could rust over time.
• Rust stains will appear through the decorative layer, ruining its appearance.
• Cover the leveled surface of the wall with 2-3 layers of light water-dispersion paint to avoid spotting of the decorative layer. A concrete wall needs to be puttied with gypsum putty, it will give the wall an even and will hide all the imperfections. After the putty has dried, apply a primer in two layers, then water-dispersed paint in three layers.

Even inexperienced craftsmen can prepare walls for wallpapering.

Follow the instructions for the selected materials, follow the sequence of work and remember: an attempt to save time or money at the preparatory stage will result in the need for a complete redo of the repair.

An important stage of finishing work is preparing the walls for wallpapering, because the final result of finishing the room will depend on how correctly and efficiently it is done. Even the most expensive wallpaper will not look good or last long if applied to poorly prepared walls. In this article we will cover all stages of preparation and tell you how to prepare walls for different types of wallpaper.

Why do you need to prepare walls for wallpapering?

The purpose of preparing walls for wallpapering is to achieve surface quality that will satisfy the following requirements:

• Precise geometry. No wallpaper will hide the curvature of the walls; a high-quality finishing result can only be obtained with even planes and right angles. Dimensional accuracy is achieved, usually by plastering or plasterboarding.
• No defects, smooth. There should be no protrusions, even the smallest ones, on the surface of the walls. Depending on the type of wallpaper for which the surface is prepared, a certain number of small depressions may be present. How thinner wallpaper, the smoother the gluing surface should be. Smoothness is achieved by puttying.
• Low absorbency properties. If the material has high absorbent properties, then the wallpaper glue is absorbed into it, and the adhesion of the wallpaper to the wall turns out to be fragile. To reduce the absorbent properties of materials, a primer is used.
• Uniformity of color. It is necessary when the wallpaper is thin and the surface of the wall is visible through it. A white primer helps achieve an even tone.

Having fulfilled all these requirements, you will receive perfectly prepared walls on which the wallpaper will look good and stick firmly.

During renovations, preparing walls for wallpapering usually begins with removing the old finishing layer. The exception is when the old wallpaper:

• were glued to a well-prepared wall;
• have no stains of dampness or mold;
• holds tightly without bubbles or lags;
• paper;
• with permanent color;
• do not show through new ones.

In such cases, it is recommended to first test the application of new wallpaper on one of the corners. If everything is fine after a day, then you don’t have to remove the old wallpaper. To prepare the walls for gluing, it is enough to prime them twice with an hour break. In all other cases, the walls will have to be cleaned.

To remove old wallpaper, most often you have to soak it. Each type has its own methods for soaking.

It is easy to soak paper ones with warm water using a sponge or fur roller. Having carefully processed one strip, after 10-15 minutes you can pry up its edge with a spatula and remove it from the wall.

If the wallpaper is waterproof upper layer, then to soak them it is necessary that moisture penetrates the paper base. To do this, you need to break the integrity of the top layer. This can be done either using notches or using a needle roller. In this case, you must use the tool carefully so as not to damage the putty located under the layer of paper.

After soaking paper base the waterproof film is easily removed, and to remove the bottom layer you can use a steam generator, steam iron, or special means that dissolve paper.

Removing wallpaper from drywall has its own specifics, because it is difficult to peel the paper off the cardboard without damaging it. Inexpensive wallpaper glue will help make the task easier. Having diluted it a little thinner than the instructions require, apply it thickly to the wallpaper, wait until it swells, and scrape it off with a spatula.

Liquid wallpaper, in addition to being decorative, also serves as putty. In addition, they have long term services. Therefore, if they have lost their freshness, it is better to update them by painting them water-based paint. But if you are determined to remove them, you can do this using an industrial hair dryer or manually with a scraper after soaking with warm water and adding a primer.

Removing old paint

Old paint is usually difficult to remove, but preparing walls for wallpaper requires this. To do this, you can use one of the following methods:

• Treat the surface grinder or an electric drill with a steel brush attachment. This must be done in a respirator to protect against dust, which is generated in huge quantities with this method.
• Use a hair dryer to heat the paint, and when it swells, remove it with a spatula. In this case, it is necessary to ensure good ventilation, since when heated, the paint releases toxins.
• Use solvents. For large areas, this method is not recommended, since it is the most expensive and not environmentally friendly.

If the walls were painted oil paint and do not need leveling, you can remove only the areas with loose putty, and carefully treat the rest of the surface with coarse sandpaper to roughen it.

Plaster

Plaster is used for brickwork, as well as for walls made of other materials that require significant leveling.

Recently, instead of plaster, interior finishing with plasterboard is increasingly being used, since it allows, at the same time as leveling, to also insulate and soundproof the walls, and does not require continuous putty.

Plastering is done using ready-made dry mixtures, which are diluted with water according to the instructions. To dilute the mixture, it is convenient to use an electric drill with a mixer attachment. Typically used for brickwork cement-sand mixtures, For concrete walls More often they use cement-gypsum.

Before applying plaster, the wall is freed from fragile elements, cleaned and coated with a primer. Apply plaster in 2-3 layers, each previous layer must dry thoroughly before applying the next one.

Often, when finishing work, it is not plastering that is required, but the repair of old plaster. This type of work includes cleaning cracks, removing all weak parts, followed by priming and filling the resulting voids with plaster mortar.

Putty

While in many cases you can do without plaster when gluing wallpaper, putty is almost always necessary. The only exception is when finishing walls with plasterboard, where putty is used only at the joints of sheets and in places where they are fastened with self-tapping screws.

Procedure for filling walls:

1. Preparing the surface for putty includes clearing cracks and voids, thoroughly cleaning and removing dust from the surface.
2. Then the primer is applied using a roller and brush.
3. After the primer has dried, you need to dilute the starting putty mixture, rubbing the lumps until smooth.
4. The finished solution is evenly applied to the wall with a spatula, leveled and left for about 12 hours to dry.
5. The dried starting layer is primed.
6. After the soil has dried, the finishing putty mixture is diluted.
7. The finishing layer is applied and leveled.
8. After the finishing layer has dried, it is sanded with sandpaper, dusted off and primed.

After this step-by-step instruction completed, we can assume that the walls are completely prepared for wallpapering.

Primer

An important step in preparing walls is priming. The essence of this action is that the applied composition penetrates inside the layer, gluing its particles and forming a film on top that does not allow liquids to be absorbed into it. Thanks to this, the liquid component of the next layer is not absorbed into the previous one, but performs its function - the glue holds the wallpaper, the water from the cement mortar ensures its slow drying, etc. Without priming the layers, the quality of plaster, putty, and wallpaper will be very low, so neglecting this procedure is strictly not recommended.

When applying a primer, it is important that the layer on which it is applied is thoroughly dry.

In this case, the primer will be well absorbed and will perform its task efficiently. Sometimes it doesn’t hurt to apply 2 layers of primer. You can continue working with the primed surface only after it has dried.

How to prepare brick walls for wallpapering

Preparation for wallpapering brick walls includes all the steps described above: plaster, putty, primer. Please note that newly built brick house, as a rule, shrinks, which can last from 1 to 5 years. If you don't want to postpone Finishing work at least for 1 year, then it is better not to use it for the first finishing too expensive materials, because due to shrinkage, the need for cosmetic repairs may soon arise.

How to prepare concrete walls for wallpapering

If concrete walls have precise geometry, then when finishing them you can do without plaster. It is enough to widen the existing cracks in the concrete, remove all weak elements and protruding irregularities, and then seal the recesses cement mortar. After the applied “patches” have dried, the surface of the walls is puttied in two layers - starting and finishing, sanded, primed, after which any type of wallpaper can be glued to it.

Since concrete has high thermal conductivity and sound permeability, concrete walls are often finished with plasterboard, combining it with soundproofing insulation.

The easiest way to prepare drywall for wallpapering is to just fill the joints and recesses from the screw heads, sand and prime these places, and then prime the entire surface.

How to prepare the walls of wooden and frame houses for wallpapering

Wooden and frame house construction most often finished inside wooden clapboard, panels or block house. These materials are chosen to highlight the warm atmosphere of timber homes. But if you want, then why not cover the walls with wallpaper?

Preparing walls for wallpapering wooden houses may involve both applying plaster and putty, and covering the walls with plasterboard or other sheet material. IN frame houses The second option is mainly used.

Preparation of walls made of plasterboard and other sheet materials

As already mentioned, preparing for wallpapering plasterboard wall coverings is the least labor-intensive option. You just need to fill the joints plasterboard sheets using serpyanka tape, cover the recesses from the fastener heads with putty, after drying, sand the putty areas and prime the entire surface.

How to prepare walls for different types of wallpaper

The highest demands on the quality of walls are made when preparing for gluing thin and light-colored paper wallpaper, especially if they have glossy surface. In these cases, the wallpaper will emphasize the slightest unevenness, and if the wall underneath is not uniform in color, it will be noticeable. Therefore, you need to prepare the walls for hanging such wallpaper especially carefully, not forgetting to cover them with a white primer at the end.

When preparing walls for gluing dark wallpaper You don’t have to worry about the uniformity of the tone of the surface being pasted. Therefore, diluted wallpaper glue suitable for this type of wallpaper can be used as a primer.

Thick wallpaper allows you to be less critical of the quality of the walls and allows the presence of a limited number of small depressions on their surface.

Preparing walls for liquid wallpaper is simpler, since it does not require puttying. After all, liquid wallpaper combines the functions decorative covering and putties, they can be applied directly to plaster or a concrete wall, not forgetting to prime them first.

One of the most common materials for decorating apartments is wallpaper, sold in a huge assortment. The process of gluing walls is quite simple, but preliminary work should be done first.

Properly done wall decoration will help make the rooms beautiful.

Preparation for pasting walls

Decorating an apartment with wallpaper requires the right approach to this process and great patience. When covering the walls of any room with wallpaper, no special knowledge is required. You only need to choose the right surface required wallpaper and patiently glue them, so that you can then receive satisfaction from the work done.

The most important thing is preparatory stage, in which it is necessary to ensure that the walls are dry and smooth, without paint, lime, or wallpaper.

Wooden, painted, whitewashed, old wallpaper or newly built walls require an individual approach.

Finishing work must begin with the following important work:

1. Drive all the nails deeply, paint the heads, and then putty them and clean them.
2. Cover all seams and corners with a wide bandage or paper and putty.

Preparatory work includes 3 stages: getting rid of the old coating, eliminating all defects and priming the walls.

Features of preparation for main work

Apartments purchased for self-finishing require a lot of time to prepare the wallpapering of the premises. Wall finishing technology plastering works is carried out in several stages:

1. Apply the spray in a layer of 3-5 mm. The consistency of the solution should be like thick sour cream in order to connect to the wall and cover any unevenness.
2. Primer. The solution is prepared thicker and applied after the spray has dried. Layer thickness - no more than 6 mm.
3. Covering - the last layer of plaster of 2-4 mm to obtain a thin film.
4. Cleaning with fine sandpaper.

Much attention should be paid to the seams between the tiles. They need to be caulked, glued with paper, putty, and then sanded.

If you do not remove the old wallpaper, then later it may come off on its own. To begin preparatory work, the following building materials should be prepared:

• spatula (wide and narrow);
• roller, brush, spray;
• water;
• additional means: vinegar, graters, etc.;
• wallpaper remover.

The surface of the wallpaper should be wetted hot water. You can add vinegar to the water, which will act as an adhesive solvent. Those who do not count money can use special means, removing wallpaper. If there are oil stains on the walls, they should be painted over with nitro varnish, nitro enamel or sealed with thin aluminum foil.

Plastered walls must be tapped over the entire surface of the walls so that later this plaster does not come off under the wallpaper. For small damaged areas, repair and level everything, and for large damaged areas, the entire old plaster It's better to remove it.

Preparation wooden walls under the wallpaper is done using drywall or dry plaster leaves. Then the wall is primed.

Preparing painted walls

Preparation technology painted walls more difficult than what happens with similar work with wallpaper. It is very difficult to get rid of paint, especially oil paint. The use of special solvents and spatulas does not always help when cleaning the surface from paint.

You can remove the paint using a hair dryer and a spatula.

The hot air of the hairdryer bubbles the layer of paint, and these loose layers can be easily removed with a spatula. Using a grinder or grinding machine brings inconvenience associated with a huge amount of dust. In this case, protective equipment in the form of glasses and a respirator do not help.

In some cases, small hatchets are used to clean the walls, which are used to make notches, and then everything unnecessary is removed with a staple. After this work, the walls are cleaned of dust and dirt with a damp cloth or sponge and dried.

An effective way to finish a painted surface is to use a special remover. In this case, all safety measures must be observed: latex gloves, safety glasses, respirator.

If all these methods do not help, then you can coat the walls with a special primer or purchase glue for vinyl wallpaper. But get best result you can by removing all the paint.

Almost any type interior decoration requires preliminary work, and wallpapering is no exception. Unfortunately, preparing walls for wallpaper in our new buildings is a necessity. Of course, it is possible to conclude an agreement providing for the final or rough finishing of the apartment, but the price of living space with this option will increase significantly. Therefore, new apartment owners believe that First stage You can also decorate your apartment yourself.

The need to prepare walls. Causes

Among the many reasons that provoke the initial preparation of walls for wallpapering, there are four main ones:

These are reasons that indicate the need to prepare walls for wallpapering, but some homeowners ignore this step. The motivation of these people is quite simple, in their opinion, the wallpaper changes every few years. However, replacement requires low-budget materials that were applied without preliminary preparation. Wallpaper of proper quality, pasted on the walls in compliance with all the rules, can last at least ten years.

It is not enough for wall coverings to look decent navigate only for their appearance and high price, do not forget about preliminary works Preparing walls for wallpaper, the work procedure is as follows:

These are the main stages of preparing the walls of a new building for wallpapering, but the secondary housing market also faces its own difficulties. The sequence of actions and attention to even the most insignificant elements have a positive effect on the quality of the preparatory work, and, therefore, on the final result.

There are apartment owners who prefer to glue new wallpaper directly on top of the old ones. Of course, everyone has their own approach to applying coatings to walls, but this method is fraught with consequences. For example, if the first layer of wallpaper begins to peel off, then you will also have to dismantle the coverings that were glued most recently. Thus, possible savings in money and resources will plunge you into even greater expenses. In addition, applying new wallpaper to old ones can provoke the appearance of fungi and mold underneath, because ventilation of the walls will be significantly hampered. Do not forget that after drying, unevenness may appear on wallpaper pasted over old ones, because the wall was unprepared.

Removing old wallpaper from walls

In order to get rid of old wallpaper applied to the walls of the apartment, you can use the following means:

• wide and narrow spatulas, the edges of which should be sharpened;
• Steam Mop;
• a special needle roller (you will need it for perforation);
• vinegar essence;
• dishwashing detergents that can dissolve glue and fats;
• conditioner used for washing;
• warm water;
• spray.

Removing wallpaper near heating elements and window sills without using improvised means is almost impossible to remove. That's why masters resort to various tricks. For example, initially it is suggested to moisten the area of ​​wallpaper that caused difficulties with water using a roller or sprayer. Dissolved in water detergents or vinegar, you will speed up the process of eliminating old coatings and, as a result, decorate your home with new wallpaper faster.
