Many people, dreaming of their own house, often fantasize on various topics related to the arrangement of living quarters.

Someone dreams of making a bar counter, others strive to create an exquisite wooden interior in an apartment or house using lining and bamboo wallpaper.

Start of renovation in a new apartment, wiring and preparatory work

When purchasing a new home, each person always experiences a lot of positive emotions, but over time, people begin to think about how to turn this empty room without communications into a cozy family corner.

The main question that every owner asks himself is: “Where to start the repair?”.

Indeed, a huge number of cases “float” to the surface. In a new apartment, in the first place, as a rule, electrical wiring is done.

Installation electrical wiring on the walls

When planning the power supply system of your living space, you need to thoroughly study the features of all rooms and schematically outline where the electrical points (sockets and switches) will be located.

It is from this action that will depend on how the tracing will take place. electric cable and where the junction boxes will be located.

Draw a wiring diagram

Each owner, when making repairs in his apartment, must know a number of recommendations and rules for installation, which are regulated by the following publications: “Electrical Installation Rules” (PUE) and “Rules for the Safe Operation of Consumer Electrical Installations” (PBEEP).

These are quite voluminous works, which are a postulate for the implementation of various electrical work. When organizing electrical wiring in an apartment, it is not necessary to study them completely.

Connect conductors with terminals

The main thing is to comply with the general requirements and the recommendations below:

• when mounting on a wall, the electrical cable must run strictly along horizontal and vertical lines,
• junction boxes should be removed from the ceiling at a distance of 20 - 30 cm,
• when measuring and laying a section of an electrical line between a socket or switch and a junction box, it is always necessary to make a supply of conductors of 20–30 cm for convenient connection and installation of elements,
• all electrical components in the apartment should be 10-15 cm away from the corners in the room,
• electrical switches in the room must be installed at a distance of at least 90 cm from the floor,
• when mounting sockets on the wall of the room, it is necessary to climb the wall by 30 cm or more,
• in junction boxes, conductors are recommended to be joined using terminal connections.

Some of the above requirements can be visualized in the diagram below.

Do not forget that a well-organized wiring of electrical lines in your living space guarantees the safety of working with various electrical appliances. Many experts for the organization of electrical wiring recommend using cable brands VVG and VVGnG. The thickness of the conductors is selected according to the power consumption of the connected devices.

Preparing the surface of the walls before finishing

After you have made the electrical wiring in the room, you can begin to prepare the interior finishing work, which will be carried out on all planes of the apartment.

Before leveling and cladding the walls of a new apartment, you need to take care of the evenness of the flooring. Many building professionals recommend that this process be performed using self-leveling gypsum-based screeds or self-leveling screeds.

The use of such material makes it possible in a short period to create a flat floor on which you can install the finish coating.

Surface leveling

To date, there are two popular ways to level wall bases. This is the performance of work with the help of a plaster composition and the method of creating a plasterboard coating. Both methods are widely used in finishing work.

Leveling walls with plaster is a traditional way of creating even walls that has been used for many years.

On aligned walls, you can safely mount the finish

Before applying a special mortar to the walls to level the surface, you need to set guidelines and understand how curved the wall is. best helper to solve this problem will laser level or a rule.

After you have found certain irregularities, you should make appropriate marks on the floor and ceiling. It is on the created marks that beacons (landmarks) will be set to create a flat surface.

Having set the guidelines and decided on the layer of plaster coating (2-4 cm), it is necessary to install a special grid (using mortar or dowels), after which you can throw a leveling compound on it, evenly distributing it over the surface, based on marks (beacons).

Before applying a plaster coating to a concrete or brick wall, the base should be properly treated with a primer. This is necessary to improve the adhesive properties between the wall and the coating.

Plasterboard installation and wall finishing

Seams are sealed with putty

Repair of premises with the help of GKL is fast, convenient and inexpensive option creating a flat wall and an excellent springboard for work finishing.

GCR is mounted on a frame made of aluminum profile or wooden bars. This design is quite quickly assembled and allows you to create separate decorative elements in the apartment, which can even have a functional value (shelves, niches, built-in wardrobes).

Drywall is attached to the frame with self-tapping screws, which, like the entire surface of the material, are later covered with a thin layer of putty, which is a good basis for any finishing material, and finishing the walls on such a basis will not cause great difficulties.

Finishing wall covering

By leveling the walls and preparing the coating for applying the finishing material and various decorative elements, you will take a big step, bringing the repair to its logical conclusion. It is worth choosing one or more types of products with which you will decorate the walls, creating an interior in the room that you will like.

Puttyed drywall and a plastered wall are ideal for finishing with the most popular material - wallpaper.

To date, there are many varieties of this product:

Each of these options has its own advantages and disadvantages. IN last years people tend to use natural materials. These include wallpapers made from paper, bamboo and leather.

Bamboo wallpapers - go well with other decorative elements made using wooden products (lining, imitation of timber). This material is not easy to install (after applying glue, it cannot be bent), but its performance will please any owner.

In addition to wallpaper, wall painting is often used as a finish. Paint is a versatile material that goes well with any decor elements (wallpaper, natural stone, ceramic tiles).

When choosing different finishing materials for one room, you need to imagine how they will fit together.

Wall decoration in a new building
Knowing how to decorate the walls in a new building will save a lot on costs and create a pleasant atmosphere in the room.

For finishing walls, non-woven wallpaper is often used now. This type of finishing material is quite versatile. It is easy to install and operate, waterproof, durable and able to hide some small defects on the wall. The choice of non-woven wallpaper can be made for any room.

Using non-woven wallpaper for walls

However, despite the simple requirements for wall covering, on which non-woven wallpaper will be glued, it is still worth preparing it. Today we would like to tell you how to properly work with the walls before wallpapering.

Preparing the walls

Wallpapering is not the most difficult task, especially if it is non-woven wallpaper, but it definitely requires a lot of patience. One of the most important stages of work is the preparation for gluing. The mistakes made at this stage will certainly lead to a worse result in the future, therefore it is necessary to withstand the technology, to do everything right. Almost anyone can cope with this task, it will be enough to gather strength and show some perseverance.

The main thing is not to overdo it with dismantling work and stop in time

We shoot wallpaper

First of all, we need to dismantle the old wallpaper, for this we need a sharp spatula and a large amount of water. It is better to choose a small but sharp spatula so that it easily cuts deep into the wallpaper material. A large spatula will come in handy for the following plastering work.

• If there is old paper wallpaper on the surface of the walls, then it will be difficult to remove them, use a large amount of water. Before dismantling, apply water and let it soak into the wallpaper, and then remove the old wallpaper.
• If wallpaper on a non-woven base was previously pasted, then, most likely, they will easily leave in whole canvases. However, in order to pour water behind the wallpaper, it is necessary to damage them, since they themselves are waterproof.

To create a smooth and straight wall, after the wallpaper has been removed, we need plaster. It is with its help that we will achieve a flat and smooth surface. Most often, wallpaper from the walls is torn off along with parts of the plaster, since they were glued tightly.

Not the worst option for dismantling old canvases

Therefore, before gluing new non-woven wallpaper, or non-woven fabrics, we need to create a smooth surface of the walls. To do this, we use plaster, you can choose the well-known German Rotband, you can use other options.

Plastering

The preparation of the walls begins with the very basics, with a thorough plastering of the surface. The first layer is applied base, up to a centimeter thick, two. The consistency of the plaster should be such that it can get into all the recesses of the wall. Irregularities up to a centimeter high are buried in the solution, and the wall becomes smooth.

Before the next layer of putty, called the “finish”, it is necessary to prime the entire surface of the walls. This is done to strengthen the inner layer of plaster. For primer, use special compound which can be easily found in the store.

The second finishing layer of plaster is applied after the primer dries, the thickness of this layer varies from 1-3mm. This thin layer of putty removes all minor wall defects. Usually, at this stage, builders recommend choosing Vetonit, but no matter what finishing putty you take, a second thin layer will help create a surface close to ideal.

Work on leveling the walls in the room

After the second layer of plaster has dried, the surface is sanded, the remaining minor defects are removed. Now the walls should be white and even, it will be easy to glue wallpaper on them on any basis, it remains only to solve the issue with the soil.

The plaster walls are behind, now we have to prime the walls again, but already before gluing wallpaper on non-woven base. You can prime with wallpaper glue diluted in a more liquid consistency, or use a special composition, which is also sold in concentrate.

This time we are producing a primer to reduce the absorbency of the wall surface. We need to ensure that the liquid from the glue is not immediately absorbed, and the wall does not remain dry.

Any person can cope with the task of priming

Now the walls are completely ready for gluing non-woven wallpaper, or non-woven fabrics. Recall that glue is not applied to such wallpapers, but only the wall is smeared.

Other options

A very bad option if you want to wallpaper a painted wall. Wallpaper on a smooth, slippery surface does not fit well, so before gluing, we will have to remove a layer of paint from the walls.

This is a very time-consuming matter, but if we want to make a full-fledged repair, we will have to sacrifice time. All basic preparation for working with wallpaper will consist precisely in removing paint from all walls in the room.

The paint on the walls is different

We can remove paint from the wall in several ways:

• The simplest and poor-quality option is to sand the surface of the walls, and in some places, use a knife to make serifs and notches. Then a primer is applied and wallpaper is glued, but they will not hold well everywhere.
• Another option is not the safest - the paint is removed from the walls with a spatula, for which it is heated with a building hair dryer. This must be done in a respirator and with well-established air circulation, since when heated, harmful substances can be released from the paint.
• The third option is very dusty and dirty - the paint is removed with a brush, or an iron brush worn on a puncher or grinder. When sanding the walls, a huge amount of dust is released, so the room must be isolated as much as possible: close all doors, windows and plug the cracks.
• The last option is the use of special solutions for washing off the paint and varnish substance. This method is also quite dangerous, so take care of personal protective equipment.

After removing the paint from the wall, before sticking non-woven wallpaper, the walls must be primed, because in the original version they absorb liquids very strongly. The primer concrete-contact perfectly copes with this task.

This time, a dusty method was chosen to remove paint from the walls.

If the walls were badly damaged when removing the paintwork, then we return to the plastering of the walls. In the presence of extremely large damage, it is even possible to plaster the walls on the lighthouses. However, this method involves the application of a large amount of plaster material.

Often there are such walls that you need to spend a huge amount of plaster to level them. In this case, it is permissible to consider leveling the geometry of the room using drywall. Irregularities and defects of the walls are simply sewn up with drywall sheets.

Use for plasterboard walls

On plasterboard walls, non-woven wallpaper is glued just fine, but it also needs to be primed, but in this case you will not need much primer material. Vinyl wallpapers on a non-woven base, they will perfectly lie on even, prepared plasterboard walls.

Proper preparation walls before you hang your wallpaper will avoid many problems in the future. Even if repairs are done by amateurs, many difficulties in the work can be avoided by carrying out elementary work to level the walls. In the future, you will only have to enjoy an excellent repair.

Preparing walls for wallpapering - step by step instructions

Often people try to decorate the house on their own, which as a result gives a pretty good result. Preparing the walls requires a careful approach to wallpapering. It will help in this case step-by-step instruction. It is important to take the procedure with all responsibility so that there are no problems in the future.

Preparing walls for wallpapering

1. Often, in multi-storey buildings, the walls have a far from ideal surface. Therefore, the preparation of walls for wallpapering should be done properly. In order for the result to please you in the end, you need to get rid of all the flaws and imperfections that interfere with high-quality repairs.

2. It is important to completely dismantle all the old coating. Resist the temptation to glue new wallpaper on a supposedly strong base of several layers. It is a mistake to believe that by doing so you will make your work easier. In any case, blisters could form under the old sheets in some places.

3. Such trifles lead to vain sticking of a new coating. In places of swelling, the sheets simply begin to lag behind the walls. Also, such trifles negatively affect the appearance of the room. Preparing the walls for wallpaper is an important component quality repair with your own hands. It is during dismantling that all the flaws that need to be eliminated are revealed.

4. Preparation of walls for wallpapering after dismantling begins with puttying. This is the step by step guide. The surface must be brought to an ideal state using a special solution. As a result, the canvases will lie much better and more evenly. It is also worth considering that light sheets will show through on a dark spotted wall.

5. Therefore, the preparation of walls for wallpaper implies a peculiar order of work. dark walls be sure to lighten, despite the fact that they can be quite even. After puttying, you need to proceed to the next step. This will require a primer. After processing the walls with it, the adhesion of the canvases to the surface will increase.

6. In addition to the fact that the wallpaper will stick better to the ground, the directional composition perfectly protects the walls from mold. A more professional primer is able to even out some bumps and holes. To do this, you need to resort to the help of a special thick primer. Therefore, in the general preparation of the walls, remove everything that may interfere.

Wall treatment before wallpapering

1. Regardless of the type of surface, it must be treated with putty and primer without fail. After dismantling and eliminating some problems and trifles, proceed further. In any case, the coating must be treated with putty. If the wall is even, apply a thin layer.

2. Using putty, you will give the wall a uniform tone that will not show through the canvases. It is also worth paying special attention to the type of putty. The material should adhere without difficulty in the future. Therefore, preparing the walls for wallpapering is so important.

3. Step-by-step instructions allow you to avoid common mistakes. Often, an acrylic mixture is used as a universal composition. Such putty is considered unpretentious and suitable for any purpose. Wallpaper on such a surface is quite good and lasts a long time. Also, in the future, you will not need to bother with serious repairs.

4. How to prepare the walls for wallpapering with putty is clear, now let's proceed to the next step. It is important to treat the surface with the help of soil with your own hands. As mentioned earlier, it provides better wall adhesion with sheets. Also, the primer protects the walls and wallpaper from the fungus.

5. As with putty, the primer should be selected on an acrylic basis. This composition has a lot of advantages, besides, it has no smell. The product dries quickly enough, the procedure takes 4-5 hours. Keep in mind that such a primer is not suitable for metal elements, corrosion appears.

6. If you decide to coat wooden surface elements, you should give preference to an alkyd primer. Acrylic mixture is also not bad, but alkyd is more suitable for natural material. Keep in mind that the alkyd base can dry up to 14-16 hours. Often, not many homeowners know how to properly prepare walls. Therefore, the process should be approached responsibly and study the market of materials.

Preparation of plasterboard walls for wallpapering

1. Do not mistakenly believe that preparing drywall walls for wallpapering makes the task much easier. Step by step instructions are also important in this matter.

2. Such panels must necessarily be covered with a composition of directed action against the formation of various fungi.

3. Drywall requires a kind of attention, so decorating the walls for wallpaper will be quite difficult. By using special device in the form of a sickle mesh and putty, it is necessary to close up all the joints and seams between the drywall panels.

4. This procedure must be done without fail so that during the subsequent wallpapering, the walls do not deform. Further drywall sheets primed with acrylic primer. Wait for the composition to dry and you can proceed to the final stage.

Preparing walls for liquid wallpaper

1. This issue has a number of its own characteristics. Wallpaper in liquid form is distributed over the wall along with all the dirt that is present on the surface. As a result, some irregularities and stains remain. The appearance of the room is deteriorating.

2. Preparing walls for liquid wallpaper requires special patience and accuracy. Therefore, in order not to encounter the above problems, you need to do everything possible with your own hands. Carefully walk around the perimeter and get rid of any dirt on the walls.

3. If you are faced with the fact that the walls are concrete or plastered and at the same time have fairly wide pores and minor irregularities, you need to eliminate this. Use gypsum putty, then walk with a primer in 2 layers.

4. Wait for drying, evaluate the environment, if there are any defects in the form of pores and irregularities. If everything is in order, treat the walls with a white base for liquid wallpaper. Such a move will help to avoid translucence of flaws that you did not see. After the base has dried, liquid wallpaper is applied.

Preparing walls for wallpapering requires patience and some skills. Step-by-step instructions will help you avoid common mistakes. Do not rush anywhere and do everything honestly. There is nothing difficult to repair. The main thing is to take into account all the little things, so as not to redo it later. Happy repair!

Finishing Finishing work internal surfaces premises is the most important stage in the whole process repair work. And a lot depends not only on what quality the wallpaper and glue will be chosen, how much skill is enough for the one who makes the repairs - if the preparatory work before pasting the walls with wallpaper is carried out with violations, then you can not expect a spectacular result. Preparing walls for wallpaper is a crucial moment, which involves taking into account some features.

The whole preparation process consists of several stages:

• cleaning the walls from the old coating (paint, whitewash, wallpaper);
• cleaning the surface from dirt / debris;
• getting rid of cracks and irregularities;
• ground work;
• choice of wallpaper and glue.

Wall cleaning

The complexity of the process will depend on what is in the "source" - a completely new apartment in a new building, walls with remnants of old wallpaper or oil paint.

Preparing walls in a new building

Going into new apartment, new owner square meters sees absolutely gray / rough walls, poorly installed sockets / switches - in this state of the surface, it is impossible to glue the wallpaper right away. To prepare the walls for wallpapering with your own hands, you will need:

1. Spray - in this way, absolutely all irregularities / cracks / are filled with liquid on the walls. The thickness of the spray on the walls should not be large - do not overdo it, the maximum allowable is to make a layer of 6 mm.
2. Apply a primer to the surface - its layer should also be 6 mm, but if the walls are too uneven, then several layers can be applied. The main purpose of using a primer is to level the surface.
3. Apply a finishing layer of plaster to the primed surface - its thickness is only 4 mm, it is a thin layer of finishing plaster that can be easily rubbed off.
4. Treat the prepared wall with fine sandpaper - make the surface as even as possible.

Only after completing all the above steps preparatory work before sticking wallpaper in a new building, it will be possible to start finishing work.

How to Remove Old Wallpaper Without Much Effort

If there are remnants of old wallpaper on the walls or they are completely covered with them, then you need to prepare a tool that will greatly simplify the preparation of walls for wallpapering. You will need:

• - spatula - it is optimal to have both narrow and wide available;
• - sprayer or roller / whitewash brush;
• - ordinary water;
• - aggressive means - vinegar, baking soda detergent for dishes.

Removing old wallpaper from the walls is easy - in some places it is enough to pull the corner with your hands and remove the canvases, but more often a spatula and water are required. Wallpaper on the walls should be dampened with water (roller, brush or spray), then removed with a spatula.

If vinyl / non-woven wallpaper was previously pasted, then the process becomes more complicated:

• we wet the wallpaper on the walls with water - this must be done quite abundantly;
• using a spatula, remove the top layer of wallpaper - vinyl / non-woven consist of several layers of paper;
• again we wet the walls with water and get rid of the remnants of the paper.

Sometimes on the cleaned walls are clearly recognizable rust spots- this is how rust appears from the metal frame of cast surfaces. There is only one way out - in the place where stains appear, a layer of plaster is completely removed, the surface is treated with an anti-corrosion agent, then plaster is applied again.

Getting rid of dirt and debris

After completing the first stage of preparing the walls for wallpapering, you need to thoroughly clean them of debris and dirt - use a vacuum cleaner or a broom with water. During the cleaning process, you can find cracks, falling off plaster - these flaws must be removed. If the crack is small, then it is simply covered with putty. If the crack is too wide, proceed as follows:

• clean the crack from dust / dirt, and, if necessary, expand it - all falling off plaster fragments must be removed;
• moisten the crack cavity with water;
• put putty on it and carefully smear it, trying to align the crack in one plane with the entire surface of the wall. Remember: when sealing cracks, the movements of the spatula with putty should be made in the vertical direction.

Getting rid of irregularities

Take a closer look at the prepared walls - do you see bumps, pits, "potholes"? It is imperative to get rid of them so that the wallpaper lies on the surface flawlessly. There are only two methods that can be used to level walls:

• plastering - the process requires skill and some experience, it can take several days;
• drywall installation - financial expenses will be needed, but the installation process is simple, subject to each person and takes a little time.

If drywall is being installed, then prepare the putty and reinforcing tape in advance - this will need to process the joints / seams of the drywall.

If you decide to plaster the walls yourself, watch this video review: a plastering master class is conducted by a specialist:

Whatever is chosen for leveling the walls, the next step is the primer, and you should not ignore it. When applying a primer solution on a cleaned and leveled surface, a thin film is formed - it serves as a factor in the strong adhesion of the wallpaper to the walls. Before priming, you need to clean the places where the putty was applied - this can be done with fine sandpaper in manual mode.

That's only after carrying out all the mentioned works, you can prepare directly for wallpapering. But first you need to choose them, and at the same time pick up the glue.

How to choose wallpaper and wallpaper glue?

We recommend reading:

1. Manufacturer- repairs are not done for a year (although there are such lovers of frequent changes), people will constantly be in the room, so the quality of wallpaper and glue should be at a high level. Only from well-known manufacturers can you get a guarantee of quality and be sure of safety for health.
2. purpose- for each type of wallpaper you need to select a special glue, and you can find out the markings on the packaging.
3. The possibility of changing the design of the room- if you are an adherent of frequent cardinal changes in styles, then it is better to paste wallpaper intended for subsequent painting. These are cullets - a relatively new finishing material, characterized by high quality, ease of application and long service life.

But even if the most expensive and high-quality wallpapers are bought, and the glue is provided by the manufacturer, there is no guarantee of a successful end result. Everything will depend only on how the walls were prepared for wallpaper - following all the above steps, or ignoring some of them.

Preparing the walls for wallpapering is a job that determines the quality and duration of the coating. This stage of work can, if desired, be performed by any person without special training. The main thing is patience and the desire to get a good result. And how to do it yourself, the article will help.

The main reasons why it is necessary to prepare the walls for wallpaper are:

Tip: Despite the fact that many consider it right to re-paste wallpaper after 3 - 5 years, due to a change in their appearance, this is not entirely true. Expensive materials, when properly glued, last at least ten years or until they get bored.

The main requirements for walls when applying wallpaper are:

Tip: If the walls are not processed before wallpapering, in unprepared uneven places, over time, any materials begin to tear, deteriorate or wear out. This requires a smooth and clean wall. This rule must be observed in concrete bases in the hallway or drywall walls in a small children's room.

• Most wallpaper sheets are unable to hide even very small defects.
• A mandatory requirement for the surface is dryness, good cleanliness and impregnation of the wall with a primer.

The abbreviated instruction for preparing the walls looks like this:

• The old coating is removed: wallpaper / paint.
• The walls are treated with a primer solution.
• plastered (see How to plaster walls with cement mortar.
• Are polished.
• Putty.
• Re-priming is in progress.

How to remove old wallpaper

Before preparing the walls for wallpapering, the old coating is removed.

To do this, you will need to purchase:

• Putty knife.
• Good quality roller.
• Liquid dispenser.
• Water and other aids that will ensure the quick removal of old canvases.
• A stepladder or a special construction bar, for convenient and quick work in hard-to-reach places.

Advice: Before starting work, precautions should be taken: turn off the voltage in the power supply of the working room, put on overalls.

Work order:

• In the areas where panels join, the quality of their adhesion to the wall is the lowest. It is from these places that you need to start tearing off the canvases, without the use of auxiliary means.
• Not removed parts of old wallpaper are abundantly wetted with a roller or sprayer with hot water.
• The surface is carefully cleaned with a spatula, everything that is easy to remove is removed from it.

Tip: To speed up the process of removing wallpaper, add vinegar or another adhesive solvent to the water. You can use special chemical compositions, which are designed to remove previously pasted wallpaper from the walls. But their price is quite high and such a purchase is not always justified.

Before preparing the wall for wallpapering, the old canvases must be completely removed.

How to remove old paint

Removing the paint yourself from the wall is quite simple.

With minimal effort, this can be done in several ways:

• The paint is pre-dried using a building hair dryer, then it is easily removed with an ordinary spatula. The method is quite effective, but harmful. This requires constant circulation of fresh air in the room. Due to the heating of the paint, the release of toxic substances hazardous to health begins, they cannot be breathed for a long time.
• Walls can be cleaned with a grinder or grinder.

Tip: This method is very dusty, it should not be used by people who suffer from asthma. During work, all adjacent doors to other rooms should be tightly closed, and the windows should be left open.

• The use of a flush mixture is the most effective option. The disadvantage of this method is when working with chemicals all safety precautions must be carefully observed and the manufacturer's instructions carefully followed.

How to process the walls before wallpapering, everyone decides for themselves. After their cleaning, the suitability of the surface for gluing the material is controlled. After this stage is over, you can start priming the surface.

How to prime walls

Wall priming is performed in order to:

• To prevent the peeling of small particles of plaster or concrete, penetrating deep into the thickness of the wall and fasten its surface layer.
• The primer composition (see Types of building primers and their scope) increases the drying period of subsequent layers of putty, depriving the wall of the ability to quickly absorb moisture, which improves the quality of the coating.

Tip: With the rapid drying of any mortar, nothing good will come of it, the minimum defect is the formation of cracks on the surface.

• Applying a primer removes dust. Apply the solution with a large brush or brush. The composition should be rubbed into the surface, as it were, until a white foam is obtained.

The next step, how to prepare a wall for wallpapering, should be carried out after the final drying of the walls.

Material application procedure:

• The primer solution is applied to the entire surface with a roller, as shown in the photo, evenly. Hard-to-reach places should be treated with a brush.
• With the rapid absorption of the composition into the wall, several more layers are applied additionally.
• After the primer dries, a rough leveling of the surface is performed.

How to repair potholes and cracks

Puttying the walls will hide cracks and potholes only superficially, and such defects can quickly appear again.

When filling cracks:

• They need to be increased to about one centimeter wide.
• Open these places with a primer.
• close up everything cement mortar or glue used for tiles, which is much better.

Cracks in plaster simply do not appear by themselves. This indicates that in this place the plaster began to lag behind the base of the wall. In this case, you will need to remove the falling plaster with a hammer.

Tip: When shedding old plaster in large pieces, you will need overhaul, which involves leveling the mortar walls a second time.

• After the areas have completely dried, they are primed with high quality and you can proceed to the next stage of surface preparation.

How to putty walls

How to prepare the walls for wallpapering? The next step is to apply at least a small layer of putty. It is necessary to reduce surface roughness and increase the bonding area. Putty just smooths out all the bumps.

Tip: Finishing putty should be applied only in thin layers, otherwise large ones will crack when dry.

All irregularities are eliminated in several passes, sometimes up to five times, until the wall becomes even. After the solution dries, all defects are removed from the walls with an abrasive mesh: tubercles and sagging. Small protruding sagging after puttying can be removed with a spatula.

How to make the final primer

At the last stage of work, which involves preparing concrete walls for wallpaper, their primer is again applied.

Tip: When preparing walls for wallpapering, after each step, the surface should be primed.

What and how to do before wallpapering, how to process the walls to improve the quality, the video will tell in detail.

Wallpaper is the most popular type of finishing materials. A huge variety of colors and patterns, a wide range of prices make the described material the most in demand in the construction market.
But you need to know how to properly prepare the walls for wallpapering, so that the most expensive wallpaper looks beautiful on the walls if it is properly executed for pasting.
Let's say right away that preparing the surface for wallpapering is not difficult, but it requires certain knowledge, skills and special tools. A beginner can easily cope with such a task if he carefully reads the proposed article.

Where to start repair

Any work begins with the preparation process. You need to purchase the material itself and related products, tools and fixtures.

About we have repeatedly told on the pages of our site.

Of the tools you will need:

• a mandrel for fixing an abrasive or a grinding block;
• abrasive material;
• sanding sponges for processing hard-to-reach places.

Grinding mesh can be used as an abrasive material, but it is cheaper to use sandpaper. The quality of work will not suffer from this.
The use of a grinding mesh makes work more comfortable, since the mesh is not clogged with debris and dust during operation. But the right choice of paper gives very good results. In addition, it is much cheaper than the grid.

The abrasive material is marked on the reverse side. The numbers 80…200 characterize the coarse-grained structure of the abrasive, and the numbers 250…2500 indicate the fine-grained structure of the emery material.

Sanding sponges are available with cut corners for easy processing of hard-to-reach places.

Of the devices you will need:

• ladder or sturdy table;
• spotlight or lighting device;
• spatulas;
• rule or level.

Always remember safety

Any work should bring joy and not have a harmful effect on human health. Preparing walls for wallpapering is a messy, dusty process.
You can not do without goggles, a respirator or a gauze bandage, a headgear.

Removing the old coating

Many are sure that gluing wallpaper is quite simple and everyone can handle it. This is really not a difficult, but rather labor-intensive process. Special efforts are required to prepare the walls for wallpapering, because this is the basis on which the further result depends. Everyone wants to have a finish that does not lose its appearance for many years, and for this it is very important to carefully prepare the walls.

Remember how our parents and grandmothers glued wallpaper? Basically, the walls were decorated without prior preparation, and after a few years the wallpaper lagged behind at the seams. They reduced the roughness of the surface of the plaster with the help of newspapers, which were so terribly translucent if the wallpaper was thin and light.

To date, it is recommended to carefully prepare the walls before pasting the wallpaper. after all, it depends on this stage how long the decorated surface will last. In this article, we will try to consider how to prepare the walls for wallpapering with your own hands, and also tell you what it is for.

Why is quality wall preparation so important?

There are many reasons why it is so important to prepare the walls for wallpapering, but we have highlighted the main and most significant ones.

Previously, wallpaper was glued with an overlap, not because of lightness, but so that one strip would hold the other and not peel off. Now all the wallpaper is glued end-to-end.

There are many other reasons, but even these are enough to make sure that the walls are properly prepared for wallpapering. Indeed, in most cases, the wallpaper is re-glued after a few years due to the neglect of the opportunity to thoroughly clean, level and process the walls before gluing.

How to prepare walls for wallpapering

To make it easier for you to navigate and understand how to prepare the walls for wallpapering, we have grouped all the steps into instructions. You just have to follow the steps detailed in it.

Wall cleaning

First of all, the surface must be rid of any traces. old finish. Wallpaper must be moistened with water and scratched from the walls with a spatula. To quickly remove the paint, you can heat it with a building hair dryer. You can read more about how to remove old wallpaper from walls or how to remove paint in the relevant articles. After removing the finish, the walls must be cleaned of traces of dust and dirt.

Primer

Let's say right away: the primer of the walls is required! Although many try to skip this stage, but in vain. Priming is dictated by three reasons:

Firstly, a high-quality primer penetrates deep into the wall, preventing concrete and plaster particles from peeling off. Strengthening primer is especially indicated for use on loose substrates.

Secondly, the primer prevents the absorption of moisture, which is especially important when applying wallpaper glue - it simply absorbs less and dries more slowly. Well, a layer of finishing putty applied to a primed wall dries in a timely manner and does not crack.

Thirdly, the primer removes dust from the surface, and dust, as you know, prevents something from sticking.

You can prime the wall with a roller or a large brush. Well, before further finishing, it is necessary to allow the primer to dry.

Sealing of cracks and potholes

As already mentioned, the wallpaper will not hide surface defects, so all scratches, pits and other irregularities are leveled with putty. If you have a plastered surface and cracks appear on it, this means that the plaster is falling off in those places. It must be beaten off from the wall and the pothole must be plastered over with a new one. If there is a difference of more than 5 mm on the wall, then this part should be leveled with plaster. The rest of the surface is leveled with finishing putty.

If you apply plaster or putty on an unprimed surface, then it is likely that the composition will simply crumble.

Application of finishing putty

You will have to apply at least a thin layer of putty, especially when it comes to old concrete walls. On a rough surface, the wallpaper simply will not stick, and after six months it will begin to peel off at the seams.

For perfect alignment, one approach is not always enough. Professionals often level walls in two, three, or even four stages. Having covered the irregularities for the first time, it is necessary to wait for the putty to dry completely in order to proceed with the application of the next leveling layer. After drying, the puttied surface must be sanded with a fine-grained sandpaper. Grinding is needed in order to make the surface smooth, without roughness.

Another coat of primer

And the final step in preparing the walls for wallpaper is the application of a primer. It is the primer layer that will prevent the appearance of fungus and mold, increase the adhesion of the wallpaper to the walls. It is applied with a roller or brush. If the walls do not absorb the primer well, it must be reapplied. The second layer is applied only after the first has completely dried. After this stage, the walls are ready for wallpapering.

I would like to note that the primer is a mandatory step between any layers of plaster, putty and wallpaper. For quality preparation, always choose a good primer, better than deep penetration.

As you can see, the process, although painstaking, time-consuming, but not complicated. The main thing is to know the technology, and then your finish will delight with its original appearance for many years. We hope this article was useful to you, good luck!
