One of the main stages of apartment renovation is wallpapering. This type of room decoration requires some knowledge, since the preparation of the walls takes an important place in this process. To get the desired result, it is necessary to properly prepare the surface for gluing. The features of this process will be discussed in our article.

Process features

The process of preparing the walls for wallpapering can never be ignored, because it is always important how well the canvas is glued. Do not think that all the flaws will be hidden under the new expensive wallpaper, so in no case miss the alignment stage.

The reasons for preparing the walls for wallpapering are numerous, but I would like to note the main ones:

  • A porous surface will not be able to hold the wallpaper for a long time.
  • An uneven base will directly affect the final result.
  • A smooth, prepared surface will provide good adhesion to the coating.

In the process of preparing surfaces, you will need many tools, such as a roller, a knife, brushes of different sizes, a primer, putty, glue, sandpaper.

An important stage in the work is the creation of a workspace. To protect the floor from various substances, it is recommended to cover the film. To avoid drafts, it is necessary to close the room and keep the temperature between eighteen and twenty degrees. It is important to make sure that there are no foreign objects on the walls, such as old nails or screws. It is important to know that you should not leave the old wallpaper and glue new ones on them, otherwise the old pattern may appear, and the swelling of the canvas may also appear.

Working with different surfaces

Before you start wallpapering the walls, you should determine what type of surface you will have to work with:

  • If the wall is done drywall, then, despite the fact that the surface in this case is quite smooth, it differs in porosity. It is required to perform additional smoothing of the plasterboard wall, while taking into account the numerous seams at the joints. It is recommended to use putty, but with minimal material consumption.
  • For processing concrete wall it will take more time. It uses primer, plaster, and in some cases putty. The primer mixture improves the adhesion of materials. The problem with the treatment of concrete surfaces is the dark color of the base, which is not very good if you are going to glue light-colored wallpapers. The use of putty will come to the rescue.

It is not recommended to glue paper wallpapers on concrete bases:

Brick surfaces do not differ in evenness, so their preparation will take much longer. There is a long work ahead, which includes the stages of leveling using plastering, applying a solution for a primer, puttying. Plastering mixes are sold ready-made in specialized stores. To obtain a high-quality solution when diluting a dry mixture with water, it is better to use a mixer. The use of plaster is not always necessary. If the wall is dry and without irregularities, then you should not spend money and time on this stage

As for the putty, it will help to properly fix the wallpaper. After the end of this stage of processing, the walls are sanded.

OSB boards are similar to the previous type of stem, so they should be handled in the same way. This also includes finishing the joints between the slabs. Preparation of walls from OSB and chipboard is carried out with a special type of putty. Renovation in a new building is not always done with high quality, so often the owners of housing in a new panel house face the same problems as residents of old buildings. It is common that the sides of the panel are not even enough. Experts recommend using several layers of plaster before proceeding with wallpapering

There is a variant of gluing wallpaper on plywood. In this case, the preparatory work will consist of a preliminary application of a primer layer.

Next, you should pay attention to the seams between the canvases. It is important to putty them, otherwise defects will be visible through the wallpaper.… It is best to glue non-woven wallpaper on this type of surface, since their density will hide possible small irregularities and roughness.

How do I clean the surface?

An important procedure before applying new wallpaper is to get rid of old coatings. This will require a number of cleaning tools that are easy to find at home improvement stores. Clearing the base for a new wallpaper is not so difficult if you follow some basic rules:

  • It should be remembered that near heating devices and near windows, wallpaper leaves quickly, and a lot of energy is not expended for this process. If this cannot be done the first time, the wall is soaked with water and then the remnants of the wallpaper are removed with a spatula.
  • If you have to remove old vinyl wallpaper, then it is important to remove the vinyl layer first, and only then the paper itself. Hot steam will help to remove non-woven wallpaper. This way, the old canvas will be cleaned up very quickly.

  • If the task is to get rid of old washable wallpaper, then this can only be done in layers. First, a thin layer is removed, then a paper one. Here, too, the use of a steam iron or steam cleaner will help.
  • Another problem in the cleaning phase is paint stripping. In this case, you can resort to several methods of removing the coating. You can try cleaning the base with your hands and using tools. A regular hammer or wire brush works well.

An alternative option would be to use chemicals, the list of which is extensive and available for sale. After this cleaning method it is imperative to wash the wall, preferably two or three times:

  • If whitewash remains on the wall, then it must be of high quality, also without cracks and chips. On this basis, the new wallpaper will hold up well. However, the whitewash is not always of good quality and may peel off. In this case, it should be cleaned in order to avoid further problems.
  • Next, you need to clean the wall to get rid of debris and dirt using a vacuum cleaner or a broom with water.
  • At the end of the cleaning of the base, it is proposed to evaluate how the surface is ready for pasting.

What needs to be pre-processed?

How long the new wallpaper will last depends on the correct processing of the walls before gluing. In this regard, it is necessary to process the base carefully so as not to miss important points, especially if you are going to do everything yourself:

  • It is already known that the surface must be leveled and properly cleaned. The cleaned bases are checked for dents, scratches. There should be no dirt on the substrate. Using a putty will help prepare the surface more thoroughly.
  • A fungus may appear on the wall, in order to avoid this, the base should be smeared with special antifungal compounds. It is important to know that it is necessary to prepare the base for puttying after applying the anti-fungus agent.

  • If you plan to cover with liquid wallpaper, then the processing technology is practically no different from surface preparation before gluing paper wallpaper. In this case, the base under the wallpaper must be smeared with a primer mixture. Usually the surface is covered with soil in two layers.
  • It is important to remember that if the walls are strewn with irregularities, then no processing and further putty will not save. Here drywall comes to the rescue.

The order of the work performed

The stages of preparing the walls have already been considered, however, now it is necessary to determine in more detail the sequence of preparatory work before pasting. Preparing the base for gluing is as important as processing it for painting.

Remove the switch

When preparing the walls, it is recommended to remove the housings of electrical outlets and switches. There are various types of power supply devices, in this regard, it is not always unambiguous to determine how to properly remove the switch. The network can be connected through circuit breakers. In this case, you will have to disable all protection.

There are two types of switches. They differ in the types of fastening. The switch can be fixed to the wall with screws. There is also a hidden-type switch, the box of which is located under the wall.

The modern switch has a smooth surface, the fastening is hidden. The first step is to remove the fastener keys. If you cannot do this manually, then you should use a screwdriver. After the switch fixation is removed, check the absence of voltage on the wires. Next, you need to disconnect the wires.

To avoid electric shock, all internal parts of outlets and electrical switches that are left without external protection must be pasted over with tape or other similar material.

Treatment

If, after removing the wallpaper, irregularities are found on the wall, plastering should be resorted to. Plaster mortar is easily made by hand using sand and cement. The mixture is slowly stirred and water is gradually added to it.

The plaster is applied in three layers. The first layer should be no thicker than three millimeters. The second layer is aimed at leveling the plane of the wall and cannot be more than six millimeters.

The finishing stage of plastering is a so-called coating, which must be done very thinly.

You cannot proceed to the next stage of processing until the plaster is completely dry. Do not rely on fast drying of the plaster mortar., as this can affect the quality of the material and its service life. The normal time for plaster to dry is about a day. After that, the wall is cleaned with special tools to level the surface and remove all defects.

Next comes the priming of the walls. In order for everything to go smoothly in the process of gluing wallpaper, you must use a primer. The importance of this stage is due to several reasons:

  • The primer helps to hold the surface together and prevents further deterioration and flaking of the trim parts.
  • The mixture of soil composition prevents the rapid absorption of moisture.
  • The primer helps to deal with dust.
  • The primer composition easily penetrates into any thickness. To apply the primer, a brush or roller is sufficient. The primer mixture, when applied to the surface, forms a protective film, in addition, it evens the plane, cleans the base from small debris.

Before gluing the wallpaper, the walls are primed for:

  • the formation of a smooth plane;
  • strength;
  • protection against fungus;
  • guarantees of sustainability.

Today there are several types of primers:

  • The most famous of them are acrylic. They can be used on any surface. They have a high drying rate and do not have a pungent odor.
  • The next type of soil solution is called alkyd. It is not suitable for all bases; more often it is used for treating wooden surfaces. This solution dries longer than acrylic.

  • Another equally common type of priming is the treatment of walls with a glyphthal mixture. This type is suitable for metal substrates.
  • Mineral primers are good for brick or concrete walls.
  • Deep penetration soil mixtures are used for additional strengthening of surfaces. This type of primer can penetrate into the surface from five to twenty millimeters. Often, these types of soil solutions include substances that protect the bases from fungal formations.

  • There are formulations with coloring pigments. Such primers are suitable for treating walls before gluing light-colored wallpapers.
  • Quite often, when renovating apartments, it becomes necessary to fasten various materials. In this case, a special type of primer called concrete contact comes to the rescue. Such a solution changes the surface of the base, which makes it possible for the materials to fix on the wall. This composition has many advantages: it serves for many years, has an insulating effect, and dries quickly.

Seams and cracks are sealed behind the primer. Deep cracks are usually enlarged, treated with soil and repaired with cement mortar. It is imperative to check whether the rest of the plaster is lagging behind the wall … It will most likely need to be removed with a hammer to avoid re-leveling with plaster in the future.

The next step will be putty. This process does not take long, it is quite simple. Small defects and unevenness of the wall can be easily eliminated with a putty and a spatula.

All the necessary materials and tools for this are sold in any hardware store and are inexpensive.

It is recommended to apply putty on plastered walls if the walls are not very crooked. Puttying is a mandatory step, as it can significantly reduce the level of roughness of the base. With the help of the puttying tool, all irregularities are eliminated in several passes. To achieve a perfectly flat wall, you will have to putty at least three times. It is important to note that the last layer (finishing) should be the thinnest.

It is worth paying additional attention to the need to sand the surface both before the start of the putty and after it dries. Sand the wall until it is perfectly smooth … An important point is the choice of a putty solution, which is made from different ingredients. Experts believe that the best option is an acrylic mixture.

The puttying process can include several stages, depending on the condition of the walls:

  • Initial coverage. This is a rougher finish that allows you to align all kinds of pits, chips, cracks. With this method, you can use a gray mass. Puttying is best done using beacons. They will help make the surface smoother. They can be made from different materials.
  • Finish coating. This is the layer that prepares the base for wallpapering.
  • The last stage of treatment is re-impregnation with a primer. In fact, the same is done as before filling. The only exception is the volume of the mixture consumed. It will take less of it, since the foundation is almost ready. Before you start gluing the wallpaper, you should definitely wait until the soil solution is completely dry.

Sticking

With strict adherence to all stages of preparation, gluing the wallpaper itself will not cause any problems. The main thing is to follow the instructions exactly, depending on the type of coating, to ensure the optimal indoor climate, to use the appropriate adhesives, etc.

Recommendations

We examined the main features of preparing walls for wallpapering. It remains only to summarize and give some useful recommendations to those who decided to start preparing the surface on their own.

Important tips:

  • In order for the wallpaper to last for many years, you should not ignore the instructions of the technological process, which includes putty and base primer.
  • The finish will never stick to the glossy paint, however, if you process the base with a special tool, it will become rough, which will allow the glue to stick well.
  • The joints between the wall and the skirting board are best cleaned and filled with a plaster solution, wait until it dries, then remove the remains of the dry mixture.
  • It is important to treat the seams on the drywall surface with putty, preferably painting them with oil paint.
  • To avoid seeing the traces of the nails with which the drywall sheets are attached, if possible, they should be deepened into the material.
Image
Image
  • If you skip the priming stage of the wall, then as a result, the finish will not be able to last long.
  • During the plastering process, those parts of the walls where the metal reinforcement is visible are carefully processed. This must be done in order to avoid the appearance of yellow spots on the wallpaper in the future.
  • After each stage of wall treatment, the surface must be thoroughly dried. It is better to do this naturally without the use of artificial air heating devices. If the wall is not well dried, this will lead to dampness, and subsequently to the appearance of fungus.
  • During the filling of the walls, the trowel tends to leave noticeable streaks. To reduce the roughness of the surface, two thin layers are applied horizontally, and the next layer should be done in the vertical direction. You can also do this diagonally. This will give the putty layer a smoother look.
Image
Image
  • When choosing a tool for puttying, its dimensions are taken into account. The most optimal would be a spatula with a width of thirty to forty centimeters.
  • When choosing a wallpaper glue, you should pay attention to its important characteristics. Firstly, the emphasis is immediately placed on a trusted manufacturer. Repairs are always planned to be done not for a year, so the quality of the glue should be at a high level. Secondly, be sure to make sure that the adhesive is suitable for the type of wallpaper you have chosen. There is a separate type of glue for each type of canvas.

Do not forget that no matter how high-quality the wallpaper is, there is no guarantee of a successful final result. It all depends only on how the walls were prepared for wallpaper.
