Despite the fact that sticking wallpaper is a fairly simple procedure, some of the nuances still cause people questions. In particular, home masters are often interested in how to glue wallpaper on concrete? Next, we will take a detailed look at the features of this procedure and consider the technology of gluing.

Wallpapering on a concrete wall

General information

So, is it possible to glue wallpaper on concrete? Of course, if you comply with the technology, the paintings on the concrete surface will hold.

However, experts do not recommend this for a number of the following reasons:

  • Wall roughness - As a rule, concrete walls have irregularities that are removed by plaster and putty concrete surfaces. After pasting wallpaper, these flaws will be clearly visible, especially if the canvases are light in color.
  • Rough structure - Concrete particles are larger than those of putty. Therefore, through the thin wallpaper will be clearly visible relief and microroughness. Therefore, even the plaster is recommended to putty.
  • Concrete has a dark color.which can show through through the canvases. This is especially true for thin and light wallpaper.

If all these unpleasant moments did not change your decision, for example, if the walls are smooth, and the wallpaper will be used sufficiently dense, able to hide the shortcomings of the concrete surface, then you can begin to stick.

Technology of sticking wallpaper to concrete

Tool

To self-glue wallpaper on concrete walls, you need to prepare the following tool:

  • Paint roller and pan;
  • Paint brush;
  • Rubber roller;
  • Clean rag;
  • Stationery knife;
  • Roulette and pencil;
  • Building level.

Training

The first step is to prepare the concrete walls for wallpapering. This is a very important procedure, as the reliability of the gluing and durability of the repair depend on it.

It begins with cleaning the surface of the wall from dust and other contaminants that can impair adhesion between materials. Then the surface must be primed.

To do this, you can use wallpaper glue, strongly diluted with water, but it is best to use a special primer, for example, acrylic. It is odorless, has excellent performance properties, and the price for it is quite affordable.

Its application allows to solve two important tasks at once:

  • Improve glue adhesion to concrete;
  • Prevent the formation of microorganisms under the wallpaper.
Wall priming

The priming procedure is as follows:

  • First of all, the primer must be shaken well.
  • Then the liquid is poured into a flat container, in which it is convenient to dip the paint roller. It is best to use a special pallet for this. It can be purchased at the hardware store with a roller.
  • Then the roller should be moistened in a primer and pressed so that the composition is evenly distributed over the tool and does not spray when applied.
  • Further, the wall is uniformly treated with soil from top to bottom. The composition should go to a thin layer, without drips and accumulation of fluid in certain areas.
  • After that, you need to wait for the surface to dry out and apply the primer on the concrete walls with your own hands again. Repeated priming will allow to achieve the maximum effect from this procedure.

Tip! Before proceeding to the primer, it is necessary to carry out communication. To do this, you may need to perform diamond drilling holes in the concrete, for example, to install outlets. In addition, channels should be laid out for cable management, in some cases it may even be necessary to cut the reinforced concrete with diamond circles.

Cutting wallpaper

Preparation of materials

The next step is the preparation of materials. To do this, first of all, you need to measure the height of the walls, then cut the canvases into the desired size pieces. When cutting it is necessary to leave an allowance of about 10 cm for the matching of the pattern.

Then you need to dissolve the glue with water. Instructions describing this procedure are available on the package with the composition.

Sticking up

Sticking up обоев на бетонные стены выполняется также, как и на шпатлеванную поверхность:

  • At first, a marking is applied on the wall, on which the first sheet of wallpaper will be aligned. To do this, retreat from the corner to the width of the web and draw a vertical line with a building level or plumb line.
  • Then the wallpaper is smeared with glue. I must say that when using non-woven wallpaper, should be smeared the wall, not the canvas.
  • Next you need to attach to the wall of the canvas and align the drawn lines. Smooth the surface using a clean cloth, while you should get rid of all air bubbles. It is more convenient to do this procedure together, so that one person smooths the canvases from above and the other - from below.

  • Then put the second canvas against the first one. When this pattern is docked.
  • After gluing the second piece, the joint should be “walked” with a rubber roller with a certain effort.
  • Further in the same way other cloths are pasted.
  • After pasting, a curb or panel is stuck on the upper edge of the wallpaper, which allows you to give the finish a finished look.

Tip! Until the wallpaper dries out, the windows and doors should be closed in the room, because otherwise all work can go down the drain.

At this process of pasting wallpaper completed.

Conclusion

Gluing wallpaper onto concrete walls without a rough finish is not the best solution. However, in some cases, this repair option is quite allowed. The only thing you need to comply with the above technology, and especially for surface preparation.
