Is it possible to glue wallpaper on the wallpaper

Each person can have a moment when he suddenly realizes that he is tired of what he sees around every day. But far from always this understanding entails a willingness to radically change the interior and global alteration of the apartment. Then a successful design decision comes to the rescue - replacing the usual wallpaper with photo wallpaper. And if during the first decoration of a new apartment, doubts about the need for rough preparation of the walls are not arises, then with subsequent cosmetic repairs the volume, cost and dustiness of the work cause justified panic. Also, there may be a need to wallpaper the entire wall, but only its section (as an option - a photographic panel). In these cases, the logical question arises: is it possible to glue photo wallpaper on old wallpapers? The answer to it can be positive only under stringent conditions.

Important! Despite the fact that it is planned to stick the new paintings on the old ones, the wall will still have to be prepared, and the preliminary work will depend on the materials of both coatings.

Conditions for gluing the second layer of wallpaper

If you plan not to remove the old finishing material from the wall, but to update it by gluing photo wallpaper, then First you need to make sure that the following conditions are met, which are mandatory for this type of repair works:

1. During the previous gluing, the surface was prepared, i.e. aligned with plaster and putty.
2. The first layer is firmly held on the wall (especially at the joints), there are no defects, tears on it.
3. Old wallpapers must be moisture resistant, i.e. when glue is applied to them, the coloring layer should not dissolve and leave traces.
4. If the existing coating is textured, then the relief depth should not exceed 0.2–0.3 mm. Even subtle elevation changes can distort the picture, especially when it comes to fashionable 3D photo murals.

If the wall covering satisfies all conditions, you can act. Well, if the old material does not fit in at least one of the points - alas, this idea will have to be abandoned and prepare the surface for sticking in accordance with all the rules.

Wallpaper selection

When choosing photo wallpaper for gluing on a wall with wallpaper, you should focus on the material of the existing coating.

• If on the surface there are light quality paper glued on canvas - this is ideal, the material of the photo wallpaper can be any. In this case, the adhesive applied in several stages permeates both the old material and the wall underneath, and it means that on such a surface a glued layer of photowall-paper of any density and invoices. Can be used paper based vinyl wallpaper or non-woven, paper, textile, non-woven.

• In the case where there is a reverse situation, and the new canvas is supposed to be glued to vinyl wallpaper, as well as dense and heavy non-woven, for the second layer it is better to choose a paper-based coating with a high density.

Advice! When choosing photo wallpaper, it’s worth considering that pastel shades of paper material are too soft, they may not be able to hide the previous finish, so it’s better to use brighter and more contrast Images.

How to stick photo wallpaper

The only difference between working with murals and gluing ordinary canvases is the preparatory stage. In addition to bringing to the ideal the working surface of the wall, it includes its exact marking to eliminate errors when joining the picture.

Preparatory work

To prepare the wall, you must perform the following steps:

1. Carefully glue (even reliable at first glance) the joints of old wallpapers.
2. Putty defects (most often the finishing mix is ​​enough).
3. Degrease “suspicious” spots.
4. Primed the wall.
5. After 24 hours, you can start marking and sticking a new finishing material.

Surface marking

Each set, as a rule, contains a description and a list of sizes of paintings with drawings, as well as recommendations regarding the gluing process.

1. Using a tape measure, the necessary height of the whole picture is measured and marked on the wall, in the place where it is planned to center the image.
2. Then measurements are made across the width of the canvas, and with the help of the level, clear boundaries are marked out for each part of the picture.

The choice of glue for photo wallpaper

The choice of wallpaper glue directly depends on the density of the coating materials. If paper webs are the first layer, then it is enough to follow the manufacturer's recommendations on the packaging. Usually these are the types of glue:

• Composition for light wallpaper used for paper paintings.
• Adhesive for heavy wallpaper material, suitable for coatings of textiles, vinyl, non-woven.

In the presence of a base layer of increased density (even if the bonded material will be on a paper substrate), it is recommended to choose "heavy" types of glue. When a special composition is used for photo wallpaper, it is usually included in the proposed kit.

Advice! In order to simplify the gluing and make the adhesion of new wallpapers to the old ones more reliable, it is recommended to add PVA glue to the prepared solution, approximately 10-15% of the total amount.

Bonding process

Qualitatively stick photo wallpaper on the wall brief instructions will help.

• The material can be glued starting from any fragment, while carefully following the markup.
• When working with photowall-paper, glue is applied both to the canvas and to the wall and is kept for several minutes (the exact time is in the manufacturer's instructions) without folding, so that the base is well saturated.
• It is important to ensure that there are no air bubbles, and to smooth the canvas from the center to the edges using rubber rollers or a spatula.
• After gluing all the fragments to the old wallpaper, the joints are checked, rolled up to full fixation, excess glue is removed with a sponge.

• After drying, a special finish coating can be applied to the surface to protect the image from fading.

In the room where the wallpapering is planned, there should not be the slightest air movement for at least a day, and the temperature should be maintained in the range of 15–20 degrees.
