Is it possible to glue wallpapers to wallpapers, and in what cases?
Here, it would seem, who can come up with the need to paste wallpapers on an identical cover, which for some time already exists on the walls of the room. But, imagine, there are cases when other options are less preferable or generally unacceptable. Do you want examples? You are welcome. First and foremost, design requirements. If you decide to use the combining method, and chose a method such as an insert, the best option is the wallpapering of the wallpaper on top of the others. Just the basis for the decorative fragments will be the first layering.
Another case - when the old wallpaper is so tight that it does not make any sense to rip them off, the costs of labor will not be justified. There are cases when in houses built at the beginning of the last century and transferred to a housing stock, the owners during repairs, deciding to peel the walls, found layers of cloths of different materials up to two centimeters thick. Well, and, finally, as an extreme case - the reluctance to fool with the cleaning of the walls. For example, using the correct composition of glue, you can save yourself in the future from such a need.
You can glue wallpapers to wallpapers, but there can be difficulties
Many people know about the pre-pasting of walls with newspapers, which was common relatively recently among amateur artists and some professionals. And, it would seem, that's why it's possible to glue wallpapers to wallpapers, however, there are some difficulties. First of all - the susceptibility of the finishing material to adhesion with the new layering. In other words, if the old wallpaper, which was decided to cover with new, vinyl, glue them to smear at all will not succeed. The same applies to metal, as well as fiberglass coatings.
Another trouble can happen if the old wall covering is paper and not of the highest quality. In this case, when applying the adhesive, the carrier layer of the wallpaper can become wet and begin to be collected by folds, or even to go as a bubble. Another problem that should always be feared is the penetration of ink from the old coating through a new layer. To prevent this from happening, when pasting walls without first cleaning, you should first try to apply a damp sponge to the old coating for a short period of time. If it appears to be in the slightest degree colored ink, before pasting the walls it will be necessary to apply directly to the old coating the sealant against the stains.
Technical secrets for pasting
walls As already mentioned above, there is a special composition that, when applied, the fabric prepared for wall finishing is glued tightly, and further layers are possible later. The composition of the mixture is completely accessible to everyone: one part of PVA is mixed with two or three parts of wallpaper glue. Few other proportions of the same components - 2: 1, respectively, are used to pre-smear the surface of the wall at the joints.
In the presence of two layers of wall decoration with wallpaper, a third glue is not recommended, but there may be exceptions if the carrier layers hold on tight and represent an absolutely smooth surface.
Another important point - when you are gluing the wallpaper on the wall, with the slightest skewing or the appearance of the fold, you can gently peel off and smooth more carefully. It is a mistake to assume that it is also possible to glue wallpapers to wallpapers, because any attempt to correct a mistake can lead to an even greater aggravation of the current situation. In other words, for gluing the walls, if you refuse to pre-clean them, you will have only one attempt, and you should use it with the utmost efficiency.
