Why glued newspapers on the walls?

In Soviet times, newspapers solved several problems simultaneously due to a shortage of high-quality building and finishing materials:
- Replacing plaster. With their help leveled curved walls. Now there are more suitable and convenient materials for this.
- Reliable fixation. Another task of the newspapers was to keep the finish. Thin newsprint paper was well impregnated with glue and glued to the concrete walls easily and reliably, so the wallpaper held well.

- The old ones were paper, not vinyl, non-woven, washable.
- Wallpapers are firmly glued to the wall and never move away from it.
- The texture of the old coating is smooth, there are no voluminous, eye-catching patterns that can appear with ugly irregularities.

There are few advantages to the decision to glue wallpapers on top of old ones - saving time and budget, but there are much more disadvantages:
- The fastening of wallpaper to the wall is less reliable, the risk that the coating will recede increases several times.
- The appearance of the walls is worse.

- Penopolisterol - for reliable fixation of finishes it is better to choose a heater with a top cardboard layer.
- Foamed polyethylene, it is covered on both sides with a layer of paper, so it is easy to glue it to the wall and the wallpaper on it keeps well.
- Cork insulation is a natural material, it can also be used as a finish.
- Ready-made self-adhesive wallpaper for insulation of non-woven and aluminum foil.
All these materials provide not only thermal insulation, but also sound insulation, and also make the walls more even. You can glue the wallpaper on top of the insulation repeatedly; you do not need to remove it from the walls with each subsequent repair. But under the insulation itself the walls will still need to be prepared - to clean the old coating, to plaster and prime, only after that to stick the insulation.
You need to glue the material as usual wallpaper, carefully smoothing it to the sides, as well as from top to bottom.Bands need to fix butt. It is recommended to glue stitches with paper tape or masking tape. Drying time will take from one day to three days. Only then can it be stuck on top of the finish.
