What fixtures may be needed?
Whether it’s vinyl or paper wallpaper, you won’t take them with your bare hands. Therefore, care must be taken to ensure that the following tools are at hand:

Paper Wallpaper Removal
Paper wallpapers come in several forms: single-layer, two-layer (duplex), with a moisture-resistant front surface (washable). Let's find out how best to remove old wallpapers from each type of wall.
- Single layer paper wallpaper.
This is the simplest coating that can be easily removed with ordinary warm water. Old wallpapers are moistened with a wet rag and after 5-7 minutes they are removed in a downward direction.
- Two-layer paper wallpaper.
Duplex gets wet longer, so after moisturizing you need to wait 10 minutes. Also, when removed, they can delaminate, but if the walls are even and do not need to be repaired, the bottom layer can be left (new materials will be better glued to it). If the coating needs to be removed completely, then the moistening of the walls should be repeated again.
- Washable paper wallpaper.
Moisture-resistant surface does not allow water to pass through, therefore, in order for water to penetrate, the top layer must be destroyed. The easiest way to do this is with a special tool - a wallpaper tiger. However, if it was not at hand, you can simply gently scratch the washable layer with a knife, iron sponge or any other sharp tool. In addition, it is better to repeat wetting several times with an interval of 15 minutes, then the old paper wallpaper will be removed quickly and easily.
Removing vinyl wallpaper
Vinyl wallpapers in most cases consist of a paper base and a polymer layer (polyvinyl chloride). Thanks to this combination, they are easy to glue, they are durable and well protected from moisture.In addition, the topcoat may have various additional characteristics. There are vinyl wallpapers with silk thread, washable, foamed. Some of them are even adapted for cleaning with solvent or alcohol. That is why old vinyl wallpapers are not as easy to remove as paper ones. In most cases, a special roller with needles is indispensable. So what should you do?
- Walk wallpaper tiger over the entire surface of the walls.
- Moisten the first cloth with a rag or roller, after 5 minutes the second and after the same period of time the third.
- Pry off the upper part of the wallpaper strip with the spatula, which was moistened first, and then gently pull down.
- Re-moisten all remaining small pieces and proceed to the second sheet.
- After removing the 3rd canvas, return to the beginning of work and clean up the scraps with a spatula.
- Process the next three in the same way.
It is this method that allows you to remove old wallpaper from the walls very quickly and easily, on average, removing 3 canvases takes from 30 to 45 minutes.
Tip
You do not need to moisten a surface that is too large: until you reach it, it will dry completely.
Difficult cases
Very often difficulties arise when, instead of a special water-soluble glue, vinyl wallpaper was “planted” on PVA, bustilate or any other compound that is not afraid of the effects of water. In this case, they can be removed from the walls only using a grinding machine with a coarse-grained skin or a drill with a round brush head. However, it is advisable to use the tool only to remove traces of glue, as well as small pieces of wallpaper. The rest of the wall surface will have to be processed manually with a spatula.
Another very often question arises: how to remove old wallpaper from walls covered with drywall? In most cases, this is impossible, it remains only to glue a new coating on top. The fact is that the top cardboard layer is firmly connected to the paper and the use of the wet method or special means can simply damage it. If gypsum plasterboard was putty, then there are usually no difficulties. You can use water, a spatula, or specially designed products.
