The question of how to remove non-woven wallpaper is especially acute, because this type of finishing often presents difficulties in such a matter.

Tools that will be useful when removing non-woven wallpaper
It may seem to many that it is necessary to free the wallsfrom old non-woven wallpaper is not at all necessary, but this is not entirely true. The whole point is that if air has accumulated under the old layer or there are peeling areas, then the elements pasted on top will quickly peel off and fall off along with the old ones. In addition, the joints of the old wallpaper will still be clearly visible on the new ones. Another problem that often occurs when gluing new strips over old ones is the appearance of stains. Stains and streaks are a consequence of the paint from the old layer bleeding onto the new one.

Technology of removal of non-woven wallpaper
Tools for removing old wallpaper.Considering that the top layer of non-woven wallpaper is waterproof, first of all, you need to make tiger scratches over the entire area of the walls. This will allow you to achieve complete wetting of even the bottom layer when wetting. The more scratches there are, the faster the glue will dissolve and, accordingly, the faster the work of removing the stripes of old wallpaper will go. As a rule, non-woven wallpaper has a fairly dense top layer, so they come off in whole strips after wetting. Wet non-woven wallpaper with hot water with a small addition of dishwashing liquid. After wetting, you need to wait at least 30 minutes until the water gets into the scratches made by the wallpaper tiger. Now you need to carefully pry the peeling edges with a spatula and start removing the wallpaper. In most cases, the stripes will come off well and in large pieces, but this is not always the case. If the wallpaper comes off unevenly, you need to use a small spatula, having previously additionally wet the surface with water. If the strips were glued directly to the drywall, it is best to use a steam generator to pre-steam the surface. This will ensure that the glue that secures the wallpaper to the wall is well saturated with water. After steaming, the strips can be removed with a spatula or a metal brush, but this will require some effort. If there is no steam generator in the house, it can be replaced with an iron and cotton cloth. To steam, you need to wet the cloth well, attach it to the wall to be cleaned and iron it with a heated iron. This is a very effective method when you need to remove non-woven wallpaper, since under the influence of high temperature, not only the top layer of wallpaper falls off, but also the bottom, which allows you to quickly cope with the task of removing the entire decorative layer in the room. If there are areas on the drywall where the wallpaper holds very well, you can use a paper knife. In some cases, when removing non-woven wallpaper, only the top layer is removed, while the bottom layer remains on the wall. In this case, you should not remove the remaining white canvas, since this layer is an excellent basis for a new decorative layer, as well as painting, if such is planned. However, both a steam generator and an iron are extremely inconvenient to use in a room with high ceilings, where it is necessary to remove wallpaper from the upper part of the walls, because you need to use a stepladder, so additional tools can greatly interfere. When removing wallpaper in this area, it is best to simply thoroughly treat the wall using a wallpaper tiger, and then go over it several times with a roller, dipping it in hot water. The interval between wetting should be at least 30 minutes. After 3 procedures, the glue will soak well enough, and the stripes can be removed using a spatula.
