Removing decorative wall coverings is a very dusty business, so do not forget to cover all surfaces with plastic wrap to reduce dirt in the room (this applies to all methods). Next, take a 130-150 mm long scraper and run it along the wall, pressing lightly. Having chosen the correct angle of application, start working. With light movements at the correct angle, you can scrape the finish: first start with a small part of the surface, then move on to a larger one. After that, wipe the walls with a cloth soaked in water to remove all particles and dust from the remaining decorative plaster. Rinse the cloth in water more often to wash the surfaces better. If you do not have a scraper, you can use a hammer and spatula. To do this, first wet the surface with decorative finishing with plenty of hot water. This is done in order to soften the putty well and reduce dust. Do not forget to wet the entire surface of the walls with water throughout the work, then removing the plaster will be easier. After you have moistened the surface, you need to tap the wall with a hammer. Thanks to this, those parts of the plaster that are not tightly held will fall off by themselves. Well, the others will need “help”. For this, you will need a chisel and a hammer: the layers of putty are lifted, and they fall off the surface in pieces. You will also need a spatula, which can be used to clean up the remains of the finishing material. Please note that the decorative finishing material must be removed from the upper part of the vertical overlap. You can also remove decorative plaster from the walls using a grinding machine with abrasive discs. Using this tool, the plaster is erased, not knocked off. But do not forget, you still need to moisten the surface, otherwise you will drown in a “sea of dust”. Get ready to work, since you will have to spend a lot of effort on grinding the surface. Decorative plaster must be removed carefully, not forgetting about the seams. After everything is freed from plaster, go over the wall with a metal brush to completely remove it. This is one of the most effective methods if hot water does not help.

Unlike a grinder, this tool works faster. Please note that you need to work with a grinder carefully, using special attachments that do not damage the walls. When connecting it, point it at the wall, but do not overdo it so as not to damage the wall.

It softens the paint that is under the wallpaper, and then remove it and the liquid wallpaper with a spatula. In order not to mess around with removing the plaster (liquid wallpaper) for a long time, they can be masked. To do this, the surface layer must be sanded: smooth out the convex parts, and roughen the smooth ones. Now you can proceed to the second stage - leveling the walls with putty.

When the primer dries, you can cover the surface with gypsum putty. Try to apply it so that the walls are smooth. For this, you will need a wide spatula. After the work has been done, the putty needs to dry for about 24 hours. After 24 hours, use a spray bottle to moisten the walls. Then apply a second layer of putty to the walls again. And let it dry for the same time as before. After 24 hours, apply a thin layer of finishing putty to the surface. Try to make the coating smooth.

Then it will be easier to replace the drywall with a new one, rather than deal with removing the layer of plaster. True, it will be more expensive. This is where removing the decorative coating from the walls ends. The walls are ready for your new fantasies: you can paint them, stick wallpaper on them, or apply a new layer of plaster.
