The easiest way to check which areas need local repairs is as follows: you need to pick up a trowel or a small hammer and walk over the entire surface with its handle. In those places where a dull sound will be noticed or the plaster itself will disappear, it is accordingly necessary to carry out a stripping and re-plastering. Also, problem areas are checked by detecting pockets of fungus development or moisture seepage.

It is even easier to determine the need for full-scale dismantling works. If old layer has already served its purpose, it will fall off along with the wallpaper. In this case, you will need to pick up the tool and proceed with the stripping operation. wall surface from old plaster.

So you can remove the plaster in whole layers. If this does not work out, you will have to pick up heavier equipment, for example, a puncher. If this does not help to solve the issue and the plaster stubbornly does not want to fall off, a grinder with special nozzles is used. Entire sectors are cut out with it over the entire surface, after which they are cleaned.

There is another way to remove old plaster from walls, but in this case you need specialized electrical equipment. It's about polishing. But there is no need to talk about withdrawal as such. After all, when grinding, it simply erases. The whole process is based on the use of a special machine with abrasive discs. This work is very dusty, therefore, as it is performed, it is necessary to constantly moisten the surface to be treated.

The final stage of processing is the cleaning of the wall with metal brushes. This completes the removal of plaster from the walls, and the process proceeds to preparing the surface for further finishing.

2. After cleaning the walls, you can apply a wax-based furniture polish with an antistatic effect. To update the gloss, polish the surface of the walls with a soft cloth from time to time.
3. To increase the service life and to enhance the brilliance of the wall, if necessary, it is necessary to cover with a layer of wax and polish to remove minor defects that have arisen during operation. This is especially true for aprons in the kitchen, plastered in the Venetian style.
4. In damp areas such as bathrooms or toilets, maintain good ventilation so that drops of condensate do not accumulate on the wall.

4. Next, select the desired plaster mortar. If the base is under drywall or gypsum mixture, then the defects are leveled with gypsum-based putty. If necessary, after drying, the putty is rubbed to perfect smoothness.
5. In order to repair the Venetian layer, you will need decorative material the same brand as on the wall. If it is not possible to install the manufacturer, then you will have to buy a white acrylic plaster. It must be tinted in the same color as the main finish on the wall.
6. The mixture is applied with a soft spatula to the area to be corrected. If the restoration area is large, then they try to repeat the pattern on the wall. Usually this is not difficult. because the Venetian is placed in multidirectional movements without a specific direction.

How to remove a Venetian from the walls

If Venetian plaster cannot be repaired, or you need to update the design of the room, you will have to completely remove decorative coating and replace with a new one. There are several ways to remove wall decoration.

Manually. Before starting to remove the old "Venetian" it is necessary to tap the entire wall with a hammer. The decorative coating will crumble in places where it has moved away from the base. Then the remaining pieces are scraped off with a scraper.

To facilitate the removal of plaster, it is moistened with water from a spray bottle or a wet rag. Gypsum putty under the decorative layer absorbs moisture well and loses strength after a while.

Areas that cannot be removed with a scraper will have to be beaten off with a chisel. At the same time, the leveling layer is also removed, because the “Venetian” with a thickness of 2-3 mm cannot be removed without damaging the base.

Important! It is necessary to perform all actions in personal protective equipment: bandage, gloves, goggles.

Removal with a perforator. Manual removal of old plaster is hard and long work, which will be facilitated by a perforator. It is used in the “hit” mode by installing a wide flat chiseling nozzle. The tool is held at an angle as close to the wall as possible so that the main force is along the surface.

Bulgarian use. To remove plaster from the walls, you can use the "grinder" (angle grinder). Via cutting wheel for stone (with a diamond edge), make vertical and horizontal cuts on the surface. The closer the notches are to each other, the easier it is to beat off the plaster between them.

In a brick wall, it is imperative to clean the seams with a chisel from the remnants of the plaster.

Removal machine. This is the fastest and best way to remove old finishes, be it Venetian plaster, paint or tile adhesive. The machine is equipped with a rotating milling head with movable toothed rollers. Around the cutter there is a brush casing. When removing the plaster, dust does not fly apart, but is removed from the surface by an industrial vacuum cleaner connected to the machine.

Such a tool is not cheap. For example, the German peeling machine "Eibenstock EPF 1503" will cost 40 - 45 thousand rubles.

Decorative plaster, a variety of which is also "liquid wallpaper", is considered one of the best and most fashionable finishing materials for the wall surface. It is easy to apply, and the effect is excellent.

Methods for scraping a decorative coating from the surface layer

We start with the first stage - scraping. There are several ways to do this job. They differ from each other different tools with which to perform it. Which ones you will use, choose yourself.

Removing decorative wall covering is a very dusty business, so be sure to cover all surfaces plastic wrap so that there is less dirt in the room (this applies to all methods). Next, take a cycle 130-150 mm long and run it along the wall, pressing lightly. By choosing correct angle applications, get to work. With light movements at the right inclination, you can scrape the finish: first start with a small part of the surface, then move on to a large 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 frequently in water to better clean the surfaces.

If you don't have a scraper, you can use a hammer and spatula. To do this, first the surface with a decorative finish must be moistened large quantity 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 the removal of the plaster will be easier. After you have moistened the surface, you need to knock on the wall with a hammer. Thanks to this, those parts of the plaster that do not hold tightly will fall off on their own. Well, others will need to be "helped". To do this, you need a chisel and a hammer: the putty layers are peeled off, and they fall off the surface in pieces. You will also need a spatula with which you can clean up the remnants of the finishing material. Please note that you need to remove the decorating finishing material from the top of the vertical ceiling.

It is also possible using grinder with abrasive discs. Using this tool, the plaster is washed off, not knocked down. But do not forget, you still have to moisten the surface, otherwise you will drown in the "sea of ​​dust". Tune in to work, as you will have to spend a lot of effort on grinding the surface. Decorative plaster must be removed carefully, do not forget about the seams. After everyone has freed from the plaster, walk along the wall with a metal brush to completely remove it. This is one of the most effective methods if hot water doesn't help.

Plaster removal may be required different occasions. This may be natural destruction from time to time, poor-quality installation, any negative physical or chemical impact, etc. The reason is not important, the main thing is that local repair impossible.

And how to remove plaster from the walls if it is made recently and from good concrete? Too strong and thick coating is sometimes difficult to remove even with a perforator. In this case, the Bulgarian will help us. We cut the surface with it to the depth of the finish, with squares of about 50x50 cm. Then it will become much easier to remove.

Preparing walls for finishing involves cleaning old coatings to the ground, in this article we will talk how to remove old plaster from walls. The solution to this issue requires a rational approach, since if the layer was applied in violation of technology or from low-quality materials, then it can simply crumble from touch, which would be nice and, on the contrary, hold on very tightly. Consider the worst case, and mentally prepare to do serious work.

Mechanical removal method

If you can use a power tool, it will greatly facilitate the cleaning of the walls from old plaster. As a rule, a perforator with a variety of nozzles is used in the work. The procedure is very noisy, dirty and dusty. It can be performed strictly during the allotted hours, for noisy work.

Manual removal method

Preparing to remove plaster from the walls

Before starting work, the surface must be checked for strength. To do this, you need to conduct a small test, using a conventional spatula. With the handle of the instrument, we tap the surface every 40-45 cm, carefully listening to the sound. If the blows are sonorous, approximately the same - as if you were applying them to concrete, then the adhesion of the plaster to the base is good, and this is not lucky. But if the sounds are deaf, using a special tool, in this place you can easily bring down a whole layer that does not firmly adhere to the plaster. If the surface of the plaster is heavily cracked, wide cracks are an indirect sign for recognizing the plaster as fragile. If at least one of the signs listed above is found on your wall, you can safely proceed to remove the old plaster from the wall.

Some builders remove only poorly adhering sections of plaster, in this case there is one rule: you always need to clean it up, a little more than it turns out and go beyond this fragment by 20 centimeters to the sides. This method can be used if you need to quickly complete the work.

Removing plaster without unnecessary labor

Not in all cases it is necessary to beat off the coating entirely. And not in all cases, when the plaster is in cracks, this means its delamination from the base. Each specific option, depending on the circumstances, is considered separately, although general rules should not be neglected.

If cracks are still found on your surface, they must be inspected for shedding edges, with obligatory tapping in this area. If deaf sounds are not heard when tapping, then the crack can simply be expanded with a suitable and convenient tool for this until a v-shaped section is obtained. Later on, at finishing works the crack is well primed and filled with the same plaster material, which is the main surface. After grouting is completed, provided that the work is carried out in compliance with the technology, there will be no trace of the crack.

For any plastering works it is necessary first of all to ensure good adhesion of the plaster to the base. Before any work finishing(paint or wallpaper) is carefully removed, and the surface must be primed.

With modern quality repair, in some cases even well-adhering plasters have to be removed in some cases. There can be many reasons for this, the main one is usually one - this is the large thickness of the old plaster layer, eating away usable space, which, with the current possibilities modern materials it is unreasonable to bear. In the process of removing plaster, the surface must be constantly moistened with water, this will prevent the formation of a large number dust.

A few basic options for how to remove plaster from walls

It all depends on the current situation, there are two ways to act, to use forceful measures (mechanized method) or to take cover to starve (manual method). The first option can save a lot of time, but it will require a lot of effort, the second is suitable for people who are not limited in time but at the same time have great patience.

Tools that will be needed in two cases to perform the work: a hammer, a special chisel, a spatula, a puncher with a variety of nozzles and a grinder.

Before starting work, you must protect yourself by wearing protective ammunition. To protect hands gloves, eye glasses, respiratory respirator.

Quick force method to remove unwanted plaster from the surface

Step 1: preparatory work

It is necessary to moisten the surface of the wall abundantly, it is better to wet it with a roller. The procedure should be carried out until the water stops being absorbed into the coating. In the event that for some reason it seems to you that the surface is not sufficiently moistened, repeat the procedure until you are convinced of this, it is difficult to overdo it - and there is no harm from it. You can check the quality of impregnation with an ordinary metal spatula by trying to immerse one of its corners as deep as possible into the coating. Only after you make sure that the layer of old plaster has become loose, and the spatula is immersed in it, you can proceed to the next step.

2 step: main work

Everything needs to start with testing, which was described above in this article. Having chosen the most poorly held area, we pick up a puncher with a chisel nozzle, put it in the strike position and try to chip off the first piece of plaster. First, notches are made, then they are hooked, and now whole fragments should already be separated from them. Depending on how well the plaster holds up, it will chip off in small pieces or whole layers.

3 step: cutting

Old housing stock, very often plastered with high cement content, they hold up so well that even a hammer drill can not always cope. The grinder, with a diamond wheel dressed on her, will help to significantly speed up the process. The plaster is divided into squares, horizontal and vertical lines are sawn, in the future the layers will be chipped off inapplicably along the applied cuts. Important point when working with a grinder, it is necessary to ensure that the surface of the wall is abundantly impregnated with water in order to reduce the amount of dust.

Gradual method of removing old plaster

Step 1: Getting Ready

As in the first case, the surface must be moistened, it must be moistened especially abundantly, and here's why: the work will be done manually, it will take much longer, so negative impact dust will be longer, the less it will be in the air the better.
