Before removing the plaster from the wall

Even if you yourself have plastered these walls, you do not know the exact state they are in now. To do this, you need to conduct a preliminary analysis of the coating to understand how to remove the old plaster from the walls:

1. Take a spatula, which you will then and process these walls.
2. Tap the handle of this tool every 30-40 centimeters.

Important! If you hear a loud bang, how would you hit the concrete, it means that the plaster is very strong and can be left. But if the sound is deaf, then it means that between the wall and this layer there is a small emptiness and the upper layer is no longer strong.

How else can you find out that the plaster is bad and will not last long?- Very simple! Over time, the top layer breaks from moisture and therefore cracks appear on the wall - this means that it can be safely cleaned.

Important! The quality of the plaster is evidenced by moist spots on the wall and the appearance of the fungus.

How to remove old plaster from the wall without unnecessary labor

There are cases when the coating should not be completely removed - its cracks do not always indicate that it is very weak. The most important criterion here is the final finish( paint or wallpaper), which you need to get rid of:

1. To remove the wallpaper, just wet them and remove with a spatula - so it will be easier to remove.
2. We remove the paint with the same tool, before tapping it with a hammer or with a suitable solvent.

If you have seen cracks in the finish, they can be locally reconstructed without laborious removal of the plaster completely:

1. Inspect carefully and check that their edges are not crumbling( tapping method).
2. Next, take a sharp object and expand the crack so that the letter "V" forms on its separation.
3. When you start reworking the wall, fill the mixture with two-thirds of the primed cracks, then top up with a primer to smooth the surface.
4. Wipe the marks from areas where there were cracks.
   

Sometimes there is a need to remove the old cover, because caring for it is meaningless - so we will spend more time, effort and money. In addition, there are modern quality materials that have a very good service life in their advantage.

Important! To how do I remove plaster from the wall without unnecessary labor?- The old layer must be saturated with moisture. Treat the entire surface with warm water - so it will be easier to remove it. In addition, this method will reduce the amount of dust when removing the trim.

Several options for removing old plaster from

walls There are two methods for removing old plaster: the use of force, the method of gradual removal of material:

1. The first method is much faster than the second, but it requires a lot of effort. In order to use it, you need to have a hammer with a chisel or an ax. You can do both, if the ax - take one that you do not mind, a spatula, a puncher and a Bulgarian.
2. In the second method, we need a grinding machine and its corresponding nozzles.

Important! To protect yourself from dust, use gloves, closed glasses and a respirator.

Power method:

1. Wall preparation. Rinse the walls well with water and wait until it is absorbed. If you see that the surface dries quickly, then the water is not enough - you need to moisten it. Check for saturation with moisture can be done by plunging a spatula into the wall to the maximum possible depth.
2. Initial processing. We take an ax and a hammer in order to tap the upper part of the wall and achieve the falling off of individual pieces. We make a hammer nicks and poddevayem them to remove parts of the plaster.

Important! With a chisel, you can knock down a lot more finishes.

1. Chiselling. In old houses, plaster often contains a lot of cement, so using tools such as an ax or chisel is meaningless, you can only spoil them. For this, a puncher will do - he will cope with this task. To do this, switch this tool into the chiselling mode and chop off pieces of plaster, placing the device at a slight angle to the wall.
2. Cutting. Since it is sometimes impossible to remove the old plaster from the walls even with a perforator( earlier in old mixtures for walls there was a lot of cement), then use the Bulgarian( set the stone disc on it).Do cuts along the length and width of the wall to get rectangles that will be easier to clean.

Important! Using the Bulgarian, water the walls with water so that there is no dust.

Method for gradual removal of plaster:

1. Impregnation. It is necessary to wet the walls very well so that they are as moist as possible. This will make your work much easier, because you have to work manually or using a special device.
2. Manual processing. If the plaster is very thin, then you can do with sandpaper with large grains( put it on the grater).Do movement in circles, and as often as possible, remove the paper from the worn plaster, dipping it in water.
3. Processing with a grinder. Use in the form of a nozzle an abrasive wheel and try not to wet it in water - better spray the walls with a manual spray.

These tips will help you the best way for you to make quality repairs. We wish you success!
