When carrying out repair work, many have questions - is it necessary to remove the old plaster? And if so, how to remove plaster from the wall quickly? To answer these questions, you need to know when plaster removal is required, what tools to use for this work are necessary and, of course, knowledge of some methods of such work will not interfere. Let's figure it out.
Analyzing old plaster
There are two ways to remove old, unusable plaster: partial and full-scale. In the first case, we are talking about local cleaning, when the main area of the layer is kept well, and only in some areas serious damage and shedding are noticeable. In the second, it is necessary to resort to larger-scale works and remove the entire layer. Before removing the plaster from the wall, it is very important to decide which case is typical in your situation.
The easiest way - to check which areas need local repair, is as follows: you need to pick up a trowel or a small hammer and use its handle to walk over the entire surface. In those places where a dull sound will be noticed or the plaster itself will disappear, accordingly it is necessary to clean and re-plaster. Also, problem areas are checked by detecting foci of fungus development or moisture seepage.
It is even easier to determine the need for full-scale dismantling work. If the 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 operation of cleaning the wall surface from the old plaster.
What tool should you use to remove the old layer?
Arm yourself with an appropriate set of tools before removing old plaster from the walls. In fact, its quantity and name will directly depend on the degree of wear. But in order to cover the entire section related to dismantling the old layer, we will list the most popular ones.
To withdraw, we may need:
- Safety glasses and respirator;
- Gloves - rubber or canvas;
- Ax / hammer / small sledgehammer;
- Chisel - it is best to take with a long handle;
- Scraper / spatula;
- Metal brush;
- Machine for removing old plaster;
Again, this list may not be typical for your case.
How is plaster removed?
In this section, we will look at how to remove old plaster from walls when it comes to complex dismantling.
First you need to moisten the entire surface with water. It is advisable to use warm, heated liquid to speed up the process itself. Water is needed not only to soften the old layer, but also to remove dust during work. If, during the dismantling process, some areas begin to dry out, you can safely re-treat them with liquid. You should not worry about the condition of the main surface - you will definitely not harm it, but abundant wetting of the plaster layer itself will significantly simplify the work. More options for how to clean the surface.
Removing old plaster
Let's now figure out how to remove plaster from the walls, going deeper into the process itself. Dismantling begins with tapping the surface: from bottom to top. To do this, you can use the handle of a trowel or hammer. Problematic pieces will immediately fall off the wall. To increase the scale of shedding, pry the fallen off area with a spatula. This will allow you to remove whole layers of plaster. If this does not work out, you will have to pick up heavier equipment, for example, a puncher. If this does not help to resolve the issue and the plaster stubbornly does not want to fall off, a grinder with special nozzles is used. Whole sectors are cut out with it over the entire surface, after which they are cleaned.
There is another way how to remove old plaster from the walls, but in this case, you need specialized electrical equipment. It's about grinding. But here it is not necessary to talk about withdrawal as such. After all, when sanding it is simply erased. The whole process is based on the use of a special machine with abrasive discs. This work is very dusty, therefore, as it is done, it is necessary to constantly wet the surface to be treated.
The final stage of processing is cleaning the wall with metal brushes. This completes the removal of plaster from the walls, and the process moves on to preparing the surface for further finishing.
