Any repair sooner or later becomes worthless and there is a need to refresh it or completely redo it. If pasting wallpapers does not take you too much effort in preparing the process itself, then with staining everything is much more complicated. The process of dismantling old paint from the walls is very difficult, but knowing some tricks, you can cope with this work faster and more efficiently.
Repair work to remove paint from the wall surface will depend on your ultimate goal. If you just want to repaint the wall, then a new layer of the coloring matter can be applied on top of what was previously. This option is possible if the wall is flat and the previous layer did not crack, bubble, and do not deform.
If there are any changes in the surface, then you need to clean the surface. This is especially important if, instead of painted walls, you want to stick wallpaper and radically change the mood of the room. In this case, it will be simply necessary to remove the old paint from the wall. This work is not easy and will require both knowledge and physical preparation.
It will be easier to remove the old layer if it is thick, painted several times, but if it is applied for the first time, and even on concrete, then there will be a long and painstaking work. In order for the process to move faster, you need to prepare all the necessary tools that will help you. It can be:
- Personal protective equipment: gloves, glasses, mask-respirator;
- Soldering iron or building hair dryer;
- Sharpened spatula, chisel, knife or scraper;
- Paint remover, brush;
- An ax or something similar to create serifs;
- Drill, hammer drill, grinder with nozzles.
Once everything is ready, the next thing you should pay attention to is the type of paint you are dealing with. Depending on this, you will need to select options for action and choose a specific method in which work will be carried out to remove old paint from the wall.
Types of Coatings
Depending on what paint you have to work with, you will pick up the inventory and the option of dealing with it. If we are talking about water-based paint , it is important to know its specificity. This coating dries quickly, does not smell, and after drying leaves a film that is difficult to remove from any surface.
In order to remove such paint, you need to prepare tools, among which: gloves, work clothes, a respirator, masking tape, a spatula, a fleecy roller. Starting work, you need to prepare yourself and the room itself. To work conveniently, it is necessary to free up space from furniture, and place polyethylene on the floor. In order to remove water-based paint, it is important to moisten the surface with ordinary water. An alternative would be an iodine solution.
All this will allow the paint to soak and it can be cleaned with a spatula. If you succeed, then you are on the right track. When moisture or iodine does not absorb into the walls and fails to work, you need to approach from the other side. For water-resistant paints, a spatula and a hammer will be required, the work with these tools will be performed in the same way. If you find it difficult to work this way, you can use a construction hairdryer.
When working with it, it is important to protect the face and respiratory tract with a respirator. Using a hair dryer increases the risk of inhalation of harmful paint fumes from walls and small particles. If you work with a spatula, but it does not peel off the paint, but simply glides over it, then you need to take a hammer and tap on the wall itself, and only after that use a spatula.
If the work is done on the ceiling surface, then to remove the water-based paint, you need to use a wash from the store, which in its composition has potent substances that allow you to effectively deal with layers of old paint. For such work, it is important to open the windows and doors so that the room has natural ventilation.
If you need to remove oil paint , it is important to know the features of this coating. They often use it in order to decorate the space. To clean oil paint is often not easy and sometimes you have to apply a whole range of measures.
To work, you will need such tools: several spatulas with different sizes, rags, a wash with a strong chemical composition, a grinder, sandpaper, a soldering iron.
Using a wash, the first thing you need to do is open the windows and doors, creating a good draft in the room.
Hands are protected with gloves, and a respirator is put on the face. The chemical must be applied to the wall and left there for as long as the instruction suggests.
It will be possible to remove the wash together with the paint with a rag. If at one time you were not able to remove the entire coat of paint, then you will need to carry out a second procedure again. When the paint is already old and begins to crack, then its removal is done with a spatula, the size of which is selected according to the situation. In difficult to clean places, work is best done with a small spatula.
In the event that the spatula did not help, then you can take a building hair dryer. He will heat a small section of the wall, after which it must immediately be cleaned. The most effective is working together - so that one heats up, and the second cleans the surface of the wall.
When working with a grinding machine, it is easiest to remove the old layer of oil paint, using a spatula in addition to the machine. On the machine you need to put on a nozzle with large emery paper and start polishing the wall. The fewer layers left, the thinner sandpaper to use. This option, although effective, but very dusty.
In the event that you have to clean the textured painting , then here you can use any method from the previously listed. An uneven coating will not allow you to conveniently work with a spatula, therefore it is better for him to highlight the auxiliary role. The use of a water-based emulsion can also be on the textured finish of the walls, which should immediately focus on how and with what you will remove the old coating.
When you need to remove acrylic paint , the process will be a little easier and faster. You will need to take a brush with a metal pile or sandpaper and actively remove a layer of paint from the walls. In this case, there will also be a lot of dust, therefore it is important to protect the eyes and respiratory organs.
To get rid of old paint in the apartment, you need to choose the right option to deal with it. In the kitchen or bathroom, oil paints are most often used, which cannot be washed off, because they are moisture resistant. The best tool in this case is cleaning the surface with a power tool and an appropriate nozzle.
An option to combat the old paint may be to use a stripper - a substance that can remove the paint layer from any surface. The cleaning process is fast enough, but there are some disadvantages. Substances have a high level of toxicity, therefore it is important to be careful and adhere to all necessary safety measures.
Another option to quickly clean painted walls involves the use of heat treatment. A building hairdryer or a Soviet iron will cope with this task. The main principle of action is the softening of the paint, after which you can clean off an unnecessary layer of paint using a scraper.
Another option that can be used involves cleaning the concrete wall from paint with a grinder or grinder. The painted surface can be removed layer by layer without any great effort or harm to health. This is an environmentally friendly option, safe for humans, but it has a significant minus - a huge amount of dust in the process.
If you have to work with the ceiling and wash white, then it is best to use a liquid and a fluffy roller, which can be used to soak the ceiling. Depending on the thickness of the plaster layer and the duration of its application, the soaking time may be different. Once the top layer has become soaked, it can be scraped off with a spatula.
Each option has its pros and cons.
Some carry the risk of chemical poisoning, but save you from washing away the dust. Other methods are sparing attitude to health, but much more dirty. These were the main points that you need to know when choosing the type of work during the repair.
This option involves working with any tool to achieve a good result. You can work from any point on the wall, gradually clearing everything that is on it. A grinder or a drill with a brush are the most effective options for such work.
The work has to be dusty, therefore it cannot be started without a respirator. In order to somehow reduce the amount of future debris, you need to wipe the work wall with a rag soaked in water. It is best that an assistant who does not work with a power tool do this, which will reduce the risk of dangerous situations. In addition, safety measures include wearing gloves so that the tool snaps tightly in the hand and does not slip.
In inconvenient places, such as sockets and switches, work is carried out using a chisel. If it does not clean the paint well, then it needs sharpening, which will need to be done from time to time. If after cleaning you do not plan to smooth the surface of the wall, then it can be cleaned with sandpaper, and then evened with putty.
When all work is completed, you need to vacuum well in the room both on the floor and on the wall, where the paint was removed. After this, a thorough wet cleaning is carried out to prevent the ingress of harmful substances from the paint into the human body.
In order to quickly and efficiently remove paint from a concrete wall, you need to use a special wash, which is applied to the surface and aged for some time. This option is suitable for both oil and acrylic paint. As soon as the top layer softens, you can begin to clean it.
For all the simplicity of work, this option also has drawbacks. The first of them is the high cost of drugs of this type. The second involves a special disposal of waste, because they contain a huge amount of toxins, which, in turn, makes itself felt terrible smell. In addition, this option is available for those surfaces that are painted just once. Otherwise, for each new layer, a new solution will be applied and the old paint will be removed, and so on to the very base.
In order to somehow reduce the cost of a chemical solution and reduce its harm, you can prepare such a mixture yourself. To do this, you need a little more than a kilogram of quicklime, 0.5 kg of calcium and water. All components are mixed and then applied to the wall. After twelve hours, you can easily remove the old paint coat.
The simplest and most effective option is to process the wall where you want to remove the paint using a building hair dryer. When heated to a high temperature, the paint softens and is easily removed. As soon as the hair dryer has acted on the paint before the formation of bubbles, you can begin to remove the unnecessary layer of paint with a spatula. It is very convenient in this way to work in places near switches and sockets.
Of the minuses of this method, it is possible to note a small area that can be heated at a time, and, accordingly, a slow flow of work; Do not work near wires and wiring so that they do not melt under the influence of temperatures.
It is important to work very carefully, because from overheating, the paint may catch fire and a fire will begin.
When exposed to high temperatures, harmful substances evaporate from the paint, so do not forget about the respirator.
In order to easily clean the walls of old paint, you need to choose the right option. With the right effect on the wall or ceiling, the paint will lag quickly, and the surface of the wall will not be damaged and you will not need to putty it and level it.
If the old layer is quite even and there are no traces of cracks on it, then you can simply update it and the room will take on a new look.
In this case, it is important to pay attention to greasy spots that may be on the wall. If there are any, then it is important to reduce them, otherwise they will appear on fresh paint. To prevent this from happening, you will have to wipe the spot with a stain, putty it, and only paint this field again.
Alternatively, you can still use chalk. If you rub a place with a stain with a clean piece of chalk, then the greasy stain will be absorbed into it a little. Repeat the procedure until the stain completely disappears. You can try to wash a greasy stain with a detergent that fights all kinds of stains on surfaces.
Work with paint should be carried out taking into account the type of coating. For some, a tough effect is needed, for others, a delicate one. The same principle works when cleaning old paint from walls. Based on what exactly you want to get, there is the use of certain methods and methods, which in the end will give you the desired result.
