As soon as the repair is started, each time we ask about whether it is necessary to remove paint from the walls and which way to choose.

A few decades ago, in each dwelling, the main finishing material was oil paint. It was fashionable to paint the walls with paint, so in the bathroom, in the kitchen, in the corridor and even on the ceiling, there was paint on the walls. They used oil paint or enamel in those days for staining walls. Every year, the paint was gradually eating so much that now it is very problematic to remove it from the surface.
Ways to clean the walls
There are several ways to clean walls from paint, each is laborious. And the most difficult thing in repair is to remove old paint from the wall.
Let's look at the methods of cleaning the surface from paint:
- mechanical;
- chemical;
- heat treatment.
The mechanical method is often used, although it is very laborious and not as effective as other methods of cleaning the surface from the old paint. In short, the process looks like this: you need to take a spatula or any other tool with a sharp end (you can scraper), sandpaper coarse -grained paper is also suitable. The paint from the walls is removed, cleaned, removed with layers. As you like, just to clean the surface from paint faster. The method, as already mentioned, is very laborious and does not always give a positive result. So you can prepare the room for decoration for weeks.
The chemical method speaks for itself - special washing and other mixtures are used. The remedies for cleaning the walls are different: liquid, semi -liquid and in the form of pasta. Solded ready or require breeding in water. Some are applied with a thin layer, some must be applied with a thick layer. The main task of such a chemical is to soften the surface, so that later you can clean the paint. The aging time is different, usually several hours are allocated for such a procedure. Each material also has different abilities, some manufacturers guarantee that washing will cope with 10 layers of old paint. The remains of the product must be cleaned with the paint that remains on the surface.
Such washing with a brush or roller are applied. Time is withstanding (indicated in the instructions), and then softened paint must be removed with a spatula. This method, of course, is faster than to remove the paint manually, only chemicals are very toxic. Therefore, you need to work in a mask and gloves, as well as constantly ventilate the room.
And another way to clean the surfaces and walls from paint is thermal treatment. This method is effective if you need to quickly clean the wooden surface from paint. A building hairdryer or a soldering lamp is used for these purposes. It all depends on the area of \u200b\u200bthe processed area. We will return to this method in more detail in order to study deeper the thermal process of cleaning walls from old paint, but for now let's prepare the necessary tools.
Thermal cleaning of walls from paint. What needs to be prepared from tools
Repair - the work is responsible and you need to immediately prepare all the necessary tools and materials so that everything is at hand. If something is missing at the most crucial moment, then you have to stop, and then start all over again. Therefore, in order to immediately cope with the task, you need to prepare tools and materials.
What can come in handy in the work:
- a few spatulas;
- brush for cleaning walls with hard bristles;
- enlargon coarse -grained paper;
- knife;
- screwdriver;
- construction hair dryer or soldering lamp.
Also, do not forget about safety measures: you need to cover the hair with a hat or scarf, put on a bathrobe, work better in gloves, and your eyes will help protect special glasses.
How to remove paint
It is known that if you heat enamel or oil paint, then it is first swollen, then foams and gradually exfoliates from the surface. This allows you to quickly get rid of the old coating. Therefore, if the plot is small, then it can be used for heating the paint by a soldering lamp, if the plot is large, then it is easier to work with a building hairdryer.
The principle of operation is very simple: you need to warm up the paint, and then remove it with a spatula. Fast and simple, if you need to process a small area. This method works well if you need to get rid of the old paint on a wooden surface. Especially when you need to put the window frames and wooden doors in order. Remember that when heated, the paint emits toxic gases, so you need to work in a well -ventilated room, and if possible, then take the door or window blocks to the street.
How to remove paint from the walls:
- the thermal method is good that you can quickly clean the surface of the layers of paint, only you have to warm up small areas, clean them, and then move on;
- in order to remove the old paint, you need to arm yourself with a construction hairdryer, turn it on and direct a stream of hot air to the processed surface;
- cleaning walls with hot air must be performed until the paint softens, and then remove it with a spatula;
- you work without interrupting - if you hold the hair dryer with your left hand and direct the stream of hot air on the wall, then with your right hand you can clean the softened paint, gradually moving and cleansing the entire surface;
- what did not succumb the first time, you need to try to remove again. To do this, you can use a soldering lamp or turn on the construction hair dryer again. Clean the remains of the paint with a spatula, a sharp knife and treat the entire surface with sandpaper at the end.
On the advantages and disadvantages of the thermal method of wall cleaning from paint
The thermal method of removing the paint is very effective because you can quickly process a large area and clean the wall of the old paint. But there are some features that you need to know about. So, it is almost impossible to remove the paint from the plastic surfaces, because when heated, the plastic is immediately melted and deformed. So if you need to remove paint from such surfaces, then choose other methods.
And yet, the paint heats up and emits toxic substances, and the use of rapidly heated devices (soldering lamp and hairdryer) is unsafe.
Disadvantages of the method:
- The paint emits toxins when heated.
- Not all surfaces can be cleaned with this method. Plastic surfaces, metal and concrete are not subject to heat treatment. If you need to remove the paint from the plastered surface, then you will also not succeed.
- In places where there is electrical wiring and sockets, this method is not suitable.
And it is also necessary to consider that there are types of colors that, when heated, are even better adverse with the wall or other surface. Therefore, if you do not know what paint the walls and ceilings were painted, as well as doors or window frames, then you first need to try to warm up a small area and see the result. If the paint melts, then you can proceed to work, and if it is immediately baked, then you need to select other methods of surface cleaning from the old paint. And be as careful as possible, because some types of paint are burning with strong heating.
The pluses of thermal cleaning:
- With this method, there is no dust, hot paint is removed with layers.
- Quick surface cleansing of paint. The thermal method of getting rid of paint can be chosen if you need to get rid of the old paint on wooden surfaces. For example, if houses from year to year, wooden window frames or floors were painted with oil paint or enamel. Then you just need to warm up the paint with a construction hairdryer and clean the old layer. The surface is ready for new staining.
If you update the old window frames, then naturally, you need to remove the fittings (handles, locks, etc.), as well as remove the glass. Before starting work, you still need to wipe the surfaces to clean them of dust and dirt.
About safety precautions
If there is no experience with heating devices, you need to try to be careful and work as accurately as possible. If you work with a soldering lamp and a stream of flame was directed at the skin, then with short -term exposure, nothing will happen, but if you keep it for a long time, you can get burns. If you work with a building hairdryer, then some parts are heavily heated. In order not to get burns, you need to be as careful and careful as possible.
In any case, regardless of which method was chosen, you need to use the protective equipment: put on gloves, glasses or hold a transparent shield in front of you, and remove your hair under a hat.
