The law of any repair: health, first of all. When the question is solved, how to remove old paint from the walls, protective equipment is prepared:
- Protective glasses;
- Disposable film raincoats;
- Construction gas masks.
Methods for removing paint from walls
There are 3 ways to remove paint from walls:
- A chemical method in which washes, gels and reagents are used to remove;
- Mechanical method. using manual and electric tools;
- Thermal method. using open flame.
Before choosing a method of dismantling the paintwork, an analysis of the painted surface is performed. To do this, take a sharpened knife (kitchen or painting) and try to apply deep scratches with maximum effort. If the knife does not penetrate further than the first layer, then the case is difficult, and you will need to experiment with all the removal methods.
Otherwise, the mechanical method will be sufficient.
Mechanical removal method
To clean the walls of paint you will need the following tool:
- Paint knife;
- Spatula. 70 or 100 mm;
- Thread roller;
- Chain-nozzle on a drill for removing paint;
- Atomizer. 1-2 liters;
- Vacuum cleaner building;
- Small angle grinder;
- Hammer drill;
- Diamond grinding disc;
- Petal emery disc;
- Emery grinding disk;
- Conical tourniquet brush for angle grinder;
- The widest paddle blade;
- Concrete bit perforator;
- A special nozzle for a notch. butchard.
The situation, how to clean the wall of paint, requires the right approach. Therefore, the withdrawal begins with the simplest methods. With the help of a scraper, knife and spatula, the layers are removed on the swollen places and cracks.
Further, the most effective layers are used to peel off the layers.
Cleaning the walls of old paint is a very dusty job, which is convenient to do together. One is directly involved in removal, and the second is in auxiliary work. To reduce dust, wet the walls with a spray bottle.
And for quick dust settling, water is sprayed into the air. When working with an angle grinder, you can use a vacuum cleaner, taking dust directly from under the nozzle. Excluding winter time, the windows in the room should be open.
manual removal of paint. the process is long
The above technology for removing paint from walls is well suited for not strong painted surfaces: plasterboard partitions and plastered walls. But how to remove if the angle grinder does not cope? Then the punch is included in the process. The only serious drawback of this tool compared to the angle grinder is its impact force. When cleaning, the plaster layer will suffer and further alignment will be required.

This is especially true of the bathroom and kitchen, which were repaired in Soviet times.
Not every artist knows how to remove paint from the walls in the bathroom. There are frequent cases when the walls of the bathroom were covered with layers of paint for decades. Therefore, in such situations, the enamel is removed with an ax or punch.
Tip: grind a wide spatula for a punch, like a chisel, and you can remove any paint that bothers you.
The most difficult case is considered to be the problem: how to remove paint from a concrete wall. First, try to remove the enamel angle grinder with various nozzles or a rotary hammer with a spatula. If the effect is not enough, then you can try to use the Buchard. a nozzle for a punch, resembling a kitchen hammer for cooking chops. Advantage of Buchards: removes any paint from concrete walls. The combination of colors for walls and ceilings?
Disadvantage: 3-5 mm of the wall surface is removed along with enamel.
Thermal removal method
Use this paint removal method only in well-ventilated areas. To improve ventilation, an artificial draft can be used with 2 summer riser fans. One fan is installed at the window and directs air, saturated with chemical odors, outside the premises.
The second is installed at the door to pump clean air into the room.
At least good respirators should be used to protect the respiratory system, since the excreted ashes and soot fit well and permanently into the lungs of a person. Eyes protect with glasses.
Thermal tool required to remove paint:
- Gas burner with gas cylinder;
- Hair dryer;
First, one person burns a small portion of the wall surface with paint, and the second, immediately after it, cleans with a scraper, putty knife or chisel. Thus, firing is performed until the wall is completely cleaned.
Using a hairdryer, the same procedure takes an order of magnitude longer.
The disadvantage of this method is the inability to use the burner in residential apartment buildings, since burning smell will cause fair indignation of the neighbors.
Remember: the thermal method is more dangerous to health than the mechanical method, since it is very toxic.
How to clean the walls of paint if the above methods do not help? The chemical method remains. With this method, special removers in liquid and gel form and solvents (such as white spirit or acetone) are used to remove the paint.
Work with chemicals should be fully equipped: gas mask, gloves, glasses and a raincoat. The room should be well ventilated.
Liquid products are applied to the walls with a spray gun, and thick gel rollers and brushes. Depending on the manufacturer’s instructions, they wait a certain time after application and try to remove the dissolved expanded enamel. Means for removing old oil paint from the walls? The procedure is repeated until completely cleaned.
When the wall has become clean, it should be treated with an acidified solution (water, citric acid or vinegar). Remember: take care of yourself and your health for family and friends.
- Oil coatings, in contrast to nitroenamels, are removed much worse, since they are more flexible and can not fall behind layers, and very often simply rub on a plane when trying to scrape them. The same can be said about the polymers, which are flexible enough, especially since they were applied on top of the primers, which makes disassembling much more difficult.
These two groups of models differ in the following ways: by weight, professional punchers are much heavier, by productivity, the difference in power is not in shock. The difference is not in the design features not in the number of devices. For this reason there will be a difference not in cost.
Professional punchers are more expensive.
The situation, how to clean the wall of paint, requires the right approach. Therefore, the withdrawal begins with the simplest methods. With the help of a scraper, knife and spatula, the layers are removed on the swollen places and cracks. When the light spots are cleaned, proceed to the removal of paint using an angle grinder with nozzles. In small areas of the surface, each nozzle is tested.
Further, the most effective layers are used to peel off the layers.
Next, we clean off the paint itself with an ax, here the main thing is to choose a suitable tool angle, so that the paint is brushed off as best as possible.
If you work with an angle grinder, then you should expect a lot of dust. It turns out that you will work for a minute, and then wait twenty minutes for the dust to settle. Quite an impractical and long way!
When using a drill, you can use three different nozzles: a crown nozzle for working with bricks, a brush and a paint pickup consisting of three chains with thirteen links.
How annoying it would not sound a scraper when it’s factory nozzle, occasionally when suitable for cleaning, this is not practical evidence. The creator of this article was faced with a situation where the cement-sand plaster in the bathroom of the room was painted with alkyd paint.
Such a device is made in the form of a rotating brush with a metal bristle and while the wire is new (not bent), the processing is quite effective, but not for any paint. it happens (especially with oil coatings) that the metal bristle is not able to peel off the paint, but only smoothes it over the surface.
Such a wash is applied with a brush or roller to the painted surface of the wall and left for some time, which is necessary (usually 10-15 minutes) to soften the paint. Then, the swollen paint, together with the wash, is easily removed with a scraper or a hard spatula.
