In addition, the coating with water-based paint will not be relatively expensive, and the color is selected independently with the help of special colors.

wash the water-based paint

If the paint layer on the walls and the ceiling is held tight, there are no delaminations or areas on which the paintrzhitsya not very good, then it is not necessary to wash off. In this case, a layer of fresh paint is applied over the old one. Previously, debris and dust are removed from the wall, dried and primed. Primer creates a high-quality adhesive layer, on which the new coating will lay evenly and qualitatively. Primers on the basis are not divided into several different types, for water-based paint use acrylic.

If the layers of the old paint do not hold fast, fall off, in many places bubbles are formed, then the paint should be washed off. Also, the water-based paint is removed if it is planned to overhaul or the surface will be covered with another type of materials incompatible with the water-emulsion.

Another case that will require the removal of old layers of paint - repainting the room in a different tone. If the color of the ceiling or wall covering is darker than the one that is planned to be applied, then it must be removed. Darker colors will appear through the light, no matter how many layers of paint are not applied from above. How to wash off the paint from the walls, is described below.

How to wash water emulsion paint with water

To remove walls and ceiling of water-based paint, you need patience and some tools:

1. For work on the ceiling or high walls, you will need a stepladder or a high stable stool.
2. Wide trowel with metal base.
3. Roller with long handle.
4. Cuvette or basin.
5. Brush with metal bristles.
6. Polyethylene film or newspaper.
7. Glasses and respirator.

The water-based coating on the walls and ceiling is water resistant and not water resistant. In the first case, the method of removing the paint is slightly more difficult and it will be described below. For the non-waterproof coating, the following method is suitable:

1. Close all surfaces and indoor furniture with newspapers or a film.
2. The eyes and respiratory organs of the person doing the work are protected with glasses and a respirator.
3. Pour warm water into the container.
4. In water, wet the roller and conduct it on the coating layer, which must be removed.
5. Leave the coating to soak for 10-15 minutes.
6. Remove the softened paint from the walls with a spatula.

When you apply water to the paint, you do not need to wet the entire wall or ceiling at once, as long as the queue for removing the paint reaches them, the coating will no longer be soft. Soak small areas and so move along the entire wall.

How to wash water emulsion paint with thermal and mechanical method

There is a simple and effective way to remove water-based paint from walls and ceiling, but it provides for the availability of specialized tools. In the first case, a drill with a grinding nozzle is used for this, in the second - a building hair dryer.

A grinding bit for a drill is a round brush with a metal bristle. This add-on is sold for the tool in any store of construction and household materials. With the help of such a nozzle, remove thick layers of paint and a waterproof coating, which is not amenable to conventional washing. In this is the advantage of using a drill. Disadvantage - during the work is allocated a large amount of dust. Also, to remove the paint, use a grinding machine.

Thermal method - removal of coating with a special construction hair dryer. Such a device works on the principle of a household hair dryer, but the air jet emitted by it has a high temperature. This device warms up small areas of paint, they crack and move away from the base. Further, the heated coating is easily removed with a spatula.

After finishing the work with a hair dryer, the whole surface is carefully examined and cleaned up again where the marks of paint remain. As a rule, small areas of a thin layer of paint remain, such defects are removed using sandpaper or a metal brush. Next, the surface is thoroughly washed or vacuumed to remove the dust that has settled on it. The thermal method of removing the paint is suitable for thick layers of paint and waterproof coatings. Has only one drawback - the need to purchase a construction hair dryer.

How to wash off water-resistant paint

1. The surface often covers not with ordinary water-based paint, but with water-resistant paint that can not be washed with water. Especially often it is used in bathrooms, in the toilet and in the kitchen - in rooms with high humidity. Determine the resistance of the paint to water is very simple - treat it with warm water and leave for 10 minutes, if after this time the paint does not begin to depart from the base, it is water resistant and other methods should be used for removal.
2. A hard brush with metal teeth is used to remove the water-resistant paint. With this tool, carefully clean the top layers of paint, trying to leave a large number of scratches on it. These scratches penetrate the moisture and soften the paint. When the whole surface is scratched with a brush, it must be moistened with plenty of warm water and left for 10 minutes. This operation is carried out several times - water is applied and left so that the paint is well soaked and swollen. It is mandatory during the procedure to well ventilate the room, this will speed the departure of paint from the surface. Complete this process of removing the paint with an ordinary spatula, removing them all layers.
3. Effective for removing water-resistant paint wallpaper glue or a regular paste. It is applied to the old paint and any unnecessary thin paper. Glued very carefully so that the paper is firmly adhered to the paint. Then the surface is left to dry. When the glue is dry, the paper is peeled off, using a spatula. At the same time with it, easily removes the layer of paint. At the end of the work, the ceiling is carefully examined and the places where the paint remains are removed.

Two more methods have already been described above - thermal and mechanical, using a construction hair dryer or drill. Each of the described methods is effective, the choice must be made only based on the availability of certain tools and materials.

Other ways to remove

water-based paint 1. Another answer to the question "how to wash off water-based paint" is to apply various chemical additives, specialized or usual household items. For example, if you add 200 ml of iodine to a bucket of water, it will be much easier to remove the paint:

• removes the water-based coating with a soap solution. It is applied to the surface with a brush or smears paint with soap and then rinsed off with a cloth. Some tips:
• if the coating is acrylic based, then add salicylic acid or vodka to the soap solution, since alcohol dissolves polyacryl;
• if the coating has impurities of latex, then dichloroethane or chloroform is added to the water.

These supplements emit a large amount of toxic substances, therefore it is necessary to use a respirator and carefully ventilate the room during the whole work.

2. Another simple way to get rid of the old layer of paint - hide it behind panels or a false ceiling. Modern building systems eliminate the need to wash the walls to give them a fresh look. Another progressive method of getting rid of the old coating is the paint destroyer. It is a gelatinous mass that is applied to a small area of ​​washable paint, wait for the time specified in the instructions, wipe with solvent 646 and then scrape off. This method is convenient for lack of dust during the work, but the execution will take a long time.

3. Alternative to paint destroyers - washings. In the composition of these substances a large amount of a solvent based on dimethylchloride, formic acid, isopropyl alcohol or other organic substances. They are absolutely safe for health and the environment, as they completely decompose in a short time. On 5 m2 of the surface, on average, 1 liter of material is needed. Washing is effective both on old coatings in several layers, and on waterproof paints.

Removing agents for water-based paint

Many countries and brands offer customers a wash-out of water-based paint. But not all of them are worth buying and using in their homes. Some products have harmful substances, such as hydrochloric acid. They are effective for removing paint, but will cause significant damage to human health. It is necessary to carefully read the composition when buying such a product. In general, two manufacturers stand out:

1. Set Boya Sokucu( Seth Boy) from Marshall Boy( Marshal Boy) Turkey. This product effectively softens and removes water-based paint of all types. It is used on bases of concrete, wood and metal. It is forbidden to use on plastic substrates. The composition of the product has an interesting combination of various organic substances, because it is as powerful in the job as it is safe for health. The application looks like this - the product is applied to the paint, left for 15 minutes, and then remove the coating with a spatula. The final treatment of the wall is carried out with a cellulose solvent.
2. Flushing paint "Manor".Has a gel-like structure, suitable for removing all types of water-based paint from wood, concrete and metal, but not suitable for plastics. During operation, the vapors of the substance are released in minimum quantities, safe for humans. Softens the paint for 10 minutes. Finishing of the surface is carried out with any degreasing agent.

How to clean water-based paint from garbage

During the repair, there are situations when a fresh can of paint turned out to be littered and spoiled or garbage got on a fresh layer of paint. Often this happens because of poor quality removal of debris and dust after washing off the old paint layer. In this case, it is not necessary to buy a new paint jar or cover the wall with a new coating layer, there is a way to remedy the situation without such global measures.

1. If a new paint pot was found to be littered, then all particles must be eliminated. Large pieces are taken out of the paint with your hands or with improvised means. Medium-sized rubbish is removed using a sieve - I pass paint through it. It is not recommended to use littered paint, since all particles trapped in it will spoil the appearance of the coating and break its integrity, which will shorten the service life.
2. If the colors of different colors are mixed, then they are thoroughly mixed to begin with. Then they select the necessary colourant and gradually add it to the spoiled paint to restore its original tone. This action is carried out only if the colors of the same type are mixed. If, however, polyvinyl acetate or, especially, oil paint gets into the acrylated water-emulsion jar, it is considered irreparably damaged.
3. The most unpleasant situation - garbage got on a fresh layer of paint. In this case, it is carefully peeled off with a fine-grained sandpaper and another layer of paint is applied. In case of large and very noticeable contaminants, the paint must be applied again. To avoid such an unpleasant situation, it is necessary to carry out the preparatory work for the flushing of the old coating from the surface, wash the wall after removing the paint or wallpaper and thoroughly wipe it with a rag. To clean the walls before painting, the usual or washing vacuum cleaner is effective.
