In this article we will tell you how to shoot from the walls of the main types of paints.

Can I leave old paint

Many mistakenly suggest that if we apply a new paint on top of the old paint, even if you can solve the same color. However, in this case, the new coating will last several times less than its real operational period and will have an inaccier appearance.

At the time of the Soviet Union, it was very popular to paint the walls not only in the entrances, but also in the apartments - in the kitchen, in the bathroom and toilet. Therefore, in old apartments, you can still find traces of the former Soviet "design", from which people or do not want to get rid of, or believe that the old paint is a great way to get a flat surface for further finishing with modern materials. In some cases, it is, for example, if you plan to separate the walls with plasterboard, then the paint can not be removed. But if you want to repaint the wall, shove wallpaper or tile, the old coating must be removed. Otherwise, the tile or wallpaper very quickly will be twisted from the wall along with the old coating. Adhesion, that is, the adhesiveness with adhesive compositions, the old paint has almost zero, and therefore it is better not to try to glue something on top of her. The same applies to the plaster - this repair will live very long.

Not only aesthetic and practical, but also the sanitary side of the issue is important. Imagine how much dirt and bacteria has accumulated on the old paint, how many microbes gathered in its microscopic cracks, not visible to the naked eye. In such premises, where many years did not make repairs, the likelihood of getting sick or feel the malaise is much higher than in a new apartment.

Features of the removal of old paint

Depending on the variety and composition, the paint is determined by the way to remove it. So, some are removed very easily, and even professional builders will work over the others for several days. Also, the surface on which paint is applied is also played. Consider more in more detail.

Factors determining the method of removal of old colorful coating:

the nature of the surface on which the paint is applied;
further actions (what do you plan to do with the wall);
paint type;
old coating thickness;
existing tool;
financial factor (how much money you can spend on cleaning the wall).

There are only three types of paint:

water-emulsion;
oil;
acrylic.

It is more difficult to remove the oil paint, and for this you will use not only patience, but also special tools. Since this is the most problematic way, we will dwell on it in more detail and consider the process just below.

If you cannot determine how type of paint you have to work, you can experiment and choose a more suitable and fast way. It is better to do this in a small area of \u200b\u200bthe wall somewhere at an invisible place, for example, behind the cabinet or near the battery. Starting with gentle and simple ways, moving to more laborious.

Tools and materials

Before talking about how to remove paint from the walls, we will deal with tools and materials that may be needed:

the spatula is wide and narrow;
tassel with hard pile flat;
roller;
chemical agent for removing old paint (sold in construction stores);
protection tools (rubber gloves, glasses, respirator);
construction solid;
electrode with a brush nozzle;
construction hairdryer;
bulgarian with a set of nozzles;
water;
rag.

Removal of oil paint

As we have talked above, remove the oil paint from the walls is the most difficult. If you can, it is better to pay professionals and entrust work to them. If you want to save, you will have to work well with your own hands. We have prepared instructions and useful tips that will help you make work as quickly as possible and without errors.

In old apartments, there are often cases when oil paint has been applied to unwritten walls and ceiling. From such a coating to get rid of it is especially difficult, but if there is free time and the tools there is nothing impossible!

There are three methods for removing oil paint from the walls:

Chemical - paint removal with a special chemical solution. You can buy it in any construction store, but be careful - the tool is very toxic! Before opening the bottle, put on gloves, glasses and respirator. If the solution is able to corrode an old strong paint, then imagine that it will do with the skin of the hands or mucosa and the nose. Apply a means to the surface of the walls or the ceiling follows with a flat painting brush or roller. Movements must be in one direction. Cover the wall area with a uniform layer of means and leave for a while (read the instructions on the package). Pros of this method - speed. You can get rid of old paint for half a day. Cons - the caustic smell will dislike for a very long time, it is not recommended to remove paint in the nursery or in the kitchen (you still work with poisonous reagents). Another disadvantage is that there will be quite a lot of solution to process all the walls, therefore it is not necessary to speak about savings.

If you need to remove the paint from the board walls or floor, moisten the surface with water and pour the soda calcined. The layer should be rather thick - about 1-2 cm. Close the surface with a wet rag and leave for a day, periodically splashing with water. After that, the paint can be easily removed using a spatula.
Lime and sodium carbonate can also help get rid of old paint. It is necessary to mix 1.2 kg of negated lime with 400 g of carbonate (soda), add some water so that the consistency resembles a thick sour cream. The mixture is applied to the surface and left for 12 hours, after which the paint easily can be removed by the spatula.
And the last method of chemical removal - with liquid glass. Lubricate them with the wall, leave until complete drying, and then remove the silicate film. She will be filmed with old paint. If necessary, repeat the procedure several times.
Thermal is one of the most common ways. How to remove paint from the wall without poisonous chemistry - use the construction hairdryer. It warms up the surface so hard that the paint is melted and it can be easily removed with a spatula or scraper. This method is suitable for working with walls, ceilings, floors, doors, etc.

Useful advice: If you failed to get a construction hairdryer, attach a foil sheet to the wall and heat the paint with the iron until it becomes soft.

The thermal method cannot be applied where the wiring is released or in places with a fusible decorative coating (plastic). The construction hairdryer is ideal in cases where you can not apply a jackhammer or allow vibration (windows, glazed doors). However, this method has its drawback - the molten paint exudes a caustic poisonous smell, which also disadvantages poorly. During operation, it is necessary to wear glasses and a respirator.
Mechanical - Since the first two methods for removing paint leave an unpleasant poisonous smell, many prefer a mechanical method. It requires a special technique, it is noisy, laborious and not so fast, but the work is obtained very high quality. On the wall are made with an ax, then the surface is sprayed with water, and after absorbing the paint is considered the same ax, located under the tilt. As a rule, such a "grandfathers" method is used if the wall is planned to be tinted with ceramic tiles, since it provides perfect adhesion with adhesive compositions. The method is very laborious and more suitable for working with small areas in poorly ventilated premises (storage rooms, basements, etc.).

Modern construction equipment allows you to speed up the method of mechanical cleaning of walls many times. For this, a Bulgarian or drill is used with special nozzles. If you work the grinder, take the widest range and buy a good respirator - dust will be much. It is better to choose a grinder with an elevated vacuum cleaner to eliminate dust.

It is possible to remove the paint from the walls using an ordinary perforator with a chain nozzle. An ordinary chain of 13 links of 5 mm is taken with a thickness, attached to the central link, and 6 links on each side rotate and remove the paint. Cheap and efficient way. If on the one hand flew away, it is necessary to remove one link on the other side for the balance. When working with a chain, it is necessary to protect against mechanical damage (thick gloves, glasses, etc.).
