How easy is it to remove old paint from the walls?

Having started repairing, many are wondering - how to remove old paint from the walls, without damaging the walls themselves, for example, in the bathroom? And also how can this be done easily and quickly, how to remove water-based emulsion, and how to remove oil paint from the walls? It is logical that there is no point in gluing new wallpapers directly onto the painted surface: not only is it a priori uneven, so the bright dark colors of the colors can shine through thin paper of light colors. And, of course, you have to tinker with the old paint if you plan to repaint the room.

In total, in the modern business of creating interior solutions, there are four main types of paint: oil, water-based, acrylic and enamel. Additionally distinguish textured samples spreading by various effects or incorporating inclusions from other materials that create irregularities. By the way, removing such paint from the walls will be the most problematic. Types of application paints are also distinguished - for example, aerosol samples.

So, the types of paints used in decorating the interior, including the bathroom, are in order from samples that are quite difficult to remove to easily removed:

1. textured samples of any type and composition;
2. oil;
3. water emulsion;
4. acrylic.

How to remove old oil paint from the wall?

Oil paint, especially used for exterior paintwork, is very difficult to peel off the surface. In the past, when repairing, for example, a bathroom, they even preferred to simply cover the old layer with a new one. It is logical that this approach will not be appropriate in all cases, and sometimes it is necessary to completely remove the old layer.

Tip

Before removing the oil paint, it is worth placing several basins in the room with warm salted water. So you can avoid the spread of unpleasant odor of this type of paint. The same advice works if a new layer is applied.

On a small scale, oil paint can be easily removed using the following substances: white spirit, pinene and other solvents, turpentine and ammonia will be less effective. All of the above compounds are volatile and extremely odorous, which means that you will have to carefully close the neighboring rooms, and also work in a respirator. A lot of solvent will be needed, and the result will be scanty, therefore this method can be left only for those cases when the painted surface is very small, literally dotted, and not on all walls of the bathroom.

1. mechanical;
2. thermal;
3. chemical - using professional reagents.

The simplest way to destroy the old oil paint on the walls in the bathroom is as follows: a small area is heated with a construction hairdryer, and then it is cleaned manually with a spatula. In this case, the paint will have to be removed for a long time, using considerable physical effort. In some cases, you may even need a small hatchet to chip the layer. You will have to work with gloves, overalls and, best of all, with special glasses. Care should be taken in advance to remove wiring on the walls and the rest of the neighbors. The condition of the bathroom walls after such dismantling of paint from the walls leaves much to be desired and requires leveling.

other methods

A more civilized way is to use a small construction grinder. Alignment of the walls after such interference in the interior will be minimal. In addition, in the bathroom, immediately after removal, proceed with the installation of tiles or PVC panels.The method is noisy, also requiring special equipment and a certain skill.

In addition, an electric drill is often used as an oil-grinding tool. No noise can be avoided, mistakes too - if you had no business with the drill before. Professionals advise using special nozzles for dismantling. The nozzle of the "chain" has proven itself well. With minimal damage to the walls, the sample will quickly get rid of unnecessary old paint with the help of three segments of chains from 4-5 links. You can also arm yourself with a special crown used to work on a brick surface.

In general, the modern arsenal of methods for ridding walls of objectionable paint includes, among other things, less common methods - using improvised means. For example, a piece of paint is heated through a foil with a household iron, and then a spatula is also used.

Chemistry will help us

In order to remove the annoying paint from the walls of the bathroom mechanically, it is not necessary to know its composition. Drill and grinder will be perfectly removed including water-based paint. Things are even simpler with acrylic samples - special solvents for this type of paint will help you quickly and painlessly get rid of the paint layer. To use the chemical method, it is necessary to clearly distinguish between the type of paint: water-based, acrylic or oil-based - most likely, each type will have to be removed with different reagents.

The scheme of the chemical method is as follows: a special reagent is applied to the paint, leave the room and after some time of absence begin to remove the unnecessary layer with the same spatula. The difference from the thermal method, in which a building hair dryer or even an iron is used for the walls, is at first glance minimal. However, in reality, the chemical method will allow you to spend less effort, but you will have to spend on reagents. In addition, they will also have to be searched for in stores, as well as additionally purchased personal protective equipment, including special glasses and a respirator. Using ready-made reagents, it is not difficult to remove the layer from the walls.

Advantages and disadvantages of each method

Pros and cons exist in absolutely every method of dismantling the old paintwork. In absolutely every case, residents will have to leave the room for a while. During mechanical removal of paint from walls in the air, a suspension unsafe for health may form, in addition, having a rather pungent odor. In addition, you will have to warn your neighbors about the upcoming noise. A relatively silent method remains to remove the paint with a thermal method using a spatula, but in the same way no one is safe from dust unsafe for health and exhausting work. The chemical method, at first glance, seems simple - just apply the reagent with a brush and wait, and then easily scrape off the remaining paint. However, even a small amount of a special reagent can cause a burn and an allergic reaction, and careless inhalation can lead to more dire consequences. This category of funds is so toxic that it cannot be disposed of in the sewer of a residential building, which also creates additional difficulties and worries for the owners.

There is always an alternative to removing paint - it's the decision to leave it. The unsightly old layer is easily covered with PVC panels, wood paneling, solid wood and other types of coatings. In some cases, it is worth choosing a primer that will lie on top of the old paint layer and will serve as a grip for the new paintwork of absolutely any color and composition, and the old one will not shine through.

It is also worth taking care to facilitate your own work. With the mechanical method, it is highly recommended to use a construction vacuum cleaner that sucks in harmful dust.In all other cases, thick special gloves resistant to the action of reagents, a special protective suit, goggles and a respirator will help. When using the chemical method, it is strongly not recommended to use a cotton-gauze dressing instead of a special respirator. Secondly, it should be remembered that the universal magical method - applied the composition and simply wiped the surface from the old paint - does not yet exist, and no matter what means of removing the paint layer you choose, you will have to work with your hands to transform the interior of the bathroom or other room.
