How to clean old paint from metal surfaces?

There are three main ways to remove paint from metal:

  1. Mechanical. The composition is cleaned off by applying physical force.

Mode of application:

  • foto7383-4the selected tool is included in the network;
  • holding it at an acute angle to the surface, clean the paint;
  • if the layer is thick, then use coarse nozzles with a large abrasive, as the work progresses, they are changed;
  • so that less dust is formed during cleaning, the surface is sprayed with water - for this it is convenient to use a spray;

  2. Blowtorch... She is a source of open flames. Under its influence, the paint burns out. It remains only to clean it off with a brush.
  3. Iron. They heat the surface of the metal through some material, for example, through a foil. In this way, it will be possible to work out only small surfaces. The method is considered the most time consuming and ineffective.

How to remove paint:

  • foto7383-5remove all unnecessary items - there should be nothing on the working area except the surface to be worked on;
  • remove dust and dirt from metal;
  • prepare a heating device;
  • calcine the paint evenly around the entire perimeter of the metal product, then you can start working on individual zones;
  • the softened composition is cleaned with a brush or spatula.

Paint may still remain on the metal surface after cleaning is complete. It is removed with a solvent. It can be applied only after the product has completely cooled down.

Do not thermally remove paint from cast iron, brass and aluminum radiators. It is forbidden to glow decorative thin-sheet elements, especially those that form a composition with other materials.

How to quickly clean with chemicals?

How else to wash off the paint? The use of professional washes allows you to quickly get rid of the coloring composition, regardless of its type.

In practice, various solvents are used, including:

  1. Aerosol KUDO... The cost of 520 ml is 230 rubles.
  2. Veslee Remover Aerosol... The cost of a composition with a volume of 450 ml is 180 rubles.
  3. Cleanser Syntirol... For 1 kg of funds, you will need to pay 470 rubles.

Mode of application:

  1. foto7383-6Wash off all impurities from the surface to be cleaned.

  3. Apply chemical reagent. It is most convenient to use aerosol cans.

    The regular wash is poured into a suitable container and spread over the metal with a paint brush.

  4. Leave the composition to act. The exact time is indicated in the instructions for use for the selected product. It can be from several minutes to several hours.
  5. The swollen layer is removed with a spatula and a brush with stiff bristles.
  6. The metal surface is washed with a solvent such as gasoline and then with water.

All washes have a pungent odor, so you need to work with them outdoors or in rooms with good ventilation.

How to remove from the gate?

To clean the paint off metal gates you need to perform the following sequence of actions:

  • remove all contaminants from the metal surface;
  • walk along the gate with a grinder - the nozzle must be selected depending on the number of layers of paint;
  • work out hard-to-reach places (joints, welds, hinges) with a brush with metal bristles;
  • apply a solvent to the gate surface - this will get rid of the dye residues and degrease the metal.

After such cleaning, the gate will be completely ready for further processing.

If it was decided to remove the coating with a wash, then choose a thick composition: gel or aerosol. The gates are located vertically, so liquid products will drain from them and will not have the desired effect.

You need to clean the paint on a sunny day. Rain may cause work stoppages.

Features of the removal of different types of paints and varnishes

Any paint can be removed mechanically, thermally or chemically, but sometimes some methods are preferred.

Paint typeRemoval method
OilA thin layer can be removed with any remover, for example using acetone. A thick old layer requires mechanical cleaning. The most difficult areas are burned out.
AcrylicThe paint lends itself well to solvents and washes. To improve the efficiency of work, the surface should be cleaned.
PowderThe most effective way to remove paint is to burn it out. If this method cannot be applied to the product, then they resort to chemical agents, for example, Fail-4 or Remover.
Aerosol (from a can)You can get rid of this paint with sandpaper or a wire brush. For high-quality removal of the composition, the surface is treated with a solvent.

The most common mistakes

When removing paint from a metal surface the following mistakes should be avoided:

  1. foto7383-7Using a hot air gun or burner indoors. The paint will release toxins when heated, so poisoning cannot be avoided. Such work should be carried out in the fresh air.
  2. Firing of products from brass and cast iron. When heated, these metals scale and become brittle. This will lead to their rapid destruction.
  3. Work without personal protective equipment. Failure to follow basic safety measures increases the risk of injury.
  4. Mechanical cleaning of thin metal sheets. Pressing too hard can damage them. The product loses its shape or dents appear on it, which will be difficult to straighten.

In order to avoid mistakes when performing work, you need to know what kind of metal the product is made of and what type of paint it is coated with.

Important recommendations

When removing paint from metal you need to use the following recommendations:

  1. Observe safety precautions. Hands, respiratory organs and eyes need protection.
  2. Take care of cleanliness. Dust will be less generated if the surface is sprayed with water before mechanical cleaning.
  3. Do not overheat the paint so that it does not catch fire. You can start applying a metal remover or solvent only after it has cooled down. Such liquids are flammable.
  4. In order not to damage the surrounding surfaces, they are covered with matter.
You can enhance the rinsing effect by creating a steam effect. After applying the composition, the surface is protected with polyethylene. However, the cellophane and the remover should not come into contact.
