There are universal removers on sale, as well as those designed for certain types of powder paints. When purchasing, you should read the instructions. Removers have a liquid or gel-like consistency.

General rules

How to properly remove a layer of powder paint:

Before working with aggressive chemicals, wear personal protective equipment - gloves, goggles, clothing made of coarse durable fabric, a respirator. The work is carried out in a room with good ventilation.
Products from which paint needs to be removed are washed, degreased, and dried well.
Gel-like solvents are applied with a brush, roller or spatula. They do not drain and adhere firmly even to vertical surfaces. This way you can remove paint from floors, roofs, and large fences.
To clean small items, use the immersion method. The liquid wash is poured into a container made of stainless steel or other material that is not afraid of acids and alkalis.
It usually takes 15-30 minutes for the paint to start peeling off the piece. The drug also dissolves rust from metal and other impurities.
The item is removed and the exfoliated areas are cleaned off with a spatula. If necessary, re-immerse.
The final stage is washing in a sodium triphosphate solution or firing in an oven to remove any remaining toxic methylene chloride.

Examples of special means

Let's look at the most popular and effective removers for removing powder paints.

"Fail-4"

The composition removes paints on any basis, including those based on resins. It also removes primers and putties. Works on surfaces made of metal, concrete, wood, stone, plastic. "Fail-4" is a liquid with high thixotropic properties. The remover can be diluted with isopropyl alcohol by 10-20%.

Apply in 2 ways:

application to surface;
immersion in a container - the liquid level is 1-2 centimeters above the product being processed.

Delaminations are removed with a brush, scraper, or high-pressure apparatus. Exposure time is from 3 minutes to 2.5 hours. Consumption – 150-250 grams per square meter of area. After dissolving the coating, the remaining substances are removed with water and special cleaning agents.

"Remover"

Liquid solution for removing paintwork by immersion. “Remover” is poured into a container made of inert material, and the product is kept for 10-40 minutes. The drug is suitable for reusable use. Before reuse, remove sediment from the container (with a separator or by filtration) and add a new portion of the solution.

To speed up the effect, “Remover” can be heated. The drug dissolves polyester and epoxy dyes and is suitable for metal processing.

Docker S8

Professional powder paint remover. Has a high speed of impact - 3-10 minutes. Odorless gel, used for outdoor and indoor use. Can be applied to the surface and completely immerse the product. After use, wash off any residue with water or detergents. Consumption – 1 kilogram per 5 square meters.

How to remove paint?

Removal of a worn out or outdated protective and decorative layer can be carried out in various ways, during which certain materials and tools will be used. The following options are considered the most popular and effective:

Use of available heating devices. Thermal exposure allows you to quickly remove the old composition, but can have a negative effect on the surface. For work, use a hair dryer, blowtorch or gas burner. If necessary, parts can be immersed in a furnace or fire.

Removing paint using heat is a labor-intensive process, the speed of work depends on the heating device and the thickness of the metal layer: the thicker, the longer it takes to clean

Use of devices with abrasive attachments. The mechanical method allows you to clean metal parts systematically, adjusting the load on the surface. This method is not always suitable for working with small or relief elements. The process will take a lot of time, but may be the only correct solution. Among the devices used are sandpaper, a grinding and polishing machine, a grinder and brush attachments.
You can wash the metal base with your own hands using acetone and white spirit. But if the resulting film has good adhesion to the base, then this will not help. This option is an excellent addition to the previous method.
Quick results are achieved by using a special remover. The chemical method is good because it allows you to remove paint in a short period of time, and even difficult areas can be cleaned.

If the surface has been repeatedly coated with paint, then several approaches to applying the remover will be required.

The use of any tool or material must be done with caution; harm can be caused not only to the metal, but also to health

Water jet disposal method

This paint removal method requires special equipment, electricity, and a source of water. Many people consider the water jet method to be the most convenient, since aggressive and dangerous substances are not used.

Removal with water

Removing the old coating using this method uses a high-pressure unit, which creates high water pressure. For better cleaning, fine glass chips are added to the water, which removes the powder paint. The water for this method must be cold as it cools the coating and makes it brittle, after which it is effectively removed by the abrasive glass particles.

This option is the fastest, simplest and safest - the removal process does not take much time, the metal itself is not deformed and does not cause harm to health. However, you should not remove the paint yourself using this method - for this it is better to contact special organizations.

Sandblasting method of disposal

A sandblaster removes powder paint from surfaces using the pressure of water mixed with sand. Sandblasting is an expensive type of equipment; experience and knowledge are required to operate the unit.

The area of impact of the jet is small (10-12 square centimeters), so cleaning a large surface will require a lot of time and effort. The nozzles of the device are adjustable; sandblasting can be used to remove paint from objects of complex configuration. The pressure of the jet removes pockets of rust and creates slight roughness, which will enhance adhesion during new painting.

Thermal method

Another way to remove powder paint is open fire, firing. At high temperatures, the coating cracks, lags behind the base, and turns into husk. It is removed with a spatula.

Features of the thermal method:

high temperatures are dangerous for some materials - cast iron, plastic;
when heated, the paint releases dangerous substances that can cause poisoning;
Some types of paint may burn, making the job more dangerous.

For burning, use a blowtorch, a hair dryer, or an acetylene-oxygen torch.

Help: the thermal method is used if other methods have proven ineffective.

Liquid chemical solvents

For this method of removing powder paint, the item to be cleaned is placed in a special steel container or stainless steel bath, previously filled with liquid solvent. After some time, the powder coating begins to delaminate, but the metal remains unchanged. To obtain a quick chemical reaction, the part must be stirred periodically in the solution. After this process, the metal is cleaned of the old coating using spatulas and washed with water to completely remove any remaining solvent.

This wash is suitable for cleaning sharp parts that can easily be immersed in the prepared container. In addition to removing the old layer of paint, this product destroys rust and limescale deposits.

Features of removal from different surfaces

Powder paints have increased adhesive characteristics; only special removers can be used to remove them. Solvents (white spirit, turpentine) will not cope with the task. When choosing a preparation, the type of material from which the color is removed is also taken into account.

Aluminum

To remove paint from aluminum (in particular, from car wheels), it is convenient to use removers. The paint layer is removed by applying gel-like products or by immersing the part in a container with the preparation. The following tools are suitable:

"Fail-2", "Fail-4";
Docker S;
"Remover".

Metal

To remove paint from metal surfaces, removers (gels and liquids), sandblasting and waterjet methods are used. Chemical solvents (washes) contain special corrosion inhibitors and remove pockets of rust from products and surfaces. Most popular removers are suitable for metal.

Note that the firing method is not used for cast iron and brass. Do not use the thermal method for sheet and galvanized iron. The sheets become deformed and scale appears on them. The products will require sanding in the future.

Small metal products can be immersed in a container with a remover; for vertical surfaces it is convenient to use a gel.
