Top 3 Powder Paint Removers, Best Ways and Tips for Removal

Powder coatings are widely used in the automotive industry, they are used to cover appliances, stock and interior details. Durability, resistance to any impact and strong adhesion to the surface are the main characteristics of such a coating. It is difficult to remove the paint from the products. Let's consider the main methods of removing powder paint from surfaces - chemical stripper, mechanical and thermal methods.

How to remove powder paint with a special remover

To remove powder paints from surfaces, special formulations are produced that contain aggressive solvent substances. This method does not require special equipment, it is one of the simplest and most budgetary.

Products are immersed in a wash or the composition is applied to the surface, wait for softening, peeling of the paint crust, then cleaned with a spatula. The effectiveness of the work depends on the correctly chosen preparation, the thickness of the layer and the duration of the paint.

General rules

How to properly remove a coat of powder paint:

1. Before working with aggressive chemicals, put on personal protective equipment - gloves, glasses, clothing made of durable coarse fabric, a respirator. Work is carried out in a well-ventilated room.
2. Products from which you need to remove paint are washed, degreased, dried well.
3. Gel solvents are applied with a brush, roller or spatula. They do not drip, they adhere firmly even on vertical surfaces. In this way, you can remove paint from floors, roofs, fences from a large area.
4. To clean small objects, use the immersion method. The washing liquid is poured into a container made of stainless steel or other material that is not afraid of acids and alkalis.
5. It usually takes 15-30 minutes for the paint to peel off the product. Also, the drug dissolves metal rust and other impurities.
6. The thing is removed, the exfoliated areas are cleaned with a spatula. Submerge again if necessary.
7. The final step is rinsing in a solution of sodium triphosphate or baking in an oven to remove toxic methylene chloride residue.

The higher the temperature of the stripper, the faster the dissolution takes place. If necessary, the washing is heated to accelerate the reaction.

Examples of special tools

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

Fail-4

The composition removes paints on any medium, including resin-based. Also washes primers and fillers. Works on metal, concrete, wood, stone, plastic surfaces. Fail-4 is a liquid with high thixotropic properties. Wort can be diluted 10-20% with isopropyl alcohol.

Applied in 2 ways:

• superficial application;
• immersion in a container - the liquid level is 1-2 centimeters above the processed product.

Detachments are removed with a brush, scraper, high-pressure device. Exposure time is 3 minutes to 2.5 hours. Consumption - 150-250 grams per square meter of surface. After the coating dissolves, the residues of the substance are removed with water, special cleaning agents.

"Remover"

Liquid solution for removing paints and varnishes by immersion. "Remover" is poured into a container of inert material, the product is kept for 10-40 minutes. The drug is suitable for multiple use. Before reuse, the sediment is removed from the container (by a separator or by filtration) and a new part of the solution is added.

To accelerate the effect, "Remover" can be warmed up. The drug dissolves polyester, epoxy paints, is suitable for processing metals.

Docker s8

Professional powder paint remover. Has a high speed of action - 3-10 minutes. Odorless gel, used for exterior and interior use. Can be surface applied and completely submerged. After use, wash off the residue with water or detergents. Consumption - 1 kilogram per 5 square meters.

Water jet removal method

This disposal method will require special equipment, electricity and a water source. Many people consider the water jet method to be the most convenient, since no aggressive and dangerous substances are used.

Water is supplied under high pressure by a pump and sprayed through the nozzles. The pressure and the shape of the jet are adjusted using a hydraulic gun with nozzles.Powerful pressure of water, to which an abrasive (glass crumbs) is added, destroys the layer of paint, spills the exfoliated pieces and helps to wash it off the surface.

Water jet cleaning is suitable for large flat surfaces; small objects and objects of complex configuration cannot be removed from the painting using this method. If ferrous surfaces are treated, corrosion inhibitors are used in the final stage. To make the paint more brittle and to facilitate chipping, cold water is taken.

Sandblasting removal method

A sandblaster knocks powder paint off surfaces by the pressure of water mixed with sand. Sandblasting is an expensive type of equipment; experience and knowledge are required to work with the unit.

The impact area of ​​the jet is small (10-12 square centimeters), so it will take a lot of time and effort to clean a large area. The nozzles of the device are adjustable, sandblasting can be used to remove paint from objects of complex configuration. The pressure of the jet eliminates rust spots, creates small roughnesses which, when repainted, will increase adhesion.

Thermal method

Another way to remove powder paint is by open fire, cooking. At high temperatures, the coating cracks, drags behind the base, turns into an envelope. It comes off with a spatula.

Characteristics of the thermal method:

• high temperatures are dangerous for some materials - cast iron, plastic;
• when heated, the paint emits dangerous substances that can be poisoned;
• some types of paints can burn, increasing the risk of work.

For burnout, a blowtorch, a building hair dryer, an acetylene-oxygen torch are used.

Note: The thermal method is used if other methods are ineffective.

Peculiarities of removal from different surfaces

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

Aluminum

It is convenient to use strippers to remove paint from aluminum (especially car rims). The layer of paint and varnish is removed by applying gel-like agents or immersing the part in a container with the drug. The following tools will work:

• Fail-2, Fail-4;
• Dockers ;
• "Remover".

These preparations wash out powder dyes with different bases:

• polyester;
• polyurethane;
• epoxy;
• epoxy polyester;
• polyacrylate.

For aluminum surfaces, you can use other types of paint stripping - water and sandblasting, baking.

Metal

To remove paint from metal surfaces, strippers (gels and liquids), sandblasting and water jet methods are used. Chemical solvents (washes) contain special corrosion inhibitors, remove rust stains from products and surfaces. The most common washes are suitable for metal.

Note that the firing method is not used for cast iron and brass. Do not use thermal method for sheet metal and galvanized iron. The sheets are deformed, dirt appears on them. In the future, the products will have to be ground.

Small metal objects can be immersed in a container with a wash, for vertical surfaces it is convenient to use a gel.

Additional tips and tricks

It may take 2-8 hours to clean the paint surface, this work is difficult and dangerous. Some additional tips:

1. If possible, it is best to use mechanical stripping techniques as they are the safest.
2. Washes should be used with good room ventilation; be sure to use long gloves and coveralls. When removing the dissolved coating with a wire brush, mesh or spatula, the spatter will fly in all directions, it is easy to burn yourself with a chemical.
3. Chemical solvents are resistant to old coatings (no more than 2-3 years from the moment of painting). If it is painted earlier, it is better to choose a different method.
4. When using cold weather washing in unheated rooms or outdoors, the composition is preheated.

If the products have a complex configuration (for example, when removing paint from an aircraft), all the holes are carefully sealed so that chemicals do not get inside.

When updating painted products, preliminary removal of the old coating is required. Powder coatings can be dissolved using washings, mechanical methods and baking. The work requires time and effort, as well as strict compliance with safety measures.
