Stainless steel is a popular material that is used to produce many products. It has a pleasant color, and most often goes on sale unpainted, because its coating does not lose its attractiveness for many years. However, when you need to create a unified interior design, painting stainless steel may be necessary. Any paint and varnish product is not suitable for this purpose. We will tell you more about how to paint stainless steel with your own hands below.
How difficult is it to apply paint?
Many beginners wonder whether it is possible to paint stainless steel? The answer is yes, but the process is not easy, because paint does not adhere well to the surface of this material. Stainless steel does not have the required level of adhesion. However, the task of painting must be solved by proper surface preparation and selection of a suitable paint and varnish material.
Stainless steel, like copper, galvanized steel and aluminum, requires anti-corrosion protection, this is also the reason why painting of stainless steel may be required.
The task of painting must be solved by proper surface preparation and selection of a suitable paint and varnish material.
How and with what to paint stainless steel with your own hands at home | Finishing experts
Gusevsky Andrey Anatolievich
Painting stainless steel is not an easy task. You must first decide what to paint the stainless steel with and then apply a high-quality coating. After all, if you do not follow certain rules, then the coating will quickly peel off.
Today we will tell you how to paint stainless steel without missing anything. Also in the video in this article and photos you can get additional information that will allow you to do everything efficiently and quickly.
Use of paints and varnishes
Painting stainless steel is a process where the key role is played by a carefully prepared surface, and not by the stainless steel paint itself. So when doing the work with your own hands, you must adhere to certain rules; instructions for this are outlined below.
Attention: If the surface that was prepared was not cleaned very thoroughly and there are defects, then such paint on stainless steel will peel off quite quickly.
So:
- Before painting stainless steel, it must be processed with a conventional grinding machine with a special attachment. Sandpaper is selected with medium grain. The speed is set to maximum. Metal processing using a machine is carried out with smooth movements with little pressure, which will allow you to achieve excellent results and save a lot of time.
- Upon completion of treatment, the surface must be degreased using alkaline compounds or special acids. One of the most effective and cheapest ways to degrease is to use a four percent solution of water and soda.
- To paint stainless steel, it is possible to use regular automotive paint with a hardener. Although its price is steep, it is best suited for this purpose. Do not forget that hardeners are added in large quantities, which will allow the paint to set and dry faster.
- Paint is applied to the surface using a spray gun (see Selecting a spray gun for painting). The use of a paint roller and brush is strictly unacceptable. If stainless steel is painted with one coat of paint, this can cause the coating to quickly peel off the surface.
- Stainless steel paint is never applied in one layer. There must be at least two of them. To enhance the effect, the paint is coated with varnish, this will protect the surface from mechanical damage.
Mandatory conditions that must be adhered to when painting metals susceptible to corrosion:
- Stainless steel paint should never be applied in high humidity. Air humidity should not exceed eighty percent.
- The operating temperature can be from +50C to 350C.
- The surface to be painted must be absolutely dry and free of grease.
Rules for painting with powder paint
If you showed interest in advance and turned to specialists, then you were probably advised to use powder paint.
The secret of the paint coating method is that the paint is applied using a spray gun (see How powder painting is done).
Next, the coating is subjected to heat treatment in a special chamber at a temperature of two thousand degrees Celsius.
Subsequently, a film is obtained that protects the surface from:
- Thermal exposure;
- Mechanical damage;
- Exposure to aggressive chemical environments;
- Impact of corrosion.
Attention: In addition to the listed advantages, powder coating has another advantage: it is a unique decorative pattern. Powder paint lays on the surface in an even layer, but the addition of various additives allows you to diversify both texture and color schemes.
When using powder paint you can get the following effects:
- Marble covering;
- Silver plated;
- Flat or volumetric coating;
- Glossy finish;
- Matte finish;
- Gold plated.
Attention: A paint has appeared on the modern market that imitates a stainless steel coating. Thus, the paint can be applied to a variety of surfaces.
As an example, give a painted stainless steel surface the look of wood, or give a wooden surface the look of stainless steel.
The advantages of this coating include:
- One coat is sufficient when using powder paint;
- Waste-free production when using this type of paint. Unused paint can be collected and used again;
- The durability of the paint is determined by its good adhesion.
- There is no need to wait for the paint to dry, minimal time spent during work.
Painting technology
Stages of powder painting technology:
- Before painting stainless steel, it must be subjected to degreasing and dirt removal treatment.
- Apply a special composition that will create an inert phosphate film.
- Drying the surface.
- Painting the surface in a special chamber. The camera serves to catch the coloring powder.
- Heat treatment of the painted surface in a special oven (see Making a oven for powder painting with your own hands).
Attention: The only drawback is that without expensive equipment, painting the surface yourself is impossible.
Painting with liquid paints
At home, it is possible to treat stainless steel with liquid paints. The same paint is used that is used to paint ordinary steel. The only difference is in the surface preparation methods.
Surface preparation
In order to achieve long-lasting use of the coating, preparation should be approached carefully.
We degrease the surface
Before painting, the following steps must be taken:
- The first priority is surface treatment. To do this, use sandpaper. The ideal option is to use a grinding machine.
- Sandpaper with a medium grain size is placed on a special attachment. If the machine has a speed control mechanism, it is set to maximum. Metal processing using a machine is carried out with smooth movements and with little pressure, which will achieve an excellent effect and save a lot of time.
- Upon completion of pre-treatment, it is recommended to degrease the surface using specially selected alkaline compounds or acid.
- One of the most effective and cheapest ways to degrease a surface is to use a four percent solution of water and soda.
Attention: The optimal solution would be to add a special hardener to car paint to speed up its drying.
Applying paint
Paint for stainless steel is applied using a special sprayer. The use of a paint roller and brush is strictly unacceptable. If stainless steel is painted with one coat of paint, this can cause the coating to quickly peel off the surface. Therefore, there should be at least two layers.
Please also note:
- Air humidity should not exceed eighty percent.
- The operating temperature can be from +50C to 35C.
We do everything as follows:
- Stainless steel can only be painted with a fully mixed solution. After this, the spray tank is filled;
- Apply paint to the surface. When painting, you must follow the rules. The spray gun must be held at an angle of ninety degrees relative to the surface, and at a distance of fifteen to twenty centimeters.
- The spray gun moves relative to the surface in a straight line. When moving the “torch”, it should cover the area already exposed to staining by fifty percent.
- At least two layers of paint are applied to stainless steel prepared for painting; if this is not done, the paint will peel off in the near future. After the first layer has dried, you need to apply another one. In rare cases, it is possible to apply a third layer.
- To protect the surface from mechanical damage and give it improved properties, it can be coated with a layer of varnish.
Attention: Application of paints and varnishes is carried out only on a dry and grease-free surface.
You know how to paint stainless steel and choose the right composition. The most important thing is to properly and efficiently prepare the surface, because this will guarantee the durability of the coating.
Preparatory stage
Before painting stainless steel, it is imperative to thoroughly prepare the product. The final result will depend on the quality of its implementation. Work stages include:
- They start by examining the condition of the selected item; if there are no major defects, there is no need to carry out additional alignment. Due to poor adhesion of an even and smooth base with dyes, which will affect the quality of painting;
- The base is sanded, this will help improve the adhesion of the surface. For small items, use a wire brush to create a rough and matte base. Large areas will be easier to work with a medium-grit sanding attachment;
- Proceed to degreasing the base. The use of acid or alkaline based products is suitable for this purpose. For example, when using an ammonia product, care must be taken to protect the respiratory tract. The master must put on a respirator; good ventilation is created in the room. If you don't have it at home, you can prepare a 4% soda solution.
The base must be completely dry before painting with enamel.
For degreasing, acid or alkaline based products are suitable.
How to paint stainless steel material
Many objects around us are made of stainless steel. Rarely are they covered with paint. Its surface shines and does not fade over time.
Therefore, the conclusion suggests itself that stainless steel is coated with dye only for design reasons. Before you paint stainless steel, you need to decide on a color choice so that it is preferable to your interior design.
How difficult is it to apply paint?
Stainless steel interior items have a smooth surface. If you apply paint on them in the usual way, then nothing will work. Metal has poor adhesion. The correct choice of coloring material and preparation of the steel surface will be the key to high-quality application of the dye - this is the answer to the question of whether it is possible to paint stainless steel.
Applying dye to stainless steel, copper, aluminum, and galvanized metal should also be done to prevent corrosion on their surface. Although rust appears to a lesser extent. The conclusion suggests itself: such metals also need protection and painting.
Preparatory stage
A properly prepared surface of the material guarantees high-quality painting of stainless steel. All actions are divided into several stages:
- The top layer of the steel object is inspected for irregularities. If the defects are not large, then it is better to leave everything without corrections. Because the dye does not spread evenly onto the surface. The quality of work is not maintained.
- To improve the adhesion of paint to metal material, the surface is made rough. If wooden products are polished before painting, then it is better to make stainless steel rough and matte. If the treatment area is small, then the roughness is done with a wire brush. A large area is processed with a sanding attachment. An abrasive disc is used for processing. Medium grit is selected. The machine operates at high speed. No forceful efforts are made. This step is important for polished steel to a high shine.
- It is not recommended to work in a dusty place to prevent dirt from settling on the stainless steel. Remaining dirt after roughening the steel is removed with a wet cloth. The entire area is wiped with special care.
- Degreasing is necessary to eliminate grease stains that reduce the adhesion of paint to the surface. Treatment is carried out with acid, alkaline and ammonia compounds. It is recommended to ventilate the room during degreasing and wear a respirator. The easiest way is to use a 4% soda solution. 4 grams of soda are added to 96 ml of water, resulting in 100 ml of degreasing solution. Painting begins after the steel has dried.
Powder composition for coloring
In everyday life, this method of applying paint on stainless steel cannot be used. The heat-resistant powder composition is applied with a spray gun. After its application, the stainless steel is placed in a chamber where the temperature is raised to 200°C. A film is formed that is resistant to external influences.
The film can be glossy, matte or imitate different surfaces. The applied layer will be even. The result will be a large selection of color shades. Only removable items can be painted in this way. The bulky product is not painted with powder material at the installation site. The new coating is not afraid of direct sunlight.
The process is called waste-free. The material dries in 30 minutes.
The technological process itself has advantages:
- Economical consumption of dye, since it is applied in one layer.
- High adhesion is especially important for stainless steel.
- The remaining powder is not thrown away, but used for the next time.
- Painting is done quickly.
In everyday life, painting is also not carried out after which an oxide film is formed. Steel is processed using plasma at a low temperature. The process requires certain conditions to be met: the presence of oxygen in the atmosphere. Although the metal remains unchanged (matte and shiny), covered with an oxide film, it changes color.
Liquid composition for coloring
Automotive paint is used to apply the coloring material yourself. To increase tenacity with stainless steel, it is recommended to add hardeners.
Factory-produced stainless steel paint is available for sale and is already suitable for application to stainless steel. It is recommended to purchase it in tandem with a primer. This increases the adhesion of paints and steel. Most often the coating is black.
Recommendations for work
- The temperature is maintained at 5-35 degrees; humidity no more than 80%.
- You cannot use ordinary tools (brush, roller) when painting. The work uses a spray gun. Hand movements go in a straight line, each subsequent strip of paint partially overlaps the previous one. The dye is sprayed quickly so that it hardens evenly. The tool is located at a distance of 20 cm from the surface and at a right angle.
- Before starting to paint stainless steel, the paintwork material is thoroughly mixed until smooth. After this, the spray bottle is charged with liquid composition.
- Apply 2 layers of paint. Before painting the stainless steel with a second layer, you need to wait until the first layer has dried.
- To enhance resistance to external influences, the painted surface is coated with transparent yacht varnish.
Important : the paint coating will last a long time if the top layer of steel is cleaned without defects. Otherwise the coating will come off.

Selection of material for painting steel
The possibility of using oil paint for metal or a wax composition for metal for painting is not excluded. You can make decorative inscriptions with regular nail polish.
In practice, the use of patina is common. This changes the shade of the steel or its surface. The process is completed by applying wax.
conclusions
If you wish, you can choose how to paint even a metal such as stainless steel. Liquid paint is used at home. It is also found in the form of aerosols.
In industrial conditions, a powder composition is applied. The new layer protects the steel from corrosion. If fillers are added to the dyes, the texture of the metal changes.
Although experts still advise leaving it in its natural state.
Powder composition for coloring
Under domestic conditions, this method is difficult to implement. Heat-resistant powder type paint for stainless steel is distributed over the surface using a spray gun. After this, the item is placed in a room where high-temperature exposure up to +200 degrees is provided.
As a result, I get a durable film that is resistant to environmental influences; the item can be used outdoors for a long time without losing its properties. It is possible to obtain a matte or glossy finish; there is a variety of colors: gold, black, white, bronze and others can be chosen for painting. The paint lays down in an even layer. The coating has wear-resistant properties.
However, this technique is only suitable for painting removable elements; large objects cannot be painted with powder products. The drying process takes about half an hour.
Professionals highlight the following positive aspects of the technique:
- Economical paint consumption on stainless steel;
- High level of adhesion;
- Waste-free dyeing;
- The process is carried out at a fast pace.

Paint composition for stainless steel: features of powder coatings and painting nuances
› Paint › Working with paint ›
Stainless steel, despite its properties, requires protective treatment. Applying paint to a stainless steel surface is associated with certain difficulties. The article will discuss how and with what to paint stainless steel; the advantages of powder paint and the subtleties of the painting process itself will be revealed.
Features of stainless steel
Corrosion-resistant steel is a widely used material. The variety of physical properties of stainless steel is explained by the addition of various impurities during its production. The characteristics of the material are affected by the amount and type of additives.
Therefore, among the brands there are alloys that over time (with prolonged use in an aggressive environment) lose their anti-corrosion properties. For this reason, a problem arises regarding methods of protection, and painting becomes a solution.
To understand how to paint stainless steel, you need to find out what properties this material has. Features of stainless steel in comparison with other metals and alloys:
- Increased strength. Due to its strength, steel copes with significant physical loads without losing its characteristics (primarily its shape).
- Impact resistance. Changes in operating conditions and aggressive environments do not lead to loss of properties, which increases the service life of stainless steel structures.
- High temperature resistance. Due to its heat resistance, steel does not lose its shape, does not change dimensions and retains its properties at high temperatures.
- Environmentally friendly. Minimized oxidation processes reduce the level of harmful effects on the environment. The absence of harmful impurities contributes to the fact that stainless steel is widely used in the food industry.
- Corrosion resistance. A number of alloys are not susceptible to rust even when exposed to alkali and acid.
- View. Stainless steel is clean, shiny and retains these properties for a long time.
Pay attention to: How to dye a down jacket at home
The specific grade of steel is selected taking into account the purpose of use. The abundance of additives makes it possible to obtain the necessary alloys. In some cases, additional processing is required, for example, painting stainless steel. The characteristics of the material being painted make it appropriate to use powder coatings.
What is powder paint
Powder coatings are mixtures of solid particles, consisting of many components. The basis is a powder-type polymer and a coloring pigment. Depending on the area of application of the paint, the components of the composition are different. The main additives are:
- fillers (aluminum oxide, titanium dioxide);
- hardeners (for example, epoxy resin);
- resins that create a protective film on the treated surface;
- acrylates.
Stainless steel paint in powder form does not contain solvents, so it is not a flammable or toxic paint composition.
If the technology for painting a polished stainless steel surface is followed, the harmful impact on the environment and humans tends to zero. The advantage of powder paint is its flowability that persists over time; paintwork components do not thicken or stick together.
This property eliminates the need to dilute the paint before use. Flowability also determines the surface treatment technology - the coloring composition is sprayed onto stainless steel.
The paint particles receive a charge, while the workpiece carries the opposite charge. Therefore, the powder sticks to the surface. Subsequently, the adhered particles are subjected to heat treatment in an oven (polymerization).
Difficulties in painting stainless steel
Powder coating of stainless steel is a method that meets the characteristics of the surface being treated. Smooth steel rejects the approach of using conventional liquid paints and varnishes, since the latter simply do not adhere to it. The adhesion of stainless steel is low, which adds to the complexity of painting. The solution to the problem is the choice of an adequate coloring composition and adherence to technology.
At home, painting stainless steel with powder is difficult. Additional equipment will be required, namely an installation for imparting a charge to paint particles, a spray gun, and an oven for polymerizing the paint composition. It is commercially available, but if you have the skills and experience, you can make it yourself.
Powder coating is a technology most often used in industrial settings.
Preparatory stage
Powder paint for stainless steel should be applied to the prepared surface. The preliminary stage involves the following:
- Inspection of processed parts to identify defects (scratches, chips). Shallow imperfections on a smooth stainless steel surface can be preserved to improve adhesion.
- Making the material being painted rough. If we are talking about small parts, then a metal brush is suitable for processing. In other cases, it is better to use a grinder with an appropriate attachment. A medium-grit abrasive disc will do.
- Cleaning the part from processing products. A wet cloth is suitable for removal. The part must be thoroughly wiped.
- Degreasing. Grease stains on stainless steel will impair paint adhesion, so alkaline or acidic compounds are used. When degreasing with such compounds, it is necessary to observe safety precautions (ventilate the room, wear gloves and a respirator). At home, you can degrease the part using a soda solution (4 grams of soda per 100 ml of water).
- Drying the part before painting.
Personal protective equipment is required during the preparatory stage and during painting.
Cleaning and degreasing the surface
Painting process
In industrial conditions, before painting, the parts being processed are washed in chambers and dried in ovens; a conveyor process is organized there. At home, prepared stainless steel can be dried on a table or on a radiator. The powder is applied by spraying from a gun. The equipment is made in such a way that the paint particles receive one charge, and the part being painted receives the opposite charge.
Under such conditions, the powder adheres to the stainless steel in an even layer. Industrial painting is carried out quickly, but at home this process will take longer. The technology of applying paint on stainless steel in powder form involves electrostatic or turbostatic spraying.
The first option involves an external charge source, the second method allows particles to be charged by rubbing them against the walls of the turbine.
The second stage of painting is melting the paint in an oven at a temperature of 150-220 degrees. Powder particles melt at high temperatures and form a film on stainless steel, which subsequently hardens.
Industrial polymerization chambers are designed for changing reflow conditions (sudden increase and decrease in temperature, inclusion of recirculation of air flows, etc.).
Do-it-yourself ovens are more primitive, but purchasing industrial equipment for personal (usually single) purposes is impractical.
Powder coating process
Conclusion
When stainless steel parts are powder coated and the technology is followed, their service life increases significantly. The alloy, which is resistant to corrosion, receives additional protection due to paint.
Painting stainless steel with powder paints and varnishes is most often carried out in industrial conditions. This is explained by the fact that equipment is required to apply the composition, as well as for the subsequent melting (polymerization) of paint particles.
You can also paint stainless steel yourself if you first purchase the necessary equipment, or construct it yourself.

If you need to do the painting yourself, use paints intended for cars. To obtain better strength, hardeners should be used.
On the construction market you can find a special product for painting stainless steel. Experts advise applying it after priming the surface. This will improve grip and the result will be better. The paint is usually sold in black.

How to paint stainless steel at home? — Machine tools, welding, metalworking
This type of metal, such as stainless steel, is used to produce a large number of objects around us. Often the latter are unpainted, since they do not need protection from moisture, and at the same time they can effectively shine with their metal surface.
So the coloring here is mainly due to individual design goals.
Therefore, if you, say, want to paint corrugated stainless steel black, this means that this color is necessary as part of the interior design, and it is more preferable than the natural color of the metal.
How to paint stainless steel: different methods and painting tips
28.04.2019
Stainless steel has excellent performance characteristics, which is why this metal is used quite often and is very popular.
Various objects and products are made from stainless steel; their surface can be painted, polished or matte.
It is important to remember that stainless steel has a poor adhesion rate, so many people have the question of how to paint stainless steel so that the paint stays as durable and long as possible?
Powder paint
Although you can paint stainless steel with liquid paint or a composition in an aerosol can, most experts prefer painting with powder paint. This material is applied to the parts using a spray gun.
After the composition is applied, the painted stainless steel must be heated to a temperature of about 200 degrees. Such heating is possible with special equipment - a heating chamber or furnace.
By heating the powder paint to this temperature, the painted layer acquires several important advantages:
- the coating will be resistant to corrosion;
- the film becomes very durable, it is very difficult to remove it from the surface;
- no damage will occur on the painted layer;
- temperature changes and aggressive environments will not negatively affect the coating;
- the painted layer is perfectly smooth;
- You can paint it in any shade by adding special pigment substances.
Unfortunately, in order to paint stainless steel with powder paint yourself, you need to purchase a special oven, which is why this painting method is rarely used at home.
Typically, powder compositions are applied to stainless steel only in enterprises that have special thermal equipment. In addition, only a removable part can be painted with powder paint; it is impossible to paint a structure that is already installed using this method.
Today, this painting method is the most effective, as it creates a durable and strong protective layer.

DIY painting
At home, you can paint stainless steel with liquid paint. They also produce paints and varnishes in the form of aerosols. In order for the paint to last as long as possible, it is important to take the preparatory work seriously. The painting process is very similar to the method of painting regular metal. The first step is to prepare the surface; the following steps are included in the preparation:
- before painting the metal, it must be cleaned with a grinding machine or regular sandpaper;
- after cleaning, the surface is treated with some kind of degreasing agent; you can use ordinary baking soda dissolved in water, or some kind of organic solvent.
Recommendations for work
To simplify the process and get the desired long-lasting and attractive result, you should follow the recommendations below:
- You can work at temperatures from +5 to +35 degrees, humidity should not exceed 80%;
- Applying paint with a brush or roller is not possible; only a spray gun is suitable. They move in straight lines, each new strip is made with a slight overlap with the previous one. You need to work with quick movements to ensure the layer dries evenly. The spray gun should be at a 20-centimeter distance from the product, the angle should be made right;
- The dye must first be stirred and then poured into the spray bottle compartment;
- Application is carried out in two layers, each must dry completely before applying the next one;
- To obtain better resistance to environmental factors, you can coat the surface with yacht varnish or another transparent type.
Good adhesion will be obtained when the surface of the stainless steel is polished without flaws.
Application is carried out in two layers.
How to paint stainless steel
The dyeing workflow is carried out under certain conditions. Separately, it should be noted that stainless steel is painted by the method of forming an oxide film on its surface. This method requires oxygen in the atmosphere. As a result, the painted surface changes color thanks to the oxide film, leaving its original appearance intact. A matte or shiny product will remain that way.
The staining of stainless steel and the resulting color depends on the following factors:
- differences between voltages;
- current density;
- time.
Thanks to this well-known method of electrochemical coloring, it is possible to create a unique color scheme of various colors and shades. Stainless steel also becomes more protected in its properties.
A fairly common method of applying a coloring composition to stainless steel is powder coating. The process of applying such a dye does not take much time. The addition of different pigments produces different colors. Powder coating can produce a matte or glossy surface. But without the help of special equipment, this coloring method cannot be carried out.
To ensure that stainless steel surfaces are painted correctly, you must follow the attached instructions. Painting at home with liquid paint requires compliance with the following rules:
- Before painting, the metal surface is sanded.
- Having completed this treatment, the surface of the stainless steel must be degreased.
- You can paint metal with regular car paint from an aerosol can.
- The composition only needs to be applied in two layers.
By following these rules, you can achieve excellent results when painting various stainless steel products. If you do not follow them, the paint will quickly crumble and all the work and costs of purchasing it will be in vain.
What else can you coat stainless steel with?
It is allowed to use high quality oil paint, wax paints intended for metal objects, and nail polish. Nail polish is suitable when you need to make small details or inscriptions on the surface.
Patina copes with the task; it can completely change the color of the product. Cold or hot technique is used. You can apply wax on top.
It’s convenient when the paint comes in spray cans. Aerosols allow you to evenly distribute the product over the surface; there is no need to purchase a spray bottle. But they are suitable for small parts. The color range of these products is varied, you can choose any shade: from gold to brass.
Aerosols allow you to evenly distribute the product over the surface; there is no need to purchase a spray bottle.
Selection of material for painting steel
When choosing paint and varnish products, you need to carefully study the properties and purpose of the product; these data are prescribed by the manufacturer on the packaging. Paints suitable for working with steel can be used. You should also understand under what conditions the item will be used, whether additional protection from external factors is required, whether chemical resistance is needed, and others.
Paints suitable for working with steel can be used.
Mistakes when painting stainless steel
Non-professionals can make mistakes when painting, they lead to deformation of the layer, this happens for the reasons described below:
- Temperature and humidity indicators in the room where stainless steel is painted are not set to the recommended values;
- Skipping surface priming;
- Adding too much varnish to the dye;
- If the amount of hardener in the paint is too low, then the coating will be brittle and brittle;
- Poor degreasing of the product.
Non-professionals can make mistakes when painting.
Painting Tips
In order to avoid the mistakes described above, you need to know what standards for work must be observed. The result will be of high quality if you follow these tips:
- The temperature can vary from +5 to +35 degrees, the humidity in the room is also important, it should not be higher than 80%;
- They paint not with brushes or a roller, but with a spray bottle or spray can, making even stripes that are applied overlapping;
- The tool should be at a distance of 20 cm from the product, while the surface is painted quickly;
- Several layers are made, after painting each one, wait for the previous one to dry completely;
- It is also preferable to apply varnish on top of the paint; it will improve the glossy effect and create additional protection for the material.
The tool should be at a distance of 20 cm from the product, and the surface will be painted quickly.
It is possible to paint stainless steel, the main thing is to approach the process thoroughly. After all, the material has a poor degree of adhesion; to improve it, a preparatory stage is carried out, which will largely determine what quality of coating will ultimately be obtained. It is also important to choose a suitable paint and varnish; not all materials can be used for this purpose. The article described the options of paints that can be used. Compliance with the rules of work will help to obtain a beautiful and protective coating of stainless steel.

Advantages of protective coating for stainless steel
Powder painting is the undisputed leader among various methods of applying decorative and protective coatings to stainless steel.
Powder painting allows, unlike other methods, to obtain a durable coating that will not only not peel, but will also improve the performance of your stainless steel product.
Powder coating of galvanized and steel pipes is the best way not only to decorate various pipes, but also to protect the product from external factors and extend its service life.
- The technology allows you to get a huge number of colors and shades. Stainless steel, steel or galvanized pipes painted in this way can be glossy or matte and have different textures.
- Uniform application on stainless steel products, including all bends and corners, is another advantage of this technology.
- Powder coating of stainless steel is an opportunity to improve the performance of your product. Such products demonstrate high resistance to physical and chemical influences. The service life of painted stainless steel is significantly increased.
- During the work process, only one layer of paint needs to be applied to stainless steel, which makes the cost of powder painting quite low.
The ability to not only paint, but also manufacture stainless steel products themselves provides a comprehensive approach to solving your problems. By contacting, you receive a full range of services for the manufacture and coating of products.
Stainless steel painting technology
Accurate adherence to the technological stages of powder coating of stainless steel and steel or galvanized pipes is the key to applying high-quality powder coating. The preparatory stage includes mechanical cleaning, degreasing and phosphating of the metal.
Pre-drying is also a mandatory step before the painting process itself. After the painting process, the stainless steel or pipes are placed in a polymerization oven, where the applied coating melts, forming a smooth surface.
Final drying and packaging are the final stages of powder coating of stainless steel, galvanized and steel pipes.
