How to paint a metal stove in a bathhouse

What properties should paint for stoves have?

The metal walls of the furnace become very hot when a fire burns inside it, and when heated, the metal expands. In addition to extremely high temperatures, other factors also have a destructive effect on it. These include water vapor, splashes of cold and hot water, and low temperatures. After all, a sauna stove is used periodically, and in winter frosts the metal cools down to sub-zero temperatures. It happens that during one day the metal heats up and cools down several times.

All this leads to the fact that the surface unprotected from the external environment rusts, the walls of the furnace gradually become thinner, burn out and it becomes unusable.

Metal working in such difficult conditions requires reliable protection in the form of a paint coating that can withstand all harmful factors. Therefore, the question of how to paint an iron stove in a bathhouse is far from idle. The coating for it must have the following characteristics:

• heat resistance of at least 500-600 degrees;
• elasticity, the ability to expand without cracking;
• waterproof to prevent metal from coming into contact with water and water vapor;
• anti-corrosion properties.

Another important requirement concerns the protection not of the metal, but of the people in the bathhouse. If the paint contains toxic substances that are released into the air when heated, then the harm from bath procedures will be more than good. This means that special attention should be paid not only to its composition, but also to the presence of a safety certificate.

Advice! The darker the coating, the higher the heat transfer of the iron stove. Therefore, as a non-mandatory requirement, but a recommendation on how to paint an iron stove, we can advise using paint in black, brown, bronze, gray and other dark shades.

Conclusion

Coloring is a simple procedure. It usually lasts several days due to the need to apply 2-3 layers, between which it is better to wait at least a day so that the material dries well.

It is important to use high-quality materials and tools - this will be reflected in the result. The main thing is to wait until each layer dries, clean the surfaces well, and work with gloves.

For painting, enamel paints that are resistant to high temperatures, lime, and varnish can be used. When choosing, proceed from the desired effect and cost of the material.

Heat-resistant paints and enamels for baths and saunas

The choice of coatings for metal stoves is not very large. Only varnishes, enamels and paints based on polyurethane or silicone have high heat resistance and other necessary properties.

• Compositions based on polyurethane resins can withstand a maximum temperature of no more than 600 degrees, and with strong heating they change color unpredictably.

• Silicone enamels, made without the use of toxic components and withstanding higher temperatures, are more reliable and durable.

What to consider when purchasing

The characteristics of heat-resistant paint of different colors, even of the same brand and the same manufacturer, may differ. The base is the same, but the pigments used to impart color are different. They affect the properties of the compositions, and primarily their covering power and resistance to high temperatures. Therefore, before painting an iron stove in a bathhouse, so that it does not rust and remains in working condition for a long time, find out to what maximum temperature it heats up.

The most heat-resistant enamels are gray and silver. They add aluminum powder, which has a scaly structure and protects metals well from corrosion.

They are followed by compositions in black and all shades of brown, red, and green.

The best brands

When choosing what to paint a metal stove in a bathhouse with, you can consider products from both foreign and domestic manufacturers. Moreover, our enamels are in no way inferior to imported ones in terms of heat resistance, hiding power, durability and durability. But these brands are deservedly considered leaders:

• Certa;
• Elcon;
• Kudo;
• Dali.

In addition to heat-resistant enamels, Cetra also offers patination compounds with the same properties, which can be used to decorate stoves and fireplaces, giving them an exclusive look.

Painting process

After completing the preparatory work, we proceed to painting, step by step following the instructions on the package.

We carry out painting following the technology and sequence of work:

1. Mix the paint thoroughly with a plastic or wooden spatula. If necessary, add a solvent suitable for the selected material. The composition should not contain foreign impurities.
2. When using a spray gun, prepare a more liquid composition by pouring it into the sprayer through a paint sieve. This will prevent small debris from entering and clogging the tool nozzle.
3. Before painting a newly welded stove, it should be heated in order to “burn out” debris and lubricant residues from pores, microcracks and cavities.
4. Apply paint starting from the edge of the stove or inconvenient and hard-to-reach places.
   Then we cover the entire surface with an even layer, avoiding smudges and unpainted areas. The number of coating layers depends on the selected compositions and requirements for the type and quality of painting. It should be borne in mind that too thick a layer reduces heat transfer from the firebox and may peel off.
5. Leave the structure until completely dry.

Some coatings are applied only to surfaces heated to the required temperatures.

When chemically processing metal by bluing, the surfaces are coated with a mixture of phosphoric acid, butyl alcohol and water.

After the mixture has completely dried, the metal is washed with water and laundry soap, heated to 150°C, and treated with a spray gun with a solution of caustic soda (sodium hydroxide). Blueing gives the metal a dark shade without the use of dyes.

Paint selection

Maintaining a marketable appearance is the main goal of the home owner, who noticed that the potbelly stove was slightly deteriorated in appearance. If chips or scratches appear on its surface, it’s time to renew the coating.

Paint selection

Coloring should be repeated every 5-7 years. If the pigment layer is damaged earlier, this indicates low quality of the product used last time or errors on the part of the performer. Also, cracked old paint does not protect the surface of the stove well, so updating it also plays a protective role, not just an aesthetic one.

A potbelly stove is one of the most popular heating units. Such stoves are installed in many country and country houses. Over time, the stove loses its original appearance, and there is a need to restore its aesthetic characteristics.

It is recommended to apply the solution to the potbelly stove in a thin layer.

A potbelly stove can be painted using different finishing materials. Choose the option that suits you best according to your personal preferences and available budget.

Heating stovesWhat is the best way to paint a potbelly stove?

18.11.2015

The stove, known to many as a potbelly stove, is one of the most popular heating devices. Designs of this kind are found in many private homes.

But the peculiarity of a potbelly stove, as well as any other stove, is that over time it loses its original appearance and there is a need for painting in order to restore its former aesthetic qualities.

Therefore, today we will talk about how to paint a potbelly stove: what materials can be used, how to carry out this procedure in general.

The technique of applying the coloring composition and the direct selection of products for the work are important points that it is recommended to pay special attention to.

It became popular at the beginning of the twentieth century, when people were going through difficult times of revolutions and wars.

Since everyday life was almost completely destroyed, it was she who saved the frozen walls of apartments and houses. The costs of its manufacture are minimal, and the design is not so complicated.

Unfortunately, prolonged use of the stove leads to the loss of its former appearance. In order to restore its beauty, you will need various finishing materials and the desire to create.

The choice of finishing materials will directly depend on the imagination and interior of the house, as well as on the basis of the financial situation. It is also worth considering the material on which the potbelly stove is made.

For example, for a brick stove, lime is ideal; for a metal stove, the paint must be heat-resistant.

If you don’t want to bother with the coloring process, then you can use heat-resistant varnish with silver, bronzing with drier or liquid glass.

Note: Please ensure that the paint does not emit toxic fumes during use!

A potbelly stove is not always finished with brick or anything else.

In such a situation, it will need to be updated frequently so that its appearance does not upset the eye. For such a task, ordinary paint will not be suitable, since the potbelly stove heats up to very high temperatures during operation.

Naturally, ordinary paint cannot withstand such heat. Heat-resistant paints are ideal for the renovation process. It should be taken into account that such paint should be made on the basis of silicon and silicone.

And only thanks to this condition the stove will be able to maintain a neat appearance for a long time.

Potbelly stove painted with heat-resistant paint

Thanks to heat-resistant enamel, you can achieve the following:

• Surface preservation;
• Moisture resistance;
• Pollution protection;
• No rust or oxidation process.

There are special enamels in cans or cans (sprays).

Tip: Remember! In addition to all of the above, heat-resistant paint will add aesthetics and brightness to the potbelly stove!

Potbelly stove in a modern interior

To paint a metal surface you will need to acquire:

• Container for preparing the solution;
• Drying oil;
• Egg white;
• Milk;
• Enamel solvent;
• Red brick;
• Paint;
• With brushes.

The preparation process begins with cleaning the working surface, that is, you need to remove all dirt, remove uneven surfaces, and seal cracks. Then you can start the process.

Important: Please note that ordinary putty will not work for this procedure!

To prepare such a mixture with your own hands, you need to crush one red brick with a hammer. The consistency must be similar to “flour”. The result is poured into a container, 10 chicken proteins are added and beaten.

The thick mixture is capable of qualitatively eliminating all imperfections in the furnace surface. For this procedure you will need a hard brush.

This stage must be treated with special attention, since the outcome of all work depends on the result obtained!

Before painting, the surface must be thoroughly cleaned

Once you are sure that the putty has dried, proceed to the next step. Now you need to treat the entire surface with drying oil (oil).

Thanks to this, you can significantly save on enamel and also improve the quality of its application.

Considering that some of the material will simply be absorbed into the surface, the layer of such oil should be quite thick.

Like all previous processes, this stage of the “marafet” must also be done responsibly and with love.

It is worth paying attention to the fact that the heat-resistant enamel is not too thick. If the composition is too viscous, there is a risk that the surface will not absorb the paint enough, and it will simply be impossible to work with such material. It is highly recommended to dilute it.

A solvent designed for organic materials will help in this matter.

The required thickness is ready and now you can begin the actual process of painting the stove. It is very important that the first coat of paint is thin. After it has completely dried, the next layer is applied.

An indicator that the layer has laid evenly will be indicated by the absence of gaps, that is, the surface of the potbelly stove will not be visible in certain places.

In case of defects, you need to apply a control layer, through which the bricks should definitely not be visible. Now you can paint all the cast iron elements.

It happens that there is no suitable paint in the store, and there is simply no time to look for something more or less suitable. In this case, you can prepare it at home.

This process requires turpentine and PF-283 varnish, which must be mixed in a one-to-one ratio. The mixture must be thoroughly stirred. A properly prepared mixture will be transparent and matte. Now, as for the desired color.

To do this, the gouache (its color should match your preferences) must be thoroughly dried in order to then make a powder from it. The result obtained is added to the mixture and the desired paint color is ready. You can safely begin the process.

How to coat

In order for enamel or paint to stick well and for a long time on the metal surface of the stove, it is not enough to choose the appropriate composition. It is necessary to strictly adhere to the technology when applying it. All the necessary information is on the packaging, but the principle is the same for any product.

Surface cleaning

Dust, dirt, rust, old coating and any other layers will not allow the paint to adhere well to the surface and adhere to it. They need to be removed.

• First, they use a metal brush to remove obvious contaminants and loose rust.
• Then the surface is brought to a shine with a drill with abrasive attachments or sandpaper.

For reference! If the instructions allow, instead of a mechanical cleaning method, you can use a chemical one by applying a rust converter to the surface.

• The next step is to remove dust using a soft broom or vacuum cleaner and damp wiping.
• The dried metal is degreased using a solvent recommended by the manufacturer. If there is no such recommendation, you can use white spirit or solvent P 646.

How and under what conditions to dry

The drying time and conditions are indicated by the manufacturer on the product packaging. Drying of painted oven structures should take place in a dry room at a temperature of 15-45°C. Some paints only dry when heated, so you must strictly follow the manufacturer's recommendations.

It is important to protect painted surfaces from drafts, dust and debris.

The stove should be heated no earlier than 70-90 hours after completion of work. When working with chemical dyes, do not forget to protect your hands, eyes and respiratory tract. Wear a carbon filter respirator, goggles, gloves and protective clothing.

Briefly about the main thing

If you are deciding what paint to paint an iron sauna stove, then you need to choose compounds that are resistant to high and low temperatures and high air humidity. And also those that will not release toxic substances during bath procedures. Silicone enamels best meet these requirements. They cost more than other heat-resistant paints, but they also last longer. However, the service life directly depends on the quality of surface preparation and adherence to coating technology.

Lime painting: preparatory stage

Rice.
1. Potbelly stove made of metal. A potbelly stove can be made of metal. This design is shown in Fig. 1. The oven can also be made of brick. Stoves can be painted using different finishing materials. Thus, for finishing brick structures, an affordable and fairly high-quality material called lime is often used. To paint a potbelly stove yourself, prepare the following required materials, fixtures and tools:

• Brushes and rollers;
• Bucket;
• Solvent (can be replaced with alcohol);
• Enamel in aerosol;
• Lime;
• Water;
• Dyes;
• Glue.

Construction of a potbelly stove made of metal.

Before painting the potbelly stove, you need to prepare a solution suitable for this. Take a bucket or other container, add lime and fill it with the same amount of water. After this, mix the mixture thoroughly and add animal glue to it. You can purchase this glue at a store that specializes in selling various painting supplies.

To understand whether a lime-based solution is ready, you need to do the following: take a small piece of glass, fix it vertically and apply a little solution. If the paint spreads no more than 3 cm, then everything was done correctly, you can begin finishing the stove.

If you want to paint your potbelly stove not white, but some other color, then you will need to add a little dye to the solution. Potassium permanganate, blue or synthetic paints can be used as a dye. The specific option is selected depending on what shade you want to get.

Before painting a potbelly stove, its surface must be thoroughly cleaned of dust and dirt. Cracked plaster needs to be cleaned. With this kind of preparation you can achieve the perfect result. The surface will be painted with the highest quality, and the result will please the eye for a long time.

Lime is applied to the surface in 2 layers. For work, you can use a whitewash brush or a roller with medium-length bristles.

Rice. 2. Tribo charging circuit.

To avoid streaking, add a small amount of salt to the lime before starting work. During the painting process, move the brush exclusively horizontally or vertically.

After applying the first layer, leave the oven for a while to allow the solution to dry completely. After this, you will need to paint the potbelly stove a second time in the same way. The second layer should be made thinner than the first.

After you have completely covered the potbelly stove with lime solution, you can safely proceed to a new stage, during which you need to finish the cast iron parts of this heating unit - handles and doors. Neither lime mortar nor ordinary paint is suitable for this work. Cast iron stove elements can be treated exclusively with special enamels in aerosol form that are resistant to high temperatures. Such enamels do not crack and retain their original appearance for a long time.

Before you begin applying enamel, you should degrease the handles and doors. This can be done using a solvent or alcohol. There is no need to prime the surface before applying enamel, because... the primer will still not withstand high oven temperatures in the future. This means that you can immediately proceed to the painting process.

First, you should thoroughly shake the can of enamel, and then spray the aerosol at a distance of about 25-27 cm onto the cast iron parts of the stove. Wait until the paint dries and you can start using the potbelly stove for its intended purpose. For work it is very convenient to use a special sprayer, the diagram of which is shown in Fig. 2.
