What to paint the metal stove in the bath

Choosing heat resistant paint for a metal oven

The main problem associated with the use of iron stoves for home and bath is the property of metal to oxidize under the influence of oxygen, liquid and always changing temperature, so the treatment of the metal stove with paint, can reduce the degree of exposure to various harmful factors to its surface.

When choosing a paint, you should pay attention to several indicators:

  • fire resistance, which should be at least 600 degrees;
  • absence of harmful impurities prone to combustion and release of toxic substances;
  • protection against corrosion;
  • water repellency.

Lime Mortar

Lime is an accessible material in every respect. Lime solutions have bactericidal properties, and after drying they are completely harmless and do not irritate the mucous membranes. A properly prepared lime mortar holds up well to plaster, stone and bricks, is not afraid of temperature fluctuations and can be used outside and in damp rooms, including baths.

For preparation of a solution it is better to buy slaked lime in the form of a dry powder. For whitewashing furnace equipment is recommended instead of water to use a ten percent solution of salt. Salt makes the coating hard and prevents cracking.

Dilute the lime powder in one third of the salt water, stirring the mass thoroughly until homogeneous. If the mortar is prepared from lime dough, it is also diluted with salt water to the consistency of liquid sour cream;. If the mortar is prepared from lime dough, it is diluted with salt water to the consistency of liquid sour cream. To neutralize possible yellowing, it is recommended to add diluted blue.

One liter of lime solution is enough for about two square meters of area. Accidentally soiled floors are not difficult to clean with clean water, but it must be done immediately, before the lime has time to dry.

Paint for heat-resistant sauna stoves in a wide range of products. Paint and varnish mixtures are classified according to their base components:

  • Organosilicon paints form a glassy film that retains its strength at 800 ° C, have good adhesion to the metal, not afraid of water;
  • Polyurethane. wear-resistant, can withstand heat up to 600 ° C, often used for boiler equipment. Minus. some compositions change color from the thermal effect;
  • Water-emulsion with acrylic filler is more suitable for the sauna or painting the stove side of the pre-bath, where there is no high humidity.

According to user reviews, several heat-resistant paints deserve attention:

  • “Hammerite”, “ELCON”. enamels with corrosion inhibitors;
  • Kudo enamels with silicon;
  • “Hansa” in a spray can or cans, produce about 16 shades;
  • Tikkurila grey or black with alkyd resin;
  • “Bosni”. a universal composition for many types of surfaces.

For your reference. For thin-walled furnaces it is recommended to choose coatings with heat resistance index of 800 850°C.

Acrylic-infused water-based emulsion coatings are more suitable for sauna or for painting the stove from the anteroom, where there is no high humidity.

Which one is better to use??

What to paint a metal stove in the bath? To do this, be sure to buy heat-resistant or organo-silicon enamels, varnishes that can withstand heat up to 6000. The layer must retain its monolithicity and prevent the formation of rust on structural steel, from which inexpensive bath “units” are made.

Typically dark colors are used, up to black. It increases the heat output of the oven. Use of aluminum-based paint is not recommended. The most popular are organosilicon enamels from Russian and foreign producers. In its composition:

When buying heat resistant paint pay attention to the intended use. It is available for the treatment of parts from fire, dry steam, steam and metal. If the marking indicates “KO” and the number 8. it is an organosilicon enamel that withstands the temperature of 8000.

And now let’s go over specific brands:

  • The leader among the domestic brands is “Cetra”. Available in a variety of heating temperatures. Black colored enamel is capable of withstanding heat up to 9000.

What to paint the inside of the metal stove in the bath? For this, it is better to use a fire retardant paint. Its only disadvantage is its high price.

Conventional anti-corrosion techniques in bath tanks

In private homes, in gardens, suburban areas almost every owner has a bath. Before the invention of two-component enamels, anti-corrosion, quality paintwork materials were used three technologies:

  • Aluminum powder. diluted with liquid glass withstands extreme temperatures of 700˚C, does not change the quality of water, is considered environmentally safe
  • Lime/cement solution. the components are mixed to a creamy state 1/1, after which, the tank is coated, dry the inside surface either chips (absorbed moisture is removed, the tank is filled with a new portion), or heat dryers
  • Iron grit. present on the shelves of most stores, is a filler for weatherproof paints (a mixture of powder with pentaphthalic varnish)

Modern coatings for corrosion protection

There are several product groups that reliably protect intermittently heated/cooled water tanks against rust. For example, CVES. two-pack anticorner on the basis of epilsilicate, zinc powder. In the field the product is applied on the surfaces cleaned of rust by brush, roller. The mixture is made by constantly adding B-component to the container with A-component.

After soaking, it is sufficient to strain the mixture to start the work. In winter, the object to be painted must be heated to a temperature of “dew point 3˚C. The surface should be prepared indoors no earlier than six hours before painting begins. The recommended temperature range for corrosion protection is 40˚C.15˚С. Humidity above 80%, humidity below 30% is not recommended.

Heat-resistant Zerta is designed for extreme conditions, used in petrochemistry, hydro and heating structures. It is not affected by overheated steam at periodic or permanent contact. Chimneys, furnaces, boilers are painted with this paint in one or two coats. Mineral oils, oil products, saline solutions do not influence the protective film formed after dyeing. Covering life is more than 7 years (for baths), in atmospheric conditions it is doubled.

Zinc-filled anticor enamel Ecocin forms protective gray film on the surface of a vessel, withstanding shocks, mechanical damages. This is relevant when cleaning, operating the tanks. no scratches remain when scooping with a ladle, cleaning tanks from scale.

on the choice of water tanks can be found in the article “Choosing the water tank in the bath”.

Enamels for potable water tanks KO-42 are not destroyed by high temperatures. The coloring mixture consists of zinc powder in ethyl alcohol with ethyl silicate solution. The two components are mixed before painting. This technique is called “cold galvanizing” because the ethyl vaporizes after application, leaving an even film of protective material on the surface.

How to clean a container from rust is told in this

KO-870 enamel consists of additives, silicon-containing varnish, fillers, pigments in the form of suspension. Manufacturers produce products in gray-silver, red-brown, yellow, green, black and white colors for the convenience of consumers. Purpose is to protect the metal from high temperature, humidity, aggressive environments. The impurities (salts) in the water are also not harmful to the paint. The material dries in four hours, hiding power of different colors is 100. 80 g per square.

Almost every country house in our country has a sauna.

At its construction the most important part is to install the oven.

To make it last as long as possible under the influence of high temperatures and high humidity, it requires treatment, including the use of special paints.

If you decide what paint to paint an iron stove in the bath, you need to choose compounds that are resistant to high and low temperatures and high air humidity. As well as those that will not emit toxic substances during bathing procedures. Organosilicon enamels meet these requirements best. They cost more than other heat-resistant paints, but also last longer. However, durability is directly dependent on proper surface preparation and following the coating technology.


Better than to paint the stove in the bath several times during its operation, to use the method of blistering metal with their own hands at home. Parts are covered with a thin layer of black protection and look more attractive than heat-resistant enamel. But when working with chemicals, don’t forget to wear protective gear. The work is carried out in several stages:

    Using a metal brush and then fine sandpaper, bring the surface of the parts to a steel luster. This operation is very important, the quality and durability of protection depends on it. So you should not be in a hurry.

  • butyl alcohol. 4 g;
  • Phosphoric acid. 150 g;
  • water 1 l.
  • The components are mixed and treated metal.
  • After the layer of mortar dries, it is removed with a solution of laundry soap and water.
  • Then the surfaces must be heated to 1500 and caustic soda must be applied with a paint gun.

After cooling the surfaces, you get a bath stove with a durable decorative finish.

What’s the best way to paint an iron stove in the bath??

Quite a common option is a sauna stove, laid out of brick. But metal products are also popular, since they are more affordable. You can buy them ready-made or weld them yourself. In any case, quite an acute question arises, than you can paint a metal stove and hot water tank in the bath.

Heat-resistant paints and enamels for saunas and baths

The choice of coatings for metal stoves is not too great. Only polyurethane or silicone based lacquers, enamels and paints have high heat resistance and other necessary properties.

  • Compounds based on polyurethane resins can withstand a maximum temperature of not more than 600 degrees, and they unpredictably change color shade when heated strongly.

What to consider when buying

Characteristics of heat-resistant paint of different colors, even of the same brand and the same manufacturer, may differ. They have the same base, but the pigments used for color are different. They affect the properties of compositions, and primarily on their hiding power and resistance to high temperatures. So before you paint an iron stove in the bath to prevent rust and stay in working order for a long time, find out what the maximum temperature it heats up to.

The most heat-resistant enamels are gray and silver. Aluminum powder is added, which has a flake structure and well protects metals from corrosion.

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

How to Paint a Bath

The best brands

Choosing what to paint a metal stove in the bath, you can consider the products of both foreign and domestic manufacturers. By heat resistance, hiding power, resistance and longevity our enamels are not inferior to imported ones. But these brands are deservedly considered the leaders:

In addition to heat-resistant enamels, you can also find patina compositions with the same properties, with the help of which you can decorate stoves and fireplaces, giving them an exclusive look.

Among foreign brands, the most popular are:

Kudo, Elkon, Cetra, Hansa, Bosni enamels are available not only in the usual flowing form, but also in spray cans. Choosing what to paint the stove in the bath, if it has a complex design or installed in an inconvenient place for painting, it is best to take exactly the spray paint. Or use a compressor with a sprayer.

Pay attention to the following:. use a compressor with a spray gun! There are suitable compositions for metal structures and other manufacturers on the market. Heat-resistant silicone enamels are labeled KO followed by a series of numbers, the first of which should be 8.

What to paint a stove, metal and brick

Many skilled craftsmen cook stoves for the bath with their own hands. Not just for the bath, though. To make the stove look presentable, it is better to paint it. The paint not only improves the appearance, but also protects the metal from splashing and reduces its contact with oxygen, and oxidation is slower. Brick stoves are painted less frequently, especially if they are made of good brick. But sometimes the brick starts to crumble unlucky with the batch, or overheated. Cracks in the masonry are even more common. They are putty with mortar, but to give a more attractive appearance, they are painted over. What’s much more often needed for a brick oven is to fix the doors: oven molding rusts, too. These are all the uses for heat resistant paint: for a metal or brick stove or for casting.
