How to choose a heat-resistant varnish for ovens, which one to buy? Heat-resistant enamels and varnishes - an overview and which ones to choose + Video Which heat-resistant varnish for ovens to buy? Lacquer for brick ovens makes it possible to create a good coating if it is of high quality and has heat resistance. Recently, heating with stoves has become even more popular, since this is not only obvious savings, but also an opportunity to create a unique atmosphere of a fairy tale, making your home a little more comfortable. Brickwork is very beautiful, so if a beautiful stove is made for you, you should not hide it under a layer of some kind of finishing material.

Heat-resistant varnish will make it possible to make the surface of the oven beautiful and well-groomed.

Methods of arranging a stove in a private house

There are many ways to equip a stove in a private house, but the most important point is not only the device, but also the decoration of the structure .

.. For comfort in the room, you need to try to make sure that the fireplace or stove fits well into the interior of the house. Most people opt for heat-resistant varnishes and enamels, which can create a hard-wearing finish that makes it easier to maintain your oven.

Characteristics of heat-resistant varnishes for ovens

Bricks intended for laying the oven already have certain characteristics in advance, which make it possible to withstand high temperatures.

During operation, the surface of the stove heats up over time, and then gives off the resulting heat to the air, which makes it possible to heat the room. But oven varnish has distinctive features. If you paint the stove with ordinary paint or varnish, at high temperatures this coating will quickly lose its useful appearance, properties, and the stove will become ugly.

Technologies for creating varnishes

Furnace varnish is created according to a specific technology, while the composition includes special additives that give certain properties to paints and varnishes, and organosilicon elements , which are needed to obtain a special coating for ovens.

Due to its interesting composition, this varnish differs from the usual ones:

  • Fast drying.

  • The ability to increase grip.
  • Heat resistance.
  • No possibility of peeling film.
  • The ability to penetrate deep into the brick.

Such varnishes differ from simple ones in that they are of better quality and are suitable for creating a heat-resistant coating.

To begin with, it is striking that such varnishes dry out quickly, and even at a temperature of +16 degrees, the first layer dries up in an hour. This enables the finisher to apply several layers per day. The high heat resistance also gives its advantages: you can heat the stove up to +250 degrees, and the stone and varnish will not be deformed and will not change their appearance.

Although the composition is heat-resistant varnish and has excellent characteristics, the material has other useful properties, including it can keep the surface of their brickwork from mechanical friction, moisture and the action of aggressive substances.Furnaces with heat-resistant surfaces are easy to use, easy to maintain, as the varnish coating cannot absorb chemicals and oils.

In addition, certain types of varnish can be used to coat metal elements, which are often used as decorative elements in brickwork.

What types of varnish are best?

To make the right choice when choosing a heat-resistant varnish for your oven, you need to take into account a number of certain parameters. Although lately there are a huge number of different varnishes on the market, and you can buy heat-resistant varnish for the oven at any suitable price, the best types are considered to be Siltek-1, Ko85, KO815. They entered the TOP among all types of varnishes, as they have distinctive features in terms of durability and service life.

Heat-resistant enamels and varnishes - an overview and which ones to choose + Video The most popular is KO85 varnish, which is often used not only for household work but also for industrial purposes to obtain a very durable coating.

    A layer of such a varnish can withstand up to +300 degrees, the composition is also resistant to temperature extremes, and can withstand up to -30 degrees. In addition, the material can be easily applied with a spray gun. You can thin the varnish to adjust the consistency.

  • Varnish with heat-resistant property KO815 can withstand from -60 degrees to +300. It makes it possible to get high-quality coverage and at the same time spend a minimum of material.

    The main advantage of the varnish is the possibility of using it in those ovens, which contact with fire is inevitable. At the same time, such a composition should be applied with a hot method, that is, the surface will harden, but only under the influence of infrared rays, which can sometimes complicate the finishing process.

  • Heat-resistant varnish Siltek-1 makes it possible to paint the oven even without prior application of a primer. At the same time, after application, the surface receives excellent aesthetic properties, but there is also a minus - the material is consumed very quickly and in large quantities.

Important: if you want to get a high-quality coating, you should apply the composition of your choice in at least 3 layers.

How is staining carried out?

There are many subtleties when applying varnish with heat-resistant properties, so they prefer to give such finishing work to masters of their craft. But if you want, you can do everything yourself. To do this, you will first need to clean the stove surface from all existing dirt.

Please note that if such work is carried out manually, then it will be easier for you to use a metal brush and soap solution, which will help not only get rid of dust, but also remove deep dirt.

If there is also oily contamination on the surface, you can use aggressive cleaning agents, but after that you will need to thoroughly rinse the masonry with water without additives in the form of other agents.

But thoroughly cleaning the surface is only the first stage in preparation when applying a special impregnation or primer. For many paints and varnishes that are resistant to high temperatures, the application of primers and impregnations is very important. Such substances will help to achieve better adhesion between the varnish and the brick of the oven. If you do not use these products, the varnish will begin to flake off over time.

To get good grip, let's take into account several important nuances.

The ideal temperature range for finishing is room temperature. Before you start varnishing, stir it carefully and slowly. Next, degrease the surface. When treating surfaces that are made of porous materials, apply at least three coats of varnish. By the way, fireplace varnish is great for similar products, but made of metal.

They can also process hobs or products made in the form of decorative forging. It is better to keep materials for preservation in cool places where there is no direct access to sunlight.


To achieve material compatibility, ideally, you should choose everything from one manufacturer. Before starting work, arrange a mini-test - process an inconspicuous place for others and see how the surface will look in the future.
