Sealant and glue for fireplaces and stoves

The popularity of fireplaces and stoves is increasing every day, as they are not only beneficial, but also are great design solutions. The construction of such structures involves the use of special materials that can withstand high temperatures. This applies to both stone and glue, with which the frame or cladding is bonded.

Today on the market you can find substances based on natural and synthesized substances that are designed to solve various options. The advantage of such solutions and adhesives is that they do not need to waste time on their long-term manual preparation.

Sealant and glue for the fireplace are different substances, differing in several basic parameters. To understand their differences, one must consider the properties of these products.

Sealants are special formulations based on various chemicals.The main purpose of such mixtures is to fill seams, cracks and other formations in the frameworks of stoves, fireplaces, etc. They are able to withstand significant temperatures. According to this characteristic, it is possible to distinguish the main types of sealants:

  • heat-resistant pastes capable of transferring high-temperature mode to values ​​not higher than 350 degrees Celsius. They are used on the outer surfaces of stoves or fireplaces. Often sealants of this type close up cracks, joints and other openings in places with high temperatures.
  • heat-resistant and heat-resistant compositions are operated in places heated to 1500 degrees Celsius. The main purpose is to repair damage to the brickwork and other similar places where there is such a high temperature. Some varieties of such sealants calmly withstand the effects of open flame.

Selecting sealant for fireplaces and stoves, you should pay attention to its type and operating conditions. This will provide an opportunity to purchase a high-quality and reliable product that can solve a specific problem.

Adhesive for fireplace is a special solution, which is often used in laying.There are several types of similar compounds on the market:

  1. Heat-resistant solutions are able to withstand the effects (about 3 hours) of a temperature not lower than 140 degrees.
  2. Heat-resistant glue perfectly maintains the same temperature range as in the first paragraph, but here their properties are no longer violated after a certain time.
  3. Heat-resistant mixtures have the ability to withstand temperatures already in the region of 200 degrees without losing their basic properties.
  4. Heat-resistant, heat-resistant glue possess the characteristics of previously considered substances, but they can be used already when heated to 1000 degrees.
  5. Fire-resistant solutions retain their technical characteristics when exposed to open flame for at least 3 hours. It should be noted that this adhesive has a high chemical resistance, which prevents the occurrence of any reactions with active unburned particles.
  6. Refractory glue has the same parameters as fire resistant substances, but it can withstand the effects of fire for an unlimited time.

It should be noted that the purpose of the glue for fireplaces can also be divided into masonry and tile (finishing).Each of these types of solutions has a different adhesive stickiness and viscosity. Ready-made chimney solutions consist of several main components:

  1. Clay-cement binders, chamotte fiber, and many others. Not only the heat resistance, but also the adhesion of the solution depends on their combination.
  2. Binders These include aluminosilicate cements and kaolin. Also in some cases, add liquid glass and other components.
  3. Mineral plasticizer, based on talcochlorite flour.

It should be noted that the glue for the fireplace may have a different composition, which is combined to give it specific properties.

Silicone-based sealants can be attributed to the heat-resistant group of substances. Such solutions are able to withstand temperatures in the range from 250 to 300 degrees. Mixtures capable of withstanding high temperatures can be distinguished by color. They are often slightly reddish, indicating the presence of iron oxides. I use silicone sealants only for sealing chimney fissures, cracks, etc. in places where there is no direct exposure to direct fire.

The composition of such mixtures may differ, which allows them to be divided into acidic and neutral.The latter products are more versatile, while the latter have some limitations for use with metals, plastic, etc.


Sealants based on liquid glass do not have high plasticity, but are able to withstand the effects of open flame (temperature from 1200 to 1500 degrees). With their help, I carry out repair of through cracks in stoves, fireplaces and other similar systems. Often silicate sealants produce black, but gray solutions can also be found.


Acrylic-based sealants have similar properties to the previous type of products, but differ from them in somewhat better elasticity. The disadvantages include the phenomenon of hydrophilicity.


On the market of adhesives for furnaces, you can meet quite a few representatives who have their own unique characteristics. Before buying such products, it is advisable to study the reviews about them in various forums or consult with a specialist. Among all this diversity, there are several best brands of sealants and hot melt adhesives for fireplaces:

  1. Tytan is a silicate sealant.The substance can be used for sealing gaps and repair mechanisms, where the temperature does not exceed 1250 degrees.
  2. Krass. This product is a silicone based sealant. It has quality indicators of adhesion to concrete, brick, stone, etc.
  3. Profix is ​​a group of furnace adhesives. It is applied both when laying and gluing external structures. The material is able to withstand temperatures up to 700 degrees.

To protect metal furnaces, such as Statika Tetra, more and more often they use Inox aerosol based on stainless steel particles. Properly selected glue or sealant for the fireplace will not only get a solid construction, but also extend its service life for a long time.
