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

Today on the market you can find substances based on natural and synthesized substances that are intended to solve various options. The advantage of such solutions and adhesives is that there is no need to waste time on their long manual preparation.

Characteristics

Fireplace sealant and glue are different substances with several basic parameters. To understand their differences, you need to 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 frames of furnaces, fireplaces, etc. They are able to withstand significant temperatures. According to this characteristic, the main types of sealants can be distinguished:

  • heat-resistant pastes capable of withstanding high-temperature conditions up to values ​​not higher than 350 degrees Celsius. They are used on the outer surfaces of stoves or fireplaces. Often, this type of sealant is used to seal cracks, joints and other holes in places with high temperatures.
  • heat-resistant and heat-resistant compounds are used in places that heat up to 1500 degrees Celsius. The main purpose is to repair damage to brickwork and other similar places where such a high temperature is present. Some types of such sealants can easily withstand exposure to open fire.

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

Fireplace glue is a special solution that is often used for masonry. There are several types of similar compositions on the market:

  1. Heat-resistant solutions are able to withstand (about 3 hours) temperatures of at least 140 degrees.
  2. Thermal glue perfectly withstands 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 in the region of 200 degrees without losing their basic properties.
  4. Heat-resistant, heat-resistant glue has the characteristics of the 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 fire for at least 3 hours. It should be noted that such an 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 at the same time it can withstand exposure to fire indefinitely.

It should be noted that according to its intended purpose, glue for fireplaces can also be conditionally divided into masonry and tile (finishing). Each of these types of solutions has a different adhesive tack and viscosity. Ready-made fireplace solutions consist of several main components:

  1. Clay-cement binders, fireclay fiber and many others.Their combination depends not only on the heat resistance, but also on the adhesion of the solution.
  2. Binders. These include aluminosilicate cements and kaolin. Also, in some cases, water glass and other components are added.
  3. Mineral plasticizer based on talcum powder.

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

Silicone

Silicone-based sealants can be classified as a heat-resistant group of substances. Such solutions are capable of withstanding temperatures ranging from 250 to 300 degrees. Mixtures capable of withstanding high temperatures can be distinguished by their color. They are often slightly reddish, indicating the presence of iron oxides. I use silicone sealants only for sealing chimney cracks, 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, plastics, etc.

Silicate

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

Acrylic

Acrylic based sealants have similar properties to the previous type of product, but differ from them with slightly better elasticity. The disadvantages include such a phenomenon as hydrophilicity.

On the market of adhesives for ovens, you can find a lot of representatives with their own unique characteristics. Before buying such products, it is advisable to study reviews about it in various forums or consult with a specialist. Among all this variety, there are several of the best brands of sealants and hot-melt adhesives for fireplaces:

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

Inox aerosols based on stainless steel particles are increasingly being used to protect metal ovens such as the Statika Tetra. Correctly selected glue or sealant for the fireplace will not only allow you to get a solid structure, but also extend its service life for a long time.
