The fashion for fireplaces that burst into private construction at the end of the 20th century has not subsided to the present. Mounted decorative devices or folded Russian stoves not only attract attention with their original design, but also have a functional purpose. In an ordinary village house, the stove, which heats the living space, carries the greatest semantic load. The fireplace is an important element of decor in private expensive cottages, creating the appearance of a live fire and crackling firewood.
If the device is designed to supply heat, it must last a long time and be strong enough. To prevent destruction or deformation of the structure, experts recommend using heat-resistant glue for stoves and fireplaces.
Appointment of adhesive solutions
Any adhesive composition must have certain characteristics. Often, the better the quality of the product, the higher its cost. Glue for fireplaces and stoves,regardless of the price, it has a high degree of reliability and is not subject to destruction from temperature changes. Experts recommend using different adhesive mixtures for certain areas:
- Heat-resistant: for the foundation and base of the furnace, the adhesive must withstand temperature fluctuations from -30 to +150 degrees; for the portal it is better that the composition does not collapse to +250.
- Heat resistant: up to +1000 degrees use for chimney.
- Heat-resistant: from 1300 and above are used in the furnace chamber.
Quality
Manufacturers of glue for fireplaces and stoves are constantly improving their product, explaining this by the struggle for customers. Some are working on the versatility of the composition. Others, in the pursuit of quality and improvement in parameters, lose a lot of certain advantages. However, any adhesive mixture has the following properties:
- moisture resistance;
- linear expandability;
- wear resistant;
- low temperature resistant;
- good heat transfer performance.
The higher the described indicators, the more reliable the composition for gluing.
Types of glue
Distinguish between compositions of natural and synthetic materials.
Natural include heat-resistant adhesives for stoves and fireplaces and heat-resistant samples with a permissible heating temperature of up to a thousand degrees. The main component of such mixtures is a liquid solution of glass, which is kneaded with refractory clay, sand and certain minerals.
Syntheticglue is considered heat-resistant and is made from polymers or inorganic substances. So, phosphate compounds withstand heating up to 2000 degrees, while other specimens do not collapse even at 3000 degrees.
Also refractory adhesives for stoves and fireplaces are divided into:
- two-component, requiring mixing of ingredients;
- dry formulations to be diluted;
- ready-made one-component mixtures.
Famous Manufacturers
The rating of adhesives popular in Russia is headed by the following brands of goods:
- K-77 Parade;
- "Terracotta";
- "D-314";
- "Super Fireplace Thermo Glue";
- "Hercules";
- Scanmix Fire;
- "Oven".
K-77 Parade
This option is ideal for lining stoves and fireplaces. The glue has a lot of positive reviews, including the following characteristics:
- increased holding power;
- complete drying time no more than 24 hours;
- strength of adhesion to the base is not less than 1.2 MPa;
- heat resistance with possible long-term heating up to 800 degrees;
- additional increase in the heat transfer of the stove and fireplace;
- ease of application;
- good smoothing ability;
- no flow even on a vertical plane;
- excellent sealing cracks in makeshift heating installations;
- convenient packaging of finished goods in 5 and 15 kilograms.
Of the minuses, experts notethe impossibility of applying the composition over plastered surfaces, which is reported in the instruction manual.
Terracotta
Adhesive for stoves and fireplaces "Terracotta", used for facing works, has high adhesive properties and increased heat resistance with an allowable limit of about 400 degrees. The composition is produced in bags weighing 5 and 25 kg in the form of a dry mixture, which is to be diluted with plain water. The resulting mass is allowed to brew for 15 minutes, mixed again and produced in no more than half an hour. Therefore, professionals do not recommend kneading huge portions of the adhesive.
The Terracotta line also has special mixtures for laying stoves that can withstand heating up to 1300 degrees and are among the best heat-resistant compositions.
The advantage of using cladding adhesive and brick laying mix at the same time is their equivalent degree of thermal expansion, which prevents cracking in joints and work surfaces.
D-314
The domestic manufacturer "Diola" is known for the budget option of heat-resistant glue for lining stoves and fireplaces. The composition is quite possible to carry out finishing work on heated surfaces, since it differs from conventional building mixtures in a number of characteristics:
- high elasticity;
- increased dimensional stability;
- withstanding heat up to 800 degrees;
- application on brick, concrete and stone surfaces.
Experts note the high setting speed of the glued surfaces, the viability of the solution for an hour, convenient packaging. Among the shortcomings, there is a need to apply a thickened layer on the facing material, in connection with which the consumption of the composition per 1 square meter increases significantly.
Super Fireplace
The Plitonit trademark appeared on the domestic market as a branch of the German concern. Today the company has production facilities in a dozen Russian cities. The manufacturer positions the tile adhesive for stoves and fireplaces "Super Fireplace Thermo Glue" as a one-of-a-kind heat-resistant composition with reinforcing fibers. The composition received excellent reviews from professionals for the cost-effectiveness of finishing stoves and fireplaces with materials made of ceramics, porcelain stoneware, artificial and natural stone. The mixture can also be used for puttying and grouting tile joints.
Along with adhesive mixtures, Plitonit produces heat- and heat-resistant compositions:
- "Thermo Stop" - for internal masonry structures made of refractory bricks;
- "Thermo Masonry" - for the construction of external wall surfaces of the furnace;
- "Thermo Masonry Clay" - for laying heating structures made of clay;
- "Thermo Repair" - for repair work on surfaces subject to severe heat;
- "Thermo Plaster" - for plastering fireplaces, stoves and chimneys.
Hercules
Another option with a reasonable price,designed for stoves and fireplaces. Glue "Hercules", just like the previous ones, belongs to heat-resistant compounds, but differs in the ability to tolerate short-term heating up to 1200 degrees well. Of the significant inconveniences, master finishers note the difficulty of diluting the powder in water. To facilitate the procedure, the manufacturer recommends using mechanized mixing methods or an electric drill with a special nozzle. After a few minutes, the composition becomes plastic and must be worked out within one hour.
Scanmix Fire
Scanmix Finnish mixture, packaged in 25 kg, is used not only for facing, but also for masonry work in the construction of solid fuel stoves or fireplaces. The most frequently reported benefits by users are:
- heat resistance;
- increased mechanical strength;
- ease of application;
- working period up to 2 hours;
- high plasticity.
In addition, the consistency of the resulting solution does not require any special skills. The composition is easily applied in a thin layer, which reduces labor costs and saves construction costs.
Pechnik
This domestic sample of glue for fireplaces and stoves has found wide application among professionals. Despite the low parameter of the maximum withstand temperature, the composition is excellent for lining furnaces. It evenly lays down on the glued surfaces, does not formcrumbs, allows high-quality masonry with a layer thickness of 5 mm. The economical consumption of a mixture weighing 1.5 kg per 1 square meter reduces financial costs. And good water-holding capacity protects against cracking on surfaces subject to constant heat. The elasticity and heat resistance of the solution make it possible to recommend the adhesive for self-laying tiles on the outer surface of the oven.
Expert Opinion
Since it is quite difficult for the layman to decide on the correct composition for stoves or fireplaces, experts recommend paying attention to the following points:
- The term of use of the composition should be at least 30 minutes, and preferably closer to two hours.
- The possibility of uniform linear expansion will contribute to the durability of the structure.
- Eco-friendly composition will not harm the body.
It is also important to remember that the expensive item is not necessarily the best, and the cheapest item is not always economical. The buyer needs to understand for what kind of work he chooses the mixture. For cladding, a heat-resistant composition is suitable at an affordable price. For laying stoves and fireplaces, it is necessary to give preference to a heat-resistant mixture with a low consumption in terms of 1 square meter.
