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 carries the greatest semantic load, heating the living room. The fireplace is an important element of decor in private expensive cottages, creating the appearance of live fire and crackling firewood.
If the device is designed to supply heat, it should 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.
Purpose of adhesive solutions
Any bonding composition must have certain characteristics. Often the better the quality of the product, the higher its value. Adhesive for fireplaces and stoves, regardless of price, has a high degree of reliability and is not subject to destruction from temperature extremes. Specialists recommend using different adhesive mixtures for certain areas:
- Heat-resistant: for the foundation and base of the furnace, the glue must withstand temperatures ranging from -30 to +150 degrees; for the portal it is better that the composition does not collapse to +250.
- Heat-resistant: with a limit of up to +1000 degrees use for a chimney.
- Heat resisting: from 1300 and above apply in a chamber for a fire 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 improved parameters, lose a lot of certain advantages. Nevertheless, any adhesive mixture has the following properties:
- moisture resistance;
- the possibility of linear expansion;
- wear resistance;
- resistance to low temperatures;
- good heat transfer performance.
The higher the described indicators, the more reliable the composition for bonding.
Types of glue
There are compositions of natural and synthetic materials.
The natural ones include heat-resistant adhesives for stoves and fireplaces and heat-resistant samples with an allowable heating temperature of up to a thousand degrees. The main component of such mixtures is a liquid glass solution, which is mixed with refractory clay, sand and certain minerals.
Synthetic glue is considered heat resistant and is made from polymers or inorganic substances. So, phosphate compounds withstand heat up to 2000 degrees, and other specimens do not collapse even at 3000 degrees.
Refractory adhesives for stoves and fireplaces are also divided into:
- two-component, requiring mixing of the ingredients;
- dry formulations to be diluted;
- ready-made one-component mixtures.
Well-known manufacturers
The following brands of goods are leading the rating of popular adhesives in Russia:
- "K-77 parade";
- Terracotta
- "D-314";
- "Super Fireplace Thermo Clay";
- "Hercules";
- Scanmix Fire;
- "The stoveman."
"Parade K-77"
This option is ideal for stoves and fireplaces. The glue has a lot of positive reviews, including the following characteristics:
- increased fixing ability;
- complete drying time no more than 24 hours;
- adhesive strength with a base of at least 1.2 MPa;
- heat resistance with possible prolonged heating up to 800 degrees;
- additional increase in heat transfer from the stove and fireplace;
- ease of application;
- good smoothing ability;
- lack of swimming even on a vertical plane;
- excellent sealing of cracks in improvised heating facilities;
- convenient packaging of finished goods of 5 and 15 kilograms.
Of the minuses, experts note the impossibility of applying the composition on top of plastered surfaces, which is reported in the instruction manual.
Terracotta
Glue for stoves and fireplaces "Terracotta", used for facing works, is characterized by 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 must be diluted with ordinary water. The resulting mass is allowed to infuse for 15 minutes, mixed again and produced in no more than half an hour. Therefore, professionals do not recommend kneading huge portions of adhesive.
The Terracotta line also has special mixtures for masonry furnaces that withstand heat up to 1300 degrees and are among the best heat-resistant compounds.
The advantages of the simultaneous use of glue for cladding and mixture for laying bricks is their equivalent degree of thermal expansion, which prevents the formation of cracks in the joints and on the working surfaces.
"D-314"
The domestic manufacturer "Diola" is known for the budget version of heat-resistant glue for facing stoves and fireplaces. The composition is quite possible to carry out finishing work on heated surfaces, since it differs from ordinary building mixtures in a number of characteristics:
- high degree of elasticity;
- increased dimensional stability;
- withstanding heating to 800 degrees;
- use on brick, concrete and stone surfaces.
Experts note the high setting rate of glued surfaces, the viability of the solution for an hour, convenient packaging. Of the disadvantages, there is a need to apply a thickened layer on the facing material, in connection with which the composition consumption per 1 square meter is significantly increased.
Super Fireplace
The Plitonit brand has appeared on the domestic market as a branch of a German concern. Today the company has production facilities in a dozen Russian cities. The manufacturer positions tile glue for stoves and fireplaces “Super Fireplace Thermo Clay” as a one-of-a-kind heat-resistant composition with reinforcing fibers. The composition received excellent reviews by professionals for the cost-effectiveness in decorating furnaces and fireplaces with materials from ceramics, porcelain stoneware, artificial and natural stone. Also, the mixture can be used for putty and grout tile joints.
Along with adhesive mixtures, the company "Plitonit" produces thermal and heat-resistant compounds:
- “Thermo-Stop” - for the internal masonry of structures made of refractory bricks;
- “Thermo Masonry” - for the construction of external wall surfaces of the furnace;
- “Thermo Clay Masonry” - for masonry of heating structures made of clay;
- “Thermo Repair” - for repair work on surfaces subject to serious heat;
- "Thermo Plaster" - for plastering fireplaces, stoves and chimneys.
"Hercules"
Another affordable option for stoves and fireplaces. Hercules glue, like the previous ones, refers to heat-resistant compounds, but it differs in the ability to tolerate short-term heatings up to 1200 degrees. Of the significant inconveniences, master finishers note the difficulty of diluting the powder in water. To facilitate the procedure, the manufacturer recommends the use of mechanized methods of stirring 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
The Finnish Scanmix 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 benefits that users most often note are:
- heat resistance;
- increased mechanical strength;
- ease of application;
- production period up to 2 hours;
- high ductility.
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 the cost of construction.
"Pechnik"
This domestic sample of glue for fireplaces and stoves has been widely used among professionals. Despite the low parameter of maximum temperature, the composition is excellent for facing furnaces. It evenly lays down on glued surfaces, does not form crumbs, allows for high-quality masonry with a layer thickness of 5 mm or more. The economical consumption of a mixture weighing 1.5 kg per 1 square meter reduces financial costs. A good water-holding ability protects against the formation of cracks on surfaces subject to constant heating. The elasticity and heat resistance of the solution allow us to recommend glue for self-laying tiles on the outer furnace surface.
The opinion of experts
Since it is quite difficult for an average person 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 better - close to two hours.
- The possibility of uniform linear expansion will contribute to the durability of the structure.
- The environmentally friendly composition will not harm the body.
It is also important to remember that an expensive item is not necessarily the best, and a cheap item is not always economical. The buyer needs to understand for what work he chooses the mixture. For facing, a heat-resistant composition at a reasonable price is suitable. For laying stoves and fireplaces, it is necessary to give preference to a heat-resistant mixture with a small flow rate in terms of 1 square meter.
