Heat-resistant adhesive for tiles, fireplaces and metal

Heat-resistant adhesive is a very popular building material, widely used for many jobs: laying ceramic tiles, stone, marble, glass slabs, insulation materials, etc. There is a huge range of it. It is used not only for gluing, but also for sealing, for example, in bathroom cabins. Its application to the surface can be carried out in various ways. Apply the required amount of glue either pointwise or a continuous layer.

Composition and properties of the glue

The main components of dry glue are cement-sand mixture, as well as synthetic and mineral additives, which give the composition elasticity, heat resistance, high strength. In addition, they protect the masonry surface from cracking. The heat-resistant adhesive can be used for masonry and cladding works at an air temperature of -10 to +35 degrees C. After solidification, it has good adhesion, frost resistance and fire resistance (up to +1200 degrees Celsius).

Heat-resistant adhesive for tiles

Adhesive for laying tiles is mainly used for facing works in places with regular significant temperature changes. This heat-resistant adhesive is used for cladding chimneys, stoves, fireplaces, barbecue, firebox. It is also used for laying bricks, facing fireplaces and stoves with natural and artificial stone, clinker tiles. It is often used for work with heated floors.

How to choose glue?

To choose the necessary material for construction works is a great art. To prevent unnecessary loss of money, time and effort, it is necessary not only to understand the quality of the goods well, but also to have the necessary knowledge on its use. When choosing a heat-resistant adhesive, it is necessary to clarify the maximum temperature that this type of product can withstand , and also pay attention to where it is intended to use it. Think also about the materials that will be glued together, about their composition. The heat-resistant adhesive should dry quickly, it is necessary that it be sufficiently elastic. One must keep in mind its degree of adhesion: the higher it is, the better. High-quality heat-resistant adhesive for tiles should withstand temperatures of up to one hundred and twenty degrees. It is clear that when the product dries into the air a harmful substance is released, so it is necessary to remember the toxicity, the chosen adhesive. In addition, such a product will be used at high temperatures. It is best to focus on the adhesive with a minimum level of toxicity. The next step in your choice should be the water resistance test. Adhesive ability is provided by this particular feature. Experiment with the heating of the surface should be after forty-eight hours, after the product dries completely.

Fireplace glue is heat-resistant

The fireplace in the house is the embodiment of coziness, comfort, beauty, elegance. For its construction, as a rule, brick, mixture and glue are used. The choice of material for masonry of the fireplace stove is quite an important stage. Sometimes savings can lead to unpleasant consequences. Qualitative glue for a fireplace - heat-resistant composition, which has the following characteristics:

• Elasticity, which helps to preserve the structure of the masonry as much as possible;
• Fire resistance;
• Has in the composition a binder fibrous substance.

These qualities allow the use of heat-resistant adhesive for tiling, as well as for fixing the plaster mesh and external stone processing. Galvanized plaster mesh is fastened with nails to the surface, and the top is tightened with the composition. The result is a fairly flat and stable surface.

A heat-resistant adhesive for furnaces and fireplaces can withstand fairly large temperature differences.

Glue for metal

Glue for metal is a heat-resistant, unique adhesive compound with high strength. It differs not only in its composition, but also in its application method. This can be point applications and solid, the entire surface area. A good heat-resistant adhesive for metal can withstand temperatures of up to four hundred degrees. When choosing it, you should pay attention to the time of its drying, as well as the amount of toxic substances released, which is unambiguously important.

Surface preparation

The surface of the metal, as a rule, is sufficiently contaminated with different paint residues, oils or corrosion. Get rid of this can be mechanical and chemical.

Mechanical treatment - cleaning the surface by abrasive (abrading) effects, for example when using sandpaper, sandblast or shot blasting machine or a simple metal brush. The use of this kind of treatment not only cleans the surface, but also makes it more rough, thereby increasing the surface area of the interaction of the adhesive with the metal, and, consequently, the bonding strength.

Chemical treatment - exposure to a cleaned metal surface with a solution of alkali, acid or a special compound for cleaning and removing rust. Cleaning in this way occurs more quickly, is cheaper, and due to the formation of a chemically stable layer on the metal surface, the strength and longevity of the adhesive joint increases significantly .

Security measures

Work with glue requires compliance with certain safety rules, as it includes cement, which can irritate the mucous membrane. If accidentally ingested into the mouth, nose, or eyes, wash immediately with water. When working with heat-resistant glue in its dry form, a respirator should be used to protect the respiratory organs from dust.
