Peculiarities

To date, the components of the heat-resistant glue are several elements, Each of them has special properties:

  • sand and cement;
  • a mixture of plasticizers (ensures the highest show elasticity and does not allow the destruction of the connecting layers);
  • Synthetic additive (improves the thermal properties of glue).

Often the manufacturer can add refractory clay into the heat-resistant glue. This is done in order to provide a strong compound of substances and increase the stability of the spike location to the sharp jumps of temperature.

High-quality heat-resistant glue, which will be used in the future, should be characterized by some properties:

  • linear extension;
  • resistance to wear and moisture;
  • The temperature minimum of stability is not less than three hundred degrees;
  • Resistance to high and low temperatures at the same time;
  • environmental safety;
  • The composition should be universal, suitable for both internal and external work;
  • good heat exchange ability.

Varieties

When choosing a heat-resistant glue, it is necessary to consider the area of ​​use. If one composition is most effective for facing the fireplace, oven, the facade of residential buildings, then the other is suitable for natural stones and glass, the third – for gluing metal elements. And when gluing kitchen utensils, it is more practical to use a special non-toxic heat-resistant adhesive composition.

Separate categories of heat-resistant glue have its own distinctive components that determine its area of ​​use. In general, the heat-resistant glue is divided into two main categories: natural and synthetic mixture. The glue category is indicated on the label.

Such formulations are resistant to acid and moisture. Often used to glue graphite and different metals.

The heat-resistant dielectric glue in composition is divided into dry and pasty mixture.

Each of them has certain characteristics that will help you decide on the right product.

  • One-component composition for gluing ceramic tiles. A acrylic mixture is taken as the basis, into which resin and various modifiers are added. Has a high adhesion indicator, adjust the position of the tile is within twenty minutes.
  • Two-component aluminosilicate rubber adhesive composition. Made on the basis of two ingredients – polyurethane and epoxy resin. When using them, you need to mix well. This glue is known as fast-hardening, time to adjust – insignificant.
  • Dry mixes. As a basis for the manufacture, cement is taken with elevated characteristics of elasticity and adhesion. The polymer modifier in the adhesive mixture does not make it possible to form cracks at high temperature leaks and during the sealing of binders.

  • The best option for gluing aluminum and other metals is a two-component polyurethane-epoxy glue. It contains chemical components that ensure the reliability of the attachment. It should be noted that the two-component adhesive composition is stirred with a hardener, in a ratio of one to one. Often proportions can change, depending on the purpose.
  • Bathroom, bath or sauna – the most susceptible placement of the room, so when choosing an adhesive composition, you need to remember about it. Before buying, consider, to what basis the ceramic tile (to plaster, old caficard, plasterboard), the tile of the tile and its properties to the absorption of moisture will be glued down (it affects the absorption of glue), the size of the tile (the greater the tile parameters, the thicker it is necessary to lay the glue ), surface area and t. D.

Next, it all depends on your preferences and characteristics of the room in which facing work will be conducted. For example, in the bathrooms it is recommended to choose a dry composition, which is the basis of cement. At the finished adhesive compositions there is one important nuance: they have a higher price than the dry analogs. Apply ready-made mixtures needed on perfectly smooth surfaces. Nevertheless, many still prefer to acquire a dry mix, it is more accessible at cost and optimal in its characteristics.

Tips for use

  • First of all, it is recommended to prepare the covered surface. It should be durable, smooth, purified from lime, oil, fatty substances, dust and dirt, as they can reduce adhesion glue. When gluing to the base, which is strongly absorbed, it is necessary to produce it in advance using a primer emulsion. Leave it for complete drying for several hours.

With a weakly absorbent basis, it is also recommended to process specially intended composition. Prepare the surface in a couple of days before the start of facing works.

  • When working with dry mixtures, it is required to prepare the surface and wait about an hour. Glue bred clean water in a ratio of about a quarter of a liter per kilogram of a dry mixture. With stirring, it is best to use a drill or a special stirrer to avoid the appearance of clots and lumps.
  • Algorithm for working with glue such: with the help of a spatula, the composition is applied to the desired surface, smoothed around the perimeter. Next tile presses (it is amenable to correction for about fifteen minutes after gluing). It is important to remember that the thickness of the infused mixture should not exceed more than one centimeter.

Shutting the seams occurs after the end of the mounting work, two days later.
