Everything you need to know about adhesive mastic

Today, a wide range of modern materials is presented on the construction market, the use of which, due to their excellent physical and technical characteristics, contributes to a better and faster performance of all types of work - from assembly to finishing.

One of these is adhesive mastic, without which the installation of stoves or fireplaces is currently indispensable. In this article we will tell you everything about this building material, define its features, varieties, popular brands, as well as areas of application.

Adhesive mastic is a type of building material that belongs to the category of adhesives. This substance is characterized by excellent binding properties. It has certain characteristics and properties that are clearly spelled out in GOSTs and are controlled by these regulatory documents.

According to GOST 24062-80 “Rubber adhesive mastics. Technical conditions ”the material must have certain technical parameters.

• Connection strength - from 0.12 MPa (kgf / cm²) to 0.32 MPa (kgf / cm²). This parameter depends on the brand of mastic and the gluing time.

• Viscosity - 2-9 (20-90) P;

• Volatile components in the composition - no more than 45%;

• Water absorption - from 0.5 to 1%.

A material parameter such as density, measured in kg per m3 (kilogram per cubic meter), depends on the brand of the binder adhesive.

The material has a number of advantages, among which it is worth noting:

• high strength;

• excellent adhesion to other materials, finishing and roofing;

• high coefficient of bio- and water resistance;

• resistance to temperature extremes;

• long service life - reliable manufacturers who produce high-quality material give a guarantee for at least 10 years;

• elasticity;

• high viscosity index - this allows the substance to be applied to any type of surface, thereby increasing the scope of its application.

Previously, for the manufacture of adhesive mastic, only the resin of the mastic tree was used. But such production is very time consuming and material, since the initial product - the resin of the rubber tree - was quite expensive. That is why more affordable raw materials are used in modern production for the manufacture of adhesive mastic:

• synthetic rubber;

• solvent;

• filler;

• polymer resins.

There are many types of adhesive polymer resins that are used today for sealing window openings, flooring, laying tiles and simply for waterproofing. Absolutely all types of such mastic have high adhesive resistance and approximately the same composition. Let's take a closer look at the main types of substances.

• Bituminous. Bitumen oil resin is a versatile product that is often used in the process of roofing, installation of vapor barrier and waterproofing material. It is heat and moisture resistant, viscous, elastic, durable and reliable. Consists of bituminous binder, antiseptic, herbicides and filler.

• Shale sealing non-curing MSU. The composition includes petroleum products, polymer additives, plasticizers and fillers. It is used for sealing and sealing glass enclosures.

• Refractory. The basis of the material is inorganic substances. Withstands very high temperatures, which is why refractory polymer resin is used in the process of insulating furnace installations and gas ducts.

• Adhesive based on FAED. It is a heat-resistant adhesive mastic. This type of substance can be used in both acidic and alkaline environments.

There are other types of adhesive mastics on the market: waterproofing acrylic, butyl rubber, soundproofing, roofing.

Among the existing manufacturers of adhesive resins, it is worth noting:

• "Terracotta";

• Neomid Supercontact;

• Calorygeb;

• Tytan;

• Collafeu.

Each of the above brands guarantees high quality and long service life of their products, which, before entering the consumer market, pass all the necessary laboratory tests, comply with norms and standards, and are certified.

Due to its excellent properties, high technical parameters and a variety of assortments, the scope of application of adhesive mastic is wide and varied.

For the device and decoration of stoves and fireplaces, both professionals and amateurs of repairs also choose mastic.

Most often, such an adhesive is used during installation:

• floor covering;

• finishing materials;

• wall elements;

• roofing.

For each type of construction work, there is a separate type of adhesive mastic, which has certain properties and characteristics. Its use makes it possible to reliably connect roll, tile, floor and roofing materials with any type of base. The main thing is to choose the right type of such a layer, and then a high-quality and reliable connection is guaranteed.
