Bituminous mastic Technonikol: properties, consumption, application

Despite the abundance of materials and the so-called "builder’s paradise", the market does not stop looking for new favorites. And today this role rightfully belongs to the TechnoNIKOL company. A successfully proven, promising corporation, the key competence of which involves the production of materials for waterproofing, occupies a leading position in its market segment, both in Russia and in the countries of near and far abroad. Despite the stable popularity among the consumer and only positive consumer reviews about the materials produced, the company does not stop there and continues to actively improve the production of products, the main component of which is bitumen. The range of the company is constantly expanding and is not limited to the production of bitumen-containing mastics, the characteristics and application of which we will describe in this article. We will also talk about how productive the cooperation of TechnoNIKOL Corporation specialists and construction practitioners is, thanks to their joint work, the technical characteristics of the material are achieved that are in no way inferior to European counterparts and, sometimes, in many ways surpasses them..


Bituminous mastics: an overview of the main components of the material

Bituminous mastics, in terms of structural composition, represent a material characterized by multifunctionality, which determines its demand in a wide variety of construction industries, among which roofing and other construction manipulations take the main place, the purpose of which is to protect a room or surface from moisture. The basis of TechnoNIKOL bitumen waterproofing mastic is bitumen – an artificial or natural asphalt-like product of oil and petroleum products processing. So that mastics made on the basis of bitumen can fulfill their functional purpose – protection of the surface from moisture – polymer components are added to the bitumen mixture, which give the mastic waterproofing characteristics. Functional thickeners are considered another mandatory structural component of the described material, among which it is necessary to mention chalk, peat chips and ground asbestos. The presence of such components, declared by the manufacturer in the composition of the mastic, guarantees ease of use, a decrease in consumption and an order of magnitude higher thermal insulation characteristics..

Classification of bituminous mastics according to the method of application: how to make the right choice?

The extensive use of TechnoNIKOL bitumen mastic in various areas of construction determines a large number of types of material, the correct choice of which determines the durability and performance of the coating, but also its cost. Consider the main varieties of bituminous mastics in accordance with the method of their application:

Hot bituminous mastics

They are a plastic homogeneous mass based on asphalt-like refinery products with the addition of binders. The letters A and D on the marking of the material indicate the inclusion of antiseptic and herbicidal additives in the mastics. Before use, hot bitumen mastic TechnoNIKOL, price per sq. the meter of which is considered the determining factor in its choice, is heated to 160-190 degrees, after which it is applied in a heated form to the surface that has undergone a preliminary primer. After application, the mastic forms a durable coating with high elasticity, which does not tend to shrink, which is a distinctive feature of hot bitumen mastic. In addition, the advantages of hot bitumen mastic include its “non-porous” structure, efficiency of use at temperatures below zero, and the disadvantages – additional energy consumption in the preparation of mastic, as well as high labor costs and a high risk of fires;

Bituminous cold mastics

In view of the simplified technology of use, this type of bituminous mastic is more popular among consumers. Considering this, the use of cold-applied mastics, the manufacture of which is based on the use of bitumen, is gradually becoming a familiar way of arranging bituminous waterproofing. This is due to a number of indisputable advantages of this type of product manufactured by TechnoNIKOL, the main of which are the following:

  • The absence of the need for preheating greatly simplifies the work on applying the mastic;
  • Production of bituminous mastics of a wide range of colors, achieved by including special coloring pigments in the mastic;
  • Achieving the required consistency due to the addition of a solvent, which is important for cold solvent-based mastics;
  • The unique composition of cold-use mastics makes it possible to obtain a waterproofing layer that is resistant not only to atmospheric precipitation and temperature changes, but also to the damaging effect of ultraviolet radiation;
  • Using Technonikol bitumen mastic, you provide a long overhaul period of the roof, which to one degree or another determines the service life of structures and other structures involved in construction..

There are two groups of bituminous cold mastics, the fundamental differences in the composition of which necessitate their more detailed consideration. Cold mastics are divided into:

  • Cold bitumen mastics made with solvents;
  • Water-based cold bitumen mastics or so-called bitumen emulsions.

The first one is initially ready for use and is suitable for the organization of coating-type waterproofing, the arrangement of which is important even at negative temperatures. The presence of a solvent in the composition of the mastic leads to its instant evaporation and the formation of a monolithic layer of waterproofing. The main application of cold mastic is to organize the waterproofing layer of the roof. Despite the fact that the mastic dries out 12-24 hours after its application, it acquires its final properties no earlier than a week later..

Water-based cold bitumen mastic (bitumen emulsion) is produced using high-tech installations and modern materials, among which the main role is played by polymers and emulsifier. Unlike hot mastics and cold mastics made with the use of a solvent, the use of a bitumen emulsion contributes to the organization of an environmentally friendly and safe roof waterproofing system. After applying the bitumen emulsion, which is the know-how of the TechnoNIKOL corporation, the water evaporates, after which a monolithic waterproofing layer of high strength is formed.

The following advantages are characteristic of bitumen emulsions:

  • More convenient application process;
  • Absolute non-toxicity due to the absence of a solvent in the composition of the mastic;
  • Fire and explosion safety, which makes it possible to use bitumen emulsion inside residential premises;
  • Shorter complete drying time;

Despite a wide range of advantages, bitumen emulsion is characterized by the only limitation, which is at the same time its disadvantage – the seasonality of the specified product produced by the corporation..

Indeed, it is forbidden to store bitumen emulsions and carry out the necessary manipulations with them at temperatures below 5 degrees above zero, which is due to the loss of performance and the decomposition of the bitumen emulsion when water passes into a solid state of aggregation..

Classification of bituminous mastics by composition and their use

By composition, all varieties of bituminous mastics can be classified as follows:

  • One-component bituminous mastics, when using which the full set of properties of the finished waterproofing coating occurs after complete evaporation of water or other minor components;
  • Two-component bituminous mastics demonstrate their properties only after adding the second component, most often it is a hardener.

In accordance with the original component of the mastic, there are:

  • Bituminous mastics, the production technology of which does not imply their modification with polymers. This variety is undesirable to use for arranging the roof, while they are perfect for waterproofing foundations, since in this case it will not be influenced by frequent temperature changes;

  • Bitumen-polymer mastics are the most common type of bituminous mastic, intended mainly for roofing waterproofing, as well as for gluing roll roofing materials. In addition to its main purpose, bitumen-polymer mastic can be used to arrange waterproofing of foundations;
  • Bituminous-rubber mastics, the structure of which includes crumb rubber, are rarely used for arranging the roofing system, in view of the parameters of rubber crumb, which are not suitable for working with roofing systems;
  • Polymer mastics are the know-how of modern construction chemistry, which leads to their high cost and less distribution in the construction industry. However, their high mechanical, waterproofing, operational (declared service life is more than 20 years) characteristics and resistance to ultraviolet radiation without additional protection predict a great future for polymer mastics..

Spheres of application of bituminous mastics

Systematizing the above, we will designate the main areas of application of bitumen products of the TechnoNIKOL corporation.

  • Arrangement of a mastic roof, as well as repair work with a bitumen-polymer and bituminous roof;
  • As for the protection of the roof, the use of bituminous mastic is important for strengthening bituminous tiles and roll roofing materials, protecting the roof from overheating and exposure to ultraviolet radiation, as well as for applying conservation paint;
  • Roofing is not the only area of ​​application of bitumen mastic, which can also be successfully used for the installation of a waterproofing layer of various building structures, such as piles, foundations and basements;
  • Anti-corrosion protection of the foundation and gluing of thermal insulation boards – all this is carried out using bitumen mastic;
  • Arrangement and repair of internal premises is also not complete without the use of bitumen mastic. In this area, bitumen mastic is used for waterproofing premises with limited ventilation, for example, toilets, bathrooms, garages and loggias;
  • Installation of waterproofing terraces and pools is another direction of using TechnoNIKOL bitumen mastic.

Bituminous mastic consumption: basic norms

The consumption of bituminous mastic depends on the method of its application and the type of material on which it will be applied. Cold-type mastic is made on the basis of water or solvent, and its application is carried out without preliminary heating. The application of hot mastic provides a layer that does not shrink, and therefore, after application, it practically does not change its thickness. In addition, the consumption of bitumen mastic depends on the type of work carried out when using it. For example, in the process of gluing surfaces, the consumption of bitumen mastic is at least 0.8-1 kg per 1 sq. meter of surface, while when arranging a waterproofing layer with a thickness of 1 mm, this figure increases to 2-3 kg per square meter. meter. And if the thickness of the waterproofing layer is 2 mm – and even more than 3.5-3.8 kg per sq. meter in dry residue.

Bituminous mastic Technonikol is one of the most popular materials in the modern construction market in its field. According to the manufacturers, it is completely ready for use without preliminary preparation, implying modification with rubber, the presence of mineral fillers, organic solvents and other technological additives. Due to the unique composition of Technonikol bitumen mastic, the coating formed during its use is characterized not only by high adhesion to the base, but also by increased elasticity, moisture and heat resistance. The consumption of Technonikol bitumen mastic is 2.5-3.5 kg per sq. meter when arranging a waterproofing layer and 1 kg when gluing roll materials.

Features of the use of various types of bituminous mastics

Hot bituminous mastics: application features

Mastic belonging to the MBK-G series, which stands for “hot bitumen roofing mastic”, is considered an economy class product. Its composition includes oxidized bitumen and several mineral fillers and gives the finished product not only the highest penetrating power, but also excellent water repellency. Hot mastics are made and sold in briquettes, which are packed in specialized kraft bags, characterized by the presence of a siliconized inner layer. Despite the fact that a distinctive feature of such mastics is a low price, in the process of using them it is necessary to strictly follow all the rules..

The sequence of actions is as follows:

  • The working surface is cleaned of dirt;
  • The mastic must be heated to a temperature of 150-190 degrees;
  • Then it is applied to the surface using a roller or brush;
  • The applied material is leveled with a paddle.
  • Thus, the use of hot bitumen mastic contributes to the reliability, integrity and long service life of the roofing system..

Cold bituminous mastics: application features

A feature of cold bitumen-containing mastics is their readiness for use without any preparatory measures. Regardless of the type of cold mastic, be it bituminous emulsion or bitumen mastic on a solvent, the application of cold mastic on an insulated surface is carried out without any special features..

Today, Technonikol Corporation offers the consumer a wide range of bituminous mastics designed to successfully solve the problems of waterproofing underground and aboveground structures. For example, the universal bitumen-polymer mastic Technonikol No. 21 is very popular, intended for the arrangement of repair of all types of mastic roofs, as well as for solving various problems associated with the arrangement of waterproofing.

The sequence of actions when applying cold bitumen mastic:

  • The surface that needs waterproofing measures is cleaned of various contaminants such as dust, dirt, grease and ice. To clean the surface from small debris, use polypropylene brooms, various brushes designed for cleaning;
  • Next, a dry and clean surface is treated with a primer (TechnoNIKOL Corporation offers a consumer interested in high-quality waterproofing, a specialized TechnoNIKOL primer). The purpose of this event is to achieve the greatest adhesion of the insulated base and mastic. In this regard, it is common to use a bituminous primer in the process of preparing insulated surfaces, such as concrete slabs, cement-sand screed, before directly laying self-adhesive and weld-on waterproofing roofing materials;
  • The mastic is thoroughly mixed until a homogeneous mass is obtained;
  • Then it is applied layer by layer using a brush, roller or spatula, as well as using the pouring method, after which it is carefully leveled with a special paddle to achieve a uniform waterproofing layer. In this case, the layer of material should not exceed 1.5 mm, and each subsequent layer is applied after the final drying of the previous one. To ensure effective waterproofing of building structures, two layers of bituminous mastic are applied;
  • Having carried out the above measures, they proceed to gluing roll materials.
  • The consumption of bitumen mastic when arranging a mastic roof can vary from 3.5 to 5.7 kg per sq. surface meter.

When working with mastics, it is necessary to follow all safety rules indicated by the manufacturer. Works involving the use of mastic are prohibited in rooms lacking effective ventilation. It is also necessary to comply with fire safety rules prohibiting work with mastic near sources of fire..

You can familiarize yourself with the application of bitumen mastic in more detail by reading the instructions that the manufacturer places on the labels or in the accompanying instructions..
