Technical characteristics and rules for the use of TechnoNIKOL 24 mastic

Views

Many varieties of bituminous mastics are produced under the TekhnoNIKOL trademark, which are used in various fields of construction. Such materials are classified by both composition and method of use.

The latter classification includes hot and cold mastics.

Hot mastics are a plastic, homogeneous and viscous mass. The main components of the material are asphalt-like components and binders. On some packages there is letter marking A (with the addition of an antiseptic) and G (herbicidal component).

Hot mastic needs to be warmed up (up to about 190 degrees) before being applied to the work surface. After hardening, the agent forms a reliable highly elastic shell, eliminating the risk of shrinkage during operation. The main advantages of the material include a homogeneous structure without pores, the ability to work at negative ambient temperatures.

Its disadvantages are increased construction time and high fire risks associated with heating the bitumen mass.

Cold mastics are considered easier to use. They contain in their composition special solvents that give the solution a liquid consistency. Due to this feature, the materials do not need to be preheated, which simplifies construction activities and reduces the associated costs.

In addition to these advantages, cold mastic is in great demand, due to the ability to dilute the composition to an optimal consistency and color the solution in the desired color.

When hardened, the material forms a strong waterproofing shell on the surface, which is resistant to precipitation, sharp temperature fluctuations and to the effects of sunlight.

Advantages and disadvantages

In hardware stores, you can see many types of mastics, but mastic No. 21 stands out for its positive properties. She has been the leader among such products for many years. And all thanks to the following advantages:

• It is sold ready-made, does not require additional dilution;
• Since it can withstand different temperature indicators, it can be used at any time of the year, as well as in all weather conditions. It is allowed to use at subzero temperatures, even in such negative conditions, it does not lose its qualities;
• Before work, the solution does not need to be warmed up, and this significantly reduces the time for work;
• Variety of color palette, which allows you to apply it to different surfaces, while maintaining the color combination;
• It can be diluted with solvents to obtain the desired performance;
• Its use significantly increases the waterproofing of the building;
• It helps to increase the service life of the structure itself, to which it was applied. And the following repair work is required after a longer period.

Subtleties of application

The technology of waterproofing the surface with hot and cold mastics has some differences. Before applying both compounds, it is necessary to prepare the surface to be treated. It is cleaned from various contaminants: debris, dust, plaque. Hot mastic must be heated to 170-190 degrees. The finished material should be applied with a brush or roller, 1-1.5 mm thick.

Before applying cold mastic, the previously prepared surface must be primed. Such measures are necessary to improve adhesion. After the work carried out, the mastic should be thoroughly mixed until a homogeneous mass is achieved.

Cold-used materials are applied in several layers (the thickness of each should not exceed 1.5 mm). Each subsequent waterproofing membrane should be applied only after the previous one has completely dried.

Classification of mastics by composition

There are several types of cold-use bitumen mastics, classified according to their constituent components.

• Solvent based. These are ready-to-use materials that are allowed to work at subzero temperatures. The agent applied to the surface hardens after a day due to the rapid evaporation of the solvent. The result is a monolithic waterproofing coating that reliably protects the structure from moisture.
• Water based. Water-based mastic is an environmentally friendly, fire- and explosion-proof product with no odor. It is characterized by fast drying: it takes several hours for it to completely harden. Emulsion mastic is easy to apply, it is absolutely non-toxic. You can work with it indoors. The disadvantages of emulsions include the inability to use and store at low temperatures.

There are also several types of bituminous mastics.

• Rubber. Highly elastic mass, which received the second name - "liquid rubber". Effective, durable and weather-resistant materials that can be used as stand-alone roof coatings.
• Latex. Contains latex, which gives the mass additional flexibility. Such emulsions are subject to coloring. Most often they are used for gluing roll cladding.
• Rubber. Includes a rubber fraction. Due to its anti-corrosive properties, it is used for waterproofing metal structures.
• Polymeric. The mastic modified by polymers has increased adhesion to any substrates, it is resistant to temperature fluctuations and negative weather influences.

You can also find unmodified solutions on sale. They do not contain improving additives, due to which they quickly lose their performance during heating, freezing, temperature extremes and other factors. Such features do not allow the use of unmodified emulsions for roofing. Their main purpose is to waterproof foundations.

In accordance with the number of components, mastics can be one-component and two-component. The first is a mass completely ready for application. Two-component polyurethane - materials that need to be mixed with a hardener. These formulations are intended for professional use. They have higher technical characteristics.

Storage and use tips

When working with bituminous mastics, it is necessary to comply with all safety requirements prescribed by the manufacturer of construction products.For example, when carrying out measures for waterproofing structures, you must follow the fire safety rules.

When using mastic indoors, it is important to worry about creating effective ventilation in advance.

To perform work on waterproofing the surface with high quality, you need to heed the advice of experts:

• all work should be carried out only in clear weather at a temperature not lower than -5 degrees - for water-based mastics, and not lower than -20 - for hot materials;
• for quick and high-quality mixing of the composition, it is recommended to use a construction mixer or a drill with a special attachment;
• surfaces located vertically must be processed in several layers (in this case, the mass should be applied from the bottom up);
• at the end of the working process, all tools used are thoroughly washed with any inorganic solvent.

In order for the mastic to retain all the consumer properties declared by the manufacturer, you need to take care of its proper storage. It should be kept closed in a dry place, away from open flames and heat sources. Water emulsions must be protected from freezing. To do this, it must be stored only at positive temperatures. When freezing, the material will lose its performance.

You can use household chemicals and soap solutions to combat particularly stubborn stains. Careful preparation will help you get the desired result.

Preparatory work begins with cleaning the surface from all types of dirt, this applies to dust, and greasy stains, and streaks, etc.

In order for the product to better adhere to the surface, you can resort to applying a special primer. It must be applied in advance. The mastic should be applied to a dry surface.

If necessary, you can add a solvent to get the desired consistency, you can choose toluene, white spirit or nefras. In this case, the solvent can be added only after mixing the mastic; on average, this process is carried out within 10-15 minutes. It is added little by little so that it is evenly distributed in the composition. Next, the solution should stand for five minutes.

The distribution of the solution should be done carefully and slowly so that the layers are even. To do this, you can use rollers, brushes, spatulas. You can also apply a fill method. If work is underway on waterproofing the roof, then mastic is allowed to be poured, and then it is distributed with special squeegees.

After applying the mastic solution, they proceed to laying the roll material.Permissible temperature readings range from -20 degrees to +40 degrees. The layer dries up in 12-24 hours, this process is influenced by the climatic conditions where the work is carried out. So at normal room temperature it takes 24 hours. It takes a week for complete hardening.

The distribution of the solution should be done carefully and slowly so that the layers are even.
