Mastic is a popular building material, which is produced by a large number of both domestic and foreign companies. Bitumast waterproofing mastics are especially popular among consumers. Today in our material we will consider in detail the characteristics of such materials.

Peculiarities

Bitumast waterproofing mastic occupies a leading position in the modern market in its niche. This is due to the fact that it is used in a wide variety of areas, and is also of high quality. So, using this material, you can waterproof concrete surfaces, foundation elements, external wooden structures and many other elements . As for the composition of the building material, on the one hand, it necessarily includes substances such as a corrosion inhibitor, antiseptic, insulating bitumen, organic solvent and plasticizer. On the other hand, the composition does not contain such harmful and toxic components as, for example, toluene.

In general, the purpose of Bitumast mastic is waterproofing, that is, protecting surfaces from excessive moisture, which can cause irreparable damage to a structure or structure . Bitumast mastics are used on materials such as concrete, metal and wood.

It should be borne in mind that there are strictly defined requirements that govern not only the procedure for using the substance, but also its storage. For example, the composition must be in a tightly closed container . It is also important to observe the temperature regime, which must be maintained in the range from -30 to +50 degrees Celsius. In addition, care should be taken to ensure that the container in which the substance is located is not exposed to direct and harmful effects of direct ultraviolet rays. Another caveat concerns adherence to the permissible humidity in the surrounding atmosphere. It is worth remembering that the mastic should not be located near either heating devices or open sources of fire.

Whenever possible, it is not recommended to store the material in residential premises . If this cannot be avoided, then you need to make sure that children do not have access to a container with mastic, and that the material is away from food.

The total shelf life of Bitumast construction waterproofing bitumen mastic has its own limits, which differ depending on what type of storage container you use. For example, for a sealed package, this period is 24 months, and for a metal container - 36 months.

Varieties

Due to the fact that Bitumast mastic is widely used in various spheres of human activity, several varieties of such material can be found in the modern construction market.

For example, there is a classification of building material, which divides mastic into 2 main types, depending on the method of its preparation

• Cold mastic - this is a material that is made without the use of high temperatures and without heat treatment. During the production of a cold product, chemicals such as petroleum solvents are very often used. Bitumast cold waterproofing mastic is sold ready-made, which is especially convenient for the user. At the same time, the material is also distinguished by its safety in the process of use. However, this building material is notable for its increased cost, therefore, it is not available for every buyer.
• Hot mastic is made immediately before application at the construction site.

In addition to those listed above, there are other types of mastic.

Rubber bitumen

The distinctive characteristics of this building material, first of all, should be attributed to its high adhesive ability and frost resistance. With the help of this material, gluing of roll roofing and waterproofing materials is very often carried out . In addition, it is important to note that the material must not be used in a closed environment.

Bituminous rubber

This type of material includes small rubber crumb, hence the name of the mastic variety. Due to this, such indicators of the material as the thickness and strength of the waterproofing layer increase. The use of such a mastic is allowed in conditions of weakly and moderately aggressive soils.

Roofing

The basic component of this category of building mastic is roofing bitumen. The distinctive characteristics of this material include its thick texture, due to which the mastic does not spread. Besides, the composition of the material includes such a valuable element as a herbicide, which prevents the growth and development of plants, as well as mosses and lichens, which often occurs on the roofs of buildings . Roofing mastic provides vapor barrier for roofing systems.

Thus, in the process of choosing and purchasing mastic, you should be as careful as possible, giving preference to such a type of material that will meet your individual needs.

How to use?

In order for the use of Bitumast waterproofing bitumen mastic to bring the desired result, it is necessary to follow the recommendations of specialists

• Stir the material thoroughly before using the mastic. In some cases, it can be diluted with substances such as white spirit, gasoline and other similar compounds.
• If construction work is carried out in conditions of low air temperatures (for example, below zero), then it is recommended to warm up the mastic beforehand. This must be done within 24 hours.
• The surface on which you will apply Bitumast construction mastic must be clean and dry. If it is characterized by a porous structure, then pre-treatment using a primer also from Bitumast is mandatory.
• It is recommended to apply the mastic itself using a paint roller, brush, mop or by spraying.

In addition to the standard rules listed above, during the use of mastic, you must absolutely adhere to safety precautions. So, in this regard, there are several generally accepted norms and principles.

• The use of mastic in closed living quarters is strictly prohibited. All work must be carried out exclusively in the open air.
• Remember that the waterproofing material is flammable, therefore, it is forbidden to light a fire or even smoke nearby.
• When working with bituminous material, the use of personal protective equipment is mandatory. This is due to the fact that in no case is the mastic allowed to get on the skin and mucous membranes. If this happens, then the affected area must be washed immediately, and also seek medical help from a specialist.

Subject to all the rules described above (both the use of the material and safety precautions), you will be satisfied with the result of your work, since the material will fully fulfill its functional purpose for a long time.
