What is waterproofing mastic? What firm of waterproofing mastic to buy?

Any structure requires the organization of a whole range of measures to protect it from moisture, precipitation and other external environmental influences. As for concrete and structures based on it, this material is different in that it absorbs moisture well, which, unfortunately, affects its quality over time. In this regard, all buildings must be protected from moisture in advance, for this you can use waterproofing mastic.

What is a waterproofing mastic?

It is a mixture of various substances for gluing, cementing, coating of cracks and voids in order to make the surface impermeable to water. What is mastic waterproofing? It consists of oil, bitumen, astringent, organic solvent, mineral filler, plasticizer and antiseptic. The main feature of this material is compatibility with many waterproofing elements. In other words, mastic is a certain composite, which is a highly stable glue mass. In addition, mastic waterproofing (MHTN) - it is relatively cheap, very reliable and does not require special skills when working with it material.

Application of mastics

For the implementation of construction and finishing works of various levels, mastic waterproofing "TECHNONICOL" (24 MHTN) based on bitumen was widely used. Its popularity is associated with the universal performance characteristics of the building material, thanks to which it is practically not replaceable when:

• The construction of the roof of all levels.
• Installation of the foundation.
• Flooring of floors.
• Sealing of window and doorways.
• A device for seamless coatings, for example for swimming pools.
• Arrangement of various engineering communications.
• Pipeline laying.

In addition, mastic waterproofing (24 MHTN) is used to seal various joints and junctions, to protect against atmospheric precipitation of metal structures and assembly seams, for coating insulation of various surfaces of concrete, cellars, loggias, wooden structures, bathrooms, as parquet glue , For anti-corrosion protection of car body parts.

Types of Mastics

There are several types of mastics, for example, hot and cold. The first are prepared directly on the construction site before the beginning of the work on waterproofing. One of the most important indicators of this mastic is its cheapness in relation to the cold. Waterproofing mastics "TECHNONICOL" of the second type are manufactured at the enterprise. There bitumen mixed with various fillers and components and packed in a special container - metal buckets of 20 liters. This building material is fully ready for use, it does not need to be heated and add various substances.

There is another kind of mastic - waterproofing material based on acrylic. It is an excellent insulator of concrete from moisture. After the application of acrylic mastic, the surface becomes resistant to cracking, which can result from uneven shrinkage of the foundation or other movements in the structure of the building.

Properties of mastics

Hot mastic based on bitumen is an ideal means for protecting all surfaces from the appearance of mold, rust, dampness. This material has an excellent penetrating power, filling the pores of the upper layer of concrete, thereby preventing moisture from penetrating into the interior. Its impact on the design is possible not only outside, but also inside the building.

Cold mastic waterproofing "TECHNONICOL" 24 MGTN is able to resist the impact of water vapor. In comparison with roll insulating materials, this kind creates a seamless coating due to a certain method of application, because the joints are the weakest link in the waterproofing. Mastic after hardening does not crack and has increased strength. It is applied to the surface with the help of conventional construction tools, and no special difficulties arise in this case.

Physical properties of bitumen mastics

Due to its properties, mastic "TECHNONICOL" is recommended for use for external and internal works on insulation protection of building structures. Physical properties of bituminous material:

1. Flexibility and elasticity.
2. Excellent water resistance.
3. In the solidified state, high strength.
4. Homogeneous structure.
5. Versatility.
6. Effective use on porous and uneven surfaces.

Technical characteristics of waterproofing mastics

Industrial enterprises that specialize in the production of various building materials produce mastic waterproofing Various brands and specifications. Depending on the type of composition may include:

1. Some types of natural and organic resins.
2. Synthetic plasticizers.
3. Natural rubber and active astringent additives.

These mixtures, when used, do not release harmful substances and maintain chemical neutrality. In addition, the most popular mastic waterproofing 24 contains special components that provide the material with antiseptic and herbicidal properties. Thanks to all additives, it is durable, elastic and resistant to environmental influences. Depending on the drying time, bituminous rubber mastic is:

1. Not drying out. Liquid, globular, non-drying mixtures can remain in the gelatinous state for a long time ..
2. Quick-drying. This mixture hardens in a short time, taking the necessary form.
3. Drying. This mastic represents an average state between a non-drying and a quick-drying one.

Also, this material is subdivided according to the characteristics of the reaction to the mechanical action. Mastic waterproofing can be:

1. Elastic.
2. Plastic or hard.

The consumption of bitumen mastic depends on its type. Due to its excellent astringent properties and the ability to reliably adhere to other materials, the waterproofing easily fits into any, whether horizontal or vertical joint.

Process of surface treatment with waterproofing mastic

Before applying the waterproofing material, it must be thoroughly mixed to a homogeneous mass. When solidifying, add solvent to the mixture. Keep the building material in a closed container and in a warm place.

When mastic is applied waterproofing "TECHNONICOL" 24, any substrate should be cleaned of dust, dirt, grease, ice. And more: before you start laying the waterproofing, the surface must be primed, that is, treated with a special primer. Especially it concerns a porous surface. In the case where the mastic is applied to the metal parts of the structure, they are recommended to be cleaned of rust and treated with a solution against its formation. The surface for applying the waterproofing material must be dry, if necessary, it is dried further.

Features of work with mastic

During installation, the room must be ventilated. Also, during operation, the use of an open fire is not allowed, since bitumen mastic is a combustible material and is rapidly flammable. If the outside temperature is minus, the mastic waterproofing needs to be heated. It is applied by layers with the help of brushes, rollers, sprayers. It is advisable to make two layers along and across. Approximate time for drying each is 6-9 hours. It is also possible to pour a waterproofing agent over the surface and then level it up using a rake. The average time for complete drying and curing of the mixture, as well as a set of all necessary properties, is 7 days. Approximate consumption of bituminous waterproofing 1 kg per 1 sq. Km. M. Of the surface.

The excellent quality of waterproofing mastics, its high environmental friendliness, simplicity of laying are appreciated by most professionals in the field of construction, so it is so popular among experienced masters.
