Mastic tiokolovaya: properties, features of application and storage

When building prefabricated industrial or residential buildings, it is extremely necessary to use special materials to seal joints between individual structural elements. Why use sealants? Joints - the most vulnerable place of any structure, because through them can penetrate into the moisture. This threatens to accelerate the corrosion of welded parts, which can reduce the service life of the building, and quite significantly. The industry produces many kinds of substances to seal joints. One of them is mastic tiokolovaya AM 0 5.

Properties of mastic

This is called a composition of several components, the basis of which is synthetic rubber. At normal temperature, the substance solidifies to a rubber-like elastic material. Since the sealant does not contain solvents, after curing it does not shrink, so there are no crevices, and joints are reliably protected from penetration of moisture.

The material has excellent adhesion with almost all building materials: brick, metal, wood, concrete, plaster and others.

Among the most important characteristics that a thiocolide sealant has, high resistance to impacts:

1. Heat.
2. Shrinkage deformations.
3. Low temperatures.
4. Ultraviolet.
5. Infrared radiation.

Thanks to this, it is possible to use the material in any climatic zone of the CIS countries and Russia.

Requirements for sealants

Regardless of the location of the joint, the sealing material used must:

1. Maintain all its characteristics in all weather conditions.
2. Keep your properties for a long time.
3. Protect the joints from water.
4. Do not allow air to pass more than prescribed by the standard.
5. Do not react to various aggressive substances (alkalis, acids).

And, of course, one of the important characteristics for consumers that mastic tiokolovaya should have is price. Today it remains quite affordable and is in the range of 210-230 rubles. For 1 kg depending on the region.

As can be seen from the listed requirements, the material for sealing should have such properties that are not presented any more to any other building material.

Application area

Sealing mastic is used during repair or erection of new structures for:

1. Protection of all nodes of conjugation of building structures from moisture.
2. Sealing joints that are located on a false balcony or a trough roof.
3. Sealing of metal elements adjacent to the wall of brick, to the roof, the attic.
4. Sealing inter-block, inter-panel and other types of joints that protect the outer walls.
5. Waterproofing protection of construction seams.

Application Features

Thiokal sealant is a set of two pastes. One of them is curing, the other is basic. Before you start using the material, you need to prepare it. To do this, it is necessary to knead well the curing paste and then introduce it into the main component in the amount indicated in the instructions. Mix the substance until both components are mixed well, and there will be no color divorce. But it is necessary to prepare the sealant before the application, otherwise the substance will harden before it is used, - the mastic remains viable from one to 15 hours. The setting time depends on the ambient temperature. Completely the process of vulcanization will end within 6-10 days. But if the ambient temperature is below zero, the hardening process slows down and completely stops at -40 ° C.

To accelerate the vulcanization of sealed joints, they can be heated. The process will be completed in just 12-16 hours if the heating temperature is 80 degrees, and at 50 degrees the hardening will end in 26-36 hours.

Before applying the sealant, you need to prepare the surface - to clean it from ice, debris, dirt. Apply mastic tiokolovaya only on dry surfaces. If moisture is present, it must be wiped with a rag. The thickness of the layer can be from 2 to 5 mm. Depending on how wide the seam is, about 100-300 g of sealant can leave the running meter. If it rains, snow, and work is necessary on the street, then surface processing is prohibited.

Apply mastic tiokolovaya very easily with a brush, spatula, syringe. In the bottom of the slots, the agent can simply be poured and, if necessary, leveled with a spatula. Manufacturers guarantee a minimum service life of the material - from 10 years and above: it depends on the aggressiveness of the environment.

An important detail: during the preparation of mastic is forbidden to use any solvents.

Storage and transportation

For sale sealing mastic in metal boxes, drums of printed cardboard or any other container. The main requirement for it - it must be airtight and wide-necked. Pre-paste is packed in a bag of polyethylene and only then placed in a tare box. Its weight is 30 or 75 kg. The material can be stored indoors, which is well ventilated, or under a canopy to protect from direct sun rays and prevent moisture from entering. Since the sealant is not afraid of high and low temperatures, it can be stored outdoors at any time of the year, but not more than 6 months.

If the mica tiokolovaya is stored outdoors and the temperature rises above +30 ^о С or falls below -20 ^о С, the material must be protected or transferred to a room more adapted for storage.

Transportation sealant can be in any form of transport, because it is a non-hazardous substance.

Security measures

Although mastic tiokolovaya is not a dangerous substance, it is still necessary to observe some precautions:

1. Get down to work just by wearing rubber gloves.
2. Avoid direct contact with the skin surface.

If the material is exposed to unprotected skin, it should be removed using ethyl alcohol. After this, wash the surface of the skin with soap.
