Local coating is becoming popular in the construction market. It is easy to explain this phenomenon: due to good technical characteristics, people are increasingly using liquid rubber as a waterproofing material, since it will well protect the building from negative atmospheric influences (rain, snow and strong winds). The article will discuss the technological process of the self-leveling roof and mention the manufacturers of this material.
Liquid (mastic) roofing is a waterproofing material that consists of bitumen, latex and technological additives mixed with water. After application, the liquid instantly turns into a continuous layer that will not let moisture through, and in appearance it resembles rubber. The technical properties of the material are preserved under the influence of high and low temperatures. The frozen self-leveling roof can withstand temperatures from -50 to +120 °C.
The material is used to process the surfaces of any roofs: their shapes and sizes in this case are notare important, since the liquid will be distributed over the entire area of \u200b\u200bthe coating, and then it will take on a solid form. Do not forget: the wider the site, the faster the waterproofing work will be completed. The presence of peaks and chimneys is also not a problem, since all sections of the roof are processed with the material.
Scope of application
Using liquid roofing for waterproofing is a popular undertaking because it sticks to any surface. Therefore, it is not surprising that the scope of the material is very wide, moreover, it is easy to work with it both in a cold and heated state.
Liquid bulk roofing is used when constructing roofs from the following materials:
- corrugated board;
- reinforced concrete;
The application technology, depending on the type of coating, is practically the same.
Local roofing: advantages and disadvantages
We should start with the negative qualities of the material, which include the following points:
- work can only be carried out at temperatures above +5 °C;
- material can only be dismantled mechanically;
- high price of the apparatus with which work is being done on the installation of a liquid roof (above 100,000 rubles).
However, there is one good tip: rent a similar device to significantly reduce financial costs.
The advantages of this waterproofing materialmore, namely:
- high elasticity;
- long operating period;
- final coating will be continuous - no seams, cracks or holes;
- per 1 m2 roofs will need to use a minimum of 1-3 kg of material;
- the sun's rays will not damage the liquid roof;
- material adheres perfectly to any coating;
- high waterproofing properties;
- material is not afraid of precipitation, high and low temperatures;
Besides this, after the installation is completed, the self-leveling roof becomes extremely resistant - it is not afraid of mechanical damage. There are three methods of surface treatment with this material: spraying, painting and pouring. It is worth describing in detail each of the methods.
The organization of the self-leveling roof using this technology lies in the fact that the composition will have to be sprayed using a special apparatus that can operate both from electricity and from liquid fuel. The mechanical device will need to be connected to two containers, the first of which will contain an emulsion (bitumen-polymer), and the second will contain calcium chloride, which will ensure rapid hardening of the liquid waterproofing material. During the operation of the apparatus, the substances will pass through one nozzle, and then they will be fixed on the roof surface, thus creating a polymer-bitumen membrane.
It is recommended to use sputtering technology if you need to carry outwaterproofing of flat or inclined surfaces, since the mixture is evenly distributed over the roof of the building. In addition, experts say: the material should be sprayed only if it is necessary to process a large area, since this is the only way to save liquid.
The device is purchased at a hardware store or it can be rented. Need to know: A mechanical device is expensive, so you will have to shell out a large sum of money.
The main feature of this method is that you will have to process the roof surface manually, but, in addition, a primer layer must first be applied to the roof. When the preliminary measures are completed, you can start waterproofing work: you will have to use a liquid mixture and water. The composition is recommended to be applied to the surface with a paint roller. The first layer will dry in an hour - this figure will increase if the air temperature is less than +20 ° C. When it is cold outside, it will take 2-3 hours for the material to fully cure.
The next layer of self-leveling roofing is made from mortar without adding water. The thickness of the second layer of waterproofing material is 3 mm. Work must be carried out in compliance with the following technique: apply the composition across the first layer. It is recommended to level the liquid coating with a spatula.
If you apply the staining method, you can not only protect the building from precipitation, but also decorate the roof.
In this case, you will have to carry out the work manually. First, the roof surface must be prepared: treat the base with a bituminous compound, and then with a primer. If you follow the initial steps correctly, you will end up with a layer whose thickness should be 10-20 mm.
When carrying out work using bulk technology, the roof should be treated with a liquid material, and a layer 20-30 mm thick should be formed. In order for the layer to be smooth and even, it must be rolled out on the roof surface using a wide paint roller (it is recommended to use a tool with a long handle). Experts advise applying another layer of waterproofing material on top of the hardened mixture to completely protect the building from moisture penetration.
Usually, the liquid dries instantly, but it is recommended to wait a little before applying the second layer. In addition, this technology is not used if it is necessary to perform a bulk roof on a roof with a large slope.
TechnoNIKOL - a brand of quality mastic
This is a water-emulsion mixture, which includes additives of polymers and latex. Mastic "TechnoNIKOL" does not tear when the base is deformed, so it is popular in the construction market. If spraying technology is chosen during work, then the composition will have to be mixed with calcium chloride in a ratio of 1: 8, respectively. The service life of this liquid rubber is 20 years.
Buyerswater-emulsion mixture claim that TechnoNIKOL bitumen-latex mastic for self-leveling roofing has high technical qualities, moreover, it is strong and durable. 4 kg of liquid rubber is consumed per 1 m², and its cost per 1 kg is 150 rubles.
Mastic from Technoprok
This is a water-based bitumen-polymer self-leveling roof. If you need to process a large area, then it is recommended to use this material. A waterproofing layer made from this mixture will last 10 years. Liquid rubber from the Technoprok company instantly hardens and forms a reliable sound and waterproof layer.
People who used this mastic during waterproofing work were satisfied with the quality of the building material. They argue that liquid rubber from Technoprok is low cost, safe and highly elastic. 3.3 kg of the mixture is consumed per 1 m², and its minimum price for 1 kg is 115 rubles
