Bulk coating is becoming popular in the construction market. It is easy to explain such a phenomenon: thanks to good technical characteristics, people are increasingly using liquid rubber as a waterproofing material, since it will protect the building well from negative atmospheric influences (rain, snow and strong wind). The article will discuss the technological process of the device of the bulk roof and the manufacturers of this material are mentioned.
general information
Bulk (mastic) roof - a waterproofing material, which consists of bitumen, latex and technological additives mixed with water. After application, the liquid instantly turns into a continuous layer, which will not allow moisture to pass through, and in appearance it resembles rubber. Technical properties of the material are maintained under the influence of high and low temperatures. A solid roof can withstand temperatures from -50 to +120 ° C.
The surfaces of any roofs are treated with material: their shapes and sizes do not matter in this case, since the liquid will be distributed over the entire coating area, and after that it will become solid. Do not forget: the wider the site, the faster the waterproofing work will be completed. The presence of visors and chimneys is also not a problem, since all parts of the roof are processed with material.
Scope of application
The use of a liquid roof for waterproofing works is a popular event, 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 cold and in a heated state.
Liquid bulk roofing is used when installing roofs made of such materials:
- slate;
- roof tiles;
- corrugated board;
- reinforced concrete;
- tree.
The application technology, depending on the type of coating, is practically the same.
Self-leveling roof: advantages and disadvantages
You 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;
- it will only be possible to dismantle the material mechanically;
- the high price of the apparatus, with the help of which work is underway on the installation of a liquid roof (above 100,000 rubles).
However, there is one good tip: rent such a device in order to significantly reduce financial costs.
The advantages of this waterproofing material are greater, namely:
- high elasticity;
- long operational period;
- the final coating will be solid - no seams, cracks and holes;
- on 1 m 2 of the roof you will need to use a minimum of 1-3 kg of material;
- the sun's rays will not damage the liquid roof;
- the material adheres perfectly to any coating;
- high waterproofing properties;
- the material is not afraid of precipitation, high and low temperatures;
- harmlessness.
In addition, after completion of installation, the bulk roof becomes extremely resistant - it is not afraid of mechanical damage. There are three methods of surface treatment using this material: sprayed, stained and bulk. It is worth describing each of the methods in detail.
Spray technology
The organization of the bulk roof according to this technology consists in the fact that the composition will have to be sprayed with the help of a special apparatus that can work both from electricity and from liquid fuel. The mechanical device will need to be connected to two containers, in the first of which there will be an emulsion (bitumen-polymer), and in the second - calcium chloride, which will provide quick hardening of the liquid waterproofing material. During the operation of the apparatus, substances will pass through one nozzle, and after that they will be fixed on the roof surface, creating a polymer-bitumen membrane.
It is recommended to use spraying technology if it is necessary to waterproof flat or inclined surfaces, since the mixture is evenly distributed over the roof of the building. In addition, experts argue: the material should be sprayed only if it is necessary to process a large area, since only in this way can save liquid.
The device is purchased at a hardware store or it can be rented. You need to know: a mechanical device is expensive, so you have to pay a large sum of money.
Staining technology
The main feature of this method is that you will have to process the roof surface manually, but, in addition, you must first apply a primer layer to the roof. When the preliminary measures are completed, you can begin waterproofing work: you will have to use a liquid mixture and water. The composition is recommended to be applied to the surface using a paint roller. The first layer will dry in an hour - this indicator will increase if the air temperature is less than +20 ° C. When it is cold outside, you will need to wait 2-3 hours for the material to completely harden.
The next layer of the bulk roof is made from a solution without adding water. The thickness of the second layer of waterproofing material is 3 mm. Work must be carried out in compliance with this technique: apply the composition across the first layer. It is recommended to level the liquid coating with a spatula.
If you apply the method of coloring, then you can not only protect the building from atmospheric precipitation, but also decorate the roof.
Bulk technology
In this case, you will have to carry out the work manually. First, the roof surface must be prepared: treat the base with a bitumen composition, and then with a primer. If you complete the initial steps correctly, you will end up with a layer whose thickness should be 10-20 mm.
When working with bulk technology, the roof should be treated with liquid material, and a layer with a thickness of 20-30 mm should be formed. To make the layer 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 to apply another layer of waterproofing material over the hardened mixture to completely protect the building from moisture.
As a rule, 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 high-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, therefore it is popular in the construction market. If during the work the spraying technology is chosen, then it is necessary to mix the composition with calcium chloride in a ratio of 1: 8, respectively. The service life of this liquid rubber is 20 years.
Buyers of the water-emulsion mixture claim that the Technonikol bituminous-latex mastic for the self-leveling roof 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 the Technoprok company
This is a water-based bitumen-polymer bulk roof. If you need to process a large area, 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 works were satisfied with the quality of the building material. They claim that liquid rubber from the Technoprok company has a low cost, is safe and has high elasticity. For 1 m², 3.3 kg of the mixture is consumed, and its minimum price for 1 kg is 115 rubles.
Liquid roof "LKM USSR"
The material is used both to repair damaged coatings and to protect the roof from the negative effects of high humidity. The key advantage of this self-leveling roof is that the work can be carried out manually or with the help of special mechanized equipment. Liquid rubber from the company "LKM USSR" - a material with high technical characteristics. In addition, the composition can treat any surface.
Many buyers leave positive reviews regarding bulk roofs from this manufacturer. For example, some of the consumers claim that it is a strong and durable material that is securely laid on the base. Some people even apply the composition to the old roofing material, and as a result, an elastic layer is obtained that protects the building from moisture. Buyers note that the liquid roof is well placed on both metal and bitumen.
This liquid rubber will last about 25 years. 1.1 kg of the mixture is consumed per 1 m², and its cost per 1 kg is 275 rubles.
Liquid waterproofing "Euromast Plus"
In the construction industry, there is an opinion that this mixture is one of the best mastics on a bitumen basis. Professionals lay this material on the surface using an airless spray machine. Euromast Plus liquid rubber is resistant to wear and does not deteriorate from exposure to sunlight, so its service life is about 25 years.
If you need to write an abstract on the construction of bulk roofs, it is recommended to describe the material from this manufacturer, since buyers respond positively about this mixture. Some of the consumers say that it is best to use Euromast Plus liquid rubber on concrete roofs. Professionals note: the high adhesion and elasticity of this material allow work on deformed and uneven sections of the roof. 3.6 kg of mixture are consumed per 1 m², and its cost per 1 kg is 120 rubles.
Everyone will be able to personally choose from which to perform a bulk roof by reading this material.
