Liquid rubber is a modified bitumen-latex emulsion, which includes two mutually insoluble liquids - water and bitumen. As a result of surface treatment with such material, a seamless monolithic coating is formed, which will be impenetrable for water, ice and snow. In addition, this coating is resistant to mechanical damage and various temperature chemicals, as well as to ultraviolet radiation.

Features of the material

The name of this substance does not quite reflect its essence and is somewhat incorrect. This mass has visually similar to rubber properties: black color, dragging consistency, waterproof quality. On this similarity ends. If the basis of rubber is rubber, the basis of this material is a bitumen. The popularity of the "Liquid Rubber" name is explained by the convenience of the consumer. From the creators of this substance, a proposal was made to introduce the name "seamless sprayed waterproofing", but it did not find support because it is too difficult to perceive the consumer.

Liquid rubber as a waterproofing material has a wide range of use:

1. Through this substance, insulation is carried out from the receipt of moisture of the roof, the foundation, inter-storey floors, basements, pools, wells, metal and concrete tanks, etc.
2. It is recommended to use such rubber for surfaces having a large amount of adjoints. In this case, rolled materials will be unsuitable.
3. Due to the high resistance to vibrations, liquid rubber can be used for waterproofing the roof having ventilation outputs.

Application area

Consider the quality of the waterproofing layer of liquid rubber on some examples. The strength and durability of the entire structure depends on the qualitatively completed foundation. Therefore, it is important that the layer of waterproofing of this part of the building prevented the seeping of groundwater. The waterproofing of the foundation includes comprehensive actions involving the coating of rubber on the foundation plates and walls. As a result of the use of liquid rubber, the waterproofing coating of the foundation will not be damaged as a result of the "shrinkage", and high hydrostructory indicators will make it possible to create reliable and durable protection of the foundation of the building.

Outdoor coating also needs waterproofing. This creates the protection of the floor from mold, fungus, dampness and destruction. Liquid rubber allows you to get a comfortable coating with a long service life, which for a long period does not require repair. In this case, the waterproofing layer can be a finish decorative coating and the basis for a different type of coatings, such as laminate, tile, screed, mosaic, etc.

Varieties of liquid rubber

The categories of liquid rubber distinguish:

• one-component rubber - represents a liquid mass, fully prepared for use and having a wide variety of shades;
• two-component rubber - includes two components: the main component and hardener.

Also, this material can be classified according to the following types:

1. Sprayed rubber, the application of which occurs by the method of cold spraying by means of special equipment RX-27. This method of base treatment is characterized by a high speed of work and high quality quality indicators. Liquid rubber, which can be used in any construction supermarket, is a classic version of the waterproofing material and occupies a leading position among similar compositions.
2. Painting rubber involves applying materials forming a film and having a liquid or pasty consistency. The process of application is carried out manually with spatulas, brushes and painting brushes.
3. Bulk liquid rubber, the price of which will be less than the other analogues. In this case, its manufacture occurs immediately before waterproofing.

Benefits and disadvantages of material

1. As a result of applying liquid rubber to the surface after its drying, a seamless monolithic coating is formed that does not have a single joint.
2. This waterproofing material has a high adhesion indicator relative to all building materials - wood, concrete, metal.
3. At the time of application by spraying, rubber fills all the pores and microcracks of the base, due to which a good clutch is ensured.
4. Liquid rubber has elasticity, that is, the ability to increase in the amount and return to its original position. Thanks to this quality, the coating will not be damaged as a result of the effect of high and low temperatures.
5. In the summer, the volume of rubber increases, and in winter it decreases. Thus, if the coating is made of a material that does not have elasticity properties, after a certain period of time, cracks may appear on its surface.
6. A layer of waterproofing liquid rubber is distinguished by uniformity and reliability. This effect is achieved thanks to the method of application excluding skipping, since during operation, the base is processed at least two layers of the composition.
7. For coating applies, a mechanized method is used, as a result of which all protruding elements are processed, such as antennas, caps, pipes, etc.
8. The speed of surface treatment with liquid rubber is high enough. Subject to the use of professional equipment two people can perform for two days with waterproofing 800 m ² Roof. For comparison, you can bring the following example. A similar amount of work when using rolled materials is performed in 14 days.
9. Liquid rubber does not represent health hazards, since it does not contain toxic components.
10. An important advantage of this substance is its multifunctionality, since the possibility of its use is not limited to the performance of waterproofing.
11. After treatment with liquid rubber, the surface is suitable for applying different finish coatings. This is quite convenient, in particular when roof waterproofing, as it turns into a useful area and becomes suitable for further operation.
12. This waterproofing material has a wide color gamut. In the event of damage to the waterproofing coating, its recovery does not require significant labor and time costs. To eliminate damage, there will be a local processing of the damaged place.

Despite such a number of positive properties, this material is not devoid of flaws. Among the main factors, you can select the following:

• high cost of necessary equipment and work;
• expensive materials.

Application technology

Application of liquid rubber is made on the basis using a mobile device that dispensing and mixes the composition. This equipment functions using a gasoline engine. This is quite convenient because there is no need for electricity supply. In stock Devices There are 150 m hoses. This makes it possible to carry out work in the most hard-to-reach places.

The procedure for coating liquid rubber involves three stages.

1. The first stage is to prepare the surface. To prepare a reason for the workflow properly, it is necessary to remove all existing pollution from the surface: dust, fat stains, extraneous deposits. To achieve the desired result, perform the purification of the base using the hydraulic installation. After that, it is necessary to wait a day so that the surface is dried.
2. The second stage of the work is called prime. Its essence consists in spraying the first layer of waterproofing material on a pre-prepared basis. The quality of application of this layer determines the efficiency of waterproofing and the duration of its operation. The privacy task is to be completely removed from the surface of the remnants of contaminants. During the hydrodynamic cleaning performed at the first stage, small dust particles remain on the surface, which are removed using the intestine. Due to this, the adhesion of liquid rubber in relation to the base is significantly improved.
3. The third final stage involves applying a waterproofing layer of liquid rubber. To ensure uniform application of this layer, the spraying must be performed perpendicular to the surface. The distance between the working surface and the sprayer must be at least 40 cm. Components included in the coating are mixed during spraying. These are such components as components A, B, as well as CACL and PREMIER RUBBER MEMBRANE SYSTEM.

Consumption of liquid rubber when processing 1 m ² It is 3 liters when applying a layer of 2 mm. The polymerization of the waterproofing layer is carried out for 72 hours with air humidity of 50% and a temperature of 20 ° C. During the period of the polymerization process, the first days after spraying on the insulating layer appear drop-down water drops. This occurs as a result of the effects of the catalyst.

Recommendations for storage

1. Liquid rubber during the storage period and before spraying needs careful stirring.
2. The component "A" when stored must be mixed once every month. When performing this procedure, the temperature of the composition should be at least 15 ° C.
3. Stirring is made by a mechanized manner using a mixer whose rotational speed during the procedure should be 100 revolutions per minute.
4. Before applying to the working base, the mass mixing must be performed within 60 minutes.

Conclusion

Performing isolation from the receipt of moisture by means of liquid rubber, as a result we obtain a solid, durable, elastic, seamless coating. It has a long operating period, resistant to different impacts and is environmentally friendly. Consumer reviews liquid rubber is an optimal option for waterproofing bearing structures.

The application process differs relatively high speed, and special equipment allows you to apply the composition in hard-to-reach places.
