Distinctive feature such a relatively new material as liquid rubber is the absence in the composition of any solvents. Thus, during operation, no harmful volatile organic compounds are released, and the coating is relatively safe and has a high level of waterproofing performance. Along with the usual type of rubber, the liquid material has a black coloration and has good elasticity, as well as many advantages.
The water base and emulsion based on modified bitumen are supplemented with certain proportions of elastomers, polymers and catalysts in the form of a calcium chloride solution, which gives the liquid rubber unique physical and chemical properties:
Conditional disadvantages of liquid rubber are represented by the need to use a special installation in the application process. However, the cost of such a unit is fully justified when performing a large amount of work and is characterized by a quick payback.
The method of applying liquid rubber determines the classification of this relatively new and promising waterproofing material:
Immediately after priming, a layer of liquid rubber is poured onto the base, which must be distributed as evenly as possible with special rollers. The standard layer thickness is about three millimeters. After curing for five to seven minutes, a second or final potting coat is applied.
Despite obtaining the most even processed surface, this method is not applicable to pitched roofs.
An option for high-quality waterproofing of flat roofs.
The standard drying time is two days. This method is used for processing small pitched surfaces and, if it is inappropriate to use mechanical equipment.
Priming is the process of applying a thin layer of liquid rubber, represented by component "A", which involves obtaining reliable adhesion of the material to the base and removing dust microparticles.
This process belongs to the category of simple work, which involves high-quality spraying of two types of liquid. One of the liquids is an activator, and the second is a bitumen-polymer emulsion.
When sprayed, the liquids mix to form a homogeneous composition in the form of liquid rubber. When dry, the treated base acquires a black color, which indicates the correct application and the formation of a high-quality seamless membrane.
Small surfaces can be covered with liquid rubber independently, without the involvement of professionals and the use of special equipment. To perform high-quality work, you need to correctly carry out the calculation.
For based on liquid rubber, an indicator of the functional load of the roof is taken into account. When calculating, the following indicators are taken as a basis:
To apply the composition, a special airless apparatus is most often used.... This type of airless equipment for spraying liquid rubber belongs to the category of universal devices powered by gasoline or an electric drive.
The main condition is a high-quality and thoroughly prepared surface, which is pre-cleaned of debris and dust.
Small cracks and minor defects are closed with liquid rubber during application.
The spraying method involves the use of special equipment and refers to mechanical coating methods. Liquid rubber is sprayed onto a carefully prepared surface by means of a special installation that is connected to a container with a polymer-bitumen emulsion and a container with a calcium chloride hardener.
Two components getting into the nozzle are mixed and sprayed, which makes it possible to obtain a bitumen-polymer waterproofing membrane with a thickness of two to four millimeters on the base to be treated.

Summing up
For installation, especially if necessary, treat large areas or structures with a complex configuration, it is advisable to use the application of a bitumen-polymer two-component water-based emulsion.
A definite advantage of the mechanized method of application by the method of cold spraying is the formation of a monolithic seamless membrane without abutments and joints, regardless of the configuration and shape of the surface.
The relevance of using liquid rubber in conditions of vertical surfaces is due to the non-flowability of the material even at high temperature indicators.
If you've ever heard of so-called liquid rubber before, you're probably wondering how far technology has come. This material is difficult to replace when it comes to difficult terrain, where it is generally impossible to use roll materials... It is also great for arranging new structures and repairing old ones, as well as protecting important structural elements from corrosion. At the molecular level, this material is capable of adhering to almost any surface!
But waterproofing the roof with liquid rubber only at first glance seems to be a simple and straightforward process. In fact, in order to get really high-quality waterproofing in the end, you will have to strictly follow all the rules! And we will tell you all the details and nuances of the process itself.
Over time, improving construction technologies, more and more serious requirements are imposed on roofing waterproofing materials: high properties and convenience in carrying out the work themselves. This is especially true for the processing of a roof with a complex relief and atypical building material, which today is not at all uncommon.
Depending on what type of liquid rubber you will be using, you will need special equipment, or you can get by with a regular bucket and roller.
For a one-component solution, a brush and normal hand application are sufficient. After all, such rubber is no different in consistency from ordinary mastic. But two-component rubber can be sprayed only with the help of special mechanized equipment.
This is an airless spraying unit in which two components are supplied and mixed at once under pressure. Once in the open air, they quickly polymerize. And as a result, they have excellent adhesion without a single seam.
As a result, spraying liquid rubber with the help of special equipment, the whole work turns into a rather simple and pleasant process:
The process of spraying the roof covering itself is quite interesting. What other roof could you apply this way, and so quickly? Moreover, even the most difficult task is easily handled by only two employees.
Special equipment helps to achieve the exact thickness of the application, no more and no less. This is very important, because liquid rubber is not a cheap material. The principle of such a unit practically does not differ from the operation of a conventional spray gun.
It contains two tanks, one of which contains a polymer-bitumen emulsion, and the other contains a calcium chloride hardener. Both substances are supplied from containers under pressure, the components are mixed in the tip and fed through a small hole - thin enough for the coating to be from 2.2 to 4.0 mm thick. Already in place, the components act on each other and freeze under the open sky.
Moreover, the method of spraying under pressure is significantly different from pneumatic. The loss of material to the environment is noticeably reduced here. In simple terms, fog does not form around the sprayer, and less solvent is introduced into the composition itself.
Thanks to all this, when working with liquid rubber, it is not necessary to wear a protective suit and mask, and the speed of the coating itself is much higher, because all the material is directed strictly towards the roof, and not into the air. And all the equipment for the work of one team easily fits into small car by the type of "Gazelle": catalyst, liquid rubber and installation.
Most often, liquid rubber is black, but the material itself is compatible with organic silicon or water based, but not with chemical solvents. But today many types of colored liquid rubber are produced, but you can also paint your roof yourself with a special paint VD-AK-1503 for this venture, which can also be released from a spray bottle. And this has another plus - additional protection liquid rubber from ultraviolet radiation:
Experienced roofers are able to work with two types of color at once, applying one layer first, and the second on top of it. What is it for? It's not about design at all!
It is just so clearly visible how well the new layer was sprayed, and whether it completely covered the previous one, or some places were still missing. In addition, when spraying a top layer of a different color, you can clearly see how well the base material diverges.
But, when hiring a team for such work, keep in mind that you need to have a license to cover the roof with liquid rubber, because without personnel training it is impossible to spray such a coating with high quality, and there are pitfalls in the process.
Depending on the task, the required section of the roof is covered with liquid rubber with a thickness of 2 to 3 mm. At the same time, the coating has high elasticity and a wide temperature range from -45 ° C to + 120 ° C. And the quality of liquid rubber depends on how smooth it will lie on the roof and how quickly it will harden.
First, you should prepare the surface, seal up all the pits, chips and cracks. Ideal if you can clean the roof of dirt well, for which water from a hose under pressure and detergent if you have the opportunity. And how smooth the surface is will affect the uniformity of rubber application:
Also, the corners of the joint with the wall and the exit of the roofing elements are pre-treated with a primer and even mastic:
Then use a roller to spread the composition over the roof surface. Once the first coat dries within 8-24 hours, apply the second coat.
The main thing is to carefully distribute the material over the entire surface:
Freshly applied rubber hardens instantly to 80%, and continues to harden for another 48 hours, although it is already waterproof. Although after 10 minutes you can safely walk on such a roof.
As a first step, calculate the amount of liquid roof rubber needed. So, for a layer of 1 mm per square meter, you will need from 1.35 to 1.65 kg of liquid. Also, a lot here depends on the material of the base on which the liquid rubber will be applied:
Make an accurate calculation, and you will acquire not much and not enough. Moreover, liquid rubber is not a cheap material.
Liquid roofing rubber is one of the best materials for waterproofing and repairing. Indeed, in addition to the fact that such a coating creates excellent hydro and sound insulation, liquid rubber itself helps to strengthen the roof structure.
Liquid rubber can be applied directly to old layers of roofing felt roofs, without prior installation. For which the material itself is appreciated, because it can be laid on old roofs. The only thing is that then deflectors are installed on the old surface to remove the accumulated moisture.
For local repair and waterproofing of the roof, one-component liquid rubber is more suitable for you, because it can be applied with a roller or brush. And at the same time, the final quality will be no worse than that of the two-component! First you need to prepare the liquid rubber by stirring it well. Now use special paper or fabric pads to give the repaired surface more rigidity and a kind of reinforcement.
This is how the process of waterproofing with liquid rubber looks like in practice. One-component rubber should be applied in two or three layers, with preliminary drying of each of them:
All waterproofing work should be carried out at a temperature of + 5 ° C, spraying or applying rubber exclusively on a dry surface.
If you are worried about the quality of liquid rubber for repair, then use well-known imported materials like Premier Rubber Membrane. This is the composition of the Canadian company Cantex Coatings Ltd, which consists only of non-flammable liquids, without any organic volatile compounds.
You will recognize this product by its dark brown color and dense rubber cover... After complete drying, it will have a particularly high elasticity, about 1500%, absolute water and vapor impermeability and remarkable resistance to mechanical deformation.
At the same time, the repaired place will retain such properties for more than 25 years, according to the manufacturer, and this is with constant contact with water:
For comparison: liquid rubber applied to the repaired area in two layers (this is up to 2 mm), according to the waterproofing properties, four layers of roofing material!
But there are some limitations in working with liquid rubber. For example, it is not allowed:
All other weather factors will not interfere with the process. A fascinating process, isn't it?
waterproofing with liquid rubber
The relevance of the search for new solutions in the field of creating reliable roof waterproofing systems has not been reduced, despite the presence of large selection roll coatings. The main requirements for products used for roof insulation are highly effective protection against moisture, maintaining functionality even in difficult climates, environmental friendliness of building materials and an acceptable price. Liquid rubber complies with such characteristics, its use in waterproofing and performance will be considered further.
What are the types, installation diagram, photo and video instructions.
Liquid waterproofing is in great demand today when arranging reliable waterproofing systems. There are a number of advantages that make the building material stand out in comparison with others:
Manufacturers building materials in this market, they continue to amaze with the creation of new and improvement of existing solutions. Liquid rubber can be attributed to new technology, but its prospects are noted by both amateurs and specialists.
In principle, this name is associated only with convenience for the consumer and external similarity with rubber: color, moisture resistance, elasticity. However, the basis of "seamless sprayed waterproofing" is not rubber, but bitumen. Its properties are enriched by a large amount of latex. Emulsion from these component parts modified.
The prospects for liquid waterproofing are quite wide, since the products of the group under consideration allow the formation of a light, high-quality, seamless coating that is not subject to temperature changes. Difficult surface relief, as well as tight deadlines for work are not a problem if you choose a coating made of liquid rubber.
There are a number of areas in construction where the use of such a material is relevant:
Today, there are two types of seamless sprayed waterproofing:
Another method of differentiating such rubber is the method of applying building material. There are three varieties.
Let's start with the advantages of seamless sprayed waterproofing:
elasticity of liquid rubber coating
Bituminous liquid waterproofing is inherent, like any of its analogues, certain disadvantages. We have listed a huge number of its advantages, but for the sake of objectivity it is necessary to identify the disadvantages. There is one point among them: in order to arrange the waterproofing system in a mechanized way, special equipment is needed, which costs a lot.
Everything! On this, in principle, the shortcomings ended, you can begin the installation of the roof of the building from this universal coating.
There is specialized equipment that is used for spraying liquid seamless waterproofing.
applying liquid rubber
Its preparation is the first thing to do before starting work. Usually a mobile spray gun is used for these purposes. A special dispenser, as well as a mixing device, are included in its mechanism. The engines of such equipment most often run on gasoline rather than electricity. This leads to its maximum mobility. It is not necessary for the device to be necessarily connected to the network. In addition, the atomizer is quite compact. These characteristics allow spraying even in places where access is difficult. Another advantage is that the device is equipped with a special hose, the maximum length of which is up to one hundred and fifty meters. This option makes it possible to arrange roof spraying without lengthy and complicated transportation of equipment around the facility.
An important point: liquid rubber is made from environmentally friendly materials, it does not contain harmful and toxic additives. This makes it possible to produce even internal work without special means provided for the protection of the respiratory organs.
Important:
The first rule to consider before starting work. They need to be done only in summer, or in early autumn, late spring, in general, in warm weather.
Moreover, it is important that you need to choose a dry period. Rains are contraindicated temperature regime below five degrees Celsius.
application of the finished mass of liquid rubber
The first stage is the preparation of the base, on which it is planned to apply a layer of waterproofing. To do this, you need to thoroughly clean the working surface from all kinds of dirt: dust, stains: oily, greasy, foreign deposits. The best option- flush it with a water jet. The powerful pressure of water under good pressure maximizes the efficiency of the preparation plan. The substrate must dry for at least twenty four hours. This method, such as burning, is most suitable for removing greasy stains.
Further, the so-called priming is carried out. For such a step in installing a seamless system, it is important to complete the preparation of the base, and in itself it consists in creating a primary waterproofing layer on this surface. Everything further work, the quality of the final roof covering, its technical indicators directly depend on how well the priming is performed. It should finally rid the field of activity from dust fractions and other contaminants and guarantee maximum adhesion of the liquid rubber layer to the base.
The last step in the algorithm is actually spraying a layer that protects against moisture. It is important that it is applied as evenly as possible. A good trick to achieve this is the perpendicular arrangement of the liquid rubber spray and the base on which the waterproofing system is mounted. It is necessary to strictly observe the mark in the range of forty centimeters between the edge of the mobile spray gun, or its hose, and the working surface, the distance must remain free. The elements of the composition of the solution are mixed precisely during this spraying. 1-1.5 m is the optimal width of the strips with which you need to lay the coating of liquid rubber. Transitions must be done in a cruciform direction.
Traditionally, the material in question on flat roofs mounted in two or even three layers. It is important not to forget about the reinforcement, geotextiles are suitable for this function. Fiberglass can be used similarly.
It has already been said above that liquid rubber is multifunctional and its use is not limited to the creation of waterproofing systems on its basis. With the help of the material, you can repair roof coatings created earlier. Immediately, we note that a complete dismantling of the existing coating is not required. There are two main directions for such a repair:
Repairing problems in the form of a bubbling waterproofing surface is part of the repair work. Where maximum swelling is observed, open up and cover with seamless sprayed waterproofing.
Pay attention to the relationship between roof area and liquid rubber consumption. There are three liters of insulation per meter squared of the surface, while the thickness is two millimeters. If the air temperature is kept at twenty degrees, and its humidity does not exceed 50%, the complete solidification of the finished roof covering should occur three days after spraying. Drops of liquid on the waterproofing after polymerization is a normal phenomenon that occurs due to the operation of the catalyst.
In recent years, liquid rubber, or seamless insulation, has become increasingly popular for roof waterproofing.
It is used to create waterproof, chemical, weather and heat resistant waterproofing coatings on a wide variety of surfaces, regardless of geometric shape and angle of inclination.
Most often, the material is used for flat surfaces. This is due to the large area of objects with a flat roof - up to several thousand square meters. This scale makes the waterproofing process much more difficult.
When using liquid rubber, the picture changes fundamentally: with an increase in the treated area, it becomes easier to carry out work, since this material easily covers even the most complex details of the roof relief: pipes, canopies, various parapets, protrusions.
The big plus of liquid rubber is the possibility of better and faster implementation necessary work than when using roll-up waterproofing materials.
Today, a huge variety of roofing mastics are produced. By composition, they are divided into two main categories:
The first group includes materials that are assembled in the proportion required for application and further hardening.
Multi-component mastic can be represented by several components. It must contain at least two ingredients: a base element and a curing catalyst.
Mastic consisting of two elements are called two-component. Liquid rubber is one of the types of materials in this group.
It should be noted that the title of the material does not convey its essence. This term is erroneous and was chosen for only one reason: it is the most convenient for consumers.
In appearance, this coating resembles rubber: it is black in color, a viscous consistency, and is waterproof. The resemblance to rubber is limited by its appearance. The foundation of this material not rubber, like rubber, but bituminous.
Israeli manufacturers - the creators of this substance - strongly oppose the term "liquid rubber" and propose to call this type of coating seamless sprayed waterproofing. The offer is not accepted because the name is rather complicated for the average consumer: it is bewildering for the majority of potential buyers. This is the reason for using the slightly incompetent but perfectly understandable term “liquid rubber”.
By the way, a material of this type was created in the seventies in the USSR, however, due to the low quality of the bitumen used, it did not become widespread.
Liquid rubber is a cold applied mastic. The basis of the substance is an aqueous emulsion of the polymer-bitumen type.
A distinctive feature of rubber is instant curing. Since it is produced on a water basis, the evaporation of toxic substances is minimized.
Waterproofing seamless coating "Liquid Rubber" not only has a high degree of safety in terms of ecology, but also allows you to cope with construction work in the shortest possible time and provide a durable coating with a long service life.
Some types of mastic are applied by spraying. Thanks to this, joints and seams do not appear. Spraying makes it possible to use rubber for structures of any shape. Since the substance has a low fluidity, it can be used to treat even vertical surfaces.
The material does not deteriorate under the influence of ultraviolet radiation, it retains its qualities in conditions of elevated temperatures.
Depending on the polymer additives used, bitumen, a specific brand and manufacturer, the lowest bending temperature on a bar can be 20 degrees. There are special varieties of liquid rubber, developed for extremely cold regions (for example, Yakutia), they can be used at temperatures up to minus 60 degrees.
Since the bitumen contains essential oils, they can evaporate over time. In this case, a special reaction is observed - bitumen aging effect... This process can be avoided thanks to the polymer contained in the mastic, which creates an anti-evaporation film and prevents aging of the bitumen contained in it. As a result, the service life of this coating is 20 years or more.
Liquid rubber is very elastic (its KPU is over 1000%) and at the same time is durable. Thanks to these qualities, it does not flake off even after sudden changes in temperature, humidity, pressure, surface vibration.
The membrane surface retains its properties even after complete hardening and does not lose them for a long time.
When using liquid rubber, further maintenance of the treated surface can be dispensed with. If necessary, the material can be easily restored and repaired.
The created coating is resistant to mechanical stress, it is fireproof, does not deteriorate under the influence of most construction works chemical substances.
Rubber works well with water-based (solvent-free) paints. This quality allows you to choose a color in accordance with the wishes of the customer.
There are three types of liquid rubber:
- is made and formed directly at the place of waterproofing works.
- installation of waterproofing is carried out by applying liquid and pasty film-forming materials using conventional paint brushes, brushes and spatulas. The work is done manually.
- application is carried out by cold spraying, using special equipment RX-27. This method is distinguished by the ability to quickly perform all work and high quality characteristics of the resulting coating.
Spray-on liquid rubber is the classic option liquid material for waterproofing works, and it occupies one of the first positions among the materials used for waterproofing.
When applying the substance to the surface to be treated, a special spray bottle is used. The material hardens almost instantly. There is no need to preheat the surface, which means that the process is completely fireproof.
Application by spraying allows for an economical use of the substance and a uniform layer. The thickness of the coating should be 2 mm.
When applying the layer, a special mobile dosing and mixing device is used on a gasoline engine weighing 68 kg. The equipment is very convenient to use, since there is no need to supply electricity. It can be operated in hard-to-reach places because it is equipped with 150 meter hoses, so you do not need to move the entire instrument.
Liquid rubber has been tested for compliance with safety regulations.
When working with the material, both in open and in closed rooms, there is no need to use personal protective equipment, since it is odorless and does not emit toxic substances.
Liquid rubber can even be applied to a damp surface, although it is still recommended to pre-dry it.
The application of the mastic is a very easy and quick process. Thanks to its exceptional qualities, it is possible to process up to 2000 sq. meters of surface per day.
Liquid rubber has a number of undeniable advantages:
Among the disadvantages of the material are the following:
Liquid rubber can be used on the following materials:
Liquid rubber is more practical and convenient to use compared to membrane and roll coatings due to the cold application method. It is the most modern method of surface protection. The material is used both in the construction of new facilities and during the repair and reconstruction of old buildings.
The main advantage of liquid rubber is its versatility: since its adhesion to the material occurs at the molecular level, it provides a strong attachment to the material of any quality and texture.
When applying a coating on an old waterproofing, moisture accumulated during the period of use of the old coating is removed using special deflectors. If necessary, it is possible to carry out geotextile reinforcement of the coating.
The use of liquid rubber is very convenient when processing surfaces with a large number of abutments. For such roofs, roll-type materials are simply useless. The high degree of vibration resistance makes it possible to use liquid rubber for roofs with ventilation outlets.
The material provides protection against vibration of the ventilation system, and it does not affect the properties of the insulating material in any way. In addition, rubber reliably insulates joints and abutments from moisture ingress.
The low level of sensitivity to temperature changes makes it advisable to use this mastic in both very cold and extremely hot weather conditions.
Liquid rubber is used on all types of buildings: in the construction or repair of private houses, industrial facilities etc.
Due to its versatile properties, rubber is used not only as a protective coating, but also as an independent roof covering.
When applying liquid roofing rubber, as already mentioned, an airless two-channel metering and mixing element is used.
Work must be carried out at a temperature of at least plus 5 degrees and dry weather. It is best to apply rubber to a clean and dry surface, although it can be sprayed onto wet surfaces.
The roof must be thoroughly cleaned with high pressure water washers prior to application. After that, the surface must be dried. If there are oily stains, they must be removed by burning them out.
Before starting waterproofing, the following measures must be taken:
Liquid rubber is applied to the roof in strips from 1 to 1.5 meters wide. The layer should be uniform, with cross-like transitions. There should be no gaps on the roof surface. In areas where the roof is flat, a slip layer must be included. It is placed between the protective layer and the membrane. It is obtained by laying two layers of geotextile, fiberglass and plastic wrap.
Liquid rubber is often used for waterproofing flat roof... The features of the work are determined by the specific type of roof.
To obtain a waterproofing coating good quality, liquid rubber should be applied on a sufficiently smooth surface. Perhaps the surface will not be perfectly flat - the main thing is the absence of unnecessary items and significant defects on it.
Only under this condition, during the spraying of the material, the layer is distributed evenly and approximately the same height is obtained. The degree of smoothness of the created liquid roof depends on which device was used.
By using a high pressure unit and a sufficiently smooth surface to be coated, a seamless membrane is obtained. In this case, a spraying method is used.
With low pressure devices, the likelihood of a smooth surface is low. Most likely, bumps of different heights will appear on it, which will largely spoil the appearance of the roof. If it is not possible to level the surface before spraying, it should be trimmed with a screed.
When applying liquid rubber to roofing boards, the amount of consumed polymer-bitumen emulsion may increase. If there is a layer of primer, it is necessary, as far as possible, to reinforce all the joints located in the intervals between the insulation plates. It is necessary to put strips of geotextiles in them.
The best way to apply liquid rubber is to coat the screed layer that has already been applied. In this case, it is guaranteed to receive flat surface and attractive appearance roofs.
The cost of liquid roofing rubber is influenced by several factors, the main of which are the specific type of material, its quality characteristics, pricing policy of the manufacturer and the seller.
You can navigate prices based on specific examples.
