Seamless bitumen waterproofing with RESOMIX liquid rubber mastic. Liquid rubber for waterproofing: reviews of application Physical and technical properties of liquid rubber

Waterproofing with liquid rubber- relatively new technology application - cold method spraying This method provides a seamless waterproofing coating that can withstand large linear deformations and movements in structures, maintaining its elasticity even in severe frosts. The composition has excellent adhesion to most building materials, such as brick, concrete, plastic, metal, bitumen rolls and other types of materials. This technology has found its application in the construction and repair of buildings, repair of roofs, basements, foundation walls, as well as reservoirs, ponds, swimming pools, tanks and tanks with drinking water. Sprayable protective membrane completely repeats the shape of the base surfaces, forming a seamless coating of complex geometric shape with linear expansion of up to 800%.

Rubber elasticity reaches 800%

Sprayed waterproofing, liquid rubber is an effective protection of the roofs and foundations of houses and structures from water. Before applying the composition, the surface must be cleaned and thoroughly prepared. Waterproofing coating requires compliance and the right choice The minimum thickness of the sprayed material is 3.0-4.0 mm. It is also possible to additionally reinforce with a layer of geotextile. Geotextiles placed between two layers. There are one-component and two-component liquid rubber, which is not only black, but also colored. IN southern countries The common color of the roof is white (), used in the construction of mastic roofs. White color roofing increases the energy efficiency of the building and reduces the cost of electricity for the air conditioning system in the summer.

The name “liquid rubber” is arbitrary; the name mastic best suits it. The material is resistant to water and UV radiation and is widely used in creating artificial reservoirs and protection of underground structures from water. The most reliable is the building outside the wall. A protective layer is sprayed, which reliably insulates concrete foundation wall from penetration of capillary moisture from outside and inside the room. This method of protecting foundations, walls and underground structures from water allows you to reliably protect these elements of buildings and structures from ground moisture. Moreover, the material can be sprayed onto vertical structures (walls), or horizontal insulation from water can be performed foundation slab or floor screeds in the basement or basement.

Every motorist tries to protect the car as much as possible from all kinds of impacts on the body, because it is one of the most vulnerable places of the car. During operation, body elements are affected by all sorts of negative factors - chemicals, sandblasting, gravel. These negative impacts can ruin the appearance of the car - scratches, abrasions, and chips on the paintwork of the body do not add to its presentability. In addition, they carry a rather serious threat - the possibility of in places where the paint was completely knocked off as a result of an impact, for example, crushed stone bouncing off the wheels. And even if you try to eliminate such a problem in time, there is a possibility that all work was carried out in violation of technology and the process of corrosion formation on the metal will continue even under a layer of paint.

But technology is constantly evolving, and from time to time, means for additional body protection appear on the markets. One of these is, for example, which covers the surface of the body and its attached elements. It is good because it is transparent, that is, it does not affect the appearance of the car at all. But there is also a drawback to this. If the car is not new and there are some defects, or the paint has simply lost its original luster, then the film is no longer suitable for use. And owners of such cars have to look for an alternative method.

Liquid rubber - what is it?

And there is such a way - using liquid rubber for a car. And although this product itself has long been used in the construction field, it migrated to the automotive field not so long ago.

Liquid rubber is a water emulsion consisting of two main components - bitumen and polymer. It has the form of liquid mastic, which is applied using a cold method, and the applied layer hardens very quickly. This product is good because it makes it easy to apply a uniform protective layer even to areas of complex configuration.

You can also find this product in the form of an aerosol, and it is intended for applying protective coatings to small-sized elements.

After being applied to the surface of the car body, liquid rubber forms a thin layer without any joints, which is not only durable, but also quite flexible. This layer provides a protective function. When exposed to external factors, the probability of damage to the coating is very low due to its high plasticity. For example, rebounding crushed stone will leave a small depression on the layer, which will neutralize itself, since the rubber at the point of impact will quickly return to its original shape. This was achieved due to the presence of a polymer in the emulsion, which prevents the evaporation of the components that make the rubber plastic.

Advantages and disadvantages of liquid rubber

Unlike film, liquid rubber is not transparent and is available in different colors, which is achieved by adding different colors to the emulsion. Therefore, this product is applicable to all cars, regardless of the condition of the body paint. The application of liquid rubber provides a layer of a certain color on the surface of the body, so it turns out that the car body is, as it were, painted in a new way, but only with a layer of rubber. At the same time, all previously obtained defects are hidden.

Colors

The polymer-bitumen emulsion does not contain any harmful chemical compounds, since it is made using water based. Therefore, it is applicable not only to the outside of the car, but it can also be used to decorate interior elements.

Rubber is resistant not only to mechanical stress, but also to temperature. It retains its strength and ductility both at low temperatures (at the same time the strength increases) and at high temperatures (becomes more ductile). But temperature does not have any particularly negative impact, other than a slight change in its characteristics.

Liquid rubber has excellent adhesion - the property of sticking to the applied surface. In this case, no special preparation of surfaces is required; it is enough to thoroughly clean them of dirt. Therefore, it can be applied directly to the car's paintwork.

If necessary, the applied layer of rubber can be removed from the surface of the body. And although the adhesion of the emulsion is quite high, it is quite possible to tear it off the body, and the rubber does not “eat” into the paint when applied. Therefore, during its removal, there is no harmful effect on the paintwork; the appearance of the car after removing the rubber remains the same as before its application.

Like any rubber, liquid rubber becomes completely waterproof after hardening. It also resists negative effects quite well. chemicals. Therefore, the surface of the car body covered with a layer of liquid rubber is well protected.

Based on what has been described, we can highlight the main advantages of using liquid rubber on the body:

1. High strength and ductility;
2. Immunity to mechanical, chemical, temperature influences;
3. Updates the appearance of the car;
4. Possibility of easy removal from the surface;
5. Safe to use;

In addition to the positive qualities of liquid rubber for cars, one can include the possibility of experimentation when processing the car body. With the help of bitumen emulsion it is possible to give the surface on which it is applied special kind– matte or glossy color, “chameleon”, etc. Also, when processed, rubber allows you to create different, even complex patterns, which is what this product does good option for performing decorative work on the car body. In this case, it is always possible to remove everything from the body.

The price of liquid rubber is lower compared to other body protection products, which makes this mastic an increasingly popular treatment method.

But bitumen mastic also has disadvantages. It is indicated that the layer applied to the car body does not lose its properties and appearance for a long time. But the practice of using this tool is not quite the same. It is noted that after just a year of use, a whitish coating may form on the surface of the rubber film. It is a consequence of the penetration into the surface layer of elements located in environment– dust, grains of sand, etc. In general, these impurities do not affect the properties of rubber, but they can ruin the appearance of the car, and it is impossible to remove them. To combat this, all that remains is to remove the applied rubber and reapply it.

Where else can you use it?

Now about where else liquid rubber can be used. It was not for nothing that it was mentioned at the beginning that it is also available in the form of an aerosol. Often the product from a spray can is used for the protective and decorative treatment of wheel rims. It can also be used in the interior, for example, to create a covering on the front panel and center console.

The emulsion is additionally used as a sound insulation layer. Liquid rubber is often used to treat wheel arches and. At the same time, the applied layer not only reduces the level of noise in the cabin when driving, it also protects the surfaces from negative impacts and the appearance of corrosion.

The leader among manufacturers of such body treatment products is the American company Plasti Dip. It was with this that the spread of liquid rubber in the automotive sector began. But besides this, there are many manufacturers producing this product - Ribber Paint, Color Dip, Liquid Ribber Coating, etc.

How is it applied to the body?

Note that liquid rubber is relatively easy to apply to the surface of the body. All work takes place in several stages:

1. Preparing the car. Washing the body using cleaning products. Damaged areas on the surface are repaired with a primer, but there is no need to paint such an area; after applying liquid rubber it will not be visible. And this already allows you to save money;
2. Removing and covering elements to which the product will not be applied. Headlights, door handles, license plates, etc. are removed from the car. The same elements that cannot be removed are covered with tape and polyethylene film. The main thing is to completely prevent possible emulsion from getting on them;
3. Applying liquid rubber to all required surfaces. This is done from a distance of 14-17 centimeters in several layers (their number can reach 6-8). The layers dry for 15-20 minutes.
4. Drying the car. After applying all layers, the rubber should completely harden within 24 hours.

Despite the fact that this product is applied in layers, the end result is a uniform protective film on the surface. After all the work, all that remains is to install the removal elements on the car and remove the tape from the windows and mirrors.

As for using the product as sound insulation, the processing process is practically the same. The surfaces of the arches and the bottom are thoroughly cleaned and degreased, after which the required number of layers is applied with a spray gun, followed by drying.

Today, liquid rubber for DIY waterproofing is used more and more often. This material has excellent technical characteristics, boasts a wide range of advantages. Therefore, in our material we will talk about this option for waterproofing various surfaces in more detail. This can be liquid waterproofing for concrete, waterproofing tanks and much more.

Rubber waterproofing is a waterproofing material that has found wide application in a wide variety of areas. So, it is used in automobile production, in the manufacture of shoes, etc. But today we are talking only from the point of view of construction.

This is a new generation material based on bitumen. The composition has an elastic, resilient structure and is characterized by excellent strength. Such liquid waterproofing practically does not peel off from the surfaces on which it was applied. The material is excellent for processing concrete, brick, and other building materials and surfaces.

Rubber liquid waterproofing has another name - polymer- bitumen mastic. In general, bitumen mastic is a close relative of liquid waterproofing.

But still, bitumen mastic for waterproofing is limited in its use and includes slightly different components. The main disadvantage of bitumen mastic is its destruction when exposed to ultraviolet radiation. Therefore, bitumen mastic is not used for exterior finishing.

Advantages and disadvantages

We have determined that bitumen mastic and liquid rubber for waterproofing are somewhat similar, but very different materials. The last one has best properties, technical characteristics. Hence the impressive list of advantages.

1. Waterproofing with liquid rubber ensures reliable connection of various surfaces, regardless of the material used. These can be surfaces made of concrete, steel, wood, etc.
2. Polymer bitumen mastic penetrates deeply into cracks, covers concrete damage, fills them, and ensures tightness.
3. High-quality waterproofing with liquid rubber helps protect against corrosion. This is due to the fact that the applied mastic does not form seams or joints.
4. High elasticity rates guarantee a long service life without loss of original characteristics when waterproofing tanks drinking water, For example.
5. Over time, the mastic does not form ruptures or deform the surface of the waterproofing layer.
6. If bitumen mastic has certain limitations and is a toxic material, then mastic based on liquid rubber does not have these disadvantages. Even when exposed high temperatures on waterproofing rubber, no dangerous fumes are emitted from the composition.
7. It is possible to waterproof a basement made of concrete or brick, or other material, without having to evict residents during the period of work.
8. The material is easy to apply with your own hands. Ceresit brand CR waterproofing has proven itself especially well.

But in order to give an objective assessment of liquid rubber waterproofing, it is necessary to study what disadvantages this mastic is characterized by. Having studied the reviews about liquid rubber, we can say that this is not an ideal material. The disadvantages presented are not significant and in some places controversial, but you should be aware of them.

• To apply liquid rubber, you must use special equipment. Working with them yourself is quite difficult, since there is a potential danger if the application technique is violated. Therefore, it is best to entrust the application of liquid rubber cr 65 to specialists with high level qualifications;
• Liquid waterproofing material based on bitumen is quite expensive. Plus, the services for applying it are far from budget-friendly. The current application price is from $15 per 1 square meter. But the high cost is partly justified by the long service life and wide list of advantages. Moreover, not every customer can afford to shell out such amounts of money;
• To further protect the pool, roof or other surface made of concrete and other materials, paint is applied. But the paint is only suitable on an organosilicon base, the cost of which is very serious;
• The created layer of waterproofing from cr 65 creates a surface that does not have the most attractive appearance. Therefore, cr 65 is used very rarely for private construction.

Methods of waterproofing with rubber

As we have already noted, applying liquid cr 65 rubber with your own hands is not always reasonable or financially justifiable. This is a complex process that is recommended to be entrusted to specialists with appropriate qualifications.

But this does not prevent you from learning about methods of applying the material.

• Airless method. It is used when spraying two-component rubber. To perform such an operation, special equipment is required.
• Under high pressure. Here, appropriate sprayers are used, connected or having built-in compressors. Due to the pressure created, the device supplies the liquid composition ceresite cr 65, cl 51 to the concrete surface.
• Manual method. You can apply liquid rubber with your own hands. But for this, the instructions are first studied, plus only special one-component rubber is used. Other varieties, such as cr 65, cannot be worked by hand.

Areas of application

Today, liquid rubber for organizing waterproofing work on structures and structures made of concrete, brick, silicate, metal and other materials is used in many areas. Including construction and repair work.

1. Structures and containers buried in water. Gradually, large companies are switching to liquid rubber in order to speed up the process and improve the quality of waterproofing concrete and other materials. With proper use of application devices, about 1 thousand square meters of surfaces are processed in 8 hours of work. Due to the instant setting, rubber is not afraid of wet environments.
2. Brickwork. Since liquid waterproofing material is characterized by excellent adhesion to brick, their interaction gives excellent results. But at the same time, the masonry must be clean and dry. When processing wet bricks, the rubber will block the steam outlet, which will result in constant freezing of the building material. There is no point in waterproofing a brick foundation from the inside with liquid rubber, so cr 65 or cl 51 is better applied to external surfaces. In addition, only manual application material is used for finishing bricks.
3. Roof. Rubber will be relevant for industrial buildings that have a roof. Liquid rubber is not used in private construction, because it is expensive, and the appearance leaves much to be desired. If the roof is flat, then it is recommended to use additional waterproofing material that will work in tandem with liquid rubber. This will ensure high degree protection from mechanical damage.
4. Outdoor swimming pools. An excellent way to experience all the benefits that the cl 51 rubber waterproofing we are considering today, for example, has. It is not recommended to work with it in open areas if there is a risk of rain.

Liquid waterproofing rubber has not yet been appreciated, although the material is gradually gaining more and more popularity, as evidenced by reviews. If manufacturers are able to refine the appearance of the resulting layer and also reduce the cost, the composition will become firmly established in private construction. For now, this is the prerogative of industrial enterprises and buildings.

Liquid rubber for waterproofing is now widespread in many areas of construction. It is a new generation material created on the basis of bitumen. Liquid rubber is elastic, resilient and durable. It peels off poorly from the areas it is applied to.

Liquid rubber membrane coating is used on a variety of surfaces, such as concrete, steel, roofing felt and many others. This material is also called polymer-bitumen mastic. In some cases, the pond is even waterproofed with liquid rubber.

The main differences between liquid rubber and other waterproofing materials

Traditional bitumen mastic is close in composition to liquid rubber, but its scope is limited due to the characteristics of the components that are destroyed under the influence of ultraviolet radiation. That is, it cannot be used on open surfaces.

Advantages of liquid rubber

Disadvantages of the material

Methods of applying liquid rubber

1. Two-component rubber is sprayed airless. To perform this operation, special settings are required.
2. Single-component formulations are sprayed from units operating under high pressure.
3. Special one-component rubber can be applied manually.

For the convenience of consumers, some manufacturers have developed universal formulations that can be distributed over the surface in various ways.

Application area of ​​liquid rubber

Features of the application of the material allow it to be used for waterproofing foundations, swimming pools, ponds, roofs and floors.

Using liquid rubber, specialists carry out repairs and partial renewal of elements various designs. During road construction, the surfaces of manholes can be treated with emulsion.

In parking lots and large garages, liquid rubber is excellent. It is also used in shipbuilding to create a protective layer on sea and river vessels.

Reviews from builders about the use of liquid rubber for waterproofing objects buried in water

Manufacturers of sprayed mastics no longer need to prove to builders the importance of waterproofing objects. Companies that can accurately track all income, expenses, labor costs and time are now switching to liquid rubber. They explain this by saying that the material meets all their requirements. It is especially convenient to work with it when insulating pile foundations.

It is important for large developers to process a large surface area in the shortest possible time. With proper use of the equipment, a specialist can cover 600-1000 m 2 with waterproofing in 8 hours.

The required coating consistency is achieved by using a two-contact mixing device. After applying the composition to the surface, the formation of a primary monolithic layer takes about 10 seconds, this occurs due to the natural evaporation of water.

All of the specified parameters of liquid rubber make it popular among builders involved in the construction of buildings on difficult and wet soils.

Reviews from residents of brick houses about waterproofing masonry with liquid rubber

Manufacturers claim that the material they produce has excellent adhesion to different surfaces, brick is no exception. But builders warn about the special features when working with this type of foundation.

When using liquid rubber for waterproofing basements of buildings, you need to keep in mind that the masonry must be dry and free of contaminants. If the wall is wet, the insulation applied to it will block the steam escape, and the brick will always freeze very hard. Condensation can often be seen at the corners of such a basement. When using double-sided waterproofing, wet brick may begin to deteriorate after several cycles of freezing and thawing. This will also reduce adhesion.

Therefore, it is important to apply a layer of coating on the outside of the building, which is explained by the moisture absorption characteristics of the brick. Waterproofing the foundation with liquid rubber from the inside makes little sense, since the wall will be constantly wet. This measure will only protect the basement itself from dampness. In this case, the adhesion of the composition will only last for a few winters.

For brickwork It is better to use material that is applied manually. With proper distribution of the waterproofing layer, it will last more than 10 years.

Reviews from builders about the design and operation of roofs with liquid rubber waterproofing

In all areas of construction, waterproofing is a pressing issue. Liquid rubber, reviews of which are mostly positive, is one of the popular materials used for such purposes.

In private construction this composition is rarely used. What explains his unattractive appearance and high cost. Liquid rubber for waterproofing is used mainly in industrial facilities, for example, in garages, workshops, wastewater treatment plants and other facilities. When working with the material, the specialist must have personal protective equipment and insurance.

Some builders do not recommend using liquid rubber as the sole covering for a flat roof. Another compound must be applied on top of the waterproofing to protect its integrity during mechanical stress, such as heavy hail or routine snow removal. The edge of a shovel can instantly move part of a layer and leave behind an empty space.

Manufacturers claim that liquid rubber for waterproofing can last more than 10 years. This only applies to situations where it is top coated with solvent-free paint. Otherwise, its service life is approximately 5 years.

Waterproofing of buildings is of fundamental importance, because the service life of building structures depends on its quality. High demands are placed on materials for moisture protection. They must be not only hydrophobic, but also resistant to wear, ultraviolet rays, and temperature changes. The ideal waterproofing material is seamless, because... joints and seams are always the “weak link” of moisture protection. Such material exists. Below in the photo is liquid rubber, an elastic seamless coating for reliable waterproofing of the roof, foundation, and walls.

This is a sprayed bitumen-based material that is suitable for creating moisture- and heat-resistant seamless coatings. It is used for flat building structures. Thanks to the reasonable cost of the material itself and simple application technology, we obtain budget waterproofing, which is not inferior in quality to more expensive analogues.

Photo of a roof made of liquid rubber

The name is associated not with the composition of the material, but with its properties and technical characteristics. This is a cold-applied polymer-bitumen waterproofing material. After drying, the result is a coating that stretches well and is highly hydrophobic. This type of mastic is called liquid rubber for the convenience of customers.

To apply liquid rubber, airless spraying technology is used. The material fills all the pores and microcracks of the base, quickly gains strength and creates a monolithic membrane-type coating. But while conventional membrane waterproofing is not characterized by resistance to mechanical damage, liquid rubber is more stable due to its high elasticity.

The waterproofing composition includes environmentally friendly components. Under constant loads, it can last for several decades. This is possible due to its self-healing ability: small punctures are healed, which is not typical for other types of coatings.

Demonstration of the strength and elasticity of the material

Technical and operational properties

• Fast curing. The material gains 80% strength almost immediately after application and hardens quickly. Thanks to this, work time is reduced. There are no joints or seams left.
• Light weight. Thin and light coating does not create additional load on building structures.
• Good adhesion. Mastics can be used on almost any surface. For fastening, no special devices are needed - nails, staples or dowels, so the base remains without damage.
• Durability. A high-quality coating can last at least 15-20 years, because... retains properties under the influence of external negative factors.
• Versatility. Polymer-bitumen mastics can be used for waterproofing structures of any configuration - with protrusions, corners (up to 20 degrees), vertical surfaces.
• Wide temperature range. The material can withstand temperatures from -45°C to +98 degrees Celsius. Some compositions are adapted for regions with harsh climates and retain their properties at temperatures of -60 degrees.
• Environmental friendliness. The basis of the mastic is a polymer-bitumen water emulsion. After hardening, the material does not evaporate and does not emit when heated. toxic substances into the atmosphere, does not harm human health.
• Minimum consumption. In practice, it has been proven that a 2 mm layer of liquid rubber is not inferior in its technical properties to a 4-layer rolled roofing. For reliable waterproofing, spraying with a thickness of 3-4 mm is used, depending on the type of base.
• Maintainability. If the coating is damaged, it is easy to repair.
• Color variety. Most often you can find black mastics on sale, but there are materials in other colors. The bitumen-polymer composition is compatible with water-based dyes, and if desired, the buyer will be able to find mastic of the desired shade.

Applying mastic using a spray gun

Types of liquid rubber

The material is classified not by composition, but by the method of application to the surface. Depending on this, there are three main types of waterproofing:

Bulk

The mastic is poured onto a flat surface and carefully leveled with hand rollers. The application technology involves preparing the base: it is primed using bitumen emulsion. A layer of basic waterproofing is applied to the prepared surface, allowed to dry for several minutes, and then poured finishing coat. Most often this method is used for flat roofs and floors.

Manual application of liquid rubber

Sprayable

For application, special sprayers with a working pressure of 15 bar are used. This perfect option, if you need to treat a large area or vertical surface. The material fills all microcracks, prevents dust formation and protects structures. The coating is of high quality, and the work itself can be completed in a short time.

Painting room

This application method is suitable for processing small objects and is convenient because it does not require the purchase of special equipment. A spatula, short-haired roller or stiff brush is sufficient for the job. The material is applied in two layers: the first is the primer, the second is the main layer (thickness of at least 3 mm). It takes two days for the insulation to dry completely and gain maximum strength.

Areas of application of the material

Waterproofing mastics are widely used in private construction. The material is well suited for protecting roof structures, foundations, floors, and walls. It is used for the construction of artificial reservoirs, swimming pools, and large water tanks at public utility facilities.

Mastic is applied to obtain a waterproof coating on pipelines, it strengthens dams and dams, and protects roads, tunnels, and mines. Since liquid rubber also has soundproofing and anti-corrosion properties, its scope of application is practically unlimited. It is suitable for waterproofing many civil, industrial, and military facilities.

Pool waterproofing

Liquid rubber can be used as a stand-alone waterproofing solution or in combination with other coatings. It adheres perfectly to structures made from the most different materials:

• reinforced concrete;
• rolled roofing materials;
• cement screed;
• wood;
• metal;
• slate;
• various types tiles.

When choosing waterproofing materials Please note that the liquid rubber coating can only be removed mechanically. It is sensitive to substances that contain petroleum products. For some types of structures, such as pitched roofs, liquid rubber is not suitable; it is better to use other materials.

Old roof after repair

How to make waterproofing yourself

Liquid rubber can be used both in the construction of new buildings and in the reconstruction of old ones. Not required for application complete removal worn coating, but it is necessary to remove accumulated moisture from it. For this purpose, special deflectors are used, and sometimes the surfaces are additionally reinforced with geotextile materials.

Rules for calculating the amount of material

To correctly calculate the required amount of mastic, rely on the information provided by the manufacturer. If the exact consumption is not indicated, we can assume that covering 1 m2 with a layer 1 mm thick will require about 1.5 liters of material. Therefore, it will be necessary to take into account the area and optimal thickness of the membrane.

To seal seams and joints, provide anti-corrosion protection, and cover wood, a layer of 1.5 mm is required. If roof waterproofing or protection of concrete or reinforced concrete structures is needed, then the minimum membrane thickness should be 2 mm, and the optimal thickness should be 3 mm.

DIY house roof repair

Work order

1. The base must be thoroughly cleaned, if possible washed using special equipment and dried, and burn off greasy stains from the old roofing material.
2. The mastic is prepared for use in accordance with the manufacturer's instructions.
3. Regardless of the chosen application method (manual or mechanized), the composition is distributed over the surface in strips 1-1.5 m wide, leaving no untreated areas.
4. The seams and joints of the base are reinforced with geotextile materials.
5. If priming is carried out using two components - an activator and a bitumen-polymer emulsion, then it is performed mechanically. An indicator of the quality of processing is the rich black color of the finished membrane.
