Sprayed waterproofing - technology of application and variety of materials. Liquid rubber waterproofing Liquid rubber: new generation waterproofing

Waterproofing is the most important stage in the construction of the roof. Not only the microclimate in the premises of the building, but also its reliability largely depends on how and with what it will be performed. Waterproofing is recommended for any roofing. It is she who is responsible for the timely removal of accumulated steam and condensate from the attic space, thus preventing the destruction of the materials used to build the roof. There are several methods for waterproofing. Sprayed waterproofing is especially popular. About its features, advantages, disadvantages and installation rules - in more detail.

Spray waterproofing is one of the few ways to create a water-repellent layer of a roofing pie, performed by applying a special material - a two-component system based on a bitumen emulsion with the addition of polymers (liquid rubber). She is:

  • contributes to the formation on the treated surface of a monolithic membrane without seams and joints two millimeters thick, which reliably protects the roofing and heat-insulating material from excessive moisture, steam and condensate;
  • differs in reliability, endurance, resistance to influences of natural character;
  • can be used even in extreme conditions, as it is resistant to sharp temperature fluctuations and UV radiation.

It is important to know: the waterproofing layer, arranged by the method in question, is able to flawlessly perform its main functions in the temperature range from -47 ° C to +98 ° C.

Unlike other, more traditional methods, spray waterproofing does not involve mechanical joints and seams, it is this important feature that guarantees the absence of subsequent roof leaks. The liquid bitumen-emulsion system, after application, adheres tightly and reliably adheres to the insulated surface, forming an inseparable water-repellent layer. If waterproofing from membrane films and other rolled material during operation quickly deforms and becomes unusable under the influence of natural factors, then the option under consideration can last up to 25-30 years without annual repairs, without leaking.

Waterproofing by spraying allows you to create a complete membrane coating without joints and seams

The main advantages of the considered method of waterproofing

Seamless sprayable waterproofing, which involves the formation of a high-quality water-repellent anti-corrosion membrane coating, is endowed with a number of unique physical features. These include:

  • UV resistant. The coating does not deform and does not change its technical features under the influence of sunlight, which is not typical of every waterproofing material.
  • Eco-friendly and non-toxic composition. Liquid rubber consists of non-toxic polymers and bitumen emulsion, therefore, during operation, it does not emit hazardous substances that can harm a person or the environment.
  • Excellent adhesion to concrete, wood and many surfaces. After application, the bituminous emulsion system hardens instantly. It adheres reliably and tightly to any treated surface, forming a dense, waterproof layer.
  • No seams or joints. Most often, the roof leaks in those places where the joints of the waterproofing material are located. Waterproofing by spraying avoids these unpleasant incidents.
  • Ease and speed of application. Waterproofing by the considered method, if desired, can be performed even by an unprepared person. Liquid rubber is applied and hardens very quickly, if desired, up to 1000 square meters of waterproofing layer can be applied per shift.
  • Fire resistance. Liquid rubber does not ignite and does not spread fire well.

It is important to know: the service life of waterproofing, arranged by spraying, can be 25 - 30 years only if all the preparatory and installation work is done correctly.

The physical properties of the waterproofing layer applied by spraying allow it to be as reliable, durable, durable and elastic as possible.

Scope of application of seamless sprayed waterproofing

Sprayed waterproofing has found its application not only in the production of waterproofing roofing, in the construction of new, inverted and conventional roofs, their repair on the old coating, but also in many other areas: in ship engineering, automotive industry. It is resorted to when there is a need for waterproofing basements and basements, it is used as an effective anti-corrosion agent for protecting structures, both metal and concrete.

It is important to know: sprayed waterproofing, due to its properties, is able to serve for a long time, despite the conditions in which it is used. The high tensile strength characteristic of the waterproofing layer applied by spraying prevents the possibility of its cathodic delamination from the surface due to temperature effects, sharp shocks, pressure of accumulated water, vibration. Hardening, it does not become brittle and brittle, retains its impeccable elasticity, does not deform, does not give in to peeling and does not crumble.

Sprayed waterproofing has found its application in many areas of our life. For example, when waterproofing pools

Rules for spraying a waterproofing layer

Seamless sprayed waterproofing is applied to a previously cleaned, dry, degreased surface with an antiseptic using a special dual-slope device that sprays liquid rubber in an airless way, at a temperature not lower than +5 °C. It is also possible to apply the composition on a damp surface.

Sharp internal and external corners, junctions and necessary resistance to traction with separation before waterproofing are reinforced with a special non-woven thermally bonded textile with a density of up to 200 grams per square meter. The waterproofing material hardens after mixing all its components in a torch, instantly on the treated surface.

If you strictly follow the rules for spraying waterproofing, it will last a long time, properly performing its main functions.

It is important to remember that only a professional with experience who is fluent in technology and knows all the subtleties of the process can correctly and with the highest quality apply a liquid bitumen-emulsion system to a roof surface or other base. In view of this, it is highly undesirable to carry out the work on your own, otherwise the seamless sprayed waterproofing will not be able to justify itself.

Sprayed waterproofing is used to protect roofs, foundations, basements, underground rooms from moisture. Sprayed waterproofing has a number of advantages - a high level of fire resistance, long service life, no smell, no seams, good adhesion to any substrate, regardless of the surface topography.

Many people think that sprayed is one and the same, but this is absolutely not the case. This type of waterproofing consists of two components - a basic base and a rejecting catalyst. The process of coating the sprayed waterproofing occurs by cold spraying of the solution, which, after hardening, forms a strong shell.

Polyurea has become the main material used for sprayed waterproofing. This is an ultra-modern waterproofing coating, which, due to a number of advantages, has made sprayed waterproofing the most promising type of waterproofing.

Video: Foundation waterproofing with liquid rubber

Polyurea was first created by American scientists in 1989. Since then, a very dynamic promotion of this waterproofing material has begun in the markets of the USA, Canada, and Europe. In domestic open spaces, polyurea appeared not so long ago, but has already gained great popularity, and all thanks to its unique hydro-repellent properties.

There are several most distinctive positive points that relate to polyurea:

  • Fast and easy to use. With sprayed waterproofing, more than 500 square meters can be covered. m in one working day.
  • Sprayed waterproofing is used on any terrain, without requiring any preparation for this. When applied, it will simply repeat the shape of the surface to be coated.
  • The level of protection against moisture is as high as possible, even if a layer of only 1 mm is applied.
  • Sprayed waterproofing is applied seamlessly and retains high elasticity under the influence of different temperatures. A big advantage was its resistance to cracking.
  • High level of abrasion resistance and durability of the materials used.
  • Good connectivity with all kinds of building materials.
  • Warranty over 30 years.
  • A huge positive point was that polyurea and other components of sprayed waterproofing are environmentally friendly materials.

The creation of polyurea took place taking into account its molecular structure, which allows it not to settle during use and maintain its shape for a long time.

Video how to perform waterproofing work

Now we offer to watch a few videos, where waterproofing work is carried out using the technology of cold laying of a seamless liquid rubber coating.

Waterproofing works in Vladivostok. The video was provided by a dealer in Primorsky Krai.

Waterproofing works in the Krasnoyarsk Territory, the Irkutsk Region and Yakutia will be carried out by the construction division of a dealer from the Krasnoyarsk Territory.

Roof waterproofing works in Novosibirsk. The laying of the coating is carried out by the construction division of the dealer in the Novosibirsk region.

To perform waterproofing work in the Ivanovo, Vladimir and Kostroma regions, a partner of Technoprok from the city of Kineshma is taken.

If you want to perform waterproofing work in the Chernozem region, we recommend contacting our partner Technoproc from Orel. The video shows the installation of a roof covering in Kursk.

We offer materials based on bituminous, polyurethane, acrylic and epoxy bases. Offices and warehouses of our partners and dealers are located in several dozen Russian cities.

This is an advanced oversized installation for airless two-component spraying of Technoproc or Rapidflex bitumen-polymer emulsion. Click on photo to enlarge.

The small dimensions of the MB-24 modification are the main difference from the B-21 model, which has been produced since 2010. Dimensions and weight - these are the 2 parameters that not always and not everyone liked about the flagship Technoprok B21 installation.

To install the B-21, the gasoline engine and belt drive require a reinforced and voluminous frame. Powerful pumps and gearbox require a heavy frame. As a result, the mass is more than 100 kg, and the dimensions are approximately 1 m3.

However, any professional understands that gasoline equipment is more convenient and functional. Why?

  • Autonomy on site. There is no need to coordinate with someone the points of connection to the power grid, there is no need to carry a generator with you. 4 liters of AI95 gasoline provide 4 hours of uninterrupted battery life. During this time, you can make up to 500 m2 sprayed roof.
  • Long range without sacrificing performance. For the B-21, this is 80m on the horizon.
  • Height of supply of components without pressure drop in the lines. For B-21 this is 40m, i.e. the installation, and most importantly, the barrels with the material, remain on the ground when it is necessary to repair the soft roof of the twelve-story building.
  • System for regulating the pressure of components in the lines. This assembly allows you to adjust the optimal pressure and achieve high-quality spraying of liquids.
  • Recirculation system that allows the operator to turn off the taps on the rod at any time, even when the engine is running. In this case, the components are pumped along a small circuit and fed back into the drums.
  • Rigidly specified ratio of components. This means that there is no need to recalculate the mixing ratio when extending the hoses or when feeding upwards. The pumps work synchronously, because mounted on a common shaft.
  • Long stops are allowed, because a powerful engine will “turn” the pump through liquid rubber, even when the emulsion has begun to break up.
  • In addition to applying waterproofing liquid rubber, it is used as a manual road asphalt distributor.
  • and many other "little things" that make working on a gasoline unit easier, more convenient, faster and clearer.

And yet, there were cases when, for someone, all the advantages of the B-21 gasoline unit were outweighed by its mass and volume. And then the buyer chose a compact electrical installation for 220V.

And then the Technoprok employees had to listen to something like this: “Why is the installation with a gasoline engine so big? Do everything the same, but to make it smaller and lighter, so that you don’t carry it with a Gazelle, but fit in the trunk of a passenger car.

In May 2015, Technoprok developed such an installation. Small and not heavy, like the electric E-22, but with a gasoline engine, like the B-21. According to Technoproc classification, the new unit received the MB-24 index.

Polyurea spray waterproofing is the formation of a monolithic thick-walled film coating on the surface, which is characterized by high strength and elasticity. The protective shell is formed as a result of the reaction of two components - isocyanate and resin. In our article, we will consider the subtleties of handling these components and the technology of spraying the composition onto the base in order to protect it from moisture.

Features of the use of polyurea for waterproofing

The polyurea coating is formed by the reaction of two components that are applied to the surface under high pressure. After application, the substance quickly hardens, forming a seamless web.

Two types of polyurea are used for waterproofing - pure and hybrid. The first option is used in harsh operating conditions, for example, at low temperatures, but its price is very high. In most cases, a hybrid option is used.

Manufacturers introduce additives into the substance, due to which the product, in addition to waterproofing, acquires other properties. A wide range of products allows you to choose a tool for each specific case. For example:

  • A reflective coating is mounted on the roof, which saves on insulation.
  • The compositions intended for floors and foundations are elastic, well resist mechanical loads.
  • For floors, you can choose polyurea, which allows you to get smooth and rough surfaces.
  • The product has proven itself well for waterproofing steel pipes.
  • Applying polyurea to the facade not only increases its moisture resistance, but also increases its service life.
  • You can purchase samples of any color and finish the interior surfaces of pools or aquariums.
Additives slightly worsen the properties of the material, but hybrid compounds cost less than pure polyurea. The technology for applying an insulator depends on its components, so check the requirements of the substance manufacturer in advance.

A feature of the insulator is a high curing rate, which eliminates the influence of various negative factors on the quality of the coating. In this way, the surface can be processed at low temperatures. The substance is capable of waterproofing the substrate in conditions where other protection options do not work.

It is necessary to work with the product in special suits that cover the skin, eyes and respiratory organs.

Advantages and disadvantages of polyurea waterproofing


The coating of this material has many positive qualities that distinguish it from other water repellents.

Advantages of polyurea:

  • Polyurea does not require repair and replacement for 50 years. After long-term use, it does not deform from mechanical, thermal and chemical influences, does not lose its performance characteristics, does not shrink or crack. Wear resistance exceeds even the norms for ceramic tiles. If necessary, the surface of the film is easy to restore.
  • Using sputtering technology, a seamless waterproof shell of high reliability is created.
  • The product is safe for humans, because. it contains no toxic components.
  • The process of forming a coating based on polyurea is very simple. During operation, there is no need to adjust the materials, fix them, seal the joints.
  • Spraying is carried out using special devices that allow you to process an area of ​​300-400 m 2 in a short time.
  • The urea-based sheath does not burn and can be used in fire hazardous areas.
  • The curing speed of the substance is very high - no more than 20 seconds. It is possible to start operation an hour after application, but the coating acquires maximum strength later.
  • Polyurea seals surfaces of any shape. It has good adhesion to almost all materials used in construction.
Even such a modern waterproofing agent has disadvantages that limit its use:
  1. Some varieties of polyurea are not sufficiently resistant to ultraviolet radiation, so carefully study the composition and properties of the components before buying.
  2. Raw materials for spraying a substance are expensive.
  3. For work, you will need expensive equipment, without which it is impossible to apply the substance. Work on professional devices can only be specialists who have undergone special training.
  4. The tool will reliably protect any surface from water, but it is not able to hide its flaws.

Surface waterproofing technology with polyurea

Waterproofing is carried out in several stages. First, it is necessary to carefully prepare the base for processing, determine the type of equipment for polyurea, and only then proceed to the spraying process. Information about each step is provided below.

Selection of Polyurea Spray Equipment


The insulator is applied to the walls by spraying with the help of special devices, which are selected depending on the area of ​​the treated surface, the desired quality of the coating, the operating conditions of the containment and other factors. To obtain a working composition, the components are mixed at a temperature of 60-80 degrees in a ratio of 1: 1, under a pressure of 150-200 atmospheres. Therefore, the composition of the device necessarily includes such components as containers with chemicals, pumps, a dispenser, a mixture heater, special hoses for supplying a substance that maintains a given temperature, and a sprayer.

Universal fixtures designed for light and medium loads are not suitable for applying polyurea. They are not designed for high pressure in the system. Each modification of the substance requires a certain type of gun, its own mixing chamber size, pressure, temperature. All recommendations for the selection of equipment are given in the instructions for the composition developed by the manufacturer of the substance.

With a small amount of work, mobile one-time installations are used, usually pneumatic. With their help, small areas are processed - balconies, basements. The simplest installation includes two cylinders of polyol and isocyanate, a long flexible twin hose, a gun with nozzles. Devices do not always have a device for adjusting the proportion of components; there is no function for heating the contents. In such systems, the acceptable temperature is maintained using barrels of warm water. With some skills, disposable devices can qualitatively process even complex-shaped surfaces.

Electrical devices have an average performance and are designed to process large areas.

Hydraulic devices belong to the class of professional devices. They provide excellent quality waterproofing, are designed for a long service life, and have increased reliability. Dosing of reagents is carried out using piston pumps.

For spraying polyurea, it is necessary to use a spray gun with a flat jet, while for pneumatic and hydraulic devices sprayers of different designs.

Preparatory work


Before spraying, the surface should be carefully treated. To do this, perform the following operations:
  • Remove dirt in various ways - with a strong water jet, a stiff brush, a grinder, etc.
  • Check the flatness of the base. Irregularities do not affect the quality of the waterproofing, but after the work is completed, the shell will look unaesthetic. Make sure that there are no oil stains and paint on the wall, the composition does not adhere well to them.
  • To improve adhesion, the surface to be treated must be rough. If necessary, go over it with a stiff brush.
  • Prime cement screeds to reduce the consumption of polyurea and increase the strength of the base.
  • Additional processing will prevent peeling of the plaster. If porous materials are not primed, then craters and other defects form on the surface. It will not be possible to disguise them even by repeated spraying.
  • Check concrete walls for weak areas. If found, cut them down, and fill the resulting voids with repair compounds. Fill the holes from the fasteners with expanding compounds to a depth of 4-6 cm.
  • Round sharp corners, knock down the influx of concrete. Putty shells with a diameter of more than 10 mm. At the junction of horizontal and vertical sections, fillets are made.
  • If polyurea, in addition to waterproofing, is planned to be used for decoration, the requirements for the surface are increased. It is necessary to ensure the horizontality or verticality of the treated walls with a tolerance of 1 mm per 1 m. The number of nicks with a diameter of 1-2 mm per 1 m 2 should not exceed two.
  • Brick partitions must be plastered with a cement-sand mixture. Polyurea can be applied after a month, so that the lining acquires maximum strength.
  • After leveling the surface, it must be primed with a special composition designed to work with polyurea. It is advisable to use those compositions that are recommended by the manufacturer of the waterproofing agent.
  • On metal products, sand the welds and sandblast everything else. Rinse and dry the surface after the procedure. Metal surfaces are not primed, only coated with an anti-corrosion compound.
Polyurea may be sprayed if the following requirements are met:
  1. The surface moisture level does not exceed 4%. The value is determined by a special device - a moisture meter. In its absence, you can use the folk method. Lay a large piece of plastic wrap over the base and tape it on. Check her condition after three days. If wet spots appear, the wall should still dry out. It should be remembered that a polyurea coating is formed even if the material is sprayed onto ice, however, the shell will not adhere to the surface.
  2. Permissible air humidity - less than 80%.
  3. The ambient temperature must comply with the conditions specified by the raw material manufacturer.

Instructions for applying polyurea


Surface waterproofing is carried out after the primer has completely dried. The assembly of the product is very simple and takes only a few minutes.

Working with disposable installations does not require special skills, but before that it does not hurt to simulate spraying with the gun turned off. Practice intercepting the gun and moving around with it. You can’t release the trigger, the composition will instantly harden in the nozzle, and it will have to be changed. Professional units are complex and require special training on how to operate the unit before use.

The classic polyurea spraying process is as follows:

  • Assemble the device according to the manufacturer's instructions.
  • Connect the hardener and resin cans to the heater with hoses.
  • Turn on the pump to supply formulations to and from the heater. The process stops when the entire volume of reagents is not heated to a temperature of 60-80 degrees.
  • After liquefaction of the components, the device redirects the materials for spraying. The same pumps pump the substance to the nozzles through special heated hoses. Each component emerges from individual holes in the gun and mixes as it is applied. The polymerization process immediately begins, and after a short period of time the substance solidifies, forming a film coating.
  • In some systems, mixing takes place in a special chamber built into the gun. To obtain a high-quality mixture, the pressure in it, as well as at the exit from the nozzle, must be sufficiently high.
  • Spraying is carried out in strips 1.5-2 m wide with an overlap of 15-20 cm on adjacent areas. Treat surfaces twice: first in one direction, and then perpendicular to the first layer. The thickness of the applied layer is 1-3 mm, the standard value is 2 mm. After 10-12 hours, the strength of the polyurea will reach a maximum.
  • In some cases, the coating is applied with two compositions, for example, when waterproofing pools. The top ball with the addition of dye replaces the decorative layer.
Useful tips when working with polyurea:
  1. Keep the heated hose away from moisture to avoid electric shock.
  2. Do not allow water to enter the hardener. If this happens, the substance will instantly foam and harden. Therefore, the apparatus for spraying must have a filter that traps moisture.
  3. When waterproofing critical places, fiberglass must be built into the protective shell. It will protect surfaces from high mechanical and thermal loads.
  4. After work, wash the sprayer from the solution.
  5. It takes 3 people to work. One directly sprays, the second helps move heavy hoses, the third controls the operation of the device.
How to apply polyurea - look at the video:

Waterproofing coatings of all types must adhere securely to the base, be continuous, of uniform thickness.

Purpose of waterproofing

Waterproofing- a dense waterproof layer of paint, roll or other materials designed to protect building structures from moisture from groundwater or other liquids. In buildings and structures, waterproofing ensures their durability and normal operation. Consider where the waterproofing is located in various buildings and structures. In a residential building, the outer surfaces of basement walls, foundations and other underground structures in contact with the ground are insulated. In the floors of sanitary facilities, waterproofing prevents wetting or leakage of interfloor ceilings.Floors and walls in baths, laundries and other wet» rooms are protected from the inside with a layer of waterproofing to prevent moisture and reduce the heat-shielding qualities of building envelopes. In attic floors, if necessary, arrange a vapor barrier- type of waterproofing.Vapor barrier prevents the penetration of water vapor from the room into the insulation. Without vapor barrier, water vapor would penetrate into the insulation, and when cooled, it would turn into condensate, which would cause the insulation to become moist and its thermal insulation qualities would decrease.

The main types of waterproofing

Depending on the position in space, waterproofing is divided into horizontal, laid on a horizontal surface, and vertical - on a vertical or inclined surface.According to the method of construction and the type of materials used, the following types of insulation are distinguished:

- multi-layer coating of plastic or liquid compositions.

Rice. 1. Paint waterproofing: 1 - foundation; 2 - waterproofing; 3 - overlap; 4 - floor.

Such waterproofing is performed from hot or cold bituminous mastics, as well as from compounds prepared on the basis of synthetic resins. The composition is applied in a uniform layer over the entire insulated surface with small amounts of work with brushes or rollers, with an insulated surface area of ​​​​more than 500 square meters by mechanized method.

Bituminous insulation is made in at least 2 layers, each 2 mm thick, insulation based on synthetic resins - with a layer of 0.5 ... 1.0 mm. Depending on the type of mastics used, the layers are applied at intervals of 1 to 16 hours after the previous layer has hardened and dried.In attic ceilings and coatings of industrial buildings, paint waterproofing, which acts as a vapor barrier, is applied in 1 layer.

- a coating of several layers of rolled, film or sheet materials, which are glued in layers with hot or cold bituminous mastics or synthetic compounds.

Rice. 2. Pasting waterproofing: 1 - foundation; 2, 6 - waterproofing; 3 - protective wall; 4 - clay layer; 5 - groundwater level; 7 - fold of pasting carpet.

Isolation is done like this. The panels are rolled out in one direction and connected to one another with an overlap of 100 mm in the longitudinal and transverse seams. In adjacent layers, the longitudinal and transverse joints of the panels are spaced not closer than 300 mm from one another. The number of layers is determined by the project. A continuous layer of hot bituminous mastic is applied to the last layer of rolled insulation and protected with a wall of brick or other materials.The vapor barrier of horizontal surfaces from rolled materials is made single-layer. At the junction with the walls, it is brought to a vertical surface so that the thermal insulation from the side of the wall does not get wet.

- a coating with a thickness of 5 ... 40 mm, which is applied in layers from cement-sand mortars (composition 1:1 or 1:2 ) using waterproof cements. On a small area (up to 100 square meters) and in the absence of hydrostatic pressure, the coating is applied manually, in 2 ... 3 strokes on a pre-moistened surface. The thickness of such insulation is not more than 30 mm.

Rice. 3. Cement plaster waterproofing: 1 - reinforced concrete wall; 2, 3 - layers of cement-sand mortar.

- a covering up to 20 mm thick from hot or cold mastics. Cold mastics are applied in layers (basting thickness 2...4 mm).

Mastic is poured or sprayed onto horizontal and inclined surfaces, followed by leveling, usually in 2 layers of 7-8 mm.

Rice. 4. Stucco Asphalt Waterproofing: 1 - reinforced concrete wall; 2, 3 - layers of asphalt mastic.The vertical surface of the waterproofing is protected with a wall of bricks, concrete slabs or a layer of cement plaster, reinforcing it with a steel mesh; horizontal - with a cement mortar or concrete screed.Hot mastic is applied in 2 ... 3 layers on the surface from the side of moisture or hydrostatic head. Protected from the outside.

Cast asphalt waterproofing - a coating of hot mortar or mastic in the cavity between the surface to be insulated and the protective wall. This is how the isolation works. The asphalt mixture is poured onto a horizontal surface and level it with scrapers, lay a cement or mortar screed on top.

Rice. 5. Cast asphalt waterproofing: 1 - reinforced concrete wall; 2 - a layer of hot asphalt or mastic; 3 - a protective wall made of bricks.Spray waterproofing

Materials used for waterproofing: polyurea, Hyperdesmo polyurethane mastic, Unicoat-101 and other elastomeric coatings, which are applied by spraying with imported high-performance high-pressure equipment.
