Liquid insulation for roofing. Original roofing and designer roofs: How to cover a roof with liquid roofing - instructions for waterproofing and photos. Types and types of liquid roofing and tiles - self-leveling polymer roofing, sprayed seamless liquid rubber, mastic

• The main purpose of roofing coatings is to protect the house from precipitation and other negative influences. Therefore, the construction industry is in constant search advanced technologies, innovative materials that can better cope with the task. IN last years Quite a few new roofing materials have appeared on the scene. Among them are their own unique qualities liquid roofing, or as it is also called, compares favorably liquid rubber for the roof. The coating made from this material is solid, without a single seam, and absolutely waterproof on almost any base, regardless of its shape and slope.

  Imagine how beneficial it is to use liquid rubber for large areas or structures with complex terrain such as junctions, etc. Moreover, unlike roll and analogues, in this case we are dealing with a more convenient and waste-free method of coating. So what is liquid roofing?

  Liquid rubber and waterproofing of roof elements

  This coating and waterproofing material consists of two main components: an emulsion of bitumen and latex. After application to roofing elements liquid rubber mastic, one might say, immediately hardens and takes the form of an elastic, seamless membrane. As already noted, neither the roof configuration nor its dimensions play any important role.

  

  Rubber liquid coating classified based on application technology:

  • liquid In this case, the mastic is poured and leveled manually;
  • sprayed. When applying, special equipment is used. The use of specialized equipment significantly increases the speed of work performed. At the same time, mastic consumption is also reduced;
  • painting The material is distributed manually using spatulas, brushes or rollers.

  On a note

  In principle, this roofing material is practically not similar to the rubber itself, which is made from rubber. That's actually why rubber waterproofing not much like liquid rubber. And the very name of the material is just a matter of habit.

  

  The material is produced in two versions: one-component liquid rubber for roofing and two-component:

  • one-component is a mixture that is initially ready for use; it does not need to be mixed or any other additional operations are performed. The main purpose of the material is sealing;
  • two-component consists of a base element and a curing catalyst, used to produce a mastic membrane. The most common composition includes:

1. bitumen-polymer emulsion on water based; polymer-modified liquid bitumen;
2. solution of technical calcium chloride.

During application of the composition, the saline solution enters the emulsion, and in a split second, two processes begin simultaneously:

• emulsion breakdown
• polymerization of latex.

As a result, bitumen immediately turns into a very viscous substance and forms a rubber-like film within a few minutes.

On a note

The liquid roofing membrane is sprayed in one layer in one pass. This ensures required thickness layer.

Specifications

One of the main qualities of such a coating is its exceptional adhesive characteristics.

• It adheres equally well to concrete and rolled materials, wood, tiles, and metal;
• Resistant to large temperature fluctuations and exposure to ultraviolet radiation and ozone rain;
• Has a high degree of resistance to aggressive influences external environment, does not corrode;
• Environmentally safe;
• The material is economical in consumption: 1–3 kg of composition is needed to process 1 m2;
• The covering has no seams and is completely waterproof.

Let us note a number of other valuable properties of liquid roofing:

• 100% steam, water and gas tightness;
• light weight (roll materials weigh about 4 times more);
• the coating is fireproof and non-toxic;
• its structure remains unchanged throughout its service life;
• the coating is vibration resistant;
• the amazing property of smart memory of the material, when random holes are tightened on their own;
• unsurpassed elasticity, which remains at the same level even over the years, although the roof may become harder.

It is also worth noting how easy it is to repair such a membrane: apply a layer of rubber to the damaged area in a “cold” state and that’s it. Let us remember for comparison how. Here you cannot do without heated tar used for gluing sheets, which requires maximum care.

However, according to reviews not without shortcomings. First of all, it's enough high price coatings compared to others. Although from the point of view of economic feasibility, this opinion is controversial, because the minimum guaranteed service life of such a roof is 20 years. Secondly, insufficient resistance to certain solvents and oil-containing products.

Application area

The scope of use of such compositions is very wide, since high adhesion allows such a coating to be applied to any substrate. Rubber waterproofing is performed on roofs:

• multi-storey residential and country houses;
• industrial and utility buildings;
• shopping complexes, etc.

Although its advantages are most pronounced on large surfaces, in recent years, liquid roofing for garages has also gained great popularity. Solid seamless waterproofing, including the junction points, provides maximum protection against leakage. Roof waterproofing with liquid rubber is carried out in two stages:

• first prime the surface,
• then the base coat is applied.

If you apply the composition to an old garage coating with minor defects, you can “save” it from further damage.

For the repair and restoration of soft roofs, Ureplen would be an excellent solution.

Waterproofing issues can be advantageously resolved with the help of a building material – liquid roofing. High specifications roof coverings provide reliable properties of waterproofness, strength, long service taking into account a wide temperature range from –45 °C to +98 °C.

The material is recommended for use in various climatic zones due to its resistance to extreme weather conditions. During the installation process, a seamless coating is ensured. Compared to rolled products, liquid rubber based on polyurethane is characterized by close contact with the surface, better sealing, and vapor permeability.

What is liquid roofing?

Liquid rubber for roofing is one of the modern universal building materials, made on the basis of a polymer binder. It is gradually replacing roofing felt, which, compared to new development less effective.

The roof is an important part of the structure of a structure, regardless of its functional purpose. Therefore, the materials used in its construction must meet high operating requirements: be resistant to precipitation and temperature changes.

Liquid rubber for roof – the best option, effectively protecting the roof from the destructive effects of snow and rain, from corrosion and sunlight. The main property of the coating is moisture resistance. The material is suitable for construction, repair and restoration of outdated roofs. Unique characteristics have provided liquid rubber with wide application.

Types of liquid rubber

This, depending on the composition, can be one-component or two-component.

In the first case, rubber is a paste-like homogeneous mass of a stable nature based on a bitumen-latex emulsion, characterized by high viscosity. Upon completion of application to the surface, the composition polymerizes and a perfectly smooth coating without seams with excellent waterproof properties is formed.

One-component liquid rubber is intended for:

• ceiling, vertical and horizontal surfaces;
• for roofs in administrative, residential buildings, and shopping malls.
• coatings with reliable adhesion of reinforced concrete, brick, metal, wood, concrete, stone.

Two-component waterproofing is made on the basis of a bitumen-polymer emulsion with a high content of water component. The composition is applied to the surface by spraying. Production technology helps improve the fireproof, environmental properties of the material, which does not contain harmful impurities that release toxins into the atmosphere.

To apply a two-component liquid roof, specialized equipment and tools are used. The rubber-like membrane takes on a continuous, seamless appearance.

Most frequent use composition:

• roof waterproofing;
• covering the ceiling structure in underground structures;
• insulation of parking lots and roofs of production workshops;
• industrial use.

Advantages and disadvantages of liquid roofing

Polymer-bitumen material for roofing waterproofing does not contain volatile components. After surface treatment, active evaporation of water occurs, due to which the mixture ideally polymerizes and sets.

The building material is often used not only outside, but also indoors due to its key advantages:

• receiving waterproofing coating with no seams, high elasticity, similar to rubber;
• formation of reliable adhesion to almost all types of bases;
• prompt application of the composition to the surface due to the appropriate consistency;
• processing of ceiling, vertical and horizontal surfaces;
• providing durable waterproofing coating in hard-to-reach places;
• explosion and fire safety;
• resistance to negative impact aggressive environments;
• possibility of long-term operation in a wide temperature range;
• resistance to sun rays and ultraviolet radiation;
• environmental safety, absence of harmful volatile compounds;
• compliance with GOST and European standards.

The disadvantages include the following:

• It is not recommended to apply liquid rubber coating during rain or snowfall;
• the use of the material in close interaction with liquids of organic origin, including solvents, petroleum products, oil, gasoline, should be limited;
• The bitumen-polymer composition cannot be frozen, as in this case it loses its beneficial properties.

Scope of application of liquid roofing

Liquid rubber is used in construction, during the reconstruction and repair of buildings, helps to ensure a high-quality waterproofing layer, and is suitable for processing large areas, exhibits excellent adhesion to the surface.

The use of the material is common in cases:

• arrangement and repair of roofs in any condition, including outdated coverings;
• as a waterproofing layer of floor slabs;
• when working on waterproofing terraces, balconies, attics;
• waterproofing of underground premises, car parks;
• to provide anti-corrosion protection structures made of stone, concrete, metal.

Protective polymer coatings fully comply with the safety requirements for roofing materials. Liquid rubber is stable, non-toxic, odorless, does not contain flammable components, and is safe for transportation and long-term storage.

Basic properties:

• quick drying of the layer;
• increased elasticity;
• seamless styling;
• soundproofing properties;
• adhesion;
• reliability and durability.

Features of applying liquid rubber

One-component liquid rubber for roofing is applied manually, and a two-component composition is applied using specialized two-channel equipment, that is mechanized way. The mastic is applied in layers, the thickness of each layer being 1 mm. Intermediate drying of each layer is allowed.

Depending on the classification of waterproofing roofing material the method of applying it to the surface is selected:

1. Bulk. Characteristic for manual execution. The polymer-bitumen mixture is poured over the area and leveled. You first need to saturate the base with bitumen emulsion and apply a primer layer. Liquid roofing is evenly distributed using construction rollers. The layer reaches a thickness of no more than 2-3 mm. After it dries, it is recommended to apply the next, final one.
2. Sprayable. The peculiarity of the method is that it is most often used in flat roofs oh and with a significant bias.
3. Painting. It is carried out by the manual application method, in which the composition is evenly distributed using special construction rollers, brushes, and spatulas. A primer is used as the first layer, after which liquid rubber is applied. The main layer of material is applied only after completely dry previous one. When spreading the coating, use a wide spatula. It is necessary to monitor the thickness of the layer - it should be no more than 3 mm.

After any method of applying liquid rubber, it takes two days for the coating to dry completely.

For roof waterproofing, priming is also used, which means applying a thin layer liquid component“A” for reliable adhesion to the base. Spraying material – mechanical method roofing treatment. The surface is pre-prepared. A special installation with a tank containing calcium chloride as the main hardener is connected to the container with the emulsion.

For installation roofing structures For different configurations, it is recommended to use a bitumen-polymer emulsion of two-component and one-component composition, depending on the type of surface.

The use of liquid rubber for roofs with a vertical, pitched or flat surface to form a seamless membrane is due to the good viscosity and non-fluidity of the composition even at high temperatures.

Useful video about applying liquid roofing

The main task of roofing coverings is to protect roofs from precipitation in the form of snow, rain, hail and others. weather phenomena. Liquid roofing is considered one of the most common and effective materials providing reliable protection from exposure to bad weather.

What is liquid roofing (liquid rubber)?

Liquid roof ( waterproofing mastic) is an integumentary waterproofing material a new generation, which is produced on the basis of latex and bitumen emulsion. When applied, liquid roofing begins to harden almost instantly, transforming into a seamless and elastic membrane.

There are no restrictions on the size or configuration of the roof for the material: the larger the area to be treated, the easier and faster it is. roofing works. Liquid rubber easily covers even complex, relief parts of the roof: parapets, pipes, ledges and canopies.

The material is intended for application to the following types roofing surfaces:

• Prefabricated and monolithic reinforced concrete.
• Slate.
• Metal.
• Natural wood.
• Cement strainer.
• Roof tiles.
• Roll materials.

Thanks to cold technology application, liquid roofing is considered more practical and versatile in use than roll and membrane coatings. Liquid rubber is used not only to protect roofs during the construction of new buildings, but also to protect buildings during reconstruction or repair work.

Types of roofing mastics, general characteristics of liquid roofing

Provided to the building materials market a wide range of roofing mastic. Based on their composition, they can be classified into two main types:

• Multi-component.
• One-piece.

Multi-component mastics include several components; if the mastic consists of only two elements, then it is considered two-component. The composition of each multi-component mastic must include a curing catalyst and a base component. The group of one-component mastics includes materials specially combined in the proportion required for hardening and application.

Liquid rubber belongs to the group of two-component mastics, but the term itself does not convey the essence of the material, as it is erroneous. Liquid roofing only superficially resembles rubber (in color, consistency and water resistance), the base of this material It is not rubber, but bitumen. Therefore, many foreign manufacturers of liquid rubber are in favor of renaming the material into a coating for sprayed seamless waterproofing.

Properties of liquid roofing

The basis of liquid rubber is a bitumen-polymer water emulsion, which allows minimizing the evaporation of toxic substances during application of the material. Liquid roofing is absolutely safe for environment and people, with its help you can put the facility into operation in as soon as possible, since the material is quick and easy to apply.

Liquid roofing is characterized by low fluidity, so it can be used to treat not only horizontal and flat roof surfaces, but also vertical surfaces. The material retains its protective properties even when high temperature, does not deteriorate under the influence of ultraviolet irradiation and moisture.

Depending on the bitumen used in the manufacturing process and polymer additives, as well as a specific manufacturer, the lowest bending temperature values ​​on a beam can be up to twenty degrees. Special varieties of material are also produced, designed for roofing in particularly cold areas of the country (with temperatures down to minus sixty degrees).

Over the years, bitumen ages and appearance changes because it contains evaporated substances essential oils. However, such negative consequences can be avoided by purchasing mastics containing polymer to create a special film that effectively prevents bitumen from aging. Polymer material extends the service life of liquid rubber to twenty years or more.

Another property of the material is increased elasticity and strength, which prevent the liquid roof from peeling off even with sudden temperature changes, changes in humidity levels, pressure and intense vibration. The use of liquid rubber is cost-effective and effective, as it allows homeowners to avoid further maintenance of the treated roof. If necessary, liquid roofing can always be repaired or restored.

The material is also resistant to various types impacts of a mechanical nature, fireproof, resistant to the influence of most aggressive chemical solutions that are used in the construction process. If desired, liquid rubber can be combined with water-based paints, which will allow you to give the roof any color.

Types of liquid roofing

There are three main types of material:

• Bulk: formed and prepared directly at the site of waterproofing work.
• Sprayable: applied by cold spraying using special equipment, is considered the classic and most common type of liquid roofing due to the ease of application and high quality of the created coating.
• Painting: waterproofing is carried out by manually applying paste and liquid film-forming materials with a brush, spatula or brush.

Liquid roofing process

Liquid roofing can be applied using cold spraying, painting or pouring technology. Regardless of the chosen work technique, it is necessary to clean and prepare the base:

• Eliminate slate chips and other granular coatings from old roofing.
• Remove loose roofing felt.
• Take out the trash and remove dirt.
• Remove dust from the surface being treated.

The base of a flat roof is first checked for the presence of stagnant zones and, if necessary, the slope is corrected (especially in places where rain or melt water drains). It is also necessary to seal the junction of the roof with parapets, ventilation ducts, pipes and other structures protruding beyond the treated area. If the material is applied on top of old roofing felt, then it is necessary to install deflectors that are designed to eliminate moisture from the roofing pie. If necessary, the waterproofing layer is reinforced with geotextiles.

Loading technology

The base is impregnated with bitumen emulsion, maintaining the thickness of the primer layer within one to two millimeters. Then the pre-prepared liquid roofing is poured onto the treated surface in portions, distributed evenly using a special roller and leveled to two to three millimeters in thickness.

Latex-bitumen mastic begins to harden within a few seconds, but it is necessary to keep the poured layer for at least five minutes. After which you can begin applying the second layer (finishing).

By using bulk technology you can level the treated roof as much as possible, but for pitched roofs he doesn't fit.

Dyeing technology

For the first layer, prepare a solution consisting of water (no more than 30%) and rubber, which is evenly distributed over the base using a roller or brush. The time required for the first layer to dry completely depends on the ambient temperature. So, at a temperature of +5 you will need to wait at least two to three hours, and at +20 degrees - one hour. After this, the finishing layer is applied, and there is no longer any need to dilute the liquid rubber with water.

The material is applied to the surface with a spatula or a wide brush in a layer of two to three millimeters, after which you will need to wait at least 48 hours until the material dries completely. It is recommended to apply the second layer perpendicular to the direction of application of the first layer in order to evenly treat the roof with the material.

Dyeing technology suitable for processing pitched roofs and small-area roofs, when the use mechanical devices not economically justified.

Sputtering technology

The essence of this technique is that liquid rubber is sprayed onto the treated area using a special airless apparatus connected to two containers at once: one containing a bitumen-polymer emulsion, and the other containing calcium chloride as a hardener. Both components simultaneously enter the nozzle, where they are mixed and then applied. As a result, a polymer-bitumen membrane for waterproofing, two to four millimeters thick, appears on the treated roof. The liquid rubber applicator can be powered by either an electric or a gasoline drive.

Spraying technology is suitable for treating sloping roofs and large roof areas.

Advantages of liquid roofing

The material has the following important advantages:

• Long service life.
• Resistance to negative influence ultraviolet radiation and aggressive chemicals.
• Possibility of storing material in liquid state in barrels.
• When carrying out repair work, liquid roofing can be applied to the old coating.
• Cold spray technology allows the use of liquid rubber on roofs of any area and geometric shape.
• Liquid roofing has high adhesion to most building materials.
• Cost-effective: processing one square meter will require from one to three kilograms of liquid roofing.
• After treating the surface with liquid rubber, even the most complex roofs have no seams.
• When carrying out waterproofing work, there is no need to use electricity, fire or water.
• Absolute safety for the environment and humans.
• Liquid roofing provides high degree elasticity and strength of waterproofing.
• The substance is not subject to corrosion and aging.
• After treating the roof, all holes, cracks and holes that can allow moisture to pass through are eliminated, so the roof becomes completely waterproof.
• The coating created using liquid roofing is resistant to high and low temperatures and sudden temperature changes.

Flaws

The disadvantages of the material include:

• Increased sensitivity of liquid roofing to oil-containing solvents and substances, the effects of which must be completely eliminated.
• Possibility of removing the coating only mechanically.
• High cost of material.

Liquid roofing is a universal and practical material, which is perfect for processing any roof shape, configuration and characteristics.

The use of liquid sprayed or spreadable waterproofing compounds when repairing or arranging roofs is an excellent alternative to any modern materials. They provide unique indicators of tightness, adhesion to the base, strength, resistance to wear and ultraviolet radiation. The only operational drawback is the difficulty in dismantling, the general one is the high price (from 300 rubles/m2), other indicators are superior or not inferior soft roof. Applied manually or mechanized, the products are freely available.

Description of the material, scope of application

The term “liquid rubber” is not entirely accurate; the basis here is modified bitumen and polymers, not rubber. It was coated due to the high elasticity of the film formed after drying and its absolute waterproofness. Characteristic parameters include the absence of seams, environmental friendliness, resistance to corrosion, biological and mechanical influences and UV, high adhesion and the ability to restore the structure of rolled bitumen products.

The scope of use of this type of roofing covers new and reconstructed surfaces made of monolithic and prefabricated reinforced concrete, metal, screeds, slate, wood, rolled materials and all types of tiles. The angle of inclination does not matter, but the maximum economic effect is achieved when processing large areas of flat roofs (including those in use) and when implementing projects with a complex configuration and a large number of connections. Liquid rubber is indispensable when necessary quick fix damage or sealing of any seams and joints. The only limitation is the difficulty or impossibility of dismantling; some brands penetrate deep into the base and are removed only with the help of chemical dissolution.

Types and characteristics

Depending on the composition and method of application, the following are distinguished:

1. A two-component liquid spray roofing consisting of a bitumen-polymer emulsion and a hardener, combined cold or hot. This type is installed using airless sprayers and its use is clearly justified when covering areas over 100 m2.
2. One-component, direct-applicable primers, mastics and gels with polymer additives. Sold both in buckets and in small containers. The latter are justified when carrying out repairs or restoration, sealing individual adjacent structures, and eliminating defects.

Depending on the performance characteristics, they are conditionally divided into:

1. Conventional grades, installed at positive temperatures, and all-season grades, installed in any weather.
2. Emulsions sprayed in liquid form and more viscous mastics spread over the roof with a brush, roller or trowel.
3. Tinted or single-color stamps.
4. Conventional or improved with polymerization accelerators and other modifiers.

Review of popular brands

TO distinctive features include the presence of modifying additives that eliminate the impact of biological threats on protected structures. The declared service life is 15 years.

Cost of liquid roofing materials

Arrangement liquid waterproofing roofs – effective method protecting the building from moisture, precipitation, low temperatures and other environmental factors. You can do a liquid roof with your own hands, and in this article we will talk about how to do such work.

The unfavorable climate that prevails in many regions of our country leads to the fact that many Construction Materials over a short period of time they lose their operational properties. Low temperatures and sudden temperature fluctuations can deform the roofing. Thus, roofing felt and other similar products quickly become unusable, losing their ability to waterproof.

Among modern, higher quality and durable materials You can highlight liquid rubber for roofing. It is applied to the surface in a “cold” way, that is, without heating, which significantly simplifies the work process. This type of roofing is characterized by increased strength, it is seamless, elastic and can last much longer than sheet and roll waterproofing. The cost-effectiveness of the coating is associated with this quality, although it costs significantly more than the same roofing material. But, unlike roofing felt, it does not have to be repaired every 1-2 years; liquid rubber lasts for decades without bursting, cracking or breaking.

Advantages of roof waterproofing with liquid rubber

1. Liquid rubber allows you to create a monolithic coating on the surface without a single seam. It has not only no joints, overlaps or seams, but also microcracks through which moisture can enter. roofing pie and spoil the underlying materials.
2. Most roll materials are installed on the roof by heating. If you do not heat the sheet itself, then be sure to melt the mastic on which it is glued. And on some construction sites For one reason or another, the use of fire is not permitted. With liquid roofing, which is applied to the surface in a “cold” way, such a problem will not arise.
3. Liquid rubber has increased elasticity, which allows it to withstand temperature changes, the range of which is from -50 °C to +100 °C. Even with such unfavorable conditions the material does not peel off, does not deform, does not crack or even soften.
4. Quick repair of liquid roofing is another of its undoubted advantages. Even if damage occurs on the surface for some reason, they can be patched with the same composition, but in the case of rolled material you will have to change an entire fragment of the sheet.
5. Repairing a liquid roof is also simple because it is very easy to detect a leak and repair it immediately. On rolled products, damage is not so noticeable and is more difficult to determine.
6. Liquid rubber for roofing allows you to work with complex objects and areas, such as gutters, shafts and vertical elements. It is much easier to apply it to such areas, but roll material will have to be cut and laid in a certain sequence.
7. This type of waterproofing is highly durable; moreover, it can be further increased by adding a special coating between the layers of coating or laying a glass mesh.
8. Rolled materials should never be laid on a wet roof, otherwise they will quickly peel off. With a liquid roof, this requirement is not necessary, since the rubber adheres well to almost any surface.
9. Liquid roofing waterproofing can be used in combination with roll products.
10. Liquid rubber is used to waterproof surfaces not only outside, but also indoors, and its installation is much easier and faster than roll coating.
11. The water-repellent properties of the material in question are much higher than those of other analogues.
12. Liquid roof waterproofing has a small mass and does not exert a noticeable load on the floors of the building. Rubber consumption is approximately 1.5-2 kg per 1 m², while a layer 1.5-2 mm thick is created on the surface.
13. The ease of working with the material lies in the fact that you do not need to cut sheets and perform a certain laying sequence, creating reinforcing layers. Using the liquid rubber spraying method, an area of ​​600 m² can be covered in 1 day.
14. You can subsequently paint a roof waterproofed in this way in any shade you like.
15. This mastic hardens very quickly. Strong adhesion to the base occurs in less than 1 minute, and after half an hour the roof can withstand minor physical impacts, for example, you can walk on it.
16. Liquid roofing is not afraid of ultraviolet radiation; it is resistant to most chemicals, is not damaged by salt water, alkaline and acidic compounds, gasoline, oils. It does not harbor microorganisms or mold.

Liquid waterproofing for roofing requires minimal labor and time, and although it costs more than many other materials, its longevity will more than pay for all costs.

Areas of use of liquid polymer roofing

1. Most often, waterproofing of this type is used in the construction of residential and industrial facilities. Because liquid polymer coating has increased strength, it can be used on roofs that will subsequently be actively used. For example, on such a roof you can arrange a parking lot, create a garden, a recreation area, etc.
2. With the help of such mastics, soft roofs can be restored.
3. Liquid rubber is convenient to use for waterproofing difficult areas: ventilation ducts, chimneys, parapets, pipe exit points, etc.
4. Using such compositions, you can waterproof balconies and loggias, as well as canopies.
5. Polymer mastics are indispensable for industrial buildings, especially where fire cannot be used when laying rolled materials.

Types of liquid roofing

Based on the number of components that make up the material, the following types of liquid rubber are distinguished:

1. One-component - is a multi-color mass that does not require advance preparation and can be used immediately.
2. Two-component is a composition that includes a base and a special hardener. Its components are mixed before application.

According to the application method, the material can be:

1. Painting - applied to the surface using a brush or roller, like regular paint. Most often it is a liquid or paste-like mass.
2. Sprayable - this type of rubber is a liquid that is supplied through a special installation and quickly sprayed onto the working base.
3. Bulk - this mass is prepared immediately before work, then poured onto the roof area and leveled.

With the sprayed or poured method, rubber penetrates into the smallest cracks, pores and cracks, closing them from moisture penetration and creating very durable and reliable protection.

Methods of applying liquid waterproofing

Mechanized method

Depending on the availability of materials, tools, devices, as well as technical capabilities and type of coating are determined by the method of applying liquid waterproofing. This can be done manually or using a special airless injection unit. It should be noted here that working with it requires certain skills and abilities, and if you are not sure that you are capable of such work, then it is better not to risk it and apply the coating manually.

The installation is convenient in that during operation it immediately mixes all the components of the mastic into the right proportions, and then supplies them as a sprayed mass. High pressure, which is approximately 18 atmospheres, allows the solution to penetrate into the smallest pores and microcracks. Polymer mastic sets on the surface almost immediately after application.

The mobile unit allows you to significantly speed up the work process. It is also useful in that it minimizes material consumption and makes it the most economical. The thickness of mastic application directly depends on the type of roof. Membrane roofing needs waterproofing with a layer of 2-3 mm, metal and wood coatings can be treated with a layer of 1.5 mm, but for concrete the ideal figure would be 3 mm or more.

The process of creating a liquid roof consists of the following sequence of actions:

1. First, the roof is measured and, based on the surface being treated, the amount of material required is calculated.
2. Then they purchase the product, paying attention to its quality. It is advisable to buy polymer mastic from trusted manufacturers at specialized sales points.
3. After this, the roof surface is prepared for work, and then the mastic is applied to the base.
4. The tightness and evenness of the layer is checked and, if necessary, defects are corrected.

ABOUT the right amount It is better to discuss the material separately. There should be enough mastic to cover the entire roof. If there is not enough of it, there is nothing wrong with that, but it is inconvenient to purchase additional material during the work process. At the same time do large stock when purchasing it is also not worth it, since mastic is not cheap, and this will entail unnecessary additional expenses. To find out for sure how much rubber you will need, measure your roof and calculate its area. Then find out the approximate material consumption indicated on the packaging. Based on these data, calculate the amount of mastic you need. If the packaging does not contain the necessary information, then be guided by these figures: 1 kg of the substance is usually enough to cover 4 m² of area if applied in 2 layers.

Applying mastic manually

If the roof is small and mobile installation If you don't have one, you can apply mastic manually. For this work, a brush, roller or spatula is used. Let’s say right away that this process is labor-intensive and time-consuming, so you need to calculate own strength and time. But manual application is accessible to everyone and does not require any special skills.

The work process looks like this:

1. It is better to apply mastic in good weather when it is not too hot, there is no rain and fog. The ambient temperature must be at least +5 °C.
2. Preparation of the working base involves the removal of all foreign objects from the roof surface, as well as cleaning it from debris and dirt. If there are weak and flaking layers of the previous coating on the base, these also need to be removed. Noticeable defects are corrected using cement-sand mortar or other means suitable for this type roofs. If you are restoring previously applied rubber cover, then clean the treated area with coarse-grained sandpaper, then cover the area with mastic and adjust it flush with the rest of the surface.
3. So that the rubber is guaranteed to adhere to roofing covering, oil and others greasy spots also worth removing.
4. Cold mastic is applied to the surface with a wide roller or large brush, creating a layer of 3-4 mm.
5. As a rule, waterproofing is applied in 2 layers. The first layer is allowed to dry for 10-15 minutes, during which time the rubber is completely polymerized and thoroughly adheres to the working base.
6. After this, perform the second layer in the same way. In some cases, 3 layers of coating are made, leveling out all differences in height during the application process.
7. A finishing coating can be applied on top of the finally hardened mastic.
