Consumption of liquid rubber per 1 m2 waterproofing. Liquid rubber waterproofing business. Materials for waterproofing according to the technological map of the roof

Example 1 There is a foundation of a cottage under construction with a perimeter of 150 meters and a height of 3 meters.

The design is characterized by a complex perimeter geometry. Also, shells with a depth of more than 1 cm are noted on the foundation (they are formed during poor-quality formwork pouring of concrete). The total area of ​​the sinks is 10 m2. Also, the presence of four joints of the foundation slabs along the vertical and complete adjoining of the junction of the foundation walls to the foundation lens. The foundation also has 8 corners at 90 degrees (i.e. sharp corners).

Foundations of any type, especially of complex geometry (and there are now the majority of such foundations, because projects often include wine cellars, billiard rooms, swimming pools, etc.) - this is the work that can be done quickly and efficiently only with the help of seamless spraying technology waterproofing liquid rubber.

Scope of work for this object:

The total area of ​​the foundation is 450 m2, of which 150 m2 is at a depth of more than 2 meters;
The total area of ​​shells with an average depth of 1 cm is 10 m2;
The total area of ​​joints, corners and junctions is 4x3m (linear footage of joints of foundation slabs vertically) + 150m (linear footage of junctions at the junction of foundation walls to the foundation lens) + 8x3m (linear footage of 8 corners of the "type" 90 degrees) = 12 + 150 + 24 = 186 m2.

Applied equipment (prices as of autumn 2015):

RX-28/220V installation (the choice is due to the lack of 380V power supply on the site). Cost - 168,500 rubles;
Overalls, electric stirrer, working tools - according to the list of additional equipment and accessories for the RX-28/220V unit. The cost is about 11,500 rubles.

TOTAL equipment - 180,000 rubles.

Raw materials and consumption of materials (prices as of autumn 2015):

Two-component waterproofing system "Liquid Rubber for underground structures" - 300m2 x 3l/m2 (foundation waterproofing at a depth of up to 2 meters) + 150m2 x 4l/m2 (foundation waterproofing at a depth of more than 2 meters) + 450m2 x 0.5l/m2 (preliminary priming waterproofed surface) = 900l + 600l + 225l = 1775 liters. Cost 1775l x 125 rubles / l = 221875 rubles;
Calcium chloride, 2 bags of 25 kg (based on 1 bag per 1000 liters of "Liquid Rubber"). The cost of 2 bags x 1000 rubles / bag = 2000 rubles;
Geotextile substrate - 0.2m (width of the reinforcing strip) x 186m2 (total area of ​​"dangerous" places) = 37.2m2. Cost 37.2m2 x 20 rubles / m2 = 744 rubles;

TOTAL for raw materials and materials - 224619 rubles.

Time required to apply liquid rubber:

Embedding and waterproofing sinks 10 m2 - 2 hours.
Preliminary priming of the waterproofed surface 450m2 x 0.5l/m2 = 225l - 30…45 minutes (taking into account possible stops).
Rolling of geotextiles in "dangerous" places of joints, corners and junctions: 0.2m (width of the reinforcing strip) x 186m2 - 3 hours (slowly and efficiently).
Application of liquid rubber 1500 l. - 3.5 ... 4 hours.

TOTAL for the time spent: 9 ... 10 hours.

Economic evaluation of roof waterproofing with liquid rubber.

The reliability and durability of flat roofs is guaranteed by the use of modern building technologies and materials, such as liquid rubber. Such roofs are distinguished by: water resistance, incombustibility, ease of installation and maintenance, and long service life.

With regard to soft roofs, there are 2 types of work:

1. Overhaul roofing - includes the complete removal of the old waterproofing (usually: ruberoid) coating, repair of the screed, laying a new roofing carpet.
2. Current repair of the roof - consists in replacing defective sections of the old roofing material, sealing holes and cracks and laying new material.

Example 2 Capital repairs of a flat roof.

Number of aerators 1-2 pcs. for 50-100 sq. m. The cost of one standard roof aerator is 700 rubles per piece. The cost of its installation is 350-400 rubles per piece.

In places of swelling, a cross-shaped incision should be made (opening with an “envelope”), the panel should be bent, the base should be thoroughly cleaned, dried with a gas burner flame and mastic should be applied both to the base and to the carpet panel. Then the bent edges of the carpet are returned to their place and pressed. For this operation, it is advisable to use ready-made cold mastics.

The cost of one-component mastic is 250 rubles / kg, consumption is 1.5-2.0 kg / sq. m.

Places where the roll material is completely rotted must be cut out. Thoroughly clean the resulting recess, fill with cement-sand mortar.

The more accurate the cutting will be, the less it will be necessary to repair the screed. To repair a cement-sand screed, a solution of a grade of at least 150 is used. After 8-10 days after laying, the screed is primed. Bituminous polymer mastic (liquid rubber, without hardener) is used as a primer.
Consumption 0.5 kg per 1 sq. m, the price is 125 rubles / kg.

Reinforcement increases the strength, but reduces the elasticity of the mastic coating, so it is necessary to understand what is preferable for a given roof. Reinforcement can be performed only in individual nodes (usually adjunctions and mates).

Reinforcement is done as follows. A thin layer of liquid rubber is applied by spraying (without hardener), with a consumption of 0.3-0.5 kg geotextile is laid and rolled to ensure a snug fit to the base over the entire surface, then a thin layer of liquid rubber is applied on top - consumption of 0.5 kg / sq m for impregnation of geotextiles, exposure to complete drying 2-5 hours.

After carrying out all the above works, the installation of the main waterproofing coating (liquid rubber) is carried out.

Bitumen-polymer mastic is applied by spraying, for this work, equipment of the RX series for liquid rubber is used.

The consumption of bitumen-polymer mastic is 3.0 kg per 1 sq.m to provide a waterproofing layer of at least 2 mm.

The cost of 1 kg is 155 rubles.

Example 3 Repair of a flat crawl of an industrial building 20x30 m.

The total coverage area is 600 sq. m.
Old roofing material. There are swellings on the roof with a total area of ​​100 sq m.
When removing (cutting out) swellings, depressions 30 mm deep were formed.

Today, in the "do it yourself" section, we will look at how to independently repair a soft roof with your own hands - bituminous coatings, roofing material, euroroofing material, PVC and EPDM membranes- Alchimica trademark materials (Greece). We note right away that not every old waterproofing coating can be covered with liquid rubber.

Photo 1. Bad roof	Photo 2. Good roof

In the photo, both roofs are leaking. But, in photo 1, the old waterproofing is subject to complete dismantling, followed by repair of the roofing pie. And in photo 2 - the old coating is a good basis for applying liquid rubber.

Do-it-yourself soft roof repair - Technology and stages of work

1. Surface cleaning

The surface must be clean - free of dirt and dust debris, for this you can use a broom, brush or industrial vacuum cleaner.

2. Surface repair

1) Cut out rotten and water-soaked areas (if any) ➔ seal with repair mortar flush with the old waterproofing.
2) Cut the places of roofing material swellings crosswise ➔ open the roofing material ➔ let the screed dry (if the screed needs repair, it must be done) ➔ apply a layer on the screed (consumption 0.6÷0.9 kg/m.kv) ➔ drown (glue) ruberoid.
3) Carefully inspect the seams and junctions of the old coating.
4) Reinforce repair areas, seams, junctions: apply Hyperdesmo AshAA to the repair area at a rate of 0.6 kg/m.sq.
5) For defective seams, and junctions, also perform reinforcement. Small cracks-slits can be sealed with sealant.

3. Applying waterproofing (1st layer)

Apply only to dry and clean surfaces. Hyperdesmo AshAA can be applied with a brush, brush, roller (short and medium bristles) or airless sprayers (operating pressure > 200 bar). The consumption of Hyperdesmo AshAA mastic should be 0.7 ÷ 1 kg / sq.m, for this you can conditionally divide the area into small sections, and roll out the bucket in sections.

4. Application of waterproofing (2nd layer)

The application of the second layer is possible as soon as the first layer can be walked on (6÷48 hours). Before applying the second layer, carry out visual inspection(control) of the surface, on the subject of how the first layer lay down. If small cracks, crevices, “holes” are detected, seal them with Hypersil 25 LM sealant ➔ apply a second layer of Hyperdesmo AshAA liquid rubber with a flow rate of 0.7÷1 kg/sq.m.

The total consumption of Hyperdesmo AshAA for bituminous, ruberoid, roll coatings should be 2 kg / sq.m. If you applied waterproofing along the upper boundary (1 kg / sq.m), then you reach a total consumption of 2 kg / sq.m when performing work in 2 layers. If you walked along the lower border (0.7 kg / sq.m), then you still have to apply the third layer. We recommend the second option (three layers of 0.7 kg/m2). Yes, in this option, the time to complete the work increases, but at the same time, you have one more interlayer surface control.

rubber paint is an environmentally friendly, breathable coating for indoor and outdoor use. A distinctive feature of rubber paint is superelasticity, heat resistance, adhesion (sticking) to all known materials, resistance to ultraviolet radiation, resistance to adverse conditions (increased dampness, temperature changes, shock, abrasion), containment of substrate cracks.

Rubber paint is so named because the paint film is flexible and can be rolled up and bent without breaking. The paint has an unusual composition, it does not contain toxic solvents and components. The paint does not have a strong odor, does not burn, does not irritate the skin and can be used indoors without the risk of poisoning.

The paint was developed in order to obtain reliable surface waterproofing. It should be noted that in this case, the protective elastic layer has vapor permeability, i.e. will not interfere with the evaporation of moisture remaining in the structure of the painted material. At the same time, the paint retains its outstanding performance characteristics for more than 10 years.

High UV resistance and various colors allow rubber paint to be used as additional protective and decorative coating for liquid rubber.

Areas of application for rubber paint

Rubber paint is distinguished by its versatility, we note its main applications.

For waterproofing floors in rooms with high humidity (baths, showers, bathrooms, etc.). In the event of an accident, water will not penetrate through the ceiling into the lower apartment, which will save you from unnecessary expenses. And the walls and floor - will not become waterlogged during the operation of the premises.

For waterproofing outdoor concrete pools. The coating creates a film resistant to temperature extremes on the surface, which also prevents moisture from penetrating into the structure of the concrete layer.

Concrete floors in corridors, rooms adjacent to the pool, shower rooms are also often covered with rubber paint. The coating makes the surface neat and non-slip, easy to clean from dirt.

Open balconies, verandas and terraces. Moreover, the composition can be applied to both concrete and wooden surfaces.

To protect the plinth and blind areas from moisture. The paint will create a smooth, waterproof coating that allows water to run off easily without penetrating to the base of the building. This will protect the foundation from premature destruction, especially if it is built from materials that are hygroscopic.

For the repair and protection of slate roofs. As you know, slate has a rough structure, so dust and dirt can linger on its surface. Stagnant phenomena in certain areas lead to the appearance of lichens that destroy the slate coating. Therefore, more and more owners of private houses, not yet having the opportunity to change slate for more practical cover cover the roof with rubber paint. It creates a smooth protective layer so water and dust won't linger on the surface and the roof stays clean.

For the repair of a metal roof, the coating will reliably protect the metal from corrosion.

Fences made of reinforced concrete, wood and metal can also be painted with rubber paint. This layer will not only protect the surface from damage, but also give the structure an aesthetic appearance. appearance. For coating, you can choose a color that will harmonize well with the facade of the house.

Paving slabs covered with rubber paint are not destroyed by frost and water, and their excellent appearance will delight owners for many years.

The wooden surface covered with rubber paint will be reliably protected from rotting and mold formation, as well as drying out under the influence of ultraviolet rays and high temperatures during the summer period.

Another area of ​​application of rubber paint is the anti-corrosion treatment of cars, which combines both a protective and a decorative component. The rubber layer has a high resilience and elasticity, due to which the coating is insensitive to mechanical damage.

Specifications of rubber paint

Drying time "To touch"- 30 - 40 minutes, until solid 1.5 - 3 hours (depending on temperature and humidity).

Dry residue- not less than 70%.

Density~ 1.1 kg = 1 l

Shine- semi-matt.

Approximate consumption of rubber paint (in 2 layers)

Tool cleaning- water with baking soda and soap or detergent

Wash resistance- increased

weather resistance- excellent, even in an industrial environment

Storage- Protect from freezing. Store in an airtight, tightly closed container. Guaranteed shelf life in original unopened packaging is 24 months from the date of manufacture.

Toxicity- environmentally friendly, odorless.

Color- depends on the coloring.

Rubber paint technology

The paint rubber coating will serve for a long time only if the technology of its application is observed. If the rules were not followed, then you can get the opposite effect and the need to re-repair the surface.

Applying rubber paint can only be done on a previously cleaned and dry surface, at an ambient temperature of at least +5 degrees. It is impossible to carry out work in the rain, in very hot weather and in direct sunlight.

Various methods of applying paint are possible: brush, roller, spray gun.

For painting large surfaces, a roller is well suited (we recommend a velor roller with a short pile).

When using a spray gun, use a nozzle with a diameter of at least 2 mm. If the paint is too thick, then it must be diluted with soil or water (no more than 5%). The principle of applying paint is the same as when using other paints.

Coloring must be done in at least 2 layers. Splashes of paint flying from the brush must be removed very quickly with a damp cloth, preventing them from drying out. If, after the paint has dried, unpainted areas are visible on the surface of the wall, then they can be eliminated by covering them with another layer of rubber paint.

Foreword. Bitumen-polymer mastic Slavyanka is a completely ready-to-use coating waterproofing. It is a mixture of a homogeneous black mass, liquid rubber is characterized by the formation of an elastic coating after drying. Consider in the article the technical characteristics of Slavyanka mastic, the technology for applying liquid two-component rubber and the consumption of Slavyanka waterproofing per 1 square meter.

Scope of coating waterproofing Slavyanka

Photo. Coating waterproofing Slavyanka

Slavyanka® mastic is used to protect metal, concrete or reinforced concrete materials and other building structures from moisture. It is also used for processing residential premises with high humidity from the inside - waterproofing basement walls, inspection pits, bathrooms, etc. Liquid two-component rubber Slavyanka is also suitable for waterproofing pipelines, septic tanks and other containers for various purposes.

Application technology involves temperature regime from -10С to +50С, the temperature of the material must exceed +15С. For convenience, the mastic can be diluted with an organic solvent to the desired consistency, but not more than 20% of the total weight of the mixture. Since when diluting liquid rubber produced by Rastro over 20%, the technical characteristics of the resulting waterproofing film on the treated surface deteriorate.

Description of bitumen-polymer waterproofing Slavyanka

Mastic Slavyanka® coating waterproofing, manufactured by Rastro, is a one-component, ready-to-use bitumen-polymer composition. Technologists production company"Rastro" is constantly improving the company's products, improving its characteristics and performance, expanding the scope of Slavyanka waterproofing, in a word, they do everything to ensure the best price-quality ratio.

Mastic Slavyanka® coating waterproofing is a bituminous-polymer composition with a pasty consistency of black color. After drying, liquid waterproofing creates a thin layer of a rubber-like membrane. During storage, sedimentation is possible, which does not affect the performance of the composition. Before use, the mastic should be mixed and, if necessary, diluted with a solvent to the desired consistency.

Advantages of waterproofing Slavyanka:

- the possibility of using mastic at low temperatures;
— good adhesive properties to any materials and high elasticity;
- chemical resistance in aggressive environments and the strength of the resulting layer;
— high viscosity allows to apply liquid rubber on vertical surfaces.

Limitations and disadvantages of Slavyanka mastic:

- it is forbidden to use bitumen-polymer mastic inside residential premises;
- it is forbidden to use in liquid organic media: oil, oil products;
- do not use as an adhesive for expanded polystyrene and materials based on it;
- Do not apply to a surface that is not cleaned of dirt, dust and grease stains.

We have considered all the pros and cons of Slavyanka waterproofing, it remains only to add that the manufacturer reserves the right to change the technical characteristics of Slavyanka liquid rubber and the technology of its application without prior notice, in order to improve product performance. The manufacturer is not responsible for defects resulting from violation of the instructions.

Waterproofing Slavyanka: technical specifications

- heat resistance up to 140 degrees Celsius;
— material viscosity from 140 mm to 180 mm;
— material elongation at break up to 1000%;
— tensile strength reaches 1.5 MPa;
— temperature of use from -10 to +50C.

Table. Specifications waterproofing Slavyanka

Work should be carried out in well-ventilated areas, away from sources of fire or in the open air, since the composition of the mastic includes flammable substances. If the mastic gets on the skin, it is necessary to remove the composition with a cloth, then the coating waterproofing Slavyanka should be washed off with soap and water. Application technology prohibits the use bituminous mastic inside living rooms.

Waterproofing Slavyanka: application technology

It is more convenient to apply mastic on a vertical surface with a roller, brush or spray method. On a horizontal surface, for example, when waterproofing flat roofs, it is possible to pour the mixture with subsequent leveling over the surface with a mop or spatula. Foundations that require backfilling with soil can be backfilled after the mastic has completely dried to prevent damage to the layer.

Preparing the surface for applying mastic

As in the case of independent use of TechnoNIKOL coating waterproofing, the surface to be treated should be cleaned of dirt, rust, grease stains and similar contaminants. If necessary, repairs are carried out, all chips and cracks on the concrete surface are sealed before applying the mastic. Then the surface is dried and liquid rubber is applied to it with a brush or by spraying.

If necessary, another layer of insulation is applied to the dried first layer. The thickness of the finished layer should be no more than 2 millimeters. In hot weather, the mastic is applied in 4-5 passes, in layers of no more than 0.5 mm. One hour after application, the coating resists rain, but the final cure time of liquid rubber depends on the material of the treated substrate, weather conditions and the thickness of the waterproofing layer.

Waterproofing Slavyanka: consumption per m2

Average consumption of Slavyanka® mastic per 1 sq.m. when creating a layer with a thickness of 1 mm, it is about 1.39 kg / m² (1.39 kilograms of the finished mixture per 1 square meter of the treated surface). To accurately calculate the amount of material needed, use online calculator waterproofing costs on our website. Next, watch the video, applying liquid two-component rubber to a flat roof.

The use of liquid sprayed or spreadable waterproofing compounds in the repair or arrangement of 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 disadvantage is the difficulty in dismantling, the common one is the high price (from 300 rubles / m2), other indicators are superior or not inferior soft roof. applied by hand or mechanized way products are freely available.

Description of the material, scope

The term "liquid rubber" is not entirely accurate; the basis here is modified bitumen and polymers, and not rubber. Its coating was obtained due to the high elasticity of the film formed after drying and its absolute water tightness. The 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 this type of roofing includes 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 flat roofs(including those in operation) and in the implementation of projects with a complex configuration and a large number of connections. Liquid rubber is indispensable when it is necessary to quickly repair damage or seal 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, there are:

1. Two-component liquid sprayed roofing, consisting of a bitumen-polymer emulsion and a hardener, joined in a cold or hot way. This type is applied with airless sprayers and is clearly justified when covering areas over 100 m2.
2. Single-component, direct-applied 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. Ordinary grades laid at a positive temperature, and all-weather grades, mounted in any weather.
2. Emulsions sprayed in liquid form and more viscous mastics spread over the roof with a brush, roller or spatula.
3. Tintable or single color stamps.
4. Regular or enhanced with polymerization accelerators and other modifiers.

Overview of popular brands

• LKM CCCP.

It has a universal scope, it is recommended to purchase both for repair and full protection of any roofs, including those in operation. It is applied manually or mechanically, forming after drying an elastic, seamless coating, characterized by excellent resistance to moisture, ultraviolet, temperature extremes from -70 to +100 °C, mechanical stress and cracking. It has high adhesion to any surfaces and complies with standards fire safety(combustibility group G1). The advantage over other brands and analogues is the possibility of tinting in any desired color with the original white and the addition of natural cork in order to improve the insulating and decorative properties.

• Blockade.

The line for outdoor work from the leading manufacturer of insulating materials LLC IK "Voskhozhdenie" is represented by ready-to-apply polyurethane compounds, which after drying form a strong, highly adhesive and resistant to most external influences film. Reviews of blockade waterproofing are extremely positive, its advantages include a high proportion of dry residue (up to 98%), low consumption, no cracks when the layer dries for 6 hours, providing additional anti-corrosion protection and resistance to abrasive substances and mechanical damage. This line includes both universal and specialized waterproofing mixtures.

If it is necessary to repair or process at sub-zero temperatures, an all-weather coating is used; if you want to speed up the polymerization process, you can buy a mastic with a hardener.

• Two-component liquid rubber Technoprok.

It is sprayed on the surface with the help of special equipment, its use is optimal when it is necessary to finish large areas, including exploited roofs. It is valued for economical consumption (one 200 l barrel is enough for a roof of 60 m2), affordable cost, good extensibility and recovery, fire and environmental safety and high installation speed. Despite the need for a catalyst addition, this type of coating is not heated, the use of special techniques eliminates any dilution and application errors. As a result, a team of several people processes at least 1000 m2 in 1 shift. After quick drying, a seamless film with good strength, moisture and sound insulation properties is formed.

Another two-component type of bitumen laid with airless installations, characterized by exceptional hydrophobic abilities. It is used for roofs of any complexity, foundations, floors in rooms with high humidity and even pool bowls. This brand is 10-20% more expensive than analogues, which is explained by good resistance to wear, ultraviolet radiation, mechanical stress and long service life. The warranty is 5 years, the durability reaches 25.

• Fast repair.

The uniqueness lies in the absence of application restrictions: a one-component primer is applied to the work surface in any condition, regardless of weather conditions. When waterproofing large areas, it is distributed by the bulk method and shows good results in terms of wear resistance and durability (guarantee for protective qualities is 12 years), but the maximum effect is achieved when repair work and elimination of defects. Thanks to its gel-like consistency, this type of liquid rubber for roofing covers difficult areas, including vertical and holes up to 3 mm. The second feature of the brand is the ability to displace moisture and completely fill the pores of the base, up to restoration. useful properties old soft coverings.

This finished variety is recommended to be bought when processing interpanel joints and roofs of residential, public, administrative and industrial facilities. With high demands on the cleanliness of the plane and weather conditions, Corundum is valued for its unique adhesion to any surfaces and efficiency, the consumption does not exceed 1.2 kg per 1 m2. The distinctive features include the presence of modifying additives that exclude the impact of biological threats on protected structures. The declared service life is 15 years.
