Covering for tennis courts. Hard coating Types of tennis courts

Coating hard — seamless system of arrangement of functional, acrylic layers that create hard tennis surface physical characteristics such as ball bounce, speed, roughness when playing professional and amateur tennis. Hard coating for tennis courts is an all-weather, environmentally friendly coating WithITF certified - international tennis federation. Hard court surface divided into pure and softened hard. Softening hard is achieved in two ways. The first method: adding rubber granules of various diameters to the acrylic layers. Second, a rubber backing (such as Regupol 7210, Sportmat GF 730, Kraiburg 6015 N) is glued to the base with 2-component polyurethane glue, onto which it is poured layer by layer hard coating.

The advantages of the hard drive include a long service life, a variety of colors that do not fade over time, and an anti-reflective coating system. A diagram of possible color combinations is below.

Hard for multifunctional sites

Becoming popular hard coating for multifunctional grounds with combined sports such as mini-football, basketball, badminton. The surface of the Hard Play coating is smooth and has no roughness, unlike the classic one. hard, in the layers of which rounded quartz sand is added. Hard Play is an excellent alternative to a seamless coating made of crumb rubber, which has a higher coefficient of friction and is “heavier” for playing mini-football and basketball.

Substrate requirements for tennis surfaces

Reliability and quality expressed in long-term operation tennis court surface consists of preparing the foundation. This is the most important stage in preparing a tennis court. An asphalt concrete base for a hard drive has a number of basic requirements:

  • the foundation should be placed in soils that exclude the possibility of deformation;
  • the surface slope should be 1%, drainage trays;
  • the surface should not have potholes, cracks, protrusions, or sagging;
  • the evenness of the base is controlled by a three-meter strip laid in any place and direction; the clearance should not exceed 3 mm.

Detailed requirements for asphalt base hard coverings

The concrete base for subsequent laying of the hard tennis surface has the following requirements:

  • height not less than 120 mm;
  • concrete class for compressive strength M 300;
  • slope 1%, drainage trays, temperature-shrinkable seams;
  • humidity no more than 4%;
  • polished surface.

  • Hard Pour (pure hard)

System "clean" hard court surface - budget coating which includes Primer C 961 L, resurfacer, base. Apply from 3 to 6 layers, without any softening layers Cushion, Ultracushion. IN tennis surface"clean" hard add quartz rounded sand, depending on the selected technical characteristics coating, the amount of quartz sand is reduced to make the court faster or, on the contrary, increased to slow down the game. "Pure" hard, like other types of sports surfaces, winter time The snow cover is first poured under the skating rink.

  • Hard Soft (softened hard)

softened hard coating for tennis courts Suitable for outdoor, indoor tennis courts. Provides a comfortable game and better shock-absorbing properties compared to hard hardboard due to the content of special layers in the acrylic emulsion - Cushion and Ultracushion, which containrubber and EPDM granules. Softened hard is laid in 7 to 14 layers. Operation does not require special care. In winter it hides under the skating rink.

  • Hard SuperSoft (hard with rubber backing)


Hard coating SuperSoft on rubber shock-absorbing backing such as Regupol, Kraiburg, Sportmat— b seamless acrylic system tennis court coverings, giving players maximum comfort when playing by reducing the load on the joints and spine. The rubber backing is glued to the prepared base(according to the requirements presented above on this page) two-component polyurethane adhesive. In the winter season, the site is filled with a skating rink.

Next, the program analyzes previous matches (necessarily with odds) and by searching through the values ​​of the parameters used, those are found that provide profit in previous matches and, probably, in upcoming ones.

There is a requirement that the sample be of some significance. Well, then it’s just as it comes upcoming match, with calculated parameters, so the program points to it. This type of analysis does not imply winning each match, but only the final profit over a relatively large area of ​​the game.

The benefit of tennis match analysis programs is to minimize the time for analyzing matches and automatically calculate the appropriate odds. In practice, the first and second types of fight forecasting are used, taking into account the type of coverage. Typically, for individual analysis, some basic statistics are still calculated, and when statistical method the recommended rate is subject to intuitive analysis.

A professional sports surface must not only be injury-proof, but also durable, capable of withstanding increased loads during operation. Acrylic coating "" was specially developed for tennis courts for ATP and WTA tournaments, with their high requirements for sports grounds. Lay down " Hard"can be both outdoors and indoors. The main thing is to correctly select the inner layers, which give the court different characteristics for different levels of play (rebound speed and its height).

Advantages of the tennis surface “Hard”

The artificial turf is a multi-layer acrylic cake made from several layers of granular SBR rubber with various additives. Moreover, each of them has its own functional load. Depending on the level and purpose of the court, there can be up to 10 layers in the base, up to 2 in the main part and 1-2 in the final color coating. And each has its own composition and mixing proportions.

Among the features of this sports surface are:

Wide range of operating temperatures from ± 50 ° C, at which it continues to retain its elasticity;
. the ability to lay a different number of softening layers, which allows you to achieve the desired performance in terms of ball rebound and foot shock absorption;
. increased resistance to wear and fading under the influence of UV rays (before the first coating renewal it can be used for about 10 years);
. a wide range of shades to suit any needs and a matte surface that absolutely eliminates the appearance of glare.

The mixture is supplied in liquid form, and the final court surface is formed by pouring it layer by layer. Concrete, regupol, asphalt or wood can be used as a base.

There are many variations of layer combinations. But all of them can be divided into two main ones: “pure” without softening (only 1-2 preparatory layers and 2-3 finishing layers) and “softened”. In the first case, you get a hard and fast court for fans of speed tennis. And in the second, the coating is more comfortable for the feet and less dangerous.

Hard coating technology

The asphalt base for the court must have a finely dispersed structure with minimal porosity. When arranging it from scratch, first lay out the first layer of coarse-grained asphalt of 4-5 cm, and then the second fine-grained one of 3-4 cm. The slope of the resulting plane should be within 0.8-1%. You should not reduce it to zero - this will lead to the appearance of puddles on the court.

The concrete base must be at least 12 cm thick and have a strength of 20 mPa. To remove the cement film, it will be necessary to treat it with 70 percent phosphoric acid. It should not contain hardeners or hardeners. And you will have to lay a reinforcing mesh on wooden and reguole bases.

Before pouring the coating, the surface underneath is cleared of dirt, tar, and oils. It should not have cracks and should be well dried. New asphalt or concrete before application Harda should be kept for one to two weeks until completely hardened.

The technology is quite labor-intensive and requires strict adherence to instructions regarding mixing the composition and its concentration, depending on the porosity of the base, surrounding humidity and temperature. Each layer will take up to one day to dry outdoors and up to three indoors. And most importantly, during all work, no water is allowed to enter the poured layers. If rain is expected, the work must be rescheduled for another time.

Maintenance of tennis courts with hard surface

In closed halls, care is carried out by periodically cleaning the court from dirt and lint tennis balls and traces of sports shoes. First, the area is vacuumed, and then it is wet cleaned using a floor scrubber, the bristle of which should be of medium hardness. It is recommended to use a vacuum cleaner as soon as dirt appears, and to wash the court at least twice a month.

In open-air areas, regular cleaning is done with a blow-out vacuum cleaner or a soft-bristled brush. There should be no foreign objects (branches, leaves, etc.) left on the surface of the court. Plus, it is necessary to perform wet cleaning every month using a mini-wash or the same disc scrubber machine.

It is strictly prohibited to use chemically active products based on alkalis and acids when washing. Do not allow the coating to come into contact with hot objects, and especially with open fire. And so that the court with Hard served for as long as possible, you should use only sports shoes to play and do not allow strangers wearing cleats or shoes with sharp heels to walk on it.

Hard tennis court surfaces are suitable for playing tennis, thanks to its characteristics. While playing on such a surface, tennis players feel confident and comfortable; The matte structure of HARD eliminates glare, and the minimal absorption of the ball's energy and its excellent visibility make the surface ideal for both training and sports competitions;

Properties Hard

The properties of the material for site construction are stable for use over a wide temperature range from -50 to +50 degrees; An almost ideal plane is achieved using a special leveling technology. The HARD structure has several layers applied in a certain way, resulting in a homogeneous surface with excellent performance characteristics, which include color, texture and elasticity;

Depending on the number of softening layers with rubber crumbs and the content of quartz sand in the composition, you can adjust the speed of the ball's rebound.

The construction of tennis courts in Moscow is carried out by Sport-Coating LLC, which has more than 15 years of experience in this field; The price of specialized HARD compounds for tennis courts fully corresponds to its quality, the company’s warranty is 3 years
At the preparatory stage of construction of the site, concrete is first poured, which is covered on top with a special polymer acrylic composition.

Professional composition for use on HARD tennis courts is durable and comes in a variety of colors; HARD - the coating is one of the most convenient for playing tennis; its surface is quite hard and consists of several layers of special polymers, which allows you to clearly control the rebound of the ball and keep the game under control.

The hard drive has quality guarantees and a long service life. In addition, Hard is used in professional ITF competitions.
* The company "Sport-Coating" LLC has been laying and supplying material for tennis courts for more than 15 years. Our experienced experts will provide professional advice and arrange a reliable surface for sports ground in a short time at the best price.

When choosing a tennis surface, it is important to determine the correct number of softening layers and a certain level of hardness. The most universal option is Hard on a rubber roll backing (Regupol/Kraiburg). It hosts championships and the surface is certified by the ITF (International Tennis Association).

HARD sports surface, varieties and structure

HARD is the most practical and unpretentious material to use. It consists of several layers, usually from 5 to 14, which are acrylic polymers of varying degrees of rigidity.
The coating of HARD tennis courts contains functional layers, softening and finishing (marking).
Functional layers serve to shape its properties, softening properties are important for the ball's rebound and for the players' joints.
Often, when constructing sites, a special rubber backing is used as the first layer, which is an excellent shock absorber, making use more comfortable and safe; in addition, the rubber underlay for self-leveling layers HARD helps ensure the evenness of the surface if the base is not too level.
The price of HARD coating depends on the number of layers and the presence of a softening substrate. By purchasing material from us, you receive guaranteed high quality and coatings tested by professional players.

The rubber backing is attached to the base of the platform and provides additional softening, allowing you to maintain the structure of the material for a long time, due to its unique shock-absorbing properties.
Professional sports surface HARD is used during competitions, training of professional tennis players, and is suitable for amateur courts. Can be used for other sports. In case of using a multisport platform, the use of additional softening or rubber backing is recommended.
A shock-absorbing backing made from recycled crumb rubber is attached to the base with heavy-duty adhesive and provides additional softening, allowing the structure to be maintained for a long time due to its unique shock-absorbing properties;

The material is laid in several stages: First, you need to prepare the base. For a sports surface, the evenness of the base is extremely important: It should be free of cracks, potholes, etc., in some cases a leveling screed is sufficient, but it is much better if the concrete or asphalt base is initially laid out in a completely even layer.
This is due to the fact that the material has a structure that, like a self-leveling floor, completely replicates the surface of the site.
* With a properly prepared base, the future court will be suitable for use for as long as possible, more than 15 years, and no puddles will form on it. Therefore, the preparatory stage when constructing a tennis court is extremely important: compliance with technology, building codes, creating a slope of the site along the entire plane, thermal seams.
The structure of the Hard sports surface is such that in case of minor damage, it will be enough to locally repair the surface by filling it with a small amount of polymer.
When choosing a sports surface, it is recommended to take into account the future intended use: if the players are experienced, preferring quick game, then the HARD material is chosen to be sufficiently rigid, with the fastest possible rebound of the ball.
We recommend using a 4-6 mm rubber backing or additional softening, this will make the game more comfortable and injury-free. This becomes especially relevant if children play tennis.
Additional softening layers are added to the composition; there can be up to 8 of them, but the minimum softening that it is advisable to add to all areas is 2 layers.

Use of rubber backing in the construction of tennis courts

The average service life is 15 years, and in case of minor damage, it is enough to locally repair problem areas, update the top and marking layers, and the site will be like new again, with minimal costs.
Unlike the all-purpose rubber surfaces on a tennis court, HARD allows for more dynamic play. Experienced tennis players know how important accurate ball bounce and a flat blade are to placing shots accurately and being able to play on the edges of the lines.
Majority professional competitions take place on Hard, this material has long earned special love among tennis players.
Dimensions of a standard tennis court
23.77m x 10.97m - area for doubles play,
23.77m x 8.23m - area for single player.
Total area 648 m2 (with runs)

The first mentions of hard surfaces known to us date back to the early seventies of the last century. It was in the USA that the surface was widely used at that time, and since 1978 one of the main tournaments has been held on the hard surface (Deco Turf surface manufactured by California Products Corp.) Grand Slam US Open. Grass courts of the first of the four Grand Slam tournaments of the season Australian Open also long ago they gave way to hard courts (Plexipave coating).

CONQUEST OF RUSSIA

In our country, the first hard courts appeared in Moscow already in 1979 - at the Chaika tennis club on Prechistenskaya Embankment, next to the Park Kultury metro station, and in Luzhniki. At this time, in preparation for Olympic Games in Moscow in 1980, new foreign sports materials and technology. From this time on, "Chaika" long years becomes one of the most fashionable and popular places in Moscow at that time. Indoor courts (the structure had a retractable roof, which made it possible to open the courts in the summer) with a modern hard surface in the center of Moscow attracted many tennis fans from among well-known politicians, officials and cultural figures.

When constructing the above-mentioned courts, Soviet sports surface layers from Soyuzsportstroy, together with American specialists, laid a hard surface for the first time. It should be noted that acrylic coatings were very different from the chemically aggressive epoxy and polyurethane sports coatings that were common at that time. The absence of pungent odors, the ease of preparing materials for application, the ability to clean work clothes and tools with ordinary water caused a pleasant surprise among our craftsmen.

TWO MAIN VARIETIES: “PURE HARD” AND “SOFTEN HARD”

In recent years, an increasing number of companies in our country have been offering their services for the construction of tennis courts with hard surfaces. The general name “hard” refers to a whole range of coatings that have significant differences.

There are two main types of “hard” coatings: “pure hard” (coating without special substrates or softening layers) and “softened hard” (coating on a rubber backing or using special layers containing rubber granules of different fractions). “Pure Hard” is a system of acrylic layers consisting of preparatory layers (using Filler Coat Binder or Acrylic Resurfacer), textured color layers with a special quartz filler and finishing color layers. Such coatings are widely used on outdoor tennis courts and are inexpensive.

“Softened hard” differs from “pure” in that it contains layers of softening (3 layers with large rubber granules and 2 layers with small rubber granules), a total of at least 5 layers.

Another option for “softened hard” is when the acrylic system is applied to a rubber backing glued to the base (there are configurations on a polyurethane backing).

The advantage of “soft hard” is that this surface is more comfortable for the player, and therefore suitable for ordinary tennis fans.

Hard coating configurations may vary slightly and depend on the specific manufacturer.

ATTENTION - ON THE BASIS!

When constructing a hard tennis court Special attention should be turned to the base. For outdoor courts, as a rule, an asphalt concrete base is chosen. Indoor courts have a concrete or asphalt concrete base.

The requirements for the base surface are very high, the thickness of the tennis coating is from 1.2-5 mm. The service life of the coating is quite long and all the troubles are connected precisely with problems in the base.

BETTER THAN THE ORIGINAL - ONLY THE ORIGINAL!

Today there are a large number of different hard-type coatings on the market, including domestic ones. However, it is important to understand that “hard” will serve properly for many years only if acrylic and special additives with guaranteed quality are used. Therefore, in most cases, preference is given to American coatings. For more than 40 years, manufacturers have been improving the composition of hard tennis surfaces. A high-quality hard surface does not fade in the sun, does not glare in natural or artificial light, and does not lose its sporting characteristics for more than ten years. Small savings when choosing hard coating can reduce all its advantages to “no”.

Today, anyone can go online and find more than a dozen companies offering modern acrylic coating. You need to be very careful in choosing. Unfortunately, in fact, not everyone offers high-quality coverage and deliberately misleads the buyer by showing beautiful samples of “hard”. Moreover, the websites of many companies are full of advertisements that they are official and almost the only partners of large foreign brands (although it is not very clear how one can be a partner of a brand; it would be correct to indicate the manufacturers). In any case, in well-known Western companies producing sports surfaces They don’t even suspect how many “official” and “only” partners they have in Russia.

Imported hard coatings are supplied in original packaging of 55 gallons (metal drums) or 30 gallons (plastic drums). 5 gallon packaging (plastic buckets) is very rare. Coating in the form of a concentrate. The concentrate is diluted with water and in some cases special quartz sand is added. All actions are performed according to the recipe strictly defined by the manufacturer. After which the material, ready for use, is applied to the surface of the base layer by layer manually using a special rubber rake. Each applied layer dries completely in about a day.

Material that is diluted with water greatly tempts our domestic layers, which is why such an indicator as the number of layers of hard coating fades into the background. When concluding a contract for a hard coating device, in addition to a clearly defined configuration, it is necessary to include a specification with a full description of the materials used and their quantity in the original packaging. And don’t be shy about asking the contractor for certificates and documents about the origin of materials.

So, if you choose a real hard surface and professionals in laying acrylic surfaces, you will get a modern tennis court that does not require any special maintenance for more than 10 years with the highest sporting characteristics. Among other things, professionals will guarantee the work performed for at least 3 years and the materials used for at least 7 years.
