Rubber cover

If we consider the structure of rubber crumb, then its basis form granules of different shapes, the raw material for which is powdered and recycled automotive rubber, having the same molecular structure, which is characteristic of the source material.

To make a high-quality coating, a binder comprising polyurethane is introduced into its composition. Thanks to him, the material is able to demonstrate high elasticity and is able to firmly hold on the base. The use of this material allows you to create reliable, resilient and durable rubber crumb coatings.

This material is available in rolls or tiles. A variety of rubber crumb and in terms of colors, due to the presence in the composition of the corresponding dyes. Coatings created with this material are characterized by the presence of an uneven surface, which makes them resistant to sliding. Such a coating can be used in all weather conditions, since on the surface dirt and water do not accumulate.

Scope of application

Rubber crumb coating is demanded due to such qualities as anti-slip, injury-resistance, durability, which caused its distribution during construction:

• gyms, stadiums, tennis courts;
• playgrounds;
• livestock facilities.

In addition, the material under consideration has been distributed in many areas of industry. Rubber crumb is in demand raw materials for oil productionwhere it is based on the mixture used in the operation of wells. It is also present among the components used for the manufacture of sports equipment, as well as various rubber products.

Rubber crumb coating is distinguished by the absence of seams, which led to its wide distribution in civil and road construction. This material is a component present in the composition of asphalt, so that it is possible to create high-quality coating for sidewalks and roads. In addition, on its basis, make other types of coatings: paving, carpets, tiles, self-leveling floors.

Benefits

The use of crumb rubber provides a coating based on it. following advantages:

• Persistence Such material tolerates temperature fluctuations, as well as any types of deformation and exposure to ultraviolet light.
• Wear resistance. Due to the special properties of this material is durable.
• Aesthetics. A wide variety of color solutions and their combinations allows the material and coatings to look quite attractive. This is largely due to the ability to resist burnout and the effects of aggressive substances, including alkalis, acids and solvents.
• Hygiene Created on the basis of rubber crumb coating demonstrates resistance to the appearance of rot, mold, weeds and insects.
• Elasticity and safety. The absence of toxic secretions in this material makes it safe for humans. This is largely due to the presence of such properties as tram and shock resistance, as well as anti-slip.
• Easy to care. Due to the lack of shrinkage and the presence of a seamless structure that does not allow the grass to grow through the cover, it does not require special measures to maintain it in proper condition. Coatings that are on the street are quite easy to wash, and those that are located on the premises can be kept clean with a vacuum cleaner. They are also maintainable.

Stages of installation

The question of how to lay a crumb rubber coating is relevant to many who plan device playground. It will be useful to know to everyone who is going to use this material indoors or outdoors.

It is possible to create a high-quality coating only on condition that the requirements of the installation technology are exactly met.

• At the first stage, the surface is prepared, after which a layer of primer is applied.
• After that, they proceed to the laying of the coating, followed by a monolithic layer.
• The final step is the application of the markup and finishing varnish layer.

Surface preparation and primer

When creating a coating on the basis of crumb rubber with their own hands, most often it acts as a base. wooden, concrete or asphalt surface. In order to improve the adhesion properties, the dirt should be removed from the base on which the installation will be performed. If you have to deal with a concrete surface, it must first be moistened, then polished, and then cleaned of dust using a vacuum cleaner. When conducting training on the street, it is important that the temperature regime is in the range of + 5 degrees Celsius. If the surface preparation was performed correctly, the base should be clean, dry and slightly rough.

Then go directly to the priming, the main positive point of which is to improve the adhesion. In addition, this operation effectively removes dust and gives the surface increased strength characteristics. The material used grafting ADV-46, ADV-56, ADV-17. To approach her choice should be properly, because they all have their own characteristics and purpose.

In order not to be mistaken with the choice, you need to focus on the conditions in which the priming will be carried out. When all the basic operations of the first stage are completed, it is necessary to pause for one day at most, after which you can proceed to the next stage.

Laying the coating of the monolithic layer

To create a covering from a rubber crumb on forces even to the nonspecialist. If work is planned on the street, then you need to make sure that this day will be sunny and without bad weather. First you need to prepare the working mixture. In order to correctly calculate its quantity, it is necessary to adhere to the following scheme, which corresponds to the norm for a layer thickness of 0.1 cm when processing a 1 m area².

For it is necessary to take:

• Rubber crumb - 7 kg,
• Binder ADV-65 - 1.5 kg.
• Pigment - 0.3 kg.

The listed components are placed in a concrete mixer and thoroughly mixed. When the mass acquires a homogeneous structure, it covers the base, which has already been applied primer. To give the area a flat surface use squeegees. After that, you need to walk on it with a roller, which is pre-applied release agent.

Its features are in terms of creating a cover with your own hands indoors. In this case, the technology provides monolithic coating. Thanks to him, the surface will acquire increased resistance to mechanical stress.

The first step is applying the ADV-61 putty, which will eliminate pores. Next to her place the reinforcing layer mesh. After a pause of 24 hours, they begin to pour compound ADVB-61. The layer should turn out in the thickness of 1.5-2.5 mm. To level the created surface, use squeegees and a notched trowel.

To avoid unexpected results, you should make sure that optimum conditions are created for the work: air temperature + 20 degrees, humidity - 80%. The site will be ready for use only after a week has passed since the laying of the coating.

Final stage

Having completed the main work, proceed to the next stage in the creation of a coating of rubber crumb - marking. To do this, make sure that the surface is clean and dry. Care should be taken to create the optimum temperature for dyeing, which should not be below +5 degrees. To create the markup, a mixture is used, which prepared from the following components:

• oligomer ADB-17;
• coloring paste;
• catalyst.

A roller or a brush is used as a marking tool. Usually to create markup on the area of ​​1 m² 200 g of mixture leaves. To perform high-quality staining can only be provided that this work will be carried out in two layers.

It is also important to take measures to increase the ability of the coating to resist external influences. Therefore, after a day has passed since it is laid, ADV-63E lacquer is applied to it, which, among other things, will give the coating a more aesthetic look. The technology of coloring involves applying the mixture in 2 layers using a velor roller. At 1 m² surface leaves 0.05 kg of lacquer. Between the layers it is necessary to sustain a pause of 3 to 6 hours.

Such material is perfect for creating coatings on sports fields. At observance of all requirements of technology it is possible to guarantee that the covering will successfully cope with the task.

Conclusion

Rubber crumb stands out against the background of other similar materials with its unique properties, which made it a popular material, using which various coatings are created. First of all, it is used at such facilities as stadiums, gyms and playgrounds, where high requirements are imposed on the base in terms of wear resistance. Laying rubber crumb coating is a fairly simple exercise. If you strictly follow the rules of applying the coating yourself, then you can, without even having the experience and skills to work with this material, to achieve a quality result.
