Crumb rubber is great stuffwhich has a wide scope of application. Due to the mass of positive qualities, its use when laying coatings is very effective. They are particularly relevant in sports and playgrounds, as well as in industry. There is a bulk, tiled and rolled coating of crumb rubber.
Rubber cover
Резиновая крошка – это совокупность гранул various shapes, made from crushed and recycled automotive rubber, preserving the molecular structure and properties of the original material.
For a high quality coating to itIt is necessary to add a binder, which consists of polyurethane. It gives the material elasticity and allows for strong adhesion to the base. When used, the crumb rubber coating is reliable, elastic and durable.
The material is produced in rolls or tiles.Coloring is carried out by adding different dyes. Crumb coatings have an uneven surface that eliminates the possibility of slipping. You can use them in any weather conditions, since no dirt or water collects on the surface.
Scope of application
The antiskid, safety, wearproof covering from a rubber crumb is widely used for a construction:
- gyms, stadiums, tennis courts;
- playgrounds;
- livestock buildings.
This material is also used in variousareas of industry. Rubber crumb is used in the oil industry in the manufacture of mixtures intended for the operation of wells. Apply it in the production of sports equipment, rubber products.
Widespread seamlessrubber crumb coatings in civil and road construction. When you add it to the asphalt get high-quality material for sidewalks, roads. It is used for the manufacture of products of various coatings: pavers, carpets, tiles, self-leveling floors.
Benefits
The coating, which includes an element such as crumb rubber, has the following advantages:
- Sustainability. The material is resistant to temperature extremes, bends and tears, ultraviolet rays.
- Wear resistance. Products from this material have a long service life.
- Aesthetics.Due to the wide color palette and its combination, it has a beautiful, attractive appearance. It is resistant to fading and exposure to aggressive environment (alkalis, acids, solvents).
- Hygiene On the coating does not appear rot, mold, weeds, insects.
- Elasticity and safety. The material from rubber crumb does not emit toxic substances and is harmless to health. It has traumatic and shock-proof, as well as anti-slip properties.
- Easy to care. The coating does not shrink, grass does not germinate through it. It is easy to clean, and is vacuum cleaned indoors. Does not create problems when replacing the damaged area.
Stages of installation
In the article we will give an example of how to laycrumb rubber coating designed for the sports field. It should be noted that it can be used both indoors and outdoors.
In order to get quality coverage,should strictly comply with the technology of its installation. At the beginning of the process, it will be necessary to prepare the surface and perform priming. Then the coating itself and the monolithic layer are laid. And at the end of the work markup and finishing varnish is applied.
Surface preparation and primer
Спортивное покрытие из резиновой крошки обычно applied on a wooden, concrete or asphalt base. For good grip, the surface must be cleaned of dirt. If the foundation is concrete, it is moistened with water, polished, then the dust is removed with a vacuum cleaner. Work on the street is carried out at air temperatures above +5 degrees. In the end, after the end of the first stage, the surface should be clean, dry, slightly rough.
Следующий вид работ – грунтование, которое должно ensure good adhesion, impregnate, dust, harden the surface. To do this, use the primer ADV-46, ADV-56, ADV-17. Each of them has its own characteristics and purpose. Select should be based on the conditions of applying a layer of primer. After the end of this stage, you need to proceed to the next, the break should be no more than a day.
Laying the coating and the monolithic layer
Covering rubber crumb do it yourselfnot difficult to perform. If work is being done in the open air, it is necessary to ensure that during the day there will be no precipitation expected. Preparing a special mixture. The following calculations are intended for a layer thickness of 0.1 cm at a site of 1 m2. It will take:7 kg of crumb rubber, 1.5 kg of ADV-65 binder, 0.3 kg of pigment. All components are mixed in a concrete mixer. The received weight is applied on the basis covered with a primer. The platform is leveled with squeegees. Then roll it with a greased anti-adhesive roller.
If the coating is placed indoors,will require the application of a monolithic layer. It provides resistance to mechanical stress. First, the pad is covered with ADV-61 putty to close the pores. The reinforcing layer of the grid rests on it. After 24 hours, compound ADV-61 is poured. Thickness is 1,5-2,5 mm. Leveling is done with a squeegee and notched trowel.
When performing work, the optimum air temperature is +20 degrees, humidity 80%. Site operation is possible one week after laying the coating.
The final stage
When the main work is done, on sportsrubber crumb coating should be applied markup. It must be dry and clean. The air temperature during dyeing - from +5 degrees. The markup is performed with a mixture of such components: oligomer ADV-17, coloring paste, catalyst. Drawing is carried out by roller or brush. Consumption per 1 m2 - 200 grams of the mixture. Coloring should be done in two layers.
To make the rubber coating more resistant towear and had a beautiful appearance, 24 hours after laying it is covered with lacquer ADV-63E. Drawing is carried out by the velors roller in two layers. Consumption per 1 m2 - 0.05 kg of varnish. The break between the layers is 3-6 hours.
Feel free to lay the rubber crumb coating on the sports fields. This is a great option for use in these purposes, and not only.
