Polyurethane coating is widely used today for both private dwellings and public areas. It is good because it is resistant to high humidity, is not afraid of germs and can serve for years. Self-leveling polyurethane floors can be easily laid by hand.

Coating Advantages

Long-term observations have proven that the bulk polyurethane coating is optimal for laying in industrial premises and beyond. They are comfortable and reliable. These floors are a seamless construction with a polyurethane layer, through which the concrete part of the coating is closed.

They are highly resistant to both mechanical and chemical influences, are elastic, and can withstand temperature changes.

Key characteristics of polyurethane coating:

  • dust-free;
  • sustainability;
  • easy installation;
  • wide range of textures;
  • practicalityapplications;
  • service life up to 20 years;
  • sustainable;
  • easy care.

Uses

Such a polyurethane coating is recommended to be laid in rooms where there is frequent vibration and movement of the floor, as well as where there are hard abrasive loads.

They are often used on objects such as:

  • repositories for various purposes;
  • freezers and refrigerators of industrial type;
  • food production;
  • office space;
  • exhibition centers and terminals;
  • warehouses and hangars;
  • non-food production workshops;
  • agricultural facilities.

Specifications

Polyurethane flooring is one of the varieties of polymer compositions. At the same time, against the background of all the others, it is the most elastic and has minimal sensitivity to cracking of concrete, which goes in a layer below it: cracks overlap up to a millimeter. Also, due to its characteristics, it has a high impact resistance compared to other self-leveling coatings. For example, a polyurethane floor is able to withstand even a drop of a load from a meter height weighing up to 5 kg. And frost-resistant characteristics allow it to be installed in industrial refrigerators.

In addition, it is great for outdoor areas and rooms where there is no heating. For example, sports grounds can also be madebased on polyurethane.

Classification of structures

Floors of this type are of the following types:

  • thin-layer;
  • universal;
  • decorative;
  • anti-slip;
  • anti-static.

Let's take a look at how each listed polyurethane coating differs from the other.

Thin-layer and universal floors

These types of coatings are a composition of resins based on polyurethane and are used for closed objects where there will be no mechanical stress or strong friction. They are distinguished by their attractive appearance, ease of maintenance, resistance to dirt and a solid base. You can update such a polyurethane coating by simply repainting it.

Install it on a concrete base, which bears the main load. And the coating itself has a thickness of up to 0.5 mm. It is made by sanding and filling the base, then applying up to 2 coats of primer and varnish.

But universal coatings are used for multilayer floors without seams. They are used in enclosed spaces such as workshops, workshops, warehouses, manufacturing, hospitals, shops and more.

They are highly durable, abrasion resistant and dynamic load resistant, non-slip, easy to care for, and they tolerate cleaning chemicals well.

The thickness of such a coating depends on its functions and base and ranges from 1.5 to 2.5 mm. It can be much larger ifthe base is uneven and needs to be leveled.

Decorative and other types of floors

The price of polyurethane coating depends on the manufacturer and its characteristics. Decorative floors can cost differently depending on the thickness, colors and other features. They consist of a base material, decorative PVC parts and a lacquer finish.

And anti-slip coatings are used for the manufacture of multi-layer self-leveling structures. They are relevant for enclosed spaces of industrial and industrial type. They consist of polyurethane coatings with an anti-slip effect of a polymer mass, which includes a quartz filler.

Anti-static products are designed for closed industrial premises, where it is highly undesirable to accumulate static charges. This includes rooms with a large number of computers and other equipment, as well as those containing explosive substances. They are capable of dissipating static charges, have an attractive appearance, and do not accumulate dust.

Coatings for sports fields

Some types of floors can be used in fitness centers, training facilities for football players and other facilities of this type. Such coating for sports grounds not only looks attractive, but also differs in traumatic safety and high quality.

Depending on the requirements, it can have a different structure: porous, rough or monolithic. The coating for sports grounds is being poured on a base made of concrete or with the addition of asph alt, or on the old one that was used at the facility before the repair.

The main advantage of this type of flooring is not only the affordable price. Thanks to their installation, the sports field, fitness center or production hall will become safer. After all, they are united, first of all, by the fact that visitors to such facilities may receive certain injuries due to classes or work, but the main thing is to prevent this.

Installation work

Filling is carried out by means of a squeegee, roller and drill with a nozzle in the form of a mixer. Also do not forget about the primer to prepare the base for the coating. Some compounds are absorbed too quickly, so in some cases the procedure is performed twice in a row.

Filling work should be done when the room temperature is 10-25 degrees with a humidity of 75 percent. Until completely solidified, exclude the possibility of drafts and temperature changes.

Mix the contents of the bucket so that there are no seals or lumps. Let it brew for 15 minutes and repeat the action. Don't mix too much of the mixture at once, as it sets within an hour.

Filling begins 12 hours after priming. Start from the far corners and then move to the exits. The floor will harden on about the second day, until then you can’t walk on it.

As for the cost of polyurethane coatings, it ranges from 300 rubles perkilogram. Bulk floors are sold most often in buckets weighing about 20-25 kilograms. A square meter of coverage will cost from 157 to 900 rubles per square meter. Before purchasing this or that composition, decide where exactly this coating is planned to be laid. Indeed, in composition, they can differ significantly from each other, and what is suitable for one object will be categorically unacceptable in the conditions of another.
