Underground floor. Consumption per 1 m2 of bulk floor: practical calculations

The modern market of finishing and building materials provides a wide range of different floor coverings. Due to the variety of materials and their properties, it is possible to carry out any design projects. One of the most popular types of coatings is a bulk floor, the device of which is carried out by dry gypsum cement or cement mixtures.

These are plastic quick-setting materials. Due to a special structure under the influence of their own weight, they spread, fill irregularities in the bases, forming an ideal plane.

The advantages of self-leveling floors

The coating, which is defined as a bulk floor, has several advantages:

• Smooth and flat surface;
• Rapid setting;
• Strength and durability;
• Resistance to temperature changes;
• Ease of maintenance.

Types of coating

The floor is a self-leveling mixture that spreads very easily throughout the entire area of the room, thereby forming a smooth and even surface. These coatings are divided into two types: polymer and mineral.

Polymer self-leveling mixtures are divided into several types.

1. Polyurethane . Elastic coatings, resistant to impact, withstand heavy loads and are used in unheated rooms.
2. Methyl methacrylate . Such floors require strict compliance with the technology when stacking, are resistant to mechanical stress, have a sharp odor. They are used in well ventilated areas.
3. Epoxy-urethane. The floors of this kind have elasticity, resistance to abrasion, chemical agents. Used in garages, on ramps.
4. Epoxy . This is a hard, hard, shock-resistant coating. Withstands high temperature and mechanical stress, easy to clean. Such floors are poured in closed rooms.

Mineral coatings are self-leveling mixtures based on cement with modifiers and mineral fillers. Use this solution when applying the finish coat.

Methods of classification

Polymer floors are classified according to the following factors:

• Degree of fullness;
• Type of solvent;
• thickness.

In terms of thickness, bulk floors are divided into types as follows:

1. Thin-coat coatings. Their thickness is 0.2-0.6 mm. Do not withstand a very large load. Fit with roller or spray.
2. Medium thickness. The applied layer can be 0.8-1.5 mm. Such self-leveling coatings withstand average load.
3. Highly filled coatings. Their thickness is 2 mm and more. Appearance depends on the characteristics of the filler. Used in decorative and specialized purposes.

Depending on the degree of filling, the material is characterized as follows: the more filler, the more rough the surface will be.

The solvent happens:

• Water-dispersion - the coating is odorless, it can be applied to wet concrete, since its base is water.
• Resin without a solvent - the floor differs from others in low viscosity, sometimes has a faint smell, is convenient in laying.

Material consumption per 1m ²

To eliminate the defects of the floor bases, to improve the sound or thermal insulation, it is necessary to carry out a whole range of works on pouring screeds or self-leveling floors. To do this, you need to find out how much the finished mixture will take, without taking into account the impurities. If you make a bulk floor, the consumption per 1 m2 on average will be 1 liter. This value differs depending on the manufacturer. To obtain more accurate calculations, it is necessary to multiply the area of the coating by the density of the material and the thickness of the layer. Consider several popular mixtures and their calculations.

For the lay-out and adjustment of brick, concrete and stone floors, a cement-sand screed that fits over the base is suitable. The solution is used in all types of premises, as a waterproofing protective layer. It can not be affected by natural oils, water, solvents, alkalis. The flow rate of the filling floor per 1 m2 of the screed is 2 kg with a layer thickness of 1 mm.

Fast hardening floor "Starateli" is used to smooth unevenness from 0.5 to 8 cm. This coating has a set of protective properties against premature wear and exposure to aggressive substances. A high-quality filling can withstand loads of over 70 kg. It does not have microcracks. The floor (consumption per 1 m2) "Starateli" with a coating of 1 cm layer will require 16 kg of dry material. To prepare the solution, you need 5-6 liters of water per 25 kg of the mixture. The production time is 40 minutes.

The "Found" mixture for the device floors is applied manually or mechanized. It is used in office, industrial, residential premises. The flow rate of the filling floor per 1 m2 "Found" with a layer thickness of 0.3 cm is 4.5 kg.

The coating "Yunis" allows you to create a smooth and durable surface. It is used for leveling concrete bases and screeds, when there is a significant deviation from the norm (up to 10 cm). The prepared mass quickly freezes, so it is necessary to use it for 30 minutes, otherwise it will lose its properties. The flow rate of the flooring floor per 1 m2 "Yunis" with a thin layer filling up to 1 mm thick will be 1.3 kg and 3.9 kg with a coating thickness of 3 mm.

When using the mixture "Volma" the surface is perfectly flat. Due to its consistency, the mixture easily spreads and evenly fills all irregularities. The flow rate of the floor for 1 m2 "Volma" when pouring a layer 0.5-0.7 cm thick equals 4 kg.

Preparation of the surface for laying the filling floor

Before you start to work, you need to prepare the surface: clean it of different spots and grease grinder, and then remove the garbage with a vacuum cleaner. After that the floor is treated with a primer, it is well dried. Concrete covering or screed can have cracks, so they are glued with fiberglass and covered with quartz sand. Seams on a concrete foundation are filled with a sealant. In a day, excess sand is removed from the cracks. The surface is primed with a polymer compound to improve adhesion. The quality of the floor depends on the rough surface, and if the substrate was properly prepared, under the floor, the consumption per 1 m2 of the primer will be 250 grams.

Designing a floor

After a day after priming, a base layer can be applied to the concrete surface. But first you need to calculate how thick the floor will be. The consumption per 1 m2 of necessary materials and mixture is calculated taking into account the floor differences and all its irregularities. To establish the volume of the room, the laser level determines the horizon of the base, then from different points the differences are calculated.

The relative height is calculated - the size difference is divided by 2. The minimum thickness of the coating is calculated by folding the relative and minimum allowable height.

Filling of the filling floor

Before laying the floor, the walls are covered with a film. To prevent the mixture from flowing under the panels, the entire base around the perimeter of the room is sealed with a mounting tape. On the base prepared for pouring, you should go into the replacement shoes. On the flooded floor, it is recommended to walk in paintballs, with which you can go to separate areas, leveling the surface and leaving no traces.

The pouring of the warm floor starts at the highest point. The poured mixture is spread with a spatula and squeegee. If bubbles form, they are removed with a needle roller. In the room when laying the floor there should be no moisture and drafts. Throughout the drying of the coating, all work is carried out at a temperature above 10 ° C.

When choosing a bulk floor, you can significantly reduce costs. Before installation, lay a layer of pure quartz sand. After the surface dries well (after 5-10 days), it is possible to apply a finishing floor. The consumption per 1 m2 is 0.5 kg of the mixture with a layer thickness of 0.1 cm.

Care of the floor

After the floor has dried, a protective film is applied to the surface. It protects it from damage and is replaced every six months. It is recommended to rub the filler floor with mastic every three months. For cleaning the premises with such a floor covering use: vacuum cleaner, brush, warm water and mild detergent. The floor has one drawback - it is very afraid of heavy and sharp objects.
