Self-leveling floors have appeared relatively recently. From year to year they are becoming more and more popular. There is nothing to be surprised at. The starting material for pouring exceptionally flat surfaces is available in every decent building store. Instructions for use are printed on the packaging. The arrangement technology is so simple that anyone can master it, and the result is always excellent.

The appearance of self-leveling floors is pleasant and elegant.

Features of the

Self-leveling floors, depending on the composition, are divided into several types:

  • cement-polyurethane;
  • methyl methacrylate;
  • epoxy;
  • epoxy-urethane;
  • polyurethane.

Methyl methacrylate, unlike others, can be poured at an air temperature of + 8 degrees. The main advantage is increased frost resistance. Installation of such a floor requires professionalism, since the hardening occurs very quickly, and the process itself is accompanied by the release of an unpleasant odor.

Methyl methacrylate floors are appropriate in unheated industrial premises.

Floors epoxy withstand physical influences, resistant to moisture, oils, harsh chemicals. Installed in chemical laboratories, at pharmaceutical enterprises.

Polyurethanes are most in demand, since they have a lot of positive qualities. Among them:

  • long service life;
  • excellent view;
  • indifference to sudden changes in temperature.

Due to its resistance to oils, alkalis and other aggressive chemicals polyurethane floors began to appear frequently in industries with increased demands on hygiene. They can be seen at enterprises processing agricultural products, at meat processing plants, in bakeries, in industrial freezers and other similar premises.

Recently, polyurethane-based floors have also been used in residential construction.

What affects the quantity?

Self-leveling floor is expensive. A thrifty owner will not want to spend too much, and will definitely find out what can affect the consumption of the mixture.

There are several factors affecting the amount of material required.

The most obvious are: the area to be treated and the thickness of the floor. The rest are not so obvious, but no less significant.

Image
Image
Image
Image

Suppose that the subfloor, on which it is planned to apply the self-leveling, is in good condition, then 1 sq. m will go less mixture than with the same thickness, but with a poor-quality base.

The fact is that each crack absorbs the precious liquid of the self-leveling floor. The plastic mixture, poured over the rough floor, fills each of its flaws, is absorbed into the pores, and penetrates into cracks and potholes. Conclusion: consumption depends on the quality of the base.

The purpose of the floor matters. If he just needs to level the surface for the subsequent flooring, the thickness can reach several centimeters, and the consumption can be decent. With a thickness of several millimeters, the self-leveling coating in the apartment is the finish. In this case, the consumption is significantly reduced.

To determine the consumption, you need to focus on the shelf life of the material, as well as on its density. If we take into account the average density indicator, then it is as follows for different species:

  • 1.25 - 1.35 kg / l for polyurethane compounds;
  • 1.4 - 1.65 kg / l for epoxy;
  • 1.6 kg / l for acrylic-cement mortars.

Failure to comply with the technology for performing work can lead to overruns of the composition. Therefore, you should follow the instructions on the packaging for each type of self-leveling floor.

Calculation of the norm

In order to calculate the need for a self-leveling floor, you need to take the initial value. The starting point for any mixture is taken as a uniform one. It consists in the fact that to obtain a layer in a height of 1 mm per 1 square meter, 1 liter of the composition is required … Fillers are not included in this case.

Further calculation assumes an adjustment taking into account the density of the material used. For example, if the density is minimal and equal to 1.2 kg / l, then for the same square meter with a layer height of 1 millimeter, there will be not 1, but 1.2 liters of the mixture.

Image

Image
Image

Finding out the density of the material is not difficult. Manufacturers always indicate it on the product packaging. Knowing the density data, it will not be difficult to calculate the flow rate for a specific case.

For example, let's take a room with an area of 20 m2. Let's say that the filling should be 2 cm thick, and the self-leveling floor is chosen on an epoxy basis. Density, according to the manufacturer's data, 1.5 kg / liter.

Image
Image
Image
Image

Multiplying the values of the density of the material, the area of the room and the thickness of the fill, we get the need for the material in kilograms.

1.5 x 20 x 20 = 600 (kg)

Considering that the dry mix is sold in 25 kg bags, you can find out the number of bags:

600 kg: 25 kg = 24 bags

Less material will be required for the finishing self-leveling floor, since in this case the thickness is much less - from 3 to 5 mm. However, more than the calculated value may go to the cement base without its pretreatment, since the cement will absorb part of the liquid substance.

How to reduce consumption?

A negative factor is the high cost of self-leveling floors. Fortunately, there are ways to significantly reduce costs. You just need to carefully study them, and then use the knowledge gained.

An unproductive consumption of valuable material can occur when pouring on an unprepared base. Losses can be 20% or more. In order to prevent losses, you need to take all the responsibility to the arrangement of the base.

The old floor is subject to careful inspection. All identified flaws must be eliminated: potholes, sinks, chips must be sealed with mortar, small cracks must be putty.

If there are stains of paint, oil or other liquids on the subfloor, a solvent is used. There should be no stains, dirt or dust on the substrate.

The cleaned surface is primed. This operation is performed after the solution and putty have completely solidified. If necessary, apply the primer in two layers.

If the base is badly damaged, do not waste time on local repairs. The best solution would be to equip a full-fledged screed. Before pouring a self-leveling floor, a new screed is also primed without fail.

Image
Image

Instead of a cement screed with insignificant differences in height, a leveler can be used to level the surface under the self-leveling floor.

Professionals working with self-leveling floors make bedding when working with polymer coatings. After pouring the base, quartz sand is poured onto its not yet solidified surface. When the base sets, the excess sand is removed. This simple trick significantly reduces the consumption of the mixture.

On the prepared basis, using a laser level, they mark the horizon, determine the height differences, then calculate the volume to be filled. The required number of bags of dry mix is found by volume. The more accurately the measurements and calculations are made, the fewer mistakes the builder will make, and the more finance will remain for other related work.

When performing calculations, you need to remember about the possibilities of various types of self-leveling floors. So, for epoxy, the maximum possible layer thickness is 6 mm, and for polyurethane only 3 mm.

The thinner the self-leveling floor layer, the less material consumption. A thin layer can be obtained from quality mixtures of trusted manufacturers. Despite the fact that the liquid mixture levels out on its own, it will not be superfluous to mark the final horizon with beacons. Self-tapping screws are used for point landmarks.

And the last thing that will not allow the overrun of the mixture is strict adherence to the rules for pouring it.

Composition of mixtures

The best liquid floors are made from self-contained mixtures. They already contain everything you need to get a flawless finish. It remains to stir the dry contents in water to the desired consistency and pour onto the base.

Due to the high cost, the preference is often given to cheaper combined formulations. In such mixtures, a significant proportion is assigned to cement. It does not act as an ordinary filler, but is a full-fledged component with its own unique task. In this case, the cement takes care of imparting viscosity to the mixture.

The second part includes several elements at once. These are mineral additives, polymer fillers, and modifiers. This also includes fractional sand. The listed ingredients provide the mixture with the ability to spread smoothly, harden quickly, forming a solid monolith.

Special additives can turn a universal self-leveling floor into a unique one. For example, a solution can acquire the properties of a heater or sound insulator, become frost-resistant or fireproof.

Professional advice

The self-leveling floor will delight you with an impeccable look and a long service life if:

  • The base is well prepared. When applying the mortar to a cement screed, it should be leveled, cleaned of dust and greasy stains. Otherwise, delamination will occur on dusty and contaminated areas.
  • When working temperature maintained … Floors must not be poured at subzero temperatures. There may be ice crystals in the solution. When the temperature rises, they will melt and the structure of the floor will be disturbed. Heat also negatively affects the composition of the mixture. Excessive setting of the mortar at high temperatures leads to its heterogeneity.

It is better to carry out the work together. One person makes the mixture, the second pours and levels it. The composition begins to harden within half an hour. If time is lost, the mixture will become unusable, which will incur additional costs

Do not be afraid of the high cost of a self-leveling floor. A reliable, beautiful and practical coating simply cannot be cheap. And if you count on the duration of its service life (at least 20 years), it turns out that the price is not high at all.
