Properties of concrete floors
A foundation made of concrete is the most popular and long-lasting type. If you have the bare minimum of tools and materials on hand, you can easily make it yourself. Let’s take a moment to learn about the characteristics of concrete screed.
In its most basic form, a concrete foundation is a floor composed of a binder, which is cement, fillers (sand, gravel, or stone chips), water, and additives. The specifications for a concrete floor can be found in "Floors," SP 29.13330.2011.
Although it’s common in residential buildings, a concrete foundation is essential when there are higher loads.
There are several benefits to using high-quality ingredients and adhering strictly to laying technology when creating concrete floors.
- durability;
- fire resistance;
- resistance to aggressive environments;
- wear resistance and mechanical strength;
- ease of maintenance;
- resistance to humidity and temperature changes;
- safety for human health;
- budget cost.
But because of the cement milk that has solidified, the top layer of the concrete base is delicate. It develops chips and cracks while it’s in use. The worst part is that it starts to dust.
Equipment components may become contaminated by cement dust, reducing the equipment’s lifespan. The health of people is greatly endangered by such dust. It can lead to mucous membrane disorders, allergies, and skin and respiratory conditions. Furthermore, concrete is cold and has an ugly appearance.
You won’t be able to stop at just pouring concrete mixture onto the floor, for this reason. Depending on the conditions of operation and the requirements placed upon it, such a base may undergo additional processing.
Concrete screed must always be polished after it is poured, regardless of whether a finishing coat will be applied. This allows you to get rid of surface imperfections and the brittle upper layer.
Types of polymer coatings
Crucial! Even though this coating is dependable and long-lasting, concrete processing is still required.
When selecting a composition, take into account:
- purpose of the object:
- type of loads that the base will experience;
- operating conditions;
- condition of the concrete floor;
- need for decoration.
Now let’s look at the polymer-based products that can be utilized for concrete bases’ last processing steps.
Polymer impregnation
Applications for organic-based impregnations for dust removal from concrete floors are numerous. Concrete that has been impregnated with polymers goes deeper (2–6 mm) into the base of the concrete, filling and binding the pores in the top layer to increase its durability and resistance to different environments.
Acrylic impregnations
These compounds should be renewed after two to three years because of their short service life. Additionally, substrates that are not subjected to heavy loads are impregnated with acrylic. Nonetheless, they effectively address the issue of dust formation. Furthermore, they have resistance to both moisture and UV light.
Consumption during impregnation: 0.2-0.35 l/sq.m.m.
Polyurethane compounds
This is the most common and affordable method of conception. Concrete can be made much stronger, more resistant to moisture and wear, have its base cleared of dust, and look better by applying polyurethane compounds. Their drawbacks are that they smell strongly and can’t be used in situations where the floor’s humidity level is higher than 5%.
200–400 g/m2 is the average consumption per layer.
Epoxy impregnations
The two-component epoxy mixture shields the concrete surface from moisture, fuel and lubricant effects, and effectively removes dust. It has no smell, but its resistance to loads from such impregnation is marginally worse than polyurethane’s.
Impregnation consumption: 200-300 g / sq.m. Recently, water-epoxy impregnations have appeared, which are characterized by low viscosity, which allows for better penetration into the top layer of concrete.
Latex impregnation
Latex-based compositions are resistant to sunlight and effectively inhibit the formation of dust. They combine to create a coating that offers defense against harsh conditions and abrasives. Since water serves as a solvent, they have no smell. They can be put on recently mixed concrete. They are not appropriate for floors that experience heavy loads, though, just like acrylic.
Impregnation based on PVC resins
These impregnations offer strong resistance to loads and abrasion by penetrating deeply into the concrete’s surface layer. Although they are resilient to harsh conditions and dry quickly, they are not very effective at repelling dirt.
The consumption of composition is 0.2-0.35 l/sq.m. You can add dyes to different kinds of impregnations. These combinations will impart a tint to the concrete floor and improve its aesthetic appeal.
Polymer paint
Since these thin-layer polymer coatings have an application thickness of no more than 500 microns, they are typically applied to surfaces that are not subjected to significant loads.
Painting a concrete floor serves multiple purposes:
- Aesthetic component. Gray concrete does not look very attractive. With the help of paint, you can significantly improve the base.
- Protective functions. Painting will increase the service life of the floor, increase moisture protection, resistance to atmospheric and aggressive environments, increase mechanical strength and hygiene.
- Elimination of minor defects in the form of cracks and smoothing of irregularities.
A concrete surface is primed for painting using a variety of primers.
Crucial! The most dependable method for treating a concrete base is to use the impregnation-primer-paint scheme.
We will compile the details of the most popular paints for concrete surfaces into a table for convenience of comparison:
- abrasion resistance;
- strength;
- fuel and lubricant resistance;
- good adhesion;
- resistance to atmospheric phenomena;

- Recently, a thin-layer polyurethane coating for concrete floors "polymer stone" has become popular for application to working concrete surfaces. It is applied to newly installed concrete floors and to old coatings.
- This composition has increased durability, good penetration into the pores of concrete, greater resistance to chemicals and any type of impact than conventional polyurethane enamel.
- It can be applied without preliminary priming of the floor, as it has increased adhesion. The thickness of the applied film does not exceed 150 microns. The drying time of the floor between layers is no more than 4 hours.
- Heavy loads on the bases are allowed 24 hours after application. As a result of using this composition, a highly durable polymer concrete coating is obtained.
Self-leveling floor
This self-leveling mixture is a highly preferred coating for concrete foundations. Typically, its application has a thickness of 4-5 mm. Once the liquid composition solidifies, a monolithic surface with superior strength properties is created.
Depending on the needs of the landowner, the surface may be textured, smooth, or contain small bits of mineral.
Polyurethane-based floors
Because of their unique chemical and physical characteristics, these coatings have recently gained immense popularity.
- They are suitable for laying on bases that are subject to serious static and dynamic loads.
- Such a polymer coating for concrete floors tolerates temperature changes, the action of direct sunlight, it combines strength and elasticity.
- Polyurethane flooring is fireproof, hygienic, non-slip.
- It has excellent decorative qualities.
- The composition has an unpleasant odor.
- The solution cannot be applied to damp bases.
Epoxy-based floors
Medium-intensity loads are installed in areas with epoxy floors. Both recently laid concrete bases and old concrete screeds can be treated with the material.
- It is allowed to apply the solution to damp concrete.
- The coating is resistant to external influences, chemicals, is not afraid of moisture (epoxy self-leveling floor can be installed outdoors), has high mechanical strength, good dirt-repellent properties, is easy to maintain.
- The resulting base has excellent decorative qualities, is not affected by ultraviolet radiation, is environmentally friendly, fireproof.
- The solution obtained after mixing the components is not viable for too long, so some professionalism is required from people with working with him.
- The coating is quite sensitive to impact loads. When heavy objects fall, cracks may form.
Etal self-leveling floors, which have good performance characteristics and an affordable price, are quite popular in this segment.
Floors on a methyl methacrylate base
The following attributes define this relatively new type of coating:
- The fast-hardening two-component coating is not afraid of moisture, has high resistance to impacts, abrasion, aggressive environments, temperature changes.
- Withstands loads of up to 15 tons per 1 sq.m.
- However, it is almost impossible to apply it yourself, since it dries quickly, and only professionals can achieve a smooth surface.
- When laying, the composition releases toxins.
- In addition, such a self-leveling floor is quite expensive.
Other self-leveling floor types include epoxy-rubber, cement-acrylic, and polyurethane-cement, though they are less popular.
Highly filled polymer floors
After installation, this kind of coating creates an extremely sturdy base that can support heavy transport loads. It is not frightened of moisture, strong materials, or variations in temperature.
Both inside and outside the building, floors are installed. Typically, the coating’s thickness fluctuates between 4 and 10 mm. The mixture consists of quartz sand (corundum can be used in rare instances to replace quartz sand), a polymer fixer, and coloring pigments to add color to the floor if needed.
Device of a self-leveling polymer floor
You’ll need the following equipment to finish the job:
Detailed guidelines for installing a self-leveling floor:
- Preparation of the base.
- If the polymer coating on concrete is to be applied to a freshly laid base, then at least 28 days must pass from the moment of pouring.
- The surface should be cleaned of debris, dirt and dust.
- Defects of the base (cracks, chips, potholes) are sealed with mortar.
- The concrete surface is polished. The debris is collected with a vacuum cleaner.
- The concrete base is primed. For better adhesion, fine quartz sand can be added to the primer. After applying the primer, wait until it dries (about a day). Residual sand is removed with a vacuum cleaner.
- The base layer of the self-leveling floor is installed. The finished polymer solution is poured onto the surface. A squeegee is used to ensure uniform distribution. Air bubbles are removed with a needle roller (as seen in the photo).
- If desired, you can create a decor on this layer. The ideal temperature range for work: +5…+25 degrees.
- After the base layer has dried, a thin finishing layer of polymer is applied. The products of some manufacturers do not require the application of a finishing layer – it is enough to limit yourself to the base.
