Concrete floor: pros and cons

Both benefits and drawbacks can be associated with this coating.

One way to describe it is as follows:

• strength;
• practicality;
• durability;
• environmental friendliness.

Conversely, though:

• such a floor is dusty (the top layer is subject to destruction, mechanical and chemical influences over time lead to the formation of cement dust);
• has poor sound insulation and an unattractive appearance;
• The material in question is cold;
• it absorbs moisture, since it is a hygroscopic material. This can lead to the formation of fungus and mold, and, over time, to the appearance of cracks.

The surface needs to be vacuumed and sanded, regardless of the type of coating that will be applied. We shall thus eliminate the top layer’s weakness.

Let us examine the types of coatings applied to the aforementioned floors:

Coating options

There are a variety of floor covering options and materials available, contingent on the intended use of the space as well as personal preferences.

GOST 31384-2008 governs the use of concrete coating agents and provides guidelines for floor installation in accordance with SNiP 3.04.01-87 "INSULATION AND FINISHING COATINGS" and SNiP 2.03.13-88 "FLOORS."

Applying a primer

The simplest way to reduce dust, fortify and shield the top layer, and improve the appearance of the floor is to apply a primer. The compositions are suitable for serving as the sole base coat.

The primers listed below are suitable for use as primers:

1. Epoxy. Have good waterproofing properties. Epoxy coating is resistant to detergents. Drying time is an hour.
2. Polyurethane. Penetrates deeply into the pores, has good adhesion to concrete. Drying time is 12 hours.
3. Acrylic. The most budget option. Drys within 4 hours.

Painting a concrete base

For concrete floors without higher requirements for heat and noise insulation, paint works great:

Crucial! Use a paint that is similar in composition to the primer that has been applied when applying it.

• Epoxy paint. Resistant to aggressive environments, durable, the coating with applied paint looks good.
• Polyurethane enamel. Forms a perfectly smooth surface, is a well-hiding, environmentally friendly coating.
• Acrylic enamel. Has high moisture resistance.

Self-leveling floors

A highly well-liked wear-resistant coating that stands out for its hygienic qualities, longevity, and fashionable appearance.

It has shortcomings.

• high cost;
• not environmentally friendly (but it practically does not manifest itself in any way, since there will be no harmful emissions);
• excessive smoothness (with such a floor you should be more careful in places where elderly people and small children are).

The image illustrates how using 3D design can result in self-leveling floors.

A composition with the desired characteristics can be selected based on the coating requirements.

• Polyurethane. Due to the inclusion of plasticizers, they have good sound absorption. Available in glossy and matte finishes. Resistant to aggressive environments. Good impact resistance. Best suited for use in residential premises.
• Epoxy. Transparent, which is used in decoration. Abrasion-resistant, but low strength.
• Methyl methacrylate. Dries quickly, has good strength characteristics. But can emit toxic compounds, so they should not be used in crowded places.
• Polymer cement. Waterproof, antistatic properties.
• Acrylic. The least durable of all options.

Floor device

The following equipment will be necessary:

Let’s look at the step-by-step procedure for applying a self-leveling mixture to the surface:

Underneath the final layer is a film that has an applied image to create a 3D effect. Concrete floors covered in a leveling mixture are a great choice for both private residences and public spaces. If required, you can put in a "warm floor" system or thermal insulation underneath it.

Parquet

This content has always been well-liked. This option usually ends up being the most beneficial when it comes to covering an apartment’s concrete floor.

1. Glue sheets of moisture-resistant plywood onto a primed base. Be sure to provide deformation distances of 1.5-2 mm between the sheets.
2. Attach the plywood with dowels.
3. Lay out the soundproofing underlay.
4. Attach the parquet using a tongue-and-groove joint, glue, and in some cases nails.

It is best to do this on paper first to ensure proper pattern formation. Arrange the planks so that the portions that have been cut are situated along the room’s edges.

Sand the newly installed parquet flooring, and use putty to fix any flaws that show up. Next, coat the area with multiple coats of varnish. After the prior layer has fully dried, the next is applied.

Although laying parquet is a laborious task, the outcome should satisfy you.

Roll coverings

Linoleum

In addition to its great qualities, this material is reasonably priced.

The act of manually installing flooring on a concrete floor is not very difficult:

1. Before starting to lay the roll, you need to bring it into the room and lay it on the floor for 12 hours.
2. After that, cut it according to the size of the room, making allowances of 10 cm in case of shrinkage.
3. Apply glue to the inside of the covering and carefully glue the linoleum, smoothing the surface.
4. When laying several strips of material, they are glued together using special glue.
5. In small rooms, it is permissible not to glue the linoleum. It is enough to fix it with skirting boards.

Carpet

Carpet is easy to lay. If the carpet has an elastic backing underneath it, it should be glued before the carpet.

You must glue the flooring to the base when installing it in a large room, even if it is not backed. You can install carpet in small spaces without the need for glue by simply pressing it down with a baseboard.

Laminate

Dependable and reasonably priced content. Laminate makes a fantastic covering. On a concrete base, a backing (typically 3 mm thick foamed polystyrene) should be placed. Tape can be used to bind the backing rows together. Panels may be arranged diagonally, longitudinally, or transversely.

Crucial! One centimeter should separate the laminate from the wall (damper indent).

Locking joints are used to secure the planks to one another. On the side that is closest to the wall, cut off the comb of the first row of panels. The assembly process is done in rows. If required, a hacksaw or jigsaw is used to cut off portions of the panels.

The durability and aesthetic appeal of concrete floors are significantly improved by the finishing coating. You can make sure your floor endures a lot of use and still looks fantastic for many years to come by selecting the appropriate finish.

Benefits of different coatings range from improved stain and chemical resistance to a glossy, polished appearance. For the best results, whether you choose to use polyurethane, epoxy, or another type of finish, proper application is essential.

Don’t forget to properly prep your concrete surface before applying any coatings. This include sanitizing, fixing any flaws or cracks, and making sure the floor dries completely. By following these instructions, the coating will adhere correctly and provide a durable finish.

Adding a finishing coat to your concrete floor project is a wise financial decision. It enhances the visual appeal while adding a protective layer that strengthens and simplifies maintenance for your floor. You can improve the lifespan and functionality of your concrete floors by making well-informed decisions by being aware of the features and application procedures involved in the manufacturing process.

For concrete floors to be more functional, durable, and aesthetically pleasing, finishing coatings are essential. Applying a protective layer that can withstand abrasion, enhance the floor’s aesthetics, and create a smooth, clean surface are all part of this process. The longevity and functionality of the concrete floors in a variety of settings are ensured by being aware of the manufacturing features of these coatings, such as the materials used, application techniques, and curing times.
