Why do you need to paint a concrete floor

A concrete floor is, of course, a sturdy, dependable, and long-lasting foundation. However, this coating is susceptible to different mechanical influences based on its intended use.

It is also impacted by harsh environments and weather patterns, which over time may cause it to lose its functional and aesthetic qualities and develop chips, cracks, scratches, and dust accumulation.

In addition to human factors that cause surface wear, such as using subpar parts, breaking the foundation device’s technology, and making calculation mistakes, concrete itself has a relatively high porosity, which allows moisture to seep inside and destroy the material, as well as a low tensile strength.

Particularly prone to wear is the structure’s top layer. Concrete shrinks as it solidifies, resulting in the formation of a brittle crust known as "cement milk" on the surface. After a while, the foundation starts to dust and peel off, which deteriorates the floor’s aesthetic appeal and has negative health effects on mucous membranes and the respiratory system in people.

Painting the surface is one way to improve a concrete floor’s resistance to loads and moisture, strengthen the surface layer, and prevent dust accumulation.

What characteristics ought a paint for concrete floors to possess?

• Durability.
• Resistance to mechanical loads.
• Resistance to climate and, if necessary, chemical compounds.
• Good adhesion to the concrete base.
• Acceptable decorative qualities.

Let’s look at the composition options that different paint and varnish manufacturers provide.

Types of paints for concrete floors

Paints are classified into the following categories based on how the painted surface is being used:

1. compositions for outdoor work;
2. coatings for indoor work.

Paints designed for outdoor use are more resilient to the negative effects of different environmental conditions. Paints are primarily categorized based on the substance that forms the film, which establishes the primary characteristics of the coating.

Let’s think about the type of concrete floor paint that can be used depending on the material that makes up the film. The compositions have different qualities, and each has pros and cons of its own.

The protection of concrete structures is advised by GOST 31384-2008 for the following composition types: alkyd, epoxy, nitrocellulose, organosilicon, organosilicate, rubber, perchlorovinyl, acrylic, urethane, polyurethane, and combined coating systems.

GOST 926-82 "PF-133 Enamel," GOST 6465-76 "PF-115 Enamels," GOST 6631-74 "NC-132 Enamels," GOST 7313-75 "HV-785 Enamels and HV-784 Varnish," and GOST 23494-79 "HS-059 Primer, HS-759 Enamels, HS-724 Varnish" are some of the paint types that are produced in accordance with GOST for concrete floors. However, the majority of concrete paints and varnishes are produced in accordance with the manufacturer’s specifications.

Now let’s look at the most widely used protective substances:

Two-component: according to the directions on the container, the paint and hardener must be combined in the exact amounts before using. Both indoor and outdoor use are acceptable for the compounds. They develop on a long-lasting, moisture-resistant, non-slip layer of concrete that also perfectly withstands the effects of acids, salts, alkalis, oils, and gasoline.

The paint’s ability to be applied to freshly-poured concrete is a significant benefit. One drawback is the limited color palette.

1. Alkyd and alkyd-urethane paints and enamels.

• Paints based on alkyd resins are characterized by good water resistance, resistance to temperature changes.
• The coating is not elastic, so under loads its particles can fly off. The solvents used in the production of these paints emit an unpleasant odor, so you should evaluate the possibility of using such a composition in residential premises.

1. Acrylic paints.

These coatings are made solely from water and without the addition of solvents. Acrylic resins function as a connecting component.

• Durability and strength.
• Abrasion resistance.
• Resistance to moisture and detergents.
• Temperature resistance.

Crucial! Polyurethane compounds or water-based paints work better in residential settings.

• The coating can be one- or two-component.
• These compositions form a very attractive layer, visually reminiscent of self-leveling floors.
• The paint is durable, resistant to all types of impacts and temperature changes.
• It can be applied at sub-zero temperatures (up to -10 degrees).
• There is no unpleasant odor during application and after completion of work.
• The polyurethane coating does not slip.

It is important to remember that the polyurethane coating takes a while to dry. However, there have been compositions recently that, after application, allow you to walk on the floor after 24 hours, such as the paint "Polybetol" (shown in the picture).

• Paint with a matte effect, which has excellent wear resistance, reliably protects concrete surfaces from mechanical damage and precipitation, extends the service life of the base.
• The coating can be applied at subzero temperatures.
• Drying time is only a few hours.
• The coated floor can be washed using detergents; short-term exposure to alkalis, gasoline and oils is allowed.
• The paint is recommended for use both indoors and outdoors.

1. Rubber paints.

Rubber compounds have good shock load resistance, are elastic, resistant to mold and fungus, and resistant to wear and moisture. The paints dry quickly—no more than an hour—and maintain their qualities in temperatures between -50 and +50 degrees. But their price is out of the budget range, and their color selection isn’t sophisticated enough.

Matte or glossy coatings are available. Although a shiny floor appears more appealing, dirt and scratches are more noticeable on it.

Based on the paints’ stated qualities, the state of the object to be painted, and their personal budget, each person must decide which paint to use.

Counseling! Polyurethane compounds and epoxy resin paints are viable options for industrial floor surfaces that need to be dependable and resistant to heavy impacts. Acrylic enamel is a good choice for residential properties.
