Painting concrete floor: what paint is best to use for maximum efficiency

Painting concrete floors

As a rule, concrete surfaces, and in particularfloor, prefer not to paint, and left in its original form. But even such a strong material is subject to chipping, mechanical damage and chemical attack. Therefore, painting concrete floor - it's not just work on beautification of the premises and, above all, a way of protection. That's just what to paint concrete and whether it is necessary to do it? Let's try to sort out this issue.

Epoxy paint: advantages, disadvantages

Epoxy paint for concrete floors - superstrong and durable coating that will extend the life of the concrete floor and gives it presentable. This paint is quite resistant to various external influences and capable of withstanding heavy loads. In addition, the epoxy is not used up, even under the condition that it will be covered with flooring in production halls, hangars, repair shops, stairs and parking lots.

It can be applied not only in the closedindoors, but outdoors, since epoxy paint is resistant to adverse weather conditions. Another advantage of this ink is the fact that it can be applied directly on the fresh concrete, which is still not dried out, thus the quality of the base is greatly improved.

Advantages of epoxy paint:

  • non-yellowing with time
  • It has high waterproofing properties
  • perfectly adheres to the surface of the concrete
  • resistant to various chemicals - acids, alkalis, fuels and lubricants, salt solutions
  • environmental friendliness.

Disadvantages:

  • two-component - before using epoxy paint you have to mix it
  • some problems with repeated staining. If you decide to change the color of the floor to the other, then this would be quite difficult.

Apply the epoxy paint is recommended in two thin layers, setting time which is from 12 to 24 hours.

Characteristics of the acrylic dye

Acrylic paint for concrete surfaces is an aqueous composition based on acrylic resins with the addition of various polymers.

The paint prevents the destruction of concretefloor, creates a protective polymer film that prevents various chemical and mechanical stress. The coating formed of acrylic paint is quite sturdy and durable, so it can be safely painted floors in garages, basements, balconies, stairs, etc.

The advantages of acrylic paint for concrete surfaces:

  • Reliable protection of concrete from corrosion
  • improved weatherability
  • environmental friendliness
  • simplicity and ease of application
  • drying speed
  • moisture resistance and water resistance.

Apply acrylic paint on concrete as possible andbrush and paint roller and spray, and unlike epoxy, it will be enough of one layer, but for greater certainty, you can cover the floor with two layers of paint - will not be worse.

Complete drying time - 12-14 hours.

Polyurethane enamel for concrete floors

As a rule, two-component polyurethane enamel, although it does nor diminish their quality. They are intended for finishing concrete, indoors and out.

paint Advantages:

  • high weather resistance
  • economy
  • environmental friendliness
  • High opacity
  • Excellent mechanical and chemical resistance
  • It can be used for dyeing wood and metal surfaces, and also asphalt
  • It forms a perfectly smooth glossy surface

Disadvantages:

  • long drying time

Apply polyurethane enamel can be ata minimum temperature of + 5 ° C and a relative humidity of 75%. Since the two-component paint, then you first need to thoroughly mix the first component, and then add a second. After re-mixing procedure of paint ready for use.

It is desirable to paint the floor in two stages: first - apply a thin uniform layer of paint, preventing drips and spills, and the second - to put the paint again, but not later than 24 hours after the first dyeing.

Polyurethane enamel

Polyurethane Enamel is recommended to be applied in two stages, between which is necessary to sustain technological break

The drying time of polyurethane paint - from 2 to14 days. such a large variation in time due to the following factors: 2 days the paint does not stick and it is possible to walk through the 7 days on it flooring acquires final mechanical resistance, and after 14 days - the chemical.

As a protective primer

If you have no means for coloring concretesex, you can simply primed. The primer may be applied as a protective coating only, and for pretreatment of the surface before applying it to the finish paint.

Primers for concrete are of two types:

  1. polyurethane primer
  2. epoxy primer

What attracted polyurethane formulations

Polyurethane coating ensures reliablefilling of small pores, hardening and dust removal of concrete, as well as high adhesive property to the surface. This tool is resistant to gasoline, chemicals, detergents, oils, fats and precipitation.

Benefits:

  • simplicity and ease of application - by brush or roller
  • reduces the consumption of topcoat
  • improves the adhesion of the topcoat
  • cured moisture contained in the air

Judging by the name, it can be concluded that such a primer is used prior to painting polyurethane enamels. This is true, because the compositions they are almost identical.

Before applying the primer on the concrete floor of his need to be thoroughly cleaned of debris and dust, as well as to ensure its dryness.

The primer is applied with a short fur rollerbristle brush or a thin layer. At the same time, try to avoid spills and drips to the surface looked smooth. If the soil absorbed unevenly, you can repeat the procedure.

If you decide to use paint, it can be applied only after 12 hours after the completion of the priming of the floor.

Advantages epoxy primer

Epoxy primer designed for the treatment of concrete surfaces prior to coating them with epoxy paint. But you can use it as an independent coating.

This primer provides a reliable closure of all cells and pores in the concrete, as well as de-dusting and strengthens the surface of the floor.

Benefits:

  • water-resistant
  • waterproof
  • improves the adhesion of the topcoat
  • It makes the surface more solid
  • resistant to chemical agents and mechanical wear
  • resistant to water

In addition to concrete epoxy primer is ideal for the treatment of metal and ceramic surfaces and in general, it is indispensable for those bases which have a low absorbency.

Before applying the epoxy primer should be sanded concrete surface and remove any dust and debris. The substrate must be perfectly clean and dry.

Apply primer need a rubber spatula orroll with not too long nap. The main thing here - to hurry, as the material for 20-30 minutes will lose its quality, so do not pull the time, and proceed.

Determine the choice of protective and decorative composition? It remains only to choose the appropriate coating color, combined with interior design or landscape design.

To summarize: for the protection of concrete floors, there are not so little variety of means, but the choice is still yours. Of course, you generally can opt out of any manipulation, that's just keep in mind that nothing concrete is processed quickly begins to crumble, and on its surface (especially garage) there are various spots of gasoline, oil and other substances. While stained concrete floor is able to please you with a pleasant gloss and clarity for many years.
