Typically, concrete surfaces, in particular floors, prefer not to be painted, 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 a job for improving space and, above all, a way of protection.That's just what to paint concrete and whether to do it at all?Let's try to sort out this issue.

Epoxy paint: advantages, disadvantages ↑

ion that it will be covered with flooring in the production halls, hangars, repair shops, stairs and parking.

apply it possible not only indoors but also outdoors as epoxy paint resistant to adverse weather conditions.Another advantage of this ink is the fact that it can be applied directly on the fresh concrete that is still not dried out, thus the quality of the base is significantly improved.

advantages of epoxy paint:

  • does not yellow over time
  • has high waterproofing properties
  • perfectly adheres to the surface of the concrete
  • resistant to various chemicals - acids, alkalis.fuels and lubricants, salt solutions
  • ecology.

Disadvantages:

  • two-component - before using epoxy paint you have to mix it
  • some problems when re-staining.If you decide to change the color of the floor on the other, it will make it quite difficult.

Apply epoxy paint is recommended in two thin layers, setting time which is between 12 and 24 hours.

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

advantages of acrylic paint for concrete surfaces:

  • reliable protection of concrete from corrosion
  • increased weathering
  • environmental
  • simplicity and ease of application
  • bystrta drying
  • humidity and water resistance.

Apply acrylic paint on concrete can and brush and roller, and spray, and unlike epoxy, it will be enough of one layer, but just to make sure you can cover the floor with two layers of paint - will not be worse.

complete drying time - 12-14 hours.

polyurethane enamel for concrete floor ↑

As a rule, two-component polyurethane enamel, but it does no diminish their quality.They are intended for finishing concrete and indoor and outdoor.

Benefits paint:

  • high weatherability
  • economy
  • environmental
  • high opacity
  • Excellent mechanical and chemical durability
  • can be used for painting wooden and metal surfaces, as well as asphalt
  • formsperfectly smooth glossy surface
Disadvantages:
  • long drying time
Apply polyurethane enamel is possible with a 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 the second.After the procedure, re-mixing the paint is ready for use.

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

Polyurethane Enamel
polyurethane enamel is recommended to apply in two stages, between which is necessary to sustain technological break
polyurethane paint drying time - from 2 to 14 days.such a large variation in time due to the following factors: 2 days the paint does not stick and it is possible for her to go through the 7 days flooring acquires final mechanical resistance, and after 14 days - the chemical.

primer as protection ↑

If you do not have funds for painting concrete floor, it can simply be primed.The primer may be applied as a sole protective coating, as well as for surface pretreatment prior to application of the paint finish on it.

Primers for concrete are of two types:

  1. polyurethane primer
  2. epoxy primer

What attracted polyurethane formulations ↑

polyurethane primer provides a reliable filling of small pores, dust removal and strengthening of concrete, as well as high adhesive property to the surface.This tool is resistant to gasoline, chemicals, detergents, oil, grease and precipitation.

Benefits:

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

If we judge by name, it can beconclude that such a primer before painting using polyurethane enamels.This is true, because the compositions they are almost identical.

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

advantages of epoxy primer ↑

Epoxy primer is intended for the treatment of concrete surfaces before applying epoxy paint on them.But you can use it as an independent coating.

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

Benefits:

  • waterproof
  • waterproof
  • improves the adhesion of the topcoat
  • makes the surface more durable
  • resistant to chemicals and mechanical wear
  • resistant to water

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 low absorption.

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 or a roller 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 act.
