Concrete surfaces, including the floor, prefer not to paint, and left in its original form.However, even such a strong material such as concrete, exposed to mechanical damage, chipping and chemical resistance.Therefore, the procedure painted concrete floor is not just a job for improving space and a way to protect the coating.That's just more to be seen than to paint a concrete floor?

protection of concrete floors Concrete floors
today often build up in the industrial or commercial buildings.But at the same time can be seen in home workshops, garages, cellars, outbuildings and storage.Though very concrete and can withstand adverse conditions when using a large load, but still requir
different high porosity, low tensile strength, so the influence of external factors on its exposed surface wears, shelled, then there is a characteristic dust.It occurs most often in the case of low-quality concrete, stacking technology violation, improper mixing a mixture of poor application of the cement.
To protect the concrete surface is common to use special formulations.In addition to the decorative properties of paint concrete floor provides protection from destruction, the influence of aggressive media and abrasion, adds additional features such as hygiene, antiskid, decontaminated, antistatic, smoothes irregularities, masks various defects sex - chips, cracks, shells and cavities.
Choosing paint for concrete
For coloring concrete floor is usually used epoxy and alkyd paints, which have unique antislip and antistatic properties, and high resistance to chemicals.Epoxy material needed to prepare, stir and tinted before use alkyd do not need to prepare for the operation.But before working with alkyd paint the concrete surface is primed with epoxy paint does not require it.
addition to colors, are widely used soil mixtures, which are intended to transform rather running the floor.Toning give concrete impregnation bright color coating.The polymer compositions can hide any defects and to level the surface, the use of special fillers allows anyone to make a monolithic concrete floor.To provide additional help decorative floor glitters and flocks that do not fade with time.
choosing which paint is best for concrete floor, it is recommended to take into account characteristics of the premises.For example, in industrial areas, where it is often possible mechanical damage or shock loads on the kinds of surface coating requires the establishment of reliability.In this case, it is best to apply the wear-resistant paint.
for thin-liquid coatings civil choosing nail concrete floor or polyurethane enamel.To finish the floor in the garage, and the treatment of concrete elements of landscape design used tools that are designed to cover the various production facilities, which are at the heart of solvents and epoxy enamel.
to paint a concrete floor in a residential area, you must take part with a water base.Surface coating on balconies and in the corridors is better to buy two-component polyurethane elastomers.If you need a waterproof coat, give preference to one-component polyurethane dyes.Then consider the advantages of each type of dye composition to the concrete floor.
Epoxy paint is very strong and durable coating that extends the useful life of the floor and guarantees a presentable appearance.Such paint is quite resistant to external influences and different chemical environments - acids, alkalis, fuels and lubricants, salt solutions, has waterproofing properties, it can withstand heavy loads and engages well with concrete.
epoxy not abraded and non-yellowing, even if you cover the concrete floor in the hangar, production shops, auto repair shops and car parks.Use this paint can be in the open air, because it is resistant to atmospheric conditions and indoors.Another advantage of this paint - the possibility of applying it directly to the fresh, dried out enough concrete.
The main disadvantage of epoxy paint for concrete floors is its two-component: before using it to mix.Some problems may occur when re-painting.Besides, if you want to change the color of the concrete floor to the other, it will be quite difficult to do.
Acrylic paint Acrylic paint for concrete surfaces is an aqueous composition based on acrylic resin with the addition of various polymers.Such paint prevents the destruction of concrete due to corrosion on the surface creates a protective plastic film, which prevents the different mechanical and chemical influences.
coating which is formed with acrylic paint, quite sturdy and durable, water-resistant and waterproof, so it can help to paint the floor in the garage, basement, balcony and stairs.
Apply acrylic paint - easy and convenient.You can use a brush, roller or spray, and unlike epoxy paint, only one layer, but may be coated with two layers for greater certainty.Time of full drying is 12-14 hours.
polyurethane enamel, as a rule, two-component, however, it does not affect their quality.They are designed for finishing concrete floors indoors and outdoors.Advantages of ink lies in its high weather resistance, economy, environmental friendliness, high hiding power, excellent performance chemical and mechanical strength, the formation of a perfectly smooth glossy surface.
Apply polyurethane enamel is at least 5 degrees above zero and relative humidity not more than 75%.Since the paint is a two-component, to begin with the first component are thoroughly mixed, and then thereto is added second.It is advisable to paint a concrete floor in two phases: Apply a thin uniform layer without spills and drips, re-apply paint, but no later than one day after the first color of the concrete floor.
main drawback of polyurethane enamel - long drying time - 2 - 14 days.This large variation in time explain such moments: the paint does not stick after two days and it is possible to walk across the floor a week finally acquires mechanical strength, and in two weeks - chemical resistance.
If you do not have to paint a concrete floor, the surface can be primed with a polyurethane composition.The primer may be used as the only protective coating, and also for processing directly applying the coating before paint finishing.Primers are polyurethane and epoxy.
polyurethane primer is able to provide a reliable filling of small pores of the concrete, its dust removal and strengthening, as well as excellent adhesive property coated.This material is resistant to gasoline, detergents, chemicals, fats, oils and precipitation.
Judging by the title, polyurethane primer is applied prior to the application of polyurethane enamel, because they have almost identical compositions.However, the paint can be used only 12 hours after the completion of the priming the floor.The advantages of this primer - in convenience and ease of application, reducing the consumption of the final coating, improving the adhesion of topcoat.
epoxy primer suited for the treatment of concrete surfaces before applying epoxy paint on it.But this is also common to use a primer and as a separate coating, which ensures the closure of all the pores and cells in the concrete, as well as dust removal and strengthening of the floor surface.
Advantages of epoxy primer - water-resistance, water resistance, improved adhesion of the topcoat, and resistance to mechanical wear and chemical agents.Before applying the epoxy primer the concrete surface must be sanded and clean with a dust and debris.Please be aware that for 20-30 minutes, the material is able to lose its quality, so it must be applied fairly quickly.
painting concrete floor
you are already familiar with the destiny of each composition and find out the price of paint to the concrete floor, and find out what is better to use for painting concrete floor.No matter what you choose to paint the surface, the technology of its application is practically the same at all times.First you need to prepare the base, remove dust and dirt, then - primed concrete surface and putty all the irregularities, and only after that can be painted.Remember that the concrete floors are usually made of the coating composition in stages - from 2 to 4 layers.
Operating properties and durability of the painted concrete floor depend primarily on the quality of surface preparation.Make sure to start on the floor in the absence of dirt, debris, old paint, stains, paints, and fuels and lubricants, as well as bitumen.Traces of such liquid will be removed with detergents.The water on the concrete floor must not gather in drops.
should also be removed from the concrete floor litter.Then you need to be repaired and zashpatlevat all existing pit, and then spend grinding with special grinding machines.This procedure helps to improve the adhesion of the paint layer and the base.
To get rid of dust, you can use a vacuum cleaner or an ordinary broom.As practice shows, are equally pylyat all concrete floors.To prevent this process is necessary to make concrete cover and dedusting process the top layer.Dedusting is performed by using different compositions of polymers which not only protect the floor from the presence of dust and abrasive wear and abrasion.
Reinforce concrete surface impregnation of the reinforcing type, called toppings.These substances are represented in the form of dry mixtures of silica, cement and other fillers, as well as plasticizers and colorants.These toppings can also be used with decorative intentions, so your concrete floor becomes glossy and smooth.
Ingredients topping clog the pores of the concrete floor, preventing the penetration of harmful components in the surface and ensuring the stability and strength of the concrete structure, making it easy to operate, which saves money for the care of the coating.This tool is applied on a surface made 7 days after its installation.Use of the reinforcing destination enhance coating strength and dedusted 5 years.
concrete floor primer
to provide quality adhesion of the concrete floor and paint, previously recommended to cover the surface of the primer.There are many types of drugs (Beolyuks Aqua, GRID), which can be used in air and indoors.This quick-drying acrylic materials that are relatively resistant to oils, petrol, saline solutions, detergents, mineral composition and water.
For priming is common to use foam rollers to allow well-distributed structure on the surface of the floor.Apply primer so.The composition is stirred, if necessary, diluted to 3% by weight of the primer.The substance is recommended to add the quartz sand to avoid the occurrence of the effect of the slippery floor - up to 10% by weight of the primer.
primer must be applied as one or two layers on a dry, clean coating using roller, brush or sprayer.Use recommended composition at a temperature of 5 - 40 degrees above zero and a relative humidity of 85%.
Have you already decided what to paint a concrete floor, you now need to decide how to use the tool in the work - a roller, brush or sprayer.Selecting dye will depend on what was selected coloring formulation.Paint spray tool is applied in one layer which is able to replace 3 layers that are applied in the usual manner.This technique of applying the paint is quite simple, economical and takes little time.
For spray remember that with it you will be able to handle the bulk of the concrete surface, and other hard to reach places and corners have to paint an ordinary paint brush.The thickness of the paint is only 0.2 millimeter.
Acrylic paint and enamel on the surface of the floor is applied with a roller.Suitable for this wide, which are rather short nap - simple facade and velor cushions that allow you to apply paint evenly and quickly.To make it easy to work, it is worth fixing roller with a long handle.In order to paint the corners, use a small narrow brush.
The painting is carried out at a concrete floor surface temperature of not less than 5, the room temperature at least 10 degrees above zero and relative humidity not more than 80%.Aqueous polyurethane paint while working does not emit odors and flammable.Packaging tools and washed out with water.
permitted to carry out fresh paint or wet concrete, but no earlier than 5 days after pouring.During application of the concrete floor primarily applied smears taken in different directions, then triturated paint on the surface.The layers of the coloring composition should not be too thick: thin layers dry faster and look better.
Create thicker layers results in a long drying time of the coating.Make sure that the previous layer is completely dry, and only then proceed to the application of the next layer of paint tools.Application of the second layer is allowed only after 24 hours.
After the staining procedure of the concrete floor is recommended to wait until the ink is completely dried out composition.This process should take place at a humidity of 70-80% and an air temperature of 18-20 degrees plus.Just after 3 days permitted mechanical load, but if the conditions are different from those shown, the process of drying concrete floor may take longer or faster occur.
coating drying time also depends on the conditions under which the paint is applied.For example, if a coloring material was applied to the fresh concrete, the drying time will increase significantly.Under normal conditions, polymerization coating finally comes about on the seventh day, when they reach the maximum performance of the mechanical and chemical stability.So take your time as soon as possible to use the surface, let it completely dry, it acquired due to wear.
Thus, paint for concrete is able to increase the strength of the coating to protect it from dust and waterproofing to increase ties.But all this is achievable only if the commission of a correct choice of the coloring composition.Also of great importance is consistency and competent execution of all stages of painting a concrete floor.
