Water-dispersible acrylic paint and its technical characteristics Water-dispersive acrylic paint VD-AK : application, advantages and disadvantages

There is such a material that modern buyers choose for processing a wide variety of surfaces - this is water-dispersion acrylic paints.

They are made on the basis of an aqueous dispersion of copolymers, and such compositions for coloring are distinguished by excellent properties as well as excellent technical characteristics. In this article, we will consider their distinctive qualities, as well as features of their application.

Paint composition. Acrylic water-dispersive paints and varnishes are distinguished by excellent environmental friendliness, since they are diluted only with pure water.

General information

They also do not contain organic solvents, and the filler of this type of paint is chalk, marble flour, talc, and also binders that help to give the coating strength, as well as dyes (pigments). Most people often confuse acrylic paint with acrylate paint, but these colorants differ greatly in composition.

Please note that additives and impurities are not used in acrylic-based materials, and there are special dispersions in acrylate varieties. This difference should be taken into account when choosing really suitable coloring compositions.

Advantages

Acrylic-based paints have a large number of advantages.

Let's consider the main advantages of such materials:

  1. Water-dispersible acrylic paint and its technical characteristics Increased degree of resistance to abrasion, as well as long service life. Most types of coatings last up to 25 years, and the surface will not lose its visual appeal.
  2. Such compositions can be used for external and internal decoration.
  3. The coatings have excellent adhesion and can be used on a wide variety of surfaces - primed, wood, plasterboard, concrete and brick. They can also be applied to plaster surfaces.

  4. Applying acrylic-based paints and varnishes is quite simple and even for beginners. This can be done without the use of expensive fixtures and professional skills.
  5. Such compositions for coloring are distinguished by fire safety, resistance to temperature extremes, and they also do not crack in the cold.
  6. The reaction to ultraviolet radiation in such a coating is completely absent, and therefore it will remain bright for a long time.
  7. Acrylic based formulations allow air to circulate in a natural way, and mold will not appear in such a room, because the surfaces will breathe.

  8. After hardening, the acrylic film will become resistant to liquid, and for this reason, paints and varnishes can be used in the bathroom and kitchen, and the coating is also perfectly washed from dirt.
  9. Polyacrylic paint has excellent hiding power.
  10. The drying time is from 30 minutes to several hours, so you won't have to wait long to apply the next coat.

When the fresh coating dries out, evaporation occurs, and only water "leaves". Such an interior type paint does not have an unpleasant odor.

Disadvantages

There are several factors that, in certain cases, can become a real obstacle when using water-dispersion acrylic paint.

It is not necessary to apply coloring compounds under certain conditions, and it is worth highlighting the main ones:

  1. Strong wind - due to strong wind gusts, the coating will be dry unevenly, and irregularities may even appear on the processing surface!
  2. Very high humidity - in no case should it be more than 80%, otherwise the liquid will not evaporate.
  3. Precipitation (even small) - the fresh coating should in no case be exposed to precipitation for at least the first day, that is, 24 hours.
  4. Exposure to the scorching sun - the rays of the sun will distribute paint unevenly over the treated surface, and may also cause spots, bumps and streaks.
  5. The film that protects the base will not be able to form if the temperature is very low.

    Cracks may appear in the coating.

Scope

Such paint-and-varnish materials are often used to paint facade walls. This is a great option for painting a building in a city setting. In megacities, the atmosphere is highly polluted, and acrylic-type coatings are distinguished by the property of repelling pollution. Such paints perfectly help to protect the base from the formation of rust, and this is an important advantage for coatings that are used for exterior decoration.

In order for the coloring composition to help prevent the appearance of fungus and mold, it is worth adding components such as antiseptics to them. These paints and varnishes are perfect for use in a room with a high level of humidity, and paints on an acrylic base can be applied even to the floor surface. But this should be done only if the floor-type coating is not subjected to heavy loads.

How to choose the best paints?

To find paints and varnishes that are ideal for a particular situation, you should read the customer reviews on the site, and also listen to the recommendations of specialists. You should also make sure that all relevant certifications are included with the product.

Otherwise, you may end up with low quality materials. We do not recommend opting for coatings with different colors. High quality water-dispersible acrylic colorants are generally white.It is whiteness that is an indicator of the reliability and durability of the paint and varnish material. Some manufacturers who are unscrupulous add color to such a paint, thus trying to hide its flaws.

Please note that it is better to obtain the required color with your own hands after making a purchase. In any case, the paint and varnish material will need to be diluted with water, and you can add color when performing this process.

How to work properly with the material

It is quite simple to apply water-dispersible acrylic paint, and in order to achieve a perfect result in the end, care should be taken to thoroughly prepare the base before applying the paint and varnish material. The complexity of this process will depend on the specific state of the surface. If she does not need preparatory work, she will need to be patient and persistent.

Preparatory stage

First, remove all dirt and thoroughly wash the surface. If you have old paint-and-varnish type material (for example, with cracks and bubbles), it should be cleaned using a scraper or even a spatula.

If the case is extremely difficult (for example, a coloring oil composition is applied to the concrete surface), the coating should be cleaned with a wire brush or drill, as well as a construction hair dryer. You can also buy an additional remover to help remove old material from the substrate easier and faster. Putty should be applied if the surface has defects (chips, dents and cracks).

When the coating becomes dry, you should remove the irregularities using fine-grained sandpaper.

Next, remove all dust from the surface and apply a primer to it. It is better to pick up a primer with an antiseptic - it will prevent mold. You should also pay attention to solutions with a high penetrating ability - this is to make the surface structure more uniform

Application of paint and varnish

The most suitable and popular device will be a spray gun - with its help, water-dispersion acrylic paints and varnishes can be applied as quickly and easily as possible. However, you can easily choose between simpler tools.

Prepare the following for applying the staining compound:

  • Roller or brushes.
  • Masking tape.
  • Tray for paint product.

Water-dispersible acrylic paint and its technical characteristics To protect from paint spills in places that you will not intend to process (or to delimit areas that will be colored in different shades), you should use adhesive paper tape. To begin with, it is worth painting over hard-to-reach places (corners and joints).

For this, it is better to use a convenient brush, and therefore you can proceed to using a roller.Before that, you should thoroughly impregnate his coat with paint and varnish material.

It should also be remembered to remove excess paint from the tool beforehand. To do this, you need to roll the roller on the tray (this is especially convenient if it has a ribbed surface). When applying paint, roll it from right to left and also from top to bottom.

So the first layer will be uniform and of high quality. Before applying the next layer, the previous one must dry completely. The second time, the staining will be carried out much faster, and the coloring agent will also become much less.

Please note that even two coats of paint are usually sufficient to achieve a rich, uniform layer. Even a third coat of paint can be applied if you wish.

You can make the coating more interesting with additional decor, and for this you can use various devices, including stencils, as well as textured rollers.

Safety and storage considerations

It is recommended to use paints and varnishes in goggles, and before starting work, apply a protective cream to your hands and face. The considered coloring compositions are among the safest for human health. But also do not forget about basic precautions. Water-borne acrylic paints should be stored at a sufficiently high temperature.

Such materials are not suitable for long-term storage in frost (the maximum storage period under such conditions is 1 month). You should learn more about the specific conditions in which you need to store the container with the coloring composition. If the paint is in the wrong place, then after a while it will become thicker, and its properties will greatly deteriorate.

The use of acrylic paint water-dispersion compositions will be a good solution to renovate the facade. This will make it possible to make the interior more interesting, as well as to translate into reality the ideas of creativity.

But the selection of suitable materials should be as careful as possible 0 should give preference to manufacturers who have won the trust of consumers.

Please note that you should make sure in advance that the room is suitable for storing paint and varnish - focus on the degree of illumination, temperature and humidity level.
