The building materials market is currently rich in a wide range of paints required for renovation work.

When choosing a coloring product, one may encounter some difficulties caused by ignorance of the characteristic features, properties and differences of different types of paints.

To determine which dye to give preference to - water-dispersion or water-based, it is recommended to take into account the technical characteristics of each type and find the differences.

Distinctive properties

There are a number of factors to consider before choosing a paint:

  • composition;
  • specific gravity;
  • specifics of spending;
  • service life of the coating.

Dispersion

The composition of such a coating includes aqueous dispersions, as well as binder components made of acrylic, latex or polyvinyl acetate. The scope of use, the strength of the dye and its resistance to moisture directly depend on these components.

The most affordable option is polyvinyl acetate-based water-based paint, which is used for painting various kinds of ceilings. It cannot be used in the bathroom or in the kitchen, because this type of paint does not have high moisture-resistant properties. This coating has another significant drawback - the tendency to the rapid appearance of stains and dirt.

The coating, created by latex water-dispersion paint, is durable and resistant to dirt formation.

With the best protection properties and perfect resistance to atmospheric conditions that can cause negative consequences, acrylic water-dispersion paint can be used for painting both the inside and the outside of the building.

It can be applied to walls and ceilings made of concrete and wood. Such a surface is absolutely not afraid of high humidity.

When using water-dispersion paints, it is necessary to take into account their unique properties, the main of which are:

  • the air temperature during their application must be more than + 5 ° С;
  • complete drying occurs after a couple of hours after coating;
  • the ability to flawlessly fill small cracks and crevices with a dye;
  • no need to prepare surfaces before using paint.

An aqueous dispersion coating has many advantages. The most important of them can be distinguished:

  • reliability and long service life;
  • breathability;
  • resistance to temperature extremes, moisture and other environmental influences;
  • resistance to aggressive household chemicals - detergents and cleaning agents;
  • absence of harmful substances in the composition;
  • the ability to combine with all types of surfaces (except for metal, since connection with it can lead to corrosion);
  • lack of a pungent odor;
  • relatively fast drying of the surface - before applying a new layer after the previous one, it is enough to wait just one hour.

Emulsion

Water-based paint has an aqueous composition with additional pigment and polymer particles present in it. In some cases, mineral, acrylic or silicone resins may be present. Solvents added in different proportions can change the structure of such a coating.

The consumption of water-based dye is approximately 210 ml of substance per 1 sq. m of the area to be painted. But this is a conditional meaning, since the indicator tends to change in accordance with the type of surface, breeding method and other circumstances. The specific weight of the coating assumes no more than 1.5 kg.

Among the main advantages that water-based paint possesses are:

  • lack of a pungent odor;
  • the dye has special properties that allow the coating to dry quickly after application;
  • an easy and simple coating method is provided due to the unique consistency;
  • the ability to change color using special pigments - colors;
  • the ability to mask darkened areas on the wall with a single pass with a roller or with one spray of a spray gun;
  • walls that are covered with a water emulsion in any way are completely painted with the composition, without forming smudges or traces from brushes, rollers and other devices intended for this purpose;
  • a wide range of tools for painting surfaces with this type of paint;
  • affordable price.

However, water-based paint has small drawbacks, which are recommended to pay attention to when choosing it:

  • The paint base contains a large amount of water, so it is not recommended to paint metal or glossy surfaces with it.
  • Unfortunately, there are many fakes, since the manufacture of water-based paint is not particularly difficult. Fake dye may smear on after drying and form visible layers. Therefore, it is better to buy dyeing products of proven brands in specialized stores.

Known mineral, acrylic, silicone and silicate water-based paints, differing from each other in the scope and unique composition.

The most accessible and low-cost variety of paints remains mineral water-based coatings, consisting of cement or hydrated lime. They can be applied to various surfaces, but this type of paint is not characterized by durability.

The most popular and versatile option in high demand is an acrylic water-based paint suitable for wood, plaster, brick and concrete surfaces, as well as metal and glass.

An expensive subspecies of water-based paint is a silicone coating, the constituent elements of which are high quality silicone resins. You can use this type of coating on any surfaces.

Use silicate water-based coatings, which contain water glass and coloring pigments, preferably in rooms with high humidity levels.

Differences

Despite the similarity of names, the difference between water-based and water-dispersion coatings is obvious:

  • Dispersion assumes the presence of the smallest particles in the base. If such particles take the form of a liquid, then we are talking about an emulsion.
  • Water-based paint is harder and more resistant to damage, which is not the case with water-based paint. The cost of water-based paints is often higher.
  • Water-based paint is reliable and water-resistant, while water-based paint is easy to wash off.
  • Water-based paint has a wide range of various shades, water-dispersion coating is available in only one color - white.
  • Water-dispersion materials must be diluted with water, emulsion materials need to be diluted with organic solvents.

Knowing the distinctive properties and benefits of both types of paints guarantees the correct choice of paint coating.
