Types of paint

What is painting?

The paint is a fluid product that after being applied on a surface in thin layers, is transformed into a solid film that adheres to said surface, coating, protecting and decorating the element on which it has been applied.

The paints can be classified into two large groups: water and solvent.

Solvent paints

These paintings present different aspects: bright, satin, matt.

  • Oil-synthetic paints are those that are applied mainly outdoors. In general, they are identified as having a tendency to yellow and taking a considerable time to dry. These products are also known as “oil paint”.
  • Interior-exterior enamels : these are those coatings characterized by being bright and smooth. These are composed of fine pigments (such as titanium dioxide) and well dispersed, as well as highly extensible resins, which dissolve in an alkyd base. When looking for this product for interior surfaces, usually choose glazes with greater hardness, to resist friction and abrasion. For exteriors, however, paintings with greater elasticity are needed, which helps to resist outdoors.
  • Matte and satin enamels: this variant is also alkyd-based, but it is used less because there is little splicing at the time of application. The glazes satinados or lacquers are very chosen by the painters because they are combined with poliuretanos and other classes resins that have greater hardness and that count on a simpler application.
  • Varnishes : they are chosen basically for surfaces that are made of wood. These are filmogens that have significant adhesion, elasticity and have an important resistance to abrasion.

Water paints

These paints must meet three fundamental conditions: covering power or opacity , whiteness and price , in addition to other qualities such as performance, resistance to washing and aging of the product.

  • Silicate paint : has an enormous performance. They are chosen for outdoors since they are very resistant to light and to the degradation of algae and fungi. This is because they produce a continuous film on the surface, which prevents it from peeling off. This painting is characterized by a long time, by not getting dirty, by being permeable to water vapor and silicification. In any case, it is important to clarify that the variety of colors offered in the market is quite limited, this is because it can not be mixed with pigments.
  • The emulsion : it is a suspension of drops of a liquid, which is not miscible with water. At the moment when the drops evaporate, they merge and form a film that allows the passage of water vapor, but not water. This causes that it transpires although it does not allow the entrance of the precipitations. In general they are used as plastic paint. The most common in the industry are:
    • Pure acrylics : this variant is used for water-based enamels. They are characterized by being resistant to yellowing.
    • Styrene acrylics : these paints have a high concentration of pigments. In addition, with the passage of time they obtain hardness and resistance to washing. It is important to clarify that they do not get dirty very much and do not leave visible streaks.
    • Acrylic vinyl : they are similar to the previous ones, but resistance to washing is lower and they stain more.
    • Vinil veova : also known as “autolavable” they get dirty very little.

High decoration coatings

Special mention should be made of the so-called high decoration coatings , due to their increasingly widespread use:

  • Stuccoes to lime : they are made with lime carbonate, and are exposed to temperatures around 900 ° C. They can be used both indoors and outdoors and, when they dry, they acquire a stone-like appearance and are very breathable. This product imitates marble finishes.
  • Venetian Stucco : are lime-based coatings, and are used mostly on flat surfaces indoors. They stand out for their color blurs, which resemble those that were made in ancient times.
  • Veladura antigua : it is a translucent finish varnish that tries to be the imitation + pm of a false Italian stucco.
  • Multicolor coating : they are made with colored acrylic resins with polychromatic particles. This generates particular decorative effects. In addition, it is an easy to wash product and is often used indoors to highlight the beauty of an environment, giving it the appearance of marble, mottled, wrinkled and multi-colored polychrome.
