Characteristics of water-based paint on the properties, types, applications

Posted by: 17.04.2018

Different types of paints are often used in decorating. And water emulsion, including. By popularity, it goes almost to first place. Lay down smoothly, perfectly covering the entire surface. Buying white water-based paint + color fillers, you do not limit yourself in any framework. Coupled with desire and imagination, you can create a masterpiece on a suitable surface.

Paint composition

The basis are two ingredients: water and water-insoluble polymers. The composition is complemented by plasticizers, pigments and other necessary additives. Since water does not dissolve these polymers, they are present there in the form of mist. Therefore, this paint is an emulsion.

Paint properties

These paints are divided into interior and facade, the determining criterion are their properties. After applying the paint, the water in it evaporates from the surface, and the remaining polymer creates the strongest film. The coating is durable and, surprisingly, is not afraid of water. An important property of paint is environmental friendliness: no fumes containing substances hazardous to humans, no odor, no solvents.

The paint quality falls on almost all types of painted surfaces, but not metal. As part of the water, and it is detrimental to the metal in terms of corrosion.

Types of paint

There are several different polymers used in the composition:

  1. Acrylic polymer (acrylic resin) after applying and drying it turns out plastic film that protects the surface from the environment. Acrylic paint does not fade, does not crack, durable. Because of these properties of its paint turns expensive.
  2. Polymer Latex gives the paint properties that are radically different from those of acrylics. Latex paint acquires water-repellent unusual properties, while the steam passes through it. The surface painted with such paint can not be protected from water. Price, respectively, even more.
  3. Polymer Silicate or liquid glass. Silicate paints do not trap air, allow steam to pass through, but poorly preserve walls from moisture. They are used in buildings with instability of groundwater under them.
  4. Polymer Silicone (Silicone resin). Paint with such a polymer combines the characteristics of two paints: acrylic and silicate combined. Its use is necessary in places such as a laboratory, hospital. It preserves the surface not only from external influences, but also does not allow mold and fungi to multiply on the walls. Accordingly, the price of silicone paint is even higher than the rest.

Types of water-based paint

The appearance of the paint can be matte or glossy. The smallest errors are visible under the glossy paint, so the surface must be carefully prepared, matte on the contrary hides them.

Advantages and disadvantages

Aesthetic appearance, lack of cracking, peeling, abrasion, burnout: all these advantages are in water-based paint. Surfaces with such a coating can breathe, as the paint is vapor-and breathable. Create a favorable climate indoors. The absence of solvents increases the explosion and fire safety during the production of these paints. The advantage is the economical consumption of water-based paint.

When purchasing paint, you should not pay attention to very cheap copies, the poor quality of paint will require the application of as many layers as possible. This will result in the price of the same quality paint.

If you choose the paint correctly, the disadvantages are almost eliminated. However, the disadvantage is that it can not paint the metal. And in other cases, the paint copes with a bang.
