Latex paints

Latex

— one of the types of paints (see "Type") with the so-called water-dispersion composition.

All water-dispersion paints, in accordance with the name, are diluted with water when applied. At the same time, the actual “active substances” do not dissolve in water, but are in a state of emulsion — a suspension of tiny drops. Note that accidental contamination with such paint on hands, clothes, etc. can be easily removed by washing with water, or even simply by wiping with a damp cloth. But after drying (evaporation of water), such paint forms a dense film on the treated surface and becomes waterproof. In this case, the film is permeable to air, the treated surface “breathes”. In addition, among the general advantages of water-dispersion paints, one can note fire safety, non-toxicity, the almost complete absence of unpleasant odours, the possibility of using saturated colours, which, moreover, retain their original appearance for a long time, as well as suitability for use in conditions of high humidity.

This variety is most often an acrylic or acrylate paint (see the relevant paragraphs) with an additive in the form of latex. However, compositions are produced that do not contain acrylic polymers at all. Anyway, latex paints are considered high quality materials and cost accordingly. On the practical side, they are notable for their very high moisture resistance, versatility, the ability to tighten small cracks (up to 1 mm), as well as a good polymerization rate — the latter, in particular, facilitates the use of latex when painting ceilings. On the other hand, latex tolerates constant exposure to light less than pure acrylic, it does not "live" as long on surfaces exposed to direct sunlight.
