Perchlorovinyl paints: what is it and what are they for?
What are perchlorovinyl paints? These are special coloring compounds that are distinguished by their special low cost and properties.
Since perchlorovinyl paints contain a certain amount of solvent that adversely affects human health, they should be used as carefully and carefully as possible. Given this, it is desirable to use such materials in non-residential premises with high-quality air ventilation. In addition, perchlorovinyl paints are characterized by a high level of flammability, which makes it impossible to use them in fire hazardous rooms.
The special composition of perchlorovinyl paints allows you to create coatings with a very saturated and bright color. This material is perfectly applied to brick, concrete and many other materials, providing them with aesthetic appeal and reliable protection. At the same time, perchlorovinyl paints are not recommended for use on surfaces that are actively in contact with sunlight. Otherwise, the coating will crack and deform.
The main purpose of perchlorovinyl paints is the facade decoration of buildings. They are remarkable first of all because they are able to keep their original color for eight years. But do not forget that such compounds are quite toxic, so it is generally undesirable to use them in the premises. Previously, however, perchlorovinyl paints were used everywhere.
You can apply perchlorovinyl paints for facade finishing only in the presence of certain temperature conditions, or rather a range from -20 ° C to +4 ° C. At a higher temperature, the compositions will evaporate intensively, which will negatively affect the well-being of both the painters and the people around them. If the air temperature is below -20 ° C, the paint will be too viscous and, as a result, inconvenient to use.
Particular attention when using perchlorovinyl paints should be given to the preparation of the treated surface, especially the primer. It must be coated with either a white primer or a special composition based on perchlorovinyl varnish and chalk.
It is better to apply perchlorovinyl paint in two layers. The second coat must be applied only after the first has completely dried. Painting can be done either with a roller or with an automatic spray gun.
Perchlorovinyl paint consumption is approximately 500 g per 1 m. After each use, the tool should be washed well.
