Oil paints are especially popular with experienced artists: artwork is often written by them in order to preserve the creation for centuries. In their composition is necessarily present drying oil - a film-forming substance based on vegetable oil.
Oil paints are of high quality only if they contain the highest varieties of drying oil. Relative to other varieties of
coloring substances, they have a low price. Their advantages do not end there: when applied, oil paints are converted into an environmentally friendly coating. Linseed linseed oil is very convenient for painting, because with its help the paints form a waterproof film. In order to apply paint to the canvas, you must make sure that the surface is cleaned of excess impurities and the primer is well dried. In the event that the uncured paint is on the skin, it can easily be removed with a piece of cloth dipped in vegetable oil. It is best to paint with gloves or use specially designed pastes.
It is important to remember that oil paints must be stored tightly closing the lid in dry and dark places: this way they will retain their properties longer. In order to dilute too thick paint, you need to use a special solvent, turpentine or white spirit. You can apply oil paints in any way: using any brush or roller. Most often, a small hard bristle brush is used for application.
At room temperature, the paints dry for at least a day: they usually retain their plasticity from two to three days. If the basis for the picture was a wood product, then after the paint hardens, evaporation from the surface of the base will not pass. When choosing paints, you need to clarify the composition, because it is similar in oil enamels, but in addition to drying oils, it also contains chemical film-forming substances. Enamels dry much faster than oil paints, so it is extremely difficult to use them for painting.
The optimum thickness of the paint layer is from 1 mm to 0.5 cm. You need to have sufficient drawing skill so that too thick a layer of paint does not spoil the work. Such a mistake will affect the longevity of the work, will lead to its rapid destruction. The process of painting is recommended to be limited by time: create until the oil paints on the canvas begin to lose their original consistency.
To avoid the formation of a dull layer on the surface, you should wait a period from the beginning of the hardening of the paints to their final hardening. Corrections are best made after the first coat of paint has completely dried. If the paints have only dried up, but have not hardened, the newly applied paint layer will dry dull, because the lower layer will draw oil from it, depriving the necessary binder. This can lead to cracks and unwanted voids: the simultaneous drying of the two layers will occur with different intensities.
Remember that the undeniable advantage of artistic oil paints is their resistance to moisture and various chemical interactions, so oil paintings may not change their appearance for years.
