Oil paints are used for coloring of various surfaces. Drying up, the paint forms a film which protects a surface from humidity and rotting, and also from many other influences of environment on a surface. It is possible to wash the surfaces painted by oil paints with water, without being afraid of paint destruction.
New surfaces from wood have to be prepared carefully before coloring. It is necessary to cut down all knots and to cut off fibers, to drown more deeply the hats of nails. If you won't take care of mentioned factors then after coloring all these defects will act as hillocks on a surface. After cutting down knots, it is necessary to cover these places by plaster.
For the greatest quality of coloring, it is necessary to varnish a surface with oil. But it’s better simply to make primer coat with a liquid paint of the same color. It provides easier and more qualitative painting of a surface. For better adhesion of oil with a wooden surface, it needs to be warmed up and varnished several times. All small cracks and pores should be filled. It is necessary to wait time while earlier layer will dry up before you will varnish the next layer of oil. But in most cases varnishing is done just once.
