Special feature of oil paint
Specialists divide oil paints into two large types - thickened ones, which require preliminary dilution with linseed oil, and also ready for use, which can be immediately applied to the surface.
They include pigments that impart a certain color, and synthetic or natural varnish. Despite the name, oil paints are made from drying oil, and it, in turn, is extracted from vegetable oils.
As a rule, in an apartment the paint is used for finishing bathrooms, kitchens. The painted surface is easy to clean, remains perfectly protected not only from mechanical damage, but also from drying and rotting process, when it comes to wooden surfaces treated with paint.
Use oil paint carefully, avoiding contact with human skin. If the droplets hit the walls, they can be quickly removed with a solvent. When working it is important to ensure a constant supply of fresh air, the composition has a very specific smell, which can irritate the person's mucous membrane.
In order to properly dilute the paint, often not only linseed oil, but also solvents such as turpentine, acetone. If you choose this option, you need to remember the main rule: the percentage of solvent can not exceed 5% of the total mass of the paint.
To correctly calculate the amount of liquid for diluting the paint powder, you need to know the specific gravity of the oil paint, each type has its own, you can see the exact data in special tables that are on the Internet.
Getting ready to work correctly
In order for the repair to go well, you must first prepare the surface for applying the composition. The quality of the coating directly depends on the training. So, the surface must be previously cleaned, using special tools, cleaned of dust and dirt, try not to allow small particles of debris to come directly into the paint, they can adversely affect the texture of the painted element.
A layer of old paint must be removed completely, removing it not only with a spatula, but also with solvents( if necessary).They will also help get rid of fatty sludge. If the surface initially remains uneven, you can correct the situation with the help of putty and special tools.
Practice shows that working with oil paints does not tolerate negligence, only the correctly diluted composition applied by paint brushes will lie flat on the prepared surface. The remaining dirt can cause rapid destruction of the layer.
Several tricks for the home master
Special additives, which can be considered as construction tricks, will help to get a matte surface. To do this, oil soap is added to the oil paint with a calculation of 40%, i.e. 1 piece per 3 liters of paint.
That the paint in the bank does not dry out, it can be covered with a thin layer of ordinary sunflower oil. Surface treatment is carried out by special brushes, their safety will be provided by a glass of water, into which it is necessary to lower the tool after each stroke.
To understand how to properly use oil paints, it is enough to recall its composition. Oils react sensitively to air, quickly dry up, old paints can not be mixed with each other, otherwise there is a risk of getting a compound that will not dry up and turn into a viscous mass.
In the process of work, it is important to ensure that on the surface of the cans or buckets into which the brush is dipped, no film is formed. Experts advise to use a normal kapron stocking, which reliably protects the brush from unnecessary impurities. It is enough to "drown" the material in the paint and use the composition that has leaked through the mesh.
As a rule, the layer dries out after a week in summer, in winter the surface may take a little longer. Modern materials can dry in 2-3 days, this information is indicated on the bank.
