A few words about the paint.

Checking the ink viscosity. Oil paint compositions prepared from linseed oil and grated oil paint. Oil paints are ready to eat and gustotertye to be diluted varnish. By density of paint should be as liquid cream and drain freely from the shoulder blade. Viscosity of the paint or enamel is determined by the length of an accelerated way to drip drop vertically staged by the glass. For oily ink formulations length drip should be equal to 3,5-5 cm If the paint is stratified. If the paint bought before repair, their structure is modified somewhat: pigments with fillers settle down, and the connection pops up. Therefore, the paint before use to mix thoroughly. You can use the electric drill by inserting into it a specially prepared from a wire stirrer, by analogy with an electric mixer. If the paint in the banks has a different hue. If it is found that the paint of one color in a few banks have a different tint (this happens when ink of different parties), it is necessary to merge into one bowl and mix thoroughly. If paint thickens. Thickened paint diluted with turpentine, mineral spirits, linseed oil or varnish. For outdoor use as a diluent is used only natural varnish. Color matching by color. Pick up an oil paint color is easier than glue because it dries the color does not significantly change. Pick up the paint like in tone walls, you can use regular glass. After making a smear on the glass, it is applied to the wall. And then once we see the same color or not. Mixing paints. Ready-made paint color is not always suitable, because they have to prepare color by mixing several dyes. It is advisable not to mix gustotertye, and brought to a working thickness of paint. To get any shade each paint be diluted in a separate bowl, and only then drain. When cooking oil Kolerov used grated on drying oil pigments. As a basis for taking whiting (for light colors) or a paint such a tone that prevails in Kohler. When mixed with white and black turns gray, white and blue - blue, white and red - pink and other colors (darker or lighter), white and chrome yellow - lemon yellow, red and black - brown, blue and red - violet, blue and yellow - green. Homemade paint is filtered through a thick sieve. However, it should be borne in mind that some colors can not be mixed. For example, zinc oxide - yellow with barite, zinc yellow, lapis lazuli, cinnabar mercury, lead oxide - with cinnabar mercury, lithopone whitewash, barite and zinc yellow, ultramarine; whitewash Lee toponym - with whitewash zinc, the crown is yellow and green lead, chromium , cobalt violet, titanium oxide - with frosting; crowns yellow - with the mercury in cinnabar, barite yellow, zinc yellow - with cobalt blue, ultramarine, cobalt violet. With all the colors can be mixed with emerald green, chromium oxide, ocher, mummy, Mars yellow, umber, iron minium, malachite, bone burning, black grape and some others. Can I use paint? Choose paints for different surfaces, and depending on the quality and type of pigment. For example, lithopone whitewash is prohibited to use for outdoor work, as they darken from light, and white lead - for staining living quarters, because they contain toxic substances; yellow crowns are not allowed to paint on new plaster because of its neschelochestoykosti. Glossy or matte finish. By the nature of texture of the paint layer distinguishes glossy and matte oil colors. Surface stained with oil colorful compositions for protective and decorative purposes. In the case where the main purpose is protective coating compositions are used, forming a glossy film. In the formation of glossy films pigments sink into the thick paint coating over the pigment is a continuous layer of binder, a mirror reflects light. With high-quality decorative painting surfaces inside the building used as a rule, matte coating. These coatings soften the hues coloring makes it less noticeable defects in plaster, concrete, wood. Most often opaque coatings are obtained by reducing the amount of binder in the film and replacing it evaporating the solvent and introducing the compositions of matting additives - beeswax or synthetic wax dissolved in a solvent. Such coatings are beautiful, but their strength is low. In addition, film dries slowly, as formed on the surface wax film that prevents the evaporation of the solvent from its thickness and the ingress of atmospheric oxygen for the oxidation of oils. Matt can do yourself. Matt composition can be prepared most of the usual oil paints, adding them up to 0,5% soap and 10% white spirit. Soap solution is prepared as follows. Soap (40% case), cut into chips, is dissolved in a small amount of hot water (at 70 - 80 ° C). The resulting solution is mixed with mineral spirits and stirring is introduced into the oil paint. When you add soap strength ink film is somewhat reduced, so that it can not be washed and cleaned with a damp cloth. The walls are painted matte compositions, clear dry brush or with a vacuum cleaner. Checking the paint drying. Prior to the application of paint in case they need to check on vysyhaemost. And some paint, and their mixtures are allowed to dry completely for 48 hours. To test the stain a small area boards or plywood, shading the paint as much as possible in thin layers. If the paint dries longer usual time, add desiccant, per 1 kg of paint 20-30, the choice of instrument. Paint surfaces with oil formulations produce roller, brush or spray gun. When selecting a tool to keep in mind that small surface can be painted primaries brushes, wood products - windows, doors, trim - brushes, towels. For painting hard to reach places can be manufactured from a special holder for placing curved at a right angle tube, into which is inserted into the brush. If for any reason there is no brush, paint can with foam sponge clamped in holder for placing tin; worn sponge can be easily replaced by a new one.
