How to choose paint for repair?
How many the person distinguishes flowers? In a rainbow - only seven. And those consist of three main - red, yellow and blue. Orange, green and violet it is possible to receive, mixing in pairs primary colors. And if to mix at once three primary colors in different proportions? It is possible to receive both brown, and lilac, and purple, and in general any. Even such exotic, as “ color of a hip of the scared nymph “ (there is also such), and even yet not having own name.
The palette of modern paints contains tens of thousands of shades. You can choose one of them, and can receive color independently, mixing paints or adding special pigmentary pastes. This operation is called a kolerovaniye.
But be careful: the paints created on a different basis can be incompatible. Besides, sight can bring you. You will add, say, to white paint brown, wishing to receive “ coffee with " milk; and will leave pink or it is dirty - lilac. But even if you “ by eye “ received a desirable shade, in need of it it will practically not be possible to reproduce.
It is necessary to tint at the same time all volume of paint. And if it is not enough? Or will remain superfluous?
Therefore in modern conditions use of special tinting cars is expedient. They allow not only to receive the required amount of paint of the necessary color in a few minutes, but also to reproduce it subsequently. The choice of shades at the same time is almost not limited.
The leading global manufacturers developed tinting cards where code designation or number is appropriated to each shade for convenience of the consumer. To order the necessary paint, it is enough to specify the name of the catalog and a code of a shade.
Usually in the course only about two tens shades. However the powerful companies can offer tens of thousands of the most different paints thanks to well developed system of a kolerovaniye.
In the most perfect tinting systems of a proportion of components the computer sets that allows to achieve the inconceivable accuracy of shades.
What colors are most popular? For coloring of internal rooms on the first place pastel tone - beige, lime, apricot. And here for front works many prefer reserved yellow, light-brown and green. Though the traditional bleached huts decorated with kvitochka and pivnyka were not translated in Ukraine.
Paints are distinguished not only on color, but also on degree of luster of the formed coverings. Distinguish high-gloss, glossy, semi-gloss, semi-gloss, opaque and deep-opaque coverings.
Abroad degree of luster is expressed also number of reflection of light from the surface painted by this paint which is usually specified on a label near the name of material. Distinguish absolutely glossy (90/100), glossy (60/89), semi-gloss (30/59), semi-gloss (11/29), opaque (6/10) and absolutely opaque (0/5) paints.
Than glossy paints are good? They become soiled more difficultly and are easier washed, than opaque. However luster for certain will emphasize the slightest defects of a surface while the opaque covering will hide them. It is not excluded also that patches of light on a glossy surface will unpleasantly tire eyes.
That is why it is expedient to paint with glossy paint the most polluted places, what you touch more often - doors and window frames. For walls it is better to prefer semi-gloss and opaque coverings, and for a ceiling - absolutely opaque paints.
It is necessary to distinguish luster and gloss. Gloss of metal is imitated by the paints containing metal pigments, for example powder aluminum in the structure. On its basis the materials allowing to imitate silver, bronze, gold are developed.
But nevertheless metal pigments - yesterday. An eye will easily distinguish paint from the real metal. Original revolution among brilliant coverings was made by nacreous pigments. They consist of thinly crushed mica on which surface of particles with a chemical way the film from dioxide of the titan or other connection with high index of refraction is applied. A ray of light, having got to a trap between layers of mica and the refracting film, repeatedly is reflected and escapes outside in the form of dazzling shine which color depends on thickness of the refracting film just as it occurs in nacre and pearls.
Nature of gloss depends on the size of particles and changes from a lung silky to the bright pearl and sparkling metal. Varying thickness of a layer of the refracting film, receive extraordinary beautiful pigments of silvery, golden, red, blue, green or any other desirable color.]
