Means for painting the interior surfaces of the house

High quality pigments do not change color when moisturized and exposed to direct sunlight. For the preparation of dyes, special solvents are used, not water or oil. The technological characteristic of the coloring agent is the hiding power, that is, how much paint will go to one conventional unit of area, in this case, 1 m2.

Building paints come in a variety of colors

White pigments

Popular white dyes are made from lime dough, chalk or white. Air lime is used to paint work surfaces.

Lime milk is prepared as follows: lime is diluted with water 1: 3 or 1: 4. It is as liquid as a food product. Ordinary chalk is grayish or yellowish. Marked chalk MK1, MK2, MK3 are used for whitewashing – this is how the chipped variety is called.

The ground chalk is marked as MM1, MM2 and MM3. The lump chalk is broken up until it reaches the required quality. An excellent putty is obtained from the finest grind. When preparing a composition for whitewashing, the chalk solution is filtered through a double layer of gauze.

Whitewash

The coloring agent is obtained by fine grinding of the raw material – titanium ore, metallic zinc and lead. Zinc white is enough 100 g / m22, titanium 100 g / 150 m2, lead 200-300 g / m2.

Yellow pigments

These include crowns and ocher. Ocher is a yellow coloring agent. When heated, it darkens, acquiring a red-brown tint. This dye is called cherry or burnt ocher. It is enough 90 g / m22. Crowns come in a variety of shades, with tones ranging from lemon to orange. Spreading rate 100 g / m22.

Blue pigments

Ultramarine pigment is colloquially called blue, although it can also be greenish. The dye is used in lime and lime solutions. Actual calculation – 50 g / m2. Azure is both an independent shade and a color enhancement; it is added to the soot. Corroded by alkaline preparations. The product is added only to oil paint or enamel.

Red pigments

Red iron dye – red brick color, covering rate – 20 g / m22. Cinnabar has been known since ancient times. The product changes color when it comes into contact with the sun’s rays. The painted surface is acid-base harmful. Actual calculation – 100 g / m2.

Mulia. When applied, the product strikes with the brightness of the colors, but then the colors become dull or muted. Color palette – from delicate scarlet to dark red tones.

Construction paints

Green pigments

Lead greens are obtained by mixing different shades. Azure and yellow crown are usually combined. The subtlest and subtle shades are obtained through synthesis and trial and error. Actual calculation – 70 g / m2. Chromium green occurs in the same way as lead, only on the basis of chromium oxide. Actual paint calculation – 60-70 g / m2.

Brown pigments

Black pigments

Soot is a natural black paint, simple in origin. For production, they take the products of combustion of oil or natural gas. Dilute the product with soapy water or oil. Minimum spreading rate – 15 g / m22.

Metallic pigments

Sometimes, highly ground bronze and aluminum powders are used to paint surfaces. Hiding power of aluminum and golden bronze powder is 3-4 g / m22. Metallic powder is an excellent finishing material. Painting large surfaces is uneconomical, but light touches emphasize the individuality of the structure..

Before using this or that pigment, be sure to consider the compatibility rules. Chalk and lime are diluted exclusively with water. Alkali-resistant pigments include ultramarine, chromium oxide, red lead, mulia and ocher. This group also includes lemon, orange, scarlet and burgundy..
