Dry acrylic paints and features of their use Dry wall paint - applications and varieties

Manufacturing companies today produce many types of paints and varnishes.

One of these is dry interior paints or pigments, which will be finely ground powders. Such dyes are used in order to add them to binders, to dye the mixture in a certain color.

After mixing with the base, a coloring composition will be obtained, which is ready for use. Pigments are made from mineral and artificial materials.

Advantages and disadvantages

Dry helmets have many important advantages, and here is a list of them with positive qualities:

  • Large selection of shades.
  • Lack of persistent and unpleasant odor.
  • Excellent indicators of hygroscopicity and vapor permeability.
  • Resistance to chemicals, including alkali.
  • Mixtures do not shallow.

  • Painted coating is not afraid of ultraviolet rays, does not fade.
  • Excellent hiding power, due to which paint consumption is very economical.

Please note that the spreading rate will largely be determined by the thickness of the applied layer, which will fully overlap the base base, for example, wood, concrete or other material.

The use of dry inks has certain difficulties that should be familiarized with in advance. Not all pigments are compatible with all base paint binders.

For example, chalk, lime must not be mixed with drying oil and oil. Such materials are allowed to be diluted only with plain water, as a result, mixtures are obtained that are similar to paint and varnish water-based products. It is recommended to dilute many types of dry paints with water.

Another nuance that is important to consider - dry-type paint is not allowed to be mixed with liquid paints and varnishes. If you mix them with each other, you will not be able to completely mix the resulting mixture, which is why the solution will not turn out to be completely homogeneous.

Inhomogeneous paints will not adhere well to the surface. Moreover, the amount of waste will increase, which means that the hiding power will decrease. Paint that has not been placed correctly will lead to streaks, streaks on the substrate, even if everything is painted by a professional painter.

To avoid lumps in the coloring mixture, pour dry pigments into water (or another thinner), and after a certain time stir the composition.

After mixing, it is recommended to filter the resulting mixture through a fine sieve.

Instead of a sieve, you can use a simple gauze, which will be folded several times. When the composition is filtered, it can be slowly poured into the paint. When the dissolved pigments in dry form are added to the base, it is important to stir the mixture thoroughly until the consistency is uniform.To get a certain shade of paint, it is important to add a little dry pigment with different shades, and this will be the difficulty. The staining process requires some skill on the part of the painter, and this procedure usually does not work out well right away.

It is much easier to use ready-made paints and varnishes, because they do not need to be prepared in advance.



There are many kinds of dry paint pigments and they are classified by shades.

White pigments

Dry paint for white walls is whitewash, chalk and lime. Chalk is sold in yellow, gray, or white and can be bought either ground or in bulk. Each variety is divided into three varieties, and finely ground chalk is used as a dye.

You can buy such material in pieces and grind it yourself. After that, water can be added to it, and the resulting solution is thoroughly mixed, and then passed through a sieve. The solution is poured into an infusion container. When the chalky particles settle, the water should be drained, and the top layer of the white sediment is taken out, dried and sieved, and then used as a dye.

Lime is one of the most popular paint substances.

It is diluted in water, mixed thoroughly until the consistency is uniform. When the liquid is milky, it can be applied to any surface. The most commonly used colorant is slaked lime, which can be mixed with suitable pigment additives. You can also add elements that will not change their shade after mixing with lime. For example, they add ocher, red lead oxide.

The paint is prepared in this proportion - 3/4 of water and 1/4 of lime. Whitewash is a finely ground powder mass. Dry pigments for paints are made by calcining metal components such as lead carbonate, titanium ore, lithopone, and zinc. Many types of white are used to create oil paints and varnishes and putty mixtures. Here are the indicators of covering power of different types of white per square meter:

Please note that if you need to make an oil putty or even putty, you should only use dry chalk, which should first be sieved through a fine sieve.

Yellow pigments

The most popular yellow pigments are ocher and crown. By the way, ocher is an extremely popular dye that has a yellow color and its shades, including golden. When ocher begins to ignite in a fire, it is called burnt.After calcining, ocher becomes reddish-brown in color, and such a substance has high resistance to aggressive environmental influences, and therefore it is used not for internal work, but also for external decoration. The spreading rate of ocher can be up to 0.

09 kg per square meter. Crowns are dry pigments made from lead and zinc. It is important to keep in mind that dry lead paints cannot be used for interior work, because they are toxic. Such pigments can be of different shades, lemon, orange and others. The spreading rate of crowns ranges from 0.

11 to 0. 19 kg per square meter.

Blue pigments

Azure and ultramarine can be distinguished among the blue pigment materials. The latter has the popular name "blue", and is used as an addition to lime and chalk whitewash. The purpose of the blue is to give the solution a blue tint.

The hiding power of paints for which blue is used is approximately 0.05 kg per square meter. Azure is a special substance that is used to create oil paints and enamels. Azure is not resistant to UV rays, and therefore, under the influence of the sun's rays, it begins to darken. Moreover, dyes made with glazes do not tolerate alkalis.

To enhance the color with azure, a little soot is often added, and the hiding power of the coloring mixture ranges from 10 to 60 grams per square meter.

Red powders

By the way, there are also dry acrylic paints. There are several red substances that are used to paint dry paint. These include iron, mummy, cinnabar and red lead. Red iron is a brick-colored paint.

The spreading rate of the product is 20 grams per square meter, while reddish orange lead has a reddish orange hue and its spreading rate is approximately 0.1 kg per square meter. Mummy is a red dye that comes in many different shades. The mummy does not have resistance to moisture, and it stains the surface with it on the street, then it can change its hue, and become dark red or even brown. The hiding power of such a paint is 30-60 grams per square meter.

Cinnabar has many different shades of red, and such a material has a high resistance to acids and alkalis, but it does not tolerate ultraviolet rays well, and can change its color under the influence of light. The spreading rate is 80-120 grams per square meter.

Green pigments

There are green dry pigments, these are chrome and lead steel. Chrome green or chromium oxide is a mixture of glaze and yellow crowns. Due to the change in the proportion of the glaze, different shades of powder can be obtained.

The spreading rate of the material is 40 grams per square meter. Lead greens are made by mixing blue and yellow substances, or rather crowns and azure.By choosing a certain proportion of materials, you can get different powder shades. Coverage of paint ranges from 30-70 grams per square meter.

Brown powders

Umber and burnt sienna give colors brown shades, and umber is a common colorant that has several shades of brown.

By firing the umber, a reddish brown color can be obtained. On average, the covering power of the substance is 40 grams per square meter. The characteristics of burnt sienna are similar to those of ocher. Siena is often used to paint wood when it is required to make the surface look like oak or ash. The disadvantage of such a material will be a low hiding power.

Black powders

Black is obtained by adding graphite, charcoal, manganese peroxide or soot to the paint. By the way, the latter is a black substance, which is a by-product of the combustion of petroleum products. Soot is a black powder, which is used as an additive for soap compositions, oil and glue dyes. Manganese peroxide is highly soluble in water. Wood graphite and charcoal are thoroughly ground and sieved before use.

The resulting powder is added to water, and any surfaces are painted with this mixture.

Metallic paints

Bronze, aluminum and zinc powder are used as coloring substances. Aluminum and bronze powders are used for application on metal surfaces, as well as for painting various products "like metal". The average spreading rate is 4 grams per square meter.

How to dilute paints

Painting with dry paints will not work without thinners.

Some types of coloring powders can be dissolved and diluted with any solution - soot, manganese peroxide, cinnabar, mummy, blue, umber, sienna, red lead, ocher, chromic oxide. Fine powder and lime are used only in aqueous solutions, and the rest of the components can be mixed with emulsion and adhesive liquids.

Tips for work

So, let's look at some useful recommendations:

  1. Dry acrylic paints and features of their use When using dry paints (pigments), you should monitor the temperature of the air, and it is best to keep the temperatures from +6 to +26 degrees.
  2. For the paint and varnish composition to be of high quality, it is imperative to sift the powder through a sieve. Due to fine grinding, the coloring mixture will be free of lumps.

  3. The viscosity of the mixture must be suitable for application by roller, brush or spray gun. Very liquid formulations will quickly spread in an extremely thin layer over the surface, and very thick paint lays down in a thick layer, and as a result, sags and streaks may appear.
  4. It is advisable to paint in 2-3 layers. After applying all layers, you should survive for several hours, a maximum of a day, for the surface to dry out.
  5. It is recommended to stir the coloring mixture with a drill or mixer.

    Manual stirring is quite laborious and does not provide the correct mixing quality.

  6. After dissolving the dry pigment in water, wait 15 minutes for the mixture to infuse. After a while, the solution is stirred again and applied to the surface.
  7. Before starting to paint, it is important to prepare the base, remove all irregularities, dirt, old paint layers, dust, grease stains, and it is also recommended to prime the surface.

No specific skill or knowledge is required to prepare a dye blend of their dry pigments.

Just a little practice and you get a wonderful paint that can be used at home to paint materials.
