Limestones
This type of mineral paint is usually used for outdoor use. The base of this paint is slaked lime, to which table salt and alum can be added to increase the durability of the finished coating. Alkali-resistant substances are used as pigments, such as soot, umber, red lead, mummy, ochre, sienna, etc. These pigments must be used in a paste-like state; their consistency should resemble sour cream. These substances are pre-soaked in water and added to the mineral paint in this state.

The color of such mineral paint can be "bleached" or pastel. The degree of hiding power depends on the consistency of the dye and the number of layers applied. The hiding power index is the ability of the paint to hide the material being painted. Hiding power is determined by the volume of the paint mixture that is spent on one square meter of surface.

Although such mineral paint can be made by hand and will qatar mobile database cost much, it is very short-lived, its service life is 1-2 years. It is easily washed off the surface, but also quickly applied again. The service life of such a coating can be extended to 4 years, subject to the following painting technology:

apply a layer of primer using a brush or a wide brush. After the primer has dried, the liquid lime paint must be rubbed into the surface with force so that all pores and cracks are reliably filled;
After the first layer has dried, it is necessary to apply the second, main layer using a spray gun or brush.
Cement compositions
To paint brick, concrete, plastered and stone surfaces, use cement mineral paint. This dye is made from white cement, calcium chloride, which accelerates the setting process, and water-repellent substances and slaked lime are added. Water-repellent ingredients increase the coating's water resistance. Cement compositions are made in almost the same way as lime mixtures, using alkali-resistant substances as pigments, which are pre-soaked in water.
