The last type of painting is used for final finishing of already painted surfaces, and in addition to varnishing it also includes polishing of the indicated surfaces. The types of colors for each room are set by the project, and the painting works themselves are carried out according to samples approved by technical supervision. Painting compositions and semi-finished products for painting in the form of concentrates, pastes, briquettes and dry mixes are prepared in a mechanized way in factories or in procurement workshops. At the work site, it is only allowed to bring the compositions to the working viscosity, which provides surface coverage without draining of the compositions and without noticeable traces of the brush.

Before painting, glazing is performed, the heating system is installed and started. Interior finishing is carried out at a room temperature not lower than +10 ° C and a relative humidity of not more than 70%.
