For the rational decision of colors on the different building objects it is recommended to use optimal colors to create the best climate at industrial enterprises. For this purpose the appropriate building codes are developed. Building constructions in the industrial enterprises, which are applied fire-retardant paint, also painted in the appropriate color with tinting paste, or applying the finishing coat with that color. It is shown, that the introduction of tinting paste in the fire-retardant paint as overcoating of the fire-retardant paint leads to chaotic effect on height of foam of the intumescing coatings. The conclusions about invalidity of coloring with the fire-retardant paints in saturated tones used tinting paste without preliminary testing on the fire retardant efficiency are made. Similar conclusions are applied to the paint systems for an intumescing fire protective coatings using surface finishing.
