The coating shall be applied using airless spray equipment such as Wagner, Graco, or equivalent equipment at an ambient temperature not lower than -15°C and relative humidity not exceeding 85%. Manual application by brush or roller is also permitted. The material may be diluted with SPEKTRON FR-T solvent or solvent R-4 to achieve the required working viscosity, but the amount of solvent shall not exceed 5–7% by weight. The temperature of the structure surface shall be at least 3°C above the dew point. Application of the coating on wet surfaces, as well as surfaces with traces of frost, ice, or snow, is not permitted. The coating shall be applied in successive layers. The maximum applied layer thickness is 1500 μm. Equipment cleaning shall be carried out using xylene, toluene, R-4, or R-650 solvents.
