Clean the surface from dirt and dust. Prime concrete, plaster, stopper, brick, and building board surfaces. The surface to be painted must be dry. During the application and drying period the temperature of the ambient air, the surface and the paint shall be above +10 °C and the relative air humidity below 80 %. Drying is faster in low air humidity and/or above + 21 °C. Application will be easier if air is humidified and/or temperature is lowered in the working space. Ventilation after the painting will quicken the drying.
