The working surface must be dry and clean. Remnants of old coatings should be removed. Apply one coat of L'acrilico primer to the surface and let dry for 2 hours, then apply two coats of decorative paint with an interval of 4-6 hours between coats. After applying a second coat, leave to dry for 24 hours (at a temperature of + 20 ° C and a relative humidity of 65%).
