Smoothing cycles are also referred to as "thick film systems". The floor obtained is colored and the thicknesses usually vary from a minimum of 0.3 mm to 1 mm (in particular cases they reach 1.5 mm). The different phases that make up the structure cycle: the application of the primer (by roll or by smoothing), the body of the covering (by smoothing) and the finish (by roll). The smoothing application is performed with a smooth-blade spatula (also called doctor blade).
