ABSTRACT:
During the laying of a marking line with the aid of at least one paint spray gun (2), profile particles (5) are introduced by means of a profile particle dispenser (4) into the marking composition (3) and thereby enveloped all round by the latter. The dimension of the profile particles (5), which are preferably reflective beads, is greater than the layer thickness of the bare painted line, so that profile elevations are formed. Subsequently, reflective beads (8) which also adhere to the profile elevations are scattered onto this profiled painted line (6), which beads thus ensure a good night visibility in wet conditions and when a water film is present, from which they project. The profile particles (5) can either be directly introduced into the jet of paints emerging from the paint spray gun (2) or, subsequent to the application of a painted line, be scattered thereon and then completely covered with marking composition by means of renewed spraying of a thin film of paint.
