Coating is the critical step among marking construction, sealcoating equipment and please pay more stict attention to its operation procedures. Coating procedures and precautions: 1) Check pavement marking equipment and inspect the construction equipment carefully and assure that they are in good condition. Please do pre-marking, and check pavement striping machines the color, thickness, width, volume and glass beads spread volume. if necessary, adjust the parameters and asphalt striping machine. 2) Coating should be start after the primer drying thoroughly. Or, the solvent will penetrate the unhardened paint film, resulting in solvent bubbles, field striping machine and marking contamination. 3) To ensure the visibility of markings at night, please spread glass beads when coating construction. It is demonstrated that half of the diameter of field marking equipment glass beads embedded in coating that the reflect effect is the best. But we should know that the glass bead will be buried in the coating if line marking equipment the paint temperature is high, while the glass beads spreading speed is fast ,and the glass beads can not adhered to coating firmly and is easy to come off if the paint temperature is low, while line markers glass beads spreading speed is slow, for at that time the coating is almost solidified, which will affect the whole reflect effect. Glass beads should be spreaded uniformly, generally speaking, 0.3~0.5kg on square meter is proper. If line striping equipment the glass bead is too excessive, it will make the markings' color bad and cause uneven visual effect, and is easy for dust to stick on it and effect the visibility.
