The same hot-melt marking paint, the same road surface with different construction teams are likely to have very different marking quality. Some road markings have a 12-month warranty, and some are likely to have a 6-month warranty. Some will fall off within a few days. Although the quality of architectural coatings is critical, construction technology is crucial in the process of road marking construction.

Zhejiang Brothers Road Marking Co., Ltd. will take you to see the reasons for the peeling of the hot-melt marking paint: there is moisture on the ground, the temperature difference is large, the primer is not dry, the primer is not applied, the ground is not cleaned, and the old line The fusion is not stable.

1. Reason: There is water on the ground

External reason: After the ground is dry, the construction will be carried out

Dry or dry the engineering construction ground when necessary

Amplify the front fire of the silo

Reason: big temperature difference

2. Too low ground temperature will cause road markings to fall off

External reason: moderately increase the mold temperature

Increase the front fire of the silo

When necessary, pre-heat the construction ground of the project

Third, the reason: the primer does not dry

The primer (bright oil) is not sprayed evenly, the coating is too thick, the time interval is short, and the primer is not dry, which will cause the road markings to fall off

External principle: The primer is sprayed evenly, and the lines are drawn after drying.

Fourth, the reason: no coating agent

External principle: apply primer evenly

Fifth, the reason: the ground is not cleaned

The ground has dust, sand, oil stains, etc.

External treatment: cleaning and blowing the construction ground of the project

Soil and oil stains should be ground and polished first, and then the construction will be carried out after blowing clean.

Flow, reason: the integration with the old line is not stable

The primer is not applied, the primer is uneven, the primer does not dry, and the old thread is aging

External principle: first polish and polish the old lines, apply primer evenly, and draw lines after the primer dries.
