How to Solve Bubbles in Road Markings?
All roads should be clean and dry during
the marking construction. Moisture is the most harmful factor in the adhesion
of paint and pavement. The amount of moisture in the ground is enough to affect
proper coating adhesion. Early morning dew and fog usually result in wet roads.
If there is too much moisture on the road surface, it usually leads to
blistering of the hot melt markings. Blisters will form as surface bubbles and
may not burst. If this happens, the marking construction should be stopped
until the road surface is dry. The only way to determine the presence of
moisture is to perform a test. There are many ways to test for moisture:
1. Place a 30cm square thin plexiglass plate (aluminum foil, etc.) on the road with tape, and seal the surrounding edges with tape. After 15 minutes, check the bottom of the board and the road surface. If the moisture is too much, do not hot melt marking construction.
2. Place a 45cm square tar paper on the
road surface and coat it with hot melt paint heated to 215 degrees Celsius.
Wait two minutes and pick up the tar paper. Check the underside. If there is
moisture, do not hot melt construction.
The ultimate purpose of installing and
maintaining road markings is to improve road safety; for this, high-quality raw
traffic safety materials are essential.
