Common misconceptions about using hot-melt line marking machines: Many customers unfamiliar with hot-melt line marking machines often mistakenly believe that it's the same as room-temperature cold spraying—that all you need is a hot-melt line marking machine. However, the reality is that hot-melt line marking is far more complex than room-temperature line marking.

（1）Road cleaning：Special personnel were assigned to clean the road surface to ensure it was clean and free of noticeable dust.

（2）Surveying and setting out：With the road surface clean, mark the points according to the design drawings, then use white latex material to mark the waterline of the road edge. After checking that everything is correct, proceed with the marking work.

（3）Marking：      

a: Add the hot-melt paint to the hot-melt kettle and heat evenly to the appropriate temperature.
b: Apply a road-specific primer evenly to one side of the prepared waterline to ensure better adhesion between the road surface and the markings, and to prevent groundwater evaporation, thus avoiding marking detachment after construction.
c: Load the hot-melt paint, melted to a workable state, into a push-type construction vehicle, and add an appropriate amount of glass beads to the vehicle bed.
d: Adjust the flow rate, and begin construction when the primer has dried to the appropriate degree. Use the waterline as a base during construction to ensure quality.
e: The coating thickness for lane edge lines, lane dividers, directional arrows, road center lines, and warning markings is 1.5-2.0 mm; the thickness for speed reduction markings is 5 mm. The glass beads should be evenly distributed on the surface. The drawn markings should have good visibility, consistent width, equal spacing, flush edges, good reflectivity, and a firm bond with the road surface.         

Hot melt line marking construction techniques for line marking machines
Because hot-melt marking machines require heating the powdered marking paint to a high temperature of 180-200 degrees Celsius to melt it into a liquid before use, small hot-melt marking machines typically use separate marking devices and heating equipment for melting the paint for safety reasons. This avoids unnecessary burns and significantly improves melting efficiency. Generally, newly established marking teams need the following hot-melt marking equipment: hydraulic double-cylinder hot-melt autoclave, hand-push hot-melt marking machine, hand-push hot-melt zebra crossing machine, hand-push pre-marking machine, etc.       

Cleaning：During construction, lines are marked and cleaned simultaneously to ensure no littering, spilling, dripping, or leakage, and no pollution or equipment leaks of oil or water. The construction team cleans the road surface within a certain distance after marking the lines, keeping the surface clean, free from pollution and damage.

Hand-push type hot melt road marking machine is one of the earliest hot melt road marking machines to be used due to its advantages such as simple structure, small size, light weight, easy transport, easy operation and maintenance. It has construction flexibility and equipment durability.
