Description of Hot Melt Paint
Hot melt paint is a type of thermoplastic coating material.
It is usually in a solid state at room temperature. When heated to
a certain temperature, it melts into a liquid with good fluidity,
which can be easily applied to various surfaces such as roads and
metal. As it cools down, it quickly solidifies again and forms a
durable, hard - wearing, and often brightly - colored film. This
kind of paint is widely used for traffic markings on roads, parking
lots, and also for industrial equipment marking and other
applications due to its excellent abrasion resistance and fast -
drying characteristics after application.
Detailed Process of Hot Melt Road Line Paint Construction
1. Prepare the Surface
- Cleaning: Ensure the surface is free of dirt, grease, oil, dust, and loose
debris.
- Repair: Fix cracks or uneven areas to create a smooth surface.
- Drying: The surface must be dry to ensure proper adhesion
2. Mark the Layout
- Use chalk, tapes, or temporary markers to outline the areas to be
painted (lines, symbols, or shapes).
- Verify measurements against specifications or local standards.
3. Heat the Thermoplastic Paint
- Use a melting kettle or thermoplastic preheater to melt the paint.
- Heat to the recommended temperature, typically 180–220°C (356–428°F).
- Avoid overheating, as it may degrade the paint and affect quality.
- Stir continuously to ensure uniform consistency.
4. Primer Application (if required)
- Apply a primer to the surface if recommended by the manufacturer.
- This is especially needed for non-porous surfaces like concrete or
asphalt.
- Allow the primer to dry before applying the paint.
5. Apply the Paint
- Screed Method: Use a screed box to create uniform thickness for road markings.
- Spray Method: Use a spray machine for even application on large or irregular
areas.
- Extrusion Method: For thicker, raised markings.
- Hand Application: For small areas or repairs, manually pour and spread the molten
paint.
- Preformed Thermoplastic: Lay pre-cut sheets or symbols on the surface and heat with a
propane torch until adhered.
6. Check and Correct
After the coating is completed, check and correct the line shape,
check the spread of glass beads, etc.
After confirming that it is correct, the construction site will be
cleaned up.
After the line is dried and hardened, the relevant construction
equipment can be transferred, the safety facilities can be
dismantled, and the traffic can be opened.

Advantages of Hot Melt Paint
- High Durability
It has excellent abrasion - resistance and can withstand repeated
friction and pressure from vehicles and pedestrians. It can
maintain a good appearance for a long time even in areas with heavy
traffic. For example, on the lane markings of a highway, it's not
easy to wear out even after a large number of vehicles have passed
over it.
- Quick - drying
It dries fast and can be put into use shortly after application.
This is very important in road construction as it can reduce the
impact on traffic.
Disadvantages of Hot melt Paint
- High - temperature Dependence for Application
It usually requires high - temperature equipment for application.
Special heating tools are needed to melt the paint before use. If
the temperature is not well - controlled during the heating
process, it may affect the quality of the paint, such as its
fluidity and adhesion.
- Difficult to Remove or Modify
Once applied and solidified, it's quite difficult to remove or
modify. If there is a need to change road markings or remove the
paint from a surface, it often requires special tools and complex
procedures. Compared with some water - based paints, hot - melt
paint is more stubborn in this regard.
How to Select Suitable Thermoplastic Paint
Choosing the right thermoplastic paint for road marking depends on
several factors to ensure durability, visibility, and compliance
with standards. Here are the key considerations:
1. Application Environment
- Climate Conditions: Consider weather conditions such as temperature, humidity, and
rainfall. Some paints are specifically formulated for extreme
temperatures or high-moisture areas.
- Traffic Volume: High-traffic areas require more durable paints with better wear
resistance.
- Surface Type: Ensure compatibility with the road surface material (e.g.,
asphalt or concrete).
2. Performance Requirements
- Durability: Select a paint with high resistance to wear and tear, especially
for heavy-traffic roads.
- Reflectivity: Opt for paints that allow for the embedding of glass beads to
enhance nighttime visibility.
- Skid Resistance: For safety, especially in wet conditions, choose paints with
anti-skid properties.
3. Compliance with Standards
- Check if the paint complies with local regulations and standards
for road markings, such as color, thickness, and reflectivity.
4. Application Method
- Some paints are designed for specific application methods, such as
spray, screed, or extrusion. Choose paint compatible with your
equipment.
5. Color and Visibility
- Select colors with high contrast to the road surface (e.g., white,
yellow) and UV-stable pigments to prevent fading.
6. Drying Time
- In high-traffic areas, choose a fast-drying formula to minimize
disruption.
7. Cost Efficiency
- Balance initial cost with long-term performance. High-quality
thermoplastic paint might have a higher upfront cost but longer
durability, reducing maintenance expenses.
8. Supplier Reliability
- Purchase from reputable manufacturers or suppliers who provide
quality assurance, technical support, and consistent product
performance.
By considering these factors, you can choose thermoplastic paint
that meets your project’s specific needs and ensures long-lasting,
high-quality road markings.
