Process of Application of Thermoplastic Paint:

Pre-Application Preparation

1. *Surface cleaning*: Clean the surface thoroughly to remove dirt, oil, and other contaminants.
2. *Surface preparation*: Prepare the surface by filling any cracks or potholes and ensuring it is dry and free of debris.
3. *Taping*: Apply tape to mask off areas that should not be painted, such as adjacent lanes or pedestrian crossings.

Application Process

1. *Heating*: Heat the thermoplastic paint to the recommended temperature (usually around 200°C) using a specialized heating machine.
2. *Application*: Apply the heated thermoplastic paint to the prepared surface using a specialized applicator or extruder.
3. *Spreading*: Spread the paint evenly to achieve the desired thickness and texture.
4. *Cooling*: Allow the paint to cool and harden before removing the tape and opening the road to traffic.

Post-Application Inspection

1. *Visual inspection*: Inspect the applied paint for any defects, such as uneven thickness or texture.
2. *Reflectivity testing*: Test the reflectivity of the paint to ensure it meets the required standards.
3. *Adhesion testing*: Test the adhesion of the paint to the surface to ensure it is secure and durable.

Maintenance

1. *Regular cleaning*: Regularly clean the painted surface to maintain its reflectivity and adhesion.
2. *Reapplication*: Reapply thermoplastic paint as needed to maintain the desired level of reflectivity and adhesion.
3. *Inspections*: Regularly inspect the painted surface for any signs of wear or damage.
Importance of Applying Primer Before Thermoplastic Paint:

Improved Adhesion

1. _Enhanced bonding_: Primer helps thermoplastic paint bond better to the surface, reducing the risk of peeling or flaking.
2. _Increased durability_: Primer extends the lifespan of thermoplastic paint by providing a strong bond between the paint and the surface.

Better Surface Preparation

1. _Fills pores and cracks_: Primer fills in pores and cracks on the surface, creating a smooth and even base for thermoplastic paint.
2. _Removes contaminants_: Primer helps remove contaminants, such as dirt, oil, and grease, that can interfere with paint adhesion.

Enhanced Paint Performance

1. _Improved reflectivity_: Primer can enhance the reflectivity of thermoplastic paint, making it more visible at night or in low-light conditions.
2. _Increased color retention_: Primer helps maintain the color and appearance of thermoplastic paint over time.

Reduced Maintenance

1. _Less frequent reapplication_: Primer helps extend the lifespan of thermoplastic paint, reducing the need for frequent reapplication.
2. _Easier cleaning_: Primer makes it easier to clean the surface, reducing the risk of damage or discoloration.

Types of Primers

1. _Epoxy-based primers_: Suitable for concrete and asphalt surfaces.
2. _Acrylic-based primers_: Suitable for concrete, asphalt, and metal surfaces.
3. _Polyurethane-based primers_: Suitable for concrete, asphalt, and wood surfaces.
