Common problems with hot-melt road marking coatings, 99% of construction teams have stepped on these pits

In the field of road marking construction, hot-melt marking coatings are widely used due to their excellent durability and cost-effectiveness. However, even experienced construction teams often encounter some tricky problems. As a professional marking paint supplier with 30 years of experience in the industry, TOP ROAD Transportation Technology Co., Ltd. has witnessed countless construction cases. Today, we will take stock of the “pitfalls” that construction teams are prone to step on, and help you avoid unnecessary losses.

The first major pitfall: improper boiling of paint

Many construction teams often overlook the importance of boiling hot melt coatings. Excessive cooking time can lead to yellowing and decreased performance of the coating; Improper control of the temperature can affect the fluidity of the coating. A more common problem is that the remaining paint in the kettle is not properly disposed of after construction interruption, resulting in problems such as clumping and sedimentation during construction the next day. The TOP ROAD technical team suggests that correct insulation measures should be taken during construction interruptions, and an appropriate amount of new material should be added to maintain the activity of the coating.

The second biggest pitfall: neglecting road surface pretreatment

Directly marking lines to save time is a common problem among many construction teams. Little did they know that newly laid asphalt pavement is not sufficiently stable, cement pavement is not thoroughly cleaned, and wet pavement is not dried, all of which can lead to insufficient adhesion of the markings, resulting in problems such as detachment and peeling in the later stage. TOP ROAD professional engineers remind that road surface inspection and pre-treatment must be done before construction, and special primer should be used if necessary. This is a key step to ensure the quality of the marking.

The third major pit: One size fits all construction parameters

Many construction teams are accustomed to using the same set of parameters to handle all working conditions, which is a significant misconception. Environmental temperature, road conditions, and differences in coating batches can all affect the construction effect. Experienced construction personnel will adjust parameters such as material temperature and construction speed according to the actual situation. TOP ROAD provides detailed technical parameters and construction guidance for each batch of paint, helping construction teams avoid this common problem.

The fourth major pitfall: neglecting post maintenance

Another common mistake is to ‘open the road after drawing the line’. Hot melt marking requires an appropriate curing time, as early opening to traffic can cause deformation of the marking and detachment of glass beads. Especially in low-temperature environments, it is necessary to extend the curing time. TOP ROAD’s seasonal formula products can provide solutions for different climate conditions.
