Thermoplastic road markings are widely used on highways, urban roads, airports, industrial zones, and parking lots because of their excellent wear resistance, fast drying time, and high night-time visibility. However, many contractors and road authorities in Saudi Arabia face the same challenge: thermoplastic road markings begin to peel, crack, or detach from the pavement after a period of service.

Premature failure not only increases maintenance costs but also reduces road safety by lowering visibility, especially at night. Understanding the reasons behind peeling is the first step toward achieving longer-lasting and more reliable road markings.

In this article, we explain the most common causes of thermoplastic road marking failure in Saudi Arabia and provide practical solutions for contractors, distributors, and project owners.

Saudi Arabia has one of the world's harshest environments for road marking materials.

During summer, pavement temperatures can exceed 60°C, while highways are exposed to intense UV radiation, heavy truck traffic, wind-blown sand, and significant daily temperature changes. These demanding conditions place higher requirements on both road marking materials and construction quality.

Saudi road projects generally follow the Saudi Highway Code (SHC) and commonly reference internationally recognized standards such as EN 1871 for thermoplastic road marking materials. These standards emphasize important performance characteristics including:

Strong adhesion to the pavement

High wear resistance

Heat resistance

Good retroreflectivity for night driving

Even quality materials may fail prematurely if proper construction procedures are not followed.

Surface preparation is one of the most critical steps before application.

Dust, sand, loose particles, oil, or moisture remaining on the pavement prevent thermoplastic paint from bonding properly with the road surface.

This issue is particularly important in many regions of Saudi Arabia where sand and dust can quickly accumulate before construction.

Before applying thermoplastic paint, contractors should thoroughly clean the pavement using blowers, compressed air, or other suitable cleaning equipment.

Thermoplastic road marking paint must be heated to the manufacturer's recommended application temperature before use.

If the temperature is too low:

The material does not flow properly.

Adhesion becomes weak.

Air pockets may remain beneath the marking.

If the temperature is too high:

The resin may degrade.

Material performance can decrease.

Future cracking or peeling becomes more likely.

Maintaining proper heating temperature throughout the entire application process is essential for achieving long-term durability.

For concrete surfaces and certain aged asphalt pavements, primer significantly improves the bonding strength between the pavement and thermoplastic material.

Peeling often occurs when:

Primer is not applied.

Primer is applied unevenly.

Thermoplastic is applied before the primer has completely dried.

Selecting the correct primer and following recommended application procedures greatly improves adhesion.

Not every thermoplastic road marking paint is designed for extremely hot climates.

High-quality thermoplastic paint is manufactured using carefully selected resins, pigments, fillers, and properly graded glass beads to achieve stable performance under demanding environmental conditions.

When purchasing road marking materials for Saudi Arabia, buyers should evaluate product quality, consistency, and technical performance rather than focusing only on the lowest price.

Reliable materials can help reduce maintenance frequency and improve the overall life cycle of road markings.

Construction equipment directly affects marking quality.

Problems such as:

Unstable heating systems

Worn screed shoes

Uneven glass bead dispensing

Inconsistent marking thickness

can all reduce pavement adhesion and shorten service life.

Regular maintenance of thermoplastic preheaters, hand-push road marking machines, glass bead dispensers, and related equipment helps ensure consistent application quality.

Long-lasting road markings depend on both quality materials and proper construction practices.

Contractors are encouraged to:

Thoroughly clean and dry the pavement before application.

Maintain the correct heating and application temperature.

Use primer whenever required.

Select high-quality thermoplastic road marking paint and reflective glass beads suitable for local conditions.

Regularly inspect and maintain road marking equipment.

Check marking thickness, appearance, and glass bead distribution after application.

Following these best practices helps improve adhesion, wear resistance, and night-time visibility while reducing future maintenance costs.
