Many countries in Southeast Asia (such as Indonesia, Thailand, and Vietnam) have high humidity all year round, with frequent rainfall and heavy dew. This high-humidity environment easily causes road marking paint to peel off, bubble, and lose adhesion, which not only affects the service life of road markings but also endangers traffic safety. This article will teach you how to choose road marking paint suitable for high-humidity areas in Southeast Asia, solving the common problems encountered in road marking construction.

The core requirement for road marking paint in high-humidity areas is strong water resistance and adhesion. Thermoplastic road marking paint with modified resin components has excellent water resistance, which can effectively prevent moisture from penetrating into the paint layer and causing peeling. In addition, water-based road marking paint with anti-mildew and anti-corrosion additives is also a good choice, as it is environmentally friendly and can adapt to the humid environment without fading or bubbling.

We also share key selection criteria: check the water resistance test report of the paint, choose products with high adhesion to asphalt/concrete, and avoid using solvent-based paint that is prone to moisture absorption. At the same time, we recommend practical construction tips, such as ensuring the road surface is dry before painting and choosing the right construction time (avoiding rainy days and high-humidity periods). This article will help you select durable road marking paint for high-humidity areas in Southeast Asia.
