Paints for marking roads can be waterborne or solvent-based, depending on the manufacturer. Uses for road marking paint include:
- Scratching the surface of roads and tunnels.
- Private and public parking lots.
- Determining the location of a pedestrian crossing.
- Marking the roadside in various design locations.
The unique properties of these colors make their use in road marking projects justifiable and even superior to standard colors. There are some common characteristics among the road marking paint available on the market that make them ideal for use in various environmental conditions, including harsh ones.
You must ensure that the road surface is free of dirt, oil, or dust before you begin marking it. Apply one or two coats of road paint once the road has been thoroughly cleaned.
Types of Road Marking Paints
At least two components are required for solvent-based painting: one for the paint and a hardener. Adding the hardener causes a chemical reaction that sets the color permanently. For this reason, solvent-based paints are typically more durable than water-based paints.
Solid polymer particles are present in waterborne paints. Inorganic compounds may also be present. The particles quickly absorb water. Waterborne road paints commonly employ ion-exchange particles. The paint on the road can dry more rapidly thanks to these particles. The solvents and water in the paint evaporate after application. A single layer of paint is formed by combining the fine particles.
Choosing the Right Road Marking Paint for Your Project
Colors, lines, and symbols used in a standardized system can change depending on federal and state guidelines. Still, the underlying goal remains the same – protecting the users (e.g., drivers, bikers, and walkers).
There are various road marking paints on the market, each of which has its own set of advantages and disadvantages. We’ll go over the different types of paint and how to pick the best one for your road marking project in the sections below.
Road Marking Paint Selection Factors
For road marking projects, there are several considerations to keep in mind, including:
• Local, state, and federal laws. Many countries and states have different rules on how road markings should be applied, with some states enforcing stricter regulations than federal authorities. At the same time, some states (e.g., California) demand paints with even smaller quantities of VOC, such as those found in the European Union.
•. According to the location of the markings, the guidelines for road markings can also be different (e.g., road vs. parking lot vs. airport runway). When it comes to paints, high-traffic areas (e.g., parking lots) need long-lasting paints, while high-visibility locations (e.g., airport runways) need a color that can be seen clearly.
• Water-based paints are generally unsuitable for environments with high moisture content. In contrast, colors with high-quality pigments are ideal for environments with a high concentration of UV radiation.
