As different contractors and personnel search for the proper road paint to use, they should be aware of the differences of the paints available in the market. The effectiveness of the paint is dependent on its mixture and its suitability to the road surface it will be applied to. There are basically four major types of paint to consider.
- Oil or Solvent Based Paint
This is a mixture of different chemical solvents. In this type, the most crucial content would be the oil that comes from two general sources. It could be from food based materials such as vegetable oil which is commonly used for hobby paints (canvas oil painting). Or it could be petroleum based oil which is used for house paints and line stripping paints.
There are solvent based paints that are good to use specifically for streets, local roads, highways, and parking lots. This type of oil/solvent based traffic paint is quick to dry so it is fit to be used on concrete or asphalt surfaces. It also has great glass bead retention and is usually applied using a spray. Solvent based paint is also ideal in cold climates because it would not freeze. Unlike water based paint, it would not break down when the temperature drops.
- Water Based Paint
The water based paint is the choice of many environmental-friendly towns because it does not have any solvents that could be harmful to nature. However, more coats are needed in the application of this paint for better reflectivity. This is true especially in wet conditions like the rainy season. This paint is easy to apply because, similar to the solvent based paint, it is applied using a spray.
- Thermoplastic Paint
This type of paint has two different variations for application: hot or cold. Thermoplastic paint is not any ordinary paint. It usually has plastic contents that improve its durability once it is applied to the road surface. However, compared to the other paints for street markings, this one is more expensive.
The cold application thermoplastic paint is sprayed in a similar manner with a solvent based or water based paint. Hot applied thermoplastic paint, on the other hand, follows a more intricate process and requires specific tools. It could be applied using two general methods – torch and melter.
Some contractors think that they could apply the hot thermoplastic paint by screed, spray, or extrusion. In terms of durability, hot thermoplastic paint is more durable so it would last longer even after being exposed for a long time and through numerous road activities.
- Reflective Paint
Reflective paints are really on the expensive range. They are specifically made through the addition of glass beads right after applying the paint. This process results in its excellent reflectivity at night. Usually, though, it is used for striping road lines or for informational road markings.
Experts are still continuing to make breakthroughs in improving the type of road paints that could be used for longer periods of time. It is better to be familiar with each type so that choosing the right paint would be easier. To find other ideas, there is road paint from Ennis Flint for each of the following functions. Every paint type is also made to suit different asphalt and concrete roads.
