4 Types of materials that are best used for Road Line Marking

Road Line markings can be made of a variety of materials. While the processing procedure is the same for all materials, you may consider a particular material for a given purpose. We summarize the essential road marking materials and discuss the requirements while applying them.

WATER-BASED

The most often used type of road marking paint is water-based. While line marking paint is not as durable as cold-applied plastics or thermoplastics, it is far less expensive and easier to apply. High-pressure piston pumps are the most often used equipment for water-based paints.

Water-based line marking paint is significantly more eco-friendly than other line marking materials. Additionally, water-based paints can be used over all different types of line marking, far less hazardous, dry rapidly, and usually require less sophisticated line marking equipment to apply than other types of paint.

Water-based paints should have a minimum shelf life of twelve months and be recoated every two years.

SOLVENT-BASED

Solvent-based line marking paint is not used often than water-based line-marking paint. It is less environmentally friendly than water-based paint and is only used in some instances when more durability is required or if the client requests solvent-based paint. Many have been phased out due to environmental concerns. The most frequently used equipment for solvent-based paints is high-pressure diaphragm pumps.

Solvent-based paints are often not used on bitumen or asphalt surfaces because they might damage the surface if not applied properly. It is often thinner than water-based paint and, when applied properly, will retain non-slip beads.  Solvent-based paints require solvents to clean the equipment, which frequently involves using extra personal protective equipment (PPE).

COLD APPLIED PLASTICS

Cold Applied Plastics (CAP) is a multi-component coating used in applications that demand high durability and extended life. It is easy to apply and cure and has a life expectancy of about five years in high-traffic areas. CAP needs highly specialized equipment and should only be used by competent and experienced personnel. It is crucial to avoid mixing the product in the machine once set. We have often seen expensive pumps rendered unusable due to mixed substances within.

CAP has excellent bead retention and may be recoated with water-based paint if necessary.

HOT THERMOPLASTIC

Hot thermoplastic is primarily used in environments with heavy wear, such as “Stop” and “Give Way” signs at junctions. It is available in a variety of forms. The two most common methods are “screed” (pellets or beads) poured into a melting kettle and “pre-form” symbols and lines set on the surface and heated to a particular melting point. Pre-form may also create corporate logos for reserved parking spots, giving commercial carparks a more professional appearance.

Although thermoplastic may be applied to almost any shape, using it in bulk needs specialized equipment. It is far more durable than paint, dries significantly thicker, and has superior bead retention.

Due to the high cost of the completed product, thermoplastic is frequently used on new roadwork to extend the life of existing lines.
