In 1924, Lester Wire, an engineer at the New York State Department of Transportation in the United States, first used a special paint to mark road lines. This paint has higher wear resistance and reflectivity and is considered to be the prototype of modern traffic paint.

As early as the 1950s, some states and cities in the United States began to realize the hazards of lead paint and took preliminary restrictive measures. For example, Chicago and New York City began to restrict the use of lead paint in residences in the late 1950s. However, these measures had limited impact nationwide.

There are significant differences in performance requirements between traffic paint and conventional paint. Traffic paint needs to cope with complex road environments and must have high wear resistance, weather resistance, fast drying and good adhesion. Ordinary paints are mainly used for interior and exterior walls of buildings, furniture and decorations, and their performance requirements are relatively low.

Although there are many benefits to using primer, in some cases you can choose not to use primer and directly spray white traffic paint. For example: construction time is tight, the road condition is good, and you can choose not to use primer in these cases for short-term use.

Main uses of white traffic paint: 1. Road boundary line, 2. Lane dividers, 3. Pedestrian crossing line, 4. Parking space markings, 5. Guidance arrows and symbols, 6. Airport runways and aprons.

The validity period of white traffic paint, that is, the time the marking remains clearly visible and effective, depends on many factors. Generally speaking, the validity period of white traffic paint is between 1 and 3 years, depending on the environment and maintenance.
