Abstract
The invention relates to a ground surface marker and method for surface marking. It is known to apply surface markings, for example road markings, using paint. Many current road marking paints have a touch dry time from about five minutes to one hour, with full drying taking 24 hours or more, depending on the air temperature. The dry time of current paints can delay the opening of a road which may be costly because it increases the need for traffic control and can expose contractors to motoring hazards. If roads are opened prior to full drying of the paint, then the road markings may be compromised by contact with vehicle wheels. The invention aims to go at least some way toward addressing these problems by providing a ground surface marker comprising a paint applicator, a dispenser associated with reflectors, and a UV light source.
