Indoor and outdoor
Indoor vs Outdoor Hazard Markings
Outdoor hazard markings use traffic paint, and indoor markings use two-part epoxy or polyurea floor coatings. The surface, the traffic and the season decide which one lasts.
Outside, we spray waterborne acrylic traffic paint from May 1 to October 15, when Canada's 150 g/L VOC cap applies, and can use solvent-based alkyd in the cooler shoulder months. Expect 12 to 24 months before a repaint, or 3 to 6 years if we use preformed thermoplastic for the busiest hatched zones.
Inside, forklift tires grind paint off concrete in weeks, so we use epoxy lines that last 3 to 5 years under lift truck traffic. Indoor work runs year-round as long as the slab is above 10 C and dry.
Floor markings for aisles and racking are covered on our warehouse floor line painting service, and hazard stripes on columns and ramps underground are part of our parking garage line painting service.
