Our D.O.T. glass beads are used to create reflective markings for roads, highways, streets, curbs, concrete, parking lots, airports, driveways, pavement marking tape and more. Beads can either be applied to freshly painted surfaces or it can be used with a line striping dispenser to be applied with the paint. Beads can be applied to water based paint, oil based paint, alkyd coatings, hydrocarbon thermoplastic, and epoxies . Simply sprinkle the glass beads over the paint or coating while wet. Or follow the instructions on your pavement marking equipment. Let dry completely before use. Approximately 5 pounds of glass beads will coat 1 gallon of paint.
