Specifications include, but are not limited to: Provide paint free from foreign materials, such as dirt, sand, fibers from bags, or other material capable of clogging screens, valves, pumps, or other equipment used in a paint striping apparatus. Grind the paint pigment and properly disperse in the vehicle. The dispersions shall be of such nature that the pigment does not cake or thicken in the container and does not become granular or curdled. Any settlement of pigment in the paint shall be a thoroughly wetted, soft mass permitting the complete and easy vertical penetration of a paddle. Settled pigment shall be easily redispersed, with minimum resistance to the sideways manual motion of the paddle across the bottom of the container, to form a smooth uniform product of the proper consistency.
