After waterborne traffic paints are applied to a road, airstrip, or parking lot pavement, it is important that the paint films be sufficiently hardened, coalesced, or cured so they will not be removed by rain. This practice can be used to determine the relative performance of binders and other components within traffic paint for their effect on the water-wash off resistance of the coating. Some key elements of the coating that may affect water-wash-off performance are the quality and type of latex binder, the dry time of the coating (often conducted by Test Method D 711), pigment volume concentration (PVC), and the relative water sensitivity of additives (for example, pigment dispersants, and surfactants) in the coating.

1.1 A traffic paint film freshly applied to a roadway, air strip, or parking lot may be exposed to rain of varying intensities shortly after application. This practice was designed to determine the relative water wash-off resistance of an applied traffic paint film under controlled laboratory conditions using a water faucet to simulate a heavy rain. This laboratory practice can also be used to compare conventional and fast-dry waterborne traffic paints and the effects of binders and other components in traffic for their relative ability to withstand a heavy rain soon after application.
