1.1 A newly applied traffic paint film may be exposed to hard rain shortly after application. This practice was designed to simulate that condition and covers determination of the water wash-off resistance of an applied traffic paint film under controlled conditions. This test can be used to compare conventional and fast-dry traffic paints and the binders used in them for their relative ability to withstand heavy rain soon after application on roadway surfaces.
