GB/T 6753.2-1986 "Test for surface drying of coatings—Ballotini method" specifies a method for determining the surface drying time of coatings using the small glass ball (ballotini) method, which is applicable to various types of coatings. The method involves sprinkling small glass balls of a specified size onto a wet paint film after application and observing whether the balls adhere to or leave marks on the film to assess its surface drying state. The test requires standard small glass balls, a film applicator, a timer, and test panels. The procedure is simple and provides a reference for controlling the intervals between coating applications.
