GB/T 13477.5-2002 "Test Methods for Building Sealants Part 5: Determination of Tack-Free Time" specifies the method for determining the tack-free time of building sealants. This method involves spreading a specified amount of sealant onto a substrate and, under standard conditions, using the finger-touch method (such as lightly touching the sealant surface with a finger) or specialized instruments to measure the time required for the surface to lose its tackiness and form a dry skin. This parameter is crucial for controlling construction processes.
