Specifies a procedure for measurement of mudcracking occurring in heavy build-up of air-dried latex paint.

This Standard describes a method for determining the resistance to mudcracking of an air-dried latex paint film, typically applied at 30-50 mm dry film thickness. It provides a method for evaluating the tendency of paint coatings to crack in locations where there has been an excessive build-up of paint, e.g. in the corner of a room, particularly at ceilings and cornices. This occurs most commonly with flat paints.
