Significance and Use
4.1 Laboratory measurement of application properties of architectural coatings generally employ a blade-type applicators that lay down films of highly uniform thickness. Applicators, such as brushes and rollers, typically apply films that lack uniformity due to variations in rheology, film build, flow and leveling properties resulting in the practical hiding of most paints being less than that measured on films applied with a blade-type applicator. This guide provides an indication of the actual application properties of the paint, as applied by a contractor or consumer.
1.2 Because both the application and panel evaluation are subjective, this guide should be used only for comparative testing within one laboratory using one operator for each set of applications, as the ratings assigned by different laboratories may not agree.
