This standard evaluates the brush resistance of latex paints through a standardized brushing procedure to help compare the performance of different coatings in practical applications. Increased brush resistance may result in a thicker film, improving durability and covering, but may also affect the ease of painting. This method provides a more reliable and accurate alternative to traditional methods for evaluating brushing performance. SI units are standard units and values in parentheses are for reference only. It is up to the user to determine the applicable safety measures.
