Significance and Use
4.1 Researchers in the field of water repellent coatings have recognized the need for a standardized test for determining the performance of water repellents applied to structures in the field. Many coating manufacturer's supply warranties for their products based on maintaining a specific water repellency on concrete. This test method can be used to determine the effective water repellency of the coating by comparing its performance to a control uncoated specimen.
