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.View Less
1.1 This test method provides a procedure for the determination of the water absorption by a core of concrete taken from a surface treated with a water repellent.
1.2 The intended use of the water repellent coating is to reduce the amount of water that absorbs into the substrate.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
