Surface moisture conditions on concrete and construction materials are evaluated prior to the application of protective coatings, waterproofing systems, or repair materials. This assessment ensures that the substrate is adequately prepared and suitable for proper bonding, which is critical for achieving long-term material performance.

The test is commonly implemented during construction quality control and rehabilitation works to minimize risks such as poor adhesion, coating failure, or premature deterioration of repair systems. Early identification of excess moisture allows for corrective surface preparation, helping to ensure durable and reliable outcomes for reinforced concrete structures.
