Abstract: The testing apparatus facilitates the testing of surfaces for contaminants such as soluble salts prior to applying a protective coating. The testing apparatus includes an air-permeable water-resistant membrane, an overlay, and a test chamber. When assembled, the testing apparatus provides an easily removable testing apparatus that encloses a void into which a solvent may be injected to determine the level of contamination of the surface.
