This guide covers the selection and use of procedures for testing exterior wood stains. This includes both water borne and solvent borne semitransparent and opaque stains. The different conditions that affect coatings are presented in details. The balance of properties must be considered when establishing the requirements and selecting the tests. The different test methods in determining the liquid coating properties are enumerated and discussed. The different methods in determining the coating application and film formation are presented and discussed in details. The different test methods of determining the appearance of dry films are presented. The different test method of determining the dry coating properties are presented in details. The different test methods and practices in performing the chemical analysis of exterior woods are presented in details. Although many of the recommended test methods attempt to simulate conditions under which coatings are applied and used, it is not possible to duplicate accurately all possible conditions. Testing materials, including appropriate controls, under field conditions is recommended for the final evaluation of suitability.
