This guide covers the selection and use of procedures for testing exterior wood stains and clear water repellents. This includes both water borne and solvent borne semitransparent and opaque stains and clear water repellents. The properties that can be examined or, in some cases, the relevant test procedures are listed in 2.1 and 2.2.
NOTE 1-The term "opaque stain" is defined as a pigmented composition intended for use on wooden surfaces to produce a uniform finish that obscures the grain and color of the wood, but not its surface texture; also called solid color or solid hide.
NOTE 2-The term "semitransparent" is defined as a pigmented composition intended for use on wooden surfaces to produce a uniform finish that does not fully obscure the grain or the texture of the wood.
NOTE 3-The term "clear" is defined as a transparent composition intended for use on wooden surfaces to produce a uniform finish that does not obscure the grain or texture of the wood.
Discussion-When applied to woods that differ in color, there is a color difference between stained substrates.
