This stain is intended for use on exterior wood, either smoothly planed or roughly surfaced, where it is desired to permit the grain and texture of the wood surface to be seen more clearly than is possible with more highly pigmented stains such as TT-S-706, and where it is not necessary to provide the high degree of protection against wood weathering and retardation of dimensional changes obtainable with multiple coats of oil paint. House siding, fencing, and roadside signboards typify the intended use. On the other hand, this stain is not considered satisfactory for such millwork as frames, windows, and doors which need a high degree of protection against dimensional changes. It should not be used on surfaces that may soon be painted because the paraffin wax in the stain interferes with the drying and durability of the paint unless the stained surface has weathered for one or two years before paint is applied. This stain cannot be applied successfully to previously painted or varnished surfaces unless all previous coating has been removed to expose bare wood for staining.
