Transparent and semitransparent stains may last from three to four years. These finishes contain pigments which protect the wood from the degrading effects of solar radiation. The best products contain water repellents, mildewcides and ultraviolet light blockers or absorbers. When selecting a pigmented stain, CRA recommends testing finishes on a small area to be sure the desired color effect is achieved.
Transparent stains contain less pigment than semitransparent stains and provide a more natural look.
These finishes can be used on decks, fences, siding or other exterior projects.
