Flood FLD447 CWF 1 Gal Clear Oil-Based wood finish. Revitalizes dried out, weather-beaten decks, restoring the rich, warm appearance of natural wood. CWF penetrates the wood to protect against moisture absorption and UV attack. New rough-sawn and planed wood should be allowed to weather 6 months or until it begins to turn a uniform light gray color before applying CWF. The original wood color will be restored after a period of exposure to sunlight and moisture.
