"I applied this deck stain to an old deck, stairway, and dock in April 2011. Some of the boards were extremely weathered, while others were brand new replacement boards. The stain made all of the boards look the same. Fifteen months, several high tides, and one hurricane later, everything still looks the same as the day I applied it. We live along the east coast, and occasionally the dock is under water. It still looks fabulous. We just built a wood fence, and will be applying this stain to it as well."
