How to Treat Redwood
Redwood is a wood of choice for special outdoor building projects such as decks, fences, arbors and pergolas and retaining walls because it is naturally resistant to the rotting effect of elements like sunlight, wind and water. But even untreated redwood will break down faster than treated wood. To ensure the life of your outdoor structures, treat them periodically with a preservative.
