Dynamic and challenging weather conditions are the norm on barrier islands like Assateague, as seasonal weather patterns and occasional large storm events continuously reshape the landscape. Indeed, Assateague owes its very creation as a National Seashore to the weather. In the 1950's, some 5,000 private lots comprising what is now National Park Service land were zoned and sold for resort development.
After 3-12 months you would need to apply a wood cleaner to remove the gray wood cells. This can be done with scrubbing and or light pressure washing. After cleaning the deck you will need to neutralize the wood deck cleaner with a wood brightener. Let dry for 24-48 hours then apply your deck stain of choice.
However green treated pressure treated wood should be allowed to dry out for 30-90 days before applying the first stain. Always make sure the deck is clean and dry before you begin staining. Wait at least 24 hours after washing your deck to apply stain. Also try to avoid staining your deck right before it rains.
