Answer: You should be able to sand off the sealer and the redwood will return to its normal color. Redwood retains its color all through the wood. I'm a little confused about what you may have purchased - was it a sealer with tint or stain? Or perhaps a solid color sealer? In any event, you should be able to sand it off. I make my own sealer for decks and patio furniture by simply mixing one part linseed oil to two parts mineral spirits. You can use either boiled or raw linseed oil and if the fumes of mineral spirits are too strong for you, you can purchase an odorless type. Best wishes with your patio table!
