I have a friend who is building a deck using Cedar and was wondering how to seal it? The contractor told him not to use Thompson’s Water seal, but to get a “good brand” and to wait a while before applying the sealer. He called me to ask for advice and that is why I am asking all of you for help. How long should he wait to apply a sealer to the cedar boards and what brand would be appropriate for this application if Thompsons is not the best? Any help would be greatly appreciated! Thanks
P.S.- We live in New York, so the winters are bad, but terrible. And the summers are hot and humid like most places in the summer.
