Tommy on the boston row house from a few years ago you put a rooftop deck with membranes etc. i have a deck on the beach that is covered in a failing (just starting to fail all deck wood is dry but our house inspector says it's time for a coating) membrane or stain (sealer) what do you reccomend for a product type that will seal the deck and last underneath feet and chirs etc for the view from the deck. it has some form of water proofing and the last owners layed down superdeck stain i want a sealer that will be durable - thanks Tommy - roland
