Made these tops with two layers of 3/4" treated plywood for a total thickness of 1.5". They've been exposed to the weather (sun, rain, snow) for over 12 years and look to be good for another 10 years. You can treat them with some Thompsons Water Seal just as you would for a deck, should last even longer.
