Greetings,
On my beach house project, the local lumber supplier mistakenly delivered 30 sheets of PT plywood. Before I have them pick them up, I thought I would get your thoughts on what might be a good impervious deck. I am looking at this because on my sloping lot, I will have a deck below as well, and I thought that if my upper deck was impervious, then the lower might be an outdoor room when the weather is wet as it often is in Oregon.
Thanks,
mt
Mike Oehler is now recommending EPDM liner for underground cabin roofs. There are also membranes that can be had from roofing supply places, then possibly a wood deck on sleepers over that. There are expensive deck coatings I have seen used on apartments also. Commercial flooring guys had a lock on the process so you had to buy from them -- not always a bad idea in specialized applications though.
Here's a link to an earlier product discussion:

We used EPDM on the Parent's Getaway.
Good to know. Now you can give us performance reports, Chuck. I understand that it is pretty good material.

Better hope those drains never get plugged in the winter :o :o I'm sure you have a door onto that deck , is it raised up a couple of inch's?
We have done two similar decks , one is open at the edges and sloped to drain ,

We scuppered it like this , 4 ea. spaced evenly , the Versa deck which is a sort of cross between vinyl and EDPM , rolls right uinto the scupper.
Come to think of it that rotten place we worked on last month now has three new Versa deck surfaces , they all drain right of the edge , sort of like the firts photo.
I'll try to get a few photo's of those decks .
BTW the ply under neath is not treated , I doubt Chuck is either, they want a good smooth face , and come to think of it I did one about ten years ago over in Mount Vernon , Wa. when that stuff was new , they at that time wanted a AC 7 ply , plywood. The last few where just T&G ply , 1/2" wonder board over that and floated smooth seams , nail heads etc .
What under your Chuck?
A buddy of mine did a similar type deck he had a Rhino liner guy come and spray it on , which was PITA as the guy was set up more for you to come to him , kinda hard to drive a deck to his shop , anyway Garry got it done and said it worked well . He even thought about some way to set up to do the spraying , but Garry's always been a "Great dreamer / inventer " of the next get rich quick setup, he's still normal / middle class ::) ;D
