deck question

[stevess]

firgured since i use the lower level to store the tractor this would be an appropriate question. this deck has carpeting, then plywood and underneath old tongue and groove that you can see has been repaired along time ago. about 3/4 of the deck is covered by an overhang. i need some ideas on a floor surface. please have a look at the photos and tell me what you think. the structure seems sound but the board seem like they,v seen better days. started puilling the rug because of the moist smell and man it looks like quite the project.
thanks steve

What do you want on it and how waterproof do you want it? It is well constructed and looks to be able to support most / all building materials. Tile, exotic hardwood, tar and gravel.... What do you want?

Hi, thanks for responding. I guess i'd like waterproof but cost and labor is always a consideration. i was gonna try and do it myself but i may be in over my head. do i have to remove all the boards or can i just lay something over it.... or can i refinish these boards..... or should i start fresh? i really didn't consider tar-gravel-tile or exotic wood but youve peeked my interest. thanks for your ideas! i guess labor at this point would be the greatest consideration if i can save myself time and aggravation i would gladly find more money. oh, and of course the wife has to like the look of it!

How about pressure wash the boards clean, the old junk including paint should come right off ... then maybe deck stain or water seal ??

That thing is really built well.

i was thinking the same thing but some of the boards seem to be alittle soft. how do i check? the underside as you can see looks pretty good. i was also thinking of renting a drum sander.

If the goal is to water proof the floor to protect the tractor underneath, I'd approach it by putting up something under the deck to catch and route the water to a gutter. Then just use the deck above as a plain old deck. There's been a number of threads over the years on guys that have used everything from corrugated metal to siding, they hang it something like a suspended ceiling and mount a gutter along the low edge. Some of them look better than the ceiling in some houses.

I think anything you put on a flat surface to make it water proof is going to be a hassle. It will pool water against the side of your house in a rainstorm, and will require maintenance to keep it waterproof. Every time someone drags a heavy chair or table leg along your floor it's likely to damage the waterproofness.

If you think it is soft, poke at it with an awl or pocket knife. Compare with a good piece of 2 x 4, if it goes in too easily it is because of the carpet on top of the plywood. I had a simmilar situation that I did to my porch several years ago and had to replace from joists up to deck due to rot. The layers trap moisture and it's all down hill from there. Looking at your 2nd pic in the first post i see what looks like black wood (rotting/fungus usually) and rusting nails. Rusty nails eat holes in wood. I pulled 16' 1x4's off roof rafters by hand when reroofing a shed that didn't have tarpaper put on first, turned board over and shook the nails out. You have a good size deck but I would bite the bullet and take it all off. Some one has already patched it so you will only be patching/covering a patch if you are comfortable with that. Not to pick on you but your 2nd set of pics the double 2X' on the flat for headers would be undersized for the span in CA. as the 2X on the front appears to be just decoration and not weight bearing. Like Beez says hang a roof under neath> then you can put the kind odeck you like on top>

thanks again, more to ponder. kinda knew about the span being questionable and was done along time ago so i'm not sure if actually up to snuff.

It's not up to snuff, I'd check the span tables to see what you need and get that fixed. It wouldn't be too hard, just shore up those joists and either slide in a piece of steel, or take a block off the piers and put in some 2x. Looks like that might be a headbanger, so steel would probably be better. That's probably why they undersized it in the first place.
