What can I do if Advantech was mounted,glued and ring nailed in the wrong direction? Can I apply a new floor over it and have no probs? I didn't realize the lumberyard sent me this instead of 3/4 tounge and groove.

This is a 4 x 8 sheet product. What is the application? Is this an exterior deck or enclosed house deck. I assume, the decking was simply installed parallel with the joists rather than installing the length perpendicular. It is not as desireable, but on 16 inch centers or better, should not make much difference for any finished floor. You always have the option to install an additional layer of underlayment to increase stability.

I installed the advantech like any other 3/4 decking. Across the joists spaced 16 inches on center. I am building a 3 season New England 12x16 deck with roof over. This will be insulated at the floor and completely enclosed. The reason I new something was wrong was when I got to the end I was 1.5 inches off. The advantech measures 47.5" wide and the tounge is the other 1/2 inch.I think I will just go over with 5/8 sanded plywood for my subfloor. What do you think?

I would treat this the same as any subfloor. Its sole advantage is that it is made with waterproof glues and coatings. The use of a 1/2 or 5/8 plywood underlayment will add stability and allow you to lay just about any finish floor (wood, laminate, vinyl, carpet). If you are installing tile, I would use a cement board. This is pretty standard practice since it is very hard to get subflooring (deck) to be smooth, and the seams tight.

You could glue & block it, then nail the 6" o/c to the blocking.

Check with your sruct. eng. & building inspector first though.

I had an apprentice get through 8 sheets, glued & tatoo'd before we caught him.He was putting the sheathing down in the wrong direction too.

We were allowed to block it out, it actually ends up a stronger substrate, done correctly. Be it wood joists, not I joists?

Like I said check first though. Some B insp. want it all by the book so the Str. Eng. may have to draw you the detail & wet sign it.
