I was asked if a exterior deck (5/4PT) could be sanded to remove cupping, splinters, and use marks. Would it be worth the effort? Do you think the wood would continue to cup and splinter?
Thanks

These nonsensical posts will keep your post near the top until somebody that can actually help sees it and chimes in.

It can be done -- I did it. Though my deck was 2x redwood. Used a belt sander (and a lot of belts).
Note that even the new PT is somewhat toxic. Control the dust.
Oh, and you can't remove a whole lot from 5/4 before you've compromised it's strength (even more).
I used a large orbital floor sander on my cedar deck to smooth it out a little. It worked but the slight uneveness of the deck boards made it a bear to control the sander. It wanted to hop around a little.
Splinters in SYP can run deep. I doubt you can sand it enough to make it worthwhile.
I'd use a hardwood floor sander, plenty of high quality dust masks (the only real problem with the CCA pressure treated wood was the dust, from what i ever read) and you need to deal with the fact that you will sand off the galvanizing on the top of the nails, unless you set them all below the level of your sanding.
I dont know bout the quality of the finished product and would prepare a proposal to replace the decking and lead the customer in that direction if I were you.
Obviously they did not treat it regularly and a good sales pitch on a low maintenence synthetic decking would be in order!!
I have sanded decks with hand tools until I decided to try a floor sander. I rented the type that is a large rectangular pad (much like a very large palm sander). These sanders are not overly aggressive and work like a charm on a deck. It did a fine job of getting rid of any minor cupping I had. I should point out though that my deck was cedar, not PT.

I did my small deck with a belt sander. It was WRC so the dust was not too bad and it was breezy anyway.
If I had kept the house I might try a large floor model. The nail heads are going to get pretty thin.
