I just recently moved into a new home. The house itself is brand new with a deck (screen porch with a cooking deck).

Should I do any kind of treatment, sealing, or staining to the deck? Or, should I wait 6-12 months for it to settle/get worn in?

I thought about sanding it since, the kids have gotten some splinters from it. However, I've read in other places not to do this because, of the wood being treated. If sanding is not a good idea, anything else I can do?

I thought about outdoor carpet but, that just takes away from the beauty of the porch and deck.

Thanks.
