I've poured the deck; I finally went for just concrete with a no slid finish. I thought to use tile or stamped concrete but I was not confortable about sliding in tile or seal every some years the stamped concrete. Let's see how this finish works.
As you can see, I used some expansion joints. I also used fiber in the concrete, and will use the sikaflex 1CSL to fill the joints; I learned here about it; thanks TFP.
Here are two pictures.
Next step is to install the venetian tile, I already have it and if there is no rain this weekend, I'll do it and hope to finish it because my litlle boy starts on the next weekend the little league tournaments and I will have a lot to games to see and little free time.
