Does anyone have any suggestions for a paint type or process for a pool deck that is both thick (to prevent splinters) and durable? Not looking for a clear coat...

I used a good quality specific deck pain in white on my deck and it was very durable. There are many brands out there, but you have to pay for a good one. I found one by asking the paint department in my local hardware store.

Did you put peimer down first? Or just paint right on top of the wood?

Christoper, I power washed it first, it was very old wood; had a coat of latex on it from previous attempt, but the exterior paint I bought held up well and just clean and repaint every summer because of how I want it to look, although anyone else would say it was okay.
