well, its smooth, but that is what we had around our pool as a kid.

The house we built on a hill had a very tall walk out basement. I was completely convinced I was going to stain the concrete, until my husband set the chainsaw down and it leaked oil on the virgin cement. I struggled with an alternative plan when my brother ( with questionable tastes) suggested that I have the floor epoxied like a garage coating. Picturing race card red, I told him he was nuts. I was amazed to see what is available now in epoxy floor coatings. We picked a coating base color in the taupe family and 3 color chips. The installer scattered the chips over the base-coat and the next day put down a clear coat. It dried within a day or two and it is virtually indestructible. Although the temps reach 110 degrees, the floor is never hot. I am not sorry I did it. It is almost completely maintenance free.

Sorry I meant to also say, that they told us this coating could be used outside. They can provide you with good size samples. You could leave one in the sun and see if it gets hot.

Many thanks to both of you. I'll do another round of research and ask about those products. Race card red would be preferable to what I have now! I even looked into astroturf but was told it would melt here. Not so far-fetched, as the sun deformed my fake Crocs when I accidentally left them out one day, lol.

Do you recall the name brand of the epoxy?

Not positively, but I think it might have been ultimategaragefloors.com. What we got was a taupe base, over which they scattered white, Black and Tan eighth inch paint chips, then sealed them with clear coar. The more clear coat, the smoother and glossier the finish. You probably want something less smooth. They have a an exterior application on the website that are available in solid colors.
