Mike and Troy came back today to stain and seal the back patio. He included stain in the cement mix, but today they added a spray on stain of brown and gray. It really looks a lot different from when they initially poured it.
We really wanted a more natural, slate / stone look, and I think they did a pretty good job at that.
I think we may have them come back one more time and add a little more brown to it, but overall we are pretty pleased with it.
Here is a final look at the whole thing from the back yard.
