I considered stamped concrete for the concrete patio we put in last summer, but didn't like the cost.
First, I'll tell you what I did to the concrete driveway, which didn't work out after a short time, then, what I did to the patio that I personally like very much.
On the driveway, I did a concrete stain, first a sandstone yellowish color, then overlaid with a warm terra cotta (had to tone it done with black later), all with a power sprayer. It was a lot of fun, and I liked the results, for a while.
It was supposed to be permanentÂ….it's not. It wore off places where we had to drag some things over it, exposing the concrete.
Sooooo, for the patio, I approached it differently, and like the results much better. I had concrete paint tinted 2 different colors, a light butterscotch, and a darker caramel. Put down a layer of butterscotch, then taped off a harliquen pattern 12" by 6 " and painted that caramel.
What I like is that is not "trying" to look like real stone, it's just a happy, yet sophisticated pattern.
I didn't this in the Fall, before it got too cold, and I haven't gotten around to sealing it yet, but I will. Even without the sealer, it's worn very well, and any little flaws in my artwork just give it character.
BTW, I orginally bought stencils for the project, but I did better with plain old masking tape.
Go to home depot and buy a couple of those 2 x 2 concrete stepping stones, get out your paint brush, and experiment.
