Pressure wash it and then add flowers at the edge.
And then concrete paint or stain if you want a new color.
My vote is to stain it. Fades over time and easy to refresh when needed.
Call a Paver Contractor! Mine did an excellent job, and enhanced the curb appeal and value of my home.
They cover it with a new layer of concrete when resurfacing it. Just a thin layer but best leave it to a pro as it needs to stick to the old concrete. Then you can stain,,,not paint it.
Thanks so much for all great ideas
