The concrete in my backyard is old - discolored, has some cracks, other than that, it is in good shape. I read some things about painting or staining the concrete, possibility stenciling to make it look better. Is that a good option? Does it come out well? Is it hard to do? By the way, it's a large concrete area including the patio and areas around the pool. Thank you for any suggestions to make my backyard look better.
