This is the BEFORE picture.
I used a push broom to clean the patio with the waterhose and bleach.
I used a stepping stone mold as a template and flipped it upside down. I then spray painted each section. (I used Rust-Oleum Hammered spray paint) I had 6 different colors of spray paint. Sometimes I mixed the spray paint colors to make the stones look real. After the spray paint dried I applied concrete sealer.
Below is a close up picture of the "stones".
It only took 2 hours and about $60 to do this project. And I plan on using the concrete stepping stone mold for another project.
