Converting Concrete porch floor to stone floor
I presently have a concrete front porch that was "sealed" with a rubberized sealant about 8 years ago. Last year I acid washed it, roughed it up and tried to paint over it with sand mixed into the porch style paint. It started chipping by the end of the summer. I would like to build a irregular stone floor on top of it to give the house a cottage like look. It is about 12 X 6 and covered with a roof. What type of stone, how thick, what type of base, how do I prepare the existing foundation etc for a project like this? Or am I crazy and should sub it out?
Thanks ahead of time!
