Suzi had some old etchings on her walkway that she would prefer to have had removed.
Though I hadn't specifically chiseled out an entire piece of concrete before, I offered to do it for her.
I had to purchase a small chisel and mallet set at Home Depot and then slowly work my way through the entirety of the etching so that I could remove the old words carved in and fill it with concrete filler.
It actually came out really well all in all. It will probably take several months to a year to have the concrete colors blend properly, but in time it should be pretty invisible.
