This was an experiment in molded concrete stepping stone, that turned out well!
I’ve done lots of other concrete stepping stones but this is the first time putting it into this kind of mold. I don’t know what the mold was originally designed for. I found two of them at a garage sale for $ .50.
Disclaimer: I’m no expert, I do a lot of experimenting and this one turned out well. Your results may not be the same.
What you need:
- Portland cement (concrete work is messy, do it outside, be careful when mixing the concrete not to breath the dust.)
- spray cooking oil
- Some sort of mold ( plastic bin, jello mold, use your imagination )
I mixed the cement with sand at about the rate of 2 parts concrete to 1 part sand, I think 1 part concrete to 1 part sand is recommended. Mine may not be as strong.
I sprayed the plastic mold lightly with cooking oil.
I gently pressed the concrete ( mixed to the consistency of brownies ) into the mix.
Let it dry in a cool damp place for a few days. Then gently un-mold and let it continue to cure for about a week before setting it out.
