I LOVE playing with concrete even though its hard to mix up and pour.
Recently I have been making stepping stones.
I buy the glass marble flat rocks for decoration they are cheapest at the dollar store.
The square mosaic tiles come in a sheet at Lowes and Home Depot.
To start out I bought a large plastic food tray at Walmart in the summer stuff, and some metal bowl pans in the dog section. I had a few plastic buckets from the dollar store to use.
Spray your mold with any nonstick cooking spray.
Mix up your sakrete as directed.
Pour some into the mold, then add the wire then pour the rest.
Let it sit 15 – 20 minutes and add the stones if they sink wait a bit longer.
Let dry overnight and they fall right out of the molds due to using the nonstick spray.
If you want to make a flower pot you will need a mold and something as the insert which will have to be weighted down. Use the nonstick cooking spray on the outside of what you are inserting in the middle and spray your mold just like before. I used some square containers and then inserted the plastic flower pots and weighted them down with rocks.
Wait about the same amount of time to insert your stones as above. You can use rocks like I used on the bigger one. Let dry overnight and both of the molds should pop right out. I made a mistake and did not allow for the drainage holes so make sure to do that first.
You can get about 4 stepping stones per bag of sakcrete maybe 5 if you do the smaller ones.
I love anything DIY and playing with concrete is fun and inexpensive.
