Spread another one inch layer of concrete over the wire.
Let sit for two days. (I set mine in the shed.) When it’s ready, turn it over and tap on the back of the cake pan. It should release easily. Slowly remove contact paper.
If there are holes, you can fill them with cement. You can use sand paper to smooth grooves in the cement. I took a wet sponge and cleaned the entire area after removing the contact paper, then I varnished it with marine varnish.
That’s it! Enjoy your handmade stepping stone! Want more? Check out this DIY garden stone made from flagstone.
