| put something in the mold that will make the concrete come out smoothly when it dries. You can use a little car wax. Also let it sit for at least 2 days. If you are really impatient you could use hydraulic cement, which dries much faster but probably wont come out as smooth. |

| I wait a week on all my molds,second you need to take a pencil or stick and just prod the mix after u pour to get airbubbles out,third go buy some clear stain varnish for wood and coat it when dry this protects it as well as giving it good slide. I rarely have to wax mine.
