Once your stained glass pieces are positioned in the stepping stone mold you are ready to mix and pour your cement into the mold. You will pour the cement into the center of the mold slowly and let it fill to the edge. Once the cement has filled up the mold I normally vibrate or lightly tap the side of the mold to try and get the air bubbles to come to the surface and escape. Before pouring, make sure that your mold is in a place where it will not have to be moved until the cement has set and is ready to be popped out of the mold. If you move the mold you run the risk of allowing cement to get under the contact cement or under the stained glass pieces. Once you have poured the cement you need only wait until it has hardened and cured.
Make sure to read our article on how to mix your cement. It will cover the different types of cement including our free formula for high strength stepping stone cement.
