How do you make a mold for a concrete walkway?
Place the Walkmaker form at one end of the walkway. Shovel or trowel the concrete into the form, patting down the mix to ensure that it fills the corners and cavities of the mold. Repeat the process of mixing concrete, laying the form in the walkway and adding the mix to the form until the walkway is complete.

What kind of concrete is used for molds?
Using a mix like Cement All, Quick Setting Cement or Portland cement at a 3:1 or 2:1 ratio with sand is going to be your best bet. Chances are if you are building a large form, and using melamine, then you can use a low aggregate mix or a higher aggregate mix.
What kind of cement do you use for stepping stone molds?
