How to Make a Sand Mold for Concrete Hunker
Creating a sand mold for concrete is a quick and inexpensive method of reproducing ornamental objects in concrete form. The process uses fine wet sand to hold the image of the casting model. The sand is just strong enough to avoid crumbling as you pour concrete into the depression left by the mold. After a short wait for the concrete to harden, you can pull the cast replica of your modeled ...
