Adding an edge detail is a simple way to customize a concrete countertop and give a kitchen, bathroom, or tabletop a high-end, finished look. Edge details are created by using special edge forms while casting the countertop. Generally, the forms, or molds, are clamped onto a cabinet when pouring cast-in-place countertops. Many companies offer prefab edge forms in a variety of patterns. Two of the most popular options are bullnose and live edge.

Concrete countertop installers use foam forms for several reasons:
They are quicker than forming with wood or Melamine because fabricators don't need to use any saws, routers or power tools to form the concrete countertop.
These molds also allow for unique designs & shapes on the edges not available for granite, tile, or manufactured stone countertops.

Forming concrete countertops with melamine or wood can be cheaper, but it takes longer to complete. After a template is made, each edge needs to be cut with a table saw or circular saw. Once each piece is cut it will need to be screwed together to make the desired shape.
Concrete molds for concrete countertops come in hundreds of standard shapes and sizes. However if you're looking for a unique pattern or style many concrete contractors can cast a custom mold, complete with edge detail.
