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.

Concrete countertop edges come in a variety of shapes and sizes. Because concrete will take the shape of virtually any form or mold it is cast into it's possible to produce the look of stone, rope edges, vines, and more. Here are a few resources for countertop forms & molds.

Contractors can also make edge forms themselves, creating whatever design their client desires. This can be done by purchasing molding products, such as liquid rubber or liquid plastic and casting custom molds. Also, there are companies that will create custom molds and forms for contractors. You can contact Preitech to find out more about custom mold making services.

Part of concrete's uniqueness is the variety of edge forms that are available. Choose one that will complement the style of your room, such as this rock-edge look.

Forms attached to the edge of the countertop framing can be smooth, rough, or patterned, such as this rope detail. To get this look, a mold was created using wooden rope molding.

Rubber Edge Molds

The use of rubber edge molds allows concrete countertop fabricators to create shapes that are not available in granite, tile, Corian, or Formica countertops. These forms are usually used in conjuction with wood supports or Melamine supports to provide backing and structure for the mold.

Here are a few rubber edge profiles:

Plastic Forms

Plastic forms are usually used for cast-in-place concrete countertop fabrication. Meaning, the countertop is cast on site. For example, contractors will take the forms and the concrete countertop mix to a person's kitchen and cast the countertops in the final position on top of the cabinets.

Foam Forms

Concrete countertop installers use foam forms for several reasons:

  1. 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.

  2. These molds also allow for unique designs & shapes on the edges not available for granite, tile, or manufactured stone countertops.

Forming with Melamine & Wood

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.

The use of melamine or wood forms requires more detail work after the initial forming process (cutting & screwing the pieces together). The inside edges need to be filled with some type of material to prevent moisture from leaking out of the form as well as create an edge profile. Typically, concrete contractors use wax or 100% silicone caulk in the edges.
