Homeowners and longtime Online Metals customers Peggy and Everett recently revamped their kitchen. The centerpiece of this modification is a stunning new DIY copper countertop! Classic, versatile, and beautiful, we wanted to take this opportunity to show off their hard work and give advice for others with similar ideas.

Tips and tricks

Material selection

The most popular materials for this type of project are Copper Sheet ASTM B370 0.0162″ thick and 0.027″ thick. Peggy and Everett used the 0.0162″ thick material.

These thicknesses are versatile. They are thick enough that the material won’t deform if there are small undulations in the backing material beneath. They also have durability and will put up with the wear and tear of life. Additionally they doesn’t require a sealant to provide extra strength. (This has its own benefits we’ll touch on shortly.)

But these thicknesses are still thin enough that it is easy to work with them. Also, they are the easiest thickness to use if you want a hammered or distressed finish.


We suggest you use a flat piece of plywood as the substrate and backing for your DIY Copper Countertop. This material is easy to find, strong, relatively inexpensive, not brittle, and easy to work with.


You can use a think epoxy, polish, or lacquer to coat the countertop if you desire. This will protect the metal from slight scratches and it also prevents it from developing a patina. Or, you can chemically induce a specific kind of patina then seal it in place.

Another option is to leave the metal bare. This will let your countertop benefit from the inherent antimicrobial properties of Copper. Lastly, if you are looking for a more rustic appearance, leave the material unfinished. It will patina with age and the slight dings of use add character.

You can also conceal seams with a bit of extra sanding and polishing along the seam.

Attaching the material

A heavy-duty adhesive is preferable. Liquid Nails or contact cement are the most popular options. Though many of our customers also like to use actual nails to help secure the edges. You can hide these under the counter if you are looking for a cleaner finish. If a more rustic or industrial aesthetic is the goal, copper rivets can be used and placed in the open.

Peggy and Everett’s thoughts and comments

Because of this beautiful addition, they transformed their cooking, snacking and meeting space into a sophisticated, one-of-a-kind culinary station. But you can do something similar!

Peggy and Everett emphasized to us that anybody can do this work. They are 72 and 77 years old and completed this with their own labor and the help of a few friends. The happy DIY duo loved working with the copper sheeting. They specifically chose this material for its aesthetic appearance. They also specifically mentioned that it was easy to handle with no shape memory.

Lastly, if you are looking for a polished aesthetic, Peggy recommends cleaning the the counters with white vinegar and Hunt’s Ketchup. Then spray on a little bit of light furniture polish for a “new again” shine!
