of the copper. This material is typically attached to a plywood substrate, or other surface, using a heavy duty construction adhesive such as liquid nails or contact cement, often with nails as well. The smoothness of the substrate is not as essential because the material is not so thin that it will emboss the imperfections. You can apply a sealant to this material if you want to protect it from scratches, want to create your own patina and preserve it, or don't want a patina to develop at all... but you would not necessarily need something as heavy duty as you would with the 5 mil. A spray-on or brush-on polyurethane or lacquer with out a two part epoxy may be fine in this case.
People also use the 10 Mil (30 Gauge) Copper Sheeting which is in between these options in terms of durability, as well as how to handle the installation. If you have a high use counter top and you prefer the 10 mil, you would probably want to use a heavy duty two part epoxy coating or at least several layers of a poly or lacquer. If it is counter top that is not used so frequently, or prefer a more rustic look where dents and dings only add to the character then it may very well be fine if you treat it as the 16 or 22 mil.
You can see several examples of copper bar tops and counter tops in our Photo Gallery
and on our Project Ideas page. Below are links to a few of these:
