Frequently Asked Questions
Should I use lightweight 5 mil or heavyweight 22 mil copper patina sheet for my project?
For a detailed description of 5 mil and 22 mil see our
Copper Sheet Thickness Guide.
5 mil (36 gauge) sheets are very pliable and are easily cut with scissors. 22 mil (24 gauge/16 ounce) is quite a bit thicker and is the thickness most often used for roofing applications. It can be easily cut with metal snips. Our customers have used both 5 mil and 22 mil for backsplashes, tabletops, countertops, and bartops. Note that when using our patina sheets for these applications, you will need an additional clear coat finish to add durability. See our Copper Sealers
which may be perfect for your project. Personal preference plays a role in almost all aspects of the design and installation of counter and bar tops. In some cases, such as for a high traffic commercial bar, people will use a flood coat of a two part epoxy resin
. Check out our tutorial on creating your own Copper Bartop, Countertop, or Tabletop
and our Patina Sheet Photo Gallery
If you are using our patina sheets to create a backsplash
, 22 mil is the ideal thickness because it can be glued to existing drywall, and with a
couple of coats of lacquer
, maintain its durability. However, 5 mil can be used as well, but you should attach the copper to MDF board or another durable substrate and add several coats of lacquer. Depending on the installation process and how much wear and tear the backsplash will undergo, a seal coat of our
two-part solvent polyurethane resin
may be needed.
Which finish should I choose?
A waxed finish offers some light protection to the patina and is suitable when the copper is mostly free from contact. Note that if you are planning to apply a clear coat DO NOT order the waxed finish as the wax is NOT compatible with these sealants. We also offer a lacquer finish (one coat). For most projects, we recommended adding additional coats of either our Copper Sealants
or a flood coat of a two part epoxy resin
. Our factory-applied lacquer finish is compatible with these sealants.What type of adhesive should I use for my patina copper sheets?
Because 5 mil is a thin material it is usually attached using a contact-type adhesive. The brush on varieties are popular, and some others will use Spray 90 or Super 77 by 3M. The adhesive is applied to both surfaces (the substrate and the copper sheet), then dowels will be placed on top of the substrate, across the width and extending over the edge a bit, and then the copper sheet placed over the top of the dowels. See our video tutorial
for a demonstration. Heavyweight 22 mil sheets allow the option of using a heavy-duty construction adhesive such as Liquid Nails as well as contact cement.How do I remove fingerprints from my patina sheets?
It is much easier to prevent these stains than to remove them. If you do not use gloves when handling copper sheets, the oil from your fingers will stain the copper. Thus when handling our patina copper sheets, especially when unsealed, it is important that you use gloves to avoid staining. At Basic Copper, we handle your copper sheets using gloves and take great care to make sure the copper arrives in the best possible condition! You should avoid using cleaners on our patina sheets as they may disturb and discolor the patina!Should I order all of the material I'm going to need at the same time?
Yes. Because each piece is truly unique, you should expect some slight variations in the patina-in other words, no two pieces are exactly alike. Thus it is best to order all of the sheets you are going to need for your project at the same time.Can I order a sample?
Yes. You can order 5" x 5" individual samples of 5 mil
or a sample packet with all of the finishes
. We do not have any 22 mil samples of the patina finishes. We can however send out small samples of raw 22 mil copper so you can see the thickness.Can I use blue painter's tape to hold the copper in place without damaging the finish?
The use of any tape or adhesive to the designed portion of the copper sheet may damage the design. Even blue non-stick painter's tape on a lacquered surface may cause changes to the design appearance and should not be used. Can I bend my patina sheets?
Any bending of the material with a brake, by hand, by hitting with a mallet, etc., may damage the edge of the sheet if not done very carefully.How soon will my order ship?
Because developing these patinas is a complex and time-consuming process, there is a 4-7 business day lead time for all patina sheets. Orders can be rushed, but there is a $45 expedited fee to ship the next business day.How is your patina sheets shipped?
