BIRCHWOOD PATINAS

There are two main categories of patina: 1) Those which contain acids; 2) Those which do not contain acids. This
is important to know if you wish to patina iron, steel, or aluminum, as acids will cause rust or oxidation.
Types of Patinas that Sculpt Nouveau makes:
• Traditional Patinas - All contain acids
• Smart Stains and Patina Stains - Do not contain acids

Each type of patina is available in a range of colors. The colors may be mixed together within the group to form
a different shade, except for the Traditional Patinas which may also be applied one over the other. The different
types may be applied over each other or mottled around areas to make the patina more interesting.
Note: When layering the different patinas, it’s best to apply those which contain acids first.
When working directly on metal, the most important factor in using Sculpt Nouveau’s products successfully will
be to have the surface of the metal clean. Sandblasting is the best way to achieve this. An orbital sander may be
used on flat surfaces, although if this is not an option, Sculpt Nouveau Metal Cleaner is what we recommend.
When using a patina* from a group that does not contain acids, warming the metal is the best way to get them
to adhere. Warming can be done by: (1) Putting the metal in the sun; (2) Using a heat gun or paint peeler; (3)
Using a patina torch.
Sculpt Nouveau’s patinas do not protect the metals from further natural changes once they have been applied.
Also, most patinas will have a chalkiness, which will rub or rinse off. We recommend applying a clear sealer once
the patina is finished.
*For Patina Stains, heat is not recommended. If the metal is too hot the patina may end up looking wrinkled.

aluminum. Both liquid and gel formulas for M38, PC9 & M24.
