Bronze sculptures are prized for their durability and beauty, but without proper protection, they can succumb to corrosion over time. To preserve these artworks, several finishes are commonly applied.

One of the most traditional methods is applying a wax coating, such as microcrystalline or beeswax. This creates a barrier against moisture and pollutants while enhancing the sculpture’s luster. Another popular option is lacquer, often acrylic or nitrocellulose-based, which provides a clear, durable shield against environmental damage.

Chemical patinas, like the iconic green verdigris, not only add aesthetic appeal but also form a protective oxide layer. For outdoor sculptures, specialized sealants or oil coatings (like linseed oil) are used to repel water and slow oxidation.

Regular maintenance, including reapplication of these finishes, ensures bronze sculptures remain corrosion-free for generations. Choosing the right finish depends on the sculpture’s location, exposure, and desired appearance.
