Bronze Sculpture Care

Caring for your sculpture and your responsibility as the owner

Gillie and Marc’s bronze sculptures are created to live with you — to be touched, experienced, and shared. Cast in bronze, they are incredibly durable and designed to last for generations. However, like all materials, bronze is a living surface that will naturally respond to its environment over time.

The finish of each sculpture is carefully considered. Some works are completed with a traditional patina, others feature painted surfaces, and in some cases, a combination of both. Each finish has its own unique character and may age and respond differently over time, requiring appropriate care depending on the materials used.

A bronze patina is a hard-wearing finish created through a chemical interaction between the bronze and elements applied to its surface. It becomes part of the material itself — a living layer that evolves over time. As the sculpture is touched or exposed to the elements, the patina may develop subtle highlights and tonal shifts, giving each piece a unique and bespoke character. This natural ageing is often considered a beautiful part of the sculpture’s life, though regular waxing and care are essential to preserve its appearance.

Painted bronze offers a vibrant and expressive finish, bringing colour and energy to the sculpture. It is particularly suited to indoor or covered environments, as painted surfaces are more sensitive to environmental exposure. Like automotive or furniture paint, these finishes may gradually fade, chip, or wear over time — especially when placed outdoors. In some environments, repainting may be required within 12 months to maintain the original look.

Where a sculpture combines both patina and painted elements, different areas of the work may evolve or require maintenance at different rates. This is a natural characteristic of mixed finishes and should be expected as part of the sculpture’s ongoing life.

When your sculpture leaves the foundry, it is protected with a wax coating that acts as a barrier against moisture and oxygen. Over time, this protective layer will wear down, particularly in outdoor environments, allowing the bronze to naturally oxidise. Without regular care, this may lead to uneven ageing, staining, or surface deterioration.

Outdoor sculptures are exposed to a range of environmental factors, including rain, salt air, pollution, UV exposure, and temperature changes. These conditions will influence the surface over time, making routine maintenance essential.

YOUR RESPONSIBILITY AS THE OWNER
When purchasing a bronze sculpture, you accept responsibility for its ongoing care and maintenance.

This includes:

  • Regular cleaning
  • Waxing and polishing (every 6–12 months)
  • Removing dirt, salt, bird droppings, and other residues
  • Maintaining and, where necessary, restoring patina or painted finishes

Like caring for a car, regular upkeep is essential. Without it, the surface of the sculpture may deteriorate over time.

Gillie and Marc are always here to guide you and should be your first point of contact for care advice. If more specialised restoration is ever required, we can help advise on the appropriate next steps.

Please note that damage caused by neglect, environmental exposure, or improper care is not covered by warranty.

SIMPLE CARE ROUTINE
Bronze is relatively easy to maintain with a simple routine:

Indoor sculptures

  • Dust every 6–8 weeks
  • Wax at least once per year

Outdoor sculptures

  • Clean every 2–3 months
  • Wax every 6 months

If the sculpture appears dull, dry, or uneven in tone, it is time to wax.

CLEANING YOUR SCULPTURE

  • Use warm water and a soft cloth or soft brush
  • Rinse thoroughly after cleaning
  • Remove bird droppings, tree sap, or other residues as soon as possible
  • Allow the sculpture to fully dry before waxing

WAXING YOUR SCULPTURE

  • Apply a thin, even layer of a clear, high-quality wax (such as Renaissance Wax)
  • Avoid products containing alcohol or turpentine
  • Once dry, buff gently with a soft cloth to restore sheen

Waxing protects the surface and helps preserve the patina.

PAINTED BRONZE CARE
Painted bronze sculptures require additional care, particularly when displayed outdoors.

Over time, painted areas may fade, chip, or weather. Touch-ups or repainting may be required depending on the level of exposure.

If repairs are needed:

  • Use fine sanding to prepare the surface
  • Apply a suitable primer for metal
  • Use high-quality outdoor acrylic paint
  • Consider a protective clear coating for longevity

If unsure, we recommend contacting us before undertaking any repairs.

PAINT REPAIRS AND RESTORATION
Over time, painted areas of a sculpture may require touch-ups or restoration, particularly when exposed to outdoor conditions. This is a natural part of maintaining a painted bronze artwork.

For minor areas such as small chips, cracks, or fading, careful touch-ups can be undertaken. This generally involves gently preparing the surface, applying a suitable primer, and building up thin layers of high-quality paint to match the original finish. In some cases, a protective clear coating may also be applied to help extend the life of the repair.

For larger areas or full repainting, the process becomes more involved and may include removing existing surface coatings, preparing the bronze, re-priming, repainting in multiple layers, and sealing the surface with a protective finish before applying wax.

While the general process may involve:

  • Cleaning and preparing the surface
  • Light sanding to create a suitable base
  • Applying appropriate primers and paints
  • Building up thin, even layers of colour
  • Sealing and protecting the finished surface

the outcome is highly dependent on the materials used, the environment, and the care taken during application.

IMPORTANT CARE NOTES
1.  Never use chemicals, cleaning solutions, tarnish removers, or any other unknown substances to clean the surface of the sculpture.  

2.  Avoid exposing the sculpture to chemicals such as fertiliser sprays, chlorine, pesticides, bug sprays, window washing products, ammonia, or other household products. Chemicals will adversely affect the patina.

3.  Never use abrasive cleaning pads, steel wool or sandpaper on the sculpture unless specifically advised otherwise. Use of such materials could mark the surface of the sculpture. The only exception is in the case of a paint repair (refer to ‘paint repairs’).

In any event, it is recommended to consult with a professional art conservator or restorer to ensure that the sculpture is properly maintained and cared for. 

These instructions should be followed carefully, and if there are any questions or concerns about the maintenance of their sculpture, please contact the Gillie and Marc gallery for guidance.

A FINAL NOTE
Bronze sculptures are designed to evolve. Subtle changes in colour, tone, and surface are a natural and beautiful part of their life.

With regular care and attention, your sculpture will continue to tell its story for many years to come.
