Preparing the Metal

Good surface preparation is essential when using any cold patination treatment. The metal should be clean and free from lacquer, grease, oil and fingerprints before applying the antiquing fluid.

1. Remove Existing Lacquer

If the metal has previously been lacquered or coated, remove the existing finish with a suitable paint stripper before antiquing. The treatment needs to contact the metal surface to produce an even result.

2. Remove Grease & Oils

Thoroughly remove grease, oil and fingerprints from the surface. Curator Cold Patination Pre-Treatment can be used to prepare the surface before applying the antiquing fluid.

Once cleaned, wipe the metal dry and avoid touching the prepared surface with bare hands, as fingerprints can affect the final colour.

How to Use Curator Black LPS Antiquing Fluid

For the recommended immersion method:

1. Remove any existing lacquer or coating from the metal.
2. Thoroughly clean away grease, oil and fingerprints.
3. Ensure the metal is completely prepared and dry.
4. Dilute the Curator Black LPS Antiquing Fluid with 10 parts water.
5. Apply the diluted solution by immersion or tumbling.
6. Allow the treatment to react with the surface. At room temperature, processing is usually around 1–5 minutes, depending on the required result.
7. Monitor the colour development during treatment.
8. Once the desired finish has been achieved, rinse thoroughly with clean running water.
9. Dry using hot-water rinsing and leave the item to drain.

Always carry out a small test first. Different metals, alloys, existing surface conditions and preparation methods can affect the final result.

Immersion & Tumbling Application

Immersion is particularly useful for smaller components where an even colour across the entire surface is required.

The diluted solution can also be used for tumbling in a barrel, making it suitable for batches of compatible small metal components where consistent treatment is required.

Keep the treatment time under observation and remove the metal once the required level of darkening has been reached.

---

Direct Application

The product can also be applied directly from the bottle where a more controlled application is required. This can be useful when treating individual areas or working on larger components that cannot easily be immersed.

When using direct application, work carefully and consistently and monitor the surface as the colour develops.

---

Rinsing & Finishing

Once the desired colour has been achieved, rinse the treated metal thoroughly with clean running water. This is an important part of the process and helps stop the treatment from continuing to react with the surface.

After rinsing, dry the item using hot-water rinsing and leave it to drain thoroughly.

Once completely dry, the finished surface can be assessed before deciding whether any additional protective treatment is appropriate for the particular restoration.

Achieving the Desired Aged Finish

Curator Black LPS Antiquing Fluid produces a grey-black patinated appearance designed to reproduce the character of an aged metal surface.

The final result can vary according to the metal, alloy, surface preparation, dilution, application method and treatment time. For restoration work where an existing finish needs to be matched, always test the treatment on a spare piece or an inconspicuous area first.

For larger restoration projects, it is advisable to establish the required colour and treatment time on a sample before treating the finished piece.
