Curator Slate Blacking is a specialist water-based restoration product for enhancing and restoring black slate, black marble and cast iron. It helps revive faded and dull surfaces, bringing them back to a rich black finish with a subtle sheen.
Particularly useful for slate clock cases, antique clocks, decorative stonework and period features, Curator Slate Blacking is easy to apply and can be buffed to achieve the desired finish.
When applied correctly, the product helps restore depth and richness to the surface while retaining the character of the original material. It is especially useful in antique and horological restoration, including the restoration of period slate clock cases.
Before applying the Slate Blacking, make sure the surface is clean, dry and free from dust, dirt, grease and previous residues. Any loose or poorly adhered material should be removed before treatment.

Allow the product to dry before buffing the surface to achieve the desired level of sheen. For restoration work, it is advisable to build up the finish gradually rather than applying an unnecessarily heavy coating in one application.
