Cast Iron Sculpture Restoration


Q. I am looking for a way to take the rust off of some cast iron sculptures and to put a finish on them to protect them from further deterioration. The largest piece that I have is a bust heroic size.

Walnut Shell blasting media


A. There are at least 2 ways to solve your problem. One is chemically the other abrasive blasting. There are some excellent rust stripping products our on the market. It sounds as if you would need to get at least a 5 gallon container of a good product, immerse your sculptures in product from 3 to 5 minutes, then hot water with some form of rust inhibitor and let stand before applying final finish coating.Second method would require the use of blast equipment. Media which would leave you the most natural appearance of sculpture would be dry organic walnut shell or corn cob.

Q. We have a Antoine Durenne Foundry cast iron sculpture of Venus we are trying to restore. It has quite a bit of rust. It is larger than life size so submersing isn't an option. We would like to remove the rust and put some sort of protective finish to keep this from further damage. Thank you for any input.

A. Hi, Nicole. AF's suggestion for dry media blasting sounds good to me. There are endless types of clearcoats that can be applied. But if it will be kept indoors, museum wax =>
might be the best approach. If outdoors, maybe Everbrite [a supporting advertiser] or a two-part automotive clearcoat.
