Cor-ten, Steel & Aluminium Sculptures

O’Sullivan Conservation considers the artistic intent when approaching the conservation and restoration of outdoor sculptures, as what may be perceived as damage could be an effect desired by the artist.

Sculpture restoration and conservation treatments can include conservation cleaning and maintenance, the restoration of finishes using specialist techniques, including airbrushing, repatination, hand retouching, re-gilding, waxing, polishing, abrasive blasting and polishing, graffiti removal and structural repairs. In the case of Cor-ten and mild steel sculptures, flaking corrosion can be particularly detrimental. Painted steel sculptures with failing paint systems can benefit from a paint colour and coating match, abrasive blast, and respray to extend the sculpture’s life.

O’Sullivan Conservation draws on its wide background to approach sculpture conservation with innovative solutions, particularly when considering structural issues and methods of display.
