Some 4'000 m2 of the concrete façades of the Hepworth art gallery in England (architect David Chipperfield) was protected in 2009 with Faceal Oleo HD against pollution, dirt and graffiti contamination by 'The Ethical Coating Company', the PSS partner for the UK and Ireland (www.ethicalcoatings.com). At the time the wall around the gallery was not treated which led to streaking caused by rain and reulted in a really grubby look (photo no. 1).
Consequently the architects asked for the protextion of the lower walls which was carried out early spring 2010 (photo no. 2).
