Granite Le Pelley Guernsey have just completed the hand cleaning of the Bianco Sardo flamed granite facades to both Dorey Court & Martello Court office blocks, the approximate total for both blocks was 2000m² both office blocks had been build back in 2005 and had not been cleaned since completion, this showed in the accumulation of dirt build up mainly at horizontal panel joints, the cleaning involved a double clean, the first process was to apply the cleaning solution and allow it to work for two hours with a hand scrub every 30 minutes, the second clean was to apply the cleaning product and allow it to work for 30 minutes with a single scrub. The cleaning was carried out by two teams of two each team had their own powered access platform.
