We had one false start on Monday 11th February, when the men with the high pressure steam powered cleaning kit were on site, but the required size generator to be supplied by a (national) Hire Company, failed to show up. After much hanging about the exercise was abandoned for the day.
Tuesday morning 12th February presented a second false start and was about to be abandoned for a second time when, after much online searching, the correct sized 6.5kw Generator was found to be available at very short notice and supplied by a local Welwyn Garden City Hire Company.
The third re-start was managed successfully at mid-day.
And what success – beyond our wildest expectations, and with no apparent long term damage to the Pulhamite stone work.
Harry was the lucky volunteer to have remained on site as the action started mid-day, and was completed within 2 hours. He has produced this stunning video clip, which shows how efficiently the graffiti was removed.
The Site warnings have been removed and the Fernery is once again open.
