Another complication in restoring the lanterns and columns to their original appearance was matching the gold painted finish. DW Windsor worked with a paint mixing specialist to achieve a colour that closely replicated the original.
Each component of the lanterns was stripped back, and all paint and corrosion were removed. However, due to the lead-based paint used in the 1930s, this had to be carried out using a chemical process under carefully controlled conditions to ensure all risks were minimised. Due to the fragile and delicate nature of the original glass, which made it a safety concern, all the glazing needed to be replaced to comply with today’s standards. All components were repainted, with care taken in the application, to ensure a high-quality finish. The lanterns were then reassembled and resealed to bring them in line with modern standards and to protect the internal electronics from water ingress. Specially designed light shields were also created and installed within the lanterns to prevent light spill onto the river.
