The issue sparked off from the painting of the North and East Gateways of the monument in what appeared as red and white paint. Quoting Ratish Nanda, Project Director, AKTC, from an interview in the Indian Express: “There is absolutely no white paint being used anywhere at Humayun’s Tomb. What appears as paint is in fact a 1 mm coat of lime plaster mixed with marble dust. The Mughals used it here and even at other stone buildings such as the Diwan-i-Aam at the Red Fort to give a marble like appearance to plaster/red sandstone. The white coat of plaster also serves as a protective layer to the lime plaster below, in which organic additives such as jaggery and bel fruit pulp ensure patina returns quickly.” Nanda said the efforts to remove cement layers and replace these with traditional lime plaster layers used by the Mughal builders, including the significant final layer, will no doubt give a “new” look until a few good monsoons restore the “dignified” patina.
