Vetro Power Uses Nanotechnology to Preserve Mumbai's Historic Kashi Math

Published on Construction World | 20 Jan 2026 | CW Team

Kashi Math at Banganga, one of Mumbai's most significant heritage sites, has been preserved using Vetro Power's advanced nanocoating technology. The site features intricate wooden architecture that has endured decades of environmental damage.

Vetro Power's team applied its Natural Wood Protect nanocoating, focusing on the temple's ornate wooden dome. The solution works invisibly, it protects against moisture, dirt, fungal growth, moss, UV exposure, and termites, without altering the appearance or texture of the original structure.

The team followed a non-invasive process: they cleaned and repaired surfaces, then applied the coating using specialised equipment, allowing it to cure for over 24 hours. This approach creates a protective barrier that extends the material's life without any visible change to the heritage fabric.

The project also helps make long-term maintenance more sustainable, it reduces the frequency of repairs, limits chemical interventions, and minimises disruption to temple activities. The project demonstrates how nanotechnology can play an increasingly important role in heritage conservation, offering a scalable, responsible approach to protecting historically significant structures for generations to come.
