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

20 Jan 2026 CW Team

Vetro Power, an Indian nanotechnology company founded by entrepreneur Varun Mukhi, has deployed advanced material science solutions to help restore and preserve Kashi Math at Banganga, one of Mumbai’s most culturally and spiritually significant heritage sites.

Known for its intricate wooden architecture and historic value, Kashi Math has been exposed to decades of environmental wear. Vetro Power’s India-based service team applied its Natural Wood Protect nanocoating to safeguard vulnerable elements of the structure, with a key focus on the temple’s ornate wooden dome.

The nanocoating technology was selected for its ability to enhance durability while remaining visually invisible and environmentally responsible. The solution provides multi-layered protection, including resistance to moisture and dirt through superhydrophobic and oleophobic properties, protection against fungal growth and moss, UV resistance, and anti-termite performance—critical for long-term preservation of wooden heritage structures.

The restoration followed a non-invasive process. Wooden surfaces were carefully cleaned and repaired where required before the nanocoating was uniformly applied using specialised equipment. The coating was allowed to cure over a 24-hour period, forming a protective barrier without changing the appearance, texture or character of the original material.

Beyond structural reinforcement, the project supports sustainable heritage conservation by reducing the need for frequent repairs, chemical treatments and repeated restoration cycles. The extended lifespan of treated materials also minimises maintenance costs and limits disruption to temple activities, ensuring continued access for devotees and visitors.

The successful application at Kashi Math highlights the growing role of nanotechnology in heritage conservation, offering a scalable and sustainable approach to preserving culturally significant structures while respecting their historical authenticity.
