Background

The problem

After refurbishment the display panels, paints and timber kept releasing formaldehyde and TVOC. With heavy visitor flow in enclosed rooms the odour was obvious, and as an important reception venue it needed one treatment that met the standard and lasted.

Scope of work

What we did

  1. Surveyed pollution sources and ventilation in each gallery; defined treatment zones
  2. Formaldehyde-removal treatment on panels, timber structures and walls
  3. Nano photocatalyst sprayed throughout for a long-lasting purifying film
  4. Sealed reaction 8–12 h, ventilation, re-test and hand-over
Results

Results and value

Formaldehyde and TVOC met GB50325-2010 and odours were gone. The photocatalyst film keeps breaking down pollutants under light — no consumables, no maintenance.
