Stone self-cleaning · Case study

Meixihu Culture & Art Center white curved GRC elements, Changsha

Large white curved facades show every stain; after coating, treated and untreated areas differ at a glance.

Project typePublic cultural building
LocationMeixihu, Changsha, Hunan
Applied toWhite curved GRC exterior elements
ProductFeibo stone self-cleaning system
Background

The problem

White curved facades demand a spotless finish, and dust and rain streaks show badly on white. The complex geometry and large area make cleaning difficult and expensive.

Result: treated vs untreated
Scope of work

What we did

  1. Surveyed element material and soiling type
  2. Local sample trial comparing treated and untreated areas
  3. Surface cleaning and preparation
  4. Two-layer application with controlled film thickness, keeping the white finish unchanged
  5. Result confirmation after cure
Results

Results and value

Treated areas sheet rain and carry dust away, staying bright white; untreated areas gradually grey and yellow — the on-site contrast is clear. The coating is colourless and transparent and does not alter the building’s appearance.
