Doff Approved Contractors
DOFF from Stonehealth, is a high temperature steam based stone cleaning system capable of removing many different types of paint and biological matter from stonework and masonry.
DOFF is most effective in removing:
- Paint coatings (most oil and plastic types)
- Certain types of graffiti
- Bird or vermin fouling
- Algae, moss, and fungi
- Wax coatings
- Chewing gum
- Bitumen, Oil, Grease and many others, all without causing any damage or disfiguring the substrate
The steam/superheated water removes moss, algae, fungi and other biological matter and also kills off spores, removing the need to use a chemical biocide during the process or as protection against further biological activity.
