Soot Removal Film (SRF)

Cleaning affected surfaces is time-consuming but necessary.

In addition, SRF proves practical in real-world applications:

• Easy to handle, as you simply spray the liquid onto surfaces to sanitize and create a film
• Allows for quick spraying of large areas
• Typically dries within 1 to 24 hours, forming a solid film
• SRF isn’t just for soot deposits — it’s effective against various types of heavy surface soiling

At BELFOR, here’s how our soot removal film can help your business:

• Effective, environmentally friendly, and leaves no dust or residue
• Prevents soot smearing, unlike vacuuming
• Almost entirely water-free, it binds acidic deposits
• Prevents contaminants and chlorides from penetrating surfaces or materials
• Often eliminates the need for enclosures
• Non-destructive and non-corrosive
• Immediately encapsulates and safely disposes of contaminants, including mold spores
• Ideal for environments and materials where water use is impractical.
• Ideal for heritage sites, artifacts or delicate stonework that harsh chemicals could damage or change chemical composition causing further damage.
• Does not require for walls to fully dry
• Produces minimal aqueous waste and small amounts of solid SRF waste

Applying the Soot Removal Film

• The SRF is a yellowish, highly viscous dispersion typically sprayed onto the surface using a special machine due to its thick consistency
• For smaller areas, you can also apply SRF with a soft brush
• Drying and Removing the Film
• After application, the film requires 1 to 24 hours to dry, depending on the conditions
• Higher temperatures and strong ventilation can speed up drying, while higher humidity may slow it down
• Once dry, the film is ready to be stripped off
• Lasting Cleaning Effect
• The effectiveness of the cleaning varies based on the surface type and the extent of soiling
• SRF works well on dry or slightly tarry surfaces like concrete, brick, stone, plaster (depending on its texture and structure), emulsion paint, and wood
• In most cases, you can repaint the treated surfaces directly without additional prep work
