More commonly known as sand blasting, media blasting is a form of abrasive blasting. It is especially ideal for internal soot removal as it doesn’t require the use of water. CPL t/a Rainbow International use abrasive agents and compressed air to clean soot and smoke damage from unfinished surfaces such as timber, brick, and stone. The system we choose depends on the robustness of the surface and therefore we undertake a full survey before starting work. We must ensure the media used during the media blasting process is softer than the surface we are cleaning in order to prevent further damage to the façade. Following media blasting, we finish off by sealing the cleaned surfaces to prevent seepage of any remaining odours.

The TORC system is another form of sand blasting. It uses a mixture of low air pressure, with a small amount of water and a safe, soft fine medium. The system creates a gentle, swirling mixture which removes soot damage from soft to hard building surfaces. Moreover, this is another system that uses few or no chemical ingredients making it a safer alternative to other soot removal techniques. TORC systems do not cause additional damage during cleaning making it an extremely safe and successful option for listed properties.

The DOFF System is an ultra-high heat and pressure system for external soot removal from stonework and masonry. It is an exceptionally robust steam cleaning solution, which will not damage unfinished surfaces. CPL t/a Rainbow International will always undertake a full survey to ensure the most efficient media blasting technique is used to remove soot from your building.

Do different fires have different outcomes?

Yes, different fires will create different types of soot, which in turn, need to be removed in their own way. We offer different types of media blasting so that we can provide the most efficient clean-up service for our customers affected by the fallout of a fire. Whether you have been affected by a slow or fast-burning fire, or whether the fuel was paper, oil, chemical, or something else, our media blasting team can help.

Media blasting after a slow burning fire

Slow burning fires occur in spaces with reduced access to oxygen. We expect fires in small, enclosed spaces such as a cupboard or a garage to burn slowly. The smoke this type of fire produces contains a high proportion of odour which will be difficult to remove from porous building surfaces. Media blasting can help to remove soot particles from brick, stone, timber, and other bare building materials.

Media blasting after fast burning fires

Where fires have a ready supply of oxygen they will be fast burning. Fast burning fires are most common where the fire breaks the windows or the roof of the building, or if the fire started outdoors. When the flames reach the outside of a building, they will cause damage to the façade, producing large amounts of black soot. The nature of the soot will depend on the fuel for the fire, however, media blasting will always be the most efficient method of removal.
