Carbon build up and stains on brick walls and cement are usually the result of smoke damage or soot from a fire. Although this type of build up can appear as if it will simply wipe off, the black stains can be very tough to fully remove.
Even though masonry surfaces are very hard, they can also be extremely absorbent and soak up stains deep beyond the surface.
The carbon build up, or soot, consist of small particles and produce a black oily residue as a result of stalled combustion. As a result, attempts to wash or wipe away these stains usually have little impact and often make the stain worse.
In order to effectively clean black soot stains from surfaces, the use of a specialist cleaning solution and treatment process is vital. When done correctly, this will draw the dark colour stain and oil out of the substrate where it can then be effectively wash from the surface.
However, simply treating and cleaning these stains after a fire is just one part of the process.
What many people don’t realise that as part of the combustion process during a fire, an acid is produced as a bi-product which then will severely affect metal surfaces long after the fire has gone out.
In order to prevent on-going corrosion and damage to the building, it is critical to chemically neutralise this acidity and ensure no long-term corrosion problems or lingering smell.
Odours from fire and smoke is one of the hardest to eradicate!
Even painting over the surface with multiple layers won’t remove the smell.
Through our engineering experience we have developed a masking agent to suppress the smell of fire and smoke, so you can truly be rid of all traces of the fire.
