Graffiti attacks on bare surfaces like concrete, brick and stone can be a real problem, and something that no one likes to have happen at their property.
When it does happen, it’s natural to want it removed immediately, which is actually a good plan as it helps deter more graffiti and sends a message to the offenders.
As there are many types of bare surfaces with varying degrees of porosity and hardness, along with many different types of paints and dies used for graffiti, care needs to taken in order to protect the surface being cleaned and prevent any permanent damage or scaring.
It is important to know what surface type you are dealing with and the substance used for the graffiti so that the correct cleaning solution can be used in order to avoid creating further problems.
The use of a chemical that is too strong or not compatible with the surface being cleaned can lead to instant damage to the finish or will slowly eat into the substrate for days after the treatment process and lead to long term problems.
For example, some of the potential issues are things like:
- The use of chemicals that can burn, bleach and acid etch surfaces
- Incorrect treatment dwell time that can allow the graffiti to actually soak deeper into the substrate
- Care not taken to protect surrounding surfaces from chemicals or waste run-off
- High pressure cleaning that can lead to marks and scaring of the surface and mortar
- Water and waste can enter into building areas causing internal damage
- Abrasive cleaning techniques that permanently damage hard surfaces
- Damage to bricks that leads to issues with rising damp and salt deposits
These are just a few of the issues we have seen over the years caused by the use of harsh chemicals that are not suitable for the surface being cleaned, or by an overly aggressive cleaning process that has scared the substrate.
When brick, stone and concrete surfaces are damaged by incorrect cleaning treatments, it can not only leave a visible mark on the substrate but also cause issues with salt deposits and rising damp from moisture that can more easily penetrate into the substrate as a result of the surface being more open after the cleaning and will lead to things like premature brick crumbling and structural failure.
Our Technicians are highly trained to understand all the types of surfaces we encounter and the cleaning solutions that can safely be used on each. Along with understanding the different substances used for graffiti and the processes required to deal with them.
Each of our Technicians carry a large selection of cleaning solutions in their surface restoration vehicles, which allows them to arrive on site and be ready to correctly deal with any graffiti removal situation the first time.
So if you have graffiti that needs to be cleaned at your property, give our team a call to have it dealt with correctly the first time.
