When it comes to effectively cleaning graffiti tags, there are a lot of variables that need to be taken into consideration before the removal job is even started.
We see a lot of situations where graffiti removal has been attempted by an inexperienced person, with the result being even more of a mess than the graffiti was to begin with. There are often cases where this has resulted in permanent damage to the affected surface.
As there are a vast number of surfaces and substrate types that can be the target of graffiti vandalism, there is also a wide range of graffiti substances used for tagging and many ways that vandals apply their tags.
Therefore, before any graffiti removal job can begin, it is vital that the substance used for the graffiti is identified, along with the type of surface affected and the extent of the staining on the substrate.
Often, when our technicians are called out to a graffiti removal job, there a number of different surface types that have been tagged, like the examples shown here. As a result, the use of a range of different cleaning solutions and treatment processes is required to complete the one graffiti cleaning job.
Painted or coated surfaces like the doors on a utility box will require the use of a cleaning solution that will break down the graffiti substance without softening the finish underneath. This type of cleaning process is usually done with a gentle hand cleaning treatment to ensure that the cleaning solution is controlled and impact on the original finish is minimised.
An important step when performing this work is to use an appropriate neutralising solution as the final step to ensure that none of the cleaning solution remains active on the original finish.
Natural stone surfaces or bare substrates like concrete require the use of a cleaning solution that will soften the graffiti substance but not allow it to soak deeper into the surface. This is where many cleaners go wrong and use solvents that simply make the graffiti soak deeper into the substrate and result in a more difficult clean up job.
On these bare surfaces, once the correct cleaning solution has had time to dwell and draw out the graffiti substance, it can be washed down using specialised pressure cleaning equipment that will rinse away the graffiti.
These are just a few examples that show the challenges of performing graffiti removal correctly and getting a great result.
So, when it comes to taking care of graffiti, be sure to call in the experts and don’t risk causing more damage to your property.
