Graffiti has been considered as a detrimental act which signifies urban decay. Therefore it is considered to be an act of vandalism. Most governments have outlawed the practice, and since most of the graffiti is seen in public spaces the local governments are responsible for graffiti removal. Graffiti removal can be difficult, though the degree of difficulty depends on the surface it is made on.
Sometimes the process of graffiti removal and restoration of a space can make the surfaces look worse than before the work began. Specialized cleaning agents and proper knowledge of how the chemicals used will interact with various surfaces are required to effectively remove graffiti. The service of a proper Graffiti removal company is required to ensure that the work is done properly.
How they work
The graffiti that is created on walls and surfaces are not always the same and can use paints, chalks, waxy substances, felt-tip markers, and other substances, all of which are quite difficult to remove without specialised cleaning methods. A Graffiti removal company provides a cost-effective solution and helps to restore your surface to its original state. This is how they do it:
· Trained technicians remove unwanted graffiti using chemicals and other removal techniques without harming delicate surfaces.
· Anti-graffiti solutions are applied to the walls and surfaces and allowed to remain there for the required period.
· The anti-graffiti coating is applied following this.
· Pressure washing and repainting is the final process.
Repainting or Chemical Use
Ø Repainting: Very often, painting over the graffiti is a method used by a Graffiti removal company. This is a low-cost method but can have negative effects. It can develop a “patchwork effect” on the surface. Repeated and regular use of this method on the same surface causes the paint to peel. Therefore the method is not a very popular one.
Ø Chemical Removal: This method effectively removes the graffiti using cleaning products with active chemicals. However, poor application can cause damage to painted surfaces. The method is gradually becoming outdated, as it is not environmentally sustainable.
In the present day, the trained graffiti removal technicians are using environmentally sustainable products so as not to cause any effect on the environment.
Facts of graffiti removal
Four things must be understood when graffiti removal is done.
· Time is a factor as the longer the graffiti remover is in contact; the deeper it will penetrate.
· Temperature affects the rate in which the graffiti remover products operate.
· The agitation used in the application of graffiti removal products helps to break the bond between the graffiti and the surface on which it is done.
· Using the right chemical.
The idea is to adjust one variable to suit any changes in the other. That is, the contact time between the graffiti and the remover should be increased if the temperature is cold or increase the temperature by using hot water pressure. All good removal companies keep these things in mind while doing their job, and these are the companies that should be hired.
