In some situations, graffiti can look good and even classy if it is executed well and has something to say. However, in many places, graffiti is an eyesore and nothing more than vandalism. So, if you have suffered from some unofficial artwork on your property and want to get rid of it, then purchasing some graffiti removal equipment may well be in order. There are plenty of choices, but you need to consider the pros and cons of each option, given the different surfaces you will find graffiti on these days. Read on to find out more about the techniques graffiti removal manufacturers recommend for specific materials.
Lots of manufacturers of graffiti removal equipment specialise in masonry since much of it is applied to concrete and brickwork surfaces. All too often, large expanses of wall just look like a blank canvas to a graffiti artist. When you want to remove spray paint from masonry, it is best to avoid thinners since these can have a long-lasting staining effect which may even look worse than the original graffiti. Instead, you should opt for a jet washer. Manufacturers now produce high-powered ones that can generate several thousands of PSI. This is enough for all but the most stubborn of paints when removing it from masonry.
When you have graffiti that has been sprayed onto metal, paint thinners do tend to come into their own. Check with the supplier whether or not these will damage the surface treatment underneath, however. After all, a lot of metalwork has a powder coating finish or a lacquer application these days. However, most white spirit-based thinners will have the right effect on things like goal posts, railings and bollards.
Generally speaking, high-pressure washers are the best way to remove graffiti from wood. Hardwoods tend to be able to withstand a treatment from a pressure washer at its most powerful setting. Most manufacturers provide an adjustable nozzle which allows you to lower the pressure, something that can be advisable for softwoods. If not, then you can always stand back a little. It may take longer, but this is better than damaging the fibres of the wood itself. Sanding down wood afterwards can refresh a wooden surface to its former glory.
Many forms of plastic react badly to thinners, especially strong ones. You can use pressure washers, but thin sections of plastic may bend under their higher flow rates. Instead, try using a light thinner, such as acetone or a nail polish remover. If that does not work, then you can always paint over the offending graffiti instead.
