A Detailed Look At Commercial Graffiti Cleaning Methods

Commercial graffiti has long been used for decorative and promotional purposes. You can find them in corporate offices, educational institutions, shopping malls, chic retail shops, cafes, and restaurants. But have you ever wondered what happens when these works of art need to be removed? That is when the various graffiti cleaning methods come into the picture.

Most Effective Graffiti Cleaning Methods

Graffiti cleaning requires time, knowledge, skill, and years of practice. Only trained professionals can remove graffiti from various surfaces without causing damage. Commercial cleaning services in Sydney use sophisticated equipment, specialized products, and specific techniques based on the:

  • Age of the graffiti
  • Type of paint used
  • The type, absorbency, and porosity of the surface

Since different surfaces respond to different types of graffiti cleaning products and methods, choosing the right method is crucial. Here are some of the most effective graffiti removal techniques that commercial cleaners use today:

Painting Over

When it comes to removing graffiti from painted surfaces, sometimes it is easiest to just paint over it. Try to remove or lighten the graffiti as much as possible before applying paint. Remember, sometimes graffiti paint bleeds through new coats of paint. That is why you should first apply a sealer coat and then paint the entire surface.

To see if the graffiti marker is bleeding through, you should do a test on a small surface. You may also choose a dark color to paint over the graffiti. This way, the marks will be less or barely visible even if they manage to bleed through.

Chemical Removal

One of the most reliable graffiti removal methods is chemical removal. Commercial graffiti cleaners use a wide variety of chemical solvents to remove graffiti from various surfaces. Alcohol, acetone, lacquer thinner, methylene chloride, mineral spirits and turpentine, methylene Chloride, and naphtha are a few of the solvents you can use for this purpose.

Though the chemical removal method is highly effective, it has some risks. Firstly, you should be extremely careful when handling chemical solutions and wear protective gear to avoid injuries. Secondly, the harsh chemicals may damage certain surfaces. That is why chemical removal is only appropriate in certain scenarios.

Pressure Washing

Pressure cleaning is the most popular and satisfactory graffiti removal method. Although this technique is suitable for all surfaces, commercial pressure cleaning is ideal for artificial stone or brick surfaces. Because of its high cleaning power, no chemical usage, and low water consumption, pressure washing is also an eco-friendly way to clean graffiti.

Sandblasting

Sandblasting is a relatively new method that many graffiti cleaning services are using these days. As the name suggests, sandblasting involves blasting sand or some other abrasive material onto the surface using a jet spray. The coarse stream hits the surface and chips away the paint. Besides sand, cleaners may also use other mediums such as steel shots, steel grit, powdered abrasives, and copper slag depending on how stubborn the paint is.

Sandblasting is one of the quickest methods for cleaning graffiti. However, because it is one of the harsher methods, it may not be suitable for all surfaces. Suitable for the toughest cases, sandblasting is generally safe for concrete, metal, brick, masonry, and wood surfaces.

Dry Ice Blasting

This is another innovative graffiti removal technique that is gaining popularity in Sydney. Here, dry ice pellets are ejected from a jet spray and sprayed on the painted surface at high speeds, over 150 m/s. The paint layer becomes brittle due to a high difference in temperature and comes off.

Any competent commercial cleaning company will tell you that this is the best method for removing graffiti from sensitive surfaces. It is ideal for areas and surfaces such as glass and tiles where sandblasting is too risky.

Graffiti Cleaning Methods In Different Surfaces

The choice of cleaning method, equipment, and products will ultimately depend on the type of surface. That is because some techniques are highly effective on some surfaces but damaging on others. The same applies to cleaning products. That is why graffiti cleaners must know how to treat each surface safely.

Metal

Metal surfaces can generally handle a wide variety of cleaning methods. To clean graffiti from a metal surface, you can use the following steps:

  • Wipe the paint off using paint thinners such as lacquer thinner, mineral spirits, or acetone.
  • You may also use light-penetrating oils such as graffiti removal products.
  • Use sandpaper or bronze or steel wool to gently scrub the surface clean.
  • Try high-pressure washing if none of the methods works.

Wood

You need to treat wood surfaces gently. To remove graffiti from wood surfaces, you can try these steps:

  • Start by applying mineral spirits to wipe off the paint. This only works if the wood is in good condition and has varnish.
  • Avoid using mineral spirits on weathered wood surfaces, which will absorb the spirits and embed the paint deeper into the wood.
  • Try a low-pressure power washing method. But make sure it does not drive the paint deep into the grain.

Graffiti removal methods

Plastic

Removing graffiti from plastic surfaces should be easy if you carefully follow these steps:

  • Wipe the surface with graffiti cleaner or light-penetrating oil.
  • Avoid using paint thinners since they can cause clouding in clear plastics and even soften the plastic. Some paint thinners can permanently damage plastic surfaces.
  • To remove stubborn paints, use ultra-fine steel wool to gently scrub the surface.

Masonry

There are several suitable cleaning options for masonry surfaces. But the ideal option is to go with power washing.

  • Use a low-pressure power washer to wash the surface. Do not exceed 700 psi pressure.
  • You may also use sandblasting, but be careful not to etch the surface.
  • If none of the other methods works, try painting over it.

These are some general guidelines you must follow when cleaning graffiti from different surfaces.
