Laser graffiti removal machines use advanced laser technology. It uses a laser beam to act on the graffiti surface directly. Its working principle and advantages include:

  • Precise positioning

Laser technology can accurately locate graffiti on the wall. It enables high-precision removal.

  • Non-contact

Laser removal is a non-contact method. This avoids physical damage to the wall surface.

  • Efficient and fast

Laser removal is faster. This instantly removes graffiti and improves maintenance efficiency.

  • Wide applicability

The laser graffiti removal machine suits various wall materials. This includes brick, stone, concrete, etc.

Introducing laser technology can overcome many challenges of traditional graffiti removal methods. A more accurate, efficient, and environmentally friendly graffiti removal process can be achieved.

Before using a laser graffiti removal machine, take essential safety measures. This ensures operator safety and a smooth graffiti removal process.


Before using a laser graffiti removal machine, take important safety measures. This ensures operator safety and a smooth graffiti removal process.

1. Detailed training

All operators must receive detailed training in operating the laser graffiti removal machine. They need to understand how the equipment works and operating and emergency procedures.

2. Personal protective equipment

  • Safety glasses: Wear safety glasses that meet safety standards. Protect eyes from laser radiation.
  • Gloves: Wear protective gloves. Protect hands from laser radiation and possible graffiti residue.
  • Protective clothing: Wear professional protective clothing that covers most body areas. Prevent skin contact with the laser.

3. Preparing the surrounding area

  • Provide visible safety signs around the operating area. Make sure others know that laser graffiti removal is taking place.
  • Cover the surrounding area with masking material. Prevents laser radiation from spreading to non-target areas.

4. Protective equipment inspection

  • Check the laser graffiti removal machine’s protective equipment before operation. Make sure it is intact.
  • Check equipment regularly. Make sure all safety devices and emergency stop buttons are functioning properly.

5. Emergency plan

  • Develop an emergency response plan. This includes emergency procedures for equipment failure, personal injury, or other unexpected situations.
  • All operating personnel should be familiar with and strictly follow the emergency treatment plan.

Machine settings:

Before laser graffiti removal, proper machine setup is critical for safe and efficient operation. Here are detailed instructions and suggestions for adjustments based on different situations:

1. Calibrating the laser machine

  • Make sure the laser machine’s calibration is accurate before each operation. Ensure that the laser can accurately hit the surface of the graffiti.
  • Follow the calibration guidelines provided by the manufacturer to ensure your equipment is accurate.

2. Adjust laser intensity

Adjust the intensity of the laser according to the type of graffiti and the material of the wall. Minor graffiti may require lower laser intensity. The intensity can be increased moderately for graffiti that is more difficult to remove.

3. Set laser focus

Make sure the laser focus is accurately focused on the graffiti surface. Adjust the focus depth to suit different wall surfaces.

4. Set scan speed

Control the scanning speed of the laser machine. This enables it to be both efficient and precise during processing. Depending on the graffiti’s density and the wall’s characteristics, the scanning speed may need to be adjusted.

5. Consider cooling systems

There may be large or dense areas of graffiti. Consider whether the laser machine is equipped with an adequate cooling system. An efficient cooling system helps maintain laser machine stability and performance.

Laser graffiti removal is a precise and efficient task. Correct operating procedures will ensure optimal cleaning results and operator safety. Here are the detailed steps and tips:

1. Regional division

Divide the graffiti area into small areas. Make sure the laser covers the entire area systematically. Conduct small-scale testing. Determine a suitable area for laser treatment.

2. Laser machine positioning

  • Position the laser machine exactly on the first treatment area. Make sure the equipment is stable and safe.
  • Adjust the focus and intensity of the laser machine based on the previous settings.

3. Start the laser machine

  • Start the laser machine. Make sure the equipment starts working according to predetermined parameters.
  • Verify that the cooling system is operating properly. Maintain laser machine stability.

4. Systematically deal with

Use a systematic approach to gradually treat the entire graffiti area. Clean from top to bottom or left to right. Avoid treating the same area twice. This allows the laser to cover the entire surface evenly.

5. Monitor laser effects

Watch the results of laser removal to ensure the graffiti gradually disappears. Adapt to different parts of the situation if necessary. Laser parameters can be adjusted during processing.

Check and further cleanup:

After completing laser graffiti removal, conduct a careful post-treatment inspection. This is a crucial step to ensure that the entire process does not cause any damage. The following are post-treatment inspection steps and further cleanup methods:

1. Post-processing inspection

  • Visual inspection

Visually inspect the entire wall surface. Make sure that the laser removal process does not cause any damage to the graffiti area. Pay attention to the consistency of wall color and texture.

  • Touch to check

Gently touch the wall surface with your hands. Check for any bumps or uneven spots.

  • Light inspection

Use light to illuminate the wall surface. Check for minor damage or residue that might have gone unnoticed. Light reflections are checked to ensure there are no defects on the surface.

2. Further cleaning methods

  • Treatment of minor residues

Check for slight residue after treatment. Clean further with gentle wiping or vacuuming.

  • Surface repair

If there are minor scratches or damage, consider repairing them with a surface repair agent.
Choose a repair agent suitable for the wall material. Ensure the repair results are natural and traceless.

Careful inspection and further cleaning where necessary is a must. Ensure that the entire process of laser graffiti removal is safe and effective. And it will not cause irreversible damage to the wall surface.


Laser graffiti removal machine is an advanced and efficient technology. It provides city managers and maintenance personnel with an innovative solution. In an ever-evolving urban environment, adopting laser graffiti removal is a critical step towards cleaner, better cities.
