Sandblasting as a quick cleaning alternative?

The cleaning of surfaces with the high pressure cleaner is time consuming and expensive. In addition, the result is often not as perfect as desired. Whether sandblasting represents an alternative here, you can read in this post.

Cleaning large areas

Cleaning large areas with the high-pressure cleaner is time-consuming and tedious. Despite the use of detergents, the result is often not perfect. Not every dirt can be completely removed from any surface. High pressure cleaners are used in the cleaning of

  • facades
  • paving stones
  • roofs
  • occasionally for machines and larger devices

Allow self-cleaning versus cleaning

Sandblasting can hardly be done by yourself. For the
Dry ice blasting is too expensive for the required equipment, and conventional blasting can only take place in a blasting box - it is not suitable for large surfaces.

For the thorough cleaning of external surfaces, a service provider is necessary. The costs for cleaning are thus significantly higher than for self-cleaning - but it is also without high detergent consumption and without time-consuming work to expect a perfect result.

Cleaning of wood

For wood and facades, mobile dry ice blasting is especially suitable for cleaning. Due to the incident particles of the blasting material, which in this case has a temperature of -78° C, the uppermost layer of the wood containing the dirt is shock-frozen. The dirt then just explodes.

A cleaning with the high-pressure cleaner leads here only to a softening of the wood without sufficient dirt removal. Also, the so-called "wet blasting" with the high-pressure cleaner in the outdoor area is not in all cases sufficiently effective cleaning process.

Laser technology as an alternative

For stone facades and also for metal surfaces, laser technology offers a very good alternative. Laser devices that are used for the restoration and cleaning of structures can be dosed very finely. Different lenses on the devices also allow an even more extensive adaptation to the material to be cleaned.

The advantages are obvious:

  • No blasting agents are used, so that there are no residues of blasting material
  • the process is more scalable than most sandblasting or dry blasting equipment
  • the process is more economical in use: the processing time is shorter than with comparable blasting processes
  • the process consumes very little energy

Backpack Laser

For mobile use, the so-called "backpack lasers" are ideal. These are backpack-sized, battery-powered devices that weigh about 12 kg. The laser power of these devices is - depending on the version - up to 20 watts. It uses lasers of class 4.

The working distance with a backpack laser is up to 250 mm, so that an effective cleaning of difficult to access parts is quite possible. It is possible to choose between battery operation and mains operation. Suction extraction is possible with most devices, as well as the use of specific filters within the extraction system.

Any radiant surface can be cleaned with the laser technology, often even with significantly higher efficiency and greater protection of the surface. Due to the low energy consumption, the devices are not only very economical, but also very ecological, and were therefore also awarded the German Environmental Award 2010.
