Definitions

  • a mixture of 70 to 90% by weight of glass granulate and 10 to 30% by weight of abrasives can be used. Only in the case of extreme soiling and hard stones such as granite can it be expedient to utilize the upper limit of the abrasive substances specified above, namely to use a mixture of up to 60% by weight of abrasive substances and the softer component.
  • silicon carbide with a specific weight of 3.2 g / cm3 and / or corundum with a specific weight of 3.9 to 4.0 g / cm3 and / or garnet or olivine with a specific weight of over 3, 5 g / cm3 can be used.
  • the facade surface to be treated is subjected to the blasting agent by moving the compressed air jet back and forth until the disruptive dirt is removed. This can easily be determined by observation.
  • the dust, dirt and the used abrasive are expediently suctioned off in order to avoid environmental pollution. Most of the dust and removed dirt particles can be separated by sieving or sifting in order to be able to reuse the abrasive. However, this can also be dispensed with if it cannot be ruled out that the dirt content, e.g. Paint residues in the recovered abrasive result in increased dust and pollutant emissions.
