Hello matrixarchitekt

I have already used this product for the house façade (plastering with polystyrene insulation). However, the pressure of the high-pressure cleaner is greatly reduced because otherwise parts of the façade can come loose. I am satisfied with the result with normal soiling. But the product has problems removing algae and moss particles. For these, I then use a special product from another manufacturer, which is mixed with salts.
Please make sure to test it on an inconspicuous spot to see if your façade can cope with it.

Thank you very much for your helpful answer.
