Stone Cleaner: cleaning stone facades – moss & algae removal
Graffiti, moss, algae, fungus, lichen, oil and grease stains as well as emission and road dirt – these are the challenges when cleaning stone facades, stone surfaces or stone elements. For light soiling, the use of high-pressure equipment and water is sufficient.
If the dirt is deep in the pores and water alone is no longer sufficient, our active cleaning products are used, including the special stone and façade cleaner A.K.B., which is known for its detailed safety and application instructions. A.K.B. is particularly effective against moss, algae and discoloration on various surfaces. Our products are also suitable for cleaning roofs. They are characterized by their extreme effectiveness and quickly and effectively remove stubborn lichens and algae.
Just as important after stone cleaning is the hydrophobization/impregnation of the cleaned surfaces. This is the only way to provide the stone with long-lasting protection against rapid re-soiling, weathering or rapid re-infestation by moss and algae.
