Balcony algae treatment at the AARhus building
The algae and discolouration are gone, leaving the paving clean and fresh again.
On a roof terrace of approx. 55 m² in Aarhus Ø, we cleaned dark concrete paving covered in algae and discolouration. Gentle treatment without pressure washing or sanding protected the surface. Afterwards, the paving was clean and fresh, with the algae removed.

The result
After treatment, the paving looks clean and fresh. The algae and discolouration are gone, making the terrace inviting again.
Efter behandlingen af vores altan med mørke fliser, der var dækket af alger, er resultatet fantastisk. Fliserne ser nu helt nye ud, og Øens Håndværker Central leverede et hurtigt og professionelt arbejde. Jeg er meget tilfreds med både service og resultat!Smilla H., Aarhus
