The task
The balcony of approx. 30 m² was covered in green algae, with slippery patches developing. The problem was especially noticeable in winter, when snow and moisture collected on the surface. The wood was uneven, discoloured and potentially dangerous to walk on. The customer wanted a gentle, effective solution that would not damage it.
The solution
- Algae treatment with a professional specialist product for outdoor wood
- Washing and rinsing without pressure washing to protect the wood
- Focus on slip resistance and an even, durable surface
- The entire task completed in one day
The result
The algae and green, slippery growth were removed. The wood looked clean and even again, and the balcony became slip-resistant and safe to walk on. The result was achieved without affecting the wood or the environment.
Jeg var bekymret for, om en behandling kunne skade træet eller miljøet, men Øens Håndværker Central brugte en skånsom metode, der fjernede algerne uden at påvirke træets struktur. Nu ser vores altan flot ud igen!Charlotte K., Nicolinehus, Aarhus Ø
