The task
The customer's wooden balcony had become dark and slippery after prolonged exposure to moisture and algae growth. Its smooth, dense surface made it unsafe to walk on, especially in wet weather when the risk of slipping was high. The customer wanted to restore its appearance and make it practical to use again without damaging the wood.
The solution
- Gentle algae treatment with a professional wood treatment product
- Follow-up cleaning and rinsing without pressure washing
- No sanding, so the surface remained intact
- Care to restore both slip resistance and appearance
The result
After treatment, the balcony looks clean and even, with the wood preserved intact. The surface is much less slippery to walk on, and the family is looking forward to using the balcony again.
Det er utroligt, hvad slibning kan gøre! Vores altan ser helt ny ud, og vi har fået lyst til at bruge den igen. Øens Håndværker Central var effektive og meget professionelle.Andreas F., Isbjerget, Aarhus Ø
