hours.

Maintenance of Zinc coated surfaces

Pay attention to doors and lower parts of the walls. These areas have potentially corrosive
elements such as dust and humidity.
If there is damage to the zinc-coating:
1. Carefully remove any rust with sandpaper.
2. Clean the damaged area and its surroundings.
3. Coat the damaged area with the zinc coating. Use Würth Zinc 300 for a thicker coat.
On large areas, you can use Würth Zinc Spray Perfect to ease the work and to get an
even surface.
