Cleaning and protecting gravel plates - Kentalis prof. Huizingschool
After cleaning the gravel plates and window sills, these elements were provided with the transparent protective layer Stone Coat.

Goal
The gravel slabs and window sills of this building had been affected by dirt, moss and algae over the years, which made their appearance and maintenance difficult. After thorough cleaning, these elements were treated with Stone Coat, a transparent protective product that preserves the natural appearance of the gravel slabs and window sills. Thanks to the invisible protective layer, moss and algae have significantly less chance of adhering to the surface. This keeps the slabs and window sills clean for longer and retains their fresh appearance, while maintenance becomes easier and less intensive.
