Maintaining Rainscreen Panels

Maintaining rainscreen panels is not difficult if you have the right panel. Both Petrarch and Steni composite stone rainscreen panels are non-porous products, so they don’t absorb water. Petrarch and Steni panels repel graffiti. There is no need to add chemical water sealants to the panels. Composite stone panels don’t include any food sources for mold or mildew. The only real maintenance needed is a good power wash with a mild detergent from time to time.
