Maintaining Rainscreen Panels

Maintaining rainscreen panels is not difficult if you have the right panel. Both Petrarch and STENI 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. Engineered stone panels don’t include any food sources for mold or mildew. The only real maintenance needed is a good powerwash with a mild detergent from time to time.
