Georgia
Homes around Lake Allatoona sit in constant humidity and shade, which is the combination that grows algae and mildew on a north wall faster than anywhere else in north Georgia. Cartersville's older stock in town adds painted wood and stucco to the mix. Rhino Shield is a high-build coating that sheds water and carries mildew-resistant additives, so the wall stays clean rather than needing a wash every spring.
