Treatment and Maintenance Program
After initial treatment of substrate, a once-a-year light spraying will help maintain a clean, stain-free surface.
NOTE: Heavy biological deposits may require repeat applications of D2 cleaner to achieve complete cleaning after detachment. Alternatively, heavy growth can be detached by manual scraping using wooden or plastic tools immediately after application.
