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 D/2 to achieve complete cleaning after detachment. Alternatively, heavy growth can be detached by manual scraping using wooden or plastic tools immediately after application. In the event of excessive plant exposure, rinse all plants and water-in all planted ground areas contacted by D/2.
