Avoid spraying if rain is expected within 4 hours.  The  treated  surface  will  clear  progressively  over  time,  with  thickly  contaminated areas taking several months. A further application after 3 months will assist in more rapid removal.  The  use  of  a  brush  on  badly  contaminated  areas  after 2weeks  will  assist  in breaking down the contamination. Disconnect  tank  water  if  using  on  a  roof  application.  Allow  up  to  10mm rainfall and  3 weeks before re-connecting for water consumption.
