I am assuming you are talking about house siding, right? If not, please write back. If you used a mildewcide it should kill not just clean most of the mildew. A periodic spray of a 1:3 solution of bleach/mildewcide and water will prevent regrowth. If it is on a roof you can install a copper or zinc strip at the peak. The rain reacts with the metal and prevents mold and mildew.
Prevent mold and mildew on what kind of surface, after powerwashing ? It makes a difference to know; it could be a porous surface which would have to be treated differently then non porous.
What is the min. width of the copper strip for it to work, thanksQuote:
