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.

The rain reacts with the metal and prevents mold and mildew.

what is the min. width of the copper strip for it to work, thanks
