I am trying to find out to what extent Wolman DeckBrite can be dilluted (to run through a airless sprayer OR low psi power washer) and how effective it is. Of course, I wouldn't try to use it on wood with a seal intact, but imagine a pressure treated fence that has been out in the elements for 5 - 10 years with no sealant (i.e. significant greying, some mildew/algea coverage, etc.) Would DeckBrite be the right product & what would it yeild @ various dillutions?
