Dryvit Mix Ratio

[rmhinkle]

I did a test spot today on some dryvit. Black streaking from the roof line. DS'd it with strong mix of 12.5% and Simple Cherry. It only lightened it, didn't look very good. I have a roof setup and was wondering if I should use it? If so, what mix ratio might be good for using the roof setup?

If it wouldnt come clean it may be oxidation. Try a light coat of F13 or simple green or something like that, scrub it and rinse quickly and see if that works better.
