I'm not sure if you can. I have gone as far as 5oz per gal and it still faded it. Also, you won't notice the fading until the stucco is completely dry. I had to blend the fade with more applications with shorter and shorter dwell times, so the eye couldn't catch it. I have one coming up and the company that was responsible for removing the rust before me has just about faded a nice, light gray color to almost white. Other colors that I have seen fading with OX: green, pink, yellow and khaki. The best thing to do is test, explain to the HO what to expect, and if they still want it done, charge good because each time you see how much blending you need to do, you have to wait till the stucco is completely dry, and that can take a very long time in the shade.
