We built our house almost 3 years ago. It is on a slab with vinyl siding and a light greyish khaki colored stucco over the slab. During the construction process we got a lot of red clay stains on the stucco and it looks horrible. We have tried professional pressure washing companies to no avail. I recently saw some pictures of someone who had a similar situation and was able to paint the stucco to cover up the hideous stains. What type of paint should i look for to do this? I have a friend who has experience painting with a gun who can do it for me, I am just not sure the type of paint or the process. Thanks
