I have a home to clean that has the stucco type siding with shells in it, I can't find anything in the search about this material. I did a test spray at the estimate with 50/50 mix and it seemed to work fine. I expect that I will treat this like a dryvit house and take it easy with the psi and let the chems do all the work. If anyone has experience with this type of siding it would be greatly appreciated if you would share your experience. Thank you

I have never seen anything like you describe, Josh. Post some pictures when you get a chance.

Josh, That's a coquina finish, very common in our area. It's very delicate and should be cleaned with mild pressure. I usually use no more than around 250 psi. Allow the chemicals to do all the work, and if you come across areas with heavy mildew/algea build up, hit with a strong does of chlorine with either a pump up, or a shurflo. When washing, you will notice a few shells come off, but there shouldn't be many. Its just the nature of the surface, you can usually barely rub your hand across it, and a few shells come off. Hope this helps.
