Hardi Board- Colored


New member
Hello all,

New to the forum. I am having a fun time trying to get James Hardi board clean. It seams that most colors clean up well with just a standard soft wash, most without chemical application. However the blues, reds, and yellows are kicking my butt. No matter what method I use or what chemicals I apply they look the same once they dry. Anyone have luck on these newer construction materials? Here in Utah mildew and mold aren’t an issue it’s mostly construction dust and hard water deposits we are dealing with.

Any success stories would be greatly appreciated!

have a great day!
