I haven’t ran into this material before. I’m assuming that sh diwnstreamed should clean it up. Has anyone cleaned this before? If so what’s your process?
Oh, that’s fascinating. Appears to be some type of fiber cement composite, kind of like hardiboard. But perhaps more porous? Might need a hot mix, similar to stucco.

Can you ask the homeowner what ir is?
Yes I will when she returns my call
It look just like uncoated hardi. Which hardi should always be coated. I’m guessing this stuff should be coated as well
Looks like cement board underlayment. Needs to have something over it. Those screws may rust with SH. What’s between the joints to keep the water from penetrating?
Looks like some type of black paper or felt paper. I couldn’t make it out completely
Rinse really good and neutralize should prevent this? They look like stainless
Is the house finished? Almost looks like the ran out of money. There’s no paint on the panels or the screws even.
I’m not sure. I left the house with more questions then answers. I’m not sure that she is aware that these panels should be painted. When I talk to her I will ask.
If you know me, then you know what my advice is.

I second that advice in this case.

Sounds like one of those walk away kinda jobs
Well there ya go. Didn’t know this type of hardi board existed. Guess the stainless screws were probably for a modern/industrial look, but no one probably thought about having to paint around them until they were installed lol!

So maybe they are finished. Thanks for the link. Who knows. The panels do look sharp. Just questionable due to the exposed cracks. If she doesn’t have any answers then I’ll pass. Hopefully she’s aware of potential issues
We call it 'CFC ’ in Aus , compressed fibre cement sheeting.
Almost indestructible.

I was just thinking this would be perfect for those brushfire prone areas, nothing fool proof, but a wayward spark sure isnt setting that ablaze.

Does it have to be painted?
@Harold fibre cement cladding is water-resistant in that is not affected by exposure to water and won’t disintegrate. Fibre cement cladding can be made waterproof with the application of a liquid or membrane waterproofing treatment. Because of its water resistant properties, fibre cement cladding is often used as external cladding and for internal wet area applications.
