Hello Permies gurus

I have an ICF foundation and have painted it - mostly so that the screaming white styrene isn't as glaring to the neighbors, and to protect it from sun damage. But soon (I hope) I am going to apply a more permanent solution.

I had seen a DIY video some years ago, where a woman used cement or mortar, like stucco, to cover over the exterior of the cellar, waited for it to stiffen up, and then carved "grout" lines, along with some stone texture details into the not-quite-hard mixture. With a little ingenuity in the mortar mix with color streaks, it looked amazing!

But I can no longer find the link, nor anyone else doing something similar - at least not with any details on what mixture to use, or how thick, or any of the other things we "users" would like to know. And for my 30x50 cellar with two sides fully exposed, I don't really want to take a lot of time to experiment, if answers are already out there. I'm sure I'll make enough errors all by myself - I don't need to repeat someone else's!

Does anyone have experience with this? Or recommendations on what product to use for a long lasting faux stone finish?

Thanks,
Randy

I have never had experience, but I notice a lot of lookers are also bewildered perhaps.
I found this;

the last one has an interesting set of choices.
