Sure, ICF is an expanded polystyrene foam material - you need to render the surface, which is the process of putting a mortar mix onto the surface, thus making it a solid concrete like surface rather than EPS. From there, you can waterproof and then lay your tiles. Hope that explains it further - thanks for the comment - Andi
@@Buildahottub awesome! thank you very much. I thought maybe you were saying you have to remove the polystyrene down to the concrete.. im relieved that isn't the case! Thanks for the info
It's gonna be so exciting when I can finally start mine! Almost there!
Can you explain what you mean by "render it back" in reference to the icf
