Topping over prestressed hollow core floor

[MDM]

Does anyone have any experience with a concrete topping poured over a prestressed hollow core slab floor? The topping is poured with the fiber added into the concrete.
I'm trying to get an idea how much it will crack, especially where the slabs get grouted together. I would like to seal it with a satin clear and use that as the finished look for an interior floor. Also, how will how it's finished change the look (machine or hand).

Thanks

This is an idea of the hollow core. A 2in topping gets pored over the whole floor to make it a finished slab. I want to acid stain and seal it once its cured, but I'm unsure if it will have cracks along the slab lines.

We have supplied epoxy systems for these in the past. There are micro-toppings out there but most are troweled, not poured.

These types of floors in our experience have movement, and hence any topping or coating can crack. A clear you wouldn't see the cracks as much so would recommend a flexible clear epoxy system. We carry these, email us for info and pricing (include sq footage and location please).
