I’m building a new home and initially we opted to cover our new “polished” (finely troweled and sealed) concrete slab with laminate flooring. Construction commenced and the slab has all the scratches and scrapes from construction now but we’ve decided against the laminate overlay and want to re-polish and seal the slab as a finished floor. The scratches aren’t deep and I’m wondering how in depth the grinding/polishing process needs to be. Will one pass with a 400 grit pad be enough or so we need to start at 80 and work up?

I don't think we have any people that specialize in that type of work. I don't know if maybe light scratches would disappear with a sealer coat.
