Thay should remove all that and clean before apply floor coat. have you done any new coat after you scrap? i am thinking to use laminated flooring. How much it cost? Do you have a pic to see??
They "did" remove spills and blobs and so on and clean....to a builder's standard anyway. I have no idea what floor coat even is - our flooring is just laid on a thin foam underlay. It's been down for a year and a half now and we've had no problems with it at all.
We used an Armstrong product (can't recall the name now), bought it from a clearance place in Thomastown for just under $2000 - all 100 square metres of it. That included the underlay. We paid 50% and had them hold it for us until after handover - they ended up minding it for us for about five months. Then we asked our carpet guys to recommend someone to lay it for us, and that cost another $2000. It took them four days to lay it....better their knees than ours!
The colour is "cherry" something...it's a close match to Tassie Oak, which is what we wanted. It's nowhere near as red as it looks in these photos, although it does have a pink undertone:
