It is about 15-20mm thick and it's is everywhere. I would guess it is around 20 years old and rock hard. Based on that info using your experience of how much you used on the last commercial job you did and bearing in mind each of these floors are around 70-75M2 how much do you estimate I will need?
Hi Kevin, if its that thick and 20 years old you would require a serious amount, and probably wouldn't justify the costs, better to use mechanical application for such a large job.

Costs are not important this is a refurb of a 40 odd year old office building! Roughly based on your experience of previous commercial work how much do you think I will need?
Kevin, at 15 to 20 mm thick and 20 years old it would require an enormous amount of solution i would find it hard to estimate how much, can you get your hands on one of those mechanical floor scrapers i have seen large tiling contractors use them for removing old layers of glue etc, i think they are belt-driven with an oscillating blade system, i have seen the blades they use about eight inches wide but seriously sharp and hardened to tackle your problem, i am sure the likes of HSS would have them to hire out. i would think one of these would make short work of it and save having to use any solution or maybe just a small amount to remove any left over residues.
