Floor covering Epoxy resin Garage

nice afternoon, I don’t know if this topic fits here and/or where else I could post it here… I wanted to put Exposidharz 2K on the floor of my garage, there are tiles on it, but by now they have become very unsightly… Has any of you ever done this? I heard that this stuff hardened very quickly and…I would have to make about 40 square meters, i.e. you would probably have to be two to rub this away quickly.. I’d look forward to tips from you, nice greetings, John.
