Lol how can you accidentally use that ? . From what i can see, its a floor adhesive designed to stick tiles onto floorboards and such... From my limited experience of doing a floor with pre mixed (once) if you leave it a good few days resisting walking on it I think it will hold myself. I think some of these guys here are guilty of being a little "jobsworth" on this one personally. Floor boards move about, Screeded floors are solid. If you had used non flexible adhesive on floor boards then you would have been stuffed but this way round will probably be ok. OMG i just saw,, you ripped them all up.. oh well,, live and learn burp
Lol!!!
