I used to sell this stuff, if you prep the surface right it will never come off and make the concrete stronger (no cracks etc). Again, like any coating, prep is the key to making it last forever. http://www.steelcotemfg.com/p-concrete-coating.htm

But if you want a real man room....go stainless with a floor drain in the middle so you can spray it down with a hose when the party is over.
