Options for Shiny Floor Reflections?

[Roger Alexander]

For shooting music videos, and you don't have the access to plexiglass for the "shiny floor with light reflections" effect, I'm usually forced to just wet down the floor with a water bucket and a mop and then shoot really quick. Problem is, this water dries up super fast. Especially when shooting on concrete.

 

Are there other options for maybe using a different solution to put on the ground to make reflections that won't dry up as fast as water? Or maybe tips for shooting that will make the water last longer before drying up? (obviously minimize the wind or draft in the room, but anything else?)
