<DIV>In a not too recent NASA Tech Brief, there was a description of how
NASA Engineers made a whole room's floor flat to within .001", such that air
levetated devices could work. The method they used was to pour a water
thin epoxy slow curing resin right over the concrete floor. I believe the
Engineers achieved their goal.</DIV>

that would make sense! I wonder if the polyurethane they use to cover those
tables used at restaurants/bars is thin enough to flow and level out by
itself?</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>It would be nice to be able to "pour" the
surface and let gravity do the leveling. Concrete is too viscous and
needs to be screeded.</FONT></DIV></BLOCKQUOTE></FONT></BLOCKQUOTE></DIV>
