[Greenbuilding] Redoing all floors

[Andrew Pace]

Jason...acid etching the concrete won¹t remove the sealer and paint stripper
won¹t remove the stain.  Acid etching only works when the acid has ³access²
to the free lime in the concrete.  The sealer...seals it...so this isn¹t an
option.  The stain should be in the concrete and not on top of it, so
stripping wont be effective.  The only way to remove the sealer and stain
would be to shot blast.
