Good luck
These concrete stains are good for an inexpensive and fairly easy option.
Other options
If new, the concrete can be integrally colored (as discussed) and then polished to give all the benefits of polished concrete. Or the colored shake hardeners can be polished after the concrete is cured

If it was that slippery, they must have used a sealer or a crystalizer on the floor. Truly polished concrete has no sealers or crystalizers and is no more slippery than most other coatings or smooth tile. (obviously slicker than rough concrete when wet) I don't think Home Depot would use it if...
Home Depot is going to polished concrete in many of their stores. You can find details and pictures at www.shinyconcrete.com
It is the most durable finish available and not nearly as slippery as many coatings or VCT.
A concrete grinding contractor can remove 1/2" of concrete without any dust if done with the correct equipment. (wet or dry) If anyone needs one, I can recommend guys in most parts of the country and abroad.
Good luck with the floor
You could also have a company grind and polish the floor. It would, like shot blasting and epoxy, cost more than the $100 for a sealer, but it is a better final product than the epoxy.
Thnks for the heads up and Good luck
Sorry, no experience w/ RD, but if durability is what you need, polished concrete is definately the way to go. It will definately last longer than either RD or epoxy.
Good luck
yes, almost any slab can be polished and it will hold up better and look better than any coating or sealer. It will cost more than paint or sealers, but less than some coatings or tiles.
Look into polished concrete. It looks great, is tough, reflects light, can be dyed to nearly any color, easy to clean, and no worries of not properly prepping an old worn/ stained floor.
Have you considered polished concrete? For a cost that is comparable to many of the other options it is a far superior floor that can take a beating. If you prefer, the concrete can also be dyed nearly any color.
