The TOA one is probably epoxy paint. I have used epoxy on a garage floor and engines can be dragged across it with no adverse effects.
You'll need two coats the first on bare concrete will be 80% thinners, then the usual mix. Why? because the dry concrete will very quickly absorb the thinner and carry the pigment into it. If you do the first coat regular there is not enough thinner and the pigment simply sits on the surface.
Also you should thoroughly clean/etch the surface with hydrochloric acid. 10 parts water 1 part acid.
The above was told to me by the paint rep.
