Garage Floor Paint

I don't think there is such a thing. The vapor barrier is the 6+ mil plastic that gos down prior to the slab being poured. If there is no vapor barrier, the slab will wick up moisture from the ground. (Think of concrete as a very dense sponge) As far as I know, nothing, no coating will stop it.

As far as the comments that nothing will hold up, I disagree, As long as the vapor barrier is in place. I have seen slabs with epoxy coatings that have lasted many many years, and still shine like a waxed floor.

There are no band aids. It has to be done right from the start.

my garage was just a shed . floor was done by amatuers back around 1976. very poreous uneven and cracked . have no idea what was under it either. brought home some paint that was going in the trash where I worked. cleaned the oil spots somewhat w/ laquer thinner, and really laid the paint on heavy. the poreous concrete soaked it up like a sponge. best thing I`ve done to the place ! way easier to keep clean . one paint was grey 2 part epoxy, the other was tile red industrial concrete paint. both holding up well after a couple of yrs..
