Default 2 Part Epoxy vs. One Part for Garage floor?

Does anyone know the differences between the (far more expensive) 2
part epoxy garage floor paints vs. the less expensive 1 parts(no
mixing)? I recently bought a Quikrete 2 part epoxy floor paint kit for
my garage. The kits are around $60, but you can't buy the paint alone!
I needed 3 more gallons and would have had to buy 3 more kits. SO, I
saw right NEXT to the Quikrete kit, a product also made by Quikrete
called "seal-krete" for garage floors and other concrete surfaces. It
claims to be "one part epoxy" and makes very similar claims about
durability, heat resistance, etc. This paint sells for $25/gallon. So,
I bought the closest color match and have almost finished the floor. I
painted over the remaining "good" epoxy paint after it had cured for
about 12 hours (hope the new stuff sticks OK).

Admittedly, it seems the two part was thicker, glossier, etc.
Interestingly enough it also didn't cover nearly as much space per
gallon as the cheaper paint did. I just wonder how the MFG can make
nearly the same claims about these two different types of paint. How
does the epoxy even work in a 1 part kit? I always thought epoxy
required "activation" as in the 2 part kits. Any ideas/experience on
this would be appreciated. Thank you!

You would have been happier with the 2 part epoxy paint. Too bad you were
too cheap to use it. In short, it can't be epoxy if you don't have an
activator to mix in to it. Epoxy paints harden via chemical reaction, they
don't "dry".

That said, I painted my garage floor with regular oil-base "porch and floor"
paint years ago before this epoxy paint became all the rage. It held up
well to foot traffic and some types of damage. Snowblower chains and
hot-tire pickup have been a problem though. It will make you a nice floor,
it just won't be as durable as epoxy.

I agree about good prep work, but I think it's more important with the one
part stuff. The hardener in the two part epoxy is a catalysis that creates a
chemical reaction which generates heat and actually (for lack of a better
term) welds the epoxy into the surface.

The two part is more durable and a better choice for a garage floor.

Of
course there are some better and some worse of both types and the most
important thing with either is the prep work. If you don't do the prep
right, you are wasting your time and money with either type.

NO PAINT OF ANY TYPE holds up well. I think your much better off to
never paint a garage floor, and once it fails bite the bullet and
strip, power wash or sandblast all the paint off returning it to
natural concrete. then seal with thompsons water seal or ssomething
similiar. so goo cant get into the concrete.

they also have big rubber sheets that are rolled over the floor.

paint is just a continius maintence chore.

just like painting cement block or worse yet brick its a terrible
idea...

Default 2 Part Epoxy vs. One Part for Garage floor?

Thanks. I think I must not have been clear in the post. What I'm still
curious about is all this 1 part 2 part stuff. Here is the data on the
cheaper product I used http://www.seal-krete.com/epoxyseal.htm

The "better" 2 part product is here
http://www.quikretecoatings.com/quik...eFloorCoat.jsp

There is roughly a $35 difference in price per gallon between these two
products. The more expensive one does include the "kit" which gives you
the cleaner/etcher. Of course, you only need a bottle of that to do an
entire two car garage. You'll need at least 3 gallons of the paint
(unless you know some way to lay it down thinner than I was). Yes,
that's around $200 with other materials for a very small garage! This
of course includes no labor assuming you are doing it yourself.

My point about all this is that it's quite confusing. If there is such
a large difference in price, I'd like to know more details on why? Yes,
the two part product "cures" on the crete. The one part "dries" ... or
does it "cure"? Honestly, I don't know the answers, and so far the
replies I have received seem the like the advertising - lacking
specific information about the strengths of the two part over the one
part. The only obvious difference I've seen is the glossy thick coat
the two part puts down compared to the one part. However, I put down a
satin finish for the one part vs. a semi-gloss for the two part. While
I'm sure the two part "thickness" is stronger, I have no idea how much
better it is actually bonding to the concrete. I guess only time will
tell. I plan to call the mfg's on both these products to see if I can
get any more specific information. Namely, what the "epoxy" component
really is in the one-part product.

Has anyone messed with clear epoxy topcoats over the paint? I'm
thinking about it, but again do not know if that would in fact weaken
the paint with more than one layer. Another question that pops up is UV
resistance. Ironically the more expensive two-part makes no claims
about this. I was thinking about using one of the two-part kits to
paint my back porch (it's very small), but not sure if the sun would
ruin it?
