Something that "bites" concrete is usually full of solvent.
Check the tech data.
I pulled this from the description on the POR website.
"No need for acids; no need to flood your floor with water. Just use our easy degreaser on any heavy oil or grease stains, vacuum away any dust or dirt, and paint right over everything with Floor Armor."
Again, the product may be just peachy but we all know you can't short-cut the prep.
Hate when an epoxy supplier uses the term "paint" in the description.
It is not necessarily an issue. There are no short-cuts in prep. Be leary of products that don't need or require only limited preparation.
Not sure what the definition of "EPOXY" is or if the POR-15 products qualify as one. I am sure, as a hot rod and classic car restorer of MANY years, that every one of their products I've ever used has performed as well or better than they have promised.
As for POR-15, I've only had good results except for their caliper kit that I used on rear drums. It burned off with the heat.

I can you you one thing, the por-15 anti rust paint is some tough shh!!
And does not come off you skin for weeks lol
I would bet their floor paint is quality aswell.
So I will differ with most here. I did a frame with POR15 and it ended up spending some time in sun light well after it was dried and cured. It chalked badly and faded I had to sand and redo it. Makes me wonder what would happen to their floor?

POR-15® is sensitive to UV light (sun) and must be top coated for prolonged exposure to sunlight.
Top coating is not required for areas not exposed to sunlight.
But that wouldn't be the fault of the product would it ..![]()

I would say yes. I can see your point that they aren't calipers, but calipers and drums have about the same conditions...
But I haven't lost hope in POR-15. I just won't try that particular application again. (BTW, it was done on new drums with all the necessary prep work. The only thing I see that might have gone wrong is that it was "new" metal. POR-15 tends to work better on rusted parts.)
There was an extensive thread 5 years ago discussing the POR epoxy product.

I was one of those who bought into their "minimal prep" sales pitch. I have since learned that, as you already know, there is no substitute for good floor prep. The POR-15 floor epoxy (yes, it is an epoxy with resin and hardener) looks good except where the cars' tires have lifted the epoxy off the floor. I now have bare concrete spots in those locations.
I'm actually a bit surprised to see the product back on the market, as they had stopped selling it after the initial introduction. I can only hope that during the past 5 years they have improved the formula. I do like their anti-rust products, which is why I was attracted to the floor epoxy in the first place.
Just be careful - it will probably do a fine job IF the floor is properly prepped.

I have the POR-15 floor armor in my workshop and can share my experience with it.
It was super easy to put down and skipping all that prep work was awesome. Problem is, it's a somewhat delicate coating that does not seem to have adhered all that well. Hmmm, perhaps there's something to what the flooring vendors on this forum have been saying all along about prep work...
I followed the install instructions to a T. Floor has been down since 1965. No moisture problems, ever. No stains, oil, grease, or paint. 65 degrees and low humidity at the time of application. All the pieces were in place for a great adhesion. The floor stands up well to the normal wear experienced in a woodshop. Tools on hard plastic casters being rolled around, lots of wood pieces being dropped, as well as the occasional dropped hand tool. I have noticed that with some larger impacts like a dropped framing hammer, the coating peeled up. It also shows scuff marks pretty readily. It's like the coating is just a bit too soft. All in all, I'm 6 out of 10 happy with it. Do I regret using it? No. Would I use it again? No. I certainly would not use it in my garage where the floor takes a much tougher beating. One trip across it with my floor jack's metal wheels or sliding a jackstand across it and I'm 100% sure it would just peel right up.
My 2 cents, hope it's helpful.
How old is your application? Is it the "original" or this "new" formula?
Seiously.
They are 2 different products for 2 different purposes.
Think about it...
Why would they just use the same formula for 2 different applications?
