Hello all - first post here. 
I'll introduce myself and my garage in another post, but I have a somewhat urgent question.
To make a long story short, I hired a highly rated local vendor (name currently withheld until this situation is resolved) to apply a multistage coating with flecks and polyaspartic top coat (very similar in description to what Armorpoxy recently posted).
My garage is brand new, nothing has ever been on the concrete and the slab is probably three months old at time of installation. I'm in Arizona, so moisture and temperature shouldn't be an issue. Vendor has used this product for years with no issues.
The floor came out looking GREAT and I was very happy with it. I was told to wait at least 24 hours before I could move in. I waited 48 hours. After 48 hours, I moved in a lot of stuff, nothing out of the ordinary. Due to timing I didn't move my three motorcycles in for almost a week.
So here's the problem. At some point a week or so later I was moving things around and noticed that my motorcycle kickstands had damaged the coating, just from the weight of the bike (no dragging or scraping - just sitting in one position). It looked like the topcoat and flakes had been pushed aside by the sideways force of the stand.
But I looked further and I could see that my lightweight fat tired mountain bike tire tread had done the same thing! Also I found where one of my motorcycle tires, which was dead cold when parked had pushed the top coat aside.
While investigating, I found that with hard, steady pressure, I could press my thumbnail into the undamaged topcoat and peel it back.
I contacted the vendor, who indicated he had not seen that kind of damage before, and he offered to scuff the existing topcoat and apply a fresh coat, on the assumption that the first coat was perhaps too thin.
The vendor came out and applied the new top coat roughly four weeks after the initial application. It looks fabulous. He was 100% confident that I could put my motorcycles back on it after 24 hours. I waited close to 72 hours. I decided to put something under the sidestand to protect the new coating just in case and to help it looks great for many years. I chose an extra vinyl floor tile, like you can buy at the big box store.
Later the same day, I went out to check on things and as you can see in the attached pics (see the one with glossier finish), the weight of the sidestand through the vinyl tile and pushed the top coat aside again.
My vendor is at a loss as to why this is happening. He has agreed to fix it whatever is necessary, but I don't want to put him (and me) through completely recoating the floor if it isn't going to make any difference. I looked at the spec sheet for the material he is using (NPI NP-344) and it was tested to a hardness rating on the Shore scale of 80D, which I have seen is comparable to a hardhat or a computer case. The vendor agrees that the coating should be able to handle the sidestand just sitting there.
So I am hoping the coating pros here can help me figure out what's wrong. Do I have unreasonable expectations? Is it the top coat? Is the topcoat not adhering properly to the materials below it?
