Repairing a small section of epoxy coating?

[Zoggan]

I have a couple of small areas 3" X 5" that need to be repaired. This is a Polyaspartic coating and I've ordered a "touchup" kit from the manufacturer. How do I apply the new epoxy? Should I make a cut around the damaged sections and scrape down to the bare concrete leaving nice square edges and then fill in with repair epoxy to the level of the existing?

If I just grind down the bad area and apply the repair epoxy, won't the repair be obvious? how will the new epoxy stick to the old stuff unless I scuff that too? It appears to me that I'd need to scuff out further than the repair epoxy would go and I'd see the sanding marks? I've done quite a bit of searching both here and on the web in general and haven't found a good answer.

This is a new floor (I just screwed up)

Thanks for any tips

A little more info would help us out. Why does it need to be repaired? Bad prep on the floor? Is it peeling? Roller marks? Bubbles? Does it have color flakes? Did you use a primer? How many coats and what kind of system did you use?

Generally the repair area needs to be either sanded or ground down depending on the reason for the repair. Yes, you will need to overlap into the the good epoxy just like you would if you were repainting a section of wall in your home. If it's new floor then the repair will not be that obvious or you wont even see it at all depending on the type of system you installed. Pics help too

I have repaired a couple spots when tools have taken a chip our three out of the floor. I don't have a clear coat top so this might not apply.
I sanded down the area with 80 grit feathering it into the good epoxy. cleaned with D- Alcohol and repainted the areas with a small brush. Since the epoxy is thick I have a line between the repair and the old. Its not a big deal but it can be seen. I'm sure if I really cared that much I could sand it smooth and polish it up but I'm not that crazy. Also if I would have used the paint chips I'm positive I wouldn't have seen the repair.

Needs to be repaired because of hardner getting spilled on floor during curing process left 6-12 uncured spots dime to nickel in size, floor prep was good, not peeling, no roller marks, very tiny bubbles, no primer, single coat, and no clearcoat. It's one of the 100% solids systems used by others on the site. Not sure I feel a need to talk about the brand just yet.

I guess my question is, if I brush it into the existing coating how will it bond well?

In that case, just sand or grind the affected areas until all the soft material is removed, wipe well with denatured alcohol and then apply the touch up kit. You should be just fine and with luck it will barely be noticeable.

Thanks for the tip, I'll hopefully receive the touch up kit soon and get it finished up!
