Vent: My brother-in-law's comment about my garage floor paint job made me check the label
He was over last weekend helping me move a new workbench and casually said, 'That's a nice color, but did you use the right primer for the concrete?' I checked the can I bought from the hardware store and realized I'd used an interior wall primer, not a concrete bonding one. How long before this starts peeling, and what's the best way to strip it and start over?

Honestly, that's a rough spot to be in... did you clean and etch the concrete at all before you put that wall primer down? That step matters almost as much as the primer type. If you just rolled it onto a dirty floor, it might fail way faster.

What about the moisture level in the slab? Even a clean floor can push water up through the paint if it wasn't sealed right. That stuff needs to be bone dry for days before you even think about primer. A cheap plastic sheet test could have shown that.

Ugh, temperature swings are the real killer here. That wall primer won't expand and contract with the slab, so any big change will crack it apart. You're basically on borrowed time until the next cold snap.
