Over the past 30 years, parts of our concrete basement floor have undergone some wear (shocking, I know). There are no major cracks other than expansion joints, and no serious spalling. It's just exposed aggregate and a rough surface (1/16" or so depth variation) caused by foot traffic.
Is this something that I could "smooth over" with an epoxy floor repair compound? I'm ready to use an epoxy paint afterward to protect the entire surface, but that seems unlikely to smooth the rough areas.
I would suspect there is something seriously wrong with that concrete if foot traffic is wearing it out. I doubt any kind of top coating will stop the wear if it is that weak. Sounds like the top surface is spalling off from being cured improperly
The surface does seem improperly cured. I can scratch it in some places with a piece of hard plastic. However, the floor isn't otherwise failing in any obviously serious way - no cracking other than at the expansion joints, no major crumbling, etc. It's just wearing in high traffic areas over time.
Oh well. What can't be cured (heh) must be endured.
