There's a school of thought that says this is bad concrete work and
nothing can fix it...

Floor paint works, but it's expensive to get one (chlorinated rubber
or epoxy) that can stabilise concrete. The affordable stuff won't.

A better sealer for concrete is waterglass (sodium silicate). This is
cheap(ish), if only you can find it. It's a bit obscure these days.
