Patching small cracks in concrete

[ae82gtm]

Hello all,

I'm about to epoxy-coat my garage floor, and though only 7 months old, the first winter was unkind to my new floor.
There is some chipping by the expansion joints... that's easy, I know what to do (fill up).

However for these small cracks that are not very deep (~1 mm, see pic), what should I do? Is the epoxy-coat thick enough to cover this up? Or should I patch up?

Thanks!

I still patch it up with a concrete based patch like webcrete and use latex with water to mix it. I didn't do one hairline crack in my garage and I can still see the crack. Better safe than having to back up to fill something.

I would suggest using a 100% solids surfacing epoxy. It looks like you still need to prep your floor though, will you be grinding or doing an acid etch?

That's correct, the floor isn't prepped yet. I plan on only doing acid etch.
Thanks for the suggestion regarding what type of patch to use. I believe the Rustoleum epoxy concrete patch will work.
