Crack fill product suggestion

[sixstring77]

Greetings, long time lurker but finally ready to get the garage floor done.

My wife tricked me into buying a new house because of the garage plans.

Inside floor dimension is 1300 sq ft. The back section is core floor with a storage room underneath. I'd like to fill the expansion joints and the other cracks that have appeared since the house was finished in May.

I've seen posts where people use Rustoleum Epoxyshield and I know epoxy coat and legacy industrial sell there own crack fillers.

If I end up going with say Legacy for my floor coating would the Rustoleum crack stuff cause issues?

I appreciate suggestions and the help I've read from others posts.

As long as you use a quality filler it will be fine.

Rustoleum crack filler is a 100% solids epoxy that cures hard as nails. It reminded me of JB weld when I used it recently. It's almost impossible to abrade by hand after 10 hours, so I scuffed it up with an orbital sander with 60 grit paper. An angle grinder would be better. According to Rustoleum you can just paint it (apply your epoxy of choice) after 8 hours, but it's so damn hard I highly recommend abrading it first.

PL has a caulking self-leveling concrete filler. I bought some to try, the only thing is it takes awhile to cure, days.
