The garage floor epoxy paint is very slippery when it gets wet. Very slippery.
I'd recommend putting down commercial grade carpet tiles. Inside the basement I use those 24 x 24 black interlocking foam tiles. They double as "gym" workout pads.
No prep needed for either. Just lay 'em down and you can trim them with a pair of heavy duty shears or even just a "utility knife" aka a "box cutter".
