Best way to seal a crack in a cement floor?

[VinceFox]

Ive got a metal shed on a concrete base, bot of which are solid. Ive also built u a cement runoff round the outside of the shed base at about ten degrees, but over time some cracks have formed in the cement. Not enough to make it weak, but the cracks do let water into the shed.

Is there a rubberised paint or something that i ca paint the cement angled bit with and stop the water ingress? If anyone's used something that they know works well i'd appreciate a nod in the right dorection.

I suggest a 2 pack epoxy filler, like this for instance. I've used it on concrete and it bonds really well.

Cheers, that looks like a possibility.
