Levelling garage floor

[acsimpson]

My garage floor is uneven. I would ideally like it to have a gently run from back to front but it currently has a few holes (about 1cm deep and a run from the door inward for the 1st quarter of the length.

At the back is a work surface with washing machine under it although I can raise the surface if required it would be extra work.

In the middle is a door with step down (currently about 25cm)

At the front the garage door has a rubber seal which meets the existing concrete and would be hard to adjust for a different height.

Can someone please advise me if there is anyway I can skim the surface of the floor to provide the run off I am looking for or if I would have to redo the whole slab?

If the only option to fix the gradient is redoing the slab I will have to live with it, in which case what would be a good product to smooth the surface before painting or other coat is applied?

Thanks in advance for all your help.

I'm not aware of an easy answer to get you your desired finish so the best solution might just be to use a self levelling compound to fill your patches. You can purchase different types of "latex" as we (tilers) call it and I am aware that Wickes sell a variety according to the thickness you need to apply so choose carefully.
