How to smooth a grooved, rough garage floor?

Hello,

in my garage there is a 3-year-old very rough concrete floor. It has many grooves about 5mm-10mm deep, as if the previous owner wanted to increase grip for the tires.

I would like to have an attractive smooth surface.

Do you have any tips on how I can do that? For cost reasons, I would also like to do it myself.

Thanks!
Marius

Hm, why would you need grip in the garage? Picture(s) please.

Here are the requested photos

I can only think of flowable screed / leveling compound. Or does the garage have a slope?

Otherwise: there are people who tile the garage.

Thank you for your answer. I am concerned that leveling compound would not withstand a jack, motorcycle stand, or axle stands. Or do you see it differently? What could I put on the leveling compound to make it more resistant? PVC covering? Tiles are unfortunately out of the question for financial and aesthetic reasons. By the way, the garage is 54 sqm.

I would not recommend something completely smooth. When it is wet, it becomes slippery.
[Ausgleichsmasse], [Industriebodenbeschichtung] is best with grit to prevent it from being slippery.
