Levelling a Garage Floor

[TheArchitect]

Looked around a bit and decided once I get a moment I'd like to level the garage floor to make it easier to jack the cars and nicer to work on. It’s currently like a ribbed concrete finish (1980s build). Am I correct in thinking a coat or two of PVA to help act as a damp barrier and then coating with something like Cempolay Ultra will be the correct way to go?

How easy it is to apply the Cempolay Ultra for someone who has never done it before? It’s a double garage so a decent size floor space.
Is it relatively self levelling or do I need da Vinci like hands to get a good finish?

My double garage is exactly the same. I plan on using this stuff when I get round to it:

Thanks I looked at that however its nearly double the price of cempolay ultra which makes a big difference.
