You may want to post this in the flooring section or have the Mods move it there. In the Flooring section there are a few flooring company specialist that can steer you on how to correct the problem. More than likely some self leveling material and then a coating over it.
I'm no specialist, but they will steer you in the right direction. You may want to post an overall pic of the floor and point out the low spots.
BTW...Welcome to GJ, and hope you stay around. Lot's of wisdom, ideas, car guys, contractors, and on and on that belong to the site. We can even diagnose your health for you if it gets to that point.
All kidding aside. Welcome. And ask the mods to move the thread or repost it in flooring.
