Laminant over concrete floor that isn't flat

Converting part of my garage to a home office. I am nearing the flooring part and checked for level today. Using a 7' level I discovered the floor to be wavey from front to back. The gaps seem to be less than 1/4" at most. What are my options since I already have the drywall done and this is a 100 sq ft room?

Use a leveling compound. Latacrete makes one as do others. I've used the Latacrete brand many times.

Laminant over concrete floor that isn't flat

Most laminate manufactures recommend the floor to be flat and smooth within 3/16" over a 10' span. Dips or variations in the sub floor greater than 3/16" over a 10' span need to be filled. There are several floor leveling compounds that can be used for this. One of my favorites is Ardex Feather Finish.
