Is it possible to floor with laminate when you have an uneven floor?
It's possible to install it and have it look decent, but in time the space under some of the flooring will result in visible cracks and seperations. If you're dead set on laminate, just start by using a concrete based floor leveler to fill in just the low spots. A decent home center will have everything you need, the concrete leveler and additive runs about $20 and $8 respectively.
You could probs make it work so long as its not to extreme
