How To Install A Floor In A Fishing Boat How Do I Install Hardwood On A Concrete Floor?

How do I install hardwood on a concrete floor? - how to install a floor in a fishing boat

The floor is concrete in my apartment and I want to install parquet flooring.
1 - I want something on the floor before installing the hardwood?
2 - Is there a need for nails, concrete forest?

I want to do the work itself (almost 700 square meters), you need to get hardwood.

Any tips? Thank you very much
