Been in flooring buisness along time now
Weight of laminate is not much different vinyl.
Dont think laminate won't scratch it will.Drag something heavy over it or drop something heavy you will see it .
If you have a steady hand you can cut a piece out with a utility knife
Just take a section out .preferably cit on a grout line all the way around on your new piece.Put It over the bad piece .Tape it down and trace cut it.
MUST USE VINYL SEAM SEALER.
I see more people using vinyl planks now.Some are floating and some glued
very easy to do and holds up good and easy to repair
Good luck
