Can we install a prefinished hardwood floor and then put a coat of polyurethane over it, to seal all the cracks?

Q: Can we install a prefinished hardwood floor and then put a coat of polyurethane over it, to seal all the cracks? Will it adhere to the prefinished hardwood?

A: No. If you don’t like the bevelled edges get square edge site finished which is what I generally recommend. Pre-finished floors will end up costing more in the end. The bevels are an issue.
