Can prefinished hardwood be sealed?

Q: I read the question about the differences between laminate, hardwood and pre-finished. As noted, the prefinished allows for the possibility of spills going through the slats. Can prefinished hardwood be sealed to avoid this problem?

A: No. Prefinished floors offer serious challenges to re coating because of the type of finish and the bevel edges. If you want a floor that is coated over the entire surface, have a site finished floor.
