You should vacuum the entire floor frequently with a soft hardwood floor attachment which is especially important if you have prefinished hardwood flooring because the bevels collect dirt quickly.
Apply extra coat on prefinished hardwood.
In general factory finishes and comparable coatings you apply by site finishing such as polyurethane take little maintenance.
I read the question about the differences between laminate hardwood and pre finished.
Lightly sand with a dull 120 to 150 grit abrasive screen or 2 steel wool under a heavy floor buffer.
Keep the floor clean use furniture floor protectors and expect to apply a new coat of polyurethane on the floor every five to.
Whether you can seal a prefinished floor with polyurethane depends on your circumstances and the condition of the hardwood floor.
Difficult to repair if pre finished hardwood flooring gets scratched or dented during installation you have no option but to replace the entire floorboard.
There is no way you can ever manually duplicate the factory coating.
As noted the prefinished allows for the possibility of spills going through the slats.
Can prefinished hardwood be sealed to avoid this problem.
The urethane used in sealing wood surfaces is more commonly known as polyurethane.
Forget the notion of trying to fill sand and re seal with your own coating.
Prefinished floors offer serious challenges to re coating because of the type.
It cannot be done.
Traditionally hardwood flooring was always installed as unfinished planks that were then stained and finished with a protective surface layer right on the worksite.
