If you've ever looked closely at your floor, you may have noticed small plastic discs scattered about. These are called floor plugs, and they serve an important purpose. Floor plugs are inserted into the holes left behind by nails or screws so that they can be covered up. This gives your floor a clean, finished look. Without floor plugs, your floor would be full of tiny holes that would collect dirt and dust. Floor plugs come in different sizes to fit the different size holes left behind by nails and screws. They're usually made of plastic, but sometimes metal or rubber is used. To install a floor plug, simply push it into the hole until it's flush with the surface of the floor. That's all there is to it! So next time you're admiring your floors, take a closer look at those small plastic discs - they play an important role in keeping your floors looking neat and tidy.
