There are two types refinishing methods: traditional and sandless (dustless) refinishing. For traditional refinishing, all the furniture has to be removed from the room and have a thorough dusting/sweeping done. If there are any cracks or scratches have to be filled to ensure a smooth surface after sanding. After that the sanding begins, which will remove old coats, scratches and stains to your hardwood floor. Next, we will vacuum up all the sand. Lastly, a stain or sealer is applied to the wood.
Dustless sanding is recommended for floors that don't have deep scratches or heavily damaged wood. It's also not 100 percent sandless. This method is less expensive and doesn't take as long to complete (typically).
