Q: When will I need to sand and refinish my floor?

        A floor that is properly maintained should never need to be sanded and 
        refinished. Watch for the signs! When your floor has lost its original shine, you 
        may only need what the industry calls a screen and re-coat (the application of 
        one or two coats ).  This is simpler than a sand and refinish. If your floor has 
        deep scratches, dents, and areas where the dirt has been ground into the open 
        grain of  the floor - or if you wish to change the color - it's time to have your 
        floor sanded and refinished.

Q: How many times can I sand my floor?

        This depends on what kind of wood you have and how bad the damage 
        is that you're trying to remove. Have a professional inspect your floor.

Q: What should I do when my floors starts looking dull?

        Start by giving it a good cleaning. If the result is not satisfactory, 
        you may be ready to have your floor screened and re-coated 
        (i.e. the application of one or two coats of  finish.)
