Wood stain MUST penetrate the grain of the wood or it doesn't color. clear coats like Varnish or Urethaneare designed to seal over the stain "color" & keep the wood from being "stained" by all the dirt & spills it endures over time. If you don't sand the old finish off evenly it will keep the new stain from penetrating and it will also allow the stain to penetrate in areas where the old varnish was worn or damaged but not in others making the new stain blotchy & uneven. A good quality urethane is far better and easier to apply than Varnish. .
