We've got varnished pine floorboards in our lounge. They're in fairly good condition but I was thinking of staining them a darker colour, maybe walnut or rosewood.
Can I just apply the stain over the varnish or do I need to sand it first. If sanding is the way to go, would a light sand with a belt sander do the job or would I need to hire a floor sander and sand it right back to bare wood?
