Wooden floor revarnishing

Re-varnish your floor. Degrease and then rub down with the grain or use fine abrasive paper on a random orbital sander. Then give three coats of Ronseal heavy duty clear gloss floor varnish. (Not the water based one) Apply with a small short haired varnish roller. Ignore the small bubbles as these disappear after a few minutes. You will be amazed at the finish, as good as any BMW. Also if applied in warm conditions you can have the job done in a day.
