I am about to move into a 15-year old house. Under the carpets are nice-looking pale wooden boards, which I'd like to use as my floors. The boards are in good condition, and have never been stained or varnished. Do I still need to sand the boards before applying a varnish?
If so, I presume the job would be a bit easier and quicker than sanding down old boards to remove a previous finish? How long might it take a complete beginner to sand the ground floor (sitting room 5m X 3m, study
3m X 4m, dining room 3m X 4m, entrance hall plus corridor) using sanding machines?thanks, Russell
