Can I sand my own floors?
A 20 feet square room will take one person around five to eight hours, depending on your adeptness and the state of the floor, as a rule of thumb.
In you are having second thoughts GJP Floor Sanding employs a number of professionals that can do the job for you. You should only attempt to sand a floor if it’s made of a soft wood and is in something which you could comfortably class as reasonably restorable condition.
If you’re confident that you can do it yourself, rent a heavy duty sander which can be powered by the mains. Rent an edge sander too, and invest in ear protection.
