here’s a great instruction manual, maybe you’ll find an answer here… its everything flooring…
great sight from the person above and great tips , go with it
There are sanders you can use that are far easier to use then the pros, belt floor sanders. I used to rent these floor orbital sanders that were about 14-16″ square the did a very good job. They were slower then the belt sanders, but were far more forgiving in the, “use” department. Home Depot used to have displays in their stores and rent them. Now they have Rental Stores that do it.
