I am going to sand and refinish my maple floor in an 80 year old house. The last time I used a drum sander, but I recently saw a Varathan dustless ROS for rent. Anybody use this machine or heard about it? Is it any good?

Also, Minwax or Varathan poly for the floor?

The circle sanders are not as aggressive and it is easier to produce a flat sanding job without gouging the floor. Drum sanders definitely take more of a skilled hand to operate and achieve a nice looking floor. The vac works OK for keeping the dust under control.

I have used both Minwax and Varathan with great results. The flooring companies use a catalyzed finish.

As a remodeling contractor I have finished 6 myself. It is such hard labor I decided to hire it out. I have advised homeowners that call me to do the same. At least half start it and then call someone to finish, the other half wish they had called a finishing company.

The finishing companies will come in with a crew and sand everything in one day. They will apply coats over the next 2 days and then it’s done.

Well, almost, the shoe moulding will still need to be applied and you can do that yourself or have them do it too.

A flat finish is what I desire out of this. I still have some very minor gouges from the drum last time, but mostly cupped boards now.

Thanks for the info. If they are about the same, I think I’ll use the Varathan this time, the Minwax just didn’t seem to hold up as I expected.

BTW, at less than 200 sq. ft. the sanding for me is likely to be finished in under 3 hours + another hour or so to scrape and sand the edges.

There you go.

I am surprised the Minwax did not hold up. Was there a separation issue due to wax residue on the floor?

This is one of the problems that I have seen before.

How old is the floor, and how many times has it been sanded? Cupped boards may be due to them being too thin because of prior sandings.

The floor is 80 yrs. The cupping is not real serious and only in places where the finish has worn off, maybe due to moisture getting in there. This will be the second sanding on the floor and I can see a cross section in a few places along the edge, there seems to be plenty of material to sand.

Like Todd said the ROS style sanders are not very aggressive so they take a LOT longer to get the job done.
