The new disk sander looks pretty fool proof, and simple to use.
Has anyone on this forum had experience w/ one of these new sanders? How did it perform compared to the traditional drum sander? I went to Home Depot today to ask the guys there, and none of the guys in the rental store had experience w/ using one. Any information would be greatly appreciated! Thanks
If the floors have real thick, old finish, you can forget using the new style disk sander. Even the drum sander with an open grit (like 20) sandpaper will have it's work cut out for it. If the floor has a thin worn finish, you could use the disk sander. As indicated in previous replies, these sanders are pretty fool-proof, and easy to use compared to drum sanders.
Do you want to change the color of the floors, or think you'll need to stain the floors? If not, you may be able to just do a light sanding of the finish with a random orbit floor sander, and apply a new finish coat. Though you need to use a finish coat compatible with what's already on the floors.
BTW if you stain the floors, never use a water based stain!!! Water based stains dry very fast!!! When working on large areas, you will most certainly end up with lap marks if you use a water-based stain. When I refinished my floors I used an oil-based stain and a water-borne poly that could be applied over a oil-based stain after a certain amount of time. I decided on a water-based poly, because it dries/cures faster, and therefore you can move your furnature in faster. Though one have to put on twice the amount of coats, because it goes on thinnner.
