Frequently Asked Questions
Wood floor sanding is often done in 3 stages or "cuts" : first cut, second cut and final cut. The lowest grits, 12 grit through 36 grit, are selected for the first cut where you have to take off layers of old wood floor finish. If you have new wood floors with no finish on them, you can usually start with 40 grit abrasives as your first cut. For second cut, most contractors use 50 or 60 grit. For the final cut, most contractors finish with 80 grit or 100 grit with 100 grit being the most common choice. 120 grit can be used for the final cut depending on the project but it is used least often. Stopping the sanding process at 100 grit is desireable if staining the wood floor as it leaves the wood grain open enough for good absorption or penetration of stain. For a natural wood floor, where you don't intend to stain, either 100 grit or 120 grit can be used for the final cut to achieve the smoothest result.

Most rental stores offer a variety of machines. Please click on the links below for pictures. For edgers, you'll likely use either the American Sanders EZ-E or the American Sanders (Clarke) Super 7R. For either of these, you would use the 7" Disc with a 7/8" Hole. For a drum sander, you'll likely use an American Sanders EZ-8 which would use the 8" x 19" Belts.
Silicon carbide works great for sanding raw wood and removing old coatings. But it wears down quickly and can fracture inconsistently. It also sheds more during its initial use.
Aluminum oxide is a blocky grain that wears down quickly. However, it leaves a fine, consistent scratch pattern.
Zirconia alumina is a micro-fracturing grain, so it lasts longer than silicon carbide. It's engineered, so it's more consistent in size and scratch too.
Ceramic alumina is engineered from sub-micron crystals of aluminum oxide. They're the sharpest and longest lasting of the grains. They are very consistent in shape and size.
