100-Grit Edger Disc, 6” or 7”
Use if you have a fir or maple floor and have sanded the middles of the floor with 80-grit on the drum sander.
100-grit edger discs are the item to use if you have a fir or maple floor and you have sanded the middles of the floor with 80-grit on the drum sander.
We rarely bother sanding to 100grit on the drum sander – drum sanders leave such a nice, parallel scratch that usually the 80-grit is well-camouflaged in the wood grain and almost indiscernible. But the edger leaves scratches that go against the grain, which are difficult to hide, and on maple and fir they tend to be even more visible. So, our insider tip is to skip 80 on the edger for those woods and jump straight to 100-grit.
The 100-grit is just strong enough to remove the scratch from the previous grit (60), but leaves a finer, shallower, less noticeable scratch.
