This 4th of July, I tried to refinish a wood floor that had about 20
layers of paint dating from 1890. That was wrong of me, so wrong, and
I promise never to do it again.
This photo shows one of the edger's sanding disks. In approximately 20 seconds, the in edger produced enough friction-generated heat to melt the aforementioned layers of floor paint, thoroughly coating the abrasive surface of the sanding disk and rendering it useless.
If this happens 15 times in rapid succession, it can cause otherwise optimistic and capable adults to weep hopelessly into a wad of painters rags.
I do not recommend this activity.
