Can I use a different brand sandpaper or mesh on my Festool sander?
Yes. However, if the holes in the sandpaper do not align with the dust extraction holes on the sander pad then dust extraction performance will be impacted, this may lead to a shorter sandpaper life-span and potentially poorer results on teh surface of your job. Also some abrasives can have a different hook and loop connection velcro that can be detrimental to pad life.
