Whether you're doing some rough or fine sanding, Porter-Cable has the sandpaper you need. We have a great selection of convenient rolls varying from 80 to 220 grit. Porter Cable has implemented many features into their sandpaper to help make it more efficient and long lasting. A resin coating helps resist against the damaging consequences of heat and humidity while at the same time prevents clogging. They also have pressure sensitive adhesive on the back so that it holds securely while you are using a palm grip sander.
