To achieve a nice smooth finish, it's essential to sand to help prepare the area for painting application, by sanding you are removing imperfections (also known as pimples), creating a nice smooth finish while at the same time adding adhesion by developing small, rough ridges for the paint to stick to.

Use a pole sander. It will make it easier for walls. There always seem to be some rou spots that you’ll notice after you paint if you don’t sand.

Pole sander is not a person from Poland who does the work for you!
