About me: You need to start with a completely smooth surface
area to wind up with completely painted walls or
woodwork. One professional tells PM that Sander
would be a more fitting job title than Painter
considering that he invests so much time pressing
sandpaper. Sanding levels outs spackle or
joint-compound patches and flattens ridges around
nail holes. Sanding also gets rid of burrs and
rough areas in your trim.
