About me: You have to begin with a perfectly smooth surface
to end up with perfectly painted walls or
woodwork. One pro tells PM that Sander would be a
more fitting job title than Painter given that he
spends so much time pressing sandpaper. Sanding
levels outs spackle or joint-compound patches and
flattens ridges around nail holes. Sanding also
eliminates burrs and rough spots in your trim.
