The next step was skim-coating. Skim-coating fills in all of the small irregularities, nicks, scratches, cracks, etc., leaving a nice smooth surface. For this process, we just used the pre-mixed drywall compound. To skim-coat, use a wide drywall knife (the wider, the better) and apply a thin coat of the drywall compound to the entire wall. Once it is dry, use a drywall sander to smooth it all down.
