Once you have one section of the wall finished, move onto the next, repeating that same process. You will want to clean your blade in between sections.

Once the walls are totally dry, you can begin to apply additional coats. Give the final coat a full day to dry. Sand the drywall for that ultra smooth finish.

I hope those tips and insight proves to be helpful for your next big project! Hand sanding works just as well though! It just requires more time, with a bit more dust, and a lot more elbow grease.
