Let the mud set until hard and shave off whatsoever ridges in the surface using an upwards stroke with the joint knife. Sand any other crude spots using medium sandpaper and wipe the grit abroad with a damp rag. If the surface has deep scratches or pits in it, utilise another coat of setting compound. If it is fairly smooth with only small flaws, keep to the final coat.

Utilise a Finish Coat
