How to Apply Sheet Rock Compound
Sheetrock compound is available in three main types: taping, topping and all-purpose. Taping compound is used as the first coat when finishing drywall and topping compound is used for subsequent and the final coats. All-purpose compound can be used during all stages of the finishing process and is the type most commonly chosen. Make sure the drywall is ready for compound by ensuring that the screws are at the proper depth in the sheetrock and that the sheets have been properly fit together. Does this Spark an idea?

Tips & Warnings
Applying the drywall compound as smoothly as possible for thinner coats will help reduce sanding time and effort.
Sanding sheetrock produces dust. Close the doors and hang plastic from the ceiling to the floor in hallways to help eliminate the spread of the dust to other rooms. Open windows and exterior doors to improve ventilation. Never work in a fully enclosed area.
