Proper prep work and the right primer are the keys to success
The keys to successfully painting drywall, are proper preparation, and use of the right primer to attain professional-looking results.
After installing new drywall, do the following steps as laid out for you here, you'll get the results you want.
Prepare The Surface
Visually inspect the newly installed drywall to see if any holes or scratches occurred during installation. If so, repair with your favorite filler, let dry, and sand smooth.Apply caulk where needed.
For example: If you installed new baseboard an/or trimwork on top of the drywall, you'll need to caulk, or fill-in the resulting cracks and gaps after installation. This will be followed by painting.*

OR....Apply caulk to wall corners or ceiling joints if you see any irregularities that you might need to address.
Time To Prime The Walls
Once you've completed your prep stage, you're ready to apply primer to the drywall.Spread out all drop cloths to protect flooring.Use only high quality latex primer as this will ensure a solid seal to the surface of the drywall, and a good base on which to apply your finish coat.
Follow the same procedure to prime the walls (when painting drywall) as you would to paint walls. It's exactly the same steps.Always sand primed drywall (especially when painting drywall) because when primer is applied dust and paper fibers on the surface of the drywall itself, can be raised. Just use "Fine" grade sand paper to sand the drywall smooth.
For more information, see my page on sanding after applying primer.Wipe walls off with rag to remove dust.
Apply Finish Coat(s)
This is the step where you apply the finish coats to the walls.Apply your desired finish coating. You may have to paint more than one coat, depending on not only the quality of the paint, but the color as well. Dark, vivid colors usually require more coats.
(hint- you might want to consider using a tintable primer for dark colors)
Again, for detailed information, please reference my page on painting walls.
