Hello lilmooses.  Welcome to the Community!

 

Yes, but the prep is no big deal.

 

So your walls have new drywall installed, and the seams have been taped and mudded.  I assume that all the sanding has been done to make the wall completely smooth.

 

That leaves this simple prep work:

You need to remove as much of the sanding dust as possible.  Some use a brush like this from the top down to knock the dust to the floor and then use a wet/dry vac to clean the whole room.

Others will just use the brush attachment on the vac to go over the walls.

Once the dust is gone you will want to prime the drywall.  The least expensive way is to use a PVA primer sealer, but many good primer options exist.  See a paint specialist at your local Home Depot store for more on this.  

 

So that's it.  Get the dust out and use a primer.

 

Some folks will use a hand or pole sander and 150-180 grit paper on the primed walls after the primer has had a couple of days to dry.  This will provide a smoother paint finish, but is also more of something only a perfectionist would bother to do.

 

Is this what you are looking for?

 

Chris.
