I had to repair some areas of drywall, I am just wondering best way to prime and then paint the entire wall.
Should I just prime the spots with a brush, and then hit those spots with the new paint colour (brush or roller)?
Also how much ahead can I paint these areas before I roll on the paint.
Thanks for any info!

Welcome to the forums!

Mostly it's just a matter of whichever is easier, usually dependent on how big or many repairs need primed. There is a slight amount of roller stipple to be gained by rolling which might help the repairs blend in better. Sometimes it's best to apply a light texture to mimic multiple coats of roller stipple.

The primer or paint that is applied over the repairs needs to be dry prior to rolling the entire wall. How long that takes depends on how thick the coating is and drying conditions [temp and humidity] I have painted over small areas in as little as 15-20 minutes but it could need a couple of hours.

As Mark says, it's a judgment call. If the paint on the wall is decent and I only have a couple repairs, I spot prime. In my mind, if the spot priming hits about 20% of the surface, then I prime the whole thing but that's just a rule I made up myself.
