Removing Drywall Paint Primer?
Question:I tore down the old plaster walls in my soon to be daughters room and then insluated and put up drywall. After 3 coats of join compound and sanding I started to prime the walls. After doing so I see areas where my sanding just didnt' cut it. It is very hard to sand the primer off is there a better way to get rid of it and then re-sand/re-prime?
Answers:
Use a power sander (orbital would give you the most control), with 100 grit sandpaper.. this should cut thru the primer in short order, and let you start working on the mud. For a smoother finish, swap to finer grit paper, 180 for example. By this time you should be back to the drywall screens for sanding.
You can rent a special drywall sander that has a vacuum attachment... this helps cut down on the dust in the air very well. (well worth the cost of renting one)

Maybe try a paint thinner?
I am doing the same project in my home. I have only had to resand to get below the primer. It just took extra sanding.
No, but you can just mud over those areas again, right over the primer.
Oops is a good paint remover, and does a good job available at local hardware store
I agree with mudding back over it. Wont hurt a thing . Try thinning the mudd a bit. Thin coats are much easier to sand. Take your time. Dont rush it.
It's not necessary to remove the primer to re-coat the places you need to touch-up. Simply make the necessary repairs and sand, then reprime. Priming actually helps you to find these areas as they don't often show up prior to priming.
You need a small motorized sander! It will go much faster!
No need to remove the primer. Just a waste of your time. Joint compound will adhere to it. Use a topping compound for your last coat or two for a smoother finish. Drywall repairs should never be rushed. If you take your time & apply the necessary coats and sand prperly between them, you will never see where the repair was done.
