Fixing screw "mounds" post-paint
 
Looking for any alternatives/suggestions to fixing a problem I'm having in my living room.

After adding onto the home we drywalled, textured, and primed/painted the walls. Going into the room last night in low light (and indirect light) I noticed that I can see every single one of the screw holes in the drywall. It's only noticeable when light hits the wall from the side and creates the shadow. After checking the walls it appears the problem is on all the walls, and is pretty clearly from the person mudding the screwholes using WAY too much mud on them, and then not sanding them down flat. They aren't bad, just small bumps, but very clearly noticeable in the right light as they follow a distinguishable pattern.

The question is what to do now that they've been textured, primed, and painted. We took a small wall to try things with, easy enough to remove the texture, virtually impossible to sand down now that the primer/paint has bonded without ruining the wall (i.e. destroying the paper on the drywall).

Current process is removing the texture and basically skim-coating the wall in a very thin coat of mud. It's seemed to work out ok so far, but the wall is small. Looking for any alternatives to try out before deciding what to do with the larger walls in the room.

Who finished the drywall?:)

My parents. Mom put the mud on the screw holes. Dad did the seams and texturing.

They've done a lot of this kind of thing before, fortunately I took the work lights around the rest of the house and it appears to be isolated to the living room.

Sounds like a do-over.

How was the texture applied? What style is the texture?:)

The texture is just an orange peel style. Applied with a sprayer.

What exactly do you mean by a "do over"? So far I've heard suggestions for "do over" from pull down the drywall to doing exactly what we're doing now by skim-coating the wall and starting over at the texture. The skim coating seems to be looking ok, though we haven't gotten the wall finished yet. We just haven't run into a problem post-painting until now. Usually it's pre-texture and someone just gets yelled at to fix their mud job lol.

Do-over in the sense of redoing the mudding. Not removing so much of the existing mud so as to destroy the paper surface of the drywall.

Instead add more mud. Some texture muds may go on over the existing texture leaving a new texture that hides the screw mounds. Again try a small area first to see if that works. In some cases you need to put on a skim coat leaving a somewhat smooth surface for new texture mud, or leaving a smooth final surface if you changed your mind to prefer that.

By "do-over" I'm saying it isn't likely you can repair each individual fastener location without then going over the whole thing with texture. Skim-coating may be the answer but skim-coating will likely cause a bunch of ridges and ripples as the trowel jumps over the existing texture. Just don't know. A lot of sanding may then help the situation.

What do you see as the best way to approach it? You're there.:)

There is no reason I can see to remove all the drywall, that sounds crazy to me at this point.:)

We've been skim-coating it but removing the texture first (most of it anyways). It's a pretty light orange peel so the texture removal hasn't been too tough. My dad seems to think this method will work, and it appears to be going ok. This was the only idea we had though, told him I'd seek out some other opinions.

"Slap some more mud up on the wall" just seemed too simple to be the right way lol.
