Drywall Corner and Ceiling Skim Coat
Drywall corner question. I am going to remove and replace drywall to a section with an existing outer corner. How do I perform this without damaging the drywall on the existing corner? The drywall to be removed is under a steel drywall corner which is nailed.

Ceiling Skim Coat question. I have scraped the ceiling in my kitchen and an adjoining hallway to remove the crows foot texture. The ceiling is approximately 20 x 15 feet. Now I am ready to skim coat. I will be prepping the ceiling first with Kilz to seal the scrapped area. How I do perform the skim coat to ensure a even surface?

I will be using the light taping compound in the bucket with the blue lid that I purchased from Home Depot. I have a 12" inch finishing trowel and a 12" taping knife.

Any advice would be appreciated.

if you dont want to re-mud the outside corner and the wall you are working on is good up to that point, just cut out the drywall up to the last stud before the outside corner.

You just need to make sure you have good backing for the new sheet of drywall. Mud the butt joint and leave the corner alone/

What have I done,

Thanks for the reply. Unfortunately I can't do that. You see, half of the drywall is covered with that crappy Z-brick all the way to the corner. We are having our kitchen remodeled and the wife wants a tile backsplash where the z-brick is now. So I have to remove the old drywall and reinstalled new.

Help With Your Drywall

Has the drywall actually failed or is it that removing the Z-brick is going to be difficult and leave the surface of the drywall rough that you are concerned with?

You can use a 6" taping knife to get under the Z-brick and remove is then use a good rough drywall sealer, sand it a bit to smooth and then skim coat with the 12" knife. That way you get to keep the corner in place and the drywall removal and replacement is eliminated.

Also with the ceiling use the 12"knife with a thin coat and when it is all dry you will sand it smooth. The finish trowel could be used if you are accustomed to it but the learning curve may slow you down.

Removing the Zbrick is a real pain in the butt. I tried, but the Zbrick cracks in places and you can't get under it to scrape off without gouging the drywall. Removing and replacing is much easier. We are going to replace the cabinets and I will have full unrestricted access to the walls for replacement.

I got it on the pain factor
I can understand the the toughness of that brick. I'm wondering how many corners you are talking about and why you wouldn't just rip off the corner bead, replace all the needed drywall and then install a new corner bead. It is a lot easier than you may think to replace. The part around the corner that is going to remain is easy enough to match up to by placing the new corner bead right back in the slot the old one came out of and mudding it in place.

Sometimes the application of those brick fascias aren't as strong as you mentioned. That's why I always go for pealing them off first.

under it to scrape off without gouging the drywall
Not sure how they are fastened,buy have you tried a flatbar with a piec of wood between the bar and the drywall?
