I removed my old door casing during my kitchen floor tile project so I could install a different style of casing. The new casing is the same width as the old.
The issue is that even though I cut the caulk between the old casing and the wall, there was still a bead of caulk left on the drywall, which was pretty much impossible to remove without tearing the drywall paper at least somewhat. I had the same issue in my bathroom and my son's bedroom, where I also replaced door casing in the same fashion.
This door is particularly bad because after removing the casing, I found that the door frame was installed with no shims whatsoever. So after shimming and truing up the frame, I ended up with about 1/2" more gap between the back of the frame and the wall stud. Installing the trim with the same reveal on the frame (had to use the same reveal to have enough room to shoot brads along the edge) left about 1/2" or more of the unfinished and/or torn-face drywall exposed.
In the other rooms I tried using spackle compound and sanding it, but always ended up with a noticeable difference in texture between the originally painted areas and the spackled areas after applying the new paint. Does anyone have any suggestions about what to do here? I plan on replacing all the door casing in the entire rest of the house as time and money allows, and I'd like to have a nice wall finish around them if I can get it.
