Drywall Prep (Existing butts to new)
I recently added some greenboard that butts up to existing drywall.
The existing drywall has semi-gloss paint on it. How do I prep this? Light sand? I don't want the mudd to start lifting or cracking. |

Just use Sheetrock Brand Durabond Setting Type Joint Compound for appling the tape and Sheetrock Brand Easy Sand Setting Type Joint Compound to coat it...Skim it with Regular joint compound and sand...HTH... |

This may spark some outrage, but I saw an oldtimer do this: he cut about a 4' piece of scrap drywall about 8" wide and cemented it to the back of the sheet already in place with mud. After everything had set up well, he tapered the butt edge 6" or so just to the gypsum on the butt edge. Did the same thing to new sheet butt edge. Mud was applied to reinforcing patch on the back and the new sheet installed. Next came tape and mud and the usual finishing. The result was a dead flat joint, and the reason given was that it was critically close to the lighting, and would look bad, conventionally done. Extra labor a half hour. Appearance some years later, perfect. Only downside is a little more dust than usual from the disc sander. I'm adding this to my problem solving tricks list. Joe |
