Hi Y/A, I have to repair some old ugly seams that have been patched badly, painted over twice and are now cracking as well, you know, where rooms are divided at the ceiling? What's the best way to clean those up without knocking them out and doing it <right> over? I have one, fairly long one..5 ft.
Cut old tape and mud out. You can use either sticky mesh tape, or paper tape. Mesh tape goes down before mud, paper after skim coat of mud. Soak paper tape in water before use to prevent pealing. Try to make mud as smooth as possible, to reduce sanding. 3 coats, sanding between coats, or until smooth.
it extremely is why you notice a super sort of ceilings with popcorn texture. The acoustic texture hides the failings. confident ceilings are greater solid reason you're working over head. you need to use a 12 vast knife on the seams. The topping compound could be a minimum of 12 or greater inches huge. this would feather out the seam. a superb dry wall-er would desire to try this authentic away and he does no longer cost you plenty. Spend some greater dollars and hire out, you already did the complicated area. good good fortune.
anytime you repair drywall you need tape i like fiberglass tape for repairs and durabond its harder and drys faster just make sure you get any lose off then patch it buy bedding the tape in the mud or drywall compond then let dry apply 2 more coats then sand prime and repaint use a bigger knife each coat to widen the coats and wipe it smooth not leaving a edge thats the sanding that will take place good luck
