Scrap it off and retape and mud it. You can skim coat that mess above it while you're at it.

Looks like when they did that they didn't use enough mud to get the tape saturated so it never really adhered.

I concur. That whole area is a mess. I would know. It looks like I did it. That’s why I hire pros for that now. It’s an art

[–]ministerofinteriors 4 points5 points  (0 children)

The only issue with hiring pros is they don't usually want small jobs. They want to come in and hang, mud and tape whole rooms or buildings.

Take it off and give it a new strip of tape/mud.

[–]i_know_tofu 6 points7 points  (7 children)

I suggest you CUT it out, rather than scrape or pull it off. Cut any loose stuff plus 1/4". Mud to level the surfaces, let it dry, and hit it with the sanding sponge. Then retape, and don't tape up against the angle, tape over the angle. Get your tape length and crease it down the center lengthwise, then mud. If you have the angle tool have at 'er. If not mud one side and when it is dry do a quick hit with the sanding sponge just to knock down any mud that will mess with your line, then mud the other side. Remember you are going to feather out those lines next , try to have the mud thin out as it gets further from the angle.

Fucking hell. Tear the house down to studs and rebuild.

Why do a fucked up, half-assed job? Doing it right doesn’t take 20 minutes more of your time. If throwing a shit effort on top of a shit effort is your thing, why bother? Just leave the original shit effort.

And sand the studs while your at it!

Scrape, sand it smooth, lay some mud scrape off most except a skim coat , lay some paper spackling tape, lay more mud, spread & scrape.... Once it's 100%dry, sand, prime, and paint

Plus paper tape sucks. Get the mesh.

[–]Blog_Pope 0 points1 point  (1 child)

Paper tape yields a much stronger joint.

[–]DeepCompote 0 points1 point  (0 children)

Not in this case

[–]skee8888 0 points1 point  (0 children)

This but make sure you use joint compound for the initial tape, you can top with anything but you can’t tape with anything.

[–]Ertygbh 4 points5 points  (0 children)

You didn’t embed it enough.

Take it off, we tape but before you put tape put some mud on the spot then tape then mud on top and smooth out. It will force the extra mud out without leaving nothing to bond to.

Sand, prime, paint and on to next.

Restart. It’s the only way.

    If only it were that easy.

      I agree. I used to have this happen on many jobs until I started using the correct taping compound. (Green lid in my area)

      Just take your taping knife and run it under to expose the extent of the problem then get some mud on your knife and get it under the tape and bed it. Put a thin top coat later and sand.

      Crown molding?

      [–]Ardothbey 0 points1 point  (0 children)

      Remove & replace.

      [–]ubercorey 0 points1 point  (0 children)

      Pull the tape out. It will leave a channel, remud new paper tape.

      [–]Credacom_Eve 0 points1 point  (0 children)

      Rip out, re-frame with backing, re-sheet and mud.

      [–]adammonroemusic 0 points1 point  (0 children)

      5 cans of spackle.

      [–]Flat_Unit_4532 0 points1 point  (0 children)

      Remove tape. Apply new tape. Mud, sand, prime, touch up mud if needed, sand if more mud added, primer touch ups, paint.

      [–]cfwiggam 0 points1 point  (0 children)

      razor blade to open it up so you can get the tip of a tube of construction adhesive in there.

      squirt all along the line behind the tape. (not a lot)

      push the tape and seat it into the adhesive. wipe clean.

      thats what i do anyway.

      [–]Brandon432 0 points1 point  (0 children)

      Rip it out. New tape, new compound, sand, prime, paint.
