Fixing a drywall ceiling after it is primed/painted?

Question

After painting, we noticed our drywall ceiling looks bad. You can see where the joint has been plastered because there is a bulge there. My boyfriend installed the ceiling himself and put the cut edge facing the middle of the ceiling instead of the angled edge. Does anyone have any good ideas on how to fix it?

The paint I used is CIL pink ceiling paint that turns white when dried. It has a non-glare matte finish. (For the record, the pink tint isn't that dark, so its still hard tell where you painted when painting over white primer. Hate painting ceilings, ick.)

Answer 1

the only way to fix that is to feather out the drywall plaster. You will have to layer it or feather it outwards until you get a smooth finish. Probably take quite a few applications and sanding in between each one.

Answer 2

This sounds crappy but it works... I used to do drywall with my dad and we fixed tons of problems like this...

You need a knife, cut along where the bump is... (think of it as cutting out the bump) then sand the area some to even out the edges... dust out the area. Then use more drywall mud and fill in the hole... if it won't stay in try covering it with pieces of drywall tape... let it dry really really good... then sand the area smooth and cover with the same paint you used on the rest of the ceiling.

It may end up with a hairline crack after some years, the only way to avoid that is to redo the whole ceiling without the mess up. Because that mess up is still under the drywall mud... if it shifts over the years you may have to refix again.

If you have any questions... you can email me.

The only way to really eliminate the seam is too feather it out with plaster until the seam appears to go away. In your case (because the cut is at the seam) You're really just making the bump spread out over a greater distance so your eye doesn't see it. You will want to use a finsih plaster and spread it the seam a minimum of 14" but most likely you'll need to go to 21". Buy a good flat drywall knife with a 14" blade to do it properly and reduce the amount of sanding.

Apply a texture to your ceiling. The easiest would be "popcorn" this may help hide the defects.
Otherwise, you'll have to try to sand down the joint and maybe float a little more plaster out from the joint to make the transition from the joint to the drywall more gradual.

Answer 5

you could attempt the product I surely have a link to on the top of this, it is by utilising USG and is a primer that has a small volume of joint compound interior the primer so once you prepare it, there's a greater useful hide making each and all the ceiling have the joint compound visual attraction earlier portray, yet i do no longer think of it is going to artwork for you presently. My suggestion is the use 220 grit sandpaper and sand the offending joint to tough up the paint. blend a small volume of your ceiling paint with some joint compound to make a slurry and prepare countless gentle coats to even out the version until eventually your eyes ( and arms as you run over it) do no longer detect a distinction. Joint education is in simple terms a count of reducing the version between compound and ceiling. while sanding be careful you don't recover from excited revealing the paper reinforcing tape.

Answer 6

It is possible to camouflage the area by applying a "Textured" finish to the ceiling. That is why "Textured ceilings were developed. It is very difficult even for "Professional" Tapers to completely hide the seams on a drywall ceiling. Without texturing all imperfections are visible.

Answer 7

There's no problem with applying joint compound over dried paint. I've done it many times. It sounds like the joints are visible, so this time use a wider trowel so you can feather out the joints farther.

Answer 8

try using a flat paint . the more gloss a paint has the more imperfections will show
