How big of imperfections can you float out of ceiling
Posted on 2/10/20 at 1:08 pm
Posted on 2/10/20 at 1:08 pm
So I recently scrapped my popcorn ceiling in my living room, but when I got the the last 1/3rd of the room, I discovered it is one big patch. The put a ton of mud up to apparently repair a water leak and the mud won't come off, so that area is raise about 1/8th of an inch from the rest of the ceiling. Is it possible to float this out with mud so it won't be noticible after I smooth and paint the ceilings? My other option is to cut the area out and putup fresh drywall, but will be more effort

Chances are if scraped, then there are other imperfections on your ceiling albeit not as severe as the patched area, that will likely get revealed once finished or take a lot of labor to get perfectly smooth. IMO, and it's what we did to ours, is to just have an orange peel texture applied to the already-scraped ceiling... orange peel looks effectively smooth and is still leaps and bounds better looking than popcorn. A good drywall person should be able to blend that patch in with the surrounding ceiling. If you want it to be perfectly smooth, better to just rip out the rock and start over, or put new rock over it.

How high is the ceiling and how likely is someone to look at it? If you are asking if you are on a ladder and looking down the ceiling and are an experienced drywall person, then yes you will be able to tell.
If your neighbor Betty comes in and sees your house then no its not likely she will see a minor hump on a 12 foot ceiling.
I would say it depends on how picky of a person YOU are OP. Worst part about working on your own home is knowing exactly where all of your frick ups are and having them slap you in the face everytime you see them.
General rule of thumb that I've been taught is the best fix you can do is about two trowels wide. So you even it out with one trowel down the middle and then skim about a half trowel on either side of that.

Or here's another option, sand it.

We did a fairly light knock down after removing popcorn. Looks exponentially better than the half bath i did trying to make it smooth. The imperfections drive me crazy and i'll be doing knockdown in there too soon to cover them up.

Yeah it makes a huge dust storm, but an electrical hand held sander like an orbital sander with a fine grit knocks through drywall mud with a quickness. You gotta be careful it goes through it so quick. So if its just heavy mud, sanding it down is definitely an option.

Yea, I thought about sanding it, but I feel like replacing the drywall would be alot easier. I may be wrong, but it's a 8x14' area, and I feel like sanding that would be alot more work than replacing.
And for whoever asked, it's 9' ceilings

You'll also have to mud and then sand the area you replace .. so the option is yours

Buy a cheap one at Walmart and buy the extended warranty. The dust will burn up the motor. Been there, done it twice. I hook up a Shop Vac that collects about 90% of the dust.
Using the vacuum is the reason the dust burns up the motor. I bought pool hose from a hardware store that cost about $1 per foot. Just tape everything together. 
Another thing. One has to wash out the fine filter of the Shop Vac after about an hour sanding.

That's why I was leaning towards just floating out mud from the repair. Figured that would be the easiest.
Edit: I feel like I'm coming off argumentative, and I'm really not trying to be, as I have never done this before. But sanding off a 1/8" layer of mud over an 8x14 area, and then trying to make that all match seems like way more work than just putting up fresh drywall and sanding down the seams and scratch coat

Skimcoat the entire ceiling to fix any damaged spots from scraping. Then sand everything smooth and level with a wide sanding screen on a pole. It will make a mess, but the only way to get a good smooth consistently sanded finish is to use the largest rectangle sanding screen you can handle. You may have to spend some extra time on the repaired part first to try and get it close to level with the rest of the ceiling.
FYI, if you have any spots that ripped the drywall face paper and the brown paper is showing the best way to keep it from bubbling when you patch or skim that area is to paint it first with some PVA primer.

No way. An orbital sander and you can have it all sanded in 30 minutes. Drywall unpainted is a shitty building material outside of being cosmetically manipulated, it sands super easy. Especially if all you need to do is make it skimmable. You don't need to sand the entire area.
You just take the orbital to the lipped area, then take the drywall sander (large sander on a stick) to smooth it all over. Then skim the entire thing. I'm by no means a drywall pro, but that's what I'd do.

I would try hard as hell to work with the patch that is already there, because it will be the easiest option. You also do not have to sand it all off, just all to the same or relatively same height. If you skimcoat the whole ceiling, you will probably end up even with that spot anyway.

How high is the ceiling
If he has popcorn ceiling, my money is that it's 8' high and would be noticeable. Of course, I can be wrong, but it seems like 95% of the houses I've been in with popcorn ceiling is a ranch style house with 8' ceiling except it's vaulted in the living room.

It's 9' ceilings. I'm going to try sanding it first. I've got everything out of the room so I will get to sanding tomorrow. Thanks for the advice guys, I'll let you know how it turns out

Wet sanding is another option that might help feather it into the rest of the area. That would eliminate the dust that is going to get everywhere no matter what you do by screen sanding.

Sanded, mudded, and resanded over the past 2 days. Just put on a coat of primer. It definitely looks better than before, and can't really see the transition between the repaired portion and the drywall.
Still see alot of other imperfections around the room that need to be fixed. Hopefully between some mud, and light sanding I can fix most of them.
Any opinions on a good thick ceiling paint that will cover some of the imperfections?

You have a lot more patience than myself. I would have just slapped a layer of drywall over the popcorn

Getting off 2/3rds of the popcorn was a breeze, it was the last 1/3rd where they had repaired that sucked
