Hi everyone. I'm new.

I live in a condo. I originally started to paint the stucco ceiling with ceiling paint and of course the "popcorn" fell off in large patches as I moved on. (I didn't know water anything can touch it...I swear). So I wet the rest with water & scraped it all off. About 350 sq ft. The concrete ceiling is flat with some straight lines (apart like in squares....slab?) & seems to have something still on it which washes off but I'm hoping I can leave it on. Like a bond filler or something? The ceiling seems devoid of moisture.

Anyways my question is this. What is the best way for me to re-apply stucco to this ceiling so it looks like it did before & do I have to wash away that stuff before doing so?

Thank you.

 

Welcome, Donny!

You probably need to prime the ceiling now that it's clean and then apply a product like this:

USG Acoustical Plaster Finish by USG Corporation

It's applied with a texture hopper / gun and you would need a big enough air compressor and hose that will deliver a sufficient amount of air (c.f.m) to blow the texture. Usually you dial the regulator on the air compressor down to around 30 lbs because more air isn't a good thing in this case.

The stuff makes a holy mess so you'd want to move furniture, cover the floor, then mask the perimeter of the walls at the ceiling with tape and then tape painters plastic onto that. You'll probably also want some goggles.

You only fill the hopper about half way full, be careful not to dump it on your head as you spray (not that I've ever done that... LOL) and have a helper around to help you reload. Keep a wet edge, and don't spray it on too thick at one time. IMO a light, even coat is best, not a heavy one. You'll probably have to play with the dial in front of the gun to get the right size orifice- start with the medium sized one. Let the first coat dry and then come back and spray another one that is perpendicular to the last.

You can probably find some good videos on youtube also. Search for acoustical texture or acoustical spray.

 

What is the stuff still on the ceiling after scraping off stucco? Should I leave this on & prime right onto it or should I wipe it off?

Is the roll method easier?

(2 more questions...sorry.)

There is one small gap in the ceiling and I can swear it is wood?!!! (Strands of something). Is that possible?

Finally while scraping off hall part I kinda broke ceiling drywall at entrance to kitchen. What do I put in those gaps before putting on stucco & how do you do a straight line of stucco with no wall meeting the ceiling? Put up a straight bit of plastic sheet?

btw.....thank you.

 

Hard to tell what's on there... i can't see it from here! LOL But I would assume it's either primer or maybe a base coat of spray on texture. In either case, if it's adhered well, and doesn't flake off or bubble up when you wet it, then you should be able to prime without any problem.

Rolling is okay, but if anything on the ceiling is loose, it will be in your roller. Airless sprayer would be easiest.

Can't answer your question about the strands. I wouldn't think it would be wood. I also can't picture what you mean about breaking the drywall. Do you have a drywall ceiling butting up to your cement ceiling, and they are both about the same level? If so, you would probably need to get a dry bag of Durabond Easy Sand 5 or 20 minute mud, mix a little bit up and prefill any holes until they are flush with the rest.... then you'd need to tape over those repaired areas with paper tape and finish them just like you would a butt joint. If your textured ceiling has to stop there, I'd probably try and screw a board to the ceiling there to serve as a "stop".

 

Thank you xsleeper!

The kitchen ceiling doesn't have holes. Just not straight anymore after scraping off popcorn near kitchen entrance. I did best I could but broke off a wee bit here (inch in) and there at kitchen entrance only. That drywall isn't straight anymore.

Can I prime that bit on kitchen drywall ceiling after applying filler to flush (mud & or duraband) then just simply put new stucco on that ceiling too a wee bit into kitchen? Know what I mean?

What I mean is, after doing the prep: Apply stucco to livingroom and hallway concrete ceiling & then just a wee bit in on top of fixed part of primed duraband fixed drywall ceiling at kitchen entrance? will the stucco stay on if I prime this too?

(I would put straight plastic at kitchen entrance except that 2 inches in of drywall kitchen ceiling that has been flushed & primed, then apply stucco onto that too.) It is almost level. Just a slight drop and I don't think it would be noticeable.)

This ok xsleeper?

Thank you & sorry for taking so long getting back. I am doing this this weekend for sure.
