popcorn ceiling
 
can you put 3/8th inch sheetrock over popcorn ceiling?

On a ceiling?
I've never even seen 3/8 sheetrock.
Why not just scrape off the old sheetrock and finish the ceiling?
All the old popcorn would have to be scraped off anyway before anything went up.

I was talking to a fellow that did this and all his seams are now cracking. Everything must now come down to the bare joists.

What's the joist spacing?

i know in my area of the world after plaster board they were using 3/8". i go into lots of homes with it and stores here stock 3/8" for doing patches and what not. i wuldnt recommend 3/8" for the ceiling. i'd go to 1/2" ultra light or 1/2" sag res. or you can wet down and scrape off the popcorn and skim coat it.

It can be done if that's the only option.
I prefer to scrape it. http://www.youtube.com/watch?v=bH04m...layer_embedded

Sometimes it's better encapsulate it. Depending on what year the popcorn texture was installed?

No, not 3/8" if you are applying a water-based texture- per code; http://publicecodes.cyberregs.com/ic...002_par010.htm

As per manufacturers, Table 2,"b"; http://www.lafargenorthamerica.com/G...%20English.pdf

Unless the ceiling is cracking badly or otherwise failing, just bite the bullet and scrape the popcorn off. If it is like the majority of such stuff it was a mix of the crappiest ceiling paint, adhesive/binder and pellets sprayed on a non-primed surface. Wet it with a tank sprayer and use a nice wide drywall knife and it should come off. You will then be done with the hideous stuff.

Lay down disposable tarps because it is a mess. I will not lie. It is not a fun job but some of us have done it too many times!

Just know that depending on it's age, the stuff may contain asbestos.

It's not a hard job but it's a dirty job to remove popcorn. Everyone thinks to just add another layer of drywall is the easiest way, it hardly ever is. But why not use 1/4" sheetrock if that's the way you want to go. You don't say the dimensions of the room so I hope you can use full sheets so you don't have any butts, with ceiling lighting they are hard to make go away. You didn't mention crown if it's up you need to take it down, if it's not up you should consider putting it up. Then you won't have to mud and tape where the wall and ceiling meet.
