What are my ceilings made from?


I live in south florida and my house was built in 1971. I was attempting to remove the ceiling texture so i can put up knockdown and hard run into an issue. First off the texture kind of looks like popcorn but doesnt come off when scraped with hand and is very very hard. They are smaller crowns the most popcorn i have seen. So i went to where the AC vent is and started chipping away where the ceiling meets the vent and under the texture is a very hard, dense, material. Unlike drywall that i have used before. From the crawl space it looks like smaller sheets of drywall. The walls are the same thing. Very dense. I dont know if its some sort of plaster but ther is n lath. Here are a few pics of what i am talking about. Also any tips on removing the texture? I dont want to redrywall the ceilings and i have tried wetting and scraping. I can get the crowns off but cannot get down the the paper. Should i scape the crowns and sand the rest or a skim coat of joint compound? I am going to use knockdown so it doesnt have to be completely smooth.

Built in 1971? ....

First thing: I would suggest that you get it tested to see if it is, or is not,....asbestos based....before you do anything to it...

Besides that - It looks to be plaster, but get it checked....

Plaster without lath? From the attic it looks like drywall. Is there a type of plaster board?

Yes it is. My parent's house was built in 1968 with the same materials, the same way = plaster.
My home was built (1950)the same way...with these types of boards and plaster...

I just had a popcorn removal company come out and they said that it doesnt look like popcorn ceilings. He said that it kind of looks like perlite. There is an area in my kitchen where the drop ceiling was removed and popcorn was sprayed and the guy immediately said that was popcorn and the rest wasnt. There are some large chunks in the ceiling that he said may be some sort of popcorn that someone tried to add but he said it didnt look like it was popcorn. He also said that it was plaster ceilings and walls. The texture is hard, very hard. If its not popcorn do i still need to be concerned with asbestos?

Ive ripped out walls for years and never seen anything that looked like the stuff thats suppose to be drywall in your pics.

As far as advice on acoustic (popcorn) texture removal, if its a small area of removal I use a belt sander. If its a big area of removal like an entire room, I mix hot water in a garden sprayer and wet the heck out of the ceiling a few times. Let is soak and penetrate and then scrape it off. Its messy but that's the only way Ive done it that works. Not knowing what your supposed drywall really is, Id wet rather than belt sand. You dont want to breathe in asbestos dust or anything.

I would just go over it with new 3/8" sheetrock and 2" drywall screws. Tape, sand, paint. That way you are not disturbing it and the job will be done with 1/2 the effort of trying to scrape the cement-like plaster down.
IMHO- That ceiling is a 110% candidate for a 'go-over' with 3/8" sheetrock....

Try a local Wallboard supplier. Check your local telephone book or do a search online for your area....

The 3/8 cover sheetrock is the easy route, but Ive just never been in favor of hiding anything. To be honest!!!!!!!! if it were me and me alone, Id put on a 3m mask and safety glasses, where a long sleeve shirt and hat and rip the whole darn ceiling out in 30 minutes and resheetrock it. I know that scares a lot of people but Im 42 years old, in good health and Ive done it for years with not a spec of trouble.
I cant however recommend you to do that for yourself, as your safety is paramount. Ive been doing this for 22 years but maybe you should consult an expert. Dont trust me, Im just an old wise farm boy.

But... Why?

Why waste all that time, energy, create a huge mess, possibly release asbestos into the air, when all you have to do is go-over it?? We have; ripped down ceilings, re-textured them, re-sprayed them, scraped them down, re-coated, re-framed ceilings, re-sheetrocked, re-built ceilings...re-'everything-ed' ceilings....

As far as the 'going-over' method: We have literally done close to about 1000 ceilings (or more?)....like this .... over the past 22 years, and every last one of them is still up and looks great....

Infact, we just did a whole older apartment over (walls included)...just like this last week....There was even an area there, that we had done about 6 years ago this way and you could not even have guessed it was ever gone over...

I understand the thought of not wanting to go over something and 'hide' it....'IF'.... it's going to be a problem in the future, but, the only thing that would ever be a 'problem' or 'bring down' a "go-over" ceiling...... is an earthquake or a fire...

...FWIW - We do this stuff for a living....

the trouble is that its all easy for you, but the next guy to come in and say fix a water damage problem is left with a mess. wet sheetrock, slimey old texture, asbestos, a second layer of who knows what and whos knows what else.

90% of the work I do is fixing an old can of worms I dont care for cause some guy short handed the job five years earlier. Do you have any morals? Think beyond the moment! if everyone did thorough work then it would eventually make everyones job easier.
WOW AM I DREAMING...WAKE ME UP!

There are somethings that should be ripped down or require rip down, and some things that just don't. Your analogy of a burst pipe is ridiculous. A burst pipe is going to damage anything that is near it, 1 layer or 2 layers, so what?....We should know, we have done hundreds of water damage repairs because of burst pipes. (in fact -Doing one next week on 3 apartments - frozen sprinkler pipes....)

Anyways....
Going-over sheetrock is not short-handing, nor is it short changing. It is simply adding another layer of gypsum to fix it. Instead of scraping it down and skim-coating a 3/8" soft gypsum coat, which is common practice (AND WHICH YOU YOURSELF EVEN ADVISED ON THE SAME POST), it is adding a SOLID 3/8" gypsum layer (with the sheetrock). Obviously, which is better?

How many people add 2-3 more coats of paint over a bad paint job...They don't rip the drywall down to do it.....
Simply - "Ripping things down" to the studs - may 'feel' right to you, but is not necessary all the time, and with every issue.

We have never taken a course of repair simply because we 'feel' like we need to. Every course of repair or replacement or build is well planned and well thought out - for specific reasons, based on each job.
We are not a DIYer company, we are 3rd generation builders (We build entire custom/spec houses, additions and remodeling) in addition to being authorized to do commercial/industrial/residential work as well as; moisture/water/insurance repairs. We have an unrestricted class A construction supervisor's and builder's license. We work on a regular basis with architects, engineers, designers, and building inspectors. We certainly do know what we are doing and NEVER have, and never will short hand/change anyone, neither will we avoid doing a 'thorough' job... Our work REVOLVES around fore-thought and long term results. We don't think for 'the moment' - we never do -as you implied.

Our Morals:
22 years in the business with not a single complaint. Not a single call back.......We do not advertise ... ever. We are booked completely through 2007 simply by word of mouth....That says alot about our morals, how we work, our level & quality of work and .... how we treat people...

- Have a good day -

sflamedic From looking at your pictures and reading your description what you have is plaster over sheet rock lath. I know it was used in the 50's and 60's here. The brown or dark color is the scratch coat with a thin finish coat. If it is in good condition other than the texture I'd proceed as you plan.
