Good to hear. And happy you went for the proper removal option.

Despite some advice upthread that’s it ‘not that bad’. You do not want to mess around with Asbestos.

Apart from anything else, the problem is there is no ‘safe’ exposure level. People can trot out all the examples you want of asbestos miners with no issues. But equally there are any number of cases of people developing Mesothelioma from very minimal exposure to it.

The lab I work in is in a plant that contains major amounts of asbestos, so every employee is certified asbestos supervisor. So I have a little experience in the material.

Do not remove yourself. The type of removal you will need to do is called “gross removal”. It’s the worst method for fiber release. It will be almost impossible to properly wet down the material. To properly contain the room two layers of plastic poly for walls and floors will have to be set up. The room will have to be under negative pressure with a HEPA filter to contain the fibers, and a shower with filtered water. Clean up will have to be with an actual HEPA vacuum (not same thing you buy at Sears), and the plastic wiped down with a surfactant. Clearances air samples will also have to be done to say the air meets EPA standards.

I would suggest taking a bulk sample to a lab and getting analysed. It would cost around $30.

I would also suggest in the event of a positive result getting a professional to complete abatement. You will not be able to complete this project without endangering yourself or family.

If you PM the specific details of the project, I can ask the guys in our EHS unit for a ballpark figure on cost for you to hire someone.

Here is the link to a lab that has locations in California

Again if you had just floor tile or mastic I’d say do it yourself, but not this stuff.

No problem RetroVertigo, you never know who will be reading this thread in the future. Additional information is always welcome.

Since he’s going to be making a mess regardless the room needs to be blocked off. Before he’s done make sure he’s vacuumed all the dust. Wet mop when he’s done and call it good.

Not legal in California. We don’t advise on not legal things at the SDMB. The legal route is to hire someone certified to remove it, figure $3k and up.

That’s what I was thinking, too - this is not like picking up and disposing of hard floor tiles. Scraping a popcorn ceiling off will get that shit _everywhere_.

Glad to hear you got competent guys to do the work, **Arnold.** 🙂
