Stucco Over Old Asbestos Siding.


Has anyone out there ever heard of applying a traditional stucco with metal lath over the old asbestos siding. The idea sounds good to me and I would like to offer it to a client of mine. Any comments ?

Plan on using 1.5 in. lath screws or even longer galvanized. Would want to get attachement into framing. May need to pre-drill.

I could lathe playdough sure, question is would it be a good idea? Masons messing with asbestos doesnt sound like something coming from the smart department.

Re: Stucco Over Old Asbestos Siding.


Have you ever driven any fastener into old asbestos siding? It will crack, shatter, and leave a bulge under the lath. Remove it and have peace of mind knowing you have a solid flat substrate behind with proper house warp and flashing.

I have installed siding over those without problem, One thing you remove it that is abatematewhich requires proper training and license to do. Home owner can remove (at least here) but I can't.

Re: Stucco Over Old Asbestos Siding.


Removing would be best, but it has been done and is still being done. I see no problem with it. If there is a bulge, just hammer it. You may want to wear the proper equipment when working with asbestos.

Won't that cause asbestos dust?

Wow, giving advice about asbestos isn't your main day job, is it?

That is throughly a lack luster response on your part

I believe banging nails into it and breaking it also releases dust.

IMHO removal, by pulling individual nails and shingles, is the only option.

Check with AHJ in your area, as Randy said, you may need abatement company.
Here it is also, only the HO, in fact, they can throw loose shingles right in the trash. Abatement company must double bag, tape and dispose of in an approved site.

Good luck,

I think you have to remove it...besides the fact that you wont be able to drive a nail into it properly and your stucco wont have proper life span,its dangerous for you,your workers and customer and uncessary liability that you will carry with it.

Re: Stucco Over Old Asbestos Siding.


the job i am currently on has asbestos shingles on part of the original house.We tried using an air stapler,but most of them bent and didnt attach to anything.We then tried using an 8 penny nailer.This to didnt work as the nail went thru the shingle and lath.We ended up using a screw gun and small washers to attach the lath.This works out great.
I personally am not afraid of what little asbestos dust would be freed by breaking these shingles.With all the old building around this country chocked full of asbestos,and you know its not all going to be contained,Im sure we breath in more than what would be produced here.Besides we as masons inhale pounds of brick dust,cement and other things everyday on the job.

Re: Stucco Over Old Asbestos Siding.


Any modification to Asbestos siding, if I recall, requires Abatement.

Anyone?

Anyone?

When Asbestos was first being deemed carcinegenic a study was done on the miners in Asbestos Quebec. There was a much higher rate of lung cancer than the statistical average. Anyone here ever been to a small town in Quebec and seen how many cigarette smokers there are. Everyone. Especially in the '60's and '70's.

When I was younger i worked with a carpenter and we did a lot of insurance restoration. I wasn't around when this happened but he was on a job at a school that had flood damage. In the course of the job asbestos was discovered and had to be removed. Everything was sealed off, and the workers went in with hepa filter masks and body suits. He said he could see that once the workers were behind the plastic barrier they all took their masks off and went to work.

I'm not saying that asbestos won't kill you cause I really don't know and of course you should follow whatever the law is but....

Re: Stucco Over Old Asbestos Siding.


My 2c is about how you can approach it. I advocate an inspection prior to moving forward. However, if you wish not to do so, there's two things to consider. Is it damaged or in tact. Apparently, asbestos can remain in tact when it's in a application state and providing itself useful.

Even if it's minimal, I believe you will be tampering with it and PPE(Personal Protection Equipment) is no joke here. Asbestos I read can be found in the ground as well for instance, the word itself means inextinguishable. IMO the kiln clay particles from a brick are a walk in the park vs. any asbestos fiber exposure.

I would play it safe. I read any exposure more than the size of your hand deems it a minor repair no longer. Unintended hazards for the HO, crew, or oneself seems a little delicate. Mind you, I have no training in asbestos- I'm just talkin'

Re: Stucco Over Old Asbestos Siding.


Yeah, Dom-mas when you mentioned the eskimos I went and looked up some asbestos stuff as well. When I was about 7 I lived outside Philly at my Grandfathers. He was renting then. In the basement I remember my parents kept a lot of their stuff, they were young and mooching. My dad made Rc, and motor boats with the little plane motors. I would go down there too. Anyhow it got condemned for asbestos and is back now. We lost our stuff, like a little jean jacket my G-pa gave me with his army pins after he retired.

OP might not need a full on abatement team and force the HO into an expensive removal. I am also against regulations and bureaucracy. I do think having an experienced asbestos guy/girl should definitely share their expertise with OP.

Avoid it like the plague dude.

Re: Stucco Over Old Asbestos Siding.


Some things can hang around and haunt you for years, some until your estate is settled. Why get into one? Find the proper authority in your state, ask in writing and get a response in writing. Don't work on this outside your clear legal authority. The HO, and neighbors are taking note.
