Nicholas,
I have been asking arround and spoke to a veteran floor guy last night. It looks like the odor (which I have also but not the mold) is comming from the moisture wicking up through the concrete slab (hydrostatic pressure) and reactivating the cutback(old black adhesive) under the tiles. The odor should be worse in the humid-wet weather. It had been recommended to use Dry-lok ( a kind of latex concrete paint used for basement walls and such) over the tiles which should seal it. Then padding and carpet. My thoughts are to maybe put down sheet vinyl over the old tiles to seal off the floor and then padding and carpet? Just wanted to let you know.

tile over it. It's not worth paying the men in the white suits to take out the asbestos. As long as it's not disturbed, you're fine.

That is the most logical / best explanation I have heard yet. I always suspected something was gassing. Moisture wicking up and reactivating the cutback would definitely do it. Now to just figure out what to do about it. Even if we re-tile or threw down hard wood over the black tile we're still going to have this chemical odor problem. It seems like the only real option is to have the old tile removed, break up about half an inch of the old concrete, pour fresh concrete to level it out, seal it then tile / hardwood over top..

Nicholas,
I just figured something out. My basement had a very strong musty smell when we moved in two years ago. I put a dehumidifier down there and no more must smell. I even have a grand piano down there now. My neighbor with the same basement with the same tiles as mine was having moisture issues with his carpet which was over the tiles. A dehumidifier did the trick for his basement and no more moist carpet. I suspect your odor increases in the wet, humid weather. and decreases in the winter (dryer) months. I think its more about the condensation and in your case (from your pictures) maybe you have enough moisture build up to cause the mold and mildew (which might explain the sickness part ). Let me know if you decide to try a dehumidifier. Thanks.
Paul

Tile over asbestos tile?


Hi all. I'm new to this thread but have the same problem. I have asphalt tiles that I have had tested and they contain 10% asbestos. I want to put down both tile flooring and floating cork flooring. So although I would rather leave the asbestos tiles undisturbed, for some reason, the previous homeowners ripped up half the asbestos tiles and replace them with newer, squishy vinyl tiles. And when I say half, I mean like half of each room. Don't ask me why. It is sort of random. Therefore, my only option is to remove all the tiles, vinyl and asbestos. I've read Gone_Fishing's adventures and his task list seems like a good starting point. I've modified it slightly since I live in Hawaii and don't have a heater.

1) Seal off rest of house
2) Soak tiles in a soap/water mixture
3) Wear some tyvek, gloves, respirator, and goggles (I'm not sure what tyvek is)
4) Use putty knife to remove tiles
5) Put into plastic bags and dispose of correctly.

My questions are:
a) What is the soap and water mixture in Step 2?
b) How would I remove the mastic? I have to remove the mastic since I am putting down floating floors in some areas so there would be no thinset to cover the mastic. I'm assuming the mastic also has asbestos (I didn't have this tested). I saw one post recommending Feather Finish. Can I use that over the mastic if I'm putting floating floors over it?
c) How long do I have to let the floor dry after removing the mastic before I can tile?

Thanks for your help

Also, one person mentioned "...you should not sweep the debris causing airborne dust. You should not vacuum the dust without the proper 3-stage filter. It is best to mop the areas using the proper chemicals." Does anyone know what chemicals he is referring to?

Tile over asbestos tile?


My young daughter and I have lived in a 1950s rental home for two years now. For quite some time, I have been concerned about the home we're in... ...both bedrooms have popcorn ceilings (which apparently are flaking, as each night there are "crumbs" on our beds) ...the living room, kitchen and hallway ceilings have what may be asbestos tiles ...the living room, kitchen and hallway floors have dark, almost black, vinyl/asphalt tiles (identical to the ones pictured in this thread) and the floor tiles are broken/chipped all along the walls and in the door thresholds (I believe that's what they're called) going into each bedroom ...the house is made of concrete, with the exception of one interior wall separating one bedroom from the living room and two interior walls separating the bathroom from the adjacent bedrooms ...the house has a musty smell ...the bedroom closet containing the bathtub access panel reeks--any clothing, shoes and the like left in there for only a few weeks smell musty; also, there is a 2'x4' area on one of the closet walls in this closet that appears to be moldy ...the bathroom window--covered in black and white tiles--always has black mold growing on it (the mold is also in between two window panes) ...the bathroom toilet "sweats" continually ...the kitchen cabinets--most of them--have a gray-colored mold growing on the inner concrete wall near the ceiling (the cabinets were attached directly to the concrete wall) ...the original 1950s hot water heater was finally replaced only two weeks ago ...the water pipes running under the house (from the kitchen to the bathroom) are corroded (the plumber who replaced the hot water heater said that the reason my washing machine "drain water" was backing up into the drain pipe and flooding my kitchen was due to a pipe underneath the home that had broken; he said he used a snake to unclog all of the mud--or something like that--that had gotten into the pipe, which was why I hadn't had hot water in my home for two weeks; needless to say, I have a "slum landlord") I may be forgetting other items of importance, but with what I have provided here, could this house be contributing to the overall ill feelings that my daughter and I have? In September, we were in Louisiana for three weeks, and while there, we felt perfectly fine. In fact, whenever we leave our home for more than a few hours, we begin feeling great. Oh! And we also have trouble breathing when we are inside our home.) Should I have all the suspected asbestos/lead problems inspected? My guess is, yes. I cannot afford to pay for inspections myself, and my landlord is "slum" so it is of no use to even ask him. (He would only do so unless court-ordered or threatened with a suit.) Thanks for any help!

Tile over asbestos tile?


First - This might have been better off as a new post.

First with your residence - begin looking for a new place. Don't do anything that would cause you to loose money, loose a security deposit or anything. Just move when you can. Look around. You may find a better place for less money.

Second - Inform your slumlord of the issue. Put them in a letter and keep a copy for your self. Even if he does nothing at least he is on notice.

Third - CLEAN - Bleach and water. Scrub everything. That will kill the mold. Keep windows open whenever possible. Use a bathroom vent fan, if you have one. Use AC if you have it and can afford it (not with windows open).

Lastly - The popcorn ceiling could be painted. This will keep the crumbs off the bed and encapsulate any possible asbestos.

Good luck in finding a new place, now get moving.

Tile over asbestos tile?


I had carpet over asbetos tiles over concrete. I want to lay ceramic floor tiles. I've removed the asbestos tiles & 90% of the mastic. Unfortunately the cement floor has chipped from the nails holding the carpet strips down. What to do? Remove all Mastic? How do I fill or fix chips. I doubt I'll be able to get all the mastic up 100%. How will this affect my next step & what should it be? P.S. Orange King works much better than the bean goo. I'm getting mighty discouraged.

Tile over asbestos tile?


This is an old thread, but there's some dangerous misinformation.

The technical data for Ultraflex 2 says "Do not use over...substrates containing asbestos." It's in the Limitations section on the first page. My guess it that it's safe to put it on but if the covering tile is ever removed then the asbestos tile under it may fall apart and release asbestos.

I've read about temporary/permanent construction adhesive and it had the same warning. I'm interested in this because I want to install a steel track on a floor that currently has asbestos tile and I'm trying to avoid drilling. I'll probably lay "grey step stone" where under where I want the track (only one sq. ft.) and hold it down with an L bracket attached to the wall then screw the track into the stone. Or I can glue the stone to the wood on the bottom of the wall that the baseboard gets nailed into. It wouldn't work in most cases but it should work for me.

One asbestos fiber in your lungs can cause disease a decade or two down the road. It's not worth the few hundred bucks you'll save DIYing it not to see your grandkids, etc. If you insist on doing it, research best practices to protect yourself and your family. Have your flooring tested, also. It can be as little as 25 dollars for the test.
