I specifically asked him about where we might expect to find asbestos. He said plumbing insulation perhaps., while standing on the asbestos sticky-tiled floor. I wouldn’t have been able to leave the tile alone once I figured out I could pop them up so easily. I’m glad you posted this because I didn’t know there was asbestos in floor tiles.

The floor then ultimately would absorb the penetrating encapsulant, theoretically sealing in the asbestos. Whenever we find black mastic on a floor,, we coat it with a material called perfectprimer It sticks tot the mastic, and then bonds to any tile, glue or epoxy customer wants to apply. The odors you describe regards to the black mastic are common, especially when in an “always damp” situation, especially after having been recently disturbed by your removal of the tiles. Thinking it is also likely that at some point you either created friction during removal, and/or used the assistance of heat to help in your removal. BTW, this suggests that a slury of mineral spirits will be your likely most sucessful aid in its removal.

Huge difference in smell for the while home it made. I have an attic that had the tiles as well on the plywood where there is tons of black mastic. It smells like tar or some kind of old odor especially when it heats up in the summer. I know they sell mastic removers; which I’m using in my basement to seal the floor afterward. I’m thinking of just ripping the plywood out and putting new down since it creaks when you walk on it because they used nails. So, removing old linoleum or vinyl flooring may come as a surprise to some homeowners when they see smears of some type of black adhesive between the tiles and the subfloor.

Once again, read the instructions and the safety measures on the product label several times before starting.

Calculating Asbestos Removal Costs

Apply some water to a small section of the adhesive. If the adhesive used was organic mastic, the water will begin to soften it, allowing you to scrape it off. In the 1990s, for example, two engineers filed lawsuits against North American Refractories Company, claiming they developed mesothelioma using the company’s gunning mix.

Then, scrape away the mastic with a chisel or an edge scraper. Alternatively, if you’d rather use a heat gun, be sure to wear heat resistant gloves as mastic is flammable. Joining the team in February 2008 as a writer and editor, Michelle Whitmer has translated medical jargon into patient-friendly information at Asbestos.com for more than 12 years. She was quoted by The New York Times on the risks of asbestos exposure. Some asbestos adhesives can be removed using chemical solvents, but these chemicals are not compatible with all types of adhesives and they can damage or stain the subfloor.

Most of the cutback I’ve dealt with is not very hard and I doubt that any skim will hold up well over time if it isn’t removed. It can be tiled over, which will encapsulate it and prevent the particles from becoming airborne. However, this is a matter of local building codes, so check with your local health department or building inspector before doing so.

But I do think once it’s done, I’ll still order an air quality test just to be on the safe side. 🙂 If it were just me living there, I’d probably not really worry about it.

Keeps the tile from drawing the water out of the mortar.

There should be some kind of warranty for the labor. Rotary lock with hopper, rotary valve and drive – Motor driven multiple blade rotary valve provide air lock while continuously dumping collected material. Can be used with hoppers under either positive or negative pressure. Flanged for connection to dust disposal chute. Side view with supplied air island, door for drossing lead pot, access for burner maintenance, kettle, work opening and Dynacast. I also agree that much of the general public’s fear of asbestos is overblown.

Permitting and licensing will vary from state to state, but all waste removal must meet minimum EPA Laws and Regulations for safe disposal. Dormant asbestos doesn’t pose a significant health risk and typically is contained rather than removed. Encapsulation costs much less than removal at $2 to $6 per square foot to enclose and seal off asbestos. The asbestos fibers may settle in the lining of internal organs and cause irritation. Over time, irritation may lead to conditions such as asbestosis, pleural thickening or pleural plaques.
