    Evening NES. I'm in the process of selling my home and I ran into a snag with my basement so here I am for some possible advice. I had some tiles that were tested for asbestos that ended up showing a level of 3% so I went ahead and had them removed. After the pro's came in to remove the tiles I had the basement re-tested which came back negative. Issue I have now is that the tiles left behind an aged black glue that looks like shit and after an hour of scraping yielded dismal results. As of right now I've got two dehumidifiers down there running 24 hours to see if they will help dry up the glue so it could be easier to scrape up.
    With that said, can anyone here give me a few pointers as what to use to get this shit off my basement floor? I'm looking to throw my house on the market next weekend so anything quicker/cheaper would be ideal

    Here are some pics of the floor.

    Epoxy paint? I did the last house just for the looks and the sealing properties.

    Heatgun to loosen, torch to burn (wear respirator - not a dust mask)

    Epoxy paint is awesome - again respirator and good ventilation or you whole house will smell like epoxy.

    Stop scraping that mastic immediately and have it tested by a different company The tiles spawl into the adhesive and most asbestos exposure in construction besides pipe insulation and joint compound is from hot mastics. Black mastics are almost always hot.

    Nothing is going to cover over or stick to that adhesive. The stuff doesn't play well with coats or adhesives over it. You will need to put carpet on a floating pad, thin plywood with new flooring over it, or a floating vinyl/engineered wood system over it.

    Alternatively use Dumond Chemical's "Peel Away" paste products to dissolve the adhesive into the paste (keeps the dust and anything toxic contained in a liquid suspension and scrape it up into a sealed bucket for disposal.

    It’s a basement dude. It’s not a brand new house. Let it go, shit like that is expected in a house of that age. Let the buyer deal with it if it bothers them, which it won’t

    Issue with this section of basement is that it is only half the actual size. The other side has oil tank, burner, laundry utilities and basement which doesn't look like this.
    I ran the moisture test and my basement sweats too much to have any type of paint stick
    Heatgun makes sense but would you simply torch it off or scrape afterwards?
    I had a feeling this could be the case. I brought it up to the company that removed the tiles, their response was re-sending me their post job test results. That Peel Away product sounds interesting I'll start reading up on it.

    This is another thought going through my head. The house was built in 52 so it's part of the flavor [smile]

    Did they test the glue? I'm assuming yes bc you said they came back.
    Some of those adhesives had asbestos too.

    Yes. They tested before and after to verify all traces of asbestos were gone, but honestly I have no idea.

    Torching it would burn it to ash - think an oven clean cycle. The smoke and stink may be an issue if you can get some good venting.

    I like the "it's an old house" idea best.

    Well, you could always pour a new concrete floor over it.

    Seriously, some carpet, incense, and glass beads hanging from the ceiling makes a great party place.

    Throw A new vinyl floor on top of it. Remove remaining studs and plates, drylok the walls. Clean basement sell houses believe it or not.

    Pour a thin coating of leveling cement over it and move on

    My Fathers basement has the same problem. I'm going to try and grind it off using a 1/2" angle drill with a 7" diamond turbo cup wheel, they sell them at Harbor Freight for $50. If the wheel gets gummed up, I will try what GM-GUY suggested and try burning it of with a big ass propane torch, the type that you burn weeds with.
    Good Luck

    Don’t create any dust ,grinding ect.
    Cover or leave it.

    The floating vinyl planks are pretty cheap and easy.

    $2 a ft.

    I’m for the thin industrial carpet toss a vapor barrier down before hand like 5 mil plastic. Glue everything down except maybe a clean corner so you can show them itnhas a barrier and glued down. One of the prior post pointed out an important point and that is the glue sometimes has trace amounts of asbestos. So not good for scraping or breathing in.

    that is a good idea about testing the mastic (black glue). If you do not have a place, Proscience Analytical in Woburn can do it overnight. Often the mastic also has asbestos, but not always.

    But check the initial inspection report....they might have already tested the mastic on the back of the tile sample submitted.

    I was thinking that it MIGHT only be stained black on the surface, and one of those concrete resurfacing machines might grind down the top layer to reveal a nice shiny new concrete layer. You can rent a machine, or hire someone to do it.

    use a hepa vacuum to clean up after, and use a respirator when using...just in case.

    Also...if it is not a moldy black substance, just re-tile right over it.

    it is worth a try....sherwin williams usually have a gallon or two of the stuff. but a whole floor....probably will need at least 5 gallons ($175). Try a single gallon first to see if it does the job

    My mother had the exact same issue in her basement when she prepped to sell. She just painted over the mess you have there.

    Interesting! They DO have two part epoxy paints for garage floor at home despot. Should hold up fine. Just use VENTILATION until it cures!

    Ask your agent about impact on selling price with the options you might consider

    my guess: sounds like he did not have a choice, was selling house, and buyer's home inspector demanded a test. After that...."leave it in place" is not an option...and the real estate person would have to reveal presence of asbestos in basement to any new potential buyers. Best to just be able to say "No Asbestos" at that point, even if it did cost him $2k

    For future reference, if you see a 9 x9” tile, those are often asbestos
