Guess I will find out from te abatement company this week anyway. My floor is a little over 100 sq feet so don’t think removal will be that expensive. Homes built in the 20th century commonly used black mastic as their ceramic tiles adhesive. They also used other flooring materials like linoleum, among others.

You can get rid of it safely using otherwise. This adhesive tends to be gummy and too thick, which makes it hard to remove manually. We will find out the simplest method of asbestos encapsulation and how to get rid of it. Meanwhile, let’s have a look at how you can differentiate asbestos and black mastic. I’m not familiar with loose lay rubber back carpet tiles. The issue in removing adhesive are a smooth floor so they lay flat AND compatibility of the backing with any residue.

Carpet Tiles

The rising tide of lawsuits over asbestos-related diseases, however, finally compelled most manufacturers to stop adding asbestos to adhesive products. In 1906, the Philip Carey Manufacturing Company began selling an asbestos-based fibrous adhesive for more general construction use. 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. Check with the manufacturer about using chemical solvents.

What I would heavily suggest is to acclimate any product you get for at least a week to make sure that the product’s moisture content is within 2% of the subfloor’s moisture content. I forgot to add a couple of things to my questions below. I have heavy exercise equipment and a desk that can’t be removed from the basement, during installation, without having to disassemble them. I know certain floors require that nothing can go on it right away. I was hoping for flooring that will not only hold the weight, but that it can be put on the floor right away.

To test this, soak a small area and scrape with a putty knife or wider blade such as a small drywall knife. If it’s water soluble, even the hardest mastic softens. A low-temp, infrared heat gun and scraping might work if water doesn’t. If both of those methods fail, consider a solvent such as paint thinner.

Super CMR Citrosolve Citrus Mastic Remover is formulated with the high strength of citrus for removing black mastics commonly found under 9” and 12” vinyl floor tile. I am in the process of getting my mom’s house ready for sale. On the concrete rec room it was very easy as the tiles were coming off on their own anyways. It was like flipping pancakes and took about 30 minutes for about 400 ft2. On the stairs it was a lot better adhered and I used a water sprayer and iron.

Can I Install New Flooring Over Black Mastic?

There are now new trigger words affecting our industry in the last month or two. Several years ago there was another issues our industry that needed addressed and dealt with, and they did. Every installation instruction from manufactures dealing with any type of glue down or any adhesive states to not scrape, grind black cut back adhesive.

  • We want to know if there’s a hardwood layer since the rest of the house is original.
  • Photo 10 – The floor tile in this picture may have been removed non-friably.
  • The first three of these diseases are terminal.
  • Some tar-based adhesives will dissolve or soften in the presence of soap.
  • By the time you apply a new glue and floor, any fibers are most likely going to be “permanently” bonded in there and unable to get out.
  • They told me if it was old vinyl or linoleum ot had to be tested or they couldnt do a thing to my floor.
  • Tile needs a smooth, level surface to be installed on.
  • Stapling carpet over the new treds is a simple venture.
  • Continue removing the strips until you’ve removed the entire linoleum surface.

As you said, your uncle actually worked with asbestos, so I would assume he was exposed to it for several years on a continual basis. I really think this little bit of tile removal won’t post a serious risk. But I do need to know how to safely discard the tiles, and how to safely remove the adhesive so that it doesn’t stir up more asbestos-filled dust in the air.

Was Asbestos Previously In My Home?

Look at your property deed, title, or tax appraisal to find the year your house was built. Keep in mind, unless your tiles are cracked and the adhesive is exposed, any asbestos in your flooring is not actively dangerous. Asbestos adhesive removal is best left to qualified asbestos abatement professionals, especially when old asbestos glue daubs have become friable . Buying or remodeling an older property can be exciting. However, one item that can be uncovered is vinyl floor tile installed before the late 1970s.

Scraping or sanding it manually can release the minuscule fibres into the air that can enter one’s respiratory tract and sow the seeds of chronic diseases. As I stated earlier; ASPHALT 9×9 tiles from the 30’s to 1958 were the norm and installed with “cutback” black mastic. Black mastic was also the norm for all Bruce hardwood floors. There is a very limited number of materials that can be applied over top off asbestos based cutback adhesive.

Can You Seal Or Paint Black Mastic?

You need to “Encapsulate” (spelling?) them… DO NOT take them up. Place concrete board down and tile over top of it… worked for us. If some asbestos was “disturbed” when your house was remodeled before, the air is no more contaminated than it would have been from having the flooring installed in the first place.

You can also paint over the asbestos with a thick oil-based paint to seal the fibers into the floor. There are DIY kits that supposedly allow you to determine whether or not a material is made of asbestos on the spot. These kits don’t tend to be very accurate though, and they often can’t test mastic adhesive anyway. This will not be true of mastic that has been exposed to the open air for some time though, since the mastic will dry out and lose a little bit of the shine. Double dump valve with gate – Motor driven, double gate valve for continuous removal of collected dust.

I might post and ask about it and gather opinions. At the moment I’m just being careful to limit my exposure. I’m not sure how to deal with my stuff and with the legal/formal aspect. No, Asbestos doesn’t stay lingering in the air for “many years”.

Asbestos vinyl tiles are considered to be BONDED materials. That is, the asbestos fibres are bound into a matrix material that is vinyl. The asbestos fibres are not homogenous throughout the vinyl tile matrix, rather there can be clumps of asbestos fibres in some places and none in others within each tile. If you removed so few tiles, I can’t imagine that you would have anything to worry about. Generally, people who have issues with asbestos exposure are people who have worked with it every day as part of their job. Such limited exposure from a few broken tiles doesn’t seem like enough to worry about.

If you are installing carpet and using good quality pad there is no reason to remove that old mastic. Vinyl over the mastic is a trickier situation as it would be tough to get the floor as smooth as necessary to prevent early degradation of the new floor. if you try and tile over old adhesive it can be a bit more tricky but it can be done. all u need to do is to score the surface to give the adhesive something to stick to but make sure that any flaking paint is removed and then PVA.

Can’t wait to see the transformation of your house into a home. It might be best to have that tested before sanding. flooring over black mastic However if you “wet sand” it, there would be no dust. 😉 Just keep it damp so nothing becomes airborne.
