Topic tags/keywords: asbestos floor sealing rez-seal

I’ve been asked to help renovate an old (1940’s) building to use for a youth center. The part they want to use as a stage has about three layers of tile flooring, and I’m sure that at least one layer is made of asbestos tile. Removing the tile is out of the question, so the owner has asked if I know of a product she can use to seal in all of the bad stuff (like asbestos).

The final floor doesn’t need to be perfectly flat, or even close to it. We’ll be covering it w/ pallets, w/ a final layer of smooth plywood. She has about 5 gal. of “EUCO Rez-Seal.” I checked out the Material Safety Data Sheet (MSDS), and it looks like this stuff is meant for outdoor use only; it gives off all kinds of harmful organic fumes as it cures. And even if this stuff is OK, 5 gal. won’t be enough.

So, what do you recommend as a sealant for this type of floor?

Epoxy floor coating would work, might need to be etched but if it looks bad after etching it doesn’t sound like it would be a problem.

You need to get hold of OSHA and see what they recommend, there is a specific product for this. Liability-wise, this isn’t something to short-cut on.

Comin from an asbestos and demo contractor its perfectly legal and an accepted practice to cover existing asbestos flooring material with another flooring material. It would be considered encapsulation. Theres no special product that needs to be put down other than the new flooring that we have ever been required to use here in CT.

Vinyl asbestos floor tile is usually regarded as non-friable meaning disturbing it wont create any dust. In some states non-friable material can be removed without a containment and negative pressure but one should be certified in the removal of asbestos and use the proper PPE.

If youve got any other questions that i can help you out with in regard to asbestos feel free to send me a PM jim or id be happy to answer them here as well.

A few years ago someone asked me to help him remove the insulation from their boiler pipes in the basement that had asbestos in it. I asked why and he said because he didn’t want his baby being exposed to it. I said ‘is the baby coming into the basement?’ and of course the answer was no and the insulation which was perfectly incapsulated could have stayed and continued to do it’s job.

I don’t know why it needs to be sealed. Asbestos is only dangerous to people who worked with it or the people who remove it. Just through a new floor over it and you’ll be good. Tape down 4 mil plastic if it worries people.
