Does Old Linoleum Contain Asbestos? (Solved)

If you’ve got old linoleum flooring in your home, it’s normal to wonder if it’s hiding asbestos.

A lot of homes built before the ’80s still have original flooring tucked under carpets, furniture, or newer layers. And while it might just be outdated and ugly, there’s also a chance it contains something more dangerous.

In this post, we’ll explain if old linoleum contains asbestos, what to look for, why it matters, and what to do if you think you’ve got asbestos underfoot.

Does Old Linoleum Contain Asbestos?

Here’s the short answer: it depends.

Real linoleum (the kind made from natural stuff like linseed oil, cork dust, and wood flour) usually doesn’t contain asbestos.

That said, a lot of people call all old sheet flooring “linoleum,” even when it’s not.

Vinyl flooring, which looks super similar to linoleum, did contain asbestos if it was installed several decades ago.

Back in the day (we’re talking pre-1980s), asbestos was used in all kinds of building materials because it was durable, cheap, and fire-resistant. Flooring manufacturers added it to vinyl tile backing, sheet flooring, and even the glue that held it all down.

So while actual linoleum is generally asbestos-free, it’s really easy to mistake vinyl for linoleum when it’s been sitting in place since before disco was cool.

Signs Your Linoleum Flooring Might Contain Asbestos

There’s no foolproof way to tell just by looking at your floor, but there are a few clues that can raise a red flag. If you’ve got old linoleum flooring and you notice one or more of these, it’s worth taking the extra step to get it tested.

Here’s what to look for:

#1 Installed Before 1985

This is the big one. Asbestos was widely used in flooring materials up until the early-to-mid 1980s.

If your home (or the flooring itself) dates back to that era, there’s a decent shot it could contain asbestos somewhere in the mix.

It could be in the tile backing, the sheet material, or even the glue underneath.

If you’re not sure when it was installed, checking old renovation records or permits (if you’ve got them) can help. Or just play it safe and treat anything from that timeframe with caution.

#2 9×9 Or 12×12 Tiles

These sizes were super common in older homes, especially the 9×9-inch tiles. They were cheap, easy to install, and used pretty much everywhere from kitchens to basements.

Unfortunately, 9×9 tiles in particular have a strong history of containing asbestos.

Even 12×12 tiles can be risky if they came from certain manufacturers.

So if your floor is rocking these dimensions and it’s been there since before the ‘80s, you’ve got one more reason to pause before pulling them up.

#3 Brittle, Yellowed Backing On Sheet Flooring

If you’ve got old sheet flooring (the kind that rolls out in one big piece), take a peek at the backing if it’s already peeling or cracked.

Asbestos was often added to the backing layer to give it strength and stability.

Over time, this backing can turn yellowish and become dry or brittle. That crumbly texture is exactly what you don’t want to breathe in.

If you see that kind of material underneath the sheet, don’t touch it any further.

#4 Black Adhesive Underneath

Do you see a tar-like glue under your linoleum flooring?

It’s called “cutback adhesive,” and it was commonly used back in the day. It’s thick, sticky, and usually black or dark brown. TAnd this stuff very often contained asbestos.

It’s one of the more overlooked asbestos risks because people focus so much on the tile or sheet itself. But the adhesive is just as risky, especially if it starts chipping, flaking, or turning to dust.

If you’ve got black glue under your old flooring, that’s a solid sign to stop and get it tested.

Dangers Of Disturbing Asbestos

Asbestos isn’t dangerous just sitting there, buried under your furniture and rugs. The trouble starts when it’s disturbed.

Cutting, sanding, scraping, or tearing up flooring that contains asbestos can release microscopic fibers into the air. And you really don’t want to breathe that in.

These fibers are tiny, sharp, and they can stick around in your lungs for years. Long-term exposure has been linked to some pretty serious illnesses, like mesothelioma and asbestosis.

It’s not something that shows up right away, either. The damage can take decades to become noticeable.

That’s why it’s so important to avoid disturbing old linoleum flooring that might contain asbestos during renovation projects. Even sweeping or vacuuming debris can stir up fibers and send them floating into the air.

And once they’re in, there’s no way to get them out.

What To Do If You Suspect Asbestos

If you’ve looked at your linoleum flooring and a few red flags are popping up, don’t jump straight into demo mode.

Asbestos is only dangerous when it’s disturbed, so the safest move is to pause and take the right steps before touching anything.

Here’s what you should do next:

1. Stop any removal or renovation work immediately
2. Keep the area closed off and don’t let kids or pets near it
3. Avoid sweeping, vacuuming, or touching the floor
4. Contact a certified asbestos inspector to test the material
5. If asbestos is found, hire a licensed abatement contractor for removal
6. If removal isn’t needed, you may be able to safely cover it with new flooring
7. Never try to remove asbestos flooring or adhesive on your own

Bottom Line

So, does old linoleum contain asbestos? Maybe – but probably not if it’s true linoleum. The real concern is with vinyl flooring, which a lot of people mistake for linoleum.

And if it was installed before the mid-1980s, there’s a decent chance it could contain asbestos in the backing or adhesive.

Taking a little time to test it can save you from way bigger problems down the road.

Plus, it’s way less stressful when you know what you’re dealing with.

FAQs

Accidentally Removed Asbestos Linoleum

If you’ve already pulled up some flooring and only found out after the fact that it might contain asbestos, stop working immediately, seal off the area if possible.

Call an asbestos professional, and let them assess the situation and test the air if needed.

If it was a small area and you didn’t break or sand anything, the risk may be low, but don’t guess. Let a pro guide you from here.

When Did They Stop Using Asbestos In Linoleum?

Asbestos wasn’t used in true linoleum, but many people confuse linoleum with vinyl flooring.

Vinyl sheet flooring and adhesive materials that contained asbestos were used until the mid-1980s. By 1986, asbestos was mostly phased out of residential flooring products in the U.S.
