While modern linoleum flooring does not have asbestos, older lineoleum flooring may.

Asbestos is a hazardous material that is present in some older linoleum flooring materials. It can cause lung cancer, mesothelioma, cancer of the larynx and ovaries and a health condition called asbestosis caused by fibrosis of the lungs. People with asbestosis can have debilitating breathing problems and a chronic cough, according to the American Cancer Society.


The use of asbestos in building materials such as insulation, rolled roofing, siding and floor tiles was common in the first half of the 20th century, and if you have an older home, it may be lurking in your floor tiles. Before you panic, it's important to realize that the best course of action may be to simply leave the tiles alone. When encased in floor tiles that are in good condition, asbestos is not in a friable state and can't become airborne, but that isn't true if the tiles are cracked or damaged.

If your floor tiles or sheet flooring are actually linoleum, you have less to worry about than if they are another material. While asbestos is useful as a binding agent in the manufacture of vinyl and rubber floor coverings, it isn't needed to make linoleum tiles or sheet flooring. However, you're not completely in the clear because asbestos was a common ingredient in the mastic used to hold these flooring materials to the subfloor.

What Makes Asbestos Dangerous

Asbestos is a class of minerals known as hydrous magnesium silicates, and it exists in more than one form. Chrysotile asbestos, the most common form, consists of spiral fibers, while amphibole asbestos fibers are long and needle-like. Asbestos fibers are fire resistant and durable, and they can be woven into fabric or incorporated with other fabrics and materials to make them stronger.

When inhaled, the extremely thin fibers can stick to the throat, windpipe and bronchi and may be cleared by coughing and eventually swallowed. Some of the fibers, however, can make it to the lungs, where they lodge in the pleura, or outer lung lining, and cause irritation that eventually leads to cancer and other illnesses.

Where You Might Find Asbestos in the Home

The use of asbestos has been common in multiple industries throughout history and especially during the 19th and early 20th century. Besides being included in floor tiles, sheet flooring and tile adhesive, some of the purposes for which it was used included:


  • Cement, plaster and drywall joint compound
  • Wall, pipe and electrical insulation
  • Rubber door gaskets
  • Ironing board covers and pot holders
  • Wall texturing

If your home was built before 1980, there's a good chance some of the materials used to build it contain asbestos. This doesn't necessarily put you at risk, however. As long as the asbestos is locked into the material and can't become airborne, you're probably safe.

Asbestos in Linoleum and Vinyl Flooring

Because linoleum was invented long before vinyl, people often refer to both types of flooring as linoleum, but there's a big difference. Linoleum is an all-natural floor covering composed of dried linseed oil, wood dust, cork and jute, and it doesn't contain asbestos. Vinyl is a synthetic plastic, and manufacturers often included hefty amounts of asbestos for stability and fire resistance.

One Armstrong World Industries vinyl resilient sheet flooring product thought to have been installed in 1967 was tested in a lab and found to contain 70 percent asbestos. Such products, some sold under the brand name Solarian, were installed as recently as 1980, long after governmental restrictions on asbestos were initiated.

You can tell the difference between linoleum and vinyl by looking at the pattern. A vinyl pattern is obviously embossed on the surface, whereas a linoleum pattern extends all the way through the material, giving the flooring material a translucent depth. The type of pattern is often a dead giveaway. Linoleum patterns are often floral or geometric, but they are usually more basic than vinyl patterns due to the fact that they are created by pigmentation and not by embossing.

Is Removal Necessary?

Asbestos-containing materials can exist in one of two states: friable and nonfriable. Nonfriable materials are those in which the asbestos is locked and cannot become airborne. Resilient flooring is a nonfriable asbestos-containing material as long as it's in good condition, and as such, no immediate action is necessary.


The safest course of action is to leave the nonfriable flooring intact because any attempt to cut, scrape or otherwise remove it turns it into friable asbestos, a hazardous material. If possible, cover it with another layer of flooring. Laminate flooring or luxury vinyl tiles are two good options because they float on the existing floor and don't need to be glued or nailed.

Many older resilient floors have cracks, cuts and other damage. If the floor is true linoleum, damage does not present a danger of asbestos inhalation unless it extends all the way to the subfloor and exposes the mastic, which may contain asbestos. Older vinyl or rubber floors that are damaged are a different story because the tiles can release asbestos, so they need to be removed.

Even if the flooring isn't damaged, you may want to remove it for one of a number of other reasons. You may be undertaking a major remodel, or you may need to make modifications to the subfloor. Even if the vinyl and linoleum don't present the same danger of asbestos exposure, you should treat both types of flooring as if they do when it comes to removing them.

Can You Do It Yourself?

DIY asbestos removal is not recommended and can put you and others in your family at risk of asbestos exposure. Some states allow homeowners to remove asbestos inside the home themselves but not the exterior of the home, and some states place a limit on the square footage that can be removed without a permit. In California, the limit is 100 square feet, according to A Consumer's Guide to Asbestos, published by the Contractors State License Board.

Professional asbestos abatement is expensive, but it's also guaranteed. If you do the job yourself, there's a chance that you may track asbestos dust to other parts of the house or worse. Moreover, you may run afoul of state regulations regarding abatement and disposal if you don't do thorough research before you begin the project.

It's imperative to check with your local building department before undertaking any asbestos removal project. If no law prevents you from doing the job yourself and you do all the necessary research beforehand to ensure you do the job in compliance with local regulations, then you're good to go.

Procedure for Flooring Removal

Before you begin removing floor tiles or sheet flooring that contains asbestos, you must isolate the work area to prevent any dust raised during the cleanup from migrating to other parts of the house. You should also find a disposal site that accepts asbestos before you start so you know what you're going to do with the hazardous asbestos floor material. You can usually obtain a list of disposal sites from your local health authority.

Things You'll Need

Step 1: Isolate the Work Area

Cover all doors and windows with sheet plastic, leaving one entry to the work area through a slit that you can seal with duct tape. Move all furniture out of the cleanup space, or if you can't, seal it completely with plastic. Bring all your tools into the work area and leave them there for the duration of the procedure.

Step 2: Put on Protective Clothing and a Mask

Wear full-body protection, including a painter's suit, shoe protectors and gloves. Use a HEPA respirator with an N95 rating or better. Because there is little danger of breathing oily compounds, Major Safety advises that the more expensive R95 and P95 filters aren't necessary, but since they do offer more protection, you might consider using one.

Step 3: Disturb the Flooring as Little as Possible

Remove the first floor tile by wedging a rigid putty knife under the edge and tapping with a hammer. Gentle tapping is usually all it takes to pop it off the adhesive. Once the first tile is gone, you can use the putty knife at a more efficient angle to pop off the rest of the tiles.

Use a utility knife to cut sheet flooring into 6-inch-wide strips that extend the length of the floor. Work the putty knife under the end of each strip and pull up the strip gradually. Pour water on the strip to keep it wet and to prevent asbestos fibers from becoming airborne.


Step 4: Scrape Off Old Mastic

Wet down the mastic residue on the subfloor with plenty of water to emulsify it and prevent loose fibers from becoming airborne. Scrape it systematically with a putty knife or floor scraper. Be thorough because you can't go back and sand off what you don't remove with the scraper.


Do not attempt to remove the adhesive by sanding, grinding or otherwise abrading it. This is guaranteed to fill the air with enough asbestos fibers to put you at risk even if you're wearing a HEPA respirator.

Step 5: Stow All Waste Safely

Put waste tiles, sheet flooring and adhesive in boxes lined with plastic garbage bags for disposal. Do not simply put waste in plastic bags because the edges of sheet flooring and tiles can poke through the plastic. Store the waste safely in a secure location until you can take it to a disposal station.

Rubber Underlayment May Contain Asbestos

Some very old types of flooring that you may find in buildings that date back to the early 1900s have an attached rubber underlayment, and this underlayment may contain asbestos. This type of flooring is dangerous because old underlayment tends to become flaky and crumbly, and fibers can become airborne every time you sweep or vacuum with a non-HEPA vacuum cleaner.

The flooring may be stapled to the subfloor or it may be simply placed on top like a rug, and the underlayment may be attached to the flooring or independent of it. Either way, both the flooring and the underlayment have to go for your safety and that of your family.

Follow all the safety precautions you would take if you were removing flooring that is attached to the subfloor, including sealing the work area, wearing protective clothing and using a HEPA respirator. Cut the flooring into pieces and store the pieces in plastic-lined boxes for disposal.
