The sheet flooring shown above and illustrated further just below was identified by a reader in a 1964 home. She found remnants in the bottom of a kitchen cabinet on which was imprinted "Armstrong". The reader asked "Is it linoleum?" A closer look at the product including its backing would be needed. It could be, but this pattern looks more modern to us and is very probably an Armstrong vinyl sheet flooring product. More information about this marble chip pattern sheet flooring is given just below.

The sheet flooring photograph shown above, provided to us by a reader, was tested for asbestos content. Our reader reports:

The house where this sheet flooring is installed was built in 1966 to 1967. We assume this was the original flooring put down by the previous owner who built the house - we are the second owners of this home. There was no other flooring under or on top of this, and there is no sign of other layers of flooring below it, so I think it's safe to assume they put it down in 1967. There is no way to know brand since its on bottom, and we haven't removed the floor covering.

We did have the linolium tested and it was positive for 15% chrysotile. Just thought you may want to add this for your catalog. As such we will just leave it undisturbed and cover over with hardwood. - Anon, by private email 10/21/2015

Note: Although many people refer loosely to resilient sheet flooring as "linoleum", the sheet flooring above is a vinyl product and is distinct from true linoleum floors. Linoeum floors do not contain asbestos.
See LINOLEUM & SHEET FLOORING for details about that product.

If the vinyl resilient sheet flooring backing material were dry-sanded or scraped during building demolition, for example, or if the sheet flooring is worn through so that foot traffic continues to damage the backing material, it is possible for unsafe levels of asbestos fibers to be released in a building. --EPA Guidance

During demolition or removal, this material should be disturbed as little as possible. Additional demolition, renovation, and installation advice for dealing with resilient sheet flooring materials can be obtained from the Resilient Floor Covering Institute, by obtaining their publication on the topic.

Asbestos in Armstrong Sheet Flooring 1930's - 1980's

At ASBESTOS FLOOR TILE IDENTIFICATION PHOTOS by YEAR we include a reader report of lab testing performed on this flooring and confirming that it contained "70% asbestos". While the reader referred to this as "Armstrong Congoleum sheet flooring", Armstrong and Congoleum are separate individual companies. The flooring shown just above is identified as an Armstrong resilient flooring product.

Armstrong Sheet Flooring Identification & Brand Markings

Below are two more identification photographs of the same flooring contributed later by reader R.B. who shows us the Armstrong® imprint on the reverse side of this product [photo at below right]. This confirmed the flooring brand: Armstrong.

Don't mix up product names. Armstrong is a separate company from Congoleum-Nairn. Both companies produce several types and many patterns of sheet flooring. As we discuss at CONGOLEUM FLOORING HISTORY, Linoleum flooring advertised in 1955, here the Congoleum Gold Seal series, was sold in both sheet and tile forms.

Shown below is very similar but more rectangular marble-chip type sheet flooring contributed by a reader - August 2015.

OK so we ran out of space and had to move the details of this topic.

Please see SHEET FLOORING BRICK PATTERN ID (separate article)

If the flooring has what looks like burlap - a jute backing - on its reverse it's probably very old and not an asbestos-containing product.

If it has a smooth, non-fabric backing it may contain asbestos and should be treated as PACM - presumed asbestos containing material. From your photo (above left) this looks like a very-widely used sheet flooring with an impregnated asphalt felt backer - let me know. Some such felt backers included asbestos. As we report below, a reader obtained an asbestos test lab report on a sample of flooring that looks like that above: the lab did not report finding asbestos in that sample.

Don't panic, just don't create a dusty mess by using power tools, saws, grinders;

Watch out that the mastic used to adhere old sheet flooring may also contain asbestos. After trying various solvents on a black mastic years ago I discovered that it was water soluble and came up easily once I let it sit wet for a few hours. Try that.

J.W. Indeed I've found other similar flooring patterns to those in your photo that by date, records, tests, were confirmed as having asbestos in the vinyl backing; it would be prudent to treat the material as presumed-asbestos-containing material. Don't panic; non-friable materials like this can usually be handled with a minimum of dust and debris - provided the floor was not glued down.

The flooring shown at above left, installed in the 1980's did not contain asbestos. Details are at SHEET FLOORING BRICK PATTERN ID

The flooring shown at above right in a white brick pattern (these are tiles not sheet flooring) contained asbestos.

If you are facing a large cost or have other reasons to be concerned about asbestos contamination in the building it would not be costly to have a small sample of the floor tested. The advice at these 3 articles should be helpful.

Question: Test Results for Armstrong Sheet Flooring - 70% Asbestos

Vinyl asbestos sheet flooring (C) InspectApedia.com

The resilient flooring shown above was a popular pattern and has been confirmed as containing asbestos. This is an Armstrong brick pattern sheet flooring product. More images of this floor pattern are at ARMSTRONG BRADFORD BRICK SHEET

Armstrong sheet flooring (C) InspectAPedia.comIn one of the asbestos pages of your site ( this page - Ed.), your second photo is of a sheet layment. The text about the photo clarifies that the person who sent the photo was confused about Armstrong and Congoleum.

I wanted to let you know that I have that exact same sheet layment and had it tested. It's 70% asbestos. Thought you may want to let readers know so they can save the cost of testing and just deal with the issue accordingly.

I appreciate your site. Thank you for taking the time to put together all the information. - D.H. 10/11/2012

Reader question:

Attached are photos of some tile removed from my basement. I believe the backing says it is Armstrong brand tile. I can't find anything in your database about whether this contains asbestos but I have a small child in the house ... I wanted to check. Any information would be greatly appreciated. - Anonymous by private email 2016/06/21 Jake Barrett jakebarrett78@yahoo.com

This flooring may be a rubber-backed product and may contain asbestos. Our research, cited below, confirms that some Armstrong flooring products included an asbestos-containing rubber-backing material. (Whitman 1975 et als). I have also seen older asphalt-backed sheet flooring products in similar designs.

Lab test results for asbestos in the Armstrong red-backed (probably rubber) flooring shown above are pending (June 2016). This floor covering was found in a U.S. home dated ca 1900.

If you avoid making a dusty mess such as by vacuuming with a non-HEPA-rated vac, chopping, grinding, sanding, chances are you're not stirring up measurable dust, asbestos or not.

If you search InspectApedia.com for ASBESTOS FLOORING HAZARD REDUCTION you'll see more suggestions for minimizing risk.

We speculate that this Armstrong rug-pattern red-backed sheet flooring dates from the 1940's. Below: a view of the red-colored back of this floor covering. This may be a rubber-backed sheet flooring product similar to some red-backed Congoleum flooring of the same era.

Research on Asbestos in Armstrong Rubber-containing Flooring Products or Rubber-Backed Flooring

Armstrong World Industries, earlier Armstrong Cork Co., has a long history in the production of an enormous range of types and designs of floor coverings. Armstrong's flooring literature including for its current commercial flooring products and floor cleaning products includes "rubber tile" and stair treads, rubber wall base, as well as "linoleum" in product descriptions. Armstrong points out in the company's current floor maintenance instructions:

It is important to know the type of floor before cleaning. Rubber or linoleum could be confused with vinyl or luxury vinyl tile (LVT) could be confused with wood or laminate. - Armstrong World Industries, "Maintenance Recommendations and Procedures, Commercial Resilient / Hardwood / Laminate", [PDF], Armstrong Corporation, retrieved 2016/06/21, original source: http://www.armstrong.com/assets/commflooringna/literature/downloads/F8663.pdf
