How Exposure to Asbestos Popcorn Ceilings Bound to Cause Mesothelioma Cancer?
Asbestos Popcorn Ceilings: In numerous households across the United States, popcorn ceilings remain a prevalent feature. These textured drywall ceilings gained popularity between 1945 and the early 1990s.
Particularly, popcorn ceilings installed prior to the 1990s often contain asbestos, a fire-resistant mineral that was widely used in construction materials until the 1980s. Contact with asbestos in popcorn ceilings has been linked to the development of mesothelioma cancer.
Do Popcorn Ceilings Have Asbestos?
From 1945
to the early 1990s, asbestos popcorn ceilings gained popularity due to their textured
appearance, serving both as acoustic insulation and a method to conceal
imperfections. Unfortunately, these ceiling materials frequently incorporated
asbestos.
During
that era, asbestos was a prevalent component in various construction materials,
including popcorn ceilings. Its widespread use stemmed from its fire-resistant
properties, cost-effectiveness, and durability.
The
composition of popcorn ceiling coverings typically contained asbestos ranging
from one to ten percent.
What Does a Popcorn Ceiling Look Like?
- Surface displays visible pockmarked texture
- Colors commonly include white, off-white, or beige
- Variation exists in the depth of the "popcorn" effect
How Common Is Asbestos in Popcorn Ceilings?
Popcorn
ceilings and various products commonly used throughout the 20th century often
contained asbestos. Records suggest that popcorn ceiling materials installed
between 1945 and the early 1990s likely included asbestos.
The
Environmental Protection Agency (EPA) implemented the National Emission
Standards for Hazardous Air Pollutants (NESHAP) in 1973, prohibiting hazardous
substances in ceiling coverings.
Studies
indicate that asbestos might have persisted in asbestos popcorn ceiling materials even
after this regulation. Asbestos-containing inventories were exempt from the
ban, potentially leading workers to continue using them.
There are
some reports that suggest that stockpiles of asbestos-containing materials for asbestos popcorn ceilings might have remained until the 1990s.

When Did Companies Stop Using Asbestos in Popcorn Ceilings?
Popcorn
ceilings containing asbestos were a common feature from 1945 through the 1990s.
Although
asbestos was formally prohibited from ceiling coverings in 1973, products
manufactured earlier, which contained asbestos, might have still been installed
in residences until the 1990s
Individuals
who own homes built before the 1990s should assume asbestos is present in all
popcorn ceilings. Materials installed after 1995 likely did not contain
asbestos. Some other names for popcorn ceiling products include:
- Acoustic ceiling
- Blown-on ceiling
- Cottage-cheese ceiling
- Spray-on ceiling
- Stipple ceiling
- Stucco ceiling
- Textured ceiling
Should
these ceilings not have been replaced, residences and other structures might
still harbor asbestos within their materials.
If
homeowners believe their popcorn ceilings were installed before the early
1990s, it's advisable to engage a professional for testing, removal,
encapsulation, and proper disposal of any asbestos present.
Handling
asbestos should strictly be undertaken by certified asbestos contractors. Any
activities like sanding, painting, or patching of a popcorn ceiling might
disturb asbestos fibers, leading to the creation of hazardous asbestos dust.
In homes
with asbestos-containing ceilings, professionals may opt to either remove or
encapsulate the materials as deemed appropriate.
Asbestos
removal entails the meticulous elimination of asbestos-containing materials
from a building. A licensed professional manages this process, ensuring the
safe and legal disposal of the asbestos.
On the other hand, asbestos encapsulation involves covering or sealing asbestos-containing products to prevent the release of fibers into the air. This method aims to contain and prevent the dispersal of asbestos particles.

How to Test Your Ceiling for Asbestos?
If there's
suspicion of asbestos in a home, homeowners should avoid attempting removal or
encapsulation on their own and instead, engage a licensed abatement contractor
as the initial step.
If
asbestos materials might have been disturbed, taking preventive measures can
help minimize exposure. To prevent asbestos exposure before the arrival of abatement
professionals, homeowners can:
- Evacuate pets and individuals from the area
- Close all vents and doors in the affected zone
- Dampen the area to prevent airborne fiber release
Entrusting
asbestos handling to professionals is the safest approach, safeguarding friends
and family from inhaling hazardous asbestos fibers.
Regarding testing your ceiling for asbestos, a professional asbestos testing service can accurately determine the presence of asbestos in your ceiling materials.

How to Remove Popcorn Ceilings With Asbestos?
A licensed
asbestos abatement contractor is the appropriate professional to handle
asbestos removal. It's crucial for homeowners, landlords, tenants, or general
contractors to avoid attempting removal themselves.
Contractors
assessing asbestos in ceilings consider its condition and friability—the degree
of "crumbliness" of the material. Highly friable asbestos products
pose the most significant risk as they're more likely to release fibers into
the air, often necessitating removal by professionals.
In cases
where low friability products are in good condition, encapsulation might be
recommended by contractors.
For a
comprehensive asbestos popcorn ceiling removal, the contractor typically
initiates by shutting off ventilation to the affected area. Wetting down the
products helps prevent the release of airborne fibers during removal.
Disposal
of asbestos products adheres to state regulations, with licensed contractors
ensuring the safe disposal of these materials to prevent harm to others.
The Dangers of Asbestos in Popcorn Ceilings
Please
note that disturbed or damaged asbestos popcorn ceilings have the potential to
release harmful fibers into the air.
Inhalation
or ingestion of these asbestos fibers poses significant health risks. Once
asbestos enters the body, it can lead to the development of severe health
conditions over time.
Health Risks of Asbestos Exposure from Popcorn Ceiling
Asbestos
fibers have the potential to embed themselves within the linings of internal
organs, leading to prolonged irritation and scarring over time.
This
irritation can result in several hazardous health conditions, the most severe
being mesothelioma cancer. Other associated illnesses include asbestosis and
asbestos-related lung cancer.
In a
specific case study, researchers investigated the exposure of a woman who lived
in a residence with asbestos ceilings for three decades. Ongoing water damage
caused the release of asbestos dust into the air. The individual began
experiencing severe coughing spells in the 1990s. By 2010, she received a diagnosis
of lung cancer and subsequently displayed lung scarring consistent with
asbestosis.
Asbestos-related
diseases may take anywhere from 10 to 50 years to manifest after initial
exposure. While there's no identified safe level of asbestos exposure, repeated
or prolonged exposure might elevate the risk of developing an asbestos-related
disease.
Who Is
Most at Risk From Asbestos Popcorn Ceilings?
Today, a
number of groups face different levels of risk regarding contact with asbestos
in popcorn ceilings:
- Construction
Professionals: Those involved in construction, renovation, or demolition work
are at occupational risk of encountering asbestos in popcorn ceilings.
- Homeowners
and Families: In residences with asbestos-containing popcorn ceilings, entire
families might be exposed to the mineral. Removal or encapsulation of these
ceilings can help mitigate asbestos exposure at home.
- People in
Close Proximity to Asbestos Workers: Individuals living or working closely with
those handling asbestos have a heightened risk of exposure. Secondary exposure
can occur through contact with someone who has asbestos fibers on their
clothing or body. For instance, spouses of asbestos workers might face this
risk.
- Owners of older homes, in particular, should consider testing popcorn ceilings and other materials for asbestos content. Professionals can conduct tests and recommend suitable mitigation plans to prevent potential exposure.
