Asbestos Siding Conundrum: Painting Over Or Removing?

Painting a house with asbestos siding is generally considered safer than removing it. Asbestos siding is durable and paint adheres to it well, meaning it can last for decades without chipping or cracking. However, there are still some precautions to be aware of when painting asbestos siding. It is important to avoid power-washing asbestos siding as this can release dangerous asbestos fibres into the air. Instead, a garden hose, sponges, and manual scrubbing with a brush and detergent are recommended. When painting, it is best to wear disposable coveralls and a respirator mask to avoid inhaling any asbestos fibres.

Painting asbestos siding is safer than removing it

Painting asbestos siding is generally considered safer than removing it. Asbestos-cement siding is a thin type of siding shingle made from a mixture of Portland cement reinforced with asbestos fibres. Asbestos was added to the cement as a binding agent to lend strength to the material. It is fireproof and can help limit or stop the spread of fires.

However, when asbestos-containing materials are disturbed through sawing, sanding, ripping, or demolition, the fibres become airborne. Asbestos poses a health risk if inhaled or ingested. Removing asbestos siding can be more hazardous than leaving it in place. If left alone, asbestos-cement siding and other building products containing asbestos can be considered benign.

Painting asbestos siding is a safer alternative to removal. Paint adheres well to asbestos siding and can last for many years without chipping or cracking. Painting also prevents deterioration and seals the surface, helping to stop dangerous asbestos fibres from becoming airborne. Fresh paint also enhances your home's appearance while reducing the risk of water damage.

When preparing to paint asbestos siding, it is important to avoid power-washing or pressure-washing, as this can chip or damage the siding and release asbestos fibres into the air. Instead, use a garden hose, sponges, and elbow grease to clean the surface. It is also recommended to wear protective gear, such as disposable coveralls and a respirator mask, during the cleaning and painting process.

In summary, painting asbestos siding is safer than removing it because it minimises the risk of disturbing and inhaling asbestos fibres. Proper preparation and safety precautions are crucial to ensure a successful and safe painting project.

Power-washing asbestos siding can release dangerous asbestos fibres

If you decide to power-wash asbestos siding, it is important to take the necessary precautions to minimise the risk of fibre release. Use a gentle touch and stop if you notice any pieces of siding being knocked off. It is also recommended to wear a respirator and disposable protective clothing to protect yourself from potential asbestos exposure.

Before power-washing, consider alternative methods for cleaning and prepping the siding, such as using a garden hose, sponges, and manual scrubbing. These methods may be more time-consuming, but they are safer and can effectively clean the surface without releasing asbestos fibres.

Additionally, be mindful of the surrounding area during power-washing. The released asbestos fibres can settle on nearby surfaces, such as cars or gardens, posing a risk to others. Contain the work area as much as possible and ensure that no one is in the immediate vicinity during the power-washing process.

If you are unsure about power-washing asbestos siding or have concerns about the potential risks, it is best to consult with local authorities or experts in asbestos handling and removal. They can provide specific guidelines and recommendations based on your location and situation.

Asbestos siding is very durable and it's difficult for fibres to become airborne

Asbestos siding is a protective material made of cement and asbestos that is added to the exterior of houses. Asbestos siding is very durable, and it is hard for its fibres to become airborne. The siding is resistant to fire, electricity, corrosion, and weather damage. It is also a good insulator, increasing energy efficiency, and is insect-proof.

Asbestos siding is very durable. It is resistant to fire, weather, and other damage. It is also a good insulator, increasing energy efficiency, and is insect-proof. Because of these benefits, asbestos siding was very popular before the 1980s.

However, asbestos is a known carcinogen, and disturbing it can release dangerous fibres into the air, which can be inhaled and cause serious health issues. Therefore, if you are painting asbestos siding, it is best to avoid power-washing, which can chip or damage the siding and release asbestos fibres. Instead, use a garden hose, sponges, and manual scrubbing to clean the surface.

Overall, while asbestos siding has its benefits, it is important to take precautions when handling it to avoid disturbing the asbestos fibres and causing potential health risks.

There is no right paint for asbestos siding

Painting asbestos siding is a much better alternative than removing it. Paint adheres easily to asbestos siding, and it is very durable. However, there is no "right" paint for asbestos siding. It does not require anything out of the ordinary.

You should pick a good-quality exterior paint from a reputable company, such as Benjamin Moore or Sherwin-Williams. Avoid cheap paint, as it will likely fail and not hold up. Painting asbestos siding is no different from painting any other exterior surface exposed to the elements.

If you are concerned about health risks, you can dispose of any clothing used during the painting process. This will eliminate the risk of bringing asbestos fibres into your home. Additionally, if you hire a contractor, painting asbestos siding does not require any special licensing.

Removal or abatement of asbestos siding can be very expensive

The type of asbestos can also influence the removal cost. While chrysotile accounts for 95% of the asbestos used in buildings in the US, other types such as amosite and crocidolite can be more expensive to remove due to their higher health risks. The condition and accessibility of the asbestos-containing materials also play a role in the removal cost. For instance, removing asbestos from hard-to-reach areas like the roof or attic can be more expensive.

In addition to the removal costs, there are also testing, labour, equipment, and disposal fees associated with asbestos abatement. Testing for asbestos typically costs between $250 and $850, while labour costs can range from $75 to $200 per crew member. Disposal fees for asbestos range from $10 to $50 per cubic yard, and a disposal permit is usually required, which can cost around $50 to $100.

Given the high costs and health risks associated with asbestos removal, repairing or encapsulating asbestos siding may be a more cost-effective option. Encapsulation involves creating an airtight seal around the asbestos to prevent the release of fibres and typically costs $2 to $6 per square foot. Repair projects for asbestos siding can average $4,770, with costs ranging from $690 to $9,430.
