When we think of asbestos, most of us picture old buildings, insulation, or perhaps roofing materials. However, asbestos-containing materials can be found in some surprising places, one of which is marble sheen used in pool coatings. Despite the common perception of swimming pools as safe and leisure-friendly environments, they can sometimes harbor hidden dangers, particularly in older constructions.
What is Marble Sheen?
Marble sheen is a type of pool plaster that provides a smooth and durable finish for swimming pools. It’s valued for its aesthetic appeal, offering a luxurious and polished surface that enhances the look of the pool. Traditionally, marble sheen has been made from a mixture of white cement and crushed marble. This combination creates a strong, waterproof layer that can withstand the harsh conditions of constant water exposure.
The Asbestos Connection
In the mid-20th century, asbestos was commonly used in various building materials due to its fire-resistant properties and durability. Unfortunately, it was also added to some marble sheen formulations used in pool coatings. Asbestos fibers were mixed into the plaster to increase its strength and longevity. While this might have seemed beneficial at the time, we now know that asbestos poses significant health risks, particularly when the fibers become airborne and are inhaled.
Health Risks Associated with Asbestos
Asbestos is a known carcinogen. When asbestos-containing materials deteriorate or are disturbed during renovations, the fibers can become airborne and inhaled, leading to serious health conditions. The most notable of these conditions is mesothelioma, a rare and aggressive form of cancer that affects the lining of the lungs, abdomen, or heart. Asbestos exposure is also linked to lung cancer and asbestosis, a chronic lung disease.
How Can Asbestos in Marble Sheen Affect You?
If your pool was constructed or resurfaced before the 1980s, there is a chance that asbestos could be present in the marble sheen coating. Over time, as the pool surface wears down due to regular use, cleaning, or exposure to chemicals, the risk of asbestos fibers being released increases. Renovations, repairs, or even deep cleaning of older pools could disturb these materials, potentially releasing hazardous fibers into the air.
What Should You Do?
If you suspect that your pool’s marble sheen might contain asbestos, it’s crucial to have it tested by a professional. Asbestos testing involves taking a small sample of the material and analysing it in a laboratory. If asbestos is detected, do not attempt to remove or repair the surface yourself. Instead, contact a licensed asbestos removal specialist who can safely manage the situation according to regulatory guidelines.
We have managed several projects involving the demolition or relining of pool coatings. These tasks are performed under friable asbestos removal conditions and often involve navigating very tight access areas.
Conclusion
The presence of asbestos in marble sheen pool coatings is a little-known risk that can have serious health implications. Awareness is the first step in managing and mitigating this danger. If your pool is older, especially if it dates back to a time when asbestos was widely used, consider getting it tested. Ensuring the safety of your pool environment is essential not just for the aesthetics and functionality of the pool but also for the health and well-being of those who use it.
