What is Marblesheen/Marblelite?
Marblesheen also known as Marblelite is a decorative coating applied to the surface of concrete pool shells with the average thickness between 5-25mm. It is primarily composed of white cement and white marble chips between 1-2mm in diameter. If the Marblesheen coating was applied prior to 1990, it may include asbestos.

How Do I Identify If A Pool Coating Contains Asbestos?
The only way to confirm if a Marblesheen coating contains Asbestos is to have a sample analysed by a National Association of Testing Authority accredited laboratory.
Is There A Risk Of Exposure To Asbestos From Marblesheen Coatings?
If the Marblesheen coating is in good condition and left undisturbed, it presents as low risk as it is non-faible and the asbestos fibres are bound to the cement. However if the surface is deteriorated in the way of cracks, breaks and chips or delamination of the coating there may be a risk.
Maintenance, Renovation Or Demolition Of Marblesheen Containing Asbestos
Any work involving the removal of disturbance of Marblesheen coatings assumed or confirmed to contain Asbestos must be done in accordance with the Work Health and Safety Regulation 2011.
