How to Cover Asbestos Pipe Insulation
Asbestos is a material that used to be used as a fire retardant insulation for buildings, pipes, roofs and attics. It was discovered in the late 70s that those with significant asbestos exposure were more likely to get certain forms of cancer, such as Mesothelioma. Many homes have asbestos tainted materials somewhere within them. Removal is not always the best option. For small amounts of asbestos, such as asbestos pipe insulation, you can encapsulate, or seal it to reduce any health risks. Asbestos is only dangerous as it deteriorates due to the asbestos fibers that break off, spread through the air, and attach themselves to the mucus lining of your lungs and other organs. Sealing asbestos is a safe alternative. Does this Spark an idea?

Secure the ventilator firmly around your mouth and nose. Tighten the straps to ensure an air-tight fit.

4
Paint the encapsulant onto each pipe.

Allow to dry for 60 minutes. It should be dry to the touch within 30 minutes, but pipes often heat and cool quickly, thus slowing the dry time of the encapsulant closest to the pipe.

Tips & Warnings
Do not attempt to encapsulate insulation that is in poor condition. The fibers are the most dangerous part of the asbestos, and when you have insulation that is in poor condition and flaking off, it spreads fibers throughout the house. Only attempt to encapsulate asbestos insulation that is in good condition.
Do not use duct tape as an alternative to asbestos sealing tape. It doesn't provide the same seal.
