Aerosol Body Deadener may also be used as a coating for iron roofs, fibre roofs, inside guttering, downpipes, water tanks and on metal structures. Aerosol Body Deadener is also suitable for damp-proofing concrete and masonry walls, above and below grade, where no hydrostatic pressure exists. Once dry, Aerosol Body Deadener forms a durable, flexible, weather-resistant barrier. Although Aerosol Body Deadener may be used on water tanks, it is not recommended for the inside of tanks in which potable water is stored.
