Abstract
A process for coating geological formations and mine stoppings by applying to these substrates an aqueous, non-cementitious sealant composition comprising a water-soluble or water-dispersible polymeric binder, filler material and water, and allowing the sealant composition to dry to form an air flow resistant coating on the substrates. A highly satisfactory polymeric binder is used in the form of a polymer emulsion, such as an emulsion of an acrylic polymer having a low Tg and being sufficiently plasticized to provide a coating having prolonged air flow resistance.
