A method for reducing leakage of bodily fluids or air through lung tissue within a patient is provided. In one embodiment, the method comprises applying, to an appropriate area of lung tissue, an adhesive composition that is derived from a mixture of KH2PO4, metal oxide, a calcium compound, and water, wherein the weight percent ratio of KH2PO4 and the oxide is at least approximately 1:0.5. The method also comprises polymerizing the adhesive composition to form a sealant that substantially seals the body area with a coating.
