A novel sealant composition is disclosed which comprises approximately 50 to 80 parts by volume of an asphaltic emulsion, approximately 20 to 50 parts by volume of a copolymer prepared by the copolymerization of a vinyl acetate monomer with an organic acid and approximately 0.5 to 2.0 parts by volume of nonionic surfactant having a hydrolyptic balance from approximately 11 to 14. The sealant composition is adapted to seal asphalt, cement, roofs and metal, among other things.
