A product and method for sealing cracks in pavements, roofs, or the like utilizes a can containing a tar sealant. The tar sealant is a solid at room temperature and assumes a fluid state pourable from the can when the tar sealant is heated in the can to a temperature above the melting temperature of the tar sealant. A spout and handle that can withstand the heat are fitted to the can for pouring the melted tar sealant in a fluid state from the can into a crack to be sealed.
