Sealant packaging and method
An improved sealant packaging and method for use with sealing joints and cracks in pavement and parking lots is provided. Liquid sealant material is poured by volume into a container draped with a sheet. Container is cooled so that the sealant becomes a solid block, with the sheet adhered to the sides of the sealant block such that the sheet forms a container for the sealant. The sheet also acts a release liner for easily removing the sealant block from the container. Two or more contained blocks are stacked together, forming a package of two or more blocks self-sealed by sheets. When the package is placed in a melting kettle, heat migrates through the spaces between the individual sealant blocks and allows the smaller sealant blocks to melt quickly and evenly. Sheet and film melt with sealant material and are incorporated therein to form the final sealant product.
