ABSTRACT:
An improved asphaltic material useful for sealing or patching of porous, interstitial substrates such as concrete or asphalt is provided which achieves superior results by flowing into and at least partially filling the substrate interstices themselves, as opposed to serving merely as a surface coating. The material preferably includes a conventional CRS-1H cationic asphaltic emulsion, respective quantities of a vinyl acrylic copolymer and a NEOPRENE latex. In one type of sealing application, a diluted quantity of the asphaltic material is heated to about 160.degree. F. and is flooded over the substrate to be sealed; the liquid passes into and fills the substrate voids, and, after hardening of the material, an effective, gasket-like seal for the substrate is presented which retains its integrity during varying ambient weather conditions and under hard use.
