Description

Perma-Patch Crack Sealant 1190 is a hot pour crack and joint sealant for Portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, Perma-Patch Crack Sealant prolongs pavement service life by sealing cracks and surface joints from water penetration which causes base failure and pot-holes. Perma-Patch Crack Sealant 1190 is a single-component mix of asphaltic resins, synthetic polymeric rubbers, plasticizers, stabilizers, and a blend of organic and inorganic reinforcing fillers. When properly melted and applied, it forms a resilient and adhesive compound for both cement and asphaltic pavements. Perma-Patch Crack Sealant 1190 forms a long-lasting seal that resists tracking in warm temperatures and cracking in cold.

Recommended Uses

Perma-Patch Crack Sealant 1190 is recommended for sealing joints and cracks in Portland cement and asphaltic pavements. It is designed to seal expansion and contraction joints, longitudinal and transverse cracks, joints between concrete and asphaltic shoulders, and random cracks.

Surface Preparation

Proper surface preparation facilitates adhesion and consequently the maximum service life of the sealant. For proper adhesion to occur, the crack/joint must be free of moisture, dust, loose aggregate and other contaminates. The substrate and air temperatures must be 40°F or above. Sawing, routing, and/or sandblasting are the preferred methods of preparation. Use oil-free compressed air and heat to clean and dry the crack/joint immediately before sealing. Cracks/joints should be sized so that the maximum extension and compression do not exceed 50% of the width. Best results are obtained when the cracks/joints are opened at least ½ inch wide.
