Description

Perma-Patch Crack Sealant 3405 is a premium crack and joint sealant for Portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, Perma-Patch Crack Sealant 3405 prolongs pavement life by sealing cracks and joints from water penetration, which causes base failure and potholes. Perma-Patch Crack Sealant 3405 is a hot-applied, one-part material that provides excellent results in cold weather and throughout repeated freeze/thaw cycles. Perma-Patch Crack Sealant 3405 offers high resiliency, ductility, and resistance to weathering. Perma-Patch Crack Sealant 3405 forms a long-lasting seal that resists tracking in warm temperatures and remains flexible in cold temperatures.

Recommended Uses

Perma-Patch Crack Sealant 3405 is recommended for sealing cracks and joints 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. In order 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 prior to 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.
