Recommended Uses
Perma-Patch Crack Sealant Mastic Gray is recommended for sealing wide cracks and joints, as well as repairing a large variety of distresses in cement and asphalt pavements. It is designed for large cracks and distressed surface areas too small for repaving yet too large for traditional hot-applied crack sealants.
- Pavement cracks or joints over 1.5 inches wide
- Potholes, utility cuts, manhole covers
- Spalls, pop-outs, and corner breaks
- Localized skin patch repairs
- Repairs prior to surface treatments
- Bridge approaches or faulted areas
- Depressed thermal cracks
Surface Preparation
Proper surface preparation facilitates adhesion and consequently the maximum service life of the mastic. In order for proper adhesion to occur, the surface must be free of moisture, dust, loose aggregate, and other contaminants. Avoid use in highly distressed areas that require reconstruction. The substrate and air temperatures must be 40 °F or above. Use oil-free compressed air and heat to clean and dry the area immediately prior to application. Heating the pavement will promote bonding between the mastic and pavement surface. Caution do not overheat/oxidize the pavement.
