About this file
This document is a Technical Data Sheet for CrackMaster Mastic PL-CPT, a pavement repair product manufactured by SealMaster, a pavement products and equipment company. The technical data sheet, revised on 07/10/23 and labeled as SMT-273, provides detailed specifications and application instructions for a hot-applied repair mastic designed for road and pavement maintenance.
The product is a black asphalt-based polymer-modified mastic designed for sealing wide cracks and joints in cement and asphalt pavements. It is specifically recommended for pavement cracks over 1.5 inches wide, potholes, utility cuts, manhole covers, spalls, and localized repairs. The mastic is heated to 375-400°F for application, requires no compaction, and provides a high-friction surface for driver safety. It is packaged in 45 lb. poly-bags or meltable boxes, with pallets containing 60-64 boxes (2,700-2,880 pounds of mastic). The product offers excellent adhesion, rapid melting, and resistance to tracking, and is formulated to perform in all climates with a warranty that only covers replacement of the product itself.

Technical Data Sheet
PRODUCT DESCRIPTION
CrackMaster Mastic PL-CPT is a hot-applied repair mastic comprised of a black asphalt based polymer modified binder and select aggregate. This material is self adhesive.
CrackMaster Mastic PL-CPT resists cracking, delamination, and spalling. It is a flexible material that can withstand heavy loads, weather, traffic and thermal movement. Mastic provides a high-friction surface to ensure driver safety. Compaction equipment is not necessary with CrackMaster Mastic PL-CPT.
This repair system is formulated to provide a feathered edge.
| • | Excellent Adhesion |
| • | Rapid Melting |
| • | Resists Tracking |
RECOMMENDED USES
CrackMaster Mastic PL-CPT 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 re-paving yet too large for traditional hot applied crack sealants.
Ideal Uses:
| • | 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 contaminates.
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 to overheat/oxidize the pavement.
MELTING AND APPLICATION
Melt CrackMaster Mastic PL-CPT using an oil-jacketed kettle designed for mastic materials. The kettle should be equipped with an agitator and temperature control devices for the material and heating oil. Carefully insert small quantities of CrackMaster Mastic PL-CPT and the plastic bag into the melter while the agitator is turned off to avoid splash back. Once material has reached application temperature, apply to freshly prepared area. CrackMaster Mastic T2-CPT can be applied directly from the melter using an appropriate discharge chute, bucket, or mastic wagon. Immediately following application, the mastic shall be leveled and smoothed using mastic lutes. In deep installations, mastic may be applied in layers, cooling in between. When mastic is installed where added skid resistance is desired, CrackMaster Mastic PL-CPT can be covered with a surface aggregate. CrackMaster Mastic PL-CPT is ready for traffic when it has cooled and solidified.
NOTE: The temperature of the heating oil should not exceed 525 °F. Do not heat material over the maximum heating temperature. This could cause the material to gel in the equipment or fail on the pavement. A significant viscosity increase accompanied by stringiness signals the approach of gelation. If this occurs, immediately remove the material from the melter and dispose of it.
PACKAGING
CrackMaster mastics are packaged in 45 lb. poly-bags in a high-strength, corrugated box with each pallet containing 60 boxes or 2,700 pounds of mastic. CrackMaster mastics are also available in 45 lb. meltable boxes with each pallet containing 64 meltable boxes or 2,880 pounds of mastic.
