Coverage
Use the following chart as a guideline for estimating material requirements (based upon pounds of material needed for 100 feet of cracks):
| Crack Width | Depth | lbs. / 100 ft |
| 3/8″ | 3/8″ | 6.9 lbs. |
| 1/2″ | 1/2″ | 12.3 lbs. |
| 3/4″ | 3/4″ | 27.8 lbs. |
NOTE: The above coverage rates are only a guideline. Actual material usage may vary due to width of application and thickness of material above pavement surfaces.
Description
CrackMaster 3405 LM is a single component, low-modulus, hot applied crack and joint sealant specifically designed for low temperature flexibility down to -40°F. When melted and properly applied it forms a resilient crack sealant for both asphaltic and cementatious pavements. Meets state modified ASTM D 3405, and ASTM D6690 Type IV. Exceeds ASTM D1190, AASHTO M173, Fed. Spec. SS-S-164 and AASHTO M301.
Uses
CrackMaster 3405 LM is designed to seal expansion joints, longitudinal and transverse cracks, joints between concrete and asphalt shoulders, and random cracks in both asphalt and concrete pavements.
Mixing Procedures
Use material as supplied. Do not blend with other materials. After CrackMaster™ 3405 LM is melted it should be agitated or recirculated.
Application
Apply heated CrackMaster 3405 LM using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e. 2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8″ above surrounding pavement. Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.
Important
Protective apparel is recommended with application of CrackMaster 3405 LM. The extremely hot material will cause severe burns on contact with skin. OSHA Safety Regulations require workers to wear the following types of safety attire (see current OSHA/Safety Regulations for additional information): Hard hat with face shield; long sleeved shirt buttoned at the wrist; heat resistant gloves; long, cuffless pants; and safety toed work boots. Make certain all area around melter is clear of all debris and flammable materials. Avoid breathing vapors. Use with adequate ventilation.
Clean Up
Wash tools in water before material dries.
