Description

A premium quality crack and joint sealing material that resists tracking at elevated temperatures and remains flexible down to -10°F. When melted and properly applied it forms a resilient crack sealant for both asphaltic and cementatious pavements. CrackMaster™ 3405 forms a lasting seal that resists tracking in warm climates.

Uses

CrackMaster™ 3405 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. It is ideally suited for parking lots.

Mixing Procedures

Use material as supplied. Do not blend with other materials. After CrackMaster™ 3405 is melted it should be agitated or recirculated.

Application

Apply heated CrackMaster™ 3405 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. 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.
