Sealmaster Crackmaster Supreme Description
CrackMaster™ Supreme is a single component, hot-applied, rubberized asphalt crack and joint sealant. CrackMaster™ Supreme is specially formulated for both direct fire and oil-jacketed melters. It is heat stabilized to withstand temperatures up to 450°F without experiencing polymer degredation. When melted and properly applied it forms a resilient crack sealant for both asphaltic and cementatious pavements. CrackMaster™ Supreme meets manufacturer’s specifications.
Crackmaster Supreme Uses
CrackMaster™ Supreme 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. CrackMaster™ Supreme is relatively hard and has a high softening point, which makes it well suited for parking lots and driveways.
Mixing Procedures – Use material as supplied. Do not blend with other materials.
Crackmaster Supreme Coverage
Use the following as a guideline for estimating material requirements – (based upon pounds of material needed for 100 feet of cracks)
- Crack depth – 3/8 inch – Crack Width – 3/8 inch – Pounds per 100 ft. = 6.2
- Crack depth – 1/2 inch – Crack Width – 1/2 inch – Pounds per 100 ft. = 11.1
- Crack depth – 3/4 inch – Crack Width – 3/4 inch – Pounds per 100 ft. = 25
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.
Crackmaster Supreme Application Procedure
Apply heated CrackMaster™ Supreme 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™ Supreme. 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.
