CrackMaster TRM is a hot pour crack and joint sealant for portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, CrackMaster TRM prolongs pavement life by sealing cracks and joints from water penetration, which cause base failure and potholes. This is a high viscosity, non self-leveling material with a crumb rubber content of 18% minimum based on asphaltic components or 13% minimum by overall weight. CrackMaster TRM forms a long-lasting seal which resists tracking in warm temperatures and remains flexible in cold temperatures.
CrackMaster TRM is recommended for sealing cracks and joints in portland cement, asphaltic pavements, and parking lots. It is designed to seal expansion and contraction joints, longitudinal and transverse cracks, joints between concrete and asphaltic shoulders, and random cracks.
Use material as supplied. Do not blend with other materials. After CrackMaster TRM is melted it should be agitated or recirculated.
Apply heated CrackMaster TRM 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.
