SEALTIGHT MASTIC is a hot-applied, aggregate-filled, polymer-modified pavement repair product. SEALTIGHT MASTIC is used for repairing distresses in asphalt cement and portland cement pavements that are larger than those typically repaired with crack or joint sealers. When properly applied, SEALTIGHT MASTIC forms a flexible, durable, and traffic-resistant bond to asphalt or concrete pavements.

All technical data is typical information and will vary due to testing methods, site conditions, temperature, curing, procedures and batching. Statistical differences in test results should be anticipated. Onsite testing results may not correlate to published laboratory results due to testing variations from laboratory conditions.
APPLICATION
Surface Preparation … The areas to be sealed must be clean and dry. Dust, dirt, and laitance should be removed prior to application.
Application Method … Place SEALTIGHT MASTIC into an appropriate melter and then mix and heat until application temperature is reached. SEALTIGHT MASTIC is then poured into the repair area and leveled. The repair area can be opened to traffic immediately after cooling.
PRECAUTIONS
Service life at recommended temperatures is approximately 12 – 15 hours. SEALTIGHT MASTIC can be reheated once within the prescribed safe heating temperature limits. Repeated reheating may result in material degradation.
