Thermoflex™ Crack/Joint Themo-Sealant
Thermoflex is a premium, single component, hot applied, asphalt/rubber joint and crack sealant. Furnished as a solid, it is an elastomeric sealant which is compatible with and bonds aggressively to clean and dry concrete or asphalt pavements. It is designed to be effective in a wide range of climates. It is a true direct fire product capable of being reheated and is especially effective under sealcoats, slurry seals and overlays because it will not bleed through.

Application
- Install heated sealant directly into cracks/joints not to exceed a 4 inch wide band. Thickness should be controlled to not more than 1/8 inch above pavement surface. Finished sealed cracks and joints will be uniformly level. Refill to achieve a flush to 1/8 inch concave surface appearance. One pound of PLS will fill the following lineal feet:

- Methods
Thermoflex should be heated in a vessel designed for heating hot pour crack sealants. Some means of agitation and monitoring of temperature are recommended. The range of safe heating temperature for the product is between 325-375° F. At no time should this product be heated to 425° F. This can degrade the polymers in Thermoflex and create a fire hazard. A direct fire melter can be used if these precautions are met. It also is suitable for use in an oil-jacketed double boiler. Because Spec+Plus contains no fillers, it is an excellent product for use through pumping type kettles.

- Limitations
Do not overheat material; Do not apply to wet or dirty cracks; Not recommended for cracks over 1" wide; Do not store in direct sunlight or where temperature exceeds 120° F
- Maintenance
Remove from equipment and tools with heat. Clean hands with waterless hand cleaner.
- Precaution
Extreme care must be taken with hot applied sealants; A long sleeved shirt, long pants, gloves and face protection must be worn; Severe burn hazard; Keep out of reach of children
- Technology
- Ready-to-Use Products
- Preparatory Work
Crack or joint must be properly prepared prior to installation of Thermoflex by means of routing and/or the use of a hot compressed air jet to remove all incompressibles and assure the sidewalls of crack are clean and dry.
