Chemthane 8190 joint sealer accommodates movement in concrete at expansion joints, the manufacturer affirms, as it ensures strength at the weakest spot
Chemthane 8190 joint sealer accommodates movement in concrete at expansion joints, the manufacturer affirms, as it ensures strength at the weakest spot of a concrete substrate where potential exists for constant damage. Providing a durable, flexible seal that will not become brittle and break out with movement, the product is suitable for repairing spalled joints, as well as filling random cracks and patching gouges, holes and surface defects. Chemthane 8190 is a 100 percent solids, two-part polyurea elastomer that cures to the touch in 60 seconds. It cures in applications ranging from freezing conditions to 130_F and will be ready for trimming flush within 20 minutes. Chemline
