NxTech’s NXT-1200 Mender Crack Repair System is a two-part, high penetration, fast setting,
polyurethane filler for repairing and re-building damaged and cracked concrete. This series
includes either the NXT-1291(Slow Cure) Part A or the NXT-1281(Fast Cure) Part A and the
NXT-1200 Part B components. The product is a 1:1 ratio, easy to mix system that is 98% solids
and VOC compliant. The NXT-1200 System can be used to set anchor bolts, repair damaged
control joints, fill spalling, and rebuild vertical curbing and steps. Sand or gravel (free of
moisture) can be added to extend the volume of the material and acts as filler for repairing
large spalls, holes and cracks. It has a fast cure time with excellent adhesion and its’ low
viscosity allows for fast turnaround of coating projects or as a standalone product.
