SikaFlow 640
SikaFlow-640 is a grout accelerator for SikaFlow-648, SikaFlow-649, and SikaFlow-678. This 1 quart can (part 809778) is added when those epoxy grouts have to cure below 60 F. It speeds early strength so equipment can return to service when heating the exterior space is impractical. One quart is ordered for each full-size kit, and it does not improve grout workability in the cold.
