The glue does not "tighten" (does not coagulate)
CAUSES
Similar to the above paragraph may be:
1. Weather conditions (eg low temperature, high humidity, etc.)
2. Too much water in the glue.
3. Incorrect Booster Ratio.
Technical characteristics and open application time vary depending on the type of adhesive even on adhesives of the same company. DO NOT use dissimilar types of glue waiting for you to have the same results in technical specifications and performance.
