There are lumps in the glue afterwards and stirring
CAUSES
1. We did not mix the mixture properly with the required water dosage (it is relatively tight). Refer to the instructions on the glue sack, fill in water, stir the mix with an electric stirrer and allow 10 minutes to mature before mixing again.
2. It is possible that the glue due to poor storage has "pull" moisture.
3. We have used a lot of water (add extra glue).
