First of all, do not mix more grout than can be used within 30 minutes or less. Secondly, do not retemper mixed grout to restore workability. Do not add excessive amounts of water and do not apply to frozen substrates or at temperatures below 40 degrees. Also, avoid vibrating wet grout which can cause segregation and bleeding. Finally, do not add plasticizers, accelerators, retarders or additional cement.
