When cement mortar becomes dry and flaky, it is usually due to improper mixing of the mortar, excessive water evaporation during curing, or insufficient curing time. This can weaken the bond between the mortar and the materials it is adhering to, leading to potential failure or cracking. It is important to follow proper mixing and curing procedures to ensure a strong and durable bond.
