After applying the first coat, when should the second coat of cement plaster be applied?

24 hours
48 hours
72 hours
One week later

The correct answer is: 48 hours

The second coat of cement plaster should be applied after a suitable curing period following the first coat. Applying it after 48 hours strikes a balance between allowing sufficient time for the first coat to cure and preventing delays in the overall finishing process. If the waiting time is too short, the first coat may not have set properly, leading to issues such as delamination or poor adhesion between the layers. Conversely, waiting too long could allow the first coat to dry out excessively, which could also compromise the bond when the second coat is applied. Overall, 48 hours serves as an effective timeframe to ensure that the first coat is adequately cured, making it optimal for the subsequent layer of plaster to adhere properly and ensuring a durable and resilient finish.
