To prevent the cement from:
- Dehydration of cement, which prevents
- Cracking of cement, which avoids,
- Discoloration of cement
Additional note:
- Since GIC is a water based cement, it is sensitive to water so exposing the GIC is also unwise in the sense that it might get contaminated with water, hence over-hydrating the cement and affecting its physical properties
- Note that the varnish is applied during the initial phases of GIC setting reaction to allow it to set comfortably, which means right after placement and before polishing
- Also note that some authors say that the polishing burs or any instruments that will be used for instrumentation on GIC should be applied vaseline on their working ends
