Here a proprietary evaporation retarder is being applied to the surface of
the concrete. These products should be used during breaks in the finishing
process. As soon as finishing resumed, the film applied will be broken and
the protection from the product will be lost.
These products have traditionally been abused and treated as "finishing
aids." The products are largely water and can have the same adverse effect
on the concrete as adding any other form of water to the surface during
finishing.
