For Surface Shrinkage Cracks.
After applying Protec III: Original it maintains moisture in the concrete surface, which results in a full 30 day cure, and prevention of plastic shrinkage cracks.

For White Staining (Efflorescence).
By reacting with the alkali minerals in your concrete surface Protec III: Original prevents white efflorescence from coming out and staining your concrete, this also densifies your concrete surface.
