Caution: Never add extra water to a batch of colored concrete. Any differences in slump in successive batches will result in color variations in the concrete. Never use calcium chlorides or any accelerators.


Caution: Never fog the surface of the concrete with water; never wet the tools during use. The use of water will result in discoloration and may even damage the surface of the concrete.
