Does colored concrete fade?

Cement Colors Inc state that the color can’t fade, but the concrete can. Left unprotected or weakened by a poor mix design or finishing job, the surface of concrete “dusts” and erodes slowly until fine aggregate and sand particles are exposed. This same process occurs in colored concrete.

How long does it take for colored concrete to cure?

In warm, sunny weather, concrete should be nearly its final color after about two weeks. In cooler, damp or overcast weather, the concrete will take at least a month or longer to reach its final color. After experiencing color variations a few times as a contractor myself, I did some research.

Why is my colored concrete turning white?

Should colored concrete be sealed?

Colored concrete will get good and hard just like normal concrete. However, all concrete benefits from being sealed against stains and water damage. So even though it’s not necessary, sealing your colored concrete will make it look good longer and will help prevent dusting of the surface.
