Why does stamped concrete turn white?
Efflorescence is a chalky white salt residue that can occur with any product containing cement. As moisture migrates up to the surface of the concrete, it carries along with it calcium salts from within the concrete. When the salts reach the surface, they react with CO2 in the air and form insoluble calcium carbonate.
How do you fix cloudy stamped concrete?

What does xylene do to stamped concrete?
It is readily available at any home center, paint store, or hardware store. By applying a coat of straight xylene, one breaks down or re-melts the coat of sealer that is already on the surface.

Why did my pavers turned white?
The phenomenon of efflorescence occurs when water soluble salts migrate to the surface of the paver with the help of water (i.e., condensation, rain). Once the mixture of water reaches the surface, it mixes with the carbon dioxide in the air and creates a white haze/film that covers the pavers.
