Why does Bluestone change color?

Have you ever encountered your bluestone pavers having a rusty orange look? Or perhaps these pavers start to darken? Do not worry! This is a natural occurrence for this type of stone.

One quality of bluestone is being water-resistant. These stones absorb moisture, and too much moisture causes discoloration. That is why it is recommended to apply a sealant days after installing it.

Some rocks, including bluestones, contain ferrous oxide minerals. Because of this, when bluestone is subjected to too much moisture, the pavers tend to develop a rusty orange color.

If these stones are not sealed, the moisture can enter from under the pavers or just above the surface.

With time, your bluestone pavers may change color. This usually happens because the paving stones have been worn out or seasoned.

In other situations, bluestone pavers darken. But don't fret too much! This is because of mold and mildew forming on your bluestones. All you have to do is to clean your pavers. Keep them clean and maintained, and they will look good as new.
