Get Your Discolored Sandstone Cleaned By Professionals
Don’t we all love the look of sandstones? A driveway or pathway built of sandstone changes the entire outlook of a property, giving it an aura of elegance. However, when these sandstones become discolored and its color changes to black or green or something which is far from natural, it mars the entire beauty. No amount of regular cleaning restores the beauty of these stones.
So, why do sandstone becomes such discolored in the first place? You need to understand that sandstone is not as hard as it looks. It is porous and allows accumulation of foreign materials within it. It is the perfect breeding ground of algae and moss. These microscopic growths within the sandstone causes it to become discolored and disfigured. But, that is not all that the algal growth does. They also disintegrate the stone from within and causes it to get damaged over time.
