What is limescale?

Limescale naturally builds up everywhere water flows, gradually damaging tapware and surfaces. Discover where limescale comes from and how to efficiently deal with it.

  • What is hard water? What is limescale? Running water naturally contains diluted minerals such as calcium carbonate and magnesium. How much of these minerals are available per gallon will determine the “hardness” of the water. Hard water contains calcium bicarbonate, which is a water soluble salt. Upon drying, water evaporates and carbon dioxide is expelled, leaving behind calcium carbonate i.e. limescale.
    image In France, for example, regions like Brittany and the Massif Central naturally have soft water. However, other regions, like the north of France and the Alps have very hard water.
    Scientifics measure water hardness in degrees: water Ask your local utility supplier about your home water degree.
    Wherever it runs, water gradually deposits some of these minerals. As they crystallize, they tend to form a white layer: that’s limescale.
    Hard water, with higher mineral concentration, is particularly prone to limescale build-up. However, limescale also occurs with soft water.
  • What does limescale do? You’ll first notice kitchen and bathroom tapware lose their shine, glass shower walls are less transparent, and tiles have a chalky surface. After a while, water runs less smoothly, as if taps were gradually blocked. All of these issues are related to limescale.
    Limescale starts as a cloud and progressively builds on white layers that end up creating actual hard-stone bits. The more you wait, the more difficult it is to remove.
  • Dealing with limescale: Expert products such as Viakal offer a quick and lasting solution to deal with limescale. First, it dissolves limescale and entirely erases its dulling effect, to deliver a remarkable shine. Second, a unique polymer pro-shine technology integrated in the formula prevents further build up and hard water deposits. It literally chases away drying water drops, thus reducing the chance of limescale deposits to form. It protects surfaces from further damage, keeping them clean and shiny longer.
