NCS stone care + brilliance
Precious stone floors deteriorate due to erosion or the usage of wrong cleaning agents. Spilling of certain substances, such as acidic fluids (vinegar, sparkling drinks...) or greasy and oily liquids may also result in enduring flaws.
An impregnation will protect the stone from absorbing dirt. It should be applied at least once a year (in highly frequented places) or every other year (private homes).
