High-quality and exclusive materials are increasingly being used in gardens and terraces to create an individual atmosphere. The choice often falls on natural stones, which are a sought-after material for façades, terraces and staircases. If you want to enjoy the material for a long time, you should already inform yourself about cleaning possibilities and protective treatments when choosing the material.
From a technical point of view, the following happens:
Natural stones are permeated by capillaries and pores. In this system of cavities, the transport of impurities from the subsoil, the surface or dissolved substances inherent in the stone takes place. This also applies to granites or gneisses, which give a very robust impression. The diversity of natural stone is reflected not only in its appearance and texture but also in its strongly varying capillary absorbency, which causes its sensitivity to stains.
