Whether on new constructions or renovation projects, a recurring façade issue is becoming increasingly common: a light-grey film on facing bricks. This alteration is not a temporary deposit such as cement haze or salt efflorescence, but the long-term consequence of a chemical process: brick greying, also known as gypsum formation on bricks. Brick greying does not only affect the aesthetic appearance of a building – it also significantly increases long-term façade maintenance needs.

In the world of sustainable construction, water-based hydrophobic treatments are increasingly becoming the standard. These modern technologies offer powerful, long-lasting protection for facades and roofs – without harmful solvents or emissions.

To finish a façade, you can opt to finish it with a cement-free clay mortar. While clay is a technique that has been used for hundreds of years to finish and protect exterior and interior walls, chipping is a more recent, more decorative technique.
