The facade is your building’s visiting card, and it will make a bad impression if it is dirty or damaged. The building will also depreciate, because the damage will impair the building fabric. That’s why it is better to eliminate a facade’s "natural" enemies, such as water, UV rays and air pollution, from the outset. The best solution is to use a hydrophobic, though breathable coating. Everything hinges on the right plasters, primers and paintwork. Only coatings finely tuned to the respective substrate fend off harmful external influences and afford valuable building components lasting protection.
