Heritage & Breathable Coatings in Hampstead

Pre-1919 buildings were constructed with flexible lime mortar and should only be decorated with breathable, vapour-permeable coatings. Standard modern acrylic and vinyl paints trap moisture within solid walls, leading to blown plaster, structural timber decay, and rapid paint failure. Our heritage coating specialists are trained in the application of traditional breathable systems: limewash (calcium hydroxide mixed with natural pigments) for internal lime plaster and external masonry; casein distemper and soft distemper for decorative internal ceilings and cornicing; and Keim Granital mineral silicate paint for exterior facades. Keim, developed in Bavaria in 1878, works through silicification — the liquid potassium silicate binder penetrates masonry and forms a permanent covalent chemical bond, turning the paint to stone. The result is a vapour-permeable finish with extraordinary UV resistance that can last decades without fading.
