Tadelakt plaster has been used in ancient kitchens to create a colorful and textured backsplash. This traditional Moroccan plastering technique involves applying multiple layers of lime-based plaster, which is then polished to create a smooth and shiny surface. Tadelakt plaster can be tinted with natural pigments, allowing for a wide range of colors to be used in the kitchen. The use of tadelakt plaster not only adds a vibrant and unique look to the kitchen but also provides a waterproof and durable surface.
