Venetian plaster is a classic tradition that lends nuanced color and shine to plain walls, often mimicking the aesthetic of stone or marble without necessitating that you splurge on such expensive materials. Venetian plaster is much more luxurious and versatile than most people give it credit for. If you love the old world aesthetic and elegant simplicity of hundred-year-old European homes, then Venetian plaster might be the perfect finish for your own custom home building project.
