Lacquer is the ultimate glamorous finish for a wall. It is an expensive and often impractical treatment to do, as it shows any imperfections in sheetrock and plaster. But when it's done right, boy is it gorgeous!A shiny wall is such an unexpected touch in a room. The finish allows you to contrast with earthier textures like woods, or to play up the fancy pants factor with rich velvets and silks in your upholstery choices. When done in bluey tones, lacquered walls can also make a space feel like its surrounded by glistening water.
