Resin mosaic is a building decoration material which is becoming more and more popular nowadays. The main reason why resin mosaic will become popular is that stone mosaic can not be copied; glass mosaic has no texture; ceramic mosaic is easy to deform and discolor during firing, and can not guarantee its color and texture. The single shape of resin mosaic is irregular, concave and convex, which can show the pattern richly, especially in imitating leather, cloth, wallpaper, wood, metal and so on. It can almost achieve the effect of false and true.
