3M™ DI-NOC™ Architectural Finishes Metallic Hairline is designed for finishing internal surfaces. It is characterized by a small, three-dimensional pattern perceptible to the touch. The laminate is non-transparent, so well hidden surfaces. It comes in colors from white, through neutral to brown (including copper). It is recommended to apply it on the smooth surfaces without scratches. It should be applied with delicate tools that will not damage the top layer of the film.
