3M™ DI-NOC™ Stone Exterior Architectural Film - ST-442EXR

ST-442EXR
This ST-442EXR finish brings a dense black granite look animated by deep grey mottling and tight mineral speckle that scatters across the surface. The composition reads as polished volcanic rock with substantial visual weight. It suits exterior building facades, entrance columns, signage panels, and outdoor monument-style installations.

Stone Series
Stone by 3M offers the surface presence of cut slab in a flexible wrap, with patterns capturing veining, aggregate, and tonal depth across marble, granite, and slate looks. The collection conforms to substrate without the weight or labor of real stone. Designers select the series for projects that demand stone gravitas in a manageable installation format.

Exterior
The EXR designation marks 3M's reformulated exterior grade — a UV-stable chemistry engineered for vertical outdoor applications including facades, columns, signage, and door wraps. The series replaces the legacy EX line with improved colorfastness and an expected 7-to-16-year service life depending on exposure conditions. The film resists fading, moisture infiltration, and weather-driven color shift while delivering interior-grade visual fidelity outdoors.

3M™ DI-NOC™
3M™ DI-NOC™ architectural film opens up remodel options that traditional construction cannot match in speed or waste profile. The catalog runs deep with more than 900 patterns engineered for durability, stain resistance, and straightforward maintenance. Application surfaces include walls, columns, doors, cabinetry, and curved profiles, with 3M™ Comply™ Adhesive technology helping installers minimize bubbling and finish faster.
