See “Adhesion Compatibility with Application Surfaces” on page 3. Glossary of Terms Application Surface: The actual surface to which a Product is applied. This may be a bare application surface or a finish on an application surface, such as paint, varnish, or laminate. Porosity: The amount of void compared to solid material in an application surface. Product may appear to adhere well initially to some porous application surfaces, but adhesion decreases significantly over time. Apply an appropriate product to seal porous surfaces. Sealer: A coating applied to an application surface to seal a porous surface. Below are some terms that describe the surface’s tactile feel, which has a significant effect on Product choice, ease of application, and adhesion. A very smooth application surface will have the best Product adhesion and coverage. For rough application surfaces, consider using a Product with more visual design and/or embossed texture. • Very smooth: No surface variation, such as glass. Allows for the easiest Product application. • Fairly smooth: Little surface texture, such as painted wallboard. Allows for easy Product application and good adhesion, but texture may show through some Products. A Level 5 Gypsum Board Finish (ASTM C840) is an example of a “fairly smooth” surface. • Rough: Has obvious visual and tactile surface variations, such as concrete block, brick, textured wallpaper, etc. Product may not adhere well due to the adhesive not having full contact with the surface. In addition, the surface’s texture will show through almost all Products. See “Adhesion” on page 2 and “Surface and Work Area Preparation” on page 8 for instructions on rough application surfaces. * E-Series RC Recycled Content Film has a base film layer made with 80% post-consumer recycled polyester and a colored layer made with 20% scallop shell powder as a biobased filler. Figure 1. Examples of Film Contact on Smooth Surfaces 2 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes Non-compatible Application Surfaces • Brass, copper and other corrosion-susceptible metals • Non-sealed concrete and stone • Non-sealed drywall, including skim-coat • Other porous substrates Installation Tools and Supplies Adhesion Initial and Final Adhesion An adhesive­backed Product will have both initial and final adhesion. Adhesion will vary depending on the surface type and texture, installation conditions and techniques, and Product exposure conditions, any of which can prevent a Product from achieving a full bond to the application surface. • Initial adhesion is the bond needed to hold the Product in place during installation. 800 grams of adhesion is recommended when tested using a spring scale per the 3M Adhesion Test section. Good initial adhesion requires a substantial portion of the adhesive to be in contact with the application surface. • Final adhesion, or maximum bond, is achieved 24 to 48 hours after Product application. Good final adhesion requires a suitable application surface with an optimal surface, correct Product installation techniques, and Product exposure conditions within those specified for the Product. Adhesion Considerations • An adhesion promoter may aid in Product adhesion. See the “Adhesion Promoters” section below. • If Product is stretched during application, it may shrink later, which decreases adhesion. Using an adhesion promoter may minimize shrinkage. Adhesion Promoters Using an adhesion promoter can significantly increase a Product’s adhesion. When considering using an adhesion promoter users should understand the Product will be more difficult to reposition on the surface due to enhanced adhesion, and Product removal will be more difficult and may cause additional damage to the substrate. Using Adhesion Promoter • Use of an adhesion promoter is recommended at Product overlaps, ends, corners, edges, or around fixtures. It should also be used wherever the Product is stretched. • Adhesion promoters are often not needed on flat or high energy application surfaces, such as metal or glass. • Allow adhesion promoters to dry per manufacturer’s instructions. – Allow water-based adhesion promoters to dry at least one hour before Product installation. – Allow solvent-based adhesion promoters to dry at least 5 minutes before Product installation. • 3M™ Hand Applicator PA-1 (Blue or Gold) (optionally apply 3M™ PTFE Skived Film Tape 5480 or the loop side of 3M™ Hook and Loop Tape to reduce surface friction during application) • Razor blade knife with stainless steel replacement breakaway blades • An appropriate container for holding discarded cutting blades or tools • Liner cutting tool (i.e. Seam Buster tool) • Steel ruler with nick-free edges • Scotch™ Masking Tape • 3M™ Air Release Tool 391X • Measuring tape • Adhesion promoter and brush • Industrial heat gun capable of attaining and sustaining 100°F to 500°F (38°C to 260°C) or equivalent equipment • Clean, lint-free cloths • 70% isopropyl alcohol (IPA) solution • 3M™ Scotch-Brite™ Hand Pad • Sand paper • Soft-bristle brush 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3 3M™ DI-NOC™ Architectural Finishes Adhesion Promoter Properties The following table contains general properties of adhesion promoters and general application surface types where useful. Adhesion Compatibility with Application Surfaces The chemistry of paints has been changing over the years to drive down the level of volatile organic compounds (VOCs) due to both sustainability efforts and regulatory requirements. These new paint formulations have changed how the painted surface interacts with the adhesive on the Product, affecting its ability to adhere to the paint. Because paint formulations are protected trade secrets, it is difficult for film manufacturers to understand how adhesives interact with these paints. Products may perform well on one paint and poorly on another. However, by using the new 3M™ Enhanced Adhesion Cleaning Method and the 3M Adhesion Test, users can quickly and easily adhere almost any Product to nearly any paint or surface finish. The following table contains peel adhesion information for the Product peeled from various surfaces. A number of surfaces have acceptable adhesion without using any adhesion promoter. Examples of increased adhesion with adhesion promoters on certain surfaces are presented. Surfaces vary widely, so adhesion should be assessed on each application surface. Some surfaces are porous and must be sealed before applying film to prevent outgassing of the surface over time.

(300mm) per minute. WP-2000 undiluted for testing Acceptable adhesion Adhesion failure 1 Bubbles may appear under film due to outgassing if the plastic application surface is not fully cured before application. 2 If the Product is wrapped and overlapped around edges, use of an adhesion promoter is highly recommended due to additional stress from wrapping the Product. 3 The sealer was wiped with isopropyl alcohol to improve adhesion. Adhesion was tested after 15 minutes using a spring scale per the 3M Adhesion Test and passed at 800-1000 g/in. 3M Adhesion Test This test is designed to show the initial adhesion capability of a Product on a smooth indoor wall cleaned according to 3M’s recommendations. Product applied to contaminated walls, or walls exhibiting visible signs of peeling, lifting, bubbling, or dampness are likely to fail. The results of 3M Adhesion Tests will help determine if the wall is accurately prepared for 3M™ DI-NOC™ installation. Paint that has not fully cured may continue to outgas. Product applied over paint that has not fully cured may develop air bubbles over time. Before Doing the Test 1. Review and use the “Worksheet for Walls” on page 18. 2. Understand the types of wall surfaces and the variables that influence adhesion. 3. Test adhesion for three samples from each Product considered for each wall that will receive the Product and compare the results. i IMPORTANT NOTE 3M is NOT responsible for the results of the Product installation. Test Considerations • Perform the adhesion tests in an inconspicuous area of the same wall on which the actual job will occur. • Test the Product on each wall where the Product will be applied. While one wall may look the same as another in color and gloss, they may have been painted at different times and with different paint, affecting adhesion. Performing the test on a different wall/paint than that which will be used in the job will not provide the adhesion values and information necessary to make an accurate evaluation.

Such problems may result in poor adhesion as well as wall damage upon attempted removal of the Product. Adhesion Test Tools and Supplies • Spring scale – 0 to 1000 grams, part number 8003-MN – 0 to 2000 grams, part number 8004-MA • Isopropyl alcohol • Lint free cloths • 3M™ Rivet Brush RBA-1 • Copy or cut out the “3M Measured Reference Guide for Adhesion” on page 19. This will be used during the test to help you gage how fast to pull the Product strip. • Hole punch • Strips of each Product to be tested Prepare the Product Test Strips 1. Cut three, 1 in. by 10 in. (2.5 cm by 25 cm) strips of each Product to be tested for each wall to be tested. 2. Note the Product name or number on each test strip and on the Worksheet for Walls. 3. Remove about 2 in. (5 cm) of liner from each strip and fold the exposed adhesive back on to itself to make a tab. 4. Punch a hole in the tab. Adhesion Test Procedure 1. Clean the area of the wall you will test using the 3M™ Enhanced Adhesion Cleaning Method. 2. Use your thumb to initially adhere the Product strips (punched hole at the top) to the cleaned wall. i IMPORTANT NOTE Test THREE strips of each Product being evaluated on the same wall. After all three strips are tested, compare the results. 3. In a circular motion with firm pressure, move the RBA-1 rivet brush up and down the applied strips. Go over each strip three times to firmly adhere it to the wall. See Figure 3. 4. Tape the Measured Reference Guide Rule on the wall next to the Product strip you are testing. See Figure 4. 5. Wait 15 minutes to allow adhesion to build. 6. Zero out the scale.as shown in Figure 5. Figure 2. Preparing the test strips Figure 3. Adhering Product Strips Figure 4. Adhesion Test Figure 5. Zeroing the Scale 6 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes 7. Slide the scale’s S hook through the punched hole in the Product strip. 8. Hold the scale in your palm, keeping it as straight as possible but without any portion of the scale or your hand contacting the wall during the test. 9. Pull the scale downward at a steady rate of about 1 in. (2.5 cm) in 5 seconds, using the Measured Reference Guide lines as a guide. Once you have started pulling, DO NOT STOP until the Product strip is fully released from the wall. i IMPORTANT NOTE The Measured Reference Guide in Figure 5 is included at the end of this guide. 10. As you pull down on the scale: a. Observe the release characteristics of the Product and compare them to “3M™ DI-NOC Adhesion Test Recommendations” on page 6. b. Note and record the value in grams/in. that registers on the scale on the “Worksheet for Walls” on page 18. 11. Repeat Steps 2 to 10 for each test strips. Average the three results together. Test Evaluation – Smooth Walls Only 1. Averaging test results If two or three out of three strips of the same Product perform the same way, use those characteristics to judge the suitability of that particular Product for that wall. 2. Use the table below to interpret scale values. 3M™ DI-NOC Adhesion Test Recommendations • Unsatisfactory test results occur when: a. The test strip removes unevenly. • Inconsistent or low adhesion values due to high and low spots in the surface texture which cause the adhesive to not make full contact with the wall surface. • Cold wall and air temperatures which don’t allow the adhesive to flow or make full contact. b. The test strip pulls paint off wall. • If any paint is pulled off with the test strip, the paint is not sufficiently bonded to the wall and the Product should not be applied until the problem is corrected, a new paint is fully cured, and the “3M Adhesion Test” on page 4 is performed again with satisfactory results. Scale Value Adhesion Characteristics Recommendation Less than 800 grams/in. Removes very easily; little or no resistance Unacceptable adhesion; additional cleaning may be necessary 800 to 1000 grams/in. Smooth, consistent release; no jerkiness but more difficult to release Acceptable adhesion; may be removable with heat/chemicals; removal may cause wall damage Greater than 1000 grams/in. Smooth consistent release; no jerkiness, but substantial resistance to releasing Excellent adhesion; removal will cause damage 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 7 3M™ DI-NOC™ Architectural Finishes 3M™ Enhanced Adhesion Cleaning Method Using the 3M™ Enhanced Adhesion Cleaning Method ensures that the application surface is ready to receive and hold the Product. The installer must evaluate each application surface to determine cleaning requirements prior to Product installation. ! CAUTION For your safety, always wear protective eye wear and disposable gloves when cleaning application surfaces. 1. Ensure that any needed repairs to the application surface are completed prior to performing the 3M Enhanced Adhesion Cleaning Method. 2. Clean stubborn grease and grime using an appropriate, commercially available cleaning product. 3. Prepare a cleaning solution with a 70% isopropyl alcohol/30% water cleaning solution in a spray bottle. 4. Soak a clean, lint-free cloth with the IPA cleaning solution until it is dripping wet. See Figure 6. 5. Clean the entire application surface with overlapping strokes. Some paint particles may migrate onto the cloth. See Figure 7. i IMPORTANT NOTE Change cleaning cloths often to avoid redepositing contaminants on another part of the application surface. Soak each new cloth with the IPA cleaning solution. 6. Thoroughly soak another clean, lint-free cloth with the IPA cleaning solution and wash the application surface again. 7. The alcohol in the cleaning solution will lower the surface temperature of the application surface as much as 10°F (5.6°C), a noticeable difference. When the alcohol has completely flashed off, which takes about 10 minutes, the application surface will return to its normal temperature. Installers can use an IR gun (see Figure 8) to accurately measure the temperature before cleaning and immediately after cleaning, or simply touch the back of their hand to the cleaned area. When it no longer feels cool, it is dry and installers can proceed with the adhesion test, or with the Product installation. Estimated Time for Cleaning About 30 minutes is required to clean a 125 sq. ft. (11.6 square meters) area, which is approximately an 8 ft. by 16 ft. (2.4 m by 4.9 m) wall. Keep this in mind as you estimate your next job. Before cleaning After cleaning Figure 6. Soaking a Lint Free Cloth Figure 7. Removing Paint Particles Figure 8. Testing Wall Temperature 8 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes Surface and Work Area Preparation Use the following steps to prepare the application surface for Product application. An experienced installer’s techniques may vary. Inspect Application Surfaces Before installation, contact the property manager or the general contractor of the installation site to ensure that the application surface is ready for installation. i IMPORTANT NOTE Before covering application surfaces susceptible to swelling, such as wooden doors, wood-core doors, or gypsum board, ensure that the environmental conditions, such as temperature and humidity, are stable. Wide changes in humidity or temperature can affect the application surface, which may cause wrinkles or bubbles in the applied Product. i IMPORTANT NOTE It is critical that the paint, sealer and/or primer coatings be allowed to fully cure for the entire time period stated by the manufacturer. Repair Damaged Application Surfaces Repair any damage such as holes, loose wallboard joints, and any chipped or peeling material. 1. Fill any holes or gouges with Bondo® or non-water-based filler. Ensure that all filler is fully cured before proceeding. 2. For exterior surfaces, use a soft bristle brush to remove all loose particles, dust, sand, and gravel. 3. Sand the application surface. 4. Clean the application surface with IPA. 5. If the surface is porous, seal the application surface with a minimum of two coats of a primer or sealer. Follow the manufacturer’s recommendations for surface preparation. Allow the sealer or primer to fully cure before installing the Product. Clean the Application Surface Wipe down the application surface with a lint-free cloth and a 70% IPA/30% water cleaning solution, or use the “3M™ Enhanced Adhesion Cleaning Method” on page 7 if needed. For 3M™ DI-NOC™ EX Series Application Surfaces 3M™ DI-NOC™ EX Series for exteriors can be applied to the following vertical application surfaces: • Aluminum – Anodized aluminum – Colored aluminum – Painted aluminum – Aluminum composite panel • Galvanized steel • Painted steel Textured Exterior Surfaces Some exterior surfaces are highly dimensional and the adhesive may not have enough contact area to adhere properly to the surface. Contact 3M Commercial Solutions Technical Service with any questions about surface suitability. Exterior Application Surface Conditions Exterior application surfaces must not be loose, crumbling, contaminated, wet, or damp. The Product can be applied at temperatures as low as 54°F (12°C) on days when the temperature is expected to rise to at least 70°F (21°C). Heat helps the adhesive bond to the application surface; therefore, the warmer the temperature, the better the bond. 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 9 3M™ DI-NOC™ Architectural Finishes i IMPORTANT NOTE Do NOT apply the Product late in the day when the surface temperature is likely to drop. Installation Recommended application temperature: 54ºF to 100ºF (12ºC to 38ºC) These are the general Product application steps. An experienced installer’s techniques may vary. 1. Measure the application surface to be covered. 2. Cut the Product to size with a minimum 1/2 in. (1.3 cm) extra on all sides for trimming. 3. Put a set line in the liner 6 to 8 in. (15.2 to 20.3 cm) from the top. 4. Align the Product with the application surface and set the set line. 5. Pull out the liner approximately 8 in. (20.3 cm). 6. Starting in the center, use the squeegee to adhere the Product to the application surface using overlapping strokes. Repeat Steps 5 and 6 until the panel is completely applied. 7. Re-squeegee the entire panel for ultimate adhesion. Create a Double Cut Seam This technique is NOT recommended for 3D or curved surfaces,. A standard overlap seam is recommended for those surfaces instead. i IMPORTANT NOTE If the same Product will be used on each side of the double cut, be sure to use Product from the same roll or lot. 1. Ensure that Product design and/or “grain” of an embossed pattern always runs in the same direction or the application may have obvious shifts in color, gloss and/or design. i IMPORTANT NOTE Do not use double cut seaming with Products that have a designation in the 3M™ DI-NOC™ Architectural Finishes Product Catalog. 2. On the Product side where the seam will be, leave 1 in. (2.5 cm) of Product liner on the side of Panel A. See Figure 9. 3. Apply Panel A. 4. Apply Panel B overlapping Panel A by 1 in. (2.5 cm). 5. Remove the Panel B liner to adhere to panel A. The transition should be flat against application surface with no air pocket underneath. 6. Use a straight edge to cut through the overlap’s center. 7. Remove the excess Product and then the Product liner. 8. Starting in the center of the seam, use a fingernail or appropriate tool to bring the two edges of the seam together and tight to the wall. There should be no overlap of the edges at this point. Complete a 1 in. (2.5 cm) section of the seam before proceeding to the next step. 9. Starting in the middle of the 1 in. (2.5 cm) section, firmly squeegee the seam together with a rocking motion. Work the squeegee along the seam, keeping it tight to the film. For 3M™ DI-NOC™ WH-111 and PWF-500 Seams Seams in 3M™ DI-NOC™ Whiteboard Films WH-111 and PWF-500 can accumulate marker residue. When creating a double-cut seam, make all seams as tight as possible. When creating an overlap seam, use 3M™ Tape Primer 94 adhesion promoter under the overlap, which should be 1/2 to 1 in. (1.3 to 2.5 cm). Horizontal application at eye level is preferred, so as to allow continuous writing and erasing along the length of the whiteboard area. See the DI-NOC™ WH-111 Tech Data Sheet and the DI-NOC™ PWF-500 Tech Data Sheet. A Panel B Cut through both layers of Product. Overlap Panel Figure 9. Creating a double cut seam 10 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes Create an Overlap Seam i IMPORTANT NOTE Use Product from the same roll or lot on each side of the seam. For 3M™ DI-NOC™ EX Series Seams 3M™ DI-NOC™ EX Series for exteriors must have an overlap seam of at least 0.6 in. (15 mm). Apply with 3M™ Tape Primer 94 at the overlap. Overlap panels in the shortest direction, where possible. Apply the lower panel first, then apply the upper panel after sanding and priming the edge of the lower panel. This allows water to shed away from the seam. Multiple layers of overlapped film can cause edge lifting problems in high winds. Make sure there are no more than three layers of film at any overlapped seam intersection. See Figure 11. Substrate Masking tape For overlap (15 mm) Abrade the surface with #180 sand @1@5B<51>?ɢ sanding residue with 70/30 isopropyl alcohol solution. Overlap (15 mm) Primer Abrade the surface Figure 10. Creating an overlap seam Figure 11. Stagger seams on overlapped panels 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 11 3M™ DI-NOC™ Architectural Finishes Trimming After application, re­squeegee all Product edges to help ensure good edge adhesion before trimming. See Figure 12. Outside corners should be cut at a 45 degree angle. Inside corners should have an overlap of 1/8 in. (3.2 mm). For 3M™ DI-NOC™ EX Series Trimming: Inside corners should have a double-cut seam. Compound Curved Surfaces i IMPORTANT NOTE Use of 3M™ DI-NOC™ products on compound curved surfaces is strictly on a user test-and-approve basis. Using Heat to Conform Product Around Three Dimensional Surfaces Installers can improve many Products’ conformability by heating the surface of the Product until it is pliable enough to form around a three dimensional surface. ! CAUTION Overheating can damage the Product. Practice this technique on a test piece before attempting it on finished Product. 1. Ensure that you have enough Product to wrap around the edges to the surface’s bottom. Allow a minimum of 3 in. (7.6 cm) around the entire panel. 2. Apply adhesion promoter to the edges, starting about 1/2 in. (1.2 cm) from where the shape changes (see Reference X in Figure 13) and extending to the back side of the surface for at least 1/2 in. (1.2 cm) (see Reference Y in Figure 13). 3. Allow the adhesion promoter to dry to improve adhesion and minimize shrinkage.. 4. Apply the Product to the flat surface before conforming the corners and then along the straight edges in this sequence: A, then B, C and D, then E and F, etc. See Figure 14. 5. Neatly trim excess Product on the surface’s back side. i IMPORTANT NOTE For products identified in the 3M™ DI-NOC™ Architectural Finishes Product Catalog with the following symbols: Do NOT use on 3D Compound Curved Surfaces. Film will not conform around compound curves. Use caution when applying to 3D compound curved surfaces to prevent damage to product. Film may distort or not conform around compound curves. For DI-NOC EX Series on Compound Curved Surfaces: Compound curved surfaces are NOT recommended. Stretching the film can adversely affect Product performance including outdoor durability. Figure 12. Re-squeegee to ensure good adhesion. Figure 13. Apply adhesion promoter between X and Y. Figure 14. Apply the product on the corner. 12 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes 3M™ DI-NOC™ EX Series Edge Sealing The edges of 3M™ DI-NOC™ EX Series films should not be covered by sealing material except when absolutely necessary. Certain exterior applications of 3M™ DI-NOC™ EX Series films may require an edge sealer by the installer. When necessary, the film edge should be covered 1 to 2 mm maximum by the sealer. ! CAUTION Application to exterior glass surfaces is NOT warranted due to the risk of glass breakage caused by thermal expansion. i IMPORTANT NOTE Adhesion to exterior glass is NOT warranted, but caulking the entire edge of the installed film may help prevent water penetration. Application to exterior glass is to be done strictly on a user test-and-approve basis. Additional Recommendations by Product Series 3M™ DI-NOC™ EX Series Exterior Architectural Finishes Consider the following points when applying 3M™ DI-NOC™ EX Series Architectural Finishes. 1. 3M™ DI-NOC™ EX Series is designed for installation on exterior building elements. 2. Although the product is highly durable when used outdoors, the expected performance life will be reduced when used on non-vertical surfaces. See warranty in 3M™ DI-NOC™ EX Technical Data Sheet. 3. Aluminum, galvanized steel, or painted steel are the preferred substrates for DI-NOC EX Series for maximum expected performance life. 4. In low temperature environments, the product can whiten at creases, tears, and folded corners. Apply at recommended exterior air and surface temperatures between 54-100F (12-38C). 5. Handle with care during application to avoid creases and tears if the film is excessively bent. The product creases and tears more easily than standard DI-NOC Series. Applying and repositioning the product requires careful handling. 6. DI-NOC EX series is not as conformable as standard DI-NOC. Do NOT use on compound curved (3D) surfaces or deep channels. Avoid stretching the product during application due to low conformability. If the product is stretched it may be distorted. Accurately determine the starting point for the application of the product so there will be no need for adjustments. 7. DI-NOC EX Series is more difficult to cut than standard DI-NOC Series. Cut the product through to the adhesive with a sharp tool to avoid unexpected tearing or rough edges. 8. Seams require a ½ in. (13 mm) overlap joint. When making an overlap joint, install masking tape ½ in. (13 mm) in from the edge of the DI-NOC. Lightly sand the exposed ½ in. (13 mm) section of DI-NOC up to the masking tape until it is smooth. Clean the area with a microfiber or soft cloth and 70/30 Isopropyl alcohol/water solution. Apply 3M™ Tape Primer 94 in the overlap area, remove the masking tape and install the next sheet of DI-NOC with a ½ in. (13 mm) overlap. 9. The DI-NOC EX film edge should not be covered by sealing material except when absolutely necessary. 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 13 3M™ DI-NOC™ Architectural Finishes 3M™ DI-NOC™ MT Series Matte Architectural Finishes Consider the following points when applying 3M™ DI-NOC™ MT Series Architectural Finishes: 1. 3M™ DI-NOC™ MT Series utilizes a new state of the art matte surface texture. The matte surface of the film has less scratch and stain resistance compared to other DI-NOC series. Avoid applications in high traffic areas and impact with hard objects. Customers should test and approve the installation location. 2. Apply in a dust-free environment to avoid dust particles scratching the surface during installation. 3. Wrap the application squeegee in a clean, soft cloth to avoid scratching the surface of the film, especially on inside corners or butt joints. Alternately, use 3M™ Teflon Tape 5480 on the edge of the squeegee. Be careful to avoid making marks during application, especially VM-MT Series and dark colors of PS-MT and SU-MT Series, as these marks may be especially noticeable. Pressure from squeezing during installation may leave marks resembling white indentations which may recover with time. Wipe with a damp microfiber or soft cloth to shorten the recovery time. Deep indentations and scratches may not recover. 4. Handle with care during application to avoid creases if the film is excessively bent. Applying and repositioning the product requires careful handling. 5. DI-NOC MT Series may be applied to shallow complex curved (3D) surfaces with caution to avoid excessive heating and over stretching, except VM-MT Series is NOT recommended for 3D applications. Excessive heating and stretching may cause discoloration and/or damage to the matte surface. If cold wrapping around sharp outside corners causes whitening of the film, warming with a heat gun will make this less noticeable. Customers should test and approve 3D installations. 6. Cut edges may become noticeably white for dark colored patterns. Warming with a heat gun will make this less noticeable. 7. When making an overlap joint, install masking tape ½ in. (13 mm) in from the edge of the DI-NOC. Lightly sand the exposed ½ in. (13 mm) section of DI-NOC up to the masking tape until it is smooth. Clean the area with a microfiber or soft cloth and 70/30 Isopropyl alcohol/water solution. Apply 3M™ Tape Primer 94 in the overlap area, remove the masking tape and install the next sheet of DI-NOC with a ½ in. (13 mm) overlap. 8. Do NOT pierce the film to release air bubbles which may show white marks. 9. To remove oil stains, wipe with a microfiber or soft cloth dipped in 70/30 isopropyl alcohol solution. Dark colors may have a white stain after cleaning with this method.

Always handle the Product with care. 2. The Product edges may be sharp; use caution when handling. 3. Avoid scratching or denting the surface during installation as this may affect writing performance. 4. Before setting the adhesive to the application surface: a. Ensure proper alignment by using a guideline. Allow additional material for trimming as necessary. b. Ensure that the entire surface of the film is flat against the application surface and the ends of the film do not sag. 5. Stretching or attempting to reposition the Product during application may deform, buckle, or ripple the Product. 6. Wrinkles created during application cannot be removed with heat due to polyester construction. 7. Seams tend to accumulate ink from the markers. Make seams as tight as possible. 8. Horizontal installation at eye level is preferred, to allow continuous writing and erasing along the length of the whiteboard area. 9. If additional sections are installed, seams should be overlapped 1/2 to 1 in. (1.3 to 2.5 cm). Use Primer 94 adhesion promoter under the overlap. 10. If installed on drywall (or painted drywall), follow the Drywall Preparation & Installation Guidelines, 3M DI-NOC Surface Prep Guide. 14 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes 3M™ DI-NOC™ E-Series RC Recycled Content* Film Consider the following points when applying 3M™ DI-NOC™ Architectural Finishes E-Series RC Recycled Content* Film: 1. 3M™ DI-NOC™ Architectural Finishes E-Series RC Recycled Content* Film products utilize a new state of the art matte surface texture. The matte surface of the film has less scratch and stain resistance compared to other DI-NOC series. Avoid applications in high traffic areas and impact with hard objects. Customers should test and approve the installation location. 2. Apply in a dust-free environment to avoid dust particles scratching the surface during installation. 3. Wrap the application squeegee in a clean, soft cloth to avoid scratching the surface of the film, especially on inside corners or butt joints. Be careful to avoid making marks during application, especially with dark colors, as these marks may be especially noticeable. Deep indentations and scratches may not recover. 4. Handle with care during application to avoid creases that may occur when the film is excessively bent. Applying and repositioning the product requires careful handling. 5. With an approximate thickness of 5 mils (127 microns), these films are the thinnest products in the 3M™ DI-NOC™ Architectural Finishes line. Because the product is thin, it can easily tear and/or wrinkle. 6. This product is designed for smooth substrates such as metal or laminate. Apply to smooth substrates so the surface texture does not show through the film. 7. This product CANNOT be applied to 3D complex surfaces because it is not elastic and does not absorb wrinkles. Cuts in the film are prone to tearing, and wrinkles do NOT recover when heated. 8. When aligning, the film may unintentionally stick to the substrate, so conduct all work with care. 9. This product is for indoor use only. Do NOT use the product outdoors, in hot and humid conditions, or on expanding and contracting substrates. 10. Cut edges may become noticeably white for dark colored patterns. Warming the edges with a heat gun will make this less noticeable. 11. Do NOT make double-cut seams. The film may lift at double-cut seams over time. 12. Make overlap seams. Install masking tape with the outer edge 1/2 in. (1.3 cm) in from the edge of the film. Either lightly sand the exposed 1/2 in. (1.3 cm) section of the film up to the masking tape until it is smooth and clean the overlap film area with a microfiber or soft cloth and isopropyl alcohol and 30% water solution. Or apply 3M™ Tape Primer 94 in the overlap area. Then remove the masking tape and install the next sheet of film with a 1/2 in. (1.3 cm) overlap. 13. Small scratches or stains may be reduced by wiping with a clean, soft dry cloth. If scratches or stains can not be reduced by dry wiping, wipe with water and a clean, soft cloth. Do NOT use hard cloths or organic solvents as they may damage the film surface. 14. Stains may be noticeable on light colored products. To remove oil stains, wipe with a microfiber or soft cloth dipped in a 70% isopropyl alcohol and 30% water solution. Dark colors may have a white stain after cleaning with this method. Do NOT put solution directly on the film surface. 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 15 3M™ DI-NOC™ Architectural Finishes Cleaning and Maintenance Regular cleaning helps maintain the appearance of the finish. Use mild detergent, water, and a soft cloth or sponge without abrasives. For difficult stains, spot clean with a solution of 70% isopropyl alcohol (IPA) and 30% water and a soft cloth. Avoid using strong solvents or detergents that are either highly alkaline (pH>11) or highly acidic (pH<3). Do NOT use ammonia, chlorine, strong organic­based cleaning products, polishing or cleaning compounds, hard-bristle brushes, or electric polishing equipment. Use only clean, nick­free tools and wipe gently. For DI-NOC EX Series Power Washing Films Power-washing, or pressure-washing, may be used. However, aggressive washing can damage the Product. Excessive pressure during power-washing can damage the Product, by forcing water underneath the surface. Water lowers the adhesion force of the Product to the substrate, allowing the graphic to list or curl. These problems are further worsened by high winds, which can remove the Product from the substrate. Avoid pressure-washing perforated films applied without edge-sealing tape. To avoid edge-lifting, or other damage to the Products, follow these important steps: • Use a spry nozzle with a 40°-wide (minimum) spray pattern • Ensure the spray nozzle includes a nozzle protector (or tip guard) • Use a maximum pressure of 1200 psi (80 bar) • If the system is heated, limit the water temperature to 140°F (60°C) or less • Hold the nozzle at least 12 in. (30 cm) away from, and perpendicular to, the Product, or a minimum of 39 in. (1 m) away from the Product at spray angles of 30° or greater. • Do NOT direct the water stream between 0° and 60° from the Product surface. Removal Although Products may be removed, application techniques and adhesion promoters increase adhesion, so clean removal without substantial damage is unlikely. The following removal technique may be attempted, but effort levels and results will vary. 1. Cut the product into 4 in. (10.2 cm) wide segments. taking care to avoid damaging the substrate. 2. Optionally, use a heat gun set to 150°F to 200°F (66°C to 93°C) to soften Product adhesive. 3. Immediately pull the heated section of Product down at about a 180 degree angle. 4. Repeat Steps 2 and 3 with subsequent pieces of the Product. Problem Solution Dust and Grit Wipe with a soft, damp cloth. Soiled (but not gritty) Use water and a soft cloth. Heavily Soiled Clean first using a solution of mild liquid detergent and water, then use clear water. Wipe gently with a soft cloth. Difficult Stains Spot clean with a solution of 70% IPA and 30% water. Type of Surface Damage Cause of Surface Damage Method to Reduce Visibility Mar Dragging an item (such as a colored briefcase) across the film, leaving a deposit of color on the surface. Rub with a soft cloth and warm soapy water to remove the mar. Indentation Pressing into the film surface without breaking the surface, such as pressure from a chair. Carefully heat the indentation with a heat gun, which allows the film surface to rebound and reduce the indentation’s visibility. Scratch Breaking the surface layer of film leaving a slightly jagged whitish mark on the surface, such as by dragging a sharp rivet from a purse. Rub with a surface restorer such as 3M™ Marine Vinyl Cleaner & Restorer to reduce the visibility of scratches. Gouge Breaking through the entire film, such as from a severe impact from sharp chairs or carts. Repair the film by cutting out the damaged film and replacing it with the same pattern of film, or remove and replace the entire film panel. 16 3M™ DI-NOC™ Architectural Finishes Installation Guide – Revision K, March 2024 3M™ DI-NOC™ Architectural Finishes Troubleshooting Every effort should be made to ensure that walls are in good condition before applying the Product. This generally reduces installation time while improving the Product’s appearance and removal characteristics. • Review all troubleshooting options before deciding on a course of action. • Every wall paint must be fully cured for the full amount of time recommended by the paint manufacturer. • Follow the 3M Adhesion Test for every Product you intend to use and on each different wall included in the installation. • Every installation wall must be cleaned with the 3M™ Enhanced Adhesion Cleaning Method before doing the 3M Adhesion Test and before doing the full installation. Health and Safety ! CAUTION When handling any chemical products, read the manufacturers’ container labels and the Safety Data Sheets (SDS) for important health, safety and environmental information. To obtain SDS sheets for 3M products go to 3M.com/SDS, or by mail or in case of an emergency, call 1-800-364-3577 or 1-651-737-6501. When using any equipment, always follow the manufacturers’ instructions for safe operation. ! WARNING To reduce the risks of personal injury and/or property damage associated with glass breakage: A glass surface covered by a film with areas of high opacity or dark-colored ink will absorb more heat than other glass surfaces when exposed to sunlight. Heat absorption can create thermal expansion that could result in glass breakage or cracking. Do not use a film with areas of high opacity or dark-colored ink on glass surfaces with significant exposure to sunlight. Problem What To Look For Recommended Solutions Installation Problems – Smooth Walls The Product does not adhere well or falls off wall. The Product was not tested on the wall prior to installation. Always perform the 3M Adhesion Test for each Product and on each application surface before committing to the complete installation. Low VOC paint was used on the wall. Wall repairs were not properly sealed, primed, painted, or cured. Walls were not cleaned with a solution of 70% isopropyl alcohol and 30% water. Always follow the 3M™ Enhanced Adhesion Cleaning Method in this guide to increase adhesion. The texture of the application surface is not well suited to the Product being used. • Some textured paint additives create too much texture for Products that are intended for smooth walls. • A wall with too little texture may prevent proper air bleed during installation, trapping air under the film. In this case, use the 3M™ Air Release Tool 391X to make a small hole in the film to allow the air to escape. Resqueegee as necessary. The temperature of the application surface was too low. Refer to the “Installation” section on page 9 for the proper installation temperature range. Post-Installation Problems – All Walls Edges of the Product are lifting from application surface. Poor installation technique, or wrong tools Review this bulletin and ensure you are using the right Product, tools, and techniques for the application surface. Lots of practice is critical for consistent success. A large portion of the Product lifts or falls off. Poor initial bond of paint to wall Perform the 3M Adhesion Test. Perform the 3M™ Enhanced Adhesion Cleaning Method if the test results are less than 800 grams. Wall not properly cleaned Follow the procedure “Surface and Work Area Preparation” on page 8.
