Mastering Wall Graphic Application: The Essential Prep for Perfect Results
When it comes to wall media applications, your initial process sets the tone for the final outcome. A successful install starts well before the first panel goes on the wall. By following these key steps—and adapting them to your workflow—you’ll be well on your way to a flawless finish.
1. Site Inspection
Thorough prep starts with understanding your surface and space:
• Tack Test: Always bring a sample to check adhesion on-site.
• Measure Accurately: Take multiple measurements across both height and width—walls are rarely perfectly straight.
• Room Orientation: If possible, get a floor plan. Knowing where entrances are in relation to the wall helps position overlaps where they’re least visible.
2. Design Considerations
Strategic design choices can simplify installation and elevate results:
• Smart Join Placement: Plan panel joins between graphics or lettering for easier alignment.
• Overlap Recommendations: Allow 15–20mm for both vertical and horizontal joins.
• Use the Design to Your Advantage: With textured images (e.g., brick walls), align joins with less visible areas like mortar lines.
• Directional Planning: Match artwork overlaps with installation direction—left to right, or right to left.
• Include Drop Maps: Print layout with clear tile/drop numbers and install direction.
• Bleed Margins: Allow 50mm top and bottom, and 50–100mm in width.
3. Printing & Manufacturing
Choosing the right printer and finishing approach is crucial:
• Printer Selection: Machines like the HP Latex with overcoat functions (e.g., for Arlon DPF 4200) help reduce install imperfections.
• Correct Profiles: Use the right ICC profiles.
• Laminate Choice: Satin or matte laminates are preferred to reduce glare and hide wall imperfections.
• Solvent Printing: Allow proper outgassing—loosely wound, ventilated, and separated layers.
• Cold Lamination: Use minimal feed tension; avoid heat assist.
• Roll Handling: Always roll print face-outward and avoid tighter rolls than factory cores.
• Label Everything: Clearly number drops and indicate top/bottom for installer ease.
4. Surface Preparation
A well-prepped surface ensures long-term adhesion:
• Paint Types Matter: Most modern walls use wash-and-wear paints with Teflon, which resists adhesion.
• Use Viponds Surface Prep: Semi-gloss/Satin Walls: Use for removable or permanent vinyl. Matte Walls: Use only permanent vinyl.
Application Steps:
• Lightly sand to smooth out imperfections and de-nib surfaces.
• Wipe with a damp cloth to remove dust; follow with a dry cloth.
• Apply two generous coats of Viponds. Touch-dry in 30 minutes, re-coat after 2 hours.
• Ideal temp: 15–25°C. Avoid below 10°C or above 30°C.
• Cure for a minimum of 24 hours before installation (longer if humidity is high).
• Before installing, wipe again with a damp cloth and then dry.
5. Installation Best Practices
For clean application and long-lasting results:
• Masking: Use painter’s tape or medium tack application tape on ceiling and corners to catch bleed instead of damaging painted walls during trimming.
• Consistent Start Point: Begin each vertical drop from the same point to maintain consistent stretch and alignment.
• Avoid Pulling Down: Let the graphic hang naturally. Stretching distorts joins and creates tension.
• Trim Smart: Use a sharp 9mm 45° blade for clean edges.
• Specialty Tools: Use tools like Yellotools WrapDragon or KeenCut rulers for precise corner cuts.
• Final Checks: Remove any tape and inspect edges and overlaps to ensure everything is sealed and flat.
