Seamless Wall Panel Step-By-Step Installation Guide
1. Acclimate the Panels
Let your panels sit in the room for at least 4 hours before installation to adjust to ambient temperature. This prevents warping and ensures proper adhesion.
Note: Make sure to inspect them for damage that may have been caused during transport before installation as once you install the panels on a wall or ceiling, you will not be entitled to make any warranty claims.
2. Prepare the Wall
Start with a clean, dry and smooth surface. Patch any holes or imperfections with a filler. If the surface is glossy, lightly sand it with fine-grit sandpaper to create a better grip for the adhesive.
Note: Apply a primer to the wall before installing the panels. This step improves adhesion and long-term durability.
3. Plan your Layout
Lay out your panels on the floor or sketch a plan to determine your layout. Pay attention to:
- - Pattern direction
- - Panel alignment and cuts
Use a level and pencil to mark guidelines directly on the wall.
4. Cut the Panels
Measure and mark your panels as needed. Use a heavy-duty cutter to make clean and straight cuts. This step is crucial for tight, seamless joints.
5. Apply Adhesive
Apply the adhesive in a zigzag or dotted pattern, keeping about 1 inch from the edge. Also apply a small line of adhesive along the edges that will contact adjacent panels for a tight seam. Be careful not to over-apply. Excess adhesive can ooze out during installation.
6. Install the Seamless Panels
Gently press each panel against the wall, aligning it with your pencil marks. Hold it in place briefly to ensure proper bonding. Avoid pressing too hard, this could dent the foam. Use a damp cloth to wipe away any extra adhesive before it dries.
7. Seal the Seams (Optional)
If there are minor gaps between panels, apply a thin bead of acrylic filler. Let everything dry for at least 24 hours before painting.
8. Paint the Panels (Optional)
Use acrylic or latex paint designed for interior use. Apply two coats for best coverage. We recommend testing on a spare panel first.
Avoid spray paints or oil-based products that may damage the foam.
