Here is how to achieve a contractor-grade installation on your own.
You have purchased your materials from the Jinbao WPC Wall Panel Collection, and you are ready to transform your space. While WPC (Wood Plastic Composite) is famous for its ease of installation, the difference between a "good" job and a "perfect" job lies in the construction techniques.
Whether you are a professional contractor or a DIY enthusiast, this guide covers the technical nuances—from handling uneven walls to mastering seamless corners—that ensure your wall stands the test of time.
Success is 80% preparation and 20% execution. Do not skip these checks.
WPC materials can expand and contract slightly with temperature changes.
Technique: Unpack your panels and lay them flat in the room where they will be installed for at least 24 hours. This balances the material's temperature with the room, preventing post-installation warping.
WPC panels are somewhat flexible, but they will follow the contours of your wall.
The Test: Place a long spirit level against the wall. If gaps exceed 5mm, do not install directly.
The Fix: Install a wooden keel (grid) framework first to create a perfectly flat surface.
Gather these essentials:
Cutting: Miter saw (for clean cross-cuts) and Jigsaw (for outlets).
Fastening: Structural adhesive (Liquid Nails) and stainless steel clips.
Measuring: Laser level (preferred) or spirit level.
Follow this workflow for a seamless result.
The first panel dictates the alignment of the entire wall.
Technique: Start from the internal corner. Cut the "tongue" off the first panel so it fits flush against the corner wall. Use a laser level to ensure it is 100% plumb (vertical). If the corner isn't square, scribe the panel to fit.
For Flat Walls: Apply adhesive in an 'S' shape on the back. Press firmly.
For Keels/Studs: Use metal clips screwed into the groove lip.
Pro Tip: Always leave a 2mm expansion gap at the top and bottom of the panel (covered later by skirting boards or cornice) to allow the building to breathe.
Insert the tongue of the second panel into the groove of the first.
Technique: Use a rubber mallet and a scrap piece of wood (tapping block) to tap the panel gently into place. Never hit the panel directly with a hammer, as you will damage the locking profile.
The edges and cuts are where amateurs get stuck. Here is how to handle them.
Don't leave ugly gaps around power sockets.
Technique: Measure the distance from the last installed panel to the socket. Mark the cutout on the back of the WPC panel. Drill a pilot hole in each corner of your mark, then use a jigsaw to connect the dots.
Exposed edges ruin the aesthetic.
External Corners: Use a matching L-shaped corner trim from our Product List. Apply a thin bead of glue and tape it in place until dry.
End Caps: If the paneling stops mid-wall, use a U-channel or end-cap trim for a clean border.
Problem | Cause | Solution |
Panels won't lock | Debris in the groove or misaligned wall. | Clean the groove with a brush. Check if the previous panel is plumb. |
Bulging panels | Not enough expansion gap left. | Remove the skirting board and trim 2-3mm off the bottom/top. |
Visible seams | Panels not tapped in tight enough. | Use a tapping block and mallet to close the gap. |
Once installed, WPC is incredibly low maintenance.
Cleaning: Wipe down with a damp cloth and mild detergent.
Inspection: Check the silicone sealant around wet areas (like bathrooms) once a year to ensure it's still watertight.
Installing WPC Wall Panels is one of the most rewarding construction projects because the visual impact is immediate. By following these professional techniques—acclimatizing your boards, leveling your walls, and finishing your edges—you ensure a result that looks expensive and lasts for decades.

A: Ideally, yes. Wallpaper can peel over time, taking the adhesive (and your new panels) with it. For the strongest bond, install directly onto a clean, dry, and stable substrate.
A: Absolutely. Horizontal installation can make a narrow room feel wider. The installation technique is the same, just start from the bottom and work your way up.
A: Use a fine-tooth blade (60+ teeth) on your circular saw. If using a handsaw, cut with the decorative face up. If using a power saw, cut with the decorative face down to prevent chipping the surface.
A: If you used clips, simply unscrew the clip and remove the panel. If you used adhesive, you must act quickly before it cures. If the glue has set, you may need to cut the panel out and replace it.
