Tools & Materials
| Item | Purpose |
|---|---|
| PU stone panels | Choose textures like slate, brick, or cobblestone. |
| Construction adhesive | Heavy-duty adhesive (e.g., Liquid Nails). |
| Caulk & gun | Fill gaps between panels. |
| Utility knife | Cut panels to size. |
| Level & tape measure | Ensure straight alignment. |
| Sandpaper (120-grit) | Smooth rough edges after cutting. |
Step 1: Prepare the Surface
- Clean the wall: Remove dust, grease, or loose paint with soapy water.
- Repair damage: Fill cracks with spackle; sand smooth.
- Mark studs: Use a stud finder and mark vertical lines (for extra support).
Tip: PU panels stick best to dry, flat surfaces like drywall, plywood, or concrete.
Step 2: Plan the Layout
- Dry-fit panels: Arrange panels on the floor to test patterns.
- Start at the bottom: Begin installation from the lowest point to avoid misalignment.
- Stagger joints: Offset seams (like brickwork) for a natural look.
Step 3: Cut PU Panels
- Measure: Mark cutting lines with a pencil and ruler.
- Score and snap: Use a utility knife to score the panel, then bend to snap.
- Sand edges: Smooth rough cuts with sandpaper.
Safety: Wear gloves to protect hands from sharp edges.
Step 4: Apply Adhesive
- Back buttering: Spread adhesive on the panel’s back in zigzag lines.
- Wall application: For heavy panels, apply adhesive directly to the wall.
Pro Tip: Use adhesive compatible with your wall material (check the label).
Step 5: Install Panels
- Press firmly: Stick the panel to the wall, aligning with your layout marks.
- Check level: Use a level to ensure panels are straight.
- Spacer gaps: Leave 1/8-inch gaps between panels for caulking.
Note: Hold panels in place for 30 seconds to set the adhesive.
Step 6: Fill Gaps & Finish
- Caulk seams: Use paintable caulk to fill gaps between panels.
- Touch up paint: Match caulk and panels to your wall color.
- Clean excess: Wipe off stray adhesive with a damp cloth.
