| Wall condition | Inspect the surface for loose paint, peeling wallpaper, damaged drywall, stains, or signs of leaks. | The wall is dry, sound, and free of loose material that could interfere with installation. | Repair damaged areas, remove loose coverings, and identify and fix the source of any leak before covering the wall. |
| Wall flatness | Place a straightedge across several areas of the wall and look for pronounced high or low spots. | The surface is even enough for the strips to sit flat without rocking or bowing. | Correct significant unevenness or use suitable shims where needed; check that the finished strips will remain aligned. |
| Moisture | Use a moisture meter on exposed wood framing or the wall material where appropriate. Check suspicious stains and areas near plumbing or windows. | The wall is dry, with no active moisture source. For wood framing, follow the finish and adhesive instructions; readings below about 16% are commonly preferred for interior finish work. | Stop and investigate damp areas. Allow materials to dry, repair leaks, and recheck; readings near or above 19% in wood framing warrant further investigation before covering. |
| Stud locations | Locate studs with a stud finder and confirm by checking an edge, outlet location, or small test hole where safe. Mark each stud center from floor to ceiling. | Stud centers are identified clearly, and the wall framing is suitable for fastening the strips. | Recheck uncertain locations. Avoid relying on a stud finder alone where wiring, pipes, or unusual wall construction may affect readings. |
| Stud spacing | Measure from the center of one stud to the center of the next and record the spacing along the wall. | Studs are located at 16 inches on center where expected; verify actual spacing rather than assuming it is uniform. | Mark every stud that is present. Adjust strip layout or add suitable backing where needed so fasteners can reach solid framing. |
| Fastening plan | Compare strip thickness, fastener length, and wall layers with the installation instructions. Mark where each strip will cross a stud. | Fasteners can pass through the strip and wall finish and achieve adequate purchase in the framing. | Choose fasteners appropriate for the materials and load, and plan for solid backing at strip ends or other areas that cannot align with a stud. |
| Electrical and plumbing hazards | Check for outlets, switches, plumbing fixtures, and likely wire or pipe routes before drilling or nailing. | Fastener locations avoid concealed services, and required access to electrical boxes is maintained. | Use appropriate caution and detection methods; do not drive fasteners where concealed wiring or plumbing may be present. Keep boxes accessible and properly extended as required. |
