Wall paneling is one of the highest-impact changes available for a weekend of work. It is also easy to do in a way that looks obviously added on.
Plan the layout before cutting anything
Measure the wall and divide it so the panels come out even and symmetrical. A layout with a full panel at one end and a narrow sliver at the other reads as an error even to people who cannot say why.
Work from the center outward, or balance the end pieces so both sides match. Draw it at full scale on the wall in pencil before you commit.
Address the height honestly
Panel height should relate to the room. A common approach places the top rail at about one third of the wall height, but the more important consideration is what it lines up with: window sills, door casings, the top of a backsplash, the back of a sofa. Aligning with an existing horizontal line is what makes it look intentional.
The details that sell it
- Deal with the existing baseboard. Either remove it and reinstall on top of the paneling, or make the paneling die into it cleanly. Paneling that stops awkwardly above an old baseboard is the giveaway.
- Handle outlets properly. Electrical boxes need to be extended forward to sit flush with the new surface. Box extenders exist for exactly this and cost very little.
- Scribe to the wall. Walls are not flat or plumb. Fitting pieces to the actual wall rather than assuming square is most of the work.
- Cap it properly. A top rail or a small ledge finishes the transition to the painted wall above. A raw panel edge never looks right.
Fastening
Locate studs and fasten into them where you can. Construction adhesive plus finish nails works well for the field. Set the nails slightly below the surface, fill, and sand before painting.
Finish before you think you need to
Prime and paint the panel material before installation, then touch up nail holes and joints afterward. Painting flat pieces on sawhorses is dramatically faster and gives a better result than painting into every inside corner on a wall.
Where it goes wrong
Uneven layout, ignoring the baseboard, and skipping caulk at the top edge where the panel meets the wall. That thin caulk line is what makes the whole thing read as one surface.
