PH-01Plan the room and buy materialsDecide the style and height of the dado rail (traditionally around a third of the way up the wall) and sketch where the panelling will run, avoiding narrow strips in corners. Follow 'How to tell what your wall is made of' to check whether you have masonry, stud, or dot-and-dab plasterboard, since this decides your fixings later on. Buy all timber, mouldings, adhesive, screws, and filler before you start so the job doesn't stall partway through. Budget roughly £400 to £900 for materials and an electrician, spread across two weekends plus a weekday for any electrical work.

PH-02Mark up the wall and check for hazardsFollow 'Using a detector before you drill' to scan the full height of every wall where the rail, panelling, and fixings will go, paying close attention around existing sockets, switches, and skirting. Mark the level line for the dado rail height all the way round the room, and mark stud or fixing points in pencil. Even with a detector, assume a cable or pipe could still be hidden, and treat any socket or switch area with extra care. Note now which sockets or switches fall inside the panelled zone, so you can sort them before fitting starts.

KNOW THE RULES

Always check for hidden cables and pipes with a detector before drilling or fixing into any wall, and still expect something to be there even after checking.

PH-03Get an electrician in for sockets and switches in the panelled areaAny socket, switch, or light fitting that sits inside the panelled zone needs a registered electrician to extend the cable and bring the faceplate forward so it sits flush once the panelling is on. This is work on an existing circuit, so it isn't notifiable in England, though Wales can treat it differently, so check if unsure. Before any faceplate is loosened, the circuit must be switched off at the consumer unit and proved dead with a tester – this is the electrician's job, not yours. Book this in before panelling starts, because moving sockets afterwards means taking panels back off.

KNOW THE RULES

Moving a socket or switch on an existing circuit is not notifiable in England but is still an electrician's job; in Wales it can be notifiable, so check if unsure. The circuit must always be isolated at the consumer unit and proved dead before any faceplate is removed.

PH-04Fit the dado railFollow 'Fit a dado rail' to cut, mitre, and fix the rail at the height you marked earlier. Work round the room in one direction so the final joint lands in the least visible corner. Check the line with a level every metre or so, since a rail that drifts even a few millimetres over a long wall is obvious once painted.

PH-05Fit the panelling below the railFollow 'Fit shaker-style wall panelling' to build and fix the panel grid between the skirting and the dado rail. Work one wall at a time, cutting panelling neatly around any sockets or switches the electrician has already moved forward. This phase usually takes longer than expected, since each panel needs repeated fitting and adjusting, so allow roughly a full day per wall on an average-sized room.

PH-06Caulk and fill all the gapsFollow 'Caulk gaps around skirting and architrave' to seal the joins between the panelling, the dado rail, the skirting, and the wall. Run a continuous bead along every joint rather than spot-filling, since gaps that look fine unpainted stand out badly once painted. Let the caulk cure fully before moving on to painting, usually at least 24 hours, so check the tube for drying time.

PH-07Paint the skirting, rail, and panellingFollow 'Paint skirting boards' for technique, and use the same approach on the dado rail and panelling. Apply a primer or undercoat first if the panelling is bare MDF, then two topcoats for a durable finish. Check in good light for missed caulk lines or filler patches before the final coat, since these show up badly once painted.
