Wood Panelling: How to Line Interior Walls with Timber

Interlocking tongued and grooved boards can be fixed to any type of wall. Vertical boards tend to make a room look higher, horizontal boards longer.

Screw or nail 50 x 25 mm (2 x 1 in) timber battens to the wall, in the opposite direction to the run of the boarding, to provide the base for fixing the boards.

If the plaster is sound and not too thick, masonry nails provide the quickest method of securing the battens. First drive the nails into a batten, then hold the batten against the wall and drive the nails home. If the plaster is thick or crumbly, fasten the battens with screws and wallplugs.

Fix the battens 400 mm (16 in) apart, at least up to shoulder height. Above this level the spacing can be increased to 600-900 mm (2-3 ft).




Remove existing architraves from around door and window openings and fasten battens in their place. Remove skirting boards. If the walls tend to be damp, treat the battens with wood preservative and sandwich building paper between the wall and battens.

Bring the front surfaces of the battens to a uniform vertical plane by inserting plywood or hardboard packing behind them.

A nominal 100 mm wide tongued and grooved board covers only 85 mm (3-1/2 in) when interlocked. A wall 3500 mm (12 ft) long and 2500 mm (8 ft) high requires just under 43 boards, each 2500 mm long: ie, 108 m. It would be advisable to order at least 115 m. to allow for waste.

When fastening boards upright, start from a corner. Pin the first board up and check that the edge further from the corner is vertical. Repeat on the other arm of the corner, planing the inside edge of the second board so that it butts neatly.

Interlock the boarding as tightly as possible, since it is bound to shrink considerably during initial drying. Fasten with secret nails through the tongues into the battens. Alternatively, nail through the boards, punch the heads and fill the holes with plastic wood.

To fit a board ceiling, fix the boards directly to the joists with 40 mm (1-1/2 in) pins. Butt-joint boards for long spans, centring joints beneath a joist. Short lengths must cover at least two joists. Do not let joints in adjacent boards coincide.

Clad existing ceilings, provided laths are free from woodworm, by fixing through the plaster into the joists. Locate the joists by drilling small holes through the plaster at each side of the room and ruling in the centre lines. If boards are to run in line with the joists, fix battens at 90° to the joists with 60 mm (2-1/2 in) cut nails, and pin the boards to the battens.

At electrical sockets and light switches, re-route the existing wiring into new metal mounting boxes surrounded by a framework of battens. Stop the boards so that switch and socket plates cover the ends.
