How to batten a wall

Video by Tommy's Trade Secrets. This walk-through is based on the video "Tommy's Trade Secrets - How to Batten a Wall" from Tommy's Trade Secrets, which covers the process of fixing timber battens to a masonry wall ahead of dry lining. It is a short, practical video that gives a clear sense of batten spacing and how to pack out an uneven wall to get a flat result.

1. Decide on batten size and spacing

For plasterboarding over, 47 x 25 mm (roughly 2 x 1 inch) treated timber battens are the standard choice. If you are adding insulation behind the board, you may want 47 x 47 mm battens to create a deeper cavity — 50 mm rigid insulation board fits neatly between battens at that depth.

Batten spacing needs to line up with your sheet material. For 1200 mm wide plasterboard, set vertical battens at 400 mm or 600 mm centres so every sheet edge and the middle of each sheet lands on a batten. Always fit a horizontal batten at floor level, one at ceiling level, and one at mid-height — these give the sheets something to bear against top and bottom as well as fixing points for skirting and coving later.

2. Check for pipes, cables, and damp before you fix anything

Before drilling a single rawlplug hole, run a cable and pipe detector across the full wall. Old houses in East Kent — particularly Victorian terraces and inter-war semis — often have surface-run cables, buried gas pipes, or redundant services that do not show on any plan. Hitting a live cable with a masonry bit is not an experience worth having.

Also check the wall for damp. If there is a persistent damp patch, battening over it will trap moisture and the timber will rot within a few years. Deal with the damp first — whether that is repointing outside, improving drainage, or applying a waterproof tanking coat — then batten. It depends on the cause, but skipping that step will come back to haunt you.

3. Mark out the batten positions with a chalk line

Use a chalk line or a long level to mark vertical lines at your chosen centres across the wall. Start from one corner and work across, double-checking that the first and last battens are plumb before snapping any lines. If the corner itself is out of plumb — which is common in older properties — use the first batten as your reference, not the corner.

Mark the horizontal battens too, using a level. The top horizontal should be tight to the ceiling (or just below a coving line if you are adding coving later). The bottom horizontal should sit just above finished floor level. Getting these right at the start means every vertical batten can be cut to the same length, which keeps things moving quickly.

4. Fix the battens and pack out any hollows

Drill and rawlplug the wall at roughly 600 mm intervals along each batten line. Use 65 mm or 75 mm frame fixings, depending on how hard the masonry is. For softer brick — fairly common in older East Kent houses — use a sleeved anchor rather than a standard rawlplug, as the softer material can strip out under load.

This is where a lot of people struggle — masonry walls are rarely truly flat, and if you just screw the battens straight to the wall without packing out the hollows, you end up with a bowed framework that produces a bowed finished surface. Slip small pieces of hard plastic packers or folded DPC membrane behind the batten at each fixing point and check with a long straight-edge or level as you go. Take your time on this step; it is what separates a professional-looking result from one that moves in the light.

5. Fit noggins and deal with internal and external corners

Noggins are short horizontal pieces of batten fitted between the vertical members to provide mid-point support and give you somewhere to fix sheet edges where they do not fall on a full batten. Cut them to fit snugly and skew-nail or screw them in from each side. You will need noggins anywhere a horizontal sheet joint falls, as well as around window and door reveals.

At internal corners, one batten butts tight into the corner and the adjacent batten fixes flat to the wall, overlapping the edge of the first. This gives a solid fixing point for both sheets meeting at that corner. External corners are the trickier one — fit a full-height vertical batten right at the corner on each wall, so the board edges have support all the way up. Those corners will take knocks, so solid fixing matters.

6. Check the whole framework before boarding begins

Once all the battens and noggins are in, run a long straight-edge (a 2.4 m batten works well) over the whole framework in several directions. Any high spots or low spots that will transfer through to the finished surface need to be dealt with now. High spots on individual battens can be planed back; low spots need packing out. It only takes ten minutes but saves hours of remedial work later.

Also check that the framework is secure. Give each batten a firm push and pull — nothing should move. If a fixing feels loose, add another screw nearby rather than trying to over-tighten the existing one, which will just strip the rawlplug. Once you are happy everything is solid and flat, you are ready to start boarding.

When to call a handyman

Call Richard if the wall is awkward — around a chimney breast, full of pipework, or badly out of plumb — or if the room is large and you need the framework completed quickly before other trades arrive. Getting battens flat and level is one of those jobs that is straightforward in principle but can eat up a whole day if the masonry is uncooperative. Richard covers Sandwich and the surrounding East Kent villages, so get in touch and he can give you a realistic idea of what is involved.
